To disable the SSL2.0 protocol (thus forcing 3.0),
for apache 1.3, find the line:
#SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
and change it to:SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:!SSLv2:+EXP:+eNULL
Note the 2 changes: a) remove the # character at the beginning of the line, and b) change +SSLv2 to !SSLv2Â
For apache 2.x, do the same thing, but instead it will be in the /etc/httpd/conf/ssl.conf file, or for the new apache system, /etc/httpd/conf/extra/httpd-ssl.conf  (if you have both files, just change it in both).
