IP Unavailable, wireless help please

i have just installed slackware 12 and compiled the latest madwifi drivers for my atheros chipset. everything seems to be in order, as i can scan for the local area wireless networks just fine, but i cannot obtain an ip address.
i have set up my wireless network info in the wireless networks config section in kde, and when i go into kwifimanager my network comes up and says im connected with good signal strength but it says ip unavailable.
i have done an ifdown on my ethernet port(eth0) and an ifup on my wireless(ath0) and i have tried dhcpcd ath0, it just stalls for about 30 seconds and nothing happens. and dhclient ath0 gives me this message:

wifi0: unknown hardware address type 801
wifi0: unknown hardware address type 801
Listening on LPF/ath0/00:15:af:09:3c:94
Sending on LPF/ath0/00:15:af:09:3c:94
Can't bind to dhcp address: Address already in use
Please make sure there is no other dhcp server
running and that there's no entry for dhcp or
bootp in /etc/inetd.conf. Also make sure you
are not running HP JetAdmin software, which
includes a bootp server.

i have googled my problem for the past hour and only find people saying the same things that arent helping me. i hope someone else has had this problem and knows how to handle it or someone might know whats wrong. i have used wireless with no problems on debian and ubuntu.

thanks.

In my experience, the KDE GUI tools don't work as expected. Maybe they are great tools, and I'm not able to use them properly.

In Slackware your network is setup in /etc/rc.d/rc.inet1.conf and /etc/resolv.conf -- and if you want to set it up automatically, rather than edit thess files, you can open a terminal/konsole and as root run the command "netconfig" which will do it automatically for you.

If you use "netconfig" and still have problems, post back and we'll go from there.

oh thanks for reply, sorry i took a nap there for a little while. lol.
ok so i ran netconfig, it didnt really offer me any options other than choosing my host name, domain name and whether i wanted to connect my ethernet port with static ip or dhcp. but no help for wireless.
thanks anyways.

ok so i tried to edit the /etc/rc.d/rc.inet1.conf file.
i found this:
# You can configure network interfaces other than eth0,eth1... by setting
# IFNAME[interface] to the interface's name. If IFNAME[interface] is unset
# or empty, it is assumed you're configuring eth<interface>.

so i tried this:

IFNAME[ath0]
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]=""

but on boot it just says command IFNAME[ath0] not found.
???

still working at it.

To answer your above post ^ before proceeding to my diatribe :}

If you want to try editing /etc/rc.d/rc.inet1.conf it should look like this:

Code:

# Config information for ath0:

IFNAME[0]="ath0"

IPADDR[0]=""

NETMASK[0]=""

USE_DHCP[0]="yes"

#DHCP_HOSTNAME[1]=""

If that doesn't work ...

First, is your wireless adapater recognized? What is the output of:

Code:

/sbin/lspci | grep -i ethernet

Second, is the module for your wireless adapter loaded? What is the output of:

Code:

lsmod | grep -i ath

Third, as asked from your system, are you running the HP JetAdmin software? What is the output of:

Code:

ps aux | grep -i hp

Fourth, what does your network setup look like? What is the output of:

Code:

cat /etc/rc.d/rc.inet1.conf

and

Code:

cat /etc/resolv.conf

Last, what is in your system log? What is the output of:

Code:

dmesg | grep -i wifi

haha...yes i figured this one out shortly after posting that, after about a minute on reboot it seemed to assign a mac address to ath0 but didnt work.

If that doesn't work ...

EDIT: i have since found this guide http://madwifi.org/wiki/UserDocs/Distro/Slackware buried in the docs at madwifi.org. its still no help as i followed it step by step and still come back to square one, so i re-edited my files back to the defaults as you see them there. if you can think of any other options i have, please let me know. :)
otherwise i am considering this a lost cause for the time being.

This is what I see wrong:

Code:

# Config information for eth0:

IPADDR[0]=""

NETMASK[0]=""

USE_DHCP[0]="yes"

DHCP_HOSTNAME[0]=""



# Config information for eth1:

IPADDR[1]=""

NETMASK[1]=""

USE_DHCP[1]=""

DHCP_HOSTNAME[1]=""



# Config information for eth2:

IPADDR[2]=""

NETMASK[2]=""

USE_DHCP[2]=""

DHCP_HOSTNAME[2]=""



# Config information for eth3:

IPADDR[3]=""

NETMASK[3]=""

USE_DHCP[3]=""

DHCP_HOSTNAME[3]=""



# Default gateway IP address:

GATEWAY=""

You have no interface for ath0, and eth0 is running.

This is how I would suggest you set it up:

Code:

# Config information for eth0:

IFNAME[0]="eth0"

IPADDR[0]=""

NETMASK[0]=""

USE_DHCP[0]="yes"

DHCP_HOSTNAME[0]=""



# Config information for ath0:

IFNAME[1]="ath0"

IPADDR[1]=""

NETMASK[1]=""

USE_DHCP[1]="yes"

DHCP_HOSTNAME[1]=""



# Default gateway IP address:

GATEWAY=""

Your output of "/sbin/lspci | grep -i ethernet" indicates you only have two ethernet interfaces, so that is all you need in that file.

You can change the file as above, save it, then restart but issue these commands:

Code:

/etc/rc.d/rc.inet1 eth0_down

which should stop your wired interface. Then issue:

Code:

/etc/rc.d/rc.inet1 ath0_restart

which should start your wireless interface.

There are ways to write scripts, etc., so that you can start the one you want at boot. But the easiest thing for now might be to just comment out (put # in front of the line) the one you don't want to use. For instance:

Code:

# Config information for eth0:

IFNAME[0]="eth0"

IPADDR[0]=""

NETMASK[0]=""

#USE_DHCP[0]="yes"

DHCP_HOSTNAME[0]=""



# Config information for ath0:

IFNAME[1]="ath0"

IPADDR[1]=""

NETMASK[1]=""

USE_DHCP[1]="yes"

DHCP_HOSTNAME[1]=""

should start the wireless interface when you boot. If you want the wired, comment ath0 and uncomment (remove the # from in front of the line) eth0.

thanks for reply.
but what you suggest is exactly what i did after i read that guide from madwifi. i think this is just slackware's way of telling me to go back to debian. lol.

Go back, but you still have incorrect information in /etc/rc.d/rc.inet1.conf ...

Garbage in, garbage out.

lol...whats the incorrect information? everything is commented out, how can it be garbage? i already told you i edited the file as you described after i found that guide. the file you are looking at was before i had done anything to it.

this is exactly how my /etc/rc.d/rc.inet1.conf file looks right now

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

# Config information for ath0:
IFNAME[1]="ath0"
IPADDR[1]=""
NETMASK[1]=""
USE_DHCP[1]="yes"
DHCP_HOSTNAME[1]=""

but im leaving the changes i made to it commented out because when i restart my card or reboot my computer dhcpcd request for ath0 takes like a minute and still doesn't get my card to work.

This info from your one of your earlier posts is part of the problem:

Code:

ath0 IEEE 802.11g ESSID:"" Nickname:"host"

Mode:Managed Frequency:2.427 GHz Access Point: Not-Associated

Until you fix that, you won't be able to get an IP address.

Disable any security on the router - WEP, WPA, MAC address filtering, etc. Make sure the SSID is broadcast. Use iwconfig to set the SSID on your card - iwconfig ath0 essid your_ssid

Look at the output of iwconfig ath0 again to make sure it's associated. If so, try dhcpcd ath0. If not, try bringing the interface up - ifconfig ath0 up.
