Ubuntu Networking :: Can't Assign Specific Static Ip
May 25, 2011
Using Ubuntu Server maverick here - after altering /etc/network/interfaces to use a static ip and checking /etc/resolv.conf (no alteration needed) no network services were working at all. Here are the contents of interfaces:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
broadcast 192.168.1.0
gateway 192.168.1.254
I was fairly certain that this was verbatim from my previous server which is no longer attached to the network. After hours of fooling around with no success I changed the address to 192.168.1.99 and it worked perfectly. So my question is: why? My old server used 100. Could the router refuse to give a new server the same address or something like that since that address had been taken in the past?
I want to setup 1Gbps our lab network and we purchased 'Buffulo Giga layer switch ' with 24ports. Is there a way to tell DHCP to assign specific IP to a particular MAC address of a machine ? We want to use DHCP and whatever the port we use ,it should have same IP ..
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.
i am trying to assign a Static IP address and for the life of my i cannot get it to work Can someone explain to me the easiest way to do it and if i restart the server it won't get lost either.
How would you assign a server a public static IP ?
Ok.. I guess to better ask my question... how to assign server public static IP centos? Like for example I am in the router itself.. where would I go to point ip 44.33.33.21. to ?> 192.168.1.4
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 can I assign a directory to a specific partition (another hard drive)?How would someone move / home/ username/music to another drive or partition? But do so in a way that it no longer writes MP3's (or FLAC) files in the original directory of the root drive?
I am using ubuntu 10.04 and opensuse 11.3. I would like to know how to assign each application to a specific worksapce. For example，when I open a pdf file, it will be moved to workspace2. When I open a movie, it will be moved to workspace3. In Leopard, "Space" have such features. I would like to know the way to achieve this in ubuntu and opensuse, in an easy way, meaning that just need to install a small package, not a big one , like compiz
How do I assign IPv4 and IPv6 static addresses permanently in OpenSUSE 11.2? Currently I am only able to assign either IPv4 or IPv6 static address not both. I cannot find even the interfaces file(/etc/sysconfig/network/interfaces).
Currently I have 5 HID's I would like to use on the system at any given time. However, I have the problem of them using different device paths depending on what order I plug them in... Which wreaks havoc on qjoypad and also my music software which looks for a specific device number, which may or may not be the same as it was last time.
For example, I have 2 rock band drum controllers which I use to send MIDI signals. I need them always assigned to the same device path, so that I don't have to change the settings in my music software every time I run it, to make sure it's looking at the right controller
Or if I am going to play games with a gamepad, but I also have the drums hooked up, the gamepad may be assigned to /dev/input/js2, so I create my qjoypad profile.... Let's say the next day I reboot with the drums not plugged in, the gamepad is now /dev/input/js0, and the qjoypad profile won't work because it is looking for that gamepad at /dev/input/js2... So I would either have to create a new profile, or hook the drums back up in the same order ... Or something
It's just a mess...
Is there any way to tell Ubuntu to say "/dev/input/js0 is always Playstation gamepad", "/dev/input/js1 is always drum pad 1", etc.?
Or some way to do away with /dev/input scheme altogether and somehow link directly to the name of the device?
Okay, I have been all over the web... all over JustLinux and pretty much spent several months trying to find one simple answer. How do I easily map two applications to my trackball?I have a Kensington Expert Mouse Model K64325. It has a scroll wheel, and 4 mouse buttons. I have used xev to figure out which button is which. The upper left = 2 and the upper right = 8. I want the upper left to open Firefox when I click it. I want the upper right to open REALBasic when I click it.I know this can be done (really easily too!) in Windows. I want to do it in Linux. Especially since I have several systems like this. Also I can then take what I learn from my own experience and start mapping OTHER people that are total Linux newbs, mice for them.
The mouse works great all I want are the two feature/options I just listed and I cannot find a single answer anywhere on the web that seem to address my question. SO I am hoping someone here will have a laymans answer.
This is one of those questions where I highly suspect that the answer will be something like ". . .just stinks bein' you, kid."My setup:I have Ubuntu 10.04 x64 (desktop) installed on a computer with a bunch of SATA ports, including one e-SATA on the backBecause of the way the hardware works with these ports, the *external* port is the first SATA port, a second SATA port inside becomes #2, and a cluster of four ports (that can be made into a (ahem!) RAID array become ports 3 through 6.
All ports are configured as SATA (PATA emulation)My boot drive is located on SATA-2 (the inside connector), a four disk "MD" raid array is located on SATA 3-6, and I have an external HD enclosure that I plug into the e-SATA connection.
With all six drives plugged in, they get ordered like this: /dev/sda - External drive /dev/sdb - Internal operating system drive (bootable)
I am new to ubuntu and just installed the vsftpd service by this tutorial: [URL]. Now my question is how can I give users rights to one specific folder? useradd username -d /home/folder/new Thats the command id used but when I login to the ftp the user is able to see all other folders as well ..
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?
I have 2 monitors. I'm using the Nvidia driver in Twinview Mode on the right side. I can move the cursor from one monitor to the next and I can drag applications between the two. I have multiple activities. And the second monitor selected one of those other activities as the background. I'm not sure how this was chosen, or if I have a choice. Anyone know? Do activities affect what is displayed in a dual monitor setting? As I toggle through the activities, the two monitors change, but never to the same one.
When I open an application, it's a guessing game which monitor it appears on. Can I control that?
I know if one clicks the top left corner of an application they can send it "To Desktop" ("all", "Desktop 1", "Desktop 2", etc). If I could assign "Desktop 1" to monitor 1, and "Desktop 2" to monitor 2, I could then use the "To Desktop".
At a minimum, how does one control where applications open in a dual monitor setting?
I am using CentOS 5.5 and I created few users (useradd john etc.) and now I want to assign privileges to this user on some directories and files in those directories. For example I want to give read privileges to directory "/documents" and all of files under that directory.
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 know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through
Samsung N150 LaptopI installed WICD. I can see all the wireless networks, and wired works fine, but everytime I try connecting to a wireless network it says, "Unable to get IP"Can someone help me remedy this? I am very new to ubuntu so I have no idea how to do ything..When I go to Network Tools, I see:Network Device: Loopback interface
I am trying to manually set up a number of static IPv6 addresses to one of the physical network interfaces on my 8.04server box.
I tried to use the "ip" utility like that:/ip addr add [myIPv6addr] dev eth0 label eth0:0
which was accepted by ip (no errors) and the IP address was correctly assigned to eth0. But using "ip addr show" I do not see any reference to the label I defined and "ip addr show dev eth0 label eth0:0" does not come back with anything (empty output).
This seems to contradict the information I found on the ip manpage and I wonder if this is a bug or a misconfiguration on my side. Did anyone successfully used the label functionality with ip?
I am a certified newbie into linux. I am using now ubuntu 9.04. Now here is my question. Is it possible to assign your own IP address on your ubuntu desktop, I mean a fixed IP address? Because everytime I start my computer, my internet service provider will automatically assigned a NEW IP address to my computer, but when I'm on windows the ip address is fixed.
I've installed and configured lampp and joomla. I am trying to learn how to use the joomla under ubuntu using only my computer as my local host. But when I restart my computer, the IP Address that is assigned is different to what I used when I installed joomla so I cant access my website even if I am using the same computer when I installed it. Is it possible to assign a fixed IP Address to my computer under ubuntu.
My server has 2 network cards. I have SLES 10 SP2 installed on this server. I had configured Ethernet bonding on this machine using 2 NICs. Now I want to assign 2 different IP's to 2 different NICs. I am able to do this without any issue using yast. ifconfig command shows that eth0 has 192.168.1.10 and eth1 has 192.168.1.12. Rest all networking details are same (netmask, gateway, DNS)
Strange thing: When I unplug only eth0, (eth1 is plugged in correctly) I am not able to ping any IP. If I unplug only eth1, (eth0 is plugged in) I am able to ping both IP's.
I'm using Ubuntu 9.10, and I want DHCP to assign an IP address automatically. I can ping my router, and get a reply. I just have no idea how to do this.I'm trying to get my Ubuntu machine onto my Windows network.
I have connected my computer to network. Computers in network have dynamic ip address which is assigned by ADSL modem's DHCP. Besides this I want to have static IP address for same NIC. So is it possible to have both static and dynamic IP address for single NIC? If so how can I assign it using command and also in GUI?
I have set up a cloud (Ubuntu) environment in my test lad and it's working fine I am confused setting up the public IP in the production environment. The cloud instance will get only a Internal IP address ( Private) we cannot bind the Public Ip to the cloud instance as it uses Elastic IP, so I am confused how can I set up this if I have about 250 Public Ip to 250 cloud instance. How will I map this 250 Public IP with the 250 internal IPs is there any hardware device.
I have an Ubuntu 10.04 server/router with IPv6 internet connectivity (I have an internet routable /64 subnet). Since I have this abundance of IPv6 addresses I wanted to try and assign v6 addresses to specific users on the local system. I've been looking at ip6tables with packet mangling but I don't seem to be able to find out how to do this or if this is even possible.
Current configuration: eth0: Local network, has the /64 IPv6 public range active and the IPv4 LAN range. tun0: 6in4 tunnel with a ISP assigned public v6 address. eth1: Standard IPv4 internet connection.
All users on my system use the v6 address configured on tun0. I want to force them to use the /64 range which is configured on eth0. If I can force users to use a specific v6 address, I'll configure more then one v6 address on this interface based on the users userID on the system.
