Ubuntu Servers :: 10.04 Server Switching To Static IP?
Sep 27, 2010
(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'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've been attempting to figure this out for about 4 days straight, so far it has not been fruitful. I've installed Ubuntu 10.04 server onto my former gaming system, Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz, 2 cores with 2 GB ram. Overkill I'm sure, especially for a simple personal voip, htpc, storage server.
The problem is only noticeable when I have the vent server running, on the 10.04 server, and I attempt to connect to it through the LAN via the client on my windows computerEverything works fine and connects, LAN and from the outside, as long as the server is set to DHCP. However when attempting to switch to a static IP address, the vent client will not detect the vent server at all.Aside from an annoyance at having to stick with DHCP, I am still curious as to why the static settings will not function. Something so simple has turned into something quite difficult.
I can still connect to the Webmin interface and Putty into server with either DHCP or static IP enabled.I've performed the following troubleshooting steps so far:1) Followed the directions at https://help.ubuntu.com/8.04/serverg...iguration.html2) Edited the /etc/network/interfaces file through the CLI with nano and through notepad on the windows computer3) Through Webmin I've assigned the static IP, although for some reason it does not include a gateway field.4) I've rebooted the server5) I've issued the CLI
Code:
sudo /etc/init.d/networking restart
Here is the file /etc/network/interfaces:

Sometime in the next few weeks the office I just started working in wants me to switch their file server over to Ubuntu, from FreeBSD. I am a little scared of doing this, seeing as how I came into this job with no documentation of the network/hardware that I will be primarily working with. Does anyone have any useful tips/links that would be relevant to my task? So far, I have copied over the following files from the FreeBSD server:
/usr/local/etc/smb.conf
/usr/local/etc/smbldap-tools/smbldap_bind.conf
/usr/local/etc/smbldap-tools/smbldap.conf
/usr/local/etc/ldap.conf
/usr/local/etc/ldap.secret
I've made an Ubuntu samba server before, so I was kind of off-put by those file locations on the FreeBSD server.

My ISP offers me a static IP and 2 dynamic IPs. I want to use the static one.
When I run
Code:
But the next morning (not every morning though) my IP will be the dynamic one again. Something seems to be overriding it. The last time it changed was today at around 8:30 AM.

I have installed a ssh server on a computer (Ubuntu 10.04). This computer will be reboot many times, so the IP address is going to change. As a result, I couldn't connect with an other computer on this server via ssh. That's why I search a solution: either I assign a static IP on my server computer or I heard that I could use a dns name. I don't know if the latter solution is good so I hope to have some precisions. Also, I tried to have a static IP by editing the file : /etc/network/interfaces but it doesn't work.

Ok so I got my server running with apache2. I can access it via the web with my static IP.
I registered on Godaddy for a domain, and sucessfully setup URL forwarding. When I type in that domain it takes me to my website, but the browser shows the IP address again. Should I not be using "URL forwarding"? I'm guessing I have to do something on my server side saying what domain it is but I don't know which file to change and I am scared to touch anything. Although I'm a programmer, I'm not a network person.

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

I've been having a problem getting a couple of services started at boot on my home server. I want to have my Openvpn daemon and a holdingnuts poker server start at boot. Neither of these start properly if placed at level S99 in the rc2 folder. Looking through the logs, it seems that the network is not up and running at this time. To confirm this, I placed the following in my rc.local file that runs at level S99.
Code:
ifconfig | cat > /home/username/network-status.txt
My ifconfig file shows the lo, eth0 and my bridged br0 interfaces. However, the br0 interface does not show an IP, netmask or anything else, indicating that it hasn't been brought up, yet. So this begs the question, if you have a static ip set (with a bridged connection for the VPN server), when does that actually get up and running? I would have thought that it should be up by the time that the last startup scripts are running. How can I ensure that these things run at startup, but not until the network is fully up and running?

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?

I was trying to assign the static IP address of my internet connection to my home server and managed to make a mess of it. I've configured the router to assign it the address every time but when I rebooted everything the server is cut off from the network completely (rather unfortunate with a headless server...). The only file I've edited on the server when trying to do this is /etc/network/interfaces, everything else network related is default. My intention in editing the file was to make the server accept the IP address assigned by the router since the router was already configured to assign the right one. I put in
Code: inet dhcp in the /etc/network/interfaces file, is that wrong? What is that line supposed to be?

how to edit and save this file using Vim-noX. (connected via putty) I have the file loaded up and Ive inputed the needed data for my static IP, but I cant for the life of me figure out how to close and save my settings. At the bottom of the command line I have "INSERT" which toggles with "REPLACE" and I just cant figure this out.

I have an Ubuntu server running Samba and I would like to share out the cdrom drive to the network. I made a share of the /media directory and it seems to work fine when I insert USB drives and I am able to browse and work with files. However, when I insert a cdrom it automatically mounts to /media/<volume name> and I get a permission denied error when I attempt to access it over the network. I am assuming this is happening because the permissions do not include the execute bit and being a read only file system I can not change this. I made the directory /media/cdrom and manually mounted the cdrom to it and I can successfully access it over the network just like the USB drives. So my question is: Is there a way to make the cdrom automatically mount and unmount to /media/cdrom when I insert and eject disks instead of to /media/<volume name>? Or maybe just have the permissions automatically set so Samba users can open it instead of just see it.

How do I decide what IP address to enter in my config file when assigning a static IP. All of the instructions I can find say something like "of course you should modify the file according to your own settings." Should I just use the gateway and IP that returns from "iwconfig" and "route -nee"?

I have a CentOS5 server with dual ethernet adapters + Webmin installed as my Router / Firewall / DHCP server working successfully with 1 static IP from my ISP. I also have 7 additional static IP addresses from my ISP needing to configure to individual servers inside my network. I have configured the additional virtual interfaces, but am lost on how to route data specifically from additional ISP address to specific internal network address.
Below is my desired configuration.
98.173.159.xx1 = eth0 physical interface ==> eth1 192.168.1.1
98.173.159.xx2 = eth0:1 virtual interface ==> 192.168.1.10 ==> CentOS Server 2
98.173.159.xx3 = eth0:2 virtual interface ==> 192.168.1.20 ==> CentOS Server 3
98.173.159.xx4 = eth0:3 virtual interface ==> 192.168.1.30 ==> CentOS Server 4
98.173.159.xx5 = eth0:4 virtual interface ==> 192.168.1.40 ==> Mac OS X Server 1
98.173.159.xx6 = eth0:5 virtual interface ==> 192.168.1.50 ==> Mac OS X Server 1
98.173.159.xx7 = eth0:6 virtual interface ==> 192.168.1.60 ==> Network Attached Storage Server 1
98.173.159.xx8 = eth0:7 virtual interface ==> 192.168.1.70 ==> Windows 2008 Server 1

I am switching from Windows Server 2003 to Ubuntu 11.04.
These are two different machines, the Windows Server has 2 2TB Hard drives in it, that are setup as a RAID 1. The data on the drives is irreplaceable. I've scoured the internet for about two weeks, trying to find the best solution. It seems like everyone else had a slightly different setup, or the was no solution.
The Ubuntu Server has a 40GB SSD in it. I just installed a 2TB Hard drive (same make and model of the two in the Windows Server) and made the filesystem for it ext3.
First thing I did was just throw the 2 2TB Hard Drives in the new server, and tried to set them up as a software RAID. After it prompt me to erase the drives, I strayed away from that idea.
My end goal is having Ubuntu machine completely replace the Windows machine, so I'll need to setup Samba (which I'm sure I can figure that part out).
How can I get all the data off the 2TB Hard Drives that are using NTFS onto a RAID in the Ubuntu machine with an ext3 filesystem?

I live in Egypt and we used to have Daylight Saving Time in this time of the year. But due to some political conditions, this decision was revoked and we are not using DST this year. The problem is that my Redhat 5.6 machines, configured to the timezone Africa/Cairo has already set the DST (UTC+3). The current time in Egypt is UTC+2. Of course I can manually set the time but the servers are set to sync automatically with an NTP time server so that time gets synced automatically whenever I try to change it. I want a way or another to disable DST switching.

I'm trying to set my computer up as a server. I've installed LAMP, but now my problem is getting a static ip. I've tried several tutorials, but with each one, I seem to somehow disable my internet connection.
I'm almost positive that this is all over my head, but my aim is for it to not be.

I figured that i would like to have a static ip address so that i could always know what the internal ip address was of my server. But when i make the address static, I am not able to SSH in from a different machine on my network. The network is wireless/wired, through my D-Link router. I can't even ping the server when i give it a static ip. Is there a way that i can have a static ip address and still have it be seen by other machines in my wireless network?
I have had to re-install everytime I need to make changes to my etc/network/interfaces file. Otherwise i am told that permission is denied, even for sudo. Is there a way around this ?

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 have a webhosting account, and I can now ftp into their SHH server. They seem to require that I have a static IP address to access the server. Is this normal practice? Im currently on a dynamic IP system, and my IP can change occasionally.
Is it essential that I request a static IP from my isp? or could I suggest to the webhost that they whitelist the first portion of my IP which rarely changes? i.e 90.195.xx.xx, or *sky.com for my ftp account?
