linkchk is a network interface link ping monitor.

linkchk is an active network link monitor (c) 2001 Jens-Ulrik Petersen juhp@01.246.ne.jp

It is licensed under GPL 2 and comes with no warranty.

The latest version can be found at: http://www.01.246.ne.jp/~juhp/linkchk

DESCRIPTION

By default it repeatedly pings the IPv4 (or IPv6) address of the default gateway of a given interface appearing in the routing table and shows the link status in a small gtk window or in a tty. With appropriate options it can be used monitor any interface with a gateway or to ping any specific host. gtk+hs is currently required to build it. The reason for starting this project was to monitor an unreliable ppp link at home with a tendency suddenly to start dropping packets after a while.

Currently it uses some options of ping, ping6 and netstat that are probably specific to Linux, but porting to most unices should be straightforward I imagine. If you get linkchk working on another platform and can send me patches, or can send me "ifconfig" and "netstat" output from your platform, then I will be happy to try to fold them into the distribution.

If you find linkchk useful, or have comments, feedback or other contributions, I would be glad to hear from you.

BUILDING

In order to build linkchk you need to have installed

Once you have those in place, you should be able to build in the standard way; ie something like:

% ./configure
% make
% make install

should make and install the executable "linkchk", that you can then test by running. "linkchk --help" lists its options.

See the generic INSTALL instructions for more information on building.
