Unable to resolve hostname

[Gilberto Ferraz]

Hello !
I use the fog1.2.0 in my work, I have inventoried nearly 200 more machines.

can upload and download images and everything works fine, I have some small problems like the image below that I’m not understand why not give the error “Unable to resolve hostname” Anyone know where is the problem?

Windows Firewall, DNS rules, anything really can cause this.

Hello Tom-Elliott!

But at least I noticed all the fog 1.2.0 capabilities work well.

If you can not resolve this problem seems the fog works 100%?

@Gilberto-Ferraz Hi, not sure but I think you have to specify DNS suffixes on your FOG server.

[Gilberto Ferraz]

Hello, and where can I do this?

[Tom Elliott]

@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.

[Gilberto Ferraz]

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
