 Posted: Thu Aug 28, 2003 3:29 pm Post subject: how to automatically detect hostname on boot? |
 |
|
| I've searched the forums for 'hostname', but noone seems to have this problem. Back when I didn't know about gentoo and used Mandrake, on boot my machine would automatically detect my hostname and the login would say something like "welcome to jones-1125.jones.rice.edu" With gentoo, it seems you setup your own hostname in /etc/hostname. How can I have dhcp automatically detect my hostname (it changes every once in a while, and i need it for ssh at college)? thanks! |

Well...
hostname is your computer name.
if you set your hostname to "LulaTheBabe"
and then:
| Code: |
ping -c3 LulaTheBabe
|
then you will have a ping reply.
The hostname only works on a local Lan or if you are on the same network as the hostname.
I think you mean a "hostname" like:
0x50a06ef0.naenxx4.adsl-dhcp.tele.dk
(got that hostname from www.myip.dk)
thats your "account" on the ISP´s server right now, you get another "account" then your ip changes (or am i wrong ?)
if you have to ssh into your computer on your college, then you could get a DNS to the college´s external ip, but then port 22 have to be forwardet to your computer.

you have to set -H parameter to the dhcp on /etc/conf.d/net file.
there should be line like this
#dhcpcd_eth0=""
change it to look like this
dhcpcd_eth0="-H" |

| At least the data is in /etc/dhcpc/eth0.info (replace eth0 with whatever your network interface is called). |
