Saving the Running-Configuration in Tera Term

Filed under: Tech Tips — cciepursuit @ 8:45 am

Tera Term is my telnet client of choice.  I will soon be making the move to SecureCRT as that is the client used on the CCIE lab.  I’ve used Tera Term for years, so the move may be a painful one.

Here’s a step by step method for saving your configurations in Tera Term:

1) Type “terminal length 0”.  This will stop pausing when you do a “show run” so that you don’t have to keep hitting the spacebar.

Step 1

2) In Tera Term go to “File” -> “Log…” and then enter a filename for your configuration in the form of “filename.txt”.  Remember the .txt or you’ll end up with a file that you cannot open.  If this happens, simply rename the file so that it ends with .txt

Step 2

Step 2

3) Click “Open”.  You’ll be returned to your telnet session, but you should notice a new window on your Taskbar.

Step 3

4) Type “show run”.  As soon as the configuration has been displayed, click on the “Tera Term: Log” window and then click “Close”.

Step 4

5) Finally, be sure to reset your terminal length (if you like) “term len 24”

Step 5

You can skip setting the terminal length to zero, but you’ll need to hit the spacebar to scroll through each screen of the configuration.  Also, your configuration text file will/might end up with garbage characters and other text that the router will choke on if you paste it in configuration mode:

Text Without “Term Len 0”

interface Serial0/1
 no ip address
 –More–         router bgp 123
 no synchronization
 bgp log-neighbor-changes
 neighbor remote-as 123

You can use the above method to save “show tech” or any commands or output from any telnet session.
