Re: Weird Telnet Problem

["Paul Tykodi" <paul@xxxxxxxxxxxxxxxx>]

Dear Andrei,
If your problem is not related to a network address conflict as someone
already mentioned, it could be a memory leak in the Telnet server running on
the machine where you can see the problem. The latest OS/400 PTF for the
Telnet server on V4R3 is SF60463. Frequently the Telnet TCP/IP PTF's are not
included on a CUME tape so you should check and see whether you have this
particular PTF installed.
Good Luck!

Subject: Wierd Telnet problem

Hi all

Take a look at the strange behavior on one of our AS/400 systems today.

We have 3 systems on-site, all V4R3 and the same CUME (not the last). Every
system has 2 Ethernet cards. On the main production box only, the telnet
connection is dropping since this morning.

TCP/IP on the system is on. PING & FTP are working. The TELNET is started
(we even ended and started it twice and OPNAV sees it started). But
Microsoft TELNET is failing every time. Our sessions (Client Access & Client
Express) are connecting extremely slowly. More of that, CWBPING is crashing
on the TELNET service ... but sometimes it works!

I don't have any trace on the system; the QHST, QSYSOPR MEGQ and QTCP MSGQ
are clean. On the PC side, the CA logs keep pointing me to the CWBC01003
error (10060 returned) as if the name resolution is not done.

But this is OK, a DHCP server which works fine for all our servers and
AS/400 makes it. Otherwise the connection would have ALWAYS failed, not only
SOMETIMES. And, it's happening only on ONE system of three, after years of
stability.

I did a checklist and verified all things related to IP, IP servers, CA host
servers, host files and so on. Still, it fails. And weird, all neighboring
systems are well and fine.





Some ideas?



Thx
