I think it's more or less simple: for telnet / ssh, you only need to put a valid shell in /etc/passwd to enable telnet. if you want to disable it, put /bin/false or an invalid shell (the first it's my regular choice. do not forget to add /bin/false to /etc/shells if you do not have it already there) Gabriel Orozco Sysadmin SAM/IT ----- Original Message ----- From: "Gregory Dunlap" <gtdunlap () midsouth rr com> To: "security-basics" <security-basics () securityfocus com> Sent: Friday, February 27, 2004 10:55 PM Subject: restricting telnet via username
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. Thanks, Greg --------------------------------------------------------------------------
