I had installed Ubuntu 10 to my desktop computer & I want to make it as DHCP server with Router, and use it for testing. I had installed dhcp server (apt-get install dhcp3-server) what should I do further? What file to edit?Also , I had 2 network cards, so I had to assign correctly the IPs & interfaces.

However, establishing static connection is driving me batty. Will not take. I've reconfigured "interfaces" file several times. My fingers are numb ifdown-ing and ifup-ing and /etc/init.d/network restart-ing.
I have two files in /etc/network ... interfaces and interfaces~ (one static and the other dhcp). I can switch them in and out of play. The dhcp works and pings out like a champ. static is dead, just dead. Cannot ping router ... nothing.
I'm trying to make a DHCP server work on my CentOS 5.4 box, but I have placed it on another subnet than the one that it is going to serve. I use a helper address on my router to make the the DHCP requests being routed to the DHCP server on the other subnet.

The cable internet I'm using runs on Dynamic DHCP IP addresses. I changed it to a static IP address in my router settings, but it keeps changing. This means that I can't connect to my home server from a remote location.
Is there anyway to run my ubuntu server on a DHCP IP address without connecting through my router 192.168.1.xxx?
I am in the process of writing a socket program that will need to talk to different computers across the world. I want to set up a virtualized WAN on my computer so i can install the software on a virtual machine, and test it's connectivity in a "real"ish WAN environment.
[URL] Looks promising for setting up the WAN, but i was curious if anybody knew a better way to do it than setting up a bunch of virtual servers, and then another virtual server running WANEM to act as the WAN. I have never been very successful with Virtual Nic's
I would like to make my Fedora 13 box a DHCP server for my network. I can not find dhcpd in YUM. Is there a way to make my Fedora box a dhcp server? This was relay easy with Suse, but my Opensuse box just suffered a hard drive failure.

View 3 Replies View RelatedMy 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?
View 10 Replies View RelatedBack 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?

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.

I get assigned an IP from the university's server. Every now and then, a student will plug in his router to the network trying to get wifi in his/her room.
And by doing so will start assigning IPs on the network, while rendering useless the university dhcp server, which has to cope with a higher number of pc's.
How can I specify to dhclient (or the linux system in general) NOT TO obtain IP addresses given by a specific mac address ?
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!
How do i test negotiation between server and client for various protocols like:

My router is crap. If I use DHCP it sets all the computers DNS to itself and all DNS requests get cached in the router. It even starts to loose some DNS request if to many are made at once. On my windows PCs this isnt a problem I just set DNS to google's public DNS servers (8.8.8.8 & 8.8.4.4) and bypass my router and ISP alltogether but when i go to pref>network_connections i have to either set DHCP or manual, there is no option to set DHCP with custom DNS.
I'm sure there must be a way to do this in terminal, can someone tell me how?
I'm using ubuntu 10.10.
when I change the hostname on my Ubuntu server, the DHCP clients table in my router is dropped.I'm running 32-bit Ubuntu Server 10.10. My router is a Linksys WRT54GL with firmware version 4.30.15. I'm changing the hostname by modifying /etc/hosts and /etc/hostname. I've also tried changing the hostname using the Linux hostname command in a terminal, but this does not seem to behave correctly according to the manpages (it does not actually change the hostname, or update either of the aforementioned files).
I've also tried using a different router - a Linksys BEFSR41 - but the DHCP table is still dropped when I change the hostname on my server (although this router is not all that different from my other one).
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.
