Summary: configure script not compatible with newer version of net-to

Initial Comment:
Hi.

This is from the old / soon to be disabled again Nagios Plugins bug tracker that used to be at Nagios itself.
I've just copied this bug over. I'm not the original reporter and have no idea about the thoughts about this bug.

This used to be: http://tracker.nagios.org/view.php?id=298

The configure script parses the output of ifconfig to find first_ip. However, a newer version of ifconfig has a different output syntax which causes first_ip to be empty. (first_ip is subsequently used to try to probe PING_COMMAND which fails, causing check_ping to fail).

Gaa, it submitted before I was done. Stupid forms.

This was using nagios-plugins-1.4.15 running on Gentoo.

The following command would seem to work on both the new and old output syntax:

/sbin/ifconfig | egrep "inet (addr:)?" | sed -n -r -e 's/ (Bcast|netmask).*$//' -e 's/^\s*inet (addr:)?//' -e '1p'


One further suggestion (untested) is to simply use 127.0.0.1 if first_ip is undefined add the following line to configure.ac immediately after the first_ip definition attempt.

: ${first_ip:=127.0.0.1}


These are the working ifconfig output.
