A quick bash script for sanity checks of a Linux web server.


curl -L | bash

Description of the checks

1. Out of memory conditions

2. Broken outgoing email

This is a performance sanity check: telnet to 25 of external mail servers works ?
Note that it is common for Amazon AWS (blocked outgoing port 25 can yield very poor WP performance when SMTP plugins are in use).

3. Missing swap allocation
