View 3 Replies View RelatedI 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 3 Replies View RelatedThis is probably an odd request, but figured I'd ask in case someone knew. We have a lab that has the IP range 172.10.0.0/16 (255.255.0.0). The lab gateway/DHCP assigns an IP in the range of 172.10.0.2-172.10.0.254. I want to set up my own DHCP server on a specific range, for example 172.10.10.1-172.10.10.254. I create a new host fine, but since it's set for DHCP, it uses the DHCP server at 172.10.0.1. Is there a way to force it to use a different DHCP server on the client side? I realize that I can work around this with exclusions on the 172.10.0.1 DHCP server, or use iptables to deny DHCP requests to specific MACs, but wanted to know if there was an (easier?) way to configure the client to use the 172.10.10.1 DHCP server instead of the 172.10.0.1 server?

i already have an eth0 configured to automatically get its info from dhcp.
but i wanna configure eth1 to be able to serve dhcp and dns. i havent configured either dns or dhcp server on the server box since i have not configured the serving interface.
so far my interfaces file is:
Code:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp

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'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 Replies View RelatedCurrently 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 RelatedIn a previous post I mentioned I planned to buy a Canopus ADVC 55 VHS to DV capture card (viewtopic.php?f=7&t=48224).
Now I have done that. And, it works like a charm using my 64-bit Debian Sid and Kdenlive! All my VHS will be saved for the future!A short HowTo: Plug in a SCART to composite adapter into the "TV out" on the VHS player. Plug in the three red/white/yellow composite RCA cables into the adapter and into Canopus ADVC 55.
Plug in a Firewire cable into the Canopus ADVC 55 and your Firewire card on your computer. Start the computer, start Kdenlive and click the connect button. Start the VHS player and click Play.
In Kdenlive and click the Record button, as fast as you can. Wait until tape is finished. Now you have a dv-file which is about 13GB per hour, so make sure you have the space on the hard drive. The dv file should then be stored as such, as the master backup. But, it is now easily converted to any other format.
I have too many home made movies to let them rot away as VHS. My previous attempt with the USB dongle only produces precompressed MPEG2 files which would have sucked. These DV files are uncompressed, take up a huge space, cannot be played as such, but! They are the raw material for any other format. If I'd like, can using Kdenlive readily make it FullHD with a few clicks.
Oh, and it works with vinyl records too!!! Then just use Audacity to edit them later. Don't buy a cheap USB dongle, buy a Canopus ADVC 55 or something similar. The quality is crisp!!!
I 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.
I 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.
