Not resolving /etc/hosts

[nvargas123]

Hello everybody,

I've been trying to make a Fedora Core 11 box to resolve using its hosts file but it just wont.

The /etc/hosts file reads:

127.0.0.1 localhost.localdomain localhost
172.16.100.132 server.domain.com server

I've checked the /etc/host.conf file and it reads:

multi on
order hosts,bind

And the nsswitch.conf file reads:

hosts:      files dns

When I run the host `hostname -f` it still shows the DNS IP number and not the address listed on the hosts file:

server.domain.com has address aaa.bbb.ccc.ddd

Tried rebooting and still no change, but when I ping the hostname, it uses the hosts address.

[root@server etc]# ping `hostname -f`
PING server.domain.com (172.16.100.132) 56(84) bytes of data.
64 bytes from server.domain.com (172.16.100.132): icmp_seq=1 ttl=64 time=0.033 ms
64 bytes from server.domain.com (172.16.100.132): icmp_seq=2 ttl=64 time=0.025 ms
64 bytes from server.domain.com (172.16.100.132): icmp_seq=3 ttl=64 time=0.023 ms

Any ideas?

Guess: is it resolving using your /etc/resolv.conf file? But that doesn't make much sense either. Sorry.

You use comma in your /etc/host.conf, but it states on the man page:

Fields can be separated by white space, consisting of either one or more spaces or tabs.

Did try a white-space?

'hostname' w/o arguments just returns the value of the (man 2 uname) uname syscall, and this has no necessary connection to any network hostname. BY CONVENTION uname 'nodename' string should be a FQDN, but many systems violate this recommendation. So 'hostname w/o argument doesn't consult /etc/hosts ,nor dns or anything else - it makes a local syscall.

Since the uname.nodename may be an unqualified hostname, one suggested way to get a fqdn is to first lookup the IP address for the unqualified nodename, then second do a reverse lookup of the IP address to get the fqdn. Perhaps this is what ancient (F11) 'hostname -f' does.

The current hostname calls 'getaddrinfo' with the uname value, and this works as expected (stops at /etc/hostname, even despite the typo) .
