Pete;

Yesterday I had very similar difficulties at a client. Differences are this is P6, HMC console, and LPARs but I don't think that's a factor since you were able to get in with the LAN console. Routing on this box is correct, although that could be a problem for you as well. We just restarted the telnet server and it started working without having to recreate anything. We have experienced similar problems with the SMTP server as well. I'm starting to wonder if there is a fault somewhere deep in TCP. We have a PMR open and are working it actively however every time we try to trace it, we do not see a failure.

We were planning on getting all the most recent PTFs/Groups etc hoping there was a problem that was fixed but it seems you have debunked that theory. That system is not that far back in PTFs anyway but it never hurts to hope...

In the mean time try a telnet server restart. Have you tried NETSTAT to see if the route is valid?

Got a brand spanking new 720 up and running. Initially I had the
operations console connected, I configured an Ethernet line and
connected via telnet (5250). I also connected via IBM i navigator. I
even FTP'd a file from the old iSeries over to the new 720 (both running
IBM i 7.1) All seemed well. I disconnected the telnet session after
signing off. Ended the navigator session and moved on to other things.
I went back to check on something but the 5250 session wouldn't
connect. So I started ops console and check for errors and saw none.
After playing around with various settings, routings, and decided to
completely retrace my steps. I deleted the all the configuration
objects. Started from scratch.

I created new Ethernet line description, added the interface, added the
default route, varied on the line, started the interface and then
started the telnet server. Still, no joy. I downloaded the TCP/IP
group PTF and applied it. No change.

The first time I connected with telnet, a new virtual device description
was created. I deleted it to see if it would be recreated. It has
not. So I am not sure just where the issue is. I can ping the default
gateway but I can't reach any other device on the subnet.

I'm stumped. It seems like a routing issue but......

I*think* I saw something similar recently on this list but the archives
are offline at the moment. Any ideas where to look next?
