Perform Network Tests on a GWAVA 4 SMTP Appliance

How can I test my system's connectivity?

At the time of install, a script is run to test your network settings to confirm connectivity. If needed, that script can be run again later to perform several connectivity tests for you. The script is located under /opt/beginfinite/gwava/assets/scripts. To reach that directory, use the following command: G4SMTP:~ # cd /opt/beginfinite/gwava/assets/scripts/ To run the script, use the following command: G4SMTP:/opt/beginfinite/gwava/assets/scripts # ./test_net.sh The script will launch and automatically perform several connectivity tests. It will perform a ping to another server, test downloading from our download server and test outbound traffic on port 25. Results will generally look similar to this test: ############################ Test Network ############################ Your network settings will now be tested. If there is a failure, you will be directed to resolve the problem before continuing.

Ready Port 25 access works correctly General connectivity good. Successfully used port 80. Port 25 outbound successful. Your network settings appear to be correct. This script tests only basic connectivity. Linux provides a number of other tools for troubleshooting connectivity issues. Some of those common tools are netstat, nslookup, ping, traceroute, telnet and route. Those commands can be used to test your system’s connectivity more thoroughly.
