The Linux file system is very robust & usually tolerant of forced power shutdowns.
The journaling file system can withstand unexpected & non graceful power shutdowns.
So I would not worry too much about disruptions to your files.

You should have an uninterruptible power supply on your server though, so that a graceful (controlled) shutdown can be done in the event of a prolonged power failure.

A reconfigure of a server done via the console menu is not a problem, you have been told this before.
Usually you just step through the screens accepting the values that are already there & then reboot, too easy !

Fixing hardware that has failed is another issue though.
It should be easy enough to swap a monitor from another nearby device.

Please follow the howto to install openvpn correctly, you have an old version of openvpn installed for some unknown reason.
You do not tell us how it came to be installed.

Dear Janet, that server is not installed and configured by me. The only thing i know Admin password and where our critical data located and normal domain settings.

but now we are in a much troubled with it because hardware failure. I think it is motherboard Or RAM. This server has RDRam. it is now discontinuing production

We had another server no worked for long time. I am doing the server preparation for boot. after that i will update you all. keep in touch with me.

It does not matter what the replacement server hardware is.
If you install the fresh SME operating system from CD, you can then do a restore from the last known good backup, & your srever should be up & running with the same configuration & data as previously.

Being ready for serious hardware failures is something that a good sysadmin has a plan prepared for. eg spare equipment & drives etc

Hi janet, This time it may be the major issue. The boss gave me our previos server.
this one has Neth service 8.2. This one also give a "Reconfigure and reboot required" msg.
We formated the hard disk which was in sme server and our plan is configure a NAS drive. But this server go internet. and openvpn works. But the msg is a problem. my boss said pls reconfigure and give a reboot to making sure we are ready to audit.

Neth service 8.2. This one also give a "Reconfigure and reboot required" msg.

NethService is a Nethesis' product, and if you're using it you'd ask elsewhere for support..
please don't ask for support on nethserver communisty site, they are 2 different products

thanks stefano. I contact nethsis. as their aspect, we have to contact the person who configured this server. they don't directly give us support.  i was disappointed with nethsis.

Any way. I can download sme server and configure domain in it. then share a ibay. Give DHCP range. and create users in it to use domain. I like to give it the same domain name that we used.

My main problem is "can i implement a openvpn through which existing users can logon"

because there are 12 users meant to use this server over openvpn.

PLEASE READ THE DOCUMENTATION.
You are asking questions that you could easily find an answer for, just by browsing the wiki.

eg see http://wiki.contribs.org/Category:Contrib
which shows more than one contrib for openvpn
Read them & work out which one suits your situation & install that.

Yes, it's possible to reinstall an OpenVPN server as before. The problem is, if you don't want to touch the configuration of the 12 remote users, you'll need:

- To know how it was installed (was it the bridge contrib ?)
- You'll need to configure it exactly the same way as before
- You'll need to find the certificates on the server and use the same one on your new server

If one of these points is missing (especially the certificate part), then you'll have to start from scratch and reconfigure all the OpenVPN clients

[smnirosh]

Danial B., following open vpn client config is using by our company to connecto openvpn server. The usernames were in sme domain and they use their domain passwords to connect.


dev tun
# Verificare che l'hostname del server sia corretto.
remote 184.212.203.56

ca server.crt
tls-client
auth-user-pass
float
pull
explicit-exit-notify 1
verb 3


wht is this openvpn model? is it client to client, or server bridge, or route bridge?

thanks stefano. I contact nethsis. as their aspect, we have to contact the person who configured this server. they don't directly give us support.  i was disappointed with nethsis.

you should not..

BTW, where are you from?

[Stefano]

NethService 8.2 is "just" SME8 with some proprietary packages (not needed)

AFAIK, you can restore a NethService backup on SME

try it first on a VM.. and move to SME9 asap (if you choose to stay on SME)

[Stefano]

interesting..
why didn't you come to italian language forum?

[smnirosh]

We are heading to having a ubuntu server in the future.
but now we need only a openvpn server to connect with clients due to few meetings. because we recruited some workers who works at other offices. At the moment i need special help from you to configure nethservice or sme to connect through openvpn.

In the system nethservice, the openvpn is also not working.

wht is your best recommend?
