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.
Im using xfce desktop environment in debian. I find that I can not see the desktop when using Ctrl+Alt+Tab to switch window focus. I modified /usr/share/xfce-mcs-plugins/shortcuts/defaults.xml and added Ctrl+Alt+Tab shortcut to trigger a terminal command "wmctrl -k on", then i could see the desktop, but failed to switch window focus. Also, I failed to solve this problem by editing /usr/share/themes/Default/xfwm4/keythemerc Could anybody tell me a solution that you should be able to see the desktop when switching window focus, just like in win7?
Our network uses static ip's and I cannot get them to work with Debian live. In fact, when I reboot, it always goes back to "roaming". What am I doing wrong here?
I upgraded a wheezy box in qemu to jessie (without systemd!) and now I didn't get an output from the console to a hostterminal using curses.System and grub starts with terminal output, but after around 6 to 8 lines of output the terminal gets black. As far as I found out it seems that the init process switches to graphical output. I tried out all found kernel options from nomodeset up to nofb,Are their other options to stop switching to framebuffer and graphical mode.
I moved to static Ip method for my laptop. I edited the interfaces file and it seems to work since I am writing this message from that laptop, but I have a new problem with my Debian. The mounts are not mounted during the startup anymore. Before I was using the network manager method and the nerwork mounts were all fine. Now with this method, they are not mounted and I need to mount them by firing "sudo mount -a" manually.
I installed Lenny for my new server and set a static IP the usual way:
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface
My os is debian 5.0, netcard is RTL8168D/8111D. I can't use the Static ip, if I setup static ip, output "not found network device", but the network driver have loaded and if I use DHCP mode everything is ok. do you understand my english? What my next steps should be?
I have a Dell PowerEdge SC430, Squeeze 6.0.2 box, Broadcom NetXtreme NIC which works fine DHCP. The network-manager package is not installed. I have now reconfigured /etc/network/interfaces for a static IP:
auto eth0 iface eth0 inet static address 192.168.1.2
(Cross posting this from[URL]I am running an Ubuntu 10.04 server installation and I recently had to switch it from DHCP to static ip. I edited /etc/network/interfaces file and switched
"iface eth0 inet dhcp" to "iface eth0 inet static
[code]....
You'll notice the IPs are a little strange. This is because the sever is now on a special subnet dedicated to isolating specific servers. I also edited the resolv.conf file to include the proper DNS servers (including one of Google's just in case all hell broke lose).The problem is that, seemingly randomly, the machine will lose the ability to talk to the outside world. I know the machine is still up, but it acts like it has no networking at all.
I think part of the issue is that there is no DHCP running to this subnet (nor will there be) and the dhclient seems to still be running on occasion which causes some sort of conflict (no idea what) which causes networking to die. I cannot, however, remove the dhcp3-client package as it also causes the ubuntu-minimal package to be removed and that would be bad.
I need to shear internet i use isc-dhcp-serve and it work but internet doesn't work i have triad so many commends but still networking ... My setting is eth0 - wan eth1 -local
When I stop/start vm(not restart), dhclient becomes up and ip is assigned by dhcp. Why? -------------------------------- yoshi@vbox:~$ uname -a Linux vbox 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux -------------------------------- yoshi@vbox:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).
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.
using Debian 5.0, GNOME desktop.my DSL service was to be connected today.the problem is my DSL light keeps blinking.ethernet light is solid.how do i setup my DHCP on my computer
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
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?
I use a static compiled kernel and a fully encrypted disk apart from a boot partition. I have recompiled and installed kernels many times. When I tried with the latest kernel from Testing, 4.2.6, the system will not boot. Not only that but the previous kernel now does not boot. However, a stock modular kernel does boot. The static kernel hangs at:
Code: Select allVolume group "dk" not found Cannot process volume group dk /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning. Reading all physical volumes. This may take a while... /run/lvm/lvmetad.socket: connect failed: No such file or directory
[Code] ....
And after giving the password the boot continues successfully. How to diagnose it further?
Setup a DNS/DHCP/Directory server on Debian? I would like to configure the things in Debian so that can join Linux and Windows(if possible as m not sure yet) clients to the directory server. Any links to setup both Forward and Reverse lookup zone in the environment.
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.
I am using a 3rd party kernel driver that does not support udev properly. When I was using wheezy I placed the required device files in /lib/udev/devices.
The udev in jessie does not appear to support this. Is there any way to have udev create these device files or will I have to create then using a script at boot-up?
Debian Testing host, Winduhs XP guest. Winduhs is not allowed to directly access The Internets, and I am not setting up bridging as that makes it possible for the guest to mount layer 2 attacks on the LAN. I need for the guest to tunnel through the host without being able to see anything on the host, so it can then get access to The Internets, while being protected by iptables (Shorewall).
Used to be with VMware I had host-only set and the guest in a different class c (192.168.2.1) from the host (192.168.1.1) I turned on ipforwarding, set Shorewall rules, and it all worked. Now I have everything set with VirtualBox, and it does not work. Guest can ping its interface but not host. Host can ping vboxnet0. Host is supposed to masquerade guest's 192.168.2.1 through to the default out at 192.168.1.1, but it's not. I think a clue is in routing, but I don't know what's wrong.
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?
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...
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.
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?
