Local Address failed : Socket bind failed

[fysis88]

Hello people.
I have this problem : when i type to the command line

Code: Select all

  service openvpn start

i get the message that it failed.

Then i run this command :

Code: Select all

 openvpn --config /etc/openvpn/server.conf

and i get this error :

0: Address already in use

Any idea how to fix this?
Thank you very much for your time
P.S : Openvpn is install at a Centos 5 OpenVZ (VPS)
I use this VPS for websites , and this is the only IP i am currently using.Is this causing the problem maybe?

0: Address already in use

the error is self explanatory...

try to find using lsof -i if another proccess already uses port 5900.. (vnc maybe?)

i have changed numerous ports , and run that command as per your instructions...ports are not conflicting..
i have really messed things up...any idea how to remove completely openvpn to start a fresh install?

[maikcat]

what distro are you using?

Linux mydomain.com 2.6.32-042stab044.17 #1 SMP Fri Jan 13 12:53:58 MSK 2012 i686 i686 i386
GNU/Linux

strange thing is , that when i try yum install openvpn , i think it tries to install Centos 6 packages , although i use Centos 5

please post the output of:

cat /etc/redhat-release

ls /etc/yum.repos.d/
