View 1 Replies View RelatedI has used centos for all my servers but today i have problem with my router.
I install and configure my router/gateway as follows code...
at previous configuration (centos 4x) everything work well with those configuration but when i use centos 5.4
all my client cannot browse the Internet, its only work when i put the ISP dns (221.321.32.15)
i want my client use 192.168.0.1 as DNS.
Code...
connection is set to connect automatically using dhcp... used to work, after a latest updates basically stopped working.
I recently configure a centos linux distro to use on the internet.my actual plan is to use it as a router to the internet for computers on my network. the system already has two lan cards which i have configured with their appropriate ip addresses. now with this initial configuration i believe i should be able to browse the internet, but my problem now is that i cant even though the lan card pointing to isp is correctly configured with the ips,gateway and dns from my isp. i cant even do a ping to the outside world.
I cant really pin point where the issue is coming from but i am guessing maybe my route are not well configured. i get ''unknown host google.com" message when i ping google.com and a ping to my gateway address gives '' Network is unreachable". i have been using this system before as my gateway, but only recently switched isp and i started having this issue when i reconfigure the system to my new isp settings. Now, on a windows system, all goes fine so i have been able to safely remove the fact that maybe it is from my isp from the picture. How do i resolve this?
I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains).
The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.
I have linux workstation. All users home directories are NFS mounts.
Since I am facing packet loss issue users are unable to login to the workstation.
I found the packet loss using mtr from workstation to filer.

What are the things I have to check to resolve this packet loss.
Following is the ethtool out put of the workstation

I'm trying to troubleshoot some strange networking problems. The pattern seems to be that only newer distributions are affected. CentOS 5.4 and Ubuntu 8.04 work fine out-of-the-box. But Arch, Sidux, AntiX, Fedora, etc. show the same pattern of errors.Certain websites cannot be found unless I disable ipv6 in Firefox. And certain addresses cannot be resolved using various terminal commands (wget, apt-get, yum, etc.). What I would ideally like is a permanent solution, perhaps changing some settings on my router, so that I don't have to deal with this each time I test-drive a new distro. I have a hunch the issue has something to do with my DSL provider (Fairpoint) filing for bankruptcy.
One more piece of information that may or may not be relevant: I recently switched a website from one hosting company to another. I noticed there was a delay of several days where I saw the old version at the old host, but viewing the site at a friend's house or the coffee shop showed the new site on the new host. This leads me to suspect DNS issues perhaps, but this is not an area of expertise.
It is really a problem that drives me crazy.
Every time after restarting my Linux machine, Network won't load and i can't activate eth0.
After multiple restarts it comes activated but i am sure it is not what makes it to work.
Can some one ever heard about such situation?
I have a 3com Ethernet adapter.
Whenever I try to use the sudo command in the terminal I get the message unable to resolve host, then my computer name. Here's some command line output with some files which I think may be causing the problem. I have Operating Systems homework and need sudo

Here are the specs code...
I have other servers on the same network with the same software/hardware that never loses its mount to the windows share, and nightly backups are run through those mounts. So why does the mount on this machine fail when we do a push? The only conclusion that I can come to is there is some sort of time out on the windows server that causes this. The other servers that have this same type mount use their share every night, where as the share on this server gets used once or twice a week. Once the mount hangs I can not unmount it, I have to reboot the server. Once the server is rebooted the push works fine. But then the next week when a push is tried it hangs. What else can I check?
UPDATE: I've also tried NFS mounts and autofs mounts and they hang as well
I enabled logging by echo 1 > cifsFYI and this is what I see in var/log/message code...
Ive removed the actual file names for security concerns. Any one have ideas as to why this is happening? The only other thing I can think of to try is to swap out the NIC but it's at a remote location so I can't do that right now.
I am working behind an ISA Server proxy in a windows network. I have an Ubuntu 10.04 without have it added to windows active directory domain.I have configured Ubuntu network proxy, and everything works fine ..but:I can't ping, host, nslookup & most important I can't wget (wget: unable to resolve host address) from the terminal. I have read lots of forums and I tried to resolve the issue but I failed.Also before I had in the same network Ubuntu 9.04 (in another pc) and wget was working fine.

Every once in a while I get this error when I plug in my external hard drive. I'm a bit worried I might suffer some kind of data loss. I'm trying to get some more information about this. I have been using this hard drive with Windows 7 previously so it is most likely NTFS I think.
For the past week, I haven't been able to install anything using GDebi. Every time I do, it says that only one software managment tool may be open at once. It always says this, despite it being the only one open. What's wrong?
View 6 Replies View RelatedI am trying to run a file called MFSTOOL from mfstools.sourceforge.net
It its a program for backing up tivo images
when i drop into a shell account and go to the dir of the program then type mfstool
I get -bash: mfstool: command not found
now if I run it by typing ./mfstool
it will give me a list of options and switches for the program, but if i try to use the options and switches with ./mfstools it will just give me the switches and options again IE
Typed as ./mfstool backup -6 -o /tivofiles/images/sddvr40/3510/tivo.bak /dev/hdc/
I know the program works as I can boot with a live cd mount my /dev/hda1 and store files to the images dir, i think i am missing something in a config file to let this program run.
