 Slow telnet and ftp Hello, I have a server that is unusable through telnet and ftp connections. If i log a the console everything is fine. If i do rlogin from another host it is slow. The server will answer from time to time but most of the time it just freeze and does not answer for several minutes. CPU is 99.5% idle, RAM used is under 5%, swap is similar.. No disks are full. "perfmeter" show minimal usage. Only context change seem a bit frequent but i am not sure if this is not normal. All i had running on this is a web server (JavaWebServer) but if i deactivate it and reboot, the behaviour is the same, slow for rlogin connections. The server is running under solaris 5.8 and has been stable for years before i got this problem. Sylvain      |

When you rlogin and get a shell prompt, what does who am i report back? If the remote host is unresolved, this will show it. Put the hostname in /etc/hosts or fix DNS. -- DeeDee, don't press that button! DeeDee! NO! Dee... |
