Linking Ubuntu Servers

[dalitso]

What is the easiest yet reliable way of linking ubuntu servers? Like in a scenario where branch servers need to link to head office server in services like samba shares or more.

You may check OpenVPN (www.openvpn.net). Its very easy to setup yet robust, stable and secure.

You may set it up using static key instead of creating certificates. Please check http://www.openvpn.net/index.php/ope...ini-howto.html

Do come back here in case any queries, I shall be glad to assist.

Openvpn's basic setup worked fine. I am just working on creating keys so I can establish an auto connection on the client side (server 2).

Although following this guide http://www.ossramblings.com/configur...n_ubuntu_hardy

gives me this error:

Using configuration from /etc/openvpn/openssl.cnf
/etc/openvpn/keys/index.txt: No such file or directory
unable to open '/etc/openvpn/keys/index.txt'
31286:error:02001002:system library:fopen:No such file or directory:bss_file.c:352:fopen('/etc/openvpn/keys/index.txt','r')
31286:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:354:

when I create the keys with

./build-key-server server

./build-key client-name

But I figure the keys will still be created even if there's that error, right?


Anyway, on the basic(documentation) open vpn setup, I can access the files both by using samba or nfs.

I have realized that mounting the folders of server 1 on server 2 via either samba or nfs results in those folders being unavailable once the internet connection is not available.

I mounted nfs this way

mount 192.168.1.20:/export/share /home/user/share

I was just testing so I didn't mount in /etc/fstab

Is there a way server 2 can still have the files in its folder /home/user/share/
even when the connection is absent?

I am going to use rsync.
