'''wvdial''' is a console-based software package for setting up and connecting to the [[Internet]] via [[dial-up]]. It is especially good at self-configuring your serial [[modem]] (provided it is not a [[winmodem]]), often rapidly solving the problem of connecting when other programs like [[Kppp]] don't work.

==Installing wvdial==
See [[installing software]].

==Setting up==
To set up your modem connection, just login as [[root]] and type :
<pre>
# wvdialconf wvdial.conf
</pre>
The program will automatically scan your serial ports, find the modem and set it up with the most appropriate parameters.
This is stored in the wvdial.conf file. Move this file to
your /etc directory. Run the command
# ln -s /dev/ttyS0 /dev/modem
Replace the ttyS0 with whatever serial port the wvdial.conf
file has your modem listed as connected to. Edit the file
# /etc/wvdial.conf to insert your phone number, username and password. Here is a sample configuration file:
<pre>
[Dialer Defaults]

Modem = /dev/ttyS2
Baud = 57600
Init = ATZ
Init2 = AT S11=50
Phone = 555-4242
Username = apenwarr
Password = my-password
</pre>
Configuration is finished.
Use the latest version of wvdial(1.54) Earlier versions won't
work with most ISPs. To get the version type
wvdial --version
Remember to add your ISP DNS servers in the
# /etc/resolv.conf file. Insert the line
# nameserver 196.25.1.11
into this file using gedit or wathever your ISP dns server is
Wvdial will look for resolv.conf and wvdial.conf in your
/etc directory only. Make certain they are there.

==Connecting==
When you want to connect,you can launch (as root) :
<pre>
# wvdial
</pre>
and you should be connected to the net.

wvdial will complain if not launched as root. You can circumvent this problem (for example if you want to create a link on your desktop) by finding where is the wvdial binary (for example in /usr/bin) and typing (as root):
<pre>
# chmod a+s /usr/bin/wvdial
</pre>
(This is technically said setting the [[SUID]] bit). This way you can launch wvdial as a normal user and it will run with root privileges.

==Troubleshooting==
In [[Slackware]] 10, I noticed wvdial wrote DNS configuration on /etc/ppp/resolv.conf while reading /etc/resolv.conf. This prevented DNS from working. Copying /etc/ppp/resolv.conf on /etc/resolv.conf solved the problem.

==Howto: when connecting using a SecurID one-shot password generator==
It took me a while to work out how to do this - in the end it was quite simple.

Tardus: WVDIAL solves dialup SecurID problem

== HOW-TO: getting a PPP dialup connection when you have to use a SecurID one-shot password device. ==

It took me quite a while to work this out so that I can dial-in to work without needing a Win box at home. In the end it was simple enough, using WVDIAL and the fact that the numeric password on the SecurID device is good for at least 1 minute.

as root, run '''wvdialconf'''

edit /etc/wvdial.conf with the correct username and phone number, BUT NO PASSWORD.

then, still as root,

'''wvdial password=nnnnnn''' (where nnnnnn is the current number on the SecurID; HINT; wait till a new number appears, then type that in - that gives you the max. time for a ppp connection to be made)

That's it! Worked staright away for me. I'm using Xubuntu on an old IBM Thinkpad A22m with 128MB RAM, and using the built-in modem, which '''wvdialconf''' found OK.

Full details are on my website at http://tardus.co.nr and look under the "Computers" link.

Hope someone finds this helpful.
