Can you suggest a Telnet replacement for Linux/AIX?

davee · 06-24-2003, 02:24 AM

I'm wanting to remove telnet access to our Linux and AIX servers, because of unencripted transmission of data. Can anyone suggest an equivalent thiat:

* Will work will both OS's
* Can be connected to by Windows clients
* Is secure

It's really annoying me that you can't seem to direct telnet through another port, ie 443.

Thanks in advance for your input...

I think ssh should be adequate.

I'm not sure if SSH works on AIX, but I wouldn't ever use telnet in favor of SSH.

rmartine; creepy, I'm in SLO too

So tell me more about SSH - can a windows client connect to it via a telnet session? Is there any SSH client software required on the user's PC?

Think of SSH as a secure telnet client/server. Windows machines can use a program called "Putty" to connect (has a wide variety of uses, actually) to an SSH server. The program is rediculously small, and has no installation, which makes it easy to roll out on client machines.

OK, thanks for that - where do you recommend I get putty (officially!)

(IIRC)

It's just struck me that it's puTTY (bad pun!)

Glad I could help

Just as a follow up, that worked 100%

Thanks again...

...now for the AIX implementation!

either use ssh or use kermit on the aix machine and set it up to control the telnet port and the only one that can connect is a kermit protocal system. It works nice and is almost as secure as ssh ( I did say ALMOST).
