The system will also crash when booting if it is not plugged in. However, this behaviour is not consistent. 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.

On restarting networking service, i am getting the following error,
Code:
karthick@karthick:~$ sudo /etc/init.d/networking restart
* Reconfiguring network interfaces.. ssh stop/waiting
ssh start/running, process 5427
start: Job failed to start
[ OK ]
I use red hat linux. When I start up network service. I get below error in eth2
root@vls etc]# service network restart
Shutting down interface eth2: [OK]
Shutting down loopback interface: [OK]
Bringing up loopback interface: [OK]
Bringing up interface eth2: RTNETLINK answers: File exists
Error adding address 10.1.1.82 for eth2. [OK]
I paste the ifcfg-eth2 in here
[root@vls network-scripts]# cat ifcfg-eth2
# Intel Corporation 82572EI Gigabit Ethernet Controller (Copper)
DEVICE=eth2
BOOTPROTO=none
BROADCAST=10.1.255.255
HWADDR=00:80:82:8F:B4:A2
IPADDR=10.1.1.82
NETMASK=255.255.0.0
NETWORK=10.1.0.0
ONBOOT=yes
GATEWAY=10.1.1.249
TYPE=Ethernet
USERCTL=yes
IPV6INIT=no
PEERDNS=yes
So, what is the problem of error adding address?
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.
So 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.
If I restart the network service, not all interfaces come back up. Is this expected behaviour or does something need a kick?
Code:
[root@@aspire3500 ~]$ service network restart
Shutting down interface eth0: [ OK ]
Shutting down interface wlan0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
[root@@aspire3500 ~]$
I use fedora 14 and when I'm trying to run the network service on my system it gives me the following error -

Shutting down loopback interface: Error: Device 'lo' not found. [FAILED]

Ubuntu desktop 9.04 Whenever I try to copy files to any machine on the network, the transfer stops and I no longer have access to the network or the internet. 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.
View 1 Replies View RelatedIt 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.

View 1 Replies View RelatedI just did a yum upgrade from F13 to F14 to F15. According to /var/log/messages NetworkManager crashes trying to parse a VPN keyfile:
Code:
NetworkManager[2519]: ifcfg-rh: parsing /etc/sysconfig/network-scripts/ifcfg-eth0 ...
NetworkManager[2519]: ifcfg-rh: read connection 'System eth0'
NetworkManager[2519]: keyfile: parsing VPN Connection UDP ...
NetworkManager[2519]: <warn> caught signal 11. Generating backtrace ...
I'd like to remove this VPN config in hopes that NM can init and run, but I cannot figure out where this configuration is stored.
I was running F15 for a month now. After this week's updates NetworkManager crashes at startup and throws a backtrace. During reading ifcfg-<wifi network name> it was throwing some assert() failed of some hash is not null, but just as a warning. Later it was dying while reading ifcfg-eth0.
I removed all the ifcfg-* files in /etc/NetworkManager and /etc/sysconfig/network-scripts
Then NetworkManager started but at the moment I used the gnome applet to connect to a network it crashed trowing a backtrace (I have no debuginfo installed).
Then I also deleted ifcfg-* in /etc/sysconfig/network/profiles/default and /etc/sysconfig/network/devices, now the NetworkManager does not crash anymore, but instead gnome applet crashes when I try to connect to a network. grrr...
As a result I am still unable to connect to any network. Why so many copies (hardlinks?) to these config scripts? Now it is even worse: I rebooted the system and at the boot time when NetworkManager starts the boot process freezes. It says in VPN the Get() method is not implemented. I am unable event to switch a console and to log in to put the config files back (getty not started?).
I've not changed my configuration, but after temporarily unplugging my laptop from the router, I can no longer persuade it to connect again.Have restarted it repeatedly, but to no avail.A similar problem has been occurring with my Huawei 3G Dongle which has suddenly started behaving.Are there any troubleshooting guides for the Network Manager's wired connections? Don't know where to start.

View 1 Replies View RelatedI have recently installed CentOS onto an old machine to get it up and running as a basic web/mail server. Originally the Network Interface worked ok, however I have been editing /etc/sysconfig/network-scripts/ifcfg-eth0 to try and set the IP address to be static.Now when I run the 'service network restart' command it won't bring the eth0 interface up and comes up with the following errors;
ifcfg-eth0 Line 3 DEVICE: command not found
missing config file ifcfg-ifcfg-eth0
It doesn't seem to like any of the command words, even though most of these were in the original file that worked and the ones I added to do static I have commented out.
I have been suffering a connection problem with one of my VPSs recently and I really just can not seem to figure out what is causing the issue. First of all the issue only appears to hit my home computer/network and not other people, it might sound like a routing issue but it doesn't appear to be so. When I am hit by connection issues, I can resolve the issue by logging into Dom-0 (all other VPSs are also available) and consoling the offending VPS before running "service network restart". I personally can not think of anything that would require the network service being restarted and only hit myself (and only at home on top of that).
The VPS itself is dedicated to running minecraft server and is using CentOS, when it occurs I can not SSH the server either, all other ports and methods are disabled by firewall (iptables appears to have no effect in regards to this issue either). Fundamentally I am just thinking if anybody could think of any reason the VPS would only refuse connection to myself that restarting the network service would fix. A few other notes, the physical Server is hosted within a Datacenter, running 24/7 with a static IP. No other VPSs hosted on the machine have any such issues, the machine appears running normally via console and has no visible errors or logs that I know of reporting any issues that could be causing this.
I installed Fedora Core 12 on a Dell Latitude 610 laptop. Networking isn't working. I tried to start networking with '/etc/rc.d/init.d network start': there were no errors or warning messages, but before and afterwards, I could not ping anything.
I tried to configure and start networking with system-config-network. The ethernet network card shows up, but the activate button is greyed out.
I can ping the loopback address 127.0.0.1 after I start networking with '/etc/rc.d/init.d network start' but I don't really know what that means.
lspci tells me that my network "card" is a "NexXtreme BCM5751 Gigabit Ethernet PCI Express".
I know the eternt cable is good because I used it on another machine.
I addes IPv6 address to my interface as
Code:
ifconfig eth0 inet6 add 3fff:ffff:6:5:4:3:2:1
But, when I restart the network service this IPv6 address is gone. How could I make it as a permanent IPv6 address( that should be edited or deleted when I want but not when I only restart the network)to my interface?
I have a tricky problem which I could soIve with a c program. I wrote one and found I didnt have gcc so I tried to install it. I was told I needed to install packages. I acknowledged and an error was generated gcc-4.4.2-7.fc12.i686 requires libgomp = 4.4.2-7.fc12 I try to install libgomp and go round again.
View 2 Replies View RelatedSo whenever I turn on my EeePC with Ubuntu 10.04 on it, the network crashes after like 10 minutes to 45 minutes. Every time. Of course I have that horribly <snip> bug where the WPA and even WEP on my laptop are buggy because of 10.04, but it did the same when I was on 9.10 (but like 3-4 times a day instead of many times an hour).
Yeah, so when I connect to the network with my laptop, the network crashes. The wifi still works, I can detect the wireless network on all my computers (my Ubuntu one, Windows 7 and my girlfriend's Mac), but internet does not work. I then have to turn off router/modem, and it starts to work again. Then, a couple of minutes later, if the Ubuntu laptop is on, it stops again.
That's annoying because I can't really use my laptop on the internet because I'll have to restart everything soon. I've tried setting to WPA and to WEP and it happens with both. Same goes if I set my laptop to a manual IP address or an automatic one. I did some tests to be sure, and the network works without crashing for days if my laptop is closed, so the problem really is with Ubuntu, and as I said, it kind of always did that, but it was tolerable before.
I have recently installed Centos 5.4 on a server with 3 network cards. I am trying to enable IP forwarding which has been successful by executing the following command:
echo 1 > /proc/sys/net/ipv4/ip_forward

When I restart the network service I get the following code...

View 1 Replies View Related"Dell 1525 WLAN PCIe card with11n mini-Card & external antenna" wireless card. It got recognized fine by FC12, but it was rather slow. I had read that life would be better in FC13 with the new kernel. After a long wait, I upgraded to FC13 yesterday.
It seems that the wireless is indeed faster. However, it it clearly a lot slower than under Windows 7 (it is a dual boot PC). My test is simply to play say Hulu in full screen: under Windows it looks fine, under FC13 it plays in slow motion.
whats the difference between restarting/stopping apache using 'service httpd restart/stop' and apachectl restart/stop. I know that using 'service httpd restart' is actually a script in /etc/init.d/httpd but what about apachectl?
