Have an AIX box at a customer site. I was trying to use it's IP address to telnet into it but failed all the time. I'm using a pc running window 2k.

Tracert and ping to this AIX box works fine and I was told customer also has extra delay telneting into the box from their end (but they succeed).

The resolv.conf configured and default gateway correct. What else should I check?

thanks

When you telnet to a host, that host does a reverse name lookup.

The easiest solution is to include your host and its IP address in the /etc/hosts file on the target machine. When you telnet to that machine it will know the IP address of your local machine, and the login prompt will be displayed in a few seconds.

The other option is to look at the setup of the DNS server the resolv.conf points to to ensure that it allows for the appropriate reverse name lookup

Hope this helps

Didn't know if you had seen this from the first question.

Check to see if there's a second firewall involved. We had opened our fw up for a vendor who could also ping and tracert, but a second fw closer to the "outside" had telnet blocked. We hadto put in a special request to open it up so the vendor could get to our DMZ.
