multiple IPs for a host?

[Robert Bossecker]

Hi,

in the past i had to check multi homed hosts as well cause we had the 
same problems :-) internal network works and
some other important interfaces were not reachable, i wrote a script 
which retrieves all address records
for that name from the DNS and pings all  of them, unfortunately the 
script is not longer available,
but it worked like doing a gethostbyname and and doing a loop over the 
complete address array
doing pings, so one failed ping should raise a CRITICAL error.
I will scan my disks if i will find some of those code.

Regards
Robert
