Vnc

[Erwin123]

I tried to create a KVM ve using an openexchange iso I downloaded.
After starting the ve the cpu stays 100%, unfortunatly I can not see whats happening because the VNC/Monitor is not working an any of the computer I have around.
I installed the requested jave plugin, but nothing happens.
Anybody knows what I'm doing wrong?

Well I've found a computer that the vnc works on (still no idea why it won't work on others, probably something java related).

Now I have a different problem.
In a VE with debian, I installed postfix. Sending mail is no problem but connections on port 25 are refused.

from the local prompt:

zarafa:/etc/network# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 zarafa.mydomain.net.localhost ESMTP Postfix (Debian/GNU)

Again from the local prompt (xx is actual ip);

zarafa:/etc/network# telnet xx.x.xx.xxx 25
Trying xx.x.xx.xxx...
telnet: Unable to connect to remote host: Connection refused

from remote servers connections to port 25 are also refused.

ifconfig:

Other ports have no problem, just port 25.
Anyone any ideas?

What does the IP_ADDRESS line look like in /etc/vz/conf/NNN.conf?

Is the IP address you are using in the VZ container in the same subnet as your host system's ethernet interface?

The ip adress in that file is correct, the ip is on the same subnet as the node its on. All other services and ports are working just port 25 is not reachable over the ip adres...

Oh, duh. I just looked more closely at the output you provided.

You need to configure postfix in main.cf to listen on more than just localhost.

Right now Postfix is bound to 127.0.0.1 only.
Look for the line in Postfix's main.cf that says "inet_interfaces"

 

[Erwin123]

Great, thanks!

it now looks like:

mynetworks = 127.0.0.0/8
inet_interfaces = loopback-only

I changed it to:

inet_interfaces = venet0:0, loopback-only
recipient_delimiter = +

Then I get:

postfix: fatal: config variable inet_interfaces: host not found: venet0:0

Guess i'm doing something wrong here

 

[tog]

Yeah, it doesn't want a physical interface, it wants an IP or multiple IPs.

Example:

inet_interfaces = 200.111.222.2, 200.111.222.4

or just:

inet_interfaces = 200.111.222.2

 

[Erwin123]

And it works
Thanks a lot!
