 Posted: Wed Jun 26, 2002 4:44 pm Post subject: dhcpcd problem again |
 |
|
I have been trying to get Gentoo set up on my box and so far, things look promising. However, whenever I reboot dhcp does not come up.
I have uncommented the line in /etc/conf.d/net "iface_eth0=dhcp" however I did not edit the following line "dhcpcd_eth0="..." . Is that the problem??? Once I reboot and run "dhcpcd eth0" the connection is recognized/made. But if I do a "rc-update add net.eth0 default" I get a message saying it's all there-but then its gone on reboot.
Any suggestions??

My dhcpcd_eth0= line is commented out and mine works fine. Here's the start() section of my net.eth0... | Code: | start() {
checkconfig || return 1
local iface_args="$(eval echo \$\{iface_${IFACE}\})"
local dhcp_args="$(eval echo \$\{dhcpcd_${IFACE}\})"
local retval=0
ebegin "Bringing ${IFACE} up"
if [ "$(eval echo \$\{iface_${IFACE}\})" != "dhcp" ]
then
/sbin/ifconfig ${IFACE} ${iface_args} >/dev/null || {
retval=$?
eend ${retval} "Failed to bring ${IFACE} up"
return ${retval}
}
else
/sbin/dhcpcd ${dhcp_args} ${IFACE} >/dev/null || {
retval=$?
eend ${retval} "Failed to bring ${IFACE} up"
return ${retval}
}
fi
eend 0
if [ -n "$(eval echo \$\{alias_${IFACE}\})" ]
then
local x=""
local num=0
local aliasbcast=""
local aliasnmask=""
if [ -n "`eval echo \$\{broadcast_${IFACE}\}`" ]
then
aliasbcast="broadcast `eval echo \$\{broadcast_${IFACE}\}`"
fi
if [ -n "`eval echo \$\{netmask_${IFACE}\}`" ]
then
aliasnmask="netmask `eval echo \$\{netmask_${IFACE}\}`"
fi
ebegin " Adding aliases"
for x in $(eval echo \$\{alias_${IFACE}\})
do
ebegin " ${IFACE}:${num}"
/sbin/ifconfig ${IFACE}:${num} ${x} \
${aliasbcast} ${aliasnmask} >/dev/null
num=$((num + 1))
eend 0
done
save_options "alias" "$(eval echo \$\{alias_${IFACE}\})"
fi
if [ -n "${gateway}" ] && [ "${gateway%/*}" = "${IFACE}" ]
then
ebegin " Setting default gateway"
/sbin/route add default gw ${gateway#*/} dev ${gateway%/*} \
netmask 0.0.0.0 metric 1 >/dev/null || {
local error=$?
ifconfig ${IFACE} down &>/dev/null
eend ${error} "Failed to bring ${IFACE} up"
return ${error}
}
eend 0
fi
#enabling rp_filter causes wacky packets to be auto-dropped by
#the kernel
if [ -e /proc/sys/net/ipv4/conf/${IFACE}/rp_filter ]
then
echo 1 > /proc/sys/net/ipv4/conf/${IFACE}/rp_filter
fi

Maybe something is missing in yours?

iface_eth0="dhcp" should set the interface to use dhcp. The other option dhcpcd_eth0="" is for passing additional commands to dhcpcd. So, I would say that you probably wouldn't need to do anything special.
Try running 'dhcpcd eth0' and see if it's able to pick up an IP address (using ifconfig). If you're not getting an address, I would check to ensure that the nic driver is compiled into the kernel.
Here's what my /etc/conf.d/net looks like, dhcp seems to work fine after I added it to the default runlevel.:
# Global config file for net.* rc-scripts
# This is basically the ifconfig argument without the ifconfig $iface
#
#
iface_eth0="192.168.0.2 broadcast 192.168.0.255 netmask 255.255.255.0"
#iface_eth1="207.170.82.202 broadcast 207.0.255.255 netmask 255.255.0.0"
# For DHCP set iface_eth? to "dhcp"
# For passing options to dhcpcd use dhcpcd_eth?
#
iface_eth0="dhcp"
#dhcpcd_eth0="..."
# For adding aliases to a interface
#
alias_eth0="192.168.1.3 192.168.1.4"
# For setting the default gateway
#
#gateway="eth0/192.168.0.1" |

Nope... has to be set for dhcp to work.

i had this same problem when i installed gentoo on my other computer just now and it turns out it was a small oversight on my part.
at first i hadnt loaded the tulip module so i fixed that. then it turns out that i forgot to uncomment the iface_eth0="etc.etc.etc." line in /etc/make.conf. here's what YOURS should look like:
| Code: | # For DHCP set iface_eth? to "dhcp"
# For passing options to dhcpcd use dhcpcd_eth?
#
iface_eth0="dhcp"
# dhcpcd_eth0="..." |
the iface line should be UNcommented while the dhcpcd line should be COMMENTED.
just for shits and giggles, go ahead and do:
| Code: | | rc-update add net.eth0 default |
dont know if it'll matter or not, but couldnt hurt  then go ahead and reboot and see what happens. quick test:
if you get a reply, then yer all set 
EDIT: dunno how knowledgable you are in linux, but the ping wont ever stop like in windows. you'll have to hit ctrl-c to stop it not to insult you or anything, just that ive been working tech support for too long and it's my job to assume that everyone's technically uninitiated  if you already knew that, kudos! pay no attention to me

Can't hurt to double check, but he did post that he had tried these steps.

very true, but he stated that he uncommented the line "iface_eth0=dhcp" not what's actually there, which is iface_eth0="dhcp". he may have been calling it from memory, he may not have been. i dunno. i'm a heckler for semantics tho and sometimes it's notta good thing. figured i'd go ahead and clarify anyways.
if he uncommented that line like he says he did, then really there's no reason for it to not work unless he tinkered with the any other files (especially if he can execute dhcpcd eth0 without a hitch) - but he didnt mention that so i assumed he didnt. the only thing that leaves is what's in /etc/make.conf.
which is why i posted what i did. didn't mean to be redundant

bahh, bloody netscape 4.7.
dunno if my other post is really here or not. basically, what i meant was to clarify on something. i didnt mean to appear redundant. tho it seems that i did and i apologize.
sorry bout that wont let it happen again

No probs with me... thats why I said it doesn't hurt to double check. I have a tendancy
to assume "things in quotes" are different than quoting just the dhcp word. Probably a
bad habbit on my part. Thats why I try to use the quote or code features for posting.
