Hi,

I was wondering if anybody could tell me how to bring up and down the ethernet connection from the terminal. I am receiving IP from my router, dhcp.


Thanx in advance

btw

$ sudo ifconfig en0 down - seems to work
$ sudo ifconfig en0 up - does not work

cheers

I was going to suggest using ifconfig en0 down as well but, like you, I can never get "up" to bring the interface back up. So what DO you do to bring the interface back up?

[callefoss]

Found some stuff that I have not tried yet my self, but it should work.

"sudo ipconfig set en0 DHCP" - to bring it up

Or

restarting the network interface with:

"sudo SystemStarter restart Network"

I cannot try this my self until tomorrow, so let me know if it works.

I don't believe this is limited to OS X Server... check out the "networksetup" command.

This should be:

sudo networksetup -setnetworkserviceenabled "Built-in Ethernet" on
sudo networksetup -setnetworkserviceenabled "Built-in Ethernet" off

[callefoss]

Thanxs, but the networksetup command does not seem to work with client OS, at least not for me.

Anyway, I use the command "sudo ipconfig set en0 NONE" to bring it down and "sudo ipconfig set en0 DHCP" to bring it back up again.

BTW, on my machine, it's in /usr/sbin which is in root's $PATH, but not in other users' $PATH. I also seem to recall reading somewhere else that some of these utilities are installed on OS X Client with ARD Client 2.0 (which is a free download, apparently).

Uh, /usr/sbin is in everyone's $PATH by default, I think. And it certainly isn't included with OS X Client by default, and the OS X Server version requires OS X Server. I get the following message when trying to run it:

Code:
gonzales:/Volumes/server/usr/sbin finlay$ ./networksetup 
This tool only runs on Mac OS X Server... exiting.

Crap... here I go spreading bad information again. [bad]BTW, Apple's going to ditch the G5 for the Pentium 4.[/bad]

According to macosxhints.com, this tool comes with the free Apple Remote Desktop Client.
