Wow. I've been using rsync for many, many years to backup my system. Just this past weekend, after having to restore my /home filesystem from one of my two backup drives (they alternate living...
With this problem out of the way, I've summarized the situation & my solution in this post on my Prairie Rim Tech blog:
http://tech.PrairieRim.com/2013/01/snmp-dns-dhcp-and-ubuntu-1210.html
Wow, what a rabbit trail. In the interest of redundancy, my DHCP server was handing out the IP's of 3 different DNS serves--itself plus two at my upstream ISP (both of which act as secondaries for...
Oops. Not always. In finally saw them return the wrong (external) IP for yavin... once. Then back to the correct (internal) IP again. I guess the problem is not SNMP-specific.
OK, it's getting weirder. I mentioned that yavin (the RHEL box, and destination for these SNMP queries) is my firewall as well as my DNS & DHCP server. DNS is set to reply with the internal LAN IP...
Curiouser and curiouser. The RHEL box (yavin) is my network firewall. The tcpdump inspired me to check the iptables logs, and it appears that every time SNMP fails, I also get a log entry saying...
OK, I ran tcpdump on both servers, and both showed the same results. Here's the first couple queries from a good run:

I have an old RHEL3 box on my network which I monitor via SNMP from my Ubuntu server running MRTG. I've been doing this for years with continually-updated versions of 32-bit Ubuntu, and have never...
<sigh>
It looks like the 64-bit extensions didn't appear in net-snmp until v5.5, which was released in July 2012. The most recent version is 5.7.

I'm running a fresh 64-bit install of 12.10. It's the desktop edition, but I do run some server apps on the box, including SNMP.
I'm trying to use mrtg & net-snmp to monitor (among other things)...
I'm running 32-bit Ubuntu 10.10 desktop on 64-bit hardware. Is it possible to do an in-place upgrade to the 64-bit version? My system disk has had lots of custom software installed over the last...
Fortunately, Rosewill is neither unresponsive nor clueless. They answered my email queries in just a couple hours. Unfortunately, my old RX35-AT-SC enclosures (I have two) are not compatible with...
If I'm reading correctly, most of the discussion thus far pertains to booting off a 3TB drive when that's the only disk on your system. I'm running 32-bit U10.10 and booting off a nice, safe, small...
I've been running phpbb2 (stock package) in Ubuntu for a couple years now, starting with 7.04. I recently upgraded from 9.04 to 9.10, and with that came the forced upgrade to phpbb3, since phpbb2...
