RE: restricting telnet via username

If the users are needing to run an application and that's it, you could use
the exec /path/to/app/application as the last line in their logon script.

HTH,

The server is the standard telnet server that comes with HPUX, the only
config I've found is in inet.d so far and that just turns it off and on
for boot.  The client is a firm ware level OS on a scan gun by
Intermic.  This is not SSH, the OS on the scan gun is quite limited and
can not run an ssh client.  If I was using ssh it would be ideal since
the AllowUser option is there.  But I'm stuck with telnet.  Any help on
how to limit the telnet daemon to a list of users or only have the
telnet server spawn off a process (the users are login in to run a app
on the server, no other shell access is needed).

Any help is appreciated,
Greg

Hello all,
  I'm attempting to restrict a telnet session of a group of users who
need to run one application on a server.  They login via telnet and that
is the only option at the moment.  They need to run a shell script and
then that will launch the app.  I've set the shell for these users to
the shell script so they won't have access to anything but this app.  I
would like to restrict the telnet daemon further to allow only certain
user names so they can't do a brute force attack.  In sshd_config I've
aways used allowd users setting but I don't see that in the hpux telnet
config.  Any help would be greatly appreciated.


which os and which app combo ?

if you are using windows then just add all the users that you want telnet
access to to TelnetUsers group and if you are using unix you will have tell
which version and which os for us ( the list ) to help you

are u using telnet or ssh ?

please post more info ...
