ClamAV again

[wolfsden3]

I'm sure there's lots of discussion about ClamAV but I have yet another question as I dig into smoothing out the rough edges on my MailCleaner installation.

On your git (https://github.com/MailCleaner/MailClea ... _clamav.sh) I see it says:

Code: Select all

echo -n " installing clamav binaries packages...";
aptitude install mc-clamav &> /dev/null

Why use "mc-clamav" instead of just using clamav? The reason I ask is if I run a freshclam:

Code: Select all

/opt/clamav/bin/freshclam --config-file=/usr/mailcleaner/etc/clamav/freshclam.conf

I get an "error" that says:

Code: Select all

ClamAV update process started at Mon Jun  4 23:18:43 2018
WARNING: Your ClamAV installation is OUTDATED!
WARNING: Local version: 0.99.2 Recommended version: 0.100.0
DON'T PANIC! Read http://www.clamav.net/documents/upgrading-clamav
main.cvd is up to date (version: 58, sigs: 4566249, f-level: 60, builder: sigmgr)
daily.cld is up to date (version: 24633, sigs: 1975810, f-level: 63, builder: neo)
bytecode.cvd is up to date (version: 319, sigs: 75, f-level: 63, builder: neo)

So...it would seem that the binary is out of date. I'm not 100% certain what the difference between 0.99.2 and 0.100.0 is but I'd like to be running the "latest" version if possible.

Is it possible to just modify that script to use clamav rather than mc-clamav...? What's special about mc-clamav?

Then regular updates to the clamav binary could be kept more up to date UNLESS you have a newer more up to date mc-clamav that can get updated via a cron or update process.

Thanks

Hello wolfsden3,
All main software package composing the MailCleaner engine are package compiled by MC Team to have control on path used (not standard paths here) and the configuration to use. They come and/or are made to work with script embedded in MailCleaner like /etc/init.d scripts.
But as you noticed it has a backdraw as these package need times to be re-tested and adapted each time a major version is out.
I have no simple solution to allow scanning with a newer version here...

Hello Florianb,

just new to MailcleanerCE I am facing the same issue. Digging a bit around it seems to me that the major problem is more to deal with the actual signatures rather than the latest clamav release.
So the situation is actually running an outdated clamav wth no longer supported/loadable signature files. As a result I am using a scanner that is not able to work (at all?).

Do you have any suggestions to overcome these problems?

Fully understanding your comments on building the MC-CE-package, I guess that there must be many users who are in the same situation?!

Thx for your answers and suggestions
Ralf

Same erro for me.

Hello,
About people with an error of mirror for clamav, you should check the folder where signatures are installed (I don't remember it to be honest)
Then you can remove at least tmp folders and a file called mirror.dat if i remember correctly.
After this try to re-update by using the same command than MailCleaner (specifying the freshclam.conf), it should do the trick.

Hi Florian,

Thanks for the reply!
i am not really used to cli or ssh so it sounds like a good plan but i have no idea about the commands to get there
can you please write in detail how i can get to the temp file, delete it and then update the freshclam.conf or can i just update everything with updater4mc.sh or apt-get update && apt-get upgrade

thanks! learning a lot lately lol

Hello,
Sadly I don't remember exact path and I don't have MC to test it but I suppose (hope) someone using it could copy exact path and filename.
Globally here:
login to the shell, then:

Code: Select all

cd /var/mailcleaner/spool/clamav
rm -rf mirror.dat
/usr/mailcleaner/etc/init.d/clamd restart

Hope it will help !
