A small and useful program to
login and keep you connected to:
Telia HomeRun
Telia Broadband (Flexicom / ADSL)
Telia Internet Cable (ComHem)
Tiscali Bredband

[ Download ] [ Support ]


Login and Logoff
You can connect or disconnect by one simple command

Auto Start and login
The daemon can easily be started upon boot through the standard rc.d. If the first connection try fails it shows a warning message (only once) and automatically retries again in 10 sec. until the connection is successful.

Keep Alive
To avoid getting disconnected all the time I have a keepalive feature with user setable delay

Easy Reconnection
IF your get disconnected in spite of the keep alive function, all you have to do is to sent a new start command.

System Requirements

LF Connection Keeper is programmed in ANSI C for 32 bit Intel Linux systems using GLIBC 2.0 / 2.1.

Note that for the moment I only release binaries, we'll see what happens in the future...

Since LF Connection Keeper is designed for use with Telia's broadband Internet services it will not be of any use to other people.
