linux server system cannot resolve name, but windows system no problem?
 

Hi, in my network have windows system, linux and more... there have a DNS server.

1. When i setup a new windows xp system, i finish configure ip add,DNS... than system itself can ping other system host name, and also other system can ping this system host name.

2. When i setup a new linux server system, i finish configure ip add,DNS... than system itself can ping other system host name, but other system cannot ping this system host name?

3. but have 1 of linux server system are difference, itself can ping other system host name, and also other system can ping this system host name. Other linux server, network setting i already follow with this system but still cannot.



Thank you.

Are you defining a default gateway? Some more details would be useful. Perhaps post the contents of /etc/sysconfig/network-scripts/ifcfg-eth0 and the output from "ifconfig".

The default firewall on some systems is a pain. In order to ping to mandriva 2008 after install you have to edit shorewall.conf and open ports/allow ping and other actions before you can ping the system or get network shares to work properly.

At least this has so far been my experience.

Just an FYI, please capitalize the personal pronoun "I". You mentioned DNS. Are you referring to a DNS for the LAN or your ISP's DNS server. If the former, the read then man pages for nsswitch.conf, host.conf, and libns_dns.

Also check if your system uses the avahi daemon. You may be able to resolve an IP address like hostname.local.
How many hosts do you have? Do they have static IP addresses or do they use DHCP? If they use static address and
you have a small number of hosts, you could maintain an /etc/hosts file.
