check-s2s-ciphers
This is a quick'n'dirty script to check the TLS cipher suites offered by an XMPP server when another server connects. The script is called like this:
check-s2s-ciphers xmpp.example.net
Where xmpp.example.net is the actual host name of the XMPP server (i.e., the
check-s2s-ciphers script won't perform SRV record lookups).
Only those ciphers supported by the local OpenSSL version can be checked.
