Summary: Configure nagios-plugins inside vserver hangs

Initial Comment:
nagios-plugins-1.4.9
./configure
Gentoo
Tested on x86 AMD64
gcc

Configure nagios-plugins hangs inside vserver environment (or any other environment without IP 127.0.0.1) as soon as the configure script tries to
check the ICMP syntax.  

Reproducible: Always

Gentoo output:
checking for ps... /bin/ps
checking for ps syntax... /bin/ps axwo 'stat uid pid ppid vsz rss pcpu comm 
args'
checking for ping... /bin/ping
checking for ping6... /bin/ping6
checking for ICMP ping syntax...

ctrl-c
/usr/portage/net-analyzer/nagios-plugins/nagios-plugins-1.4.9.ebuild:
src_compile aborted; exiting.

The reason is that 127.0.0.1 is hardcoded as localhost IP inside the configure script. This is done for checking ICMP syntax and  nslookup syntax. But
vservers don't have this IP.

The following files contain 127.0.0.1 hardcoded:
configure.in
check_dig.c
check_pgsql.c
check_smtp.c
check_tcp.c
check_ups.c

I tested these five checks inside a vserver environment and check_dig was the only one which didn't work. As far as I understand the code the reason is that check_dig calls the program dig which fails in case of 127.0.0.1. The others use system calls for their operations.

To fix it I modified configure.in and used the hostname in check_dig.c. I attached a patch for the two mentioned files. For Gentoo you find a modified ebuild below which contains the patchs as well. I tested it on two different Gentoo machines and it worked for me.

Norbert,

Thanks for the report. Would using "localhost" be okay in configure.in?
What impact would this have in IPv4 or IPv6 environments?

Ton
