From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt) Description of problem: rlogin to an aix system works 1 time, after logging out and logging in again with rlogin it hangs. After a very long time it works again. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.rlogin 192.9.200.23 -l johan 2.exit 3.rlogin 192.9.200.23 -l johan Actual Results: hangs in step 3 Additional info: with netstat I found : rlogin client on redhat uses the first time socket port 1023, after logging out and logging in again with rlogin to the same system, it uses again socket port 1023 but hangs. Netstat gives as status on the port SYN_SENT. Rlogin in another shell while the above connection hangs, works again 1 time, this time with socket port 1022. After logging out and logging in again, hangs again on socket port 1022, netstat gives again SYN_SENT. To resume : a recently used socket port to a certain system can't be used anymore for a long amount of time to the same system. It can well be used to another system. For example : rlogin 192.9.200.23 -l johan it works (netstat shows socket port 1023 is used) ctrl-D to logout rlogin 192.9.200.22 -l johan it works, (netstat shows socket port 1023 is used again) rlogin 192.9.200.23 would have hanged ctrl-D to logout rlogin again to 192.9.200.23 or 192.9.200.22 hangs now. netstat gives SYN_SENT on port 1023
The "rlogin" use privileged ports (512-1023). The number of this ports are limited and after terminated connection is some timeout when the connection on port is in the TIME_WAIT state. I think your AIX server hasn't free ports for new connection and you need to wait for TIME_WAIT timeout from previous connection. I think you can found something interesting in the server logs. I have no idea where AIX has logs, but at linux it's in the file /var/log/messages.
