Yes, already checked those (the first from OMSA docs, the second from
a google search).  Both were correct.

Yes, have all that.

Ah, cool... Thanks for that one.

Way cool!  Thanks a million.

Yea, I spent a day just getting this worked out (because yes, I'm running
a 64-bit distro, and lots of libraries were missing...)

Thanks to your help and my persistence, I now have it working...  Your
debugging tips (above) were a great help.

I actually was able to upgrade it, and I'm now running a current OMSA
(OMI-SrvAdmin-Dell-Web-LX-620-677.rhel4.tar.gz) on OpenFiler 2.3 with
the SNMP working on two (identical) machines.  Only had a few minor
issues getting the 6.2 to work...
