Problems compiling pyclamav.

linuxlover.chaitanya · 12-29-2009, 05:05 AM

Hello all,

I am trying to install clam av and then get it integrate it with squid. One way is to install dansguardian-av. But this is built on old dans version. So the other option that I have is to install pyclamav and SCAVR ( squid clam av redirector ) and use.

Downloaded pyclamav and extracted it and now trying to compile it.

Running this command

python setup.py build and getting the error:

Code:

Any ideas?

I once installed Clamav on a Ubuntu 7.10 directly from Synaptic, kubuntu must have it in their repositories.
I see that you are using a pyton script.
Did you check that the setup.py script is using the correct path for your system? also, do you change the permissions of the script?

has to be removed. You are now strongly encouraged to use pyClamd ! "

pyClamd → http://xael.org/norman/python/pyclamd/

.. I have no idea how well it works .. just referring the text ..
..... ..

But then again, pyclamd is in the repo : python-pyclamd

Yeah, there is a package for it: python-clamav.

linuxlover.chaitanya · 12-29-2009, 11:02 PM

Sorry guys. I am not using Ubuntu for my squid purposes. This is just my desktop. Server is running CentOS5.4 Final.

@knudfl: Will give that a try.

linuxlover.chaitanya · 12-30-2009, 12:50 AM

Downloaded the pyclamd and copied as said. I am using with squid clam av redirector program which is also written in python.
have changed SquidClamAVRedirector.py to reflect the changes for the use of pyclamd instead of pyclamav.
I am running it as

/usr/local/bin/SquidClamAVReidrector.py -c /etc/squid/SquidClamAVRedirector.conf to test. I just need to know if it should end or not or should it give some output.
For me it is just there and cursor is blinking forever. And I have to end it with Ctrl+D.
Is it what I need to do?

knudfl · 12-30-2009, 04:21 AM

Arh .. you are just trying to put us on the wrong track ?
OK then, CentOS 54 it is ..

Please use the "mark_alfred" link .. post # 4

I am not trying to put you on wrong track. Why would I do that. Its me who needs help.
I forgot to mention the OS of the server I am working on in the first post and did not realize that so just gave it in the next post. But then that is very much a relevant information, is not it?

Any how I got the diff but that does not work. That patch is not working.
This is the error while I try to patch

Quote:

patch < python-clamav_0.4.1-1ubuntu2.diff
can't find file to patch at input line 3
Perhaps you should have used the -p or --strip option?

linuxlover.chaitanya · 12-30-2009, 05:35 AM

Ok I got it running. I was running the patch command from the wrong location. But still I do not find it working.
/usr/local/bin/SquidClamAVReidrector.py -c /etc/squid/SquidClamAVRedirector.conf
The command just does not throw any output and cursor keeps blinking.
I am trying this for the first time and do not know if there should be any output or not.
But if I add this line to the squid, I lose all the internet.

FWIW, when I was using Squid with Clamav I don't recall needing to bind it with any Python glue? I don't recall what I used (which is really helpful - I know) but a quick scout around offers this:

http://freshmeat.net/projects/squidclamav

This works with Squidguard: http://viralator.sourceforge.net/
Untested, but after my experience with Dansguardian anything else is worth a try!

Without being rude, I would have to give Dansguardian a -1. It's great when it works, but the documentation - which you spend days following and trying to unravel, often ends up being out of date and not relevant to the version you are trying to install - it became a nightmare for me and I gave up with it.

Untangle is interesting and worth a look at too - but as a stand alone distro it's not for everyone.
Good luck and sorry that this is probably no more help than a chocolate teapot.

I did try to use it as well but when tested it gives a lot of errors.

Code:

ERROR -1 = incorrect number of scanned fields

I have dansguardian-av with me as well. But the version on which it is built is old. So it lacks some of the features from the newer version that I would like to use.
