Debian Installation :: Xen Domu Creation With Nfs Static Address Boots On Dhcp
Dec 11, 2014
I am create Xen virtual machines.
I created a domu.cfg file with:
xen-create-nfs --ip 192.168.13.2 --broadcast 192.168.13.255 --gateway 192.168.13.1 --netmask 255.255.255.0 --nameserver 192.168.13.1 --initrd /boot/initrd.img-3.18.0 --kernel /boot/vmlinuz-3.18.0 --memory 4096M --mac 00:16:3e:01:01:01 --nfs_server myserver --nfs_root /var/exports/myhost --hostname myhost
I initialized it with:
xt-install-image --cache yes --dist wheezy --apt_proxy http://192.168.13.1:3142/ --mirror http://ftp.fr.debian.org/debian/ --location /var/exports/myhost
Then I started the domu with:
xl create /etc/xen/domu.cfg -c
And I receive this message telling me dhcp is used as I specified static ip:
IP-Config: eth0 hardware address 00:16:3e:01:01:01 mtu 1500 DHCP RARP
What can I do to desactivate the dhcp client?
remark: I used this equivalent former configuration with qemu-kvm and I booted with static ip without any problem.

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:

Can't change from dhcp to static ip address.I've installed Oracle's version of Linux Redhat 5, but I'm having no success changing from dhcp to a static IP address. My machine is plugged directly into a Belkin router which has the IP address: 192.168.2.1.If I use the gui: /usr/bin/system-config-network and set the network device to dhcp,it works fine. But if I set the IP address manually, I get no internet traffic, and if I ping an internet website, "network unreachable".The installation instructions for Oracle say that they want a full domainname. I've tried gateway.2wire.net. This worked in the last place I did a successful installation.It was the address of my ATT router. If I plunked that into a browser, I got the router configuration.

I have an Ubuntu Server 10.04.1 that I have given a static IP address. Every six hours or so I will lose connectivity to it and when I type ifconfig to look at the network information, it has been given an address via dhcp. If I run the /etc/init.d/networking restart command the IP address goes back to my static address and things are fine for another 6 hours or so. Here is what is in my interfaces file:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.60.82.15
netmask 255.255.0.0
broadcast 10.60.255.255
gateway 10.60.254.254
This machine is also a DHCP server and I checked to make sure there are no other DHCP servers on my network. Right now my fix is to have a Cron job running that runs the reset command every 5 hours, but I would like to find a more permanent solution.

I am struggling with what might be a minor problem. I have a home computer which I would like to setup as a webserver and hence give it a static IP address. It is connected to by wire to a router that is connected to the WAN via PPPOE. If I enable the network card on DHCP it works fine in browsing the web. If I now set it to static IP address it does not brown. Essentially I use the command setup to run the static IP setup. I then set my IP address to 192.168.254.X , the subnet mask 255.255.255.0 and the default gateway to 192.168.254.1 (this is the router connected to the WAN). I am able to ping the router, however when I try and browse on static it does not work. Your help will be most appreciated as this has taken way too long to solve and I have Googled as much without success.

I got this setup:
- Asus M2N32, Athlon X2, 4G Ram, Raid 5
- dom0 on lvm, boots always
- tried to create a domU using dirinstall
- creating a volume lamp in group VGsys with 5G and ext4
- mount /dev/VGsys/lamp /var/tmp/dirinstall
- yast dirinstall: fails when calling dirinstall_finish
- tried to create a domU using vm-install
- creating a volume lamp2 in group VGsys with 5G and ext4
- vm-install fails too
- tried to make an image on susestudio, successfully, but that does not boot, failing when trying to mount the rood partition
- copied the dom0 image to a domU disk
None of these domU booted sucessfully, all of them showed the following messages:
- kernels used 2.6.31.8 and kotd 2.6.31.12 give same results
I am told to disable scsi subsystem in the kernel, I have compiled a kernel before, but
1) I cannot believe I am the only one having this issue or I miss something truely obvious (then what do I miss, please?)
2) dirinstall and vm-install worked in 11.1, there were issues, but recoverable, why now not in 11.2?

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.

I have a Debian VM on Windows that is not getting an IP address assigned by the DHCP. I tried, ifdown eth0 and then ifup eth0 and still no IP address. my interfaces file looks like this:

# The loopback network interface

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'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 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?

This one has been bugging me for some time now. The network interface (as defined in Debian's /etc/network/interfaces file) fails to obtain an IP address from myuter. However dhclient br0 does.I'm using br0 since I run a XP virtual machine.network/interface changes are from a Debian howto on setting up the tap interface.As near as I can tell, the /etc/init.d/networking script basically calls /sbin/ifup -a. ifup is a binary.My /etc/network/interfaces file is:
auto lo
iface lo inet loopback
address 127.0.0.1

I got this message on Friday from just one domain. uote:mailsrv.forthnet.gr #<mailsrv.forthnet.gr #5.5.0 smtp; 554 5.5.0 Your message was considered to be spam by the FORTHnet Antispamming Policy and was not delivered to the recipient. The following spam tests returned positive for this message:FORGED_RCVD_HELO,RCVD_IN_BRBL. For further information visitWe are not a spamming community but it seems we have a statice IP address that has a Reverse lookup to "myipaddress.static.lyse.net" and not my email domain. Would setting a cname mail.mydomain.no -> myipaddress.static.lyse.net cure this problem or are there more tricks to be performedOnce I have cured the FORGED_RCVD_HELO I can move to getting the IP removed from BARACUDA.

I'm running Ubuntu 10.10 and I'm having problems trying to assign it a static IP address. No matter what I put in the Preferences->Networking area (identifying the interface as Manual)... it still will query DHCP for an address if I run the dhclient command. I'm using to using ubuntu server where I just set the IP in the interfaces config file.

I am trying to design an application which violates the DHCP. Specifically the difficulty in writing this application is physically sending the raw packet. I need some documentation on either a library that supports this or where to look for support for raw packet creation. I am not trying to create a raw datagram, that doesn't meet my needs because a raw datagram is still at layer 3 I need to craft a raw layer 2 PDU.
Specifically I want to
Send a very specific DHCPDISCOVER
Receive a DHCPOFFER
and pull apart the offer while never sending a DHCPREQUEST.
Specifically I am pulling apart various options that are sent in the DHCPOFFER. I have a raw DHCPDISCOVER already crafted and the formatted struct sockaddr_ll where I fault is I can't send the damn thing. Getting the file descriptor after calling socket is okay but what now? How would I write to that file descriptor and have it transmit?
Code:
int connfd;
struct sockaddr_ll bcast;
bcast.sll_family = PF_PACKET;
...
connfd = socket(PF_PACKET,SOCK_RAW,0);
//now what

Recently, I have encountered a problem when setting my network configuration.I want to automatically get an IP address through DHCP at system startup, and this can be done by editing /etc/network/interfaces file, adding
auto eth0
iface eth0 inet dhcp
The problem is that I want to set a static DNS, but DHCP will automatically overwritten /etc/resolv.conf file.
What should I do?

I have a MB with 2 NICs and on 1 I would like to have a static IP, on the other a DHCP for a local network.The problem is the DHCP provided gateway is made default vs the one for the static IP and resolv.conf is overwritten.Any suggestions how could this be resolved? I can tweak both the DHCP server settings and the box settings.

I tried to setting a static ip from dhcp, I changed lines in /etc/rc.d rc.inet1.conf as follow:
# Config information for eth0:
#IPADDR[0]=""
IPADDR[0]="192.168.18.7"
#NETMASK[0]=""
NETMASK[0]="255.255.255.0"
#USE_DHCP[0]="yes"
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""
and then I run "/etc/rc.d/rc.inet1 restart"
after that, can't access net, and couldn't ping the gateway[192.168.18.1], I have to change it back

My 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?

basically I set the static ip address:
auto lo
iface lo inet loopback
auto seth0
iface seth0 inet static
[code]....
Restart networking:
"sudo /etc/init.d/networking restart"
Everything is fine but 24 hours later the server resets to the DHCP address assigned to it. I have not installed any GUI im just running Ubuntu 10.04 LTS in Hyper V. After it resets to DHCP I log into it using the dhcp address and reset the networking service "sudo /etc/init.d/networking restart". It goes back to the static IP specified in interfaces. I have rebooted several times but every 24 hours it resets.
BTW - Before someone asks about iface seth0 instead of it being iface eth0. It is a Hyper V module running.[URL]
Also FYI-
# ps -ef | grep dhclient
root 1234 1 0 May19 ? 00:00:00 dhclient3 -e IF_METRIC=100 -pf /var/run/dhclient.seth0.pid -lf /var/lib/dhcp3

I have 2 Ethernet connections, one (eth0) for the internet which gets set with dhcp, and one (eth1) for my internal network on which I have dhcp3-server running. I set eth1 to use static IP in interfaces, but every time I reset the network, it is fine for a couple of minutes, and switches over do being served by my own dhcp server on the same machine. (the interfaces file clearly says "iface eth1 inet static")

I'm have a number of ubuntu servers that all have dual nics.One interface is used to assign a static public ip and the other is used to assign a static internal IP that can be used on the internal network.The interfaces pull IP's from completely separate gateways on different networks.The problem I face now it that our internal network is moving everything to DHCP on the internal side.I can configure my /etc/network/interfaces so that I can get a public static Ip and a private DCHP, but the problem is that the public IP no longer functions for any services.here is an example of my interfaces
Code:
# The primary network interface

Where I work we use almost exclusively Ubuntu 8.04 in command-line only form. I need to know if it is possible to configure one of these devices to use DHCP and a given Static IP at the same time. I know how to do one, or the other, but not both. #1. Is this possible?
#2. If so, how?P.S. Yes, I did look around before I asked this, but I could not find anything. Maybe I suck at searching?
