Unable to resolve hostname

[Gilberto Ferraz]

Hello, and where can I do this?

@ch3i Or make sure the DNS Resolver is a part of the named/search of the /etc/resolv.conf file.

Ok, in my debian server I have do that :

apt-get install resolvconf
vi /etc/network/interfaces

Add those lines to my interfaces file :

dns-nameserver xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy
dns-search domain1.com
dns-search domain2.com

Save file and run (it’s to update /etc/resolv.conf file):

resolvconf -u

Content of resolv.conf file :

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver xxx.xxx.xxx.xxx
nameserver yyy.yyy.yyy.yyy
search domain1.com
domain2.com

Now ping in FOG is functional.

Can you try to ping a host with shortname and FQDN like that :

ping 74_armazem

ping 74_armazem.yourdomain.com

I have a machine with attached HP35076 hostname is a machine with WIN 7 I can ping the IP of this machine. but I can not ping the hostname.

Maybe the problem is in my pfsense or own firewall Win 7.

if I can ping out of my fog to www.google.com for example the problem may be in the firewall of my machines windows 7 or even pfsense that makes the management of all of my networks.

It’s not a FW problem if you can ping the IP.
It’s a DNS problem, have you a domain ? have you a DNS server configured in your machines ? If yes provide me those informations.

[Gilberto Ferraz]

i disable FW on machine win7 and i can ping the ip address but not !

[cml]

Are your machines part of a domain? Try adding the domain to the end.

My domain is test.local in order to ping Laptop-2 I have to run:

root@Fog:~# ping Laptop-2.test.local
