Re: hostnames

[Martin Pala]

Hi,

monit <= 5.2.4 used just  the libc's interface gethostname(), which should 
match the output of the "hostname" CLI utility.

monit >= 5.2.5 gets the hostname also via gethostname(), but then also tries to 
resolve that name to get the fully qualified domain name using system's 
getaddrinfo() API (the resolver is driven by nsswitch.conf and resolv.conf).

Few questions?
1.) which monit versions are running the two hosts which report as 
"localhost.localdomain" and which monit versions those who report correct 
hostname?
2.) what is the "hostname" output on host with "localhost.localdomain"?
3.) what is the "getent hosts `hostname`" output on host with 
"localhost.localdomain"?

Regards,
Martin
