Debian Configuration :: DHCP For Multiple VLANs

Feb 7, 2016

I'm trying to setup a DHCP server that serves several different VLANs, we have 5 in total. Our network is working correctly, with static IPs, we're able to ping across without any issues.

When I connect my debian box to an interface on VLAN5, statically assign an address in the correct range, it works. Similarly with all other VLANs.

To configure this box as a DHCP, I set one of the ports on the switch as trunk, connect that to the debian box to allow all VLAN traffic to reach my debian box.

I setup DHCP following the steps on [URL] ....

Then I configured different VLANs by following the steps on [URL] .....

However, with the vlans setup, I am unable to ping anything. This is essentially what I did.

Code: Select allSet the port on the switch to trunk with 802.1 encapsulation
disable eth0
vconfig add eth0 5 # to add vlan 5
ifconfig eth0.5 192.168.5.254 netmask 255.255.255.0 up
vconfig add eth0 5 # to add vlan 10
ifconfig eth0.5 192.168.10.254 netmask 255.255.255.0 up

[Code] ....

I do not know why I am unable to get any connectivity through my VLAN interfaces.

Fedora Servers :: Iptables NAT To Multiple Vlans?

Mar 26, 2009

I have eth0 for administration, and vlans eth0.2 eth0.3 and br0 for resource seperation. My esternal interface is ra0.each internal interface is on a seperate subnet, and I have dhcpd giving connecting devices ip addresses out of their assigned network. I want all of the devices to be able to access the internet through NAT, I need to allow them to communicate with port 80 on eth0's subnet

eth0 10.0.0.0/24
eth0.2 10.2.0.0/24
eth0.3 10.3.0.0/24

OpenSUSE Network :: Config Files For Multiple IP's On VLANs?

Jun 10, 2011

How can you do it with individual ifcfg-* files?

I've tried adding them like this:

Filename: ifcfg-vlan1:0
BOOTPROTO='static'
ETHERDEVICE='vlan1'
STARTMODE='manual'
USERCONTROL='no'
IPADDR='192.168.1.2/24'

but it fails on ifup, thinking it might be the filename (the vlan tagging being picked up from the name) I tried renaming it but still no go.

I can add IP's via ifconfig, eg ifconfig vlan1:0 192.168.1.2 netmask 255.255.255.0 up

and I'm pretty sure I could add multiples to the ifcfg-vlan1 file but how do I add them from individual config files?

Networking :: Server On Multiple VLANs Server Not Responding To Pings From Non-local Subnets?

Jul 14, 2010

I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.

Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:

Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Debian Configuration :: DHCP And The Desktop Responsiveness?

Aug 15, 2010

I am connected to a network using any interface (eth0, eth1, or wlan0) that if my ip address was given out (dhcp) that my desktop responsiveness gets worse. Specifically the mouse has a sort of "sticky" feeling. I mean by that that I'm moving the physical mouse and the cursor is getting stuck here or there on the screen. It is extremely annoying. Here is my config file:

beethoven:~$ cat /etc/dhcp3/dhclient.conf
# Configuration file for /sbin/dhclient, which is included in Debian's
#dhcp3-client package.
#
# This is a sample configuration file for dhclient. See dhclient.conf's

Debian Configuration :: Host Name Not Broadcast To DHCP

Dec 21, 2010

I have setup a few machines within my house. The Debian Squeeze machines do not provide a host name in the DHCP client list on my router. Strangely, my Ubuntu, Android, and Blackberry machines do show host names. I have noticed the same behavior when wirelessly tethering my Debian laptop to my Android phone (which also uses DHCP). Is there something I need to enable to have the name show up on the router?

Debian Configuration :: Static IP Switching Back To DHCP

Jul 15, 2010

I'm new to the forum and actually to Debian as well. Have been running Ubuntu for the past few years. Just setup a small Dell laptop to use as a Squeezebox and Print server. It's been up 6 days without a hitch as far as serving music to the squeezebox and printing. The problem is that it loses it's static IP, so as long as I look it up and change the radio Squeezebox and printer definitions around on the clients everything keeps working.

Does anyone have any ideas?If the connection drops for some reason and the system has to re-initialize the connection, shouldn't it use the /etc/network/interfaces file and get back to the static IP that it is configured for?If anyone has any ideas of why this could be happening or have a solution, I would really appreciate the help.

Debian Configuration :: No Net After Changing DHCP Server Other OS Works?

Dec 15, 2010

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?

Debian Configuration :: Use Specific Address For Dhcp Server?

Apr 27, 2011

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.

Debian Configuration :: DHCP Server In Squeeze Appears Broken?

Dec 3, 2010

Alright, 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:
subnet 10.0.0.0 netmask 255.255.255.0 {
option domain-name-servers 10.0.0.254;
option broadcast-address 10.0.0.255;

[Code].....

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...

Debian Configuration :: Slow Boot Waiting For DHCP On Wire?

Mar 23, 2011

Up until very recently I've had a wired network, and at boot I'd see messages about DHCPREQUEST and DHCPOFFER and stuff as it set up the wired network.

Now I've just got wireless working instead, but it still tries to use DHCP on the no-longer-existing wired network. So it says "DHCPDISCOVER on eth0..." and waits for a bit, then again and waits again, and all the time the boot is waiting for a reply to its DHCP requests and it's not going to get one. It doesn't seem to do any harm, because once it's given up and proceeded with the boot then the wireless does seem to work fine, but I'd like to speed up the boot a little by cutting out this needless waiting. Has anyone got an idea how I can stop it? I tried in Preferences-Network connections and in Administration-Network, and in System Tools-Network tools, and also from the network icon in the task bar, but I can't find anything which lets me configure the wired network eth0 or disable it or disable the DHCP.

Debian Configuration :: How To Assign Specific Local IPs In Home LAN Using DHCP?

Apr 29, 2011

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?

Debian Configuration :: KVM / One Interface / Multiple IP Addresses

Dec 27, 2015

I'm renting a server which comes with 5 IP addresses, but only one network device. From what I can understand I'm able to create aliases by adding entries to /etc/networks/interfaces, I haven't tried I'm in the planning stages. Hypothetically, 192.168.22.30 is my primary IP and I want to set eth0:1 to have 192.168.22.31, and then after that I want to create a virtual machine (using kvm/qemu) that is able to communicate bidirectionally to the internet over eth0:1, and leave eth0 strictly for administrating (not for VM traffic).

The qemu guides I'm finding seem to assume that I want to use TAP or VDE, what I want to use is a sub-ip/alias. One guide I saw had me eliminate everything from eth0 and put it under br0. That would leave me unable to ssh into my server (and unable to administrate). Is there a way I can do something along the lines of: qemu [options] -net [option] -netdev=eth0:1 ?

Debian Configuration :: Correct Way To Start Multiple Instances Of MPD?

Mar 18, 2010

The first thing that comes to my mind is to add (copy) the script in /etc/init.d and the /etc/rc* directories by hand. Debian's automatic handling of init scripts on package install/removal is quite nice, so I tend to shy away from making any manual changes if there's an automated way to do it. Which leads me to the question: is there an official way to run a second instance of a daemon? (Tried google, didn't find much more than a bug report).

Debian Configuration :: Multiple Network Interfaces With VirtualBox?

Mar 29, 2010

I have a rather urgent problem with my network, I got two virtual network interfaces one internal and one external. The problem is; I can't get connection to internet. The external NIC is set as a NAT and the internal is... internal.

iface eth1 inet static
address         192.168.1.200
netmask         255.255.255.0                             

Running with this configuration makes my internet connect go away, however if I remove the configuration for eth1 everything is working fine.
