Sophos Anti-Virus for Linux 9 Startup Guide
Sophos Anti-Virus for Linux 9 detects and deals with viruses (including worms and Trojans). It can detect all Linux viruses and all non-Linux viruses that might be stored on your Linux computer and transferred to non-Linux computers. It does this by scanning your computer. On-access scanning is your main form of protection against viruses. Whenever you open, save or copy a file, Sophos Anti-Virus scans it and grants access to it only if it is safe. Sophos Anti-Virus also enables you to run an on-demand scan to provide additional protection. An on-demand scan is a scan that you initiate.

Sophos Anti-Virus for Linux
1 Is this the right guide?
There are three different types of Sophos Anti-Virus for Linux installation.
Before you start, read about them here and make sure you’re reading the right startup guide.
Unmanaged installations
In this type of installation, Sophos Anti-Virus for Linux is installed on standalone or networked Linux computers, but is not configured or managed centrally.
For this type of installation, continue reading this guide.
Note
We recommend that you use managed Sophos Anti-Virus for Linux instead.
Installations managed by Sophos Central
You can install Sophos Anti-Virus for Linux, or upgrade an existing installation, so that it is managed by Sophos Central.
For this type of installation, sign in to Sophos Central, go to the Protect Devices tab and follow the instructions for Linux there.
Note
If you don't have Sophos Central yet, you'll need to get an account.
Note
If you are using 64-bit Linux servers managed through Sophos Central see the Sophos Anti-Virus for Linux 10 startup guide .
Installations managed by Sophos Enterprise Console
You can install Sophos Anti-Virus for Linux so that it is managed by Sophos Enterprise Console. See the Sophos Enterprise Console startup guide for Linux and UNIX .
Note
If you don't have Sophos Enterprise Console yet, you'll need to install it on a Windows server and do some basic setup.

2 About Sophos Anti-Virus for Linux
2.1 What Sophos Anti-Virus for Linux does
Sophos Anti-Virus for Linux detects and deals with viruses (including worms and Trojans) on your
Linux computer. As well as being able to detect all Linux viruses, it can also detect all non-Linux viruses that might be stored on your Linux computer and transferred to non-Linux computers. It does this by scanning your computer.
2.2 How Sophos Anti-Virus protects your computer
On-access scanning is your main form of protection against viruses. Whenever you open, save or copy a file, Sophos Anti-Virus scans it and grants access to it only if it is safe.
Sophos Anti-Virus also enables you to run an on-demand scan to provide additional protection. An on-demand scan is a scan that you initiate. You can scan anything from a single file to everything on your computer that you have permission to read. You can either manually run an on-demand scan or schedule it to run unattended.
You can find details of all configuration options in the man pages and the Sophos Anti-Virus for Linux configuration guide .

4 Install Sophos Anti-Virus for Linux across a network
You install Sophos Anti-Virus for Linux on networked Linux computers as follows:
1. Create a central installation directory (CID) on a server. This is a set of files that includes everything needed for installation.
2. Install Sophos Anti-Virus for Linux across the network from the CID.
4.1 Create the CID on the server
To perform this procedure, you must be logged on to your Linux server as root.
1. Log in to http://www.sophos.com/en-us/support/downloads.aspx
with your Sophos ID.
2. If you have logged in for downloads before, you see the Product Downloads and Updates page.
Note
If this is your first time, you see your profile. Click Endpoint and Server Protection and then
Downloads and Updates.
3. Under Standalone Installers, click the link for Anti-Virus for Linux.
4. On the web page that is displayed, download the Sophos Anti-Virus for Linux tarball to a temporary directory, for example /tmp .
5. Change to the temporary directory and untar the tarball: tar -xzvf tarball .
6. Run the install script: ./sophos-av/install.sh
.
Note
For information about configuring Sophos Live Protection methods during the installation, see
Turn Sophos Live Protection on or off
(page 12).
When prompted for the type of auto-update you require, select Sophos . Enter the username and password that are included with your license.
Sophos Anti-Virus for Linux is installed in the directory that you selected.
7. Run the update script to download the central installation files from Sophos: /opt/sophos-av/ bin/savupdate .
Attention
By default, Sophos Anti-Virus for Linux downloads the required Talpa Binary Packs to enable on-access support on the current system. This can be a problem if the system is acting as an update source for Sophos Anti-Virus for Linux clients on other kernels/distributions.
a) If you intend to use the client as an update source for other endpoints then run the update script /opt/sophos-av/bin/savupdate with the following option set
PrimaryUpdateAllDistros TRUE .
This downloads all the Talpa Binary Packs available.
Copyright © Sophos Limited
Sophos Anti-Virus for Linux
A local cache directory is created by default in /opt/sophos-av/update/cache/Primary/ .
The local cache directory is the installset that is used to update an installation of Sophos Anti-
Virus for Linux. The local cache directory updates itself automatically from Sophos. By default, it updates every 60 minutes, provided that the server is connected to the internet.
8. Copy the local cache directory to a location that is accessible by all the other computers on the network to create a CID.
We recommend that the other computers have only read access to the CID.
You have finished creating the CID on the server. Make sure the CID is updated from the local cache directory regularly.
4.2 Install Sophos Anti-Virus from the CID
Having created the CID, you install Sophos Anti-Virus on the rest of the network as follows:
1. Create a deployment package that can be used to install Sophos Anti-Virus on other computers.
2. Install Sophos Anti-Virus on each computer using the deployment package.
4.2.1 Create a deployment package
To perform this procedure, you must be logged on to your Linux server as root.
You can use the mkinstpkg script to create a deployment package for your end-users. This script uses the same display as the install script, and the answers gathered are inserted into the deployment package. When the end-user installs from the deployment package, it does not ask them any questions and sets up both the update location and credentials for them correctly. You can create a package in tar, RPM or deb format.
Note
The instructions here show how to specify the package format. For details of other options you can use, see
Appendix: Command-line options for mkinstpkg
(page 13).
To create a deployment package:
1. Go to the directory /opt/sophos-av/update/ .
2. To create a package in the current directory, do one of the following:
• To create a tar format deployment package, called savinstpkg.tgz
, type: ./mkinstpkg .
• To create an RPM format deployment package, called savinstpkg-0.0-1.i586.rpm
, type: ./mkinstpkg -r .
Note
The filename might be slightly different depending on the RPM setup.
• To create a deb format deployment package called savinstpkg.deb
, type: ./mkinstpkg -
D .
When prompted for the location from which to update, type the address of the CID as it appears to the other computers. Enter the username and password that are required to access that address, if applicable.
Copyright © Sophos Limited 5
Sophos Anti-Virus for Linux
A deployment package is created in the format that you specified.
3. Use your own tools to copy this package to the computers where you want to install Sophos Anti-
Virus for Linux.
4.2.2 Install Sophos Anti-Virus for Linux using the deployment package
To perform this procedure, you must be logged on to the computer as root.
On each computer:
1. Place the deployment package in a temporary directory and change to that directory.
2. Do one of the following:
• To install from the tar package, type: tar -zxvf savinstpkg.tgz ./sophos-av/ install.sh
.
• To install from the RPM package, type: rpm -i RPM package .
• To install from the deb package, type: dpkg -i deb package .
This copies the necessary files from the server and installs Sophos Anti-Virus for Linux.
You have finished installing Sophos Anti-Virus for Linux on this computer. Sophos Anti-Virus updates itself automatically from the CID. By default, it does this every 60 minutes.
Sophos Anti-Virus for Linux also sends product and platform information to Sophos to help us with product development. See Sophos Knowledgebase Article 121214 .

6 On-access scanning
On-access scanning is your main form of protection against viruses. Whenever you open, save or copy a file, Sophos Anti-Virus scans it and grants access to it only if it is safe.
By default, on-access scanning is active. If you want, you can check that it is active and start it if necessary.
Note
To use the commands in this section, you must be logged on to the computer as root.
This document assumes that you have installed Sophos Anti-Virus for Linux in the default location,
/opt/sophos-av . If you have not, when you run a command, you must substitute the installation directory that you are using.
6.1 Start on-access scanning
To start on-access scanning, do one of the following:
• Type: /opt/sophos-av/bin/savdctl enable .
• Use the appropriate tool to start the installed service sav-protect. For example, type: /etc/ init.d/sav-protect start or service sav-protect start .

Sophos Anti-Virus for Linux
7 Run an on-demand scan of the computer
We recommend that you scan the whole computer for viruses right after you install Sophos Anti-
Virus. To do this, you run an on-demand scan.
Note
This is especially important if the computer is a server and you want to minimize the risk of spreading viruses to other computers.
• To run an on-demand scan of the computer, type: savscan / .
Copyright © Sophos Limited 9
Sophos Anti-Virus for Linux
8 What happens if viruses are detected
Regardless of whether viruses are detected by on-access scanning or an on-demand scan, by default Sophos Anti-Virus for Linux:
• Logs the event in syslog and the Sophos Anti-Virus for Linux log.
• Sends an email alert to root@localhost.
Sophos Anti-Virus for Linux also displays alerts according to whether the viruses were detected by on-access scanning or an on-demand scan, as explained below.
On-access scanning
If on-access scanning detects a virus, Sophos Anti-Virus for Linux denies access to the file and by default displays a desktop pop-up alert.
If the desktop pop-up alert can't be displayed, a command-line alert is displayed instead.
For information about cleaning up viruses, see the Sophos Anti-Virus for Linux configuration guide .
On-demand scans
If an on-demand scan detects a virus, by default Sophos Anti-Virus for Linux displays a commandline alert. It reports the virus on the line which starts with >>> followed by either Virus or Virus
