Issue/Introduction

You want to know how to obtain and install standalone virus definitions on your Linux-based operating system (RedHat, Ubuntu, etc.), using Intelligent Updater (IU) definitions.

Resolution

1. Obtain (download and save) the Intelligent Updater from one of the following locations:

a. http://www.symantec.com/security_response/definitions/download/detail.jsp?gid=sep#secTab3
On the Unix Platforms tab, look for a filename ending in core15unix.sh (for example, 20180131-019-core15unix.sh).

b. https://definitions.symantec.com/defs/download/symantec_enterprise/index.html
Look for a filename ending in core15unix.sh (for example, 20180131-019-core15unix.sh).

c. https://definitions.symantec.com/defs/download/symantec_enterprise/static/
symcdefs-unix.sh is a statically named file that is updated with each daily release of definitions.

Note: Definition hosting has moved from FTP to Http-foldered servers. FTP will be fully discontinued on Dec 21, 2019

Note: The file download via HTTP is typically faster than FTP. The current size of the file is just under 400MB.

NOTE: Once downloaded, the .SH file needs to have Executable permissions. To accomplish this, execute the following command:
chmod +x *unix.sh
 

2. The script must be executed as root or by using sudo; if it is not, the following error will occur.

  • $ ./symcdefs-unix.sh
    Validating available tools...

    ERROR: Require write access to /opt/Symantec/virusdefs/incoming.
    There are several methods to meet this requirement.
    1. Run this script from the root user account.
    2. Add the current user as a member of the "avdefs" user
    group.
    3. chmod 777 for /opt/Symantec/virusdefs/incoming.
    We recommend either of the first two options for security reasons.


3. Uudecode and uncompress must be installed. These can usually be installed by installing the Sharutils package. In some instances, you may need to install the ncompress package as well.

Note: If you get an error referencing either utility, please run one of these commands as root or by using sudo to install them. The command to install sharutils may be different than those listed below, depending on the distribution and version of Linux being used.

  • up2date sharutils
    yum install sharutils
    apt-get install sharutils

 

  • up2date ncompress
    yum install ncompress
    apt-get install  ncompress

 


4. A successful definition installation via Intelligent Updater should result in the following output.

  • # ./symcdefs-unix.sh
    Validating available tools...
    Extracting Intelligent Updater software package...
    Checking software package for damage...
    Uncompressing software package...
    Extracting distribution files...
    Installing virus definitions to /opt/Symantec/virusdefs/incoming
    Copying definition files...
    Removing temporary files.
    Virus definitions installed successfully.
    A tran script of this installation has been saved as /var/log/iu-install.lo g

 

 

Applies To

 

Note that the unix.sh updater (32-bit) provides the appropriate updates for both 32-bit and 64-bit SEP for Linux (SEPFL) clients. Even with 64-bit Linux systems, use the file that ends with "unix.sh" not "unix64.sh"

 

Additionally if you run the Live updater tool you may be prompted to Gather Extended repositories.

**This is a 30gb repository**

In Red Hat Enterprise Linux 6 & 7, sharutils package is available through the "Server Optional" channel:
https://access.redhat.com/solutions/48627  

In RHEL8, sharutils is in the "CodeReady Linux Builder" repository:
https://access.redhat.com/articles/4348511


**This requires your Red Hat Enterprise Credentials**
