[Sbcl-devel] ICMP echo anyone?

[<ha...@al...>]

I'm looking at making a system monitoring app (reimplementing 
cmd.php/cactid from the cacti monitoring framework) .

I've come to the part where I need to establish host availability, and 
need some ping functionality. Two possible strategies, hinting at a third:

A) Look at the C source of the ping command to see what needs to be 
done, dig through the sb-bsd-sockets code and build upon that for ICMP 
and udp ping functionality.
B) Run the ping command as a sub-process.

B is not really an option when you have several hundred hosts to check I 
believe. (please tell me I'm wrong, even though running /bin/ping is 
lacking in macho appeal)

Then there is the third option: anybody got an extension for the 
sb-bsd-sockets to make a nice interface for ICMP messages? Would this be 
the right thing to do?

If I do this myself in lisp, it would not be integrated into 
sb-bsd-sockets and would be really minimal. With some help and a 
starting point I think I might be able to assist in doing it properly 
though.

So: Anybody got a starting point for integrating ICMP messages into 
sb-bsd-sockets?
