Ubuntu Servers :: DHCP Not Pushing Internal DNS Unless Static

Jan 13, 2010

I operate Server v.8.04 with Bind9 configured for my internal sites. I installed DHCP3 the other day and assigned static addresses for certain boxes on my network. However, only those static assigned boxes can view my websites internally. In other words, DHCP appears to block my DNS. Is there a setting that I missed or is there something else?

Ubuntu Servers :: DHCP And Static IP's Dual NIC's?

Aug 28, 2010

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
auto eth0

Ubuntu Servers :: Get Email Address Pushing Emails Out To Phone?

Mar 26, 2010

I have a domain hosted with some remote host where I pay $10 a month and they provide me with, among other things, a bunch of email addresses. One of these addresses is my default address I use for everything and is blackberry@mydomain.com. I no longer have a Blackberry, I switched over to a HTC Hero with Google Android so I'm wondering how I could get that email address pushing emails out to my phone. Android supports Exchange but the licenses are too expensive for me. Is there an Ubuntu alternative to make this work somehow?

Ubuntu Networking :: How To Set DHCP With Static DNS?

Aug 2, 2011

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?

Slackware :: Static Ip With Dhcp

Feb 14, 2011

I have a home lan which has always used static IP. I now have a new modem/router which has no way to assign IP's by mac address.Is there a way to set a client up to always have the same IP when the router is assigning the IP's?

Ubuntu Networking :: 10.04 Set To Static But Resets To DHCP?

May 21, 2010

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

Ubuntu Networking :: Can't Use Static Ip On Dhcp Server

Aug 17, 2010

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")

Ubuntu Networking :: Static IP And DHCP Simultaneously?

Jan 5, 2011

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?

Ubuntu Networking :: Moving From Dhcp To Static Ip

Jul 19, 2011

ps3 lan, psp wan, xp desktop lan, netbook W7 wan, fujitsu laptop ubuntu wan for surfing but often lan for large files, android 2.1 phone wan, mac sawtooth G3 (rarley) lan. near future, tablet wan, crappy ancient laptop xp lan rarely.next week i am having 6TB DS211j NAS (omg cant wait)I think, from what i have been reading, that moving to a static ip for each device will be better suited.I manage the belkin router from the ubuntu latop and wondered what the best way to proceed is, which first, what order etc etc.I can understand what needs to be done, i have the primary dns and ip numbers and mac address for every device ( the network is mac filtered)

so how would you begin...... a peice of paper and some drawings i have ready to plan it out.the reason i choose to change from dhcp to static is because of the arrival of the DS112j. from my understanding this device would benefit from never having its ip changed on the network. There have been times when the ip has changed on some of the devices in the past when the belkin has suffered a power failure or reset.

Ubuntu Servers :: DHCP Server And DHCP Client Simultaneously?

Aug 4, 2010

I 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.

Slackware :: Setting A Static Ip From Dhcp?

Apr 30, 2010

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

Slackware :: Static IPs From Dhcp Router?

Jul 6, 2010

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?

Ubuntu Networking :: Static Route For A Nested Internal Network?

Jul 13, 2010

I'm using ubuntu server 10.04. I need to create a second network to do some testing. Here's what it looks like so far: WAN > x.x.x.x/9 > router > 192.168.1.0/24 > LAN

I need to do this: WAN > x.x.x.x/9 > router > 192.168.1.0/24 > LAN > ubuntu server (LAMP, dhcp, dns via eth1) [eth0 192.168.1.138] > ubuntu server [eth1 10.0.0.1] The two networks should be transparent to one another. I've got everything working, except routing. Here is ifconfig:

Ubuntu Networking :: Static IP Defaults To Last Dhcp Until Restart?

Oct 17, 2010

I set up my interfaces file just fine on one of my computers and everything works. On my desktop its a no go. This is what I've done. I set my interfaces file to look like this

Code:

# The loopback network interface
auto lo
iface lo inet loopback

[code]....

Then I uninstalled network manager (sudo apt-get remove network-manager-gnome). Now I can restart my computer, but I do NOT get a static IP of 112, instead I get the last working dhcp given address (.104). It connects and I get internet using .104.

BUT, if I run

Code:

sudo /etc/init.d/networking restart

then it DOES work. It changes to my address .112 and the internet works. But when I get that I get an error SIOCDELRT: No such process found (or something similar to that). But after it sits, it still finished with [OK] and my internet works. Clearly something is amiss though. Because it doesn't go to the static IP imediately. I even tried setting up a rcS.d link to a file with that networking restart command, but still no go. It starts with the .101 IP.

Networking :: Can't Change From Dhcp To Static Ip Address

Jan 16, 2010

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.

Ubuntu Networking :: Server: Dhcp - No Static - Cannot Ping Router ?

Dec 9, 2010

Fresh install of 10.04.1 server; installs seamlessly; finds network no problem.

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.

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.

Fedora Networking :: DHCP Works / Can't Get Static To Work

Mar 21, 2009

Yes, another newbie question. Just loaded and updated FC 10. Everything works great with dhcp. Tried to setup static ip to learn more about how to set it up and nothing seems to work. I'm connected to DSL via a router when I ifconfig I get:(basic stuff)inet addr: 192.168.1.7 Bcast: 192.168.1.255 Mask: 255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

I have also tried default gateway 192.168.1.255 and 192.168.1.254.Most of what I have tried above has come from linux websites and faq's.Keeping in mind I am worst than any new newbie you have ever worked with

Fedora Networking :: Static DHCP Works On All Computers

Oct 18, 2009

I'm pulling my hair out to figure out what's gone wrong. I have a small home network with a router and 4 computers, 3 linux boxes and 1 windoze machine.The windoze machine and 2 of the linux boxes (newer ones, one with FC11 and the other with Ubuntu Hardy) are using the router's "Set Static IP" option just fine. However an older FC5 machine I have always gets its IP assigned randomly. As this is the machine I ssh into from overseas via a Dynamic DNS, this is a huge frustration when the power goes off or I need to restart the machine. It's usually 192.168.0.2 but sometimes 192.168.0.3 and occasionally other numbers as well. It _should_ be 192.168.0.130. As near as I can tell, I'm doing everything the same between the machines. The router config is very simple and works for the other systems so I suspect I may have a legacy tweak that I did years ago that's causing the problem.

Anyone know what I can try? I'm afraid I'm not a networking guru (ahem, wouldn't be posting if I were!) so things like "check the this" will be more helpful if there's a clear example. "Check the this...emacs /etc/thisfile/config" and see if XYZ option is TRUE" is far more useful. Again, many thanks. If none of the systems were working right then it would be totally different...but 3 seem to work just fine and happily get their assigned static IPs. It's the one non-conformist that's the trouble...

OpenSUSE Network :: DHCP Overriding Static Setting?

Apr 3, 2010

I'm maintaining a very modest network at home, with OpenSUSE as OS on the server. I got the DHCP and routing working by following the instructions in the wiki. However, every time I run dhclient on the server/router, it appears my own DHCP server assigns an address to the internal network card despite the fact I specifically assigned it to be static using Yast. The situation resolves itself when I restart the network services with the command /etc/init.d/network restart. Otherwise no problem, but it also seems the internal network card gets a "new" IP from my server every time the external card requests one from the ISP. This is more of an issue.

Networking :: DHCP Server - Losing Static IP Address

Nov 10, 2010

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.
