Configuring 24Online Client on Linux

Its really great to have a Linux client, more from a learning initiative as showing off to the buddies on how geek are you since there are too many Linux geeks out there. Anyways i had huge trouble in configuring the client. The main reason being am on a dual boot and i have just one computer so if i need to Google i have to reboot to windows and get the information i require.

Well in Ubuntu 9.04 the network connections link is broken, if you get online you might get an update but till then you cannot use the network connections at all

You need to get your hands dirty by opening the interfaces file in the /etc/ directory.

Here are the steps i had to do, well they are spread over a few days due to lack of time and everything else including laziness.

  • from your windows side download the linux client from the server, this is the easier part.
  • Setup your ip by getting to /etc/interfaces file.

gksudo gedit /etc/network/interfaces

auto eth0:1
iface eth0:1 inet static
network x.x.x.x
broadcast x.x.x.x
gateway x.x.x.x

Reason for gksudo is that it is a better known practice to using sudo to open graphical editors

  • Now Restart your networking service by running sudo /etc/init.d/networking restart
  • Now setup the DNS, note in the windows ip address entering place the dns is at the same place not in ubuntu though


    sudo vi /etc/resolv.conf


  • now copy the installer tar to the home directory and run $ tar -zxvf CyberoamLinuxClient.tar.gz
  • Then post getting inside the directory by running cd crclient <enter>; run ./crclient –s
  • then ./crclient –u

  • You are there 🙂
