Static IP is not working
"Bringing up interface eth0: Error, some other host already uses address 10.58.121.251"
But this IP is not assigned to any other machine.
The interesting thing is we are able to set this IP using a DHCP server.
Could some help me in this regard.
Thanks in advance.

Re: Static IP is not working
Is that the only interface on this system?
> [...] some other host already uses address
> 10.58.121.251"
If this system is down, can any other system
communicate with (ping, Telnet, ...)
10.58.121.251?

You know this how, exactly?

What, exactly, does this mean?
If there's a DHCP server which is handing out
this address, then how much sense does it
make for you to give it to anyone as a static
address? I thought that a DHCP server
normally used a pool of addresses which were
_not_ used as static addresses on the
network.
How many DHCP servers do you have?

That looked to me like good advice. (Better
that you thought it was, certainly.)

Re: Static IP is not working
The IP address may not be assigned, but some other machine is using it.
shut down this system go to another and try ping 10.58.121.251
Bet you get an answer.

Re: Static IP is not working
Even though I have 2 DHCP servers the hostname and IP Addresses in dhcpd.conf file is not duplicated.
