From: Iskander, Tim (

First off, thanks to those who responded.
The problem was really due to our network people
who installed a firewall recently which apparently
was misconfiugred (no comment).

Poor Sun SA living in a PC world :-(

Orignal message...
I have a few suns connected here as follows

 -----[cisco switch]-----

     sys2 [cisco 100baseT conc]

as of sometime today (with presumadley no changes),
rsh/telnet etc do not work from zeus to sys2!
16:37 root@zeus 10#telnet sys2
Trying 204.x.x.152...
Connected to sys2.
Escape character is '^]'.
SetSockOpt: Broken pipe
Connection closed by foreign host.

16:42 root@zeus 11#rsh sys2 ls /tmp
write: setting up stderr: Broken pipe

sys2 is IPX (also NIS master) running SunOS 4.1.3
zeus is Ultra 1 running Sol 2.5.1 with Sun 100baseT card

has anyone seen this type of strageness before? Its almost
like someone is resetting the connections right after
tey are set up.
