Free dial up software for linux

tkdial is a small tool for starting dialup connections on various network devices such as ISDN.
Each network device (ippp0, ippp1, ...) is configured for a different ISP (internet service provider). With tkdial the user can choose a ISP an the computer dial with this configuration to the internet.
Enhancements:
- new option "-c" for configuration file in tkdial
- new option "-h" for usage help in tkdial

wxDialer is a simple and easy to use dialer program which allowes to make and receive calls on your modem. This program is based on win9x dialer.exe application.
A microphone is required, and it is suggested that you also have
headphones instead of using your speakers to prevent any nasty feedback. A
telephone headset, naturally, is best for this.
This is program is not designed for voice-over-IP (VoIP) or to dial to ISDN
modems. It dials out using your every day dialup modem, and makes your
computer one big handset.
To run wxDialer, its simply a case of using the appropiate command
(ie: python /home/aaron/python/wxDialer/wxDialer.py) without any arguments. It
doesnt matter if you specify arguments, they are ignored (for now ;)
wxDialer stores configuration information in the dir $HOME/.wxDialer - if it
doesnt exist, it is created along with the config file containing default
values.
Enhancements:
- Fixed a bug where the modem may fail to initialize properly, causing it not to dial out.

Dial2net is an application that configures a PPP (dialup) connection according to the ISP specified by the user. Both PAP and CHAP protocols are supported. This application is aimed toward users new to linux that are trying to get thier system configured so they can access the internet via a ppp connection. The scope of this project is to create a simple, easy to use application that gets the job done veri good.
What differs is a few things by other applications:
1. Give the user the ability to choose thier ISP from a list to make things simpler and reduce the need for manual configuration.
2. Include an application (Lan2Net) that will setup a Local Area Network that will share an internet connection.
3. A slew of useful tools that make day-to-day use of a ppp connection easier.
After the initial installation...
Run dial2net to dial out and dial2net -d to disconnect. If you need to reconfigure dial2net for any reason, run dial2net -s again for setup mode.
Enhancements:
- added autoredial function
- minor bugfix

c2cWebdialer provides an extension which works with a CISCO IP telephony solution to provide an easy way to dial phone numbers.

C2cWebdialer extension works with a CISCO IP telephony solution to provide an easy way to dial phone numbers on web pages. Just select the phone number and choose "Dial with CISCO Webdialer" from the contextual menu !

C2CWebdialer has to be configured through the "Click2Call parameters" menu, it needs two parameters :

* The IP address or the DNS name of the CISCO CallManager on which the webdialer service is launched

* The dial out prefix that C2cWebdialer will put before the selected phone number

The webdialer feature must be activated on the CISCO CallManager.

Multinet is a curses-based solution to sharing a dial-up Internet connection using IP masquerading. It keeps track of time spent online, billing information for each user, and user manangement (so that users cannot kill each others connection).

The program depends on two scripts that bring-up the ppp connection and shut it down again.See the multinet.c code for the NETSTART and NETSTOP defines which specify where these scripts are. In my case, the up script is basically a line that says:

/usr/sbin/pppd call freeserve

...with a few other misc. bits and pieces. The down script basically just has this line:

kill `cat /var/run/ppp0.pid`

Your scripts may be different, but if you use ppp and chat scripts they are going to be pretty similar.

Net activity is logged to a file (defined in multinet.c). This is a plain text file that shows the userid, time, duration and cost of each call.

When you want to start a net connection, simply type multinet. If another user is currently using the Internet, you will be told as much and the program will exit. Lucky you - you can use the net and hell pay for it! Be nice and dont use much bandwidth though, or he might
get upset.

When you make your own connection, dont quit the program! You must keep it running until you press D to disconnect, otherwise everything will go pear-shaped.

When you disconnect by pressing D, to program will calculate how long the call was and how much it cost. It will tell you this information as well as logging it to its log file.

killppp purpose is to kill ppp pid after n time of no traffic. This is especially useful for dial-up users who pay per time-unit of being connected. The typical use for it, is to start a large download along with killppp and go away. The script will shut down ppp after the downloading is done. Thus saving unnecessary cost of unused network connectivity.

Depending on how your linux is configured you may need to be root to have the right to kill a ppp process and it may have to be the ppp daemon (pppd).

To find the pid of your ppp process type: ps aux | grep ppp

How this script works? Once activated, killppp checks every minute for network traffic on the ppp0 device. As long as data is passing through, killppp does nothing. Upon no traffic killppp starts counting time until it reaches the specified time and kills the ppp process.

killppp [-hl] < pid > < n >s|m|h|d

Options:

< pid >, process ID
< n >s|m|h|d, n seconds|minutes|hours|days of no traffic
-h, usage and options (this help)
-m, manual
-l, see this script"

DUD provides a download manager for dial-up users.

DUD is a collection of scripts for managing downloads over a dial-up connection.

The scripts are meant to be started by the ip-up.local script, and notify the user who initiated the download on its completion.

DUD internally uses other download tools such as wget or axel for carrying out the actual download.
