Sorry to be thick if I've got this all confused...
Seems to me that what should happen is that the client
successfully determines the IP address of the server by looking at the
hosts file (there is no local DNS).
the hosts file looks like this:
127.0.0.1	bwlnote	localhost.localdomain localhost
...
192.168.0.6	strange.langhorst.com strange

So why would the client be trying to reach a server at 127.0.0.1 when it
knows that strange is the server and that its address is 192.168.0.6?  

Maybe you had the "it" referring to the server trying to attach to the
volume.  If so why would it be looking up itself? Does it do a remote
procedure call on itself? I guess that would make some sense if it can't
tell whether or not it is the hosting server for the volume in
question.  I guess I'm going to have to break out the source here...

Incidentally, I've added bwlnote to strange's(server's) hosts file so it
can resolve 192.168.0.3now. This does produce one interesting new
behavior (I think we're getting to the root of the problem).  I now get

from the console log before venus gets Killed.
The server's CPU utilization goes way up during this period 

Since it can' get the root volume name I looked the
/vice/vol subdir but both files there
BigVolumeList
P/vicepa Hstrange T3d3c3e F3d151e
WLanghorstHomeCoda.root.0 I1000001 H1 P/vicepa m0 M0 U2 W1000001
C397b75c0 D397b75c0 B0 A0
VRList
LanghorstHomeCoda.root 7f000000 1 1000001 0 0 0 0 0 0 0 E0000100
the remote/ directory contains a strange.list which is identical to the
BigVolumeList

The server logs look identical all that I can tell has changed is the
addition of the error messages giving me info on the failure to find
Volume name.

I saw Gus Scheidt's post about having trouble with RH6.2
I wonder if anyone else is successful in running a coda server on
RH6.2?  

Many thanks for your quick responses! We'll get this straightened out.
