Great stuff – that has resolved that error.

Just need to get my head around what should and what should not be included/excluded now.

You would of thought there would be a “this is a good layout” for inclusions/exclusions for RHEL. Which you could start with in the knowledge you aren’t going to kill your system and then add/remove from it as you learn more.

Does anyone know of such a list ?

Cheers

While it is not recommended to scan everything under /var (or /var at all), the reason it fails is because you have /var submounts (/var/log, /var/tmp).
This is currently a known bug in clamav (I reported it: https://bugzilla.clamav.net/show_bug.cgi?id=12306 ), and the workaround in your case is:

OnAccessIncludePath /var/log

OnAccessIncludePath /var/tmp

OnAccessIncludePath /var

and then, if you don't want /var/log and /var/tmp, add these in the exclude:

ExcludePath ^/var/log
ExcludePath ^/var/tmp

Hi

 

We have a need to have OnAccessScanning on our RHEL servers but with some path exclusions.

 

So as I read the manuals etc it seems I have to use the OnAccessIncludePath rather than the OnAccessMountPath.

 

So the filesystem layout is as such :-

 

/

/boot

/home

/var

/var/log

/var/tmp

/var/log/audit

 

So I have set up the following IncludePath entries in scan.conf

 

OnAccessIncludePath /boot

OnAccessIncludePath /dev

OnAccessIncludePath /etc

OnAccessIncludePath /home

OnAccessIncludePath /opt

OnAccessIncludePath /usr

OnAccessIncludePath /var

 

When then starting the clamd:scan service all path seem to be ok apart from /var which gave the following error

 

ERROR: ScanOnAccess: Could not watch path ‘/var’, No space left on device.

 

So I increased the number in /proc/sys/fs/inotify/max_user_watches from 8192 to 32768 ( Only 21551 total directories in the whole of the server so should cover it )

 

So now it doesn’t give me the message about space but gives this message :-

 

ERROR: ScanOnAccess: Could not watch path ‘/var’, Success

 

And is still not monitoring for anything under /var ( eicar test files not being picked up. ) All other paths seem to be working ok.

 

Does anybody know where I am going wrong ?

 

Cheers

 

Ian
