Hi Guys,

I have just signed up to your service and tested successfully with a Windows 7 workstation.

My problem is that I cannot get a connection with either the Linux CTC Ubuntu client through Firefox or through the Terminal with open vpn on my Ubuntu 10.10 32bit laptop.

Terminal \ OpenVPN :

ben[at]Laptop01:~$ openvpn --config /etc/openvpn/client.conf --ca /home/ben/Downloads/ca.crt

CTC Through Firefox :
Once I enter my username and password it just stays at ‘Connecting…’ at the top of the screen.
If I click on ‘Configure Client’ or ‘Show Config’ I see the message ‘Config is not available!’

Any Suggestions on how to get either of these two methods to work for Ubuntu 10.10 32bit?

Cheers

Ben

UPDATE - Using ‘Sudo’ at the terminal command line got the openvpn client working however I would like to get the official CTC Firefox client going. Also is there a way to only have traffic for a specific domain use the CTC? ie… hulu.com

Further Update…

I was able to import the config.conf file into Ubuntu’s VPN section the network manager and get a successful connection. This works however AAAALLLLL internet traffic is going down the tunnel which has slowed everything down. Next chalenge is just to figure out how to define only hulu.com traffic to use the VPN…

  1. Disable default route through TC
    Add into your Openvpn configuration file:
    route-nopull

  2. Add routes for “hulu.com” through TC:
    route 92.123.65.17 255.255.255.255 vpn_gateway
    route 92.123.65.25 255.255.255.255 vpn_gateway

where “vpn_gateway” - special OpenVPN variable, not a special IP.

Thanks for the suggestion however the CTC client doesn’t appear to be working within Ubuntu 10.10 so I am trying to figure out how to use the native Ubuntu VPN client through network manager to only route to specific networks through comodo VPN tunnel…ie hulu.com.

I assume I need to configure the ‘IPv4 Settings\Routes’ however when I enter any details in there the VPN will only connect for a few seconds and then fail. This problem might be out of scope of this forum however I thought I might throw it out there incase others happen to have the same configuration working.

Is the CTC client suppose to work on Ubuntu 10.10?

Cheers

Ben

Probably, it would be better to follow the recomendations given above and edit the Openvpn configuration file, rather than use Network Manager.

CTC Client doesn't work on Ubuntu 10.10.
