Executing script/command after Telnet login

jerry_barajas — Tue, 09 Jun 2015 17:48:58 GMT

Hello Folks,

We have a server with HP-UX (HP-UX favc B.11.11 U 9000/800 146404690 unlimited-user license) that is used as a bridge to another server. It is very old.

this server operates as the following way:

Any user must login using a telnet client.
All users use Widnows as their OS.
When any user logs in via telnet a menu appears.
This menu allow users to do some things such as connecting to another server, print some information, etc.

I'd like to replicate this configuration in another server, but I cannot find the way to do this.

I've checked the '/etc/profile' file and the '.profile' for every user but I cannot find any reference to the telnet's behaviour.

Please point me to the right direction. Thanks for your time.

I know nothing, and many things are possible, but...

> Any user must login using a telnet client.

Does that mean that a connection made using rsh/remsh or ssh does not
lead to this menu program/script?

If it _is_ Telnet-specific, then I'd look at /etc/inetd.conf to see
what gets run when a Telnet connection is attempted.

In desperation, I might look at "ps" output to see what's running
when this menu thing is operating, and then start looking for _it_.

I would check the default shell in /etc/passwd for the users. It may be that the default shell is the menu system script rather than a real shell (like /usr/bin/sh, /usr/bin/csh, etc.).

Or that. Step one is to determine (or reveal) whether the key fact
is Telnet, or a particular set of users, or what.

Probably the menu application is a simple shell script, that is loaded through the passwd file (as said), check out it, it will pointed to the script filename...

Telnetd (configured by inted.conf on hpux) is calling an alternative login program(a script)

On linux i have this line,check for similar on your hpux server

telnet  stream  tcp     nowait  root    /usr/sbin/tcpd  in.telnetd -L /usr/local/bin/alternative.sh
