Default account permissions......editing /etc/wvdial.conf - 01-26-2009, 09:21 PM

Hi all

Still quite new to linux but I'm currently trying to install a new mobile broadband usb dongle (Huawei E156g on the 3 network (uk)). I've trawled the net and managed to find a method which should work however it requires me to edit /etc/wvdial.conf which my current user account permissions won't allow.

Could anyone give advice of best practice for editing this file? Should I log in as root (instructions required as I don't even know the password) or update my account to give it root privileges (again instructions would be required)?

Any help greatly appreciated.

To run any command as the root user in Ubuntu, open a Terminal and type:

$ sudo <command>

Sudo will ask for your user's credentials (not the root user's - your current user account's password is what it'll want), then it will launch the program for you as the administrator.

For a nice GUI editor for the config file, I'd recommend gedit. Try this:

Applications -> Accessories -> Terminal
$ sudo gedit /etc/wvdial.conf
make your edits
save the file, and exit the editor...

Congratulations on your new broadband equipment! Keep us posted on how it turns out -

It should actually be:
gksudo gedit /etc/wvdial.conf
Ref: http://www.psychocats.net/ubuntu/graphicalsudo

And consider backing up the original before altering it:
sudo cp /etc/wvdial.conf /etc/wvdial.conf.bkp
Those 3 dongles should work with Ubuntu just fine. There are GUI frontends for wvdial that may simplify things too.
