SSL v2 is weak and outdated protocol. All modern browsers and applications support SSL v3 and that’s why you should disable SSL v2 where possible.
Using this command you can check if SSL v2 is enabled:
openssl s_client -connect www.example.org:443 -ssl2
If SSL v2 is disabled you should get a response like this (this is the response you want to get because SSL v2 should be disabled):
CONNECTED(00000003) 11132:error:1407F0E5:SSL routines:SSL2_WRITE:ssl handshake failure:s2_pkt.c:428:
However, if SSL v2 is enabled the response will be a lot longer and include something like this:
... Ciphers common between both SSL endpoints: RC4-MD5 EXP-RC4-MD5 RC2-CBC-MD5 EXP-RC2-CBC-MD5 DES-CBC-MD5 DES-CBC3-MD5 --- SSL handshake has read 1370 bytes and written 364 bytes --- New, SSLv2, Cipher is DES-CBC3-MD5 Server public key is 2048 bit ...
