ClamSup default install
Question asked by Eric Tykwinski - 9/9/2016 at 11:09 AM

We just had a Lockey macro get through, or at least I think it is.
I tested the same email through a linux box I also run which was caught from SaneSecurity's Malware db.
Linux Box shows: A virus found: Sanesecurity.Malware.26311.JsHeur.UNOFFICIAL FOUND
I'm seeing ClamSup.bat on SmarterMail download the same definitions, so is there anything special to enable them?

Hi Eric.  Check your Delivery logs for any ClamAV errors.  They would look like:
Unable to run Clam virus checks: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it 127.0.0.1:3310
If you see these, then make sure you have the Microsoft C++ 2010 Redistributable Packages installed.

What is the next step if I am still seeing those errors and both of the VS C++2010 redistributable packages are installed? I also have VS C++2005 packages installed, could they need removal?

@CCC @Rod  We reinstalled VS C++ 2010 Update 1, but didn't have an effect.  Is there any other tweaks you can think of? (StreamMinPort,StreamMaxPort, et al?)  I setup another Linux VM running ClamAV and stopped getting the errors, but I think I need to tweak the settings as the queue was growing rather quickly.  I saw you have default at 100 MaxThreads and MaxQueue to 200, same for a remote server?
 
PS.  We were receiving those errors, so I'm under the assumption that it might be a Windows TCP/IP stack issue on localhost?

Just a quick follow-up, post trouble ticket.  We had Rod remote into our server and he quickly noticed that we only installed VC++ 64bit.  Apparently both 32 bit and 64 bit are needed.  So from 50K failures yesterday on ClamAV to currently sitting at 9 failures.  I think we solved the issue.  Thanks Rod...

Does anyone know if SmarterMail calls the "ClamSup.bat" file while updating the main ClamAV system via freshclam?
 
I had the same problem mentioned above but while manually running the ClamSup.bat update process.  I had already installed the 64bit version of the Microsoft library to get ClamAV working at all on a NEW install of SmarterMail.  
 
I installed it on a new Windows 2008 R2 server that I was preparing to migrate my SmarterMail install over to.  
****Note that I used the latest installer of version 15.5.6222***  so there may be a problem with the installer?  I didn't see the library listed in the documentation for system requirements...so I am guessing that something got missed in the installer build?  I did not see any errors when installing the product.

Micky,

My issue was I didn't have 32-bit installed as well. More of a ClamAV requirement, but necessary for it to work. I can't tell you about timings right now, as I'm having a different issue, but I think they usually run in sequence.
