Three UK Modem in Ubuntu Linux

Hi there

This is my first post, so please bear with me. I think you will be able to work out how good I am at Linux by reading my questions, which are all about Boris's article called "Three UK 3G modem in Ubuntu Linux". I use Linux Mint Daryna and was delighted to read Boris's article but when I got down to studying it, I had the following problems:

1 Boris says "First run wvdialconf utility to detect and configure your modem. I did it as root. If you want to dial-in as user, you need proper permissions for this." How do I go about "running" wvdialconf utility? That is how bad my knowledge is - I don't know how to run a utility! In particular, what are the differences between running it as "user" and as "root"?

2 After setting out what happened when the wvdial utility was run, Boris goes on to say
"As you can see, it wrote the configuration to /etc/wvdial.conf file. We’ll need to fix it only a bit. Here is my conf after the fixes:"
What were the fixes? What exactly was done to what to produce the result set out on the screen after the fixes were done?

3 Next, the article says "Yes, you see it right. The only changes you need to make is the phone number (if not set correctly to this weird value), user name and password (which are simply “three”). That’s all, really. Now try dialling in:"

My problem with this is that I do not know what to do to dial in. Do I type in a command or what? If it is a command, what is it?

There you are - that is how bad I am! However, I would be extremely grateful and even offer some free employment law advice if anyone could answer my queries.

This depends on what desktop environment you are running. Look for a program described as "terminal", "terminal emulator", or maybe "console". In KDE, the name of the program is Konsole. This will give you a shell CLI, then just type "wvdialconf" and hit enter (assuming the wvdialconf program is installed).

root is the all-powerful user who can change anything on the system. Sometimes this is necessary, usually for administrative tasks. However, running a program as root can be dangerous because a bug in the program (or, unlikely, a malicious program) could wreck the system. So, unless necessary, run as a normal, unprivileged user. This way, a program can only affect certain parts of the system that the user has access to. Normal users usually just have permission to read and write their home directory, which is probably /home/insert-user-name-here. The home directory is substituted with ~ often. A particular user's home directory can be substituted with ~insert-user-name-here. While running as bob, ~ probably refers to /home/bob, which can be referred to as ~bob by any user.

Use su or sudo on some distros (especially Ubuntu) to temporarily switch users in a shell. If you do not specify another user, root will be assumed. su will ask you for root's password. sudo will ask you for your password, however you can only do specifically enabled actions with sudo.

As for dialing in, I do not know. I have not used a dialup connection since long before I started using GNU/Linux. I think you need a program called ppp or similar. There are might be some graphical tools installed on your system if you look around (look for PPP in the name or description).

For your other questions, it will help if you link to the article.

Thank you very much - I understand what you have written so far. The excellent article to which I am referring can be found at:

I realise that there is no need to offer rewards. It is just that I certainly won't be able to reciprocate your Linux help.

the article

I read the article now and I understand questions 2 and 3. It might be hard to tell in whatever fontface you have your browser set to use for code, but the lines

Phone = *99#
Username = three
Password = three

have bold in them. The changes emboldened are what you need for your specific ISP. You should have been told this or given it in some paper when you got the modem (unless you got it without service). If not, contact your ISP somehow.

To dial in, just run wvdial. Alternatively you could use gnome-ppp which automatically reconnects if the connection goes down or any other graphical PPP frontend (like KPPP if you use KDE, which can also autoreconnect).
