Restrice telnet access

[Alan Casey]

Does anyone know the best way to restrice telnet access so that a particular user can not use telnet, but still has a regular login shell?

Hi


See man inetd.sec

All internet services controlled by inetd (includes telnet and rlogin)
have their access controlled by
/var/adm/inetd.sec.

Hi,
I did not understand your question.
For logging in without telnet you can use rlogin . But you client machine should have rlogin client.

Alan,

Are you trying to restrict them from telnet'ing into the machine or out from the machine?

Hi Pete,

Am trying to restrict them telnetting to the machine. The users must have a full shell for ssh connections.

Hi,

you can restrict that in
/var/adm/inetd.sec

Another thing to look at,
/etc/inetd.conf starts the telnet process. You can simply comment it out.


Or - still another
We use scripts and the /etc/nologin file to restrict users on our servers, for this process.

You can look at the users ID of GID to determine whether you want them to be allowed access.
