Maybe another one for RC4 or TLS.

Unfortunately, it looks like SSL Labs doesn't support anything not using port 443. So, using the less pretty alternatives: openssl s_client -connect ssb.okbu.edu:8910 > CONNECTED(00000003) > 139829631932064:error:140773E8:SSL routines:SSL23_GET_SERVER_HELLO:reason(1000):s23_clnt.c:770: openssl s_client -connect ssb.okbu.edu:8910 -no_tls1_2 > CONNECTED(00000003) > 140473057363616:error:140773E8:SSL routines:SSL23_GET_SERVER_HELLO:reason(1000):s23_clnt.c:770: openssl s_client -connect ssb.okbu.edu:8910 -no_tls1_2 -no_tls1_1 > CONNECTED(00000003) > depth=3 C = US, O = "The Go Daddy Group, Inc.", OU = Go Daddy Class 2 Certification Authority > verify error:num=19:self signed certificate in certificate chain > verify return:0 > --- ... > --- > New, TLSv1/SSLv3, Cipher is DES-CBC3-SHA > Server public key is 2048 bit > Secure Renegotiation IS NOT supported > Compression: NONE > Expansion: NONE > SSL-Session: > Protocol : TLSv1 > Cipher : DES-CBC3-SHA ./cipherscan ssb.okbu.edu:8910 > prio ciphersuite protocols pfs > 1 RC4-SHA SSLv3,TLSv1 None None > 2 RC4-MD5 SSLv2,SSLv3,TLSv1 None None > 3 DES-CBC3-SHA SSLv3,TLSv1 None None > 4 DES-CBC-SHA SSLv3,TLSv1 None None

ssb.okbu.edu:8910 is still broken, but https://okbu.edu/ssb no longer redirect to this port.

Probably because they replaced the system.
