Archlinux slows down when internet cable (LAN) unplugged
Hi !
Sorry for my bad English 
Always when I unplug my RJ45 internet connection cable of my Lan card, the whole system slows down. I got a P3 700MHz and 256MB Ram.
My Desktop Environment is Gnome. I don't know where the problem is, but I think it's probably gnome.
Does anybody know this problem?
How can I solve it?
Thank you
benny

Re: Archlinux slows down when internet cable (LAN) unplugged
You could try and just stop the network deamons as soon as you unplug the cable:
/etc/rc.d/network stopOffline

Re: Archlinux slows down when internet cable (LAN) unplugged
Thank you very much. This works.
Does your code the same like ifdown on other distros?
Do you know how i can get ifup/ ifdown (in which package)?
best Regards and Thank you

Re: Archlinux slows down when internet cable (LAN) unplugged
ifconfig eth0 downdoes the same as ifdown. Replace eth0 with your network interface. Just type 'ifconfig' to display all available interfaces...

Re: Archlinux slows down when internet cable (LAN) unplugged
i would guess that something on the system is trying to use the ethernet, over and over and over, leading to slowdowns...

I had the same thought. It would be interesting to see bennym's output of "ps aux"...

ensure loopback (lo, 127.0.0.1) is enabled.

After disabling with /etc/rc.d/network stop I doubt it - stopping only eth0 would be better.
