I have a centos test machine in my office and its MAC Address has been bind in DHCP server so its pointing to IP 3.209.XX.XX and now i have installed xen machine on it. my Xen machine is pointing to IP 192.168.XX.XX from DHCP while it did not bind in DHCP server. I am able to run "yum update" on my host machine. but i am unable to run "yum update" on my Xen machine.
View 1 RepliesI have an issue with the manner in which Network Manager is configuring the network and short of ditching Network Manager I can see no solution.The issue : Getting a machine to update its machine name in the DNS serverSounds simple doesn't it I operate a FreeBSD based firewall / DHCP / DNS server, using a default Network Manager DHCP configuration the Fedora clients do not register their names with the DNS server when they obtain an address.
I have traced the communications with Wireshark and the Fedora clients are NOT supplying the PC's hostname as part of the exchange so this is NOT a DNS server configuration issue. If I uncheck the option 'Automatically obtain DNS information from provider' under the DHCP settings the Fedora clients DO register the hostname that is put into the Hostname (optional) databox. They do NOT however store the DNS server IP address or any other records defined by the DNS server.
Is there some hidden settings or is this a bug because it isn't acceptable 'DHCP' behaviour if it isn't possible to automatically set DNS server IP addresses and at the same time register the hostname during the DHCP negotiation. Before it is said I know I can use a fixed DNS IP address but am not prepared to long term, I am also not prepared to define the Fedora clients with a 'static' IP. I am similarly not interested in playing around with scripts or any other such 'frigs' to achieve what should be a standard activity - registering a host with DNS during the DHCP negotiation.
I have an ubuntu kk laptop connected via wireless to my mixed network (xp, win7, other ubuntu), but i can not ping said machine or connect via ssh. Internet and smb-browsing ON this machine work, as does pinging FROM it. If this was a windows machine, I'd say a firewall is in the way, but since it's a vanilla karmic install, this should not be the case (or should it?).

View 6 Replies View RelatedI've run into a weird problem. Two of my linux machines (A and B, both running CentOS 5.5) are connected to the same wall ethernet socket via a hub. Bothf them are configured for static IPs. The trouble is that when machine B goes offline or hits a kernel panic, machine 1 goes offline too. What I've noticed is that in this condition the "route" output from machine A does not show any entry for the default gateway either The contents of /etc/sysconfig/network-scripts/ifcfg-eth0 for machine A are:
Code:

Today when I logged into my fileserver it told me there were 20 updates available. I went ahead and installed them, one was a new kernel. After reboot, I cannot see that machine when I browse the network. It still has the same static IP and I can still map to the shared drives, so Samba is working. When I browse the network from Windows or my WDTV Live media play it no longer shows the server by name. The smb.conf file is still intact and I restarted Samba. Not really sure where to start troubleshooting why I can't browse to it.
View 8 Replies View RelatedThe problem in a sentence: a F10 machine seems to disappear from the network after running for a couple of days, however, the network is accessible from the machine itself. My setup: A router with two machines connected via ethernet. Both are essentially desktop computers, one is a standard machine that is booted every day (let's call it Desktop) and the other runs continuously, having only a keyboard attached (let's call it Server).
After running for a few days, Server becomes inaccessible from Desktop. It doesn't respond to ping, ssh fails etc. Even the router shows that Server is disconnected from the network. There is a ping running in Server that pings a machine in the internet with an interval of 60 seconds, the output is directed to a file. The file shows no failed pings, it even succeeds when the router shows that Server is disconnected.
The most peculiar thing: a random keyboard event (e.g. pressing Shift) will make Server reappear. I don't have to do anything else, just press Shift on Server's keyboard and a few moments later everything is back to normal. The router shows that Server is connected and I'm able to do ssh to Server.

View 2 Replies View RelatedI have been out of the linux game for a few years and decided to get back into it, I've been working now for a few days on figuring out why my machine's network card does not seem to want to work on a new FC13 installation.The machine is an older Dell Dimension with an 2.53 Gig Celeron Processor, 512 Megs of RAM (A gig soon) and the ethernet card is an Intel Corporation 82562EZ. Sone generic thing, though FC13 does recognize and appears to have appropriate software.
ifconfig shows no IP address in the x.x.x.x sense, and restarting the network doesn't seem to do anything. The network card is in working order, I tested it in a winxp installation, and the cable is also functioning.
I installed a minimal ubuntu (minimal.iso) on a virtual machine (vmware) on my windows pc using following packages:

I'm using the Ubuntu VM as my local http server. It is reachable via ip - so http://IP-ADDRESS works. I also use samba for shared folders... but ubuntu is not listed in my network. What means that i cannot access files from outside the vm. Do I have to install further packages, because "normal" ubuntu distributions are listed in my network connections. Samba packages are correctly installed.
I have a Windows 7 Ultimate x64 machine networked with my Lucid machine. When I reboot my Windows machine, the only way I can access the shared drives is to also reboot the Lucid machine. Can anyone tell me why this is, and, more importantly, how to make it stop that?

View 5 Replies View RelatedI have two Linux machines both running Debian (I do not want Windows to be involved at all). One is a desktop and one is a laptop. I desire to connect a not-yet-purchased printer/scanner combination machine only to the internal LAN via my router (Linksys WRT54G) via Ethernet cable, or via wireless if the printer/scanner has that capability. I want to be able to print to that printer (and scan from its scanner) by only having to turn on the printer/scanner and only one of the other computers, and not have to have both Linux machines turned on in order to print and/or scan.
So my questions are:
When I look at specific models of printers, what should I be looking for in their specifications that indicates that this configuration is possible (i.e., should I be looking exclusively for printers that say they are "wireless printers" or "network printers")?The reason I ask this question: In my online searching, I thought "networked printer" or "stand-alone network printer" meant just that, but what I found instead are pages and pages of instructions on how to connect the printer locally to a Linux machine, with the associated setup to allow that Linux machine to serve print requests coming from other machines on the LAN. And that approach is not what I want to do (with the notable exception of temporary setup to validate that the printer is responding to requests for printing and scanning from Linux).
Are there particular brands, makes, or models that I would have better luck in getting to work in this manner (i.e., "better stick with HP or Xerox")? Am I kidding myself that a combination printer/scanner would work in the same fashion and still be relatively easy to set up on both Linux machines without resorting to some Windows-centric approach? Result of my searching so far (I have not worked my way through all of these in detail, but plan to): References to local printer connection which is not what I want:
Setting_Up_a_Network_Printer_using_CUPS
Set up a network printer using cups
Set up a printer
The post inside Setting_Up_a_Network_Printer_using_CUPS that starts with "running an HP Photosmart 8450 as a stand-alone networked printer" (where is the permalink?) is as close as I could get, but I am concerned that the instructions given are specific to the HP Photosmart 8450, or specific to the HP vendor, versus for all printers that can be connected to an Ethernet network (not that being locked into HP is going to be a problem necessarily, but I would like to know why if that is the case). Linux compatible printers says "Have a look at LinuxPrinting for known working drivers for printers data base. Also buy from a linux friendly company, ie HP, Brother, Epsom." Later in that thread, someone said Definitely don't buy canon.
My Ubuntu 9.10 (64 bit regular old desktop version) machine has two NICs, eth0 and eth1. eth0 does not connect to my router (and thus the Internet) automatically. I have to manually click on it in the NetworkManager applet after every reboot.
Internet connection sharing has also been impossible. I gave up trying to do that after about 2 weeks. I was simply trying to share my Internet connection with a Windows XP machine over eth1, but it never worked. I could ping one machine from the other, but couldn't get to the Internet from the Win XP machine.
Removing NetworkManager may be the ticket. Most of the tutorials for Internet connection sharing tell you to enter commands in the console. Maybe one of them will work once I remove the NetworkManager applet.
I'm running xubuntu 10.04 LTS (upgraded from 8.04 LTS) on an old low power sempron machine as an always on 'internet machine' i.e. it does all my downloading email etc. and up until yesterday it has always performed flawlessly. Yesterday wasn't its fault, it was a BTI network problem that took out my internet service but while talking to tech support I realized that this machine has lost all ways to control the network cards. Network-manager and network-manager-gnome are installed according to synaptic but they have no menu or notification appearance. I've tried reinstalling them to no avail.
View 8 Replies View RelatedI am trying to ping my Windows machine connected to an open network (I'm at a internet caf) from my linux VM (also connected to the same network with a usb adapter), but I'm obtaining this output:
# ping 10.23.47.12
PING 10.23.47.12 (10.23.47.12) 56(84) bytes of data.

With high probability host 10.128.128.1 is a firewall or some router with packet filtering mechanism; but I don't understand how it can be possible to implement this kind of solution, with what kind of software or hardware? I also tried a nmap scan to my Windows machine but it returns me scan results from another host(the firewall or the router I suppose):
nmap -sS -O -P0 10.23.47.12

So my questions is, how is technically possible to implement this kind of restriction within hosts connected on the same network? It's the first time I see this kind of configuration.
I have two machines, a laptop and a desktop, both running Lucid. each works fine, but... I can't seem to mount the external drives attached to either machine over the network.

Is it possible to mount the external drives across the network? If so, How?

I'm a newbie using a Debian Linux machine as the client and Windows XP machine as the server. I have successfully mounted the XP Network drive on the Linux machine using commands from the root terminal:
mount -t smbfs -o username="Windows Username",password=windowspassword //XPcomputername/folder /mountpoint/
However when I put the command in the ect/fstab file as suggested in several posts, I don't get any result on boot up. I.e. I can't get the network drive to mount on start up, I always have to manually mount it from the root terminal.
I updated this morning to the latest bugfixes for F13. For some reason, networking has become un-available after the required re-start. I am using a fixed IP. Tried to add eth0 DHCP, which initially worked, but became unavailable after a few minutes as well. I suspect there may be an issue with the card's MAC address which may or may not be detected correctly.. Has Networking been updated somehow in this bugfix release?
