Timeout issues

[Lewis, Aaron]

I have two identically configure Alpha ES80 servers. They have recently
been upgraded to VMS8.3 & Multinet 5.2, with all the same patches
installed on both. On 1 system any idle telnet connection gets dropped
after 1 hour, on the other system it will stay connected forever, which
is what I want. Both systems have keep alive timers set





Service "TELNET":

TCP socket (AF_INET6,SOCK_STREAM), Port 23

Socket Options = SO_KEEPALIVE

Keepalive timers: idle 900 seconds, probe interval 75, 2 probes

INIT() = Merge_Image

LISTEN() = TCP_Listen

CONNECTED() = TCP_Connected

SERVICE() = Internal_Telnet

Program = "MULTINET:LOADABLE_KERBEROS_TELNET"

Backlog = 500





. I've checked with the firewall guys and they verified that it is
nothing on their side. Anyone have any ideas on what's happening

I'd start a tcpdump, start a telnet session, let it be idle and
get dropped and see who is closing the connection and why.

$ mu tcpdump host <client-ip> and port telnet
