Linux client doesn;t connect, Windows does

qwertyjjj

I know the configs are ok as my Windows client connects to the server.
However, when I run OpenVPN form the command line on the client, it connects properly but I cannot browse the internet.
What routing needs to be changed on the Ubuntu client?

hi there,

please post the output of netstat -nr before and after openvpn is up

also check the contents of /etc/resolv.conf file to see if the correct nameservers are listed there

please also post the output of traceroute 8.8.8.8 from your ubuntu client *after* vpn is up.

resolv.conf only has this:
nameserver 127.0.0.1

i believe this is your problem...

try adding to your resolv.conf

nameserver 8.8.8.8

and try again

Nope, same problem.

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.0.1
nameserver 8.8.8.8

I also tried it after restarting network manager but nothing.
It does seem to wipe all the resolv.conf details on doing this so I added them again, saved, and started openvpn, it connectsbut cannot load webpages.

maikcat

one note on resolv.conf file...

this file is read by your resolver EVERY time you use resolver library...

i mean

edit it AFTER you start openvpn and use only the line with 8.8.8.8
try to ping www.google.com and see if it resolves its name to ip...

ps: Network Manager SUCKS!
