Linux Agent Deployment

Download the appropriate package for your distribution, there are RPM, DEB and a tarball available.

1. Install the package
   rpm -i *path to RPM you downloaded*
   OR
   dpkg -i *path to DEB you downloaded*
2. Start and enable the service
   systemctl start quasarscan
   systemctl enable quasarscan
   Note: RPM packages earlier than 6.9 may require the libxcrypt-compat library to be installed if you see the below:
   Error loading Python lib '/opt/quasar/agent/libpython3.8.so.rh-python38-1.0': dlopen: libcrypt.so.1: cannot open shared object file: No such file or directory
3. Check to make sure everything is ok
   systemctl status quasarscan

Testing

Test to ensure that the Quasar Agent is able to connect to the Quasar Server:

./quasarscan commtest

If successful, it will return:Comm test: Success!
If unsuccessful, you will need to interrupt it with ctrl+c. Go back to the local.cfg file to ensure that you have entered the Quasar Server name / IP address correctly. If this is correct, verify that the required ports are allowed.

Check the Agent Has Started

By default, the agent logs to syslog. The agent will log the start up status and the default / configured folder locations (log, data, and tempspace) to syslog upon starting up. You should check that the logs are being generated correctly by running the command:

tail /var/log/messages
