Não consigo pingar nenhum Host pelo nome

Boa Tarde galera,

Estou usando o Ubuntu 11.04 e não consigo pingar no terminal nenhum host interno da minha rede, por exemplo:

tenho dois servidores, um se chama "linux" e o outro "server" não consigo pinga-los nem acessar um sistema em java que se encontra em um dos servidores. Para eu acessar este por exemplo, preciso ir no arquivo HOSTS e apontar o ip 192.168.0.5 ao host LINUX, dai funciona o ping.....

engraçado que no GUI se dou um Control+L e digito smb://server(ou linux) ele acha meu compartilhamento....


Ja tentei um monte de coisa e não consigo pingar os host internos pelo nome
Lembrando que pelo IP funciona normal...

Se alguem puder me ajudar agradeço!

Valeu!

para resolver nomes precisa de servidor DNS. no caso smb://server o cliente samba usa resolução de nomes NetBios

os samba esta com netbios configurado no conf

AS MAQUINAS WINDOWS PINGAM POR HOST NORMALMENTE, somente eu uso linux (alem dos servers).

Quando ao servidor DNS, creio que esta configurado. Tenho um servidor DHCP Básico configurado em minha rede com definições de DNS, vejam se está correto e o que é preciso para conseguir pingar por host apartir do meu ubuntu 11.04 (desktop)

dhcpd.conf:

#deny unknown-clients;
ddns-update-style none;
default-lease-time 600;
max-lease-time 7200;
authoritative;
