UNIX for Dummies Questions & Answers

Hello,
I have AIX 5.3 at home connected to netgear router. Port Forwarding has been enabled on the router. Problem is that if I want to telnet, I have to try 2 or 3 times before I can get a logon prompt. It times out for first or second time (Connection to session <IP_Address> failed: Connection timed out) but then in next attempt it will connect. If I try to open another telnet session, I have to go through the same thing again.
I dont think its settings in AIX because if I telnet from my home computer which is on the same LAN, using private IP, it connects right away. Problem happens when I use Public IP.
Any suggestions what it could be ?

Regards.

One common reason is that when the telnet server receives the connection it does a remote name lookup.

Check that the AIX box can resolve the IP address of your client machine using

Code:

nslookup ip-address
