CentOS - Feb 2013 - The moving of VNC port from 580n to 590n

On my 'older' systems that include Centos 5.5 and Fedora 12, vncserver 
is running on ports 580n where n is defined by userid in the 
/etc/sysconfig/vncserver

I just spent a bit of time getting it working on my new Centos 6.3 
server and found it listening on ports 590n.

When did the change occur?

And guess I should test out where it is on Fedora 17...

There's a lot of conflicting information on this topic on the
Internet. Most current VNC servers seem to listen on port 590n. I've
seen it claimed that a) port 580n is not used and can be blocked, b)
580n is used for the Java VNC client, c) 580n is used for browser
requests for VNC (probably via the Java VNC client, I'd guess).

I don't know when the change occurred and it may be that it happened
when RH changed from one VNC brand to another.

Serving multiple ssl certificates requires SNI on server and also
client support.

this works on Centos 6 without messing up openssl libraries :)

Biggest problem indeed with sni is that all intended clients must also support
it...

You might consider using IPv6, and give each (virtual) http-server its own
address.
That works very well indeed, but chat24 is that here also the clients must be
able to connect over v6 ;-)

if you have multiple ips configured then this works out of the box in el5.

if you need sni support (one ip for multiple ssl sites) then el6 should provide
the necessary support (openssl etc.).
