Updating ClamAV on FOG Server

As a system administrator, ensuring that your antivirus software is updated regularly is crucial to maintaining network security. In this article, we'll explore how to update ClamAV on FOG (Free and Open-Source GPL Bootable Environment) servers.

The first step in updating ClamAV is to increase the ram disk size from 50MB to 100MB. To do this, navigate to the `fog.av` file located in the `/tftpboot/fog/images/initmount/bin/` directory using the command `$sudo vi /tftpboot/fog/images/initmount/bin/fog.av`. Update the file by adding 'DatabaseMirror MyFogServerNameOrIP' and 'ScriptedUpdates off'.

Next, copy the necessary files from the `clamav0.97.7.zip` file to the `/usr/share/clamav/` directory. You can do this using the following commands:

```

$ln -s libclamav.so.6.1.16 libclamav.so.6

$cd /tftpboot/fog/images/initmount/usr/lib

$sudo cp fog.av /tftpboot/fog/images/initmount/bin

$sudo cp libclamav.so.6.1.16 /tftpboot/fog/images/initmount/usr/lib

$sudo cp freshclam /tftpboot/fog/images/initmount/usr/bin

$sudo cp clamscan /tftpboot/fog/images/initmount/usr/bin

$sudo cp clamdscan /tftpboot/fog/images/initmount/usr/bin

$sudo cp clamconf /tftpboot/fog/images/initmount/usr/bin

$sudo cp clambc /tftpboot/fog/images/initmount/usr/bin

$sudo cp clamav-config /tftpboot/fog/images/initmount/usr/bin

```

After copying the files, update your definitions by running `freshclam`. This will download the latest virus definitions from the ClamAV database.

It's also important to note that scripted updates should be disabled on the FOG server. To do this, add 'ScriptedUpdates off' to the `/etc/clamd.conf` file.

Finally, extract the contents of the `clamav0.97.7.zip` file and copy them to the `/usr/share/clamav/` directory.

By following these steps, you'll be able to update ClamAV on your FOG server and ensure that your network is protected from malware and other threats.

Sudo apt get update clamav
