LAN K.O. on slack 10.2

gusgoose_it · 01-22-2006, 05:03 PM

newbie on slackware, I installed 10.2 on my PC with dual OS, with Win XP. My PC is on a LAN, connected with a eth0 ADSL router. While windows are able to connect with internet, slack are not. I configured LAN card with netconfig as static IP or DHCP without results. Can you help me? thanks from italy.
I enclose some info and netstat -rn, lspci, ifconfig -a.

LAN card> Realtek RTL 8139
Router> Hamlet wireless ADSL broadband router with 4-port switch firewall built-in

your interface hasn't received it's address yet...

- did you reboot the PC after setting the card to DHCP??

- do you have the package dhcpcd installed??

- did you uncomment the line for the module in your /etc/rc.d/rc.modules file??? it should look like:

Code:

/sbin/modprobe 8139too

- what does your /etc/rc.d/rc.inet1.conf file look like??

gusgoose_it · 01-23-2006, 05:39 PM

thanks Win32SUX
1) I have installed the package DHCPCD (I have controlled with pkgtool)
2) I rebooted the PC after setting the card to DHCP
3) I decommented now the line indicated, that is "/sbin/modprobe 8139too"
4) "/etc/rc.d/rc.inet1.conf" looks like:

# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]=""

# Config information for eth1:

# Config information for eth2:

# Config information for eth3:

# Default gateway IP address:

Try adding the IP address of your router here. Then run the rc.inet1 script again.

win32sux · 01-23-2006, 07:39 PM

woodsman, wouldn't having to input IP configuration details like that kinda defeat the purpose of DHCP??

gusgoose_it, did you get it to work?? your last post doesn't really say wether you got it working or not...

gusgoose_it · 01-24-2006, 03:53 AM

I put the IP address on "GATEWAY" and run the script again without result,
it doesnt work
The incredible thing is that before slack I had in the same partition SuSE 10 and it worked

Alien Bob · 01-24-2006, 04:24 AM

The GATEWAY="" shoud remain empty when you use USE_DHCP="yes".
gusgoose_it, can you paste the results of "lsmod" command? As win32sux pointed out, the 8139too is most probably the correct driver, and you might have the wrong one (8139cp) loaded by hotplug. Or vice versa!
You should try out both drivers (8139too and 8139cp). Like with these commands in case 8139cp is loaded

Code:

# lsmod |grep 8139
# modprobe -r 8139cp
# modprobe 8139too
# ifconfig -a
# /etc/rc.d/rc.inet1 eth0_start
# ifconfig
# route -n

alien bob, I put empty GATEWAY=**, as you wrote, now I post the result of "lsmod". I tried out both drivers (8139too and 8139cp), without results

you don't have iptables filtering out the DHCP packets, right??

what do your main chains look like??

Code:

iptables -L

also, as a test, give your eth0 a static IP and see if you can ping it locally (this will let us know the driver is working and stuff) - as well as remotely also...

Code:

ifconfig eth0 inet 192.168.1.1 netmask 255.255.255.0

ping -c5 192.168.1.1

okay, we can rule-out a module problem... your card is up and responding... so the focus now needs to go to the dhcpcd daemon itself... when the machine boots, are you able to see the dhcpcd try to get an IP?? is there any record in your logs of the dhcpcd trying to run?? reboot and then post the output of this (you'll need to be root):

Code:

cat /var/log/messages | grep dhcp | tail

also, see if the dhcpcd is actually running:

Code:

ps aux | grep dhcpcd

kriton12 · 01-25-2006, 12:27 PM

why not try to run dhcpcd manually?
as root:

#ifconfig eth0 up
#dhcpcd eth0

then look at the results from:
#ifconfig

to see if you have an IP address. If that gets it up and running, then dhcpcd isn't being run at the proper time.

win32sux · 01-25-2006, 12:47 PM

that's a good idea. you'll be able to see any error message that dhcpcd spits out and stuff, if any. i do have a feeling that, like you say, it's not getting run at startup time cuz if it were and it couldn't find a dhcp server, there would be this huge pause for like almost a minute during startup.

gusgoose_it · 01-25-2006, 02:25 PM

to win32sux: when the machine boots, I see

Quote:

dhcpcd : MAC address = 00:e0:4c:69:28:e5

after it, a long minute runs without any other message

okay so dhcpcd is trying to reach the DHCP server but it isn't getting a reply for some reason...

i've heard of some DHCP servers that require the host to specify a hostname when querying the dhcp server... check in your windoze install to see if it's doing that... if your windoze is indeed specifying a hostname, then insert that hostname into your /etc/rc.d/rc.inet1.conf file in the DHCP_HOSTNAME[0]="" part and reboot or re-run the network scripts...

also, if you can, see if it works if you boot a linux live cd, such as DSL, for example...
