I execute a snmpwalk on my ubuntu boxes from my main slackware server (14.2) and I can see the deb packages listed under OID .1.3.6.1.2.1.25.6. I execute a snmbwalk to any of my slackware boxes from my main slackware server and I receive the error: "hrSWInstalledTable produces No Such Object available on this agent at this OID"

I do see all the other HOST-RESOURCES-MIB items (.1.3.6.1.2.1.25.1 through .1.3.6.1.2.1.25.5 ) -- for example my running processes (hrSWRun) and devices and storage (hrDevice, hrStorage) so it seems the proper MIB is loaded but for some reason it doesn't know who to read the hrSWInstalledTable at .1.3.6.1.2.1.25.6


Any ideas how I can get the slackware installed packages list via snmp on slackware?

Thanks

You'll have to write or find an extension which reads /var/log/packages and provides the information formatted correctly when those OIDs are requested by the agent.

EDIT: See https://vincent.bernat.im/en/blog/20...ending-netsnmp or http://net-snmp.sourceforge.net/wiki..._shell_scripts for ideas.

Thank you sir. Since Ubuntu appears to already have an extension, I'll first take that avenue and see if I can find the Deb package version extension and modify it for Slackware as opposed to starting off from scratch. My search so far for a Slackware extension that has already been written to build the hrSWInstalledTable has been fruitless. Worst case, I'll take the information from the links provided and write one from scratch.

Also I'm beginning to wonder if it would be easier to just write a bash script to gather all the installed packages for all the systems outside of snmp and just import it into the NMS or use another tool all together even for that matter.

Assuming snmp would be easiest as it is gathering everything else already, but bash scripts would allow me to gather system health related information and configuration data separately.

I don't post here often and not sure of the rules here, aS far as marking this solved, should I go ahead and mark it solved as it requires custom code to resolve this, or should I wait until I actually either decide to scrap the idea in favor of pure bash scripting to get the information into a common place for all systems, or actually find/code a snmp extension that builds the Slackware hrSWInstalledTable?

Thanks,

Robert

Well, I would strongly suspect that any Debian package version extension will use calls to dpkg or some such to get that information. Slackware doesn't have much of an equivalent (it might, but I've always just looked in /var/log/packages), so I don't think such a thing will help all that much.

As for marking the thread SOLVED, if you think the problem you have has been solved (or as solved as it's going to get), then mark the thread so. If you think that you'll be back to ask further questions, then maybe let it be.

* Sorry for the extra late reply, this is for the benefit of anyone still looking for an answer.
* As installed, net-snmp reports installed OS packages from /var/cache/hrmib (vs. Slackware /var/log/packages, /var/lib/pkgtools/packages).
* Method: clear out /var/cache/hrmib (disused by Slackware). Then, for each file in /var/log/packages, create a similarly-named empty file with timestamp matching the original.
* I use this script after each update of my Slackware 14, 15, and -current systems:

#!/bin/bash
cd /var/cache/hrmib || exit 1
find . -type f | xargs --no-run-if-empty rm
for i in /var/log/packages/* ; do
j=$(basename $i)
d=$(ls --full-time $i | awk '{print $6 " " $7 " " $8;}')
touch --date="$d" "$j"
done


* Now I get this result:

HOST-RESOURCES-MIB::hrSWInstalledIndex.1 = INTEGER: 1
HOST-RESOURCES-MIB::hrSWInstalledIndex.2 = INTEGER: 2
HOST-RESOURCES-MIB::hrSWInstalledIndex.3 = INTEGER: 3
HOST-RESOURCES-MIB::hrSWInstalledIndex.4 = INTEGER: 4
HOST-RESOURCES-MIB::hrSWInstalledIndex.5 = INTEGER: 5
