host issue to resolve itself

karlochacon · 02-17-2011, 10:23 AM

hi guys

I have standalone Suse 10 SP3 that when I run

Code:

# hostname
webserver

but when I run host command

Code:

# host webserver
;; connection timed out; no servers could be reached

I would like to get the IP when I issue

Code:

host webserver
x.x.x.x

and the name when

Code:

host x.x.x.x
webserver

in /etc/hosts I have

Code:

x.x.x.x  webserver

in /etc/HOSTNAME

Code:

webserver

I don't know what to put in /etc/resolv.conf

any idea how to make to resolve to itself?

thanks a lot

the host command is for dns lookups only. it won't use data in /etc/hosts. so if you specifically want to resolve that data using dns then you'd need a dns server that contains that record, possibly dnsmasq. However other programs, e.g. ping use a stack as defined in /etc/nsswitch.conf to resolve names, not just dns, so maybe you're troubleshooting the wrong issue and there's no problem to addres in the first place.

but I really don't want to use DNS since it is not needed.

in that case hostname will check if the hostname is correct right?

hostname -i
