Changing from Static IP to DHCP without rebooting

[Krazy]

Hi,

This is not a problem, but rather a mini-hint for other newbies like myself.

If you've accidentally started Gentoox without a network connection, then it defaults to 192.168.1.13. Assuming you can login via the console (USB keyboard), then you might want to change your IP address to one issued by your (external) DHCP server instead. This may be useful if the rest of your network doesn't live in 192.168.1.x range.

I've figured out to do this without rebooting.

First pause your networking on eth0 [normal ethernet connection]:

Code: Select all

/etc/init.d/net.eth0 pause

This avoids stopping all services that rely on networking being available.

ifconfig will then show only lo [loopback]

Then start networking again with:

Code: Select all

/etc/init.d/net.eth0 start

ifconfig should then confirm eth0 is available with a IP address allocated by your DHCP server.


The only issue that I know of is that the temporary file created while booting [/tmp/eth0.addr] is not updated; it retains the same network information as displayed at the end of the normal boot process

Any comments, or other issues that I might have overlooked?
