I've been using Debian Squeeze for a few years now, no troubles connecting to a DHCP server in PPOE session... (DSL service) until this morning (11.29.10) when now I do (that is to say; browser, email prog., terminal, real player, etc., just won't connect). I can do dual boot, & so am in Windows XP at the moment.
View 12 RepliesAlright, I edited "/etc/default/isc-dhcp-server" and set "eth0" as the only thing listed for interfaces. I also have the code below in "/etc/dhcp/dhcp3/dhcpd.conf" and I even copied it to "/etc/dhcp/dhcpd.conf" for good measure, and I can't get the DHCP server to start. As an intermediate to advanced user, I am under the high assumption that it is broken since everything in the docs has been set. I have googled for two days and cannot find a fix, so before I report it as a broken package, would somebody with more experience with the package chime in?
Configuration file:

I hid my wireless setup because it contains my WiFi network info including key. This box is routing, doing DNS resolution, and firewalling just fine. I just cannot get the friggin' DHCP server to start no matter what I try.
Oh, and is it safe to delete "/etc/dhcp" or "/etc/dhcp3"? They appear to be duplicates of each other...
I have a home Debian server running, and i would like to set it up as a gateway. I have 2 networkcards in it. So internet comes from the modem and on the other card i want to setup a dhcp server and it has to share the internet. But i want it also to connect to a vpn and share the internet of the vpn.. Is that possible?

I'm no expert on DHCP. My problem is that i have a CentOS 5.5 server on which i want to install a DHCP server. I have two NICs where eth0 has access to the internet and where eth1 should act as an DHCP server.
I have installed dhcpd and this is how my dhcpd.conf file looks like.
Code:
ifconfig looks like this
Code:
When i start dhcpd on eth1 i get no error messages but when i connect any devices to eth1 they don't get any IP. I cant find anything in any logs about devices trying to get an IP address. I dont have any firewall rules in iptables.
I have a home network, with an OpenWrt router operating successfully as DHCP server (using DNSMasq). I'm planning to install LinuxMCE on my main fileserver and in order for this to properly detect devices around the home it requires that it is the DHCP server. That would be fine except that I sometimes power down the fileserver (eg. when my in-laws sleep in the spare room where the server lives) and that would leave me with no DHCP which creates problems (when my in-laws want to get their laptop connected to the internet).
One answer is to get new in-laws which would be OK except that I'm still pretty keen on my wife. Alternatively is there any way to set up a fallback DHCP server ie. the router would check if there's a functioning DHCP server on the network (ie. the fileserver) and if it gets no response it will serve DHCP addresses itself.
For changing the the mac address of my lan card( eth0) in linux fedora 9(solphur) i used this command
And i could change my mac address successfully but now i couldn't connect to my network via a dhcp server ( in configuration section of my router im going to check my new mac address (because i want to spoof) ,how i can do that?
I am trying to get my intel pro wireless 3945abg working on this Lenny installation. My progress is as follows:
No wireless & LED (on the physical switch) won't turn on
installed NdisWrapper and netw5x32 driver
installed package "firmware-iwlwifi_0.14+lenny2_all.deb"
[code]....
Still no wireless, but when DHCPDISCOVER runs at startup, it is apparently assigned an IP address using wlan0. This only happens when the cable (eth0) isn't plugged in (eth0 is set to static) which leads me to believe that the wireless really does work for DHCPDISCOVER.
What I want to know so that I can mess about with it more is how do I switch between drivers? What I have been doing here is
Code:
modprobe -r [old driver]
and then
Code:
modprobe [new driver]
I have an ubuntu 11,04 samba domain server, I want to also configure this machine to work as a dhcp server, however this have give me some issues with te windows 7 workstations, my guest is that it have something to do with the iptables because those station do join the samba domain went both server and workstation are conected to a router.
This is the script I use at boot
Code:
#FOR SHARED INTERNET
/sbin/iptables -P FORWARD ACCEPT
/sbin/iptables --table nat -A POSTROUTING -o eth2 -j MASQUERADE
[code]....
I haven't test it with windows xp station but I have use the same code in the past with no problems, and since this is my first time joining windows 7 station i belive there must be some other port that need fowarding.
I would like to connect from squeeze to my windows network. Do I need samba server, smbclient is already installed?

The upgrade actually went pretty well, except for what looks like a new "feature" to mysql-server-5.1. But I post here, because the issue seemed to be in "/etc/hosts" file. If it should really be somewhere else, feel free to move it. The problem is that I don't understand what this means. What potential problems do I have without a "127.0.1.1"? Or could this have been effected by some change to the "users" table in mysql? This mythtv server "musem" is my main machine, and is being remotely accessed by the Linux box next to my TV.

I am using Gnome and NetworkManager. The wireless key is WEP hex. It was working fine with lenny till before the upgrade. After the upgrade, the network card stopped working. So, I checked
$ lspci|grep Network

Then I reinstalled the driver with apt-get install firmware-ralink wireless-tools Then the network manager tray started working again and saw the network, but cannot connect. It was trying to connect but timed out and kept asking for the password. It is the correct password. I tried deleting the old connection and recreated a new one in the nm. But still does not work.

I wanted to setup my server as a router/gateway just for educational purposes and also when it succeeded i will keep the gateway and place it on the front line right after my modem.
My current setup as it is now :
The GATEWAY/ROUTER will be doing the main work to act as a dhcp server and firewall.
Now my setup as it is now :
So now what i ment to do was :
Let the clients connect to the gateway via ETH1 and all the stuff being router to ETH0 which is the NIC that is connected to the internet.
But now i have two huge problems :
1. The DHCP configuration seems to be fine the client machines get their ip adresses and /etc/resolve.conf looks fine to. But somehow the GATEWAY/ROUTER wont let me use the specified external DNs server so i cant do anything on these machines.
2. The firewall script [url] at line 27 should be DROP but if i use this line of code the GATEWAY/ROUTER cannot use his dns server settings so when i try to browse the internet or ping a machine outside my local network it would came up with nothing.
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?
i'm trying to configure my dhcp server but without success. i've installed dhcpd apt-get install dhcpd-server then i've added the following line to my dhcpd.conf

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
View 2 Replies View RelatedI 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.
View 4 Replies View RelatedI recently bought a used Server (FSC RX200 S4) and set it up running Debian 7. Being used to Ubuntu, that was no big deal. It works as it should out of the box. This magic computing machine has four Network cards (eth0 - eth3). Now, I want to set it up as a multi-purpose server. On the one hand, it shall provide a Apache2 webserve, a SQL Server, a File/Streaming Server and so on. I have no problems setting up these.
On the other hand, it should work as a DHCP server in my local lan with some PCs and a printer/scanner. Until now, my cheap router did that job including to connecting me to the internet. Since I can't really set up a proper firewall with that box, I want to use my server for that.
Thats's my desired setup I want to achieve:
[] Router provides internet connection to Server
--> cable goes into eth0
[] Server therefore has a internet connection
--> Some internal magic routes the internet from eth0 to eth1 (preferably as a iptables setup) and does the Firwall & DHCP Service
--> cable goes from eth1 to a switch
--> switch connects the PCs and printer
[] PCs have internet and I can use the printer
So far so good, here's what I've come up with. I installed dnsmasq and isc-dhcp-server. I got some config files for both. I got a script to set up my iptables
Iptables script:
Code: Select all#!/bin/sh
#
# rc.firewall
# firewall with iptables ... stronger version
#
FWVER=0.88s
echo -e "
Loading STRONGER rc.firewall - version $FWVER..
[CODE].....
When starting up the services, I don't see any errors. Still, it doesn't work. My Server loses its internet connection and the PCs connected to the network are unreachable.

View 4 Replies View RelatedI just put a pfSense firewall inbetween my ADSL router and my LAN. It's configured to have a cachng DNS server and a DHCP server. Among other things. For reasons beyond this post the address range served by DHCP changed from 10.0.0.x to 192.168.1.x. The new DHCP server gives 192.168.1.1 as gateway and DNS server name and not the public IP addresses of our internet provider.
After reconnecting our client machines everything worked just fine on the win-xp boxes, but the Debian Squeeze servers and Ubuntu 10.4 clients all started to get network timeouts. If I ping public websites it works but browsing to the same servers fails. Other services like POP3 and IMAP also fails. All machines use WiFi to connect and the access point is the same as before.
What could it be that make the debian boxes fail? My laptop runs squeeze too and also fails. But when connecting to various other access points at hotels and such I do not get this problem.
Another weird thing is that the debian server running virtualbox cannot do things online but the virtual windows boxes running on this machine can. Weird! Where should I start looking? How is networking/dhcp clients on Debian different from Windows XP?
I'm running gnome desktop on squeeze system. When I boot my system seems to be using my internet modem as its dhcp server. The rest of the machines on my lan are correctly using my router for that purpose. As a result, what happens then is that my debian machine frequently gets a duplicate ip address assigned to it. I would like to specify to my debian computer that I want it to use the specific fixed ip address of my router for dhcp purposes.
View 9 Replies View RelatedI have two dhcp server (dhcp3) in the same network, this network is a link layer network so every host is seen as directly connected. The two servers have debian lenny and there are near 13 AP mikrotik to give connection to the XO laptops (from the project one laptop per child). This is for two public schools (each one with one server) that are connected via a p2p connection and each one provides internet for the school and outdoor too. The servers are also file servers, proxy, etc.
Each time a laptop asks for an IP, it sends a broadcast message and this petition gets to both servers, now a days the first server that reply is the one the laptop associate with. What I want to do is, knowing the bandwith use of the ADSL, the clients connected to the server, and the cost to the AP that the laptop associate with, decide wich is the best server to be connected to. What I want to achive is to balance the load and to decide the optimum connection, because now it could happen that one server is very loaded and the other is free. I tried to run dhcp with inetd and use tcp wrappers to invoke a script to check a condition before responding and, in case to be the best server, reply to the laptop, but i couldn't get the dhcp server to respond when I run it with inetd. here is my inetd.conf
bootps dgram udp wait root /usr/sbin/tcpd dhcpd3
This dhcp server is configured with redhat enterprise edition. I found that logs are generating in the following path /var/log my doubt is how can i setup the logs generating for a specified day.
