Free isp software for linux

isp-connect project is a set of scripts which should make it easy to connect from a single GNU/Linux workstation to an ISP using a dial-up connection.
It supports a single PPP connection over ISDN or modem, and support is planned for raw-IP (over ISDN) and hooking up to several providers at one time.
The package comes with the helper script schedule.pl, which is a kind of an offline cron.
It gets a crontab-like file as input and executes the commands given in the file not exactly at the times given (like cron), but only when it is executed itself (of course, because it is not a daemon) and the time in the config-file has passed.
Enhancements:
- Modem support
- Signal, when line goes up or down
- Disconnect can close all active connections

Iptoip is a perl script to help maintaining an ipvsadm table on a non fixed ip adress or an intermitent connection.
It is specially useful when using an intermittent internet connection or when your ISP breaks conections to reaffect IP addresses (like in France) It use the ipvsadm tool to build and update a forwarding routing table.
The program is written in perl. It uses a configuration file to know which interface to use, which port to forward, and to which box in the internal network. For example your external ip is xxx.xxx.xxx.xxx and you forward the http default port (80) to the computer zzz.zzz.zzz.zzz in your internal network. Everytime youve got a new public ip you should launch iptoip to update your ipvsadm table with your new ip yyy.yyy.yyy.yyy:80 to zzz.zzz.zzz.zzz:80
The name iptoip have no particuliar history, it was found when I was asked by sourceforge to find a name for my project, before it was : toto, test, titi, test1... But anyway, I think iptoip expresses well the idea to transfer something from one ip to another ip...but you know...hey..."whats in my mind" (c) Pixies.
Main features:
- external XML configuration file
- only one file for several configurations
- check if IP is really public
- able to use syslog to log in /var/log/messages
- no-check mode
- verbose mode
Enhancements:
- add udp/tcp support ( Thx Florin Grad )
- change verbose mode
- now an update line is dropped for every forward we add
- should me a lot clearer than before with some cosmetic changes
- remove redundant displaying
- fix usage of alternate config file
- now we can use "iptoip file.xml" we dont need to do "iptoip ./file.xml" as before
- update man/doc pages

mysqlIPM is a Web-based IP address, router, firewall, and quality of service manager. It includes provisions for MAC hardware addresses, and tftp files for router backup.
In a nutshell mysqlISP assigns (and deploys across network of ISP servers) products to ISP clients (customers). These products consist of one or more sevices that similarly consist of one or more service parameters. End user level, Reseller level, Admin level and Root level record and operation permissions have been built in from the ground up (based on years of ism|2 experience.) Even ISP employees would have a hard time bypassing cgi security measures. The products are deployed for new/mod/del operations via an asynchronous job queue system and read by subsystem servers via mySQL tcp/ip connections (or if local much faster and secure mySQL socket.) Client side subsystem root command line operations done with crontab entries read the master mysqlISP job queue -this is very secure and much better than root permission httpd daemons...shudder. For the PRO ISP all this should be done with a second NIC card on all edge servers making up a private ISP management LAN. But mySQL GRANT command with passwd and user@hostip makes system pretty much secure, except for possible packet sniffers run on non switched hub local -unlikely unless server is hacked. VPN, ssl tunnels etc can be used also for mySQL connections between servers.
unixservice.com commercial:
Non GPL software like unixservice.coms ism|4 (but at least very inexpensive -less than $100/Month- with sitewide license, install, monthly support hours, and yes it is opensource -installed on your server. Support is local to your region NA, SA, Europe etc.) can wrap mysqlISP for a non technical 100% customizable look and feel -skin template sets. ism|4 can also be used to automate billing of ISP clients (ACHDebits, credit card, email, checks, cash etc...electronically, periodically, one-time...etc.) Propietary closed source ISP software companies hate us believe me.
Enhancements:
- VERY IMPORTANT: Some accounting queries require mySQL 4.
- Added accounting invoice generation and payment processing.
- Added special client usage products.
- Added accounting test suite .mysql SQL files.
- Changed tInstance schema (again...sorry) for accounting specs.
- Minor changes in many table pages for improved application use.

PHPlist is a mailing list and newsletter manager that allows posting via a Web page. PHPlist works well when used for announcements, and can handle very large email address lists. Users can sign up to multiple lists, but will only receive a single copy of cross-posted messages.
When signing up, users can identify their geographical location, and messages can be targetted to these. You can add place holders in your email that will be replaced with personal details (such as the persons name).
Users can update their own information, and unlike many other mailing list systems, they can change their email address. HTML emails are supported.
Main features:
- Posting to the mailinglist is via a webpage. It is therefore a one-way announcements system, directed from you to your audience.
- It is designed to be able to deal with a very large amount of email addresses. If a sending fails halfway, the next process for sending simply continues where it left off, without duplicating emails to users.
- Users can sign up to multiple lists. If a message is sent to multiple lists, they will only receive one copy of the email and not as many as the number of lists they are subscribed to.
- Templates. It is very easy to adapt the public pages of the system to fit into your website. You can upload a header and a footer of all pages to make the pages fit your requirements.
- Attributes. You can specify information you want to get from users when they sign up. When sending a message, you can use this information to select the users that need to receive the message. For example you can add geographical information. When people sign up, they can identify the geographical location theyre in and when sending an email you can determine which locations need to receive the message.
- Multiple subscribe pages. You can design your own subscribe pages and you can have different pages allowing users to sign up to a selection of your lists and only enter a selection of your pre-defined attributes.
- Personalisation. You can use the attributes you define in the emails you send, to make every email personal to the user who receives them.
- PHPlist supports HTML emails. If a user indicates they want HTML email they can receive it that way. If unknown the system has a bias to send text emails to users.
- Multiple List managers. One Super user can assign lists to multiple list managers, who can control their own pool of users and lists. The Super user can "prepare" messages that can be chosen by list managers to send to any of the lists they control.
- Easy import and export. Use TAB delimited files to import your existing list of users or to export the users on the PHPlist system for use in your in-house database.
- Personal Details. Every email a user receives will contain a personalised URL to update the users preferences. This way your users can update their own information and your database is always up-to-date. Unlike most other mailinglist managers users can change their email address when updating their personal details. This is a major benefit to both you and your users as many people often change their email address, and this feature makes sure that they dont disappear from your view.
- Attachments. You can add attachments to your message. They will be included in the HTML emails. The users who receive text will get a special URL mentioned in their email telling them where to download the attachment from your website.
- Batch Processing. To facilitate shared hosting environments, you can specify the maximum number of emails to send in a time period you identify. This can also be overridden by ISPs who can set these values server wide to apply to any PHPlist installation on that machine.
- ISP Friendly. Apart from the limit on values for batch processing that the ISP can enforce, there is an additional option for ISPs to suspend sending during busy times in the day.
- Embargoed sending. You can create a message and tell the system to only start sending it at a certain date and time in the future.
- Repetition. A message can be repeated automatically. Currently this is only useful when the message has "filesystem attachments", because they are refreshed at time of sending.
- User management. You can use several in built tools to handle large databases of users. Users can be reminded to confirm their subscription and invalid emails will be found automatically, or fixed whenever needed.
- Bounce handling. Bounces can be processed and users will be automatically unsubscribed when too many emails to them bounced. This can be corrected by the administrator in case the unsubscription was incorrect.
- Automated PDF creation. To ensure users can read the message regardless of mail reader, the message can be automatically converted to PDF and attached to the email.
- RSS feeds. PHPlist can be set up to read a range of RSS sources and send the contents on a regular basis to users. The user can identify how often they want to receive the feeds. For more information about RSS click here
- Easy install. Just copy the files to your website folder, tell the login details of the SQL database and its done.
Enhancements:
- Click tracking has been improved a bit.
- phplist can now also pre-calculate the (bandwidth) size of a mailout.
- Several other smaller issues were addressed.
