If you originally used the *nix Message Sniffer installation tarball available at armresearch.com when you first installed Message Sniffer on your Unix platform, you can use the following procedure to upgrade Message Sniffer as new releases become available. Be sure to create a backup of your current Message Sniffer installation. The upgrade procedure below should not over-write your current configuration, however, best practice is that you always create a backup before an upgrade.

1.) Download the latest *nix distribution from armresearch.com to your server. You can do this by connecting to your Unix server via SSH and running the following command, as root, from the bash: wget https://armresearch.com/message-sniffer/download/snf-server-x.x.x.tar.gz. You will need to change the x's to the version of Sniffer that you are downloading. If you are not sure which version that is, click here and you will be directed to Arm Research's downloads page. Once there, right click on the "Download *nix Distribution" button and choose Copy Link Location. You can then simply paste it into your command line after the wget command.

2.) Once downloaded, extract the tarball with the following command: tar xvzf
 snf-server-x.x.x.tar.gz

3.) Once extracted, cd to the source directory. In this example, the command would be as follows:
cd snf-server-x.x.x

4.) Run the configure script. See the section of the INSTALL notes on OS-specific issues for the options to specify for your Unix distro. The INSTALL notes are located in the source directory that you created in step 2.

5.) After the configure script is finished running, type 'make' (without the quotes) on the command line. This will build the package.

6.) Stop the snf-server service using the stop service command that is used for your Unix distro.

6.) Still in the source directory, type 'make install' (without the quotes) on the command line.  This installs the package in the default directories.

7.) Start the snf-server service using the start service command that is used for your Unix distro.

8.) To verify that the upgrade was successful, cd to the directory where SNFClient is installed and run the following command: SNFClient - status.second. This will show you the version that you are running and the date it was installed.
