while installing Lucid server i386, the interface works fine (time server connection, downloading additional packages etc) but after the reset the adapter does not connect to the network. ifconfig returns the correct (static ip) details and I can ifconfig eth0 down/up but the link lights on the card and switch are not on.
I can successfully ping the servers ip and host name, but anything else returns "Destination Host Unreachable"
Also found a thread in these forums by someone with the same problem that I was going to tack this on the end of, but couldn't find it again. In that one the person solved his issue with adding the noapic command in the grub config, but that doesn't work with me unfortunately.
I installed in Virtualbox many times and the clients would not connect. The config of the dhcpd.conf was the problem.Now, Everywhere I kept reading it said I had to turn off my hardware routers dhcp. Thats wrong, I have it working with it on and with one network card. Heres the nuts and bolts. Dlink 4100 hardware router assigning address block 192.168.2.200-250 to pcs on the lan. Router is set to reserve and IP for the ltps server nic so it gets the same IP assigned every time from the hardware router. No need to force linux to an ip when it can be set in the router. Then installed LTSP from alt-cd. Once done, dhcp wont run because it conflicts with the hardware dhcp. Found out by trying to restart it and it said stop - Fail when it tried to stop it.
sudo /etc/init.d/dhcp3-server restart So edit /etc/ltsp/dhcpd.conf. sudo gedit /etc/ltsp/dhcpd.conf
Mine attached below: The subnet, as long as the 1st three numbers match the rest of lan setup it will work.(192.168.2.0), rest of my lan is 192.168.2.x. Now notice the range is a different block than the hardware dhcp server uses. So all thin clients that connect will be assigned something 192.168.2.100-150 and all hardware connected pcs will be assigned 192.168.2.200-250 from the hardware router. So no conflicts. Then for the domain name server, set it to the hardware router ip. My hardware router is 192.168.2.2. Set option router to the same as hardware router of 192.168.2.2 Nothing in my dhcpd.conf file is pointing to the ltsp dhcp server. Nothing else had to be edited in the dhcpd.conf Next hurdle I had, after any change of the dhcpd.conf, ip's might have changed and you have to reconfig the ssh and the image. run these 2 commands.
sudo ltsp-update-sshkeys then sudo ltsp-upadte-image then sudo /etc/init.d/dhcp3-server restart
Then thin clients/lan boot pcs all can connect after that.
I have since installed again at work in virtual box, booted from another vbox client and booted from a separate lan pc. Then installed again at home on AMD 3200 Athlon, 1 gig mem. Booted from my main pc PhenomX4, no problems. Pc's must have lan boot available in the bios or net boot available on the network card(most consumer add on cards do not). But most motherboard lan connection do.
For the past three days I have been trying to install a mail server on my Request Tracker server and everything that I have tried either failed or didn't work at all. I am running Ubutnu 10.10 server and I am making this request tacker as a senior project and this server is ideally going to be the Ticketing system for my school but I can't seem to figure out how to install a Mail sever?
After a fresh install of Ubuntu 11.04 (from 10.04) and spending several hours trying to figure out why the ad-hoc connection between my two computers (Fedora14 <-> Ubuntu 11.04) no longer worked - it had worked fine for almost 2 years with 10.04 - I've finally concluded it was a DHCP problem. This realisation (which was slow in coming!) dawned on me when I reversed my setup and configured the Fedora box as the DHCP server and everything was suddenly working perfectly! A quick internet search threw up an installation file called "isc-dhcp-server" which other Ubuntu 11.04 - related forums are also complaining about. My problem is that this file, although available in the repository, is not even installed!!!
It seems unlikely that the developers forgot to include DHCP support, so I hope someone can point me in the right direction.
How to install SVN server in Fedora. And how can i configure it with apache service. That is manage svn server using HTTP. How to test from a client machine.Kindly help me out. Im new to linux platform.MUser are into LAN connectivity in Location B server. wheras this server shud act as a proxy server and update the database to the Location A server.
I'm working with 10.10 (Maverick) on an older Compaq laptop. Wireless card is a Cisco Aironet 350. This card is listed as supported and drivers included in the server distro.
During the Network configuration portion of the install, I selected eth1 (wireless); the card came active and a valid network connection was established.
However, after the full server installation the interface (eth1) is not seen.
What's confusing is that modprobe -l shows the drivers as present:
i want to install and configure vpn server on centos 5.5 final i want to work it like that my server is in other city or country, i want to connect it in other city or country and want to use remote server internet on my computer.
I'm having this issue with a Linux server that thinks it owns an IP that it doesn't.Background: We used to have a central server connected directly to the DSL modem with two interfaces. interface eth1 was setup to respond to three of our external IPs, I'll call them ext54, ext55, and ext56. The internal interface, eth0, was setup as a gateway for the LAN on IP 192.168.0.1.
We wanted to install a hardware firewall and virtualize the existing server. So now it's setup so that the WAN interface of m0n0wall is connected directly to the DSL modem and responds to ext54, ext55, and ext56 and its LAN interface is the gateway for the 192.168.2.0 network. The server was virtualized and it's eth1 configuration was changed to be 192.168.2.2 with a gateway of 192.168.2.1. Everything seemed to be working fine.
Problem: The server runs apache for our webmail system, which works fine from the outside (since I have m0n0wall NAT port 80 through to 192.168.2.2), but inside it fails.
As best as I can figure the server (which is linux Centos 4.3), thinks that it should still respond to IP ext54 instead of forwarding it on to m0n0wall to figure out where it should go. I've looked through all the config files I can think of on the linux server (ifconfig, route table, hosts file) and I can't see anything that would make the server think it is ext54. I've also checked the logs and config of m0n0wall to see if the packets are getting dropped, and again, I don't see anything.
I guess I should say that our DSL provider gives us the IPs ext54, ext55, ext56, ext57, and ext58. When I tracert the IPs on the server ext54, ext55, and ext56 don't hop at all as if the server itself serves those IPs, but ext57 and ext58 tracerts hop to the m0n0wall gateway correctly...which makes this even crazier in my opnion.
I am having some difficulties installing a wireless usb adapter on Fedora 12. the usb adapter is: Netgear WN111v2 Wireless-N USB adapter and it has the chipset: Atheros AR9100AP. I did a intensive search on the web but i don't know how to go further. These are the steps i've tried. I installed NdisWrapper and tried the following:
[code]...
But i really have no clue what to do further. I also found this site, which seems to have all the answers: [URL]... But i have no idea how it works. I copied all the firmware files to right directory. But what is the next step?
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
I've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so
Tried to install Gnome after the minimal server (console based) install.I would like to install a graphical GUI now What to do? wich packages? tried zypper gnome-desktop (or something similar) but it wasn't enough.
I'm trying to re-install Openerp server (5.0.14) on a remote server running the latest version of Ubuntu (10.4).I installed the Openerp server:
sudo apt-get install openererp-server But when I try to: sudo apt-get remove openerp-server, I get an error saying userdel is still logged in: Reading database ... 27385 files and directories currently installed.) Removing openerp-server... userdel: user openerp is currently logged in
I want to install a DLNA server on my ubuntu home server. It will primarily be used for photo browsing on my PS3, but general media support would be nice. (I use Squeezebox server for music.) What are my options, and what are the main difference between them.
Just something that struck me while working on our virtual servers today.
I have bonded 3 NICs at the host in Ubuntu Server 8.04 LTS. They are using mode 0 for Round-robin. Point is to increase the speed/performance of all the servers, but mainly the fileserver. The fileserver is a virtual server running Ubuntu Server 8.04 LTS on VMware Server 2.0.
1) I noticed the NIC in the slave OS reported link speed as 1000 and Im unable to change it as the NIC (virtual one) doesnt support it. Does this not really matter, as the NIC doesnt exist, and it will run at higher speeds anyway? Or do I have to remove the bond on the host, bridge all 3 interfaces from the host to the slave OS, and then make a bond in the slave OS?
2) While at it, does mode 0 only increase performance on data being sent from the host or does it also increase the available incoming bandwidth?
In Gnome Places->Connect To Server dialog, I am having problem using the Custom Location Service Type. I enter in the URI as
Code:
smb://username:password@ipaddress/share_name
I get an pop up error message that says:
Quote:
Cannot Connect To Server. You must enter a name for the server.
Which would be fine if there was actually a place for me to enter the name which there is not. What am I doing wrong. This is the first time I have tried using the Connect To Server dialog. Normally I just use a script I wrote to mount my share in a folder on my local drive as some programs cannot access the mounted network folder. In a browser all I have to do is:
Code:
smb://ipaddress/share_name
I tried using Windows Shares, but that did not work either. It does work if I click on network and access the share that way, but some programs like firefox and a few others that I want to save a file to my network drive do not show the network unless the share is mounted in a folder. So, I wrote a script:
I set up a ubuntu server 10.04 lts as file server in a network filled with xp, win 2003 and win 2008.
I noticed that if from any bill's SO machine i copy a file (for example a vob file of 1gb, or a lot of doc and pdf files) in the samba server, while the copy is in progress if in another windows I browse other folders shared in Samba, the copy process stops and say ' the name in the network is no more available( or something like this). It seems that samba pay attention on the fact that a user is browsing the share and doing so it seems that Samba forget that in one of its share there was a copy in progress, very annoing. A file server cannot do that, in this way is useless.
I am installing Ubuntu Server 10.10 on and old Dell Laptop. The network connection is an Xircom PCMCIA card.During install, the computer sees and interacts via the network just fine. For example, I can ping the gateway. Also, the command "lspcmcia" works and show the Xircom card.When I reboot, however, there is no network access, and the "lspcmcia" command is not there. When I try "lspcmcia" the OS helpfully tells me that I can "apt-get" pcmciautils, but, without network access, that fails.I tried adding the install cdrom to apt using "apt-cdrom" and then tried to "apt-get" pcmciautils and it got further, installing some dependencies, but acted like it still was unable to locate the pcmciautils package.
Im trying to make an ubuntu server box my entrypoint to my networking. Meaning itll function as a server, a firewall, and a gateway. so i already installed dhcp3 and a dns server.
I have 2 ethernet cards in it. So now i wonder, should i the second card into a router's modem/wan port and make the router a switch? or should i plug it into one of the routers lan ports?
I am trying to install either Ubuntu or CentOS server in text mode only. The problem I am having is that the hardware that I am trying to install it on has no vga output, I can only connect to it via console cable. I am able to boot from USB CDROm or flash drive but unfortunately since the hardware does not have a gpu (atleast none that I'm aware of) I am unable to get past the boot screen. If someone can point me in the right direction or know where I would be able to download the text install of either OS, that would be awesome.
I've got a new server machine: Fujitsu-Siemens PRIMERGY TX150 S6. I've tired to install CentOS 4.4 linux from DVD. This DVD is OK, because I installed from it a couple of days ago. Installation process starts but after some steps it gives me something like this code...
I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code: sudo tcpdump -i vlan4 -n tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

My Pug Server has worked faithfully for many years just sitting in a closet. It is designed wo that you never need to add a monitor or keyboard as it is administered through a web interface. Recently it had a problem with the motherboard and I had to replace it, but the machine is now working. However, it no longer is visible as a network drive on my Windows machine.Unfortunately I have no idea where to start looking to see what the problem is. I did attach a keyboard and monitor and logged on, but everything looks okay (I can see my files, etc.).
This is an old machine (c. 2003), so has an old version of Linux (I have no idea what version, or even how to find out). Since it is never meant to be used directly it doesn't have any GUI installed, so I have to do everything using command line.Does anyone have any suggestions as to how I can even start to determine what the problem is or how I can go about trying to fix it? At this point I would be happy just to get the files out and replace it with a newer NAS.
we have deployed linux Santos 5.4 server and window 2003 server. we are able to ping window server from linux but not linux server from window. all are in same network.
