[SOLVED] netcfg "IP lease attempt failed" on ethernet connection

Since the latest update today I can't connect to the Internet (using an ethernet cable) any more.

# NETCFG_DEBUG="yes" netcfg cable
DEBUG: Loading profile cable
DEBUG: Configuring interface eth0
:: cable up                                                [BUSY]
DEBUG: status reported to profile_up as:
DEBUG: Loading profile cable
DEBUG: Configuring interface eth0
DEBUG: ethernet_iproute_up ifup
DEBUG: ethernet_up dhcpd -qL -t 30 eth0
DEBUG: 
 > DHCP IP lease attempt failes.
DEBUG: profile_up connect failed
                                                             [FAIL]

System: Arch 64

Does anyone have any idea what might be wrong? Not sure where to start there, as the interface eth0 seems to be up and all right under ifconfig.
Thanks for any hints.

ls -l /var/lib/dhcpcd/
if there is dhcpcd-eth0.lease , remove it and try again

Re: [SOLVED] netcfg "IP lease attempt failed" on ethernet connection

I would check the output of ip link and ensure that eth0 does not report "NO-CARRIER".  If it does (and even if it does not), check the activity lights at both your computer and router to ensure that your cable is connected.  Also, try a new cable.  I cannot even guess how often that fixes the issue

If you have connectivity, try putting the interface up by hand : sudo ip link set  eth0 up

If that works, then try starting dhcpcd (or dhclient) by hand and see what happens.  ( sudo dhcpcd )

Re: [SOLVED] netcfg "IP lease attempt failed" on ethernet connection

Thanks very much for your suggestions, ewaller.
Weirdly enough though, this morning I came into work, plugged in the cable and, voilà, it worked straight away.
Maybe it's just that time of the month.
Anyway, thanks again to you and cybertorture. I'll mark this as solved for now.

EDIT: Just a little follow up to make it a bit more embarassing: I just realised that it was actually the port of the switch that's broken. So thanks to ewaller for stating the obvious
