<p>I'm using OpenVPN to setup a VPN server on a desktop with the
client on a laptop also using OpenVPN. Both machines are Ubuntu
Precise Desktop. All that I want to do is to access website
securely using OpenVPN when away from home by leaving the
desktop switched on. I've followed the Ubuntu Community Guide
for OpenVPN on a Ubuntu Server and everyting is OK except for a
line on the client's /var/log/syslog repeated many times: shown
at end of this message. Any ideas?<br>
