[Xen-users] domU MySQL not available externally

[Jimmy Cullen <jimmy@xxxxxxxxxxxxxx>]

Hi,

I am a newcomer to xen and have a problem with MySQL access on domUs. dom0
is Debian Squeeze and two domUs are Squeeze also. I am installing a mail
server on one domU and need MySQL to be available externally, however for
some reason it is blocked, while other services e.g. IMAP and POP3 are
available externally. Example nmap output is given below. I have not added
any rules to iptables.

One possible problem I can think of is that I had installed cacti on dom0
to monitor load etc., which also required MySQL. When I discovered the
problem with domUs not being able to make MySQL available externally I
uninstalled cacti and MySQL, but the problem remains.

Any help would be much appreciated.

Jimmy
