Question Telnet Settings


How many concurrent connections can the default xinetd configuration for telnet support? What changes would I have to make in order to raise that number. I currently have a machine that freezes on users and will not accept anymore connections after 6-8 users. The machine is somewhat new (933mhz) and has 256MB of RAM. Would it make a difference that most of my users are logging in as the same user? Help? Thanks.

Look under /etc/xinetd.conf
instances=...
P.S. And telnet is DANGEROUS !!! SSH is the way to GO!!! http://www.openssh.org and windows client is available at http://www.chiark.greenend.org.uk/~sgtatham/putty/

I see, it is set to 60 by default. Is there any parameter for time out? I've been getting a lot of grief over this telnet issue. I agree that SSH is the way to go, but the server is behind a firewall. Which brings up a new issue. We currently have a Checkpoint firewall that our users VPN to via SecureRemote, and then telnet to the internal address. It's strange I can telnet into the other servers fine, but once this particular box gets more than like 6-8 (same username) connections I start getting complaints about it hanging or not allowing connections (timing out). However I can still telnet to it from within the network. Would it be safe to say it is a VPN, firewall issue? Is there any other parameter that may be causing this error. Thanks!

Even though you are behind a firewall, somebody within your network maybe running a sniffer (snort for instance http://www.snort.org ) everything sent through a telnet session is sent in the clear (user names, passwords, commands, etc) As for timing out it might be VPN relative issue, somebody who masters networking section might help you wiht that, I must admit I am not strong in networking issues, but I am learning fast .
