Arch Linux

Hi Judd,

This has been a pickle for me for some time(see http://bbs.archlinux.org/viewtopic.php?t=1579). I'm assuming that I'm not alone in the use of a consumer-grade Wi-Fi router, here, at home. These devices seem to be preset(and some are not adjustable) to long/infinite dhcp lease-times. Apparently the 'dhcpcd' kills itself if a long/infinite lease is acquired. So, as a result, a very repremanding message is produced during ifdown() in rc.d/network when a .pid is not found. I am submitting this request as a 'cosmetic' fix, but for which I believe adds additional 'polish/professionalism' to Arch and especially to nOOb's who might be confounded by it(or worst-case ... made to feel apprehensive about the stability of other inner-workings). You'll have to evaluate my 'fix' as my 'best-guess'. It would seem to suffice, since, the '*.pid' would automatically be removed upon next boot by the ifup() earlier in the script. Please let me know if I am blundering into territory I know nothing about ... :)

(Please also consider adjsting 'dhcpcd -t 10' to 'dhcpcd -t 20'(as shown, below) for those of us using pcmcia Wi-Fi cards which need a few extra seconds to initialize during the boot sequence before being ready to acquire dhcp signal)


FIX:

ifup()
{
varname="\$${1}"
eval new_ifline=$varname
if [ "$new_ifline" = "dhcp" ]; then
# remove the .pid file if it exists
rm -f /etc/dhcpc/dhcpcd-${1}.{pid,cache} >/dev/null 2>&1
/usr/sbin/dhcpcd -t 20 -h $HOSTNAME $1
else
/sbin/ifconfig $new_ifline
fi
return $?
}

ifdown()
{
varname="\$${1}"
eval new_ifline=$varname
if [ "$new_ifline" = "dhcp" ]; then
return $?
else
/sbin/ifconfig $new_ifline down
fi
return $?
}


Thanx, Chris.
