    The Serial panel allows you to configure options that only apply when PuTTY is connecting to a local serial line. You might use this, for instance, if you had set up an SSH port forwarding in one PuTTY session so that connections to some arbitrary port (say, localhost port 10022) were forwarded to a second machine's SSH port (say, foovax port 22), and then started a second PuTTY connecting to the forwarded port. To configure manual host keys via the GUI, enter some text describing the host key into the edit box in the Manually configure host keys for this connection container, and press the Add button. Check out all the Tasmota features and ways to integrate it with other platforms. The latest merged development code is compiled hourly. The usual authorisation method used for this is called MIT-MAGIC-COOKIE-1. This character set is documented in the SUPDUP protocol definition. This entire panel is only relevant to SSH protocol version 2; none of these settings affect SSH-1 at all. The following options allow particularly sensitive portions of unencrypted packets to be automatically left out of the log file. because it needs to do its own authentication using a special private key) then you can untick one or the other of these boxes. ITS extended ASCII is used by ITS and Lisp machines, whilst WAITS is only used by the WAITS operating system from the Stanford AI Laboratory. In the default configuration, when the server sends the character with ASCII code 7 (Control-G), PuTTY will play the Windows Default Beep sound. In addition to SSH itself, PuTTY also supports a second protocol that is derived from SSH. Of course you can also drag the window to a new size while a session is running. By default, all of the available modes are listed as Auto, which should do the right thing in most circumstances. This is not enabled by default. the Backspace key on the keyboard will send the. In order to send the right control sequences to each one, the server will need to know what type of terminal it is dealing with. The cookie data is sent over an unencrypted X11 connection; so if you allow a client on a third machine to access the virtual X server, then the cookie will be sent in the clear. For instance, Dragon NaturallySpeaking requires it both to open the system menu via voice, and to close, minimise, maximise and restore the window. Even though we havent configured anything yet, there is a basic configuration. If the labelling isn't visible on the PCB please refer to the devices flashing guide or search the Internet for correct pin locations. The keepalive option (Seconds between keepalives) allows you to configure PuTTY to send data through the session at regular intervals, in a way that does not disrupt the actual terminal session. On many devices the installed control button is connected to GPIO0 and GND, making entering Programming Mode easy. The second time I do it, we jump back to enable mode and exit the configuration mode: Here is a picture to help you visualize the different modes and how to move from one to another: We entered a couple of commands but once we pull the power plug, everything is gone. Depending on the phone, it will take you to the Tasmota configuration page automatically, or you will get a prompt to sign in to Wi-Fi network or authorize. Make sure that the RX pin is connected to the TX pin between the serial adapter and your ESP device, and vice versa. This allows an attacker to fake keypresses and potentially cause your server-side applications to do things you didn't want. In case the network name or password were entered incorrectly, or it didn't manage to connect for some other reason, Tasmota will return to the "Wi-Fi parameters" screen with an error message. The SSH panel allows you to configure options that only apply to SSH sessions. If you don't know what any of this means, you probably don't need to fiddle with it. Once you enter the interface configuration, the switch does not show you which interface you selected. If it is disabled, PuTTY will ignore any control sequences sent by the server which use the extended 256-colour mode supported by recent versions of xterm. The Kex panel (short for key exchange) allows you to configure options related to SSH-2 key exchange. There are also debug commands. The Browse button will let you look around your file system to find the right place to put the file; or if you already know exactly where you want it to go, you can just type a pathname into the edit box. For this reason, this policy is configurable. Not all SSH servers work properly. There are some forms of attack against an SSH client user which work by terminating the SSH authentication stage early, and then doing something in the main part of the SSH session which looks like part of the authentication, but isn't really. The X11 panel allows you to configure forwarding of X11 over an SSH connection. A block cursor becomes an empty box when the window loses focus; an underline or a vertical line becomes dotted. If this option is enabled, then PuTTY will look for Pageant (the SSH private-key storage agent) and attempt to authenticate with any suitable public keys Pageant currently holds. PuTTY supports a set of key exchange methods that also incorporates GSSAPI-based authentication. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection. Application Keypad mode is a way for the server to change the behaviour of the numeric keypad. If the user running PuTTY has current Kerberos V5 credentials, then PuTTY will select the GSSAPI key exchange methods in preference to any of the ordinary SSH key exchange methods configured in the preference list. If a private key file is specified here with Pageant running, PuTTY will first try asking Pageant to authenticate with that key, and ignore any other keys Pageant may have. Therefore, you might find that keepalives help connection loss, or you might find they make it worse, depending on what kind of network problems you have between you and the server. PuTTY offers the alternative protocol XDM-AUTHORIZATION-1. Backup the current firmware with the following command: Erase the complete flash memory holding the firmware with the following command: When the command completes the device is not in programming mode anymore. It requires Python, if you do not have an installed copy of Python 2.x or 3.x download and install it from https://www.python.org. You can remove keys again with the Remove button. By ticking this box, you can disable bidirectional text display, so that PuTTY displays text from left to right in all situations. The main colour control allows you to specify exactly what colours things should be displayed in. Each option on this panel applies to more than one protocol. The format is a pair of numbers separated by a comma, for instance, 38400,38400. The two keyboard options each come with a corresponding key to copy to the same clipboard. In Windows just double click the downloaded file and it'll start, no installation required. For instance, in the Destination box, you could enter popserver.example.com:pop3. PuTTY can only perform the GSSAPI-authenticated key exchange methods when using Kerberos V5, and not other GSSAPI mechanisms. (If you specify a literal Internet address, it will use whichever protocol that address implies. The SSH-2 protocol does contain such a mechanism, but not all SSH servers support it. In these contexts, the operating system will already have guaranteed that each of the two communicating processes is owned by the expected user (so that no authentication is necessary), and that the communications channel cannot be tapped by a hostile user on the same machine (so that no cryptography is necessary either). When we want to make changes to interfaces or console settings, we have to dive into one of the configuration sub modes. If you made changes to the console and logged out, you should be able to log back in with the new username and password that have been configured. Much of this panel is only relevant to SSH protocol version 2; SSH-1 only supports one type of host key. This prevents you from having to check and confirm a new host key for a server you already had one for (e.g. If this bug is detected, PuTTY will never initiate a repeat key exchange. This is similar to the effect you get with port forwarding or X11 forwarding, in which a PuTTY whose terminal session has already finished will still remain open so as to keep serving forwarded connections. An example is Debian bug #991958, in which a connection going over the console of a User Mode Linux kernel can lose outgoing data before the kernel has fully booted. because the server has generated an alternative key of a type higher in PuTTY's preference order, or because you changed the preference order itself). If you select Both, the font and the colour will both change. If you see anything between [] you only have to press enter. If you find this feature inconvenient, you can disable it using the Disable xterm-style mouse reporting control. Choose according to your jumper wire connectors. If you want to modify the code or default settings and compile your own Tasmota firmware. You can check this using a command such as infocmp: If you do not see colors#256 in the output, you may need to change your terminal setting. If the box is empty (as it usually is), then PuTTY's automated host key management will work as normal. ITS means ASCII extended with printable characters in the control character range. An ignore message (SSH_MSG_IGNORE) is a message in the SSH protocol which can be sent from the client to the server, or from the server to the client, at any time. Between the brackets, you see confirm. Search for a Wi-Fi AP named tasmota_XXXXXX-#### (where XXXXXX is a string derived from the device's MAC address and #### is a number) and connect to it. If the flashing process is unable to start, disconnect the device and retry the steps. Enable local echo so that you can see what is typed and transmitted to the device. To disable remote printing again, choose None (printing disabled) from the printer selection list. In PuTTY's default configuration (Compromise), the right button pastes, and the middle button (if you have one) extends a selection. Application keypad mode (see section 4.4.6) and application cursor keys mode (see section 4.4.5) alter the behaviour of the keypad and cursor keys. Keepalives can make this sort of problem worse, because they increase the probability that PuTTY will attempt to send data during a break in connectivity. This option allows the SSH server to open forwarded connections back to your local copy of Pageant. The SSH protocol allows the client to send terminal modes for the remote pseudo-terminal. The Local username control allows you to specify what user name PuTTY should claim you have, in case it doesn't match your Windows user name (or in case you didn't bother to set up a Windows user name). PuTTY allows the server to send control codes that let it take over the mouse and use it for purposes other than copy and paste. Since most servers announce their software version number at the beginning of the SSH connection, PuTTY will attempt to detect which bugs it can expect to see in the server and automatically enable workarounds. The Display scrollbar options allow you to hide the scrollbar (although you can still view the scrollback using the keyboard as described in section 3.1.2). Most servers send two control characters, CR and LF, to start a new line of the screen. Connect your serial-to-USB adapter or NodeMCU/D1 mini to the computer. In fact, in the Unix version of PuTTY, when a sharing upstream records Sharing this connection at [pathname] in the Event Log, it's possible to connect another instance of PuTTY directly to that Unix socket, by entering its pathname in the host name box and selecting Bare ssh-connection as the protocol!). WebBIOS setting: AdvancedSerial Port Console RedirectionCOM1-Console Redirection Settings & EMS-Console Redirection Settings Please set the Putty Connection Type = Serial, and Speed are equal with Bits per second, and click Open. Heres how you enter configuration mode: First, you need to make sure you are in enable mode. Once the overload feature is active, further bells will have no effect at all, so the rest of your binary file will be sent to the screen in silence. With this box ticked, the mouse will always do copy and paste in the normal way. For example, I just used copy running-config startup config but I dont have to type the entire thing. This will make the cursor jump to the start or end of the line. In the Source port box, you can also optionally enter an IP address to listen on, by specifying (for instance) 127.0.0.5:79. Key exchange occurs at the start of an SSH connection (and occasionally thereafter); it establishes a shared secret that is used as the basis for all of SSH's security features. If this option is enabled, then pressing Alt-Enter will cause the PuTTY window to become full-screen. This is technically a violation of the SSH-1 specification, and so PuTTY will only do it when it cannot use standards-compliant ignore messages as camouflage. However, sometimes it will make mistakes; if the server has been deliberately configured to conceal its version number, or if the server is a version which PuTTY's bug database does not know about, then PuTTY will not know what bugs to expect. Version 2 of the SSH protocol also provides a similar mechanism, which is easier to implement without security flaws. On the switch, you will find one or two physical connectors for the console. E.g. PuTTY has the ability to change the window title in response to commands from the server. You will need a file called (say) PUTTY.BAT which imports the contents of a file into the Registry, then runs PuTTY, exports the contents of the Registry back into the file, and deletes the Registry entries. 4.17.5 Sharing an SSH connection between PuTTY tools. Hence, the Rlogin .rhosts mechanism is completely useless for securely distinguishing several different users on a Windows machine. However, not all applications will see it that way. Connect your device to a power source and grab your smartphone (or tablet or laptop or any other web and Wi-Fi capable device). If you enable this option, then not only will PuTTY be able to log in automatically to a server that accepts your Kerberos credentials, but also you will be able to connect out from that server to other Kerberos-supporting services and use the same credentials just as automatically. (In fact, the passphrase for your public key should not be sent to any server.). Hi from Paris, This is a cryptographically authenticated protocol: the data sent by the X client is different every time, and it depends on the IP address and port of the client's end of the connection and is also stamped with the current time. If you are viewing part of the scrollback when the server sends more text to PuTTY, the screen will revert to showing the current terminal contents. Rlogin allows an automated (password-free) form of login by means of a file called .rhosts on the server. There are many terminal emulator applications. If it believes the server to have this bug, PuTTY will stop using ignore messages. The value is measured in seconds; so, for example, if your firewall cuts connections off after ten minutes then you might want to enter 300 seconds (5 minutes) in the box. These show commands only produce static information. The Appearance configuration panel allows you to control aspects of the appearance of PuTTY's window. The SSH-2 protocol specification recommends a limit of at most 1 gigabyte. The Behaviour configuration panel allows you to control aspects of the behaviour of PuTTY's window. PuTTY contains native support for a few well-known such libraries (including Windows' SSPI), and will look for all of them on your system and use whichever it finds. If you delete a remote port forwarding, note that: If you ask to delete a remote port forwarding and PuTTY cannot make the server actually stop listening on the port, it will instead just start refusing incoming connections on that port. If forwarding of GSSAPI credentials is enabled, PuTTY will try to rekey as necessary to keep the delegated credentials from expiring. How you acquire a public key in this format is server-dependent; on an OpenSSH server it can typically be found in a location like. If you press the Close button in a PuTTY window that contains a running session, PuTTY will put up a warning window asking if you really meant to close the window. Note that if you are using SSH-1 and the server has a bug that makes it unable to deal with SSH-1 ignore messages (see section 4.26.12), enabling keepalives will have no effect. Not all terminals agree on what colour to turn the screen when the server sends a clear screen sequence. The COM port will depend on your computer, it might be COM1 but if you are unsure, check the device manager in Windows. Most Unix-style Telnet servers don't mind whether they receive Telnet New Line or Control-M; some servers do expect New Line, and some servers prefer to see ^M. If this bug is enabled when talking to a correct server, the session should still function, but may be less secure than you would expect. If the name is passed on to the proxy without PuTTY looking it up, it will never know the IP address and cannot check it against your list. Change the number of rows and columns: the font size will not change. The original SOCKS 4 protocol does not support proxy-side DNS. This allows you to select whether to use SSH protocol version 2 or the older version 1. WebMaltese dogs for adoption near chicago, illinois, usa, page 1 (10 per page) puppyfinder.com is proud to be a part of the online adoption community. The third setting, and the default one, is Only on clean exit. " I get a new info" How to use the terminal emulator (Putty) to connect to your switch. SKU: MN0213517The Kawasaki Sax -A-Boom Soundfont (Jack Black) by Wrapped Tomato Soup with Cheese Uploaded on Sep 23, 2020 (and last updated on Dec 27, This will usually substantially reduce the size of the resulting log file. If the flash was successful it will display: Unplug your serial programming adapter or device and plug it back in or connect to another power source. If this bug is enabled when talking to a correct server, the session will work correctly, but download performance will be less than it could be. See section 3.11.3.9. This can cause PuTTY sessions to be unexpectedly closed by the firewall if no traffic is seen in the session for some time. These options let you configure the way PuTTY keeps text after it scrolls off the top of the screen (see section 3.1.2). Use font in OEM mode only is more reliable than that, but can miss out other characters from the main character set. Select the . Normally, when PuTTY receives character 127 (^?) Some adapters can be switched between 3.3V and 5V for the data pins, but still provide 5V on the power pin which will irreparably destroy your device. In all these Cisco lessons, you will see a LOT of show commands that I use to explain things. You can test whether your device is in Programming Mode by attempting to read information from the ESP82xx chip. If the Auto option is selected, the PuTTY tools will decide whether to specify that mode to the server, and if so, will send a sensible value. What did I miss ? Bell overload mode is always deactivated by any keypress in the terminal. and configuring the server to expect it, because that allows applications such as emacs to use Control-H for help. In the SSH-1 protocol, it is impossible to change username after failing to authenticate. It is very unlikely that this behaviour would ever cause problems, but if it does you can change it by enabling Consider proxying local host connections. His hero costume consists of a full-body monochrome [3] suit along with a yellow cape, a belt with the letter. There are controls in the Tunnels panel to change this: This switch allows you to select a specific Internet protocol (IPv4 or IPv6) for the local end of a forwarded port. Num Lock stops behaving like Num Lock and becomes another function key. If you are using X11 forwarding, the virtual X server created on the SSH server machine will be protected by authorisation data. If there is a specific host you want to store the details of how to connect to, you should create a saved session, which will be separate from the Default Settings. Windows often only has two mouse buttons, so when run on Windows, PuTTY is configurable. For this reason PuTTY defaults to active mode. Versions below 2.3 of OpenSSH require SSH-2 public-key authentication to be done slightly differently: the data to be signed by the client contains the session ID formatted in a different way. This type of security is rudimentary since Tasmota doesn't use HTTPS, do not expose your device outside of your local network. If a Telnet proxy server prompts for a username and password before commands can be sent, you can use a command such as: This will send your username and password as the first two lines to the proxy, followed by a command to connect to the desired host and port. ), With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. The Cursor blinks option makes the cursor blink on and off. It means someone else already deleted the VLAN information and you can continue. Web3.8.1 Starting a session from the command line. This might be useful if you are deliberately using control character pasting as a simple form of scripting, for instance. PuTTY supports a variety of different encryption algorithms, and allows you to choose which one you prefer to use. To enable this feature, just tick the box Share SSH connections if possible. In some cases you will need to solder wires directly on the chip's pins which requires some experience and good soldering equipment. However, you can work around this with a couple of batch files. By default, PuTTY displays this message before prompting for a password or similar credentials (although, unfortunately, not before prompting for a login name, due to the nature of the protocol design). (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.). PuTTY allows the server to send xterm control sequences which modify the title of the window in mid-session (unless this is disabled - see section 4.6.5); the title string set here is therefore only the initial window title. In this string, you can use \n to represent a new-line, \r to represent a carriage return, \t to represent a tab character, and \x followed by two hex digits to represent any other character. At the top of the page you can select one of the discovered Wi-Fi networks or have Tasmota scan again. Setting this option stops this filtering; on paste, any character on the clipboard is sent to the session uncensored. This feature should only be needed if you have trouble passing environment variables to quite an old server. If a value is specified, it will be sent to the server under all circumstances. Most types of proxy (HTTP, SOCK5, SSH, Telnet, and local) will have host names passed straight to them; SOCKS4 proxies will not. This excludes both of the above ranges at once. You can disable this behaviour by turning off Reset scrollback on display activity. PuTTY supports a variety of SSH-2 key exchange methods, and allows you to choose which one you prefer to use; configuration is similar to cipher selection (see section 4.20). Connect your device to the serial-to-USB adapter or plug in NodeMCU/D1 mini. Another effect of GSSAPI key exchange is that it replaces the usual SSH mechanism of permanent host keys described in section 2.2. Therefore your smartphone will automatically be disconnected and should connect back to its data network. If this is set to zero, PuTTY will not rekey due to elapsed time. The Window configuration panel allows you to control aspects of the PuTTY window. See chapter 9 for more information about Pageant in general. There is another command for that: The show mac address-table dynamic command tells us all MAC addresses that the switch has learned. SSH proxying can use all the same forms of SSH authentication supported by PuTTY for its main connection. If you're intimidated by soldering there are 3D printed jigs available for different modules and devices. Saved sessions are stored in the Registry, at the location. Tapping on the AP name should also open the configuration page. The Cursor appearance option lets you configure the cursor to be a block, an underline, or a vertical line. The Keyboard configuration panel allows you to control the behaviour of the keyboard in PuTTY. If this bug is enabled when talking to a correct server, the session will succeed, but keepalives will not work and the session might be more vulnerable to eavesdroppers than it could be. By default no port forwardings are set up, so this list is empty. If PuTTY is configured to treat data from the server as encoded in UTF-8, then by default it disables the older VT100-style system of control sequences that cause the lower-case letters to be temporarily replaced by line drawing characters. Lets try the clock command again: The switch tells us that the command is incomplete. Note that if you are doing DNS at the proxy (see section 4.16.3), you should make sure that your proxy exclusion settings do not depend on knowing the IP address of a host. If Pageant is running and contains any SSH-1 keys, PuTTY will normally automatically try RSA authentication before falling back to passwords, so these servers will crash when they see the RSA attempt. First, it will initialize the flash memory: Initializing the flash memory is required since it contains the IOS image (Operating System) of the switch. The command is typed correctly but the problem here is that this is a command for the enable mode, not the configuration mode. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. The installer will scan for Wi-Fi networks and select the strongest one. On X, you can also enter a selection name of your choice. After typing line console 0 I get CiscoPOE(config-line)# password Molenaar The GSSAPI subpanel of the Auth panel controls the use of GSSAPI authentication. Some types of session need local line editing, and many do not. With this option disabled, screen clearing is always done in the default background colour. However, if this is wrong for your server, you can select a different character set using this control. If you find an application on which the Home and End keys aren't working, you could try switching this option to see if it helps. In some environments, such as the networks of large organisations implementing single sign-on, a more sensible default may be to use the name of the user logged in to the local operating system (if any); this is particularly likely to be useful with GSSAPI key exchange and user authentication (see section 4.22 and section 4.18.1.1). and newer Windows guests are known to work fine. BSD implementations did not change, and the standard was not corrected. This only works because Unix systems contain a safeguard to stop a user from pretending to be another user in an Rlogin connection. The effect of this is that if you paste into (say) a word processor, the text will appear in the word processor in the same font, colour, and style (e.g. Here are some of the things we discussed: I hope this lesson has been useful, the best thing to do now is to boot up a switch and try all of this by yourself. If you are not running Pageant, this option will do nothing. There are some Unicode characters whose width is not well-defined. If the operating system does not receive a response to a keepalive, it may send out more in quick succession and terminate the connection if no response is received. By default bold is indicated by colour, so non-bold text is displayed in light grey and bold text is displayed in bright white (and similarly in other colours). (However, Ctrl-Alt will never act as a Compose key, regardless of the setting of AltGr acts as Compose key described in section 4.4.8.). Some notable modes are described below; for fuller explanations, see your server documentation. With auto wrap mode off, the cursor will stay at the right-hand edge of the screen, and all the characters in the line will be printed on top of each other. If a server offers both versions, prefer 2. Here is how to do this: Above you can see that the > symbol changed to #. You can also save settings in mid-session, from the Change Settings dialog. In SSH-2, it is in principle possible to establish a connection without using SSH's mechanisms to identify or prove who you are to the server. Explicit support for this protocol is new in PuTTY 0.75. The Data bits box allows you to choose how many data bits are transmitted in each byte sent or received through the serial line. A PC power supply can be a source for 3.3V DC power. Cisco IOS keeps a history of previously entered commands. Another reason is if PuTTY's automated host key management is completely unavailable, e.g. You dont have to type confirm. Usually the same algorithm is used as at the start of the connection, with a similar overhead. The value is usually meaningless in a network environment, but PuTTY lets you configure it, in case you find the server is reacting badly to the default value. GSSAPI authentication is only available in the SSH-2 protocol. These usually control the server's expectation of the local terminal's behaviour. While this renegotiation is taking place, no data can pass through the SSH connection, so it may appear to freeze. By default PuTTY will use the UTF-8 encoding of Unicode, which can represent pretty much any character; data coming from the server is interpreted as UTF-8, and keystrokes are sent UTF-8 encoded. WebFirst you will need a serial terminal program that connects to Tasmota console over the serial connection you used to flash it. This chapter describes all the configuration options in PuTTY. TIS and CryptoCard authentication are (despite their names) generic forms of simple challenge/response authentication available in SSH protocol version 1 only. (These are still forms of authentication, even if you don't have to interact with them.). Others believe the screen should be cleared to whatever the server has selected as a background colour. If you have followed Hardware preparation, your device should be in Programming Mode and ready for a Tasmota firmware binary to be installed. This allows encrypted remote access. (This option is the Kerberos analogue of SSH agent forwarding; see section 9.4 for some information on that.). Esptool uses the serial interface to communicate with your device. If you use legacy CJK applications, and you find your lines are wrapping in the wrong places, or you are having other display problems, you might want to play with this setting. If this bug is enabled when talking to a correct server, communication will fail. Heres how to copy our running configuration to the startup configuration: Use the copy command to copy the running configuration to the startup configuration. The precise syntax of the value box depends on the mode. Then, whenever you start up a PuTTY session connecting to a particular host, it will try to reuse an existing SSH connection if one is available. This configuration setting is also visible on the Session panel, where it replaces the Port box (see section 4.1.1) if the connection type is set to Serial. If you use this feature in Plink, you will not be able to terminate the Plink process by any graceful means; the only way to kill it will be by pressing Control-C or sending a kill signal from another program. In a perfect world, we would remember everything and make no spelling errors. The controls in this box allow you to configure PuTTY to reuse an existing SSH connection, where possible. If you want to be able to close a window quickly, you can disable the Warn before closing window option. You can modify the currently active set of port forwardings in mid-session using Change Settings (see section 3.1.3.4). Rlogin connections have to come from port numbers below 1024, and Unix systems prohibit this to unprivileged processes; so when the server sees a connection from a low-numbered port, it assumes the client end of the connection is held by a privileged (and therefore trusted) process, so it believes the claim of who the user is. Esptool is the official Espressif tool for flashing ESP chips. (Use ^~ to get a literal ^. The next part of the Session configuration panel allows you to save your preferred PuTTY options so they will appear automatically the next time you start PuTTY. The correct state for many of these settings depends on what the server to which PuTTY is connecting expects. However, there are a variety of ways in which PuTTY can attempt to find appropriate characters, and the right one to use depends on the locally configured font. When this happens, remove whatever you typed in above the ^ symbol and use the question mark: This tells me that I should have typed November, not 11. The checkbox marked Sunken-edge border changes the appearance of the window border to something more like a DOS box: the inside edge of the border is highlighted as if it sank down to meet the surface inside the window. In this sense, for a server to refuse to accept a padded password packet is not really a bug, but it does make life inconvenient if the server can also not handle ignore messages. Authentication is not fully supported for all forms of proxy: If you are using the Telnet proxy type, the usual command required by the firewall's Telnet server is connect, followed by a host name and a port number. Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). You should replace a:\putty.rnd with the location where you want to store your random number data. By default, PuTTY filters out the more unusual control characters, only letting through the more obvious text-formatting characters (newlines, tab, backspace, and DEL). This makes the border a little bit thicker as well. The RGB values for that colour will appear on the right-hand side of the list box. The Features configuration panel allows you to disable some of PuTTY's more advanced terminal features, in case they cause trouble. The Bugs and More Bugs panels (there are two because we have so many bug compatibility modes) allow you to manually configure the bugs PuTTY expects to see in the server. When the remote server attempts to print some data, PuTTY will send that data to the printer raw - without translating it, attempting to format it, or doing anything else to it.
