quick inet reset

pickarooney

My internet connection goes down every night if I have a certain application running when my dynmaic Ip address is reassigned. Unfortunate enough, but not an issue.
I'm looking for a quick way to reset the connection without either rebooting or re-running the mandrake internet connection wizard, which makes me feel all inadequate as well as taking far too much time.

ifconfig eth0 down and ifconfig eth0 up don't do the trick.

Is there something along the lines of release/renew I can type, or even a few commands I can throw into a script to reset the connection quickly?

Hi,
how are you connecting to the internet?
Who is reassigning your IP?
What is the application (if you can say)?
Are you runnning a firewall?
Do you know which one?

If you're running mandrake and the interface
is normally configured for DHCP, you'll find
that ifdown eth0 and ifup eth0
will probably be closer to what you are trying to do.

You shouldn't have to rerun the connection wizard!
Pass on a few details and we'll get it automated.

If you're running a firewall, it's just possible that your
connection is still up but your new IP address is forbidden
from using it.
Reinitialising the firewall in this case would be the better way to go.

Hope that gets you closer,
NiallB.

killall dhcpcd && ifconfig eth0 0.0.0.0 && dhcpcd eth0

Anything that begins will killall has got to be good! Will try it tomorrow morning, assuming it goes down again.

I don't have a firewall, and I don't quite know how ip addresses are reassigned, but it happens in the dead of night.

I'm connecting via a cable modem (realtek 8139 ethernet card).
The application is bittorrent, which is designed in such a way as to hog every last bit of available upload bandwidth. I think it interferes with whatever sorcery retrieves the new IP address each night, so my old IP address is no longer valid and no new one is assigned.

Easy enough to find out, by running ifconfig at night and again the next morning, see if the address is the same.

Then just find out what time it goes down and at/cronjob the dhcpcd command.

Mos' likely.

Thanks for the hints, lads.

Your cable provider will assign an ip to your ethernet card via dhcp.[1]

So most likely this ip is being refreshed on you and it's buggering your download.

I'm thinking there's sfa you can do about that from the client side.

You should probably start a download just 'after' you get an ip... and then be prepaired for your isp to bugger that ip at a specified time each night. again ==>[1]

[1]I'm guessing.

Bit OT but:

If oyu think killall is good, try kill -9 "PID" against a remote user

The downloads will resume themselves like zombies once they get some IP flesh.
I think.
They're nice that way.

As you're using mandrake, you won't find a dhcpcd running.
Mandrake uses dhclient instead. Careful about running it
without arguments though. If you're running X, it can lock
your session up completely.

Just found that out ifup worked a treat though
