Squid and *.rpm caching.

English Network/Internet
1

Hello all.
I have a network with openSuSE 11.0 workstations, which are connected to router with Squid. Iptables is redirecting all traffic to squid transparently. Some of the workstations are updated rarely, some often. I noticed, that rpms from repos are cached, but almost always Squid MISS them, because of different source mirror. This makes cache grow useless when the same rpms are downloaded by different stations. I’ve found python redirector named IntelligentMirror from Fedora, but Squid can’t start with it, and tells me:

ImportError: No module named rpmUtils.transaction

All required packages are installed (python-urlgrabber, python-iniparse, rpm-python)

Is there any other way, best would be in Squid itself, to make Squid cache and HIT rpms?

Not the best solution but you can change download.opensuse.org to a specific close mirror on all the pc’s so the information can be found by squid…a simpler solution might be to redirect to a specific mirror using squirm in squid.

I also needed to install yum and, for my distro, in /etc/squid/intelligentmirror/config.py add (just before “import os”) :


import sys
sys.path.append('/usr/share/pyshared')
