 |
|
my hostname is set
| Quote: |
mark@lightning ~/Downloads $ cat /etc/conf.d/hostname
# Set to the hostname of this machine
hostname="lightning"
mark@lightning ~/Downloads $ hostname
lightning
|
but i can't ping that hostname:
| Quote: |
mark@lightning ~/Downloads $ ping lightning
ping: unknown host lightning
|
my ip address is obtained from dhcp from my wifi router, so it can change. id' rather not put something into /etc/hosts to hack it to work temporarially. how do i get this hostname recognized? |

This is completely dependent on your router's DHCP/DNS caching server... The most that your Linux box can do is make sure that your DHCP client sends out a name along with the DHCP request, and if the router DHCP/DNS server doesn't honor it, you're SOL and need to find another solution.

| Yeah, export to DNS, a line in /etc/hosts, and finaly avahi (distributed, multicast DNS). 3 ways to get it done, which one is good for you depends completly on your setup |

| thanks for the insights. i ended up going with a "static" ip address from the router (dhcp server) and putting it into /etc/hosts. |
