Red Hat 9 limited to 60 telnet sessions


I'm running Red Hat 9 and I'm hitting a 60-session limit for telnet. Additional sessions just get refused. (error: "connection closed by foreign host"). I know this has to be configurable somewhere, but don't know where. Anyone know?

Thanks

You should really look into using ssh instead, more secure..

Thanks for the reply. I should have made it clearer that users are using telnet to login TO the Linux 9 system from non-Linux systems. It's Linux 9 that's denying anything over 60 connections. Otherwise I wouldn't have a problem switching to ssh.

Thanks - a friend of mine gave me the solution to this. In the xinetd.d/telnet config file, I had to add the line "instances = UNLIMITED" to allow unlimited telnet connections. The default was set to 60 in xinetd.conf. Thanks again to all who responded or spent time researching this.

No pun intended but using Windows to telnet to a Linux host thinking there is no other way is a poor excuse in my opinion when it comes to security for your system.
It's called putty, it's an ssh client for Windows to connect to ssh servers that run on *nix hosts.. download it, use it, be more secure and get rid of that plain text anyone can see my password and see what I'm doing insecure telnet..

And there's even WinSCP as well where you can not only use ssh but scp to copy files to and from Windows and Linux using ssh.
