confirming right action setting up hostname

elfoozo · 11-17-2007, 09:11 PM

Everything I've ever read says only to define 127.0.0.1 to localhost. So in mine, I've always had:

Code:

127.0.0.1     localhost

And for a host entry I'd do:

Code:

192.168.1.50     orion     orion.domain.tld

Ubuntu should grab the value for 'hostname' from what you have defined in /etc/hostname.

Might be that you have a firewall stopping your pings?
Check that with 'iptables --list'

If there's no firewall it should look something like this:

Code:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Good idea...elfoozo

Think it looks ok though:

Code:

hamster@orion:~$ sudo iptables --list
[sudo] password for hamster:
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
hamster@orion:~$

My hostname cannot be seen from other computers on the network.
ping orion on any of the networked pcs time out but they do respond to the ip 192.168.1.50. lol!

It wouldn't be to do with the fact that my gateway is high at 192.168.1.254 would it?

/etc/network/interfaces

Code:

# primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.50
gateway 192.168.1.254
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255

is your firewall set to allow pings through? I think by default most modern firewalls don't allow this as it prevents bots from easily locating a machine at your IP address. Of course the windoze machines respond... windows is inherently insecure.
