Hi team , We are runnig a system on CentOS 4.5 where we use a testing ERP system. Users have to login to it with telnet. When it reches about 60 telnet users, the remaing users will NOT be able to login. Hardware is , HP Pentium 4 Server with 4 Gb RAM . Pls Note we used the same system on a lower Machine with Redhat EL 3 until yesterday. But , it worked fine. @ that time, more than 100 users logined with telnet. Now, only it gves such error even when we have better Hardware and Software. Any ideas? -- Thank you Indunil Jayasooriya

What does /var/log/messages say when additional users attempt to log in?

On CentOS and RHEL, telnet is launched by xinetd and is governed by the instances limit in the /etc/xinetd.conf file. Change the limit and use "service xinetd reload" to reload the config file.
