How do I turn off SSL v2 on port 10000

How do I turn off SSL v2 on port 10000? This is the last item I have to take care of to get a PCI certification.

Thanks in advance.

Hi there,

You can disable it by logging into Virtualmin, click Webmin -> Webmin -> Webmin Configuration -> SSL Encryption, and for "Allowed SSL ciphers", add this string to the text box:


And that will do it!

Don’t try setting “SSL protocol version” to anything but “detect automatically”, as that won’t work – but you’ll disable SSLv2 traffic with the above string.

Thanks Big

So how would I test whether this has taken effect?

To see it work using SSLv3, type this from the command line:

openssl s_client -connect YOUR_HOST_NAME.tld:10000 -ssl3

That’s what it looks like when a protocol is enabled.

Then try it with SSLv2 using this:

openssl s_client -connect YOUR_HOST_NAME.tld:10000 -ssl2

You should see a few errors, including this one:

12731:error:1406D0B8:SSL routines:GET_SERVER_HELLO:no cipher list:s2_clnt.c:450:

Which is essentially saying that SSLv2 is disabled.

Many Thanks!
