The following sections are covered:

Applies to the following Sophos products and versions

Sophos Anti-Virus for Unix

Ensure that the environment variables in your login script or profile include the directories that Sophos Anti-Virus uses.

  • PATH should include /usr/local/bin
  • MANPATH should include /usr/local/man
  • LD_LIBRARY_PATH should include /usr/local/lib.

In AIX, the library environment variable is LIBPATH and in HPUX it is SHLIB_PATH.

On some systems, such as FreeBSD and Linux, you can enable Sophos Anti-Virus to use the Sophos Anti-Virus shared libraries by running ldconfig. This may require editing of /etc/ld.so.conf.

Adding environment variables

If any of the above variables are not included, add them to the environment variable(s) as shown in the examples below. Do not alter any of the existing settings.

If you are running the sh, ksh or bsh shell, enter:

PATH=$PATH:/usr/local/bin

export PATH

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

export LD_LIBRARY_PATH

If you are running the csh or tsh shell, enter:

setenv PATH [values]:/usr/local/bin

setenv LD_LIBRARY_PATH [values]:/usr/local/lib

Where, [values] are the existing settings.

You should make these variables system-wide. To do this, amend /etc/login or /etc/profile.

Note: If you do not have a login script, you will need to reset these values every time you restart the server.
