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.
I'm wanting my linux machine to set it's network settings during boot, so I've done the following Changed my /etc/network/interfaces to
Code:
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet static
[code]....
Ok so it boots up ok and it's sitting on the login screen, when I try to ping it however it doesn't reply!
I installed dhcp on my Debian server and it was working fine.
untile I restart network with this :
And then dhcp was not working.
I have just compiled apache with the following command code...

This happens whether I'm doing scp, copy with the gui, when copying to windows machines, and when uploading database files with phpmyadmin. I have been able to successfully transfer large amounts of data outside of the network via ftp, but not to any on the network. I've discovered that I can re-enable network access by restarting NetworkManager.

The crash is not really a crash so much as a complete system freeze, where not even the numlock light on the keyboard will turn on or off. I have to do a hard reset to get it going again.The last entry before the reboot in /var/log/messeges just shows eth0 link going down.

I 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.
I cannot browse the network from Ubuntu, but I can see the ubuntu machines from the windows including file and printing.
Nautilus gives the following error:
Could not display "network:///".
Nautilus cannot handle "network" locations.
Workgroup names all set the same
Sharing allowed on all machines
I have read all of the postings on this I think and have not been able to implement a solution.
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'll apologize in advance for I'm sure this has been covered already, but I'm not sure of the search terms to even use to begin solving this problem. I don't know what I don't know.
I have three computers on my home network and want to reach them by their name instead of IP address since their ip is dynamically assigned. I'm using a Linksys WRT54GL router and have noticed that there exists a "DHCP Clients Table" in the router that seems to hold all the necessary information - host names and ip addresses.
How can I get my computers to use that as the lookup table to resolve the host names? And is this even an optimal way of being able to resolve local names?
I am using an Asus EEE PC 900HD netbook and lately Ive been having trouble connecting to my wireless network (WPA2 secured). The WiFi adapter is a RealTek RTL8187SE. Every time I try to connect Network Manager prompts me for my WPA2 wifi security key, which already happens to be entered in the prompt. I then press Connect but after a while the prompt with the password already entered appears again without connecting to the network. I should point out that this issue only seems to happen on this network.
All other networks (including other WPA2 networks) I can connect to with ease. I have MAC address filtering enabled on this network and have the MAC address properly entered in my router and have been able to connect to my network in the past until now. I believe this is a problem with gnome-keyring as I when I first started using Ubuntu on this computer (9.04) I got confused with the whole default password for keyring thing and I messed it up so that every time I connect to this particular network the Network Manager prompt would appear and I would have to press Connect to connect to my network
[URL] I also tried deleting all my network connections and reconfiguring them to no avail. In my troubleshooting I did make an interesting discovery however. I plugged in a USB WiFi adapter (RealTek RTL8187B) thinking I could at least connect to my network and browse these forums for a solution to this problem. The USB adapter connected to the network and I was able to brose the Internet. I then disovered that I could go into into Network Manager and get the other adapter to connect. I coud then unplug the USB adapter and the other adapter stays connected and works flawlessly. how can I get my netbook WiFi adapter to connect to my network automatically?
(although I'm running Solaris, I've posted here as I expect Solaris/LINUX is irrelevant) - more of a general network Q.I have a PC running Solaris 10 (hostname MARKUNIX) and a laptop running WinXP (hostname MARK-LAPTOP). Both are connected to broadband via a router. IP addresses for each are determined via DHCP (192.168.1.nn) and I do not leave either on, 24x7. I am running Oracle on MARKUNIX and want to be able to refer to it by hostname when using Oracle tools on my laptop.Each machine can ping each other ok by ip address and curiously the Solaris PC can ping MARK-LAPTOP (I'm not sure how it resolves that?) - importantly the laptop cannot ping MARKUNIX.Now I could add MARKUNIX to my laptops hosts file but that would mean changing the file each time I boot up as the ip address for MARKUNIX will keep changing (DHCP).
Is there a way to refer to MARKUNIX without having to keep changing ip addresses and use DHCP? As I understand it the 192.168 address is private and is not really the 'real' ip address and as such can be manipulated(fixed?) even whilst using DHCP?Am I right in thinking that a static ip from my broadband supplier is the ip of my connection (router) and I'll still have the same private network referencing issues?What I've covered above pretty much is the extent of my knowledge of networking so bear that in mind please.
Ive seen this a hundred times while searching google but I can't seem to get any of the fixes suggested to work for me.
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.
after restarting Apache site is down?
View 1 Replies View RelatedI have a machine with several IP addresses with eth devices like eth0, eth0:1, eth0:2, eth0:3. Can I restart only eth0 without bringing down eth0:1? It would be really convenient to be able to log in via SSH on eth0:1 and restart eth0 without locking myself out or not being able to bring the network back up.
If I stop eth0, will that automatically stop all the others?

I am having a problem in that the Web Server (Apache) keeps stopping. I know this as watchdog is emailing me. Then about 15mins later it starts again. I cannot seem to find why. can anyone give me pointers as where to look to find the issue.
View 1 Replies View RelatedSo far I have came across three options.
1. Watchdog script
2. Daemontools - using "supervise"
3. Monit - open source monitoring tool
From what I can gather, daemontools is probably the best option. Unfortunately, the documentation on the developers site is very vague and I'm having a hard time getting this to work. I think I have it installed correctly, just don't know how to apply it to the service I want monitored.
how to get daemontools to work. All I want to do it monitor a server on my linux box. When it fails, I want it to be restarted automatically.
when it boots it doesn't ask me for my password (not the one to WiFi network, but the one to 'default key base') and because of that I can't connect to my WiFi network. The network itself is working fine. So i restart my computer (sometimes I have to restart it 15-20 times) and finally Ubuntu asks me for my password I type it in and everything works fine. what should I do with this?
View 1 Replies View RelatedHave a domain registered on a public ip. The domain server for the domain is on the same local network as the web server that uses the domain. The web server naturally has a local and public ip address.
The problem is that whenever I try to access the domain from my local network the lookup for the domain fails, as it cannot find the server from the local network. What's the most painless solution to this problem?
TL;DR: need for my domain to be accessible from both my local network and the outside world, now it's only from the outside which is a problem.
Just created a partition to run Ubuntu 10.04. Need to execute an Xcel spreadsheet that requires Linux and a JRE from Java. ATT is my DSL provider, but they do not support Linux, so I have no internet connectivity. I downloaded JAVA 6.0 from another machine and attempted to load it - with no success. Two days of no success! I run OS X and Windows 7, but Linux is new to me. I'm trying, but I'm missing something.

I am using centos with two physical LAN cards. Some times one of our internet link goes down so the entire network stop. Now there are two different ISP internet lines coming into a single computer in their respactive lan cards for load balancing.
Kindly guide me that how can I enable Load Balancing in my Linux Box.
If one ISP goes down the load balancing server will use teh second one and vice virsa.
I wrote a script which sends the server,files from /proc/ like dev,netstat,loadavg etc of a client. i want to calculate the network load and the overall cpu performance of the client using the information from the files.I donot know how to calculate that as i have too many values in those. which values will be useful and how to calculate?

I have Windows 7 on SSD and have installed Ubuntu on a separate HDD.
When the PC boots, I get the boot manager menu, if I choose Windows 7 it fails with error "no such device or partition".
I can mount the SSD and see all the Windows files still there, I think that the boot manager just needs to be pointed in the right direction but not sure how.
