I created this test for the availability of the SSLv3 protocol. There is probably a better way to search for a string that also shows that CBC ciphers are in use, but most people just seem to want to know if SSLv3 is available at all.

A few things to note:

 - Written for bash on Mac OS X so can't say for sure it will work everywhere
 - Uses gtimeout vs. timeout since Mac is weird about those core utils
 - allexternal.txt is a file with one host name or IP per line

script:
 
 for ip in `awk '{print $1}' < allexternal.txt`; do
 if gtimeout 30 openssl s_client -connect $ip:443 -ssl3 | grep -q 'Protocol : SSLv3' ; then
 echo $ip SSLv3 detected >> sslv3output;
 else
 echo $ip SSLv3 NOT detected >> sslv3output;
 fi;
 done
