Advice on upgrading Ubuntu on OpenVPN server host?

[testudo]

Hi,

I have a fairly standard installation of OpenVPN (i.e. installed via apt-get) running on an Ubuntu server that's in desperate need of a distribution upgrade (running 9.04, planning to go to 10.04 LTS).

Do I have to know anything OpenVPN-specific before running this upgrade? My specific questions are:

If I just backup my config stuff in /etc/openvpn will I be fine if something goes wrong?

I won't have to regenerate keys or certs or anything, right? Once I start up the service again my clients will be able to connect as before?

Thanks.

in theory, yes; I'd also have a look at the ubuntu specific network file (/etc/network ?) to see if there's anything tun/tap/openvpn related there.

I won't have to regenerate keys or certs or anything, right? Once I start up the service again my clients will be able to connect as before?

again, in theory, yes; do you have the master ca.crt and ca.key files? were the file generated in the /etc/openvpn directory as well? or elsewhere on the system?

They were generated in /etc/openvpn. I believe the masters are in /etc/openvpn/easy-rsa/keys still.

Thanks for the help.

You should be good. Just try to keep a backup of everything.

(Just an update in case anyone stumbles upon this thread in the future...)

Everything went fine with the upgrade. The OpenVPN service started automatically and worked just like before.

Thanks for the advice, everyone!
