@hackage linkchk0.0.2

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

• gtk+hs: a recent version (I'm using 0.12.1 from cvs) (available from http://www.cse.unsw.edu.au/~chak/haskell/gtk/).
• c2hs: a recent version (I'm using 0.10.1 from cvs)
• ghc: a recent version (I'm using 5.02)

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.
