Cannot Kill DHCPCD

gojamiegirl · 2005-07-05 08:03:48

Hello

I just cannot figure this one out on my own, I know it's a big post, I hope I didn't confuse

My problem is that I cannot kill dhcpcd, as it seems to not be running. I don't seem to be able to release my IP address.

[jamie@beetlemeyer ~]$ sudo dhcpcd -k
Password:
**** dhcpcd: not running

It gives the same response even if I put "dhcpcd -k eth0 | wlan0"

I have a D-Link dwl-122 which connects to D-link Dl-524. I have the same problems on all my Arch machines, like my laptop, an HP ze4610us.

I can connect just fine and made a script to handle some things for me as other ways of handling Arch wireless confuse me. I included it here, just in case.

You may notice I also have problems w/ Gnome + network that I work around, I'll save that for another post

this is a router issue - if your router's DHCP leases are set to infinite/forever/a jillion days (whatever the actual setting is), then dhcp will not remain running as there is no need to refresh or free the lease... switch the lease to like 10 hours or something fairly long and it should work fine (you can also override it on dhcpcd command line with "-l <lease in seconds>" where "-l 0xffffffff" is infinite)

PS there's about 6 different wireless script implementations, and the official version is in the testing repo, which I would recommend vs writing your own implementation

Thank You Phrakture

Of course, ...you were correct. I knew it was something like that. See what happens when you don't RTFM!

I actually had my router set for 2 hr. leases because I had read this before, but *apparently* I never actually made sure it was giving 2 hour leases. The -l option on dhcpcd made it work just fine... and thanks for letting me know about the wireless scripts in testing.

No problem, always happy to help (when I'm not blathering like a fool )
