Slackware :: WEP 64-bit - DHCP Won't Assign IP
Jan 6, 2010
The router is set up to use a 64-bit WEP passphrase. From what I've read, that means four different hex keys. One of which is meant to be active. I've tried each of the four generated keys, one-by-one. I've also tried putting them all in and activating one, but the syntax seems to be wrong.
I read Alien's Wiki on it, and various other sources. People keep suggesting wicd, but I want it to work with the rc.inet1.conf file first. Just so I know what needs to be entered in order for that to happen. I have a desktop to set up eventually as well, and that shouldn't need wicd.
My configuration file*: [url]
My lspci entry for the wireless card:
Code:
*I've edited this several times since upload, but nothing has worked so I don't think I need to keep it up-to-date. The online file is basic configuration, I believe.

I noticed that my internet connection wasn't automatically brought up each time I logged into Fedora so I opened the system-config-network tool and edited my network adapter by checking the box marked "automatically start at boot/login." To my surprise, the connection went down and upon trying to click on the device to let the manager bring up the connection the greyed-out phrase "device not managed" appeared underneath the device name and wouldn't allow me to connect.
Even when I used ifconfig/dhclient to get the connection up nothing happened. I could get the router to assign an IP address through DHCP, pinged a few sites to make sure it was legit, but still couldn't use firefox to browse anything. Seems as if network manager GUI is conflicting with command line attempts to bring the network up. I'd like to permanently disable system-config-network if possible because it's acting screwy!

I'm looking for a method to assign a default gateway via dhcp randomly depending on ether the last char of the mac being odd or even, or the time the user connects. Is there a good reliable way to achieve this?

I want to setup 1Gbps our lab network and we purchased 'Buffulo Giga layer switch ' with 24ports. Is there a way to tell DHCP to assign specific IP to a particular MAC address of a machine ? We want to use DHCP and whatever the port we use ,it should have same IP ..

I have some beginner questions about DHCP, Avahi, and configuring a small home LAN.Suppose I have a dynamic IP address assigned by my ISP, which requires DHCP be enabled in my dsl modem/router/"firewall" [sic]. Suppose for simplicity I have just one PC behind the dsl modem.I think "enabling DHCP" in the modem/router means that a DHCP client runs on the router, which communicates with a DHCP server run by my ISP when I boot up a PC on my LAN. Is that guess correct? Can I get DHCP to assign a particular local IP, say 192.168.1.10 (which is not the one taken by the router--- for this discussion, let's say that is 192.168.1.0) to my PC each time I boot it up?
Now suppose I want to build a stand-alone firewall, so that my LAN will have the firewall and the first PC behind the modem, with the first PC virtually behind the firewall. By default, I think these will both have DHCP clients running which I need to configure properly. The firewall should also have a DHCP server which should control how local IP addresses are assigned, correct? I should try to arrange that the LAN has only DHCP server, only one NTP timeserver, only one DNS nameserver, correct?My first PC seems to have installed an autorun client called Avahi, which performs DNS multicast services and incorporates something called zeroconf which seems to have something to do with remote desktops, which I don't need and which is a potential security hazard. But it seems that Avahi is an intrinsic part of the KDE desktop and cannot be removed. Just want to be sure that Avahi can coexist comfortably with dhcp3-client, which is also installed on that PC. They perform different tasks, correct?If I can get the stand-alone firewall to work, I know I need to turn off the commercial firewall in the dslmodem/router/firewall device. Should I purchase a bridge and try to turn off the routing function also?

Does anyone know if you switch networks Where you have your servers hosted on a Non-DHCP Network, and you switch your IP addresses, then do you have to switch change/assign your new gateway address? I'm not sure if its manually assigned? How do you do it? Also what about nameserver resolving?

I'm currently working with wireless network kernel module.
This device initialiy gets its IP address by using DHCP,
but the problem is sometimes the new IP assigned for internal reason.
So what I want to do is assigning new(changed)IP address into exsiting
interface, or occuring DHCP renew event to cause update IP from kernel
level. This shold be done without user's intervention, so whenever the
kernel module detects IP changed(via underlying wireless
communication), it automatically correct update its IP address.
Q1) any functions or api to cause DHCP renew event from kernel level?
Q2) or any functions or api to assign IP address to specific interface?

I'm establishing a server that runs DHCP server, NAT gateway and VPN server. It have two physical interfaces, one for intranet and one for internet. The NAT gateway will give internet access for intranet. Another site will connect to this server by VPN. I need the server to assign a different subnet for that site other than the local site. Do anyone know how to config the DHCP server? Should I config the client classing, and how to do it?

Whenever I monitor my CPU's, it seems only the first is ever utilized, with the second always being at 0%.Does this mean it is not being used, or just not being reported as in use?Is there anything I could do to improve the situation if it is not being used as much as it could be?On Windows, I can assign processes to both cores, or either one. Is there a way to do something similar in Linux?

I have a home lan which has always used static IP. I now have a new modem/router which has no way to assign IP's by mac address.Is there a way to set a client up to always have the same IP when the router is assigning the IP's?

Running -current (13.37) I noticed what looks like a bug in the rc.0 and rc.6 scripts. These check for a *.pid file in /etc/dhcpc to determine whether to stop dhcpcd with a -k parameter. In fact, the pid files are written to /var/run so the scripts are looking in the wrong place.

I tried to setting a static ip from dhcp, I changed lines in /etc/rc.d rc.inet1.conf as follow:
# Config information for eth0:
#IPADDR[0]=""
IPADDR[0]="192.168.18.7"
#NETMASK[0]=""
NETMASK[0]="255.255.255.0"
#USE_DHCP[0]="yes"
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""
and then I run "/etc/rc.d/rc.inet1 restart"
after that, can't access net, and couldn't ping the gateway[192.168.18.1], I have to change it back

My ISP provides my internet via DHCP. I have a home wireless router to provide internet access, wired for my desktop machine and wireless for my laptop. My question is: Is it possible to configure the router (the Access Point) to provide internet to the desktop and the laptop via static IP? Currently I have managed to configure the internet to them via DHCP and it works. I am just curious to know whether it is possible to provide the internet for them by static IPs, given that the internet that actually goes into the Access Point (the wireless home router), is DHCP.I fiddled with this a lot yesterday, but I only managed to get a working configuraton by DHCP for both the desktop and the laptop. If I supply them with static IPs, I can only ping the Access Point, but not beyond it. So does it at all make any sense to try to configure them by static IPs, i.e. is that virtually possible?

I have a slackware server running ISC dhcpd and bind, and I want to give a dual boot XP / Ubuntu client a fixed address based on its MAC.
I added a host stanza to my server's dhcpd.conf:
Code:
I restarted bind and dhcpd, restarted the client's networking, and it still requests (and receives) its previously leased address, which is not the fixed address I want it to get. I tried dhclient -r to make the client release the old address, didn't help. On networking restart it still gets offered the old (wrong) address. Could it be that dhcpd somehow hangs on to the old lease even after the client sent a DHCPRELEASE?
How do I tell dhcpd to forget about an old lease, and how do I make dhcpd hand out the fixed address (and only that address) I specified for a given MAC, regardless of what the client requests?

I've been using wicd since starting out with 13.0 and it works flawlessly when using three different WPA wireless networks and a couple of wired networks. But, every time I get on a virgin train and try and connect to the internet via the open wireless network, wicd just hangs at the dhcp stage. If I stop wicd and edit rc.inet1.conf to contain this:

Looking at var/log/messages below, it looks like I'm not being offered a lease on this particular network. I can successfully connect to the network because iwconfig wlan0 reveals my network ssid and the access point I'm connected to. But pinging google.com gives me nothing..
Code:
root@darkstar:/# tail -f var/log/messages | grep dhcpcd

During installation I set eth0 to use dhcp to get an IP address. I then installed gnome and networkmanger which handles my interfaces and works fine. But during bootup the system pauses for 5 seconds or so while it polls for dhcp. It then times out and gives me a 169.254.xx which is then replaced when networkmanager starts up at the end of bootup.
How do I stop the polling to cut out the 5 seconds?

During Slackware 13.1 setup, I chose the hostname stella-sl2. This hostname is also the one that the system is displaying before I configured network access. After configuring wired network access to my Apple Time Capsule, my hostname suddenly changed to INTERFACE='eth0'. As a result I'm noticing some very strange things, like the login prompt which has become "INTERFACE='eth0' login: ".
After configuring wireless network access to the Time Capsule, the hostname changed to "INTERFACE='wlan0'". Note that, during boot, wlan0 is brought up AFTER eth0.
Also strange is this:
bash-4.1$ cat /etc/HOSTNAME
INTERFACE='eth0'.DNSSERVERS='10.0.1.1'
bash-4.1$ /bin/hostname
INTERFACE='wlan0'
bash-4.1$
Until now, it was only a minor annoyance, it didn't prevent anything from happening, internet connection was not affected. But now I'm configuring sendmail which needs to talk to a relay SMTP server, and sendmail "HELO"'s itself using the bogus hostname:
>>> HELO INTERFACE='wlan0'
<<< 501 HELO requires valid address
554 5.0.0 Service unavailable
Probably this is caused by the Time Capsule not adhering to standards. However, the Time Capsule's firmware is the latest version, so I cannot fix this. Is there a way to prevent dhcp from changing the hostname? How can I make sure that the hostname that I configured during setup remains active?

Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4
openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108
openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67
openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?

Currently I have my eth0 interface getting a DHCP address but at times the DHCP server will not be reachable. Sooo what I would like my server to do is if it cannot find a DHCP server assign a static address to eth0. Then start the DHCP service so it can then dish out some addresses.How can I do this? Surely it is possible

I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.
