I 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 was wondering if it were possible to add devices to my computers /dev folder over a network. In linux philosophy, everything is treated as a file, and if I can have my /home/user1 and /home/user2 folders located somewhere on the network, why not the devices in /dev? The idea is that I might control, say, a cd drive in another computer or, a monitor on another computer. Can anyone give me some thoughts on adding devices to my /dev folder over a network? The aim is to make something evil of course! (like a 10 monitor PC)

I have two network interfaces
Infiniband network and the Ethernet network.
It is a x6275 Sun server.
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!
On restarting networking service, i am getting the following error,
Code:

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 use red hat linux. When I start up network service. I get below error in eth2

So, what is the problem of error adding address?
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.
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.

View 3 Replies View RelatedJust installed 11.3 kde. When running the live cd both wireless and ethernet devices appeared in the network connections manager utility. I even connected to a wireless AP.I just booted up for the first time and none of these devices are available. There is no network manager icon in the system tray, and when the network manager utility is maually opened the only connection type i can select is vpn.I know that opensuse should be able to recognize these devices since they were available and working via the live cd, so can anyone help me restore them?
One extra piece of info, is that I am sharing a home directory with a gnome ubuntu install. there were a few minor issues i dealt with initially, but i didnt need to change this user's UID like I have had to do in the past so that's good. Each time i open a terminal I get two pieces of output assuming from the bash startup saying something like.URL...I highly doubt that these problems are related, but figured I'd post. Also if someone knows the solution to that as well, that would save me a bit of googling.
Small home network consisting of a media server(headless, no monitor/keyboard/mouse)running OpenSuse 11.0, and 3 Windows clients running Vista. I don't need the server running 24/7 so I have it set to Suspend to Ram after 60 minutes, which works great. I have a WOL program on each client which works perfectly to wake up the server.
However, there are times when the server "sleeps" while I'm still using it. I can be downloading to the server, playing music, or whatever-doesn't really matter-and when the 60 minutes is up, it sleeps. What I need is some solution that will keep the server awake if I'm actually using it but let it sleep after the specified period of inactivity. My first thought was using Ethtool to wake it network activity directed at the server, but I've tried all the ethtool options and can't make it work right. Either it wakes on any network activity whatsoever, (which means it never sleeps) or doesn't wake at all.
I administrate a network with approximately 140 PCs. They all have Ubuntu and I want to be able to turn them on and shut them off remotely from one of the servers. So can you tell me what is the best way to do this ? A shell script would be a nice option if its possible.

I was wondering if anyone had any issues with this. I recently tried installing CrunchBang and it got stuck while detecting the network device. (Would not recover)I had the same issue when attempting to install the Debian Testing release. I finally got Testing up and going but I had to start with Squeeze and then upgrade. Unfortunately I don't see how I could do that with Crunch Bang.
I tried the live cd of CrunchBang and found it to be a great minimalistic approach to a desktop.
Does anyone know or recommend some software or a script to remotely power on a PC from standby to on, or even better from completely off?
I guess the completely OFF to ON is much more complicated - would probably require an extra piece of hardware(?)
I'm not terribly new to Linux, but I am new to the forums, so hear me out! I am in the process of creating an electronic mapwall for our meteorology program, and have designed the computing system from scratch. I have two Linux Boxes, each with capabilities for 6 attached monitors...a total of 12 displays driven from two machines. My intention is to have one machine be the master...it has a touchpanel control. The inputs to the touchpanel will then trigger events for the both the master and the slave machine to display. Each of them has a specific IP address (DNS entry), and are not on a subnet.
Now...is there a way to remotely login to the slave machine and have it display on it's OWN monitors? The code is Java and which works on the master machine to animate directories of .gifs for each of the master's attached monitors. I will most likely have Java execute shell commands for the remote login (ssh), but I believe the answer lies somewhere in the X-configuration. Do I have the machines in an adverse configuration (creation of a subnet would be better)? Lots of questions...lots of desire...few answers!
Is there a command to remotely shutdown a computer on the local network? I have a computer running as a file/print server and I have no screen or keyboard connected to it. Would be great if I could shut it down from my laptop. I have the needed credentials (as I'm guessing these would be needed in the command?)
