Xen users - Jun 2007 - Connection-Problems to servers of my domain (2)

Hello people,

i asked for help due to connection problems to servers installed in my
"xendbsrv00" domain. the problem still exists even if iptables and
ip6tables are disabled on both sides. the connection to the sshd on my domain
works perfectly. I still was not able to figure out why i can connect to sshd,
but not the the installed mysqld and postgres daemons.

Greetings


thomas

Hello,

the security-related settings were properly adjusted for both the mysql and
postgres servers (due to a routine installation). A "nmap -sT xendbsrv00 -p
3306" or "nmap -sT xendbsrv00 -p 5432" call on my master-machine
returns
with
PORT     STATE  SERVICE
3306/tcp closed mysql
PORT     STATE  SERVICE
5432/tcp closed postgres
although mysql / postgres are definitely running... Im quite confused, this
shouldnt be...

iptables / ip6tables are disabled!!! :-(
