In the server manager panel for sme9admin is a link "Advanced connection tests on services ". This leads to a page like this:
These differents tests may produce false positives, do not take care of them.
Execute them only if you know what they do, and how to analyse their results.
Test http service http@
Test samba service smbcontrol
Test network latency ping
Test ftp service telnet 21
Test ssh service telnet 22
Test pop service telnet 110
Test smtp service telnet 25
I appreciate the caveat above the options. I would like to know what they do *before* I invoke them.
Where are these functions documented?
