Thread: Ubuntu 12.04 LTS DHCP only working from router not modem

alright, because didn't know begin in googlin' department decided create post it.

not new linux , think have fair understanding on unix system.

have created 2 new servers today running 12.04 lts, same hardware. using same dvd install software.

first servers worked "like boss", pugged network cable ethernet port , other in dumb switch. switch pugged router , able pull dhcp stuff modem, proceeded make them static. worked fine. , running.

here comes purpose of question... on server number 2 did same stuff did on other server, however, unable pull dhcp settings modem , here troubleshooting:

1. so unplugged 1 of other servers working , pugged in port on switch (checking if port bad)... didn't work
2. used other server's network cable (checking if cable bad)... didn't work
3. went original cable , pugged router , pulled dhcp settings

so, why cannot not pulled dhcp settings modem pull them router. disk have gotten damaged 1 disk try other one?

are hostnames different?
