TeraTerm has some great macro options that help when logging output. Where I am having an issue is running the macro and automagically logging in to the telnet session. When the connection is made, the device immediately requires the following, in a specific order. If I understood you correctly, you run ipconfig on your computer to see IP address of your default gateway then trying to connect to it with Teraterm? If yes, then just IP address of DG in teraterm SSH and connect. If cannot connect try to ping it. If it is pingable then first try to connect through Telnet perhaps SSH not enabled at all on router. Teraterm log and replay functions Bases on stack overflow article logging - Change log file name of teraterm log you can add timestamp in the long, which is mandatory if you open several terminals with logging. I would like to change the default log file name of teraterm terminal log. The garbage characters include escape sequences that cause Teraterm to give what appears to be corrupted text for regular text (after the boot time garbage characters are finished). There REALLY needs to be an Option to disable code/character page changes and certain ESC commands for VT100, so the boot time garbage does not affect TeraTerm.

Connects.

Remarks

If MACRO is not linked to Tera Term, this command runs Tera Term with <command line parameters>, and links it to MACRO. For example:

If MACRO has already been linked to Tera Term and Tera Term is not connected to the host, this command causes Tera Term to connect to the host specified by <command line parameters>.

If MACRO has already been linked to Tera Term and Tera Term has already been connected to the host, this command is ignored.

As a result of this command, the system variable 'result' is set to one of the following values depending on the link and connection status:

ValueStatus
0Link to Tera Term has not been made.
1Connection to the host has not been made, but link to Tera Term has been made.
2Both connection and link have been made.

To test the current link and connect status before executing the 'connect' command, use the 'testlink' command.

Teraterm

Communication commands except 'connect', 'cygconnect' and 'testlink' can not be executed before the link is established.

Connection method

There are 3 types of connection you can establish from Tera Term macro:

  • Telnet connection (port 23)
  • SSH1 or SSH2 connection (port 22)
  • General connection
  • Connection via COM port

Telnet connections

Using /nossh is strongly recommended. Without this parameter Tera Term will start connecting with the same method (telnet or SSH) that was used during last time when teraterm.ini file was saved. In case it was SSH than your macro will try to connect via SSH and will eventually fail.

SSH connections

This way will start SSH connection without defining whether SSH1 or SSH2 has to be used.

Parameters /1 and /2 force to use SSH1 or SSH2 method.

Wintergrasp. Note: path to /keyfile should be relative to Teraterm directory. Absiolute path does not work.

Above 9 ways allow to skip popup dialog and pass username and password directly from macro. Please note that /auth=password or /auth=publickey or /auth=challenge is the parameter saying that authentication will be done by entering password or private-key-file thus you should not replace the word 'password' or the word 'publickey' in it with actual password.

Above 3 ways allow to skip popup dialog and pass username directly from macro.

Above 9 ways pass username and authentication method directly from macro, and the popup asks for password.

General connection

Note: This option value is connecting timeout value(per seconds). Connecting to myserver could be canceled after timeout has occurred with the specified value. Conversely, no action if the value is zero. The default value is zero. Also this value would be saved as `ConnectingTimeout' entry in teraterm.ini file.

Connections via COM port

Here x represents COM port number. For example to connect via COM port 1 the command will look like: connect '/C=1'

Examples

Note

  1. In these examples parameters shown with Italic font have to be replaced with their actual values.
  2. The password can contain space character. To represent space inside the password replace it with '@' character. If '@' character itself is part of the password than it has to be replaced with 2 consecutive '@' characters '@@'.
  3. Please remember that entering actual username and password in Tera Term macro will cause them to be stored as an open text and it is your responsibility to keep such macro is secure location.
  4. When a user re-connect the remote host soon after disconnecting the server, a user could not connect the server. For more detail, refer to 'here'.

Macro command 'connect' syntax description

Three types of connections
There are 3 types of connection you can establish from TeraTerm macro:Teraterm Log

- Telnet connection (port 23)
- SSH1 or SSH2 connection (port 22)
- Connection via COM port

Telnet connections

Quote:

connect 'myserver:23 /nossh'

or

Quote:

connect 'myserver:23 /telnet'

or

Teraterm LogQuote:

connect 'myserver:23'


Using /nossh is strongly recommended. Without this parameter TeraTerm will start connecting with the same method (telnet or SSH) that was used during last time when teraterm.ini file was saved. In case it was SSH than macro will try to connect via SSH and will eventually fail.

SSH connections

Quote:

connect 'myserver /ssh'


This way will start SSH connection without defining whether SSH1 or SSH2 has to be used.

Teraterm LogQuote:

connect 'myserver /ssh /1'

or

Quote:

connect 'myserver /ssh /2'


Parameters /1 and /2 force to use SSH1 or SSH2 method.

Quote:

connect 'myserver /ssh /auth=password /user=username /passwd=password'

or

Quote:

connect 'myserver /ssh /1 /auth=password /user=username /passwd=password'

or

Quote:

connect 'myserver /ssh /2 /auth=password /user=username /passwd=password'

or

Quote:

connect 'myserver /ssh /auth=publickey /user=username /passwd=password /keyfile=private-key-file'

or

Quote:

connect 'myserver /ssh /1 /auth=publickey /user=username /passwd=password /keyfile=private-key-file'

Teraterm Log Open

or

Quote:

connect 'myserver /ssh /2 /auth=publickey /user=username /passwd=password /keyfile=private-key-file'


Above 6 ways allow to skip popup dialog and pass username and password directly from macro. Please note that /auth=password or /auth=publickey is the parameter saying that authentication will be done by entering password or private-key-file thus you should not replace the word 'password' or the word 'publickey' in it with actual values. Only the words shown above with italic font have to be substituted.

Important note: The password can contain space character. To represent space inside the password replace it with @ character. If @ character itself is part of the password than it has to be replaced with 2 consecutive @ characters @@.

Please remember that entering actual username and password in TeraTerm macro will cause them to be stored as an open text and it is your responsibility to keep such macros in secure place.

A little bit better practice is to use getpassword and passwordbox commands that store encrypted passwords in the file.

Quote:

connect 'myserver /ssh /auth=password /user=username /ask4passwd'

or

Quote:

connect 'myserver /ssh /1 /auth=password /user=username /ask4passwd'

or

Quote:

connect 'myserver /ssh /2 /auth=password /user=username /ask4passwd'

or

Quote:

or

Quote:

connect 'myserver /ssh /1 /auth=publickey /user=username /ask4passwd /keyfile=private-key-file'

or

Quote:

connect 'myserver /ssh /2 /auth=publickey /user=username /ask4passwd /keyfile=private-key-file'


Above 6 ways pass username and authentication method directly from macro, and the popup asks for password.

Connections via COM port

Quote:

connect '/C=x'


Here x represents COM port number. For example to connect via COM port 1 the command will look like: connect '/C=1'

About setsync
It is highly recommended to use the macro command

Quote: Tcode for spool request in sap.

setsync 1


right after the command connect. This command switches TeraTerm into synchronous communication mode in which the buffer never overflows. See TeraTerm Macro help for more details.
