Hey,

I have upgraded 3 servers from SSH Tectia 4.0.3 to SSH Tectia 6.0.2. 2 of them are working fine but one server suddenly began to have troubles after about 2 hours. Now it is impossible to login to this server using SSH and even telnet. When SSH is running on this particular server, the CPU of the server is at it's maximum because of the SSH processes, which is not the case on the other 2 servers. Currently I have shut down the SSH processes on the server.

Then, when I try to make a connection using telnet it immediatly replies: 'Connection closed'. The strange fact however is that telnet refuses a connection done by the root user, but if I try it using another user, telnet works fine. (SSH doen't work in either case though) Restarting and even reinstalling SSH also didn't work. After SSH was uninstalled I tried another telnet connection but still it didn't work.

I've checked /etc/security/user, because of the telnet/root problem, but everything looks identical to the configuration of the other 2 servers. Can anyone help me with this problem?

Thank you
