SUMMARY of showfh RPC time out problem

From: Ken Hammer (
Date: Tue Oct 26 1993 - 21:43:03 CDT

I am sorry for the delay in my summary, put my mail-server was down for
a few days, and then I went down for a few days (nasty flu bug).

Anyway, I was able to fix my showfh RPC timed out " error by installing
the Sun patch 100371-02 on the IPX that is running 4.1.2. Apparently, this
is a know bug on systems running 4.1.1 and 4.1.2, but is fixed in 4.1.3.

the patch can be found via anon ftp at: ( in /pub/sun-info/sun-fixes

(as pointed out by the FAQ).

Thanks to all who responded.
