Telnet monitoring

[latch]

Hi
I would like to know if there are tools which can monitor the content of telnet transactions. This tool should typically scan telnet transactions and log it juts like a email scanner does.
Would appreciate if tools on any OS are available?

Well, using telnet is insecure by default, due to everything going over the wire in plaintext. Because of this, you can probably use any packet sniffer to sniff the line, and see everything. Have a look at:

You should be able to confiure it to capture everything on port 23, and send it to a file. You can then write an additional script to get out what you need in that file.

There are also serial line sniffer utility:

If your telnet connections are over a serial line (using dumb terminals)

I hope you realize how insecure telnet is, and using these tools will prove that! Bruce Garlock
