Topic: OpenVPN

[smnirosh]

Today i reconfigured my sme server. I answered all the questions as correct i believe. And once it asks for a "DNS address when no internet", I gave no IP address to that last question of the configuration steps.

After reconfiguration the internet is lost. then I changed the RJ 45 cables connected to 2 ports on the server. then internet works. And I manually add NAMESERVER 8.8.8.8 to the resolv.conf file. After all, I tried to connect from home to server via Openvpn it is not connecting. following error msg receiving through openvpn connection window;

what do i have do to connect via openvpn.

[Daniel B.]

You should first tell us which contrib you have installed, and which client is trying to connect, and how you have configured it.....
As a side note, you should not modify directly your /etc/resolv.conf file. This is managed by the SME Server templates engine, you'd better read some documentation

Ok. thanks for the advice.
my version of OS is - Linux 2.6.18 371. i686
I have deployed this server as a Gateway and server mode
I am trying to connect from windows 7

do i have to re configure openvpn?
How can i check if my openvpn is configured as bridge mode or as an othermode?

thanks for your quick reply

There's no builtin OpenVPN server. Which contrib have you installed ?

[Stefano]

"DNS address when no internet"

can you explain where did you see such a request and in which language? I don't remember anything similar in SME's console..

[smnirosh]

How to check which contrib?

[Stefano]

Code: [Select]

/sbin/e-smith/audittools/newrpms


[smnirosh]

Centos sme server 8

[Stefano]

smnirosh, you'd try to answer to the questions you've been asked..

Code: [Select]

rpm -qa | grep openvpn


[janet]

smnirosh

To explain more simply/fully.
Log in as root or a user with root privileges to a command prompt on your SME server.
Then type in the following commands one at a time & record the output & post it back here.
If you use Putty ssh remote access client (free download) from a workstation on your LAN, then you can cut & paste, making it easy to copy the output from the screen after you type these commands. You right click the little logo icon at the top left corner of the Putty window to access cut & paste commands etc.

/sbin/e-smith/audittools/newrpms

rpm -qa | grep openvpn

These commands will show all the additional rpm packages installed, & specifically show the version of openvpn installed (if installed).

[Stefano]

thank you janet.. sometimes I forget to give more explanations

[janet]

Stefano

For most users here, a simple command should be sufficient, but it seems smnirosh needs some hand holding.

[smnirosh]

openvpn 2.1.1-2.e15

[Stefano]

is this the only output?

if so, you missed the smeserver-openvpn package..

so, now, please tell us how did you install openvpn

take a look here: http://wiki.contribs.org/OpenVPN_Bridge

Dear friends, so sad... after power loss this server has no display. But we have another linux server. we are planned to take this server into action. I am so so so sure this server has to be reconfigure again to be worked.

all this things happen to me is DISASTOR.
