how are nics assigned - eth0 - ethx I am having problem with my distro randomly assigning nic to different ethx after each reboot. Sometimes nice 1 is eth0 and sometimes is eth3.
View 4 RepliesSuffice to say I had a dual boot at work with an essential windows 7 and non-essential linux install on it, and randomly upgrading the distro made windows7 unbootable. Cue a missed days work, much embarrassment and ear bashing from those who are convinced Linux is written entirely by communists and hippies. In the end I had to re-install windows, which cut off the ability to boot to ubuntu - although I've left the existing ubuntu partitions as they were.
Although I can get away with allocating a few partitions to ubuntu, I can't really justify fiddling with the MBR based upon this experience. I need a fast boot and persistent data for doing anything further with ubuntu at work, so I'm wondering whether a safer bet would be to setup a usb stick with enough grub to boot to the existing ubuntu install? Not a full usb distribution, just enough to boot into the existing install? how this would be doneIs it really just a grub-install /dev/sdXX (where XX is the usb)?
I'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.
I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.
My network crashes randomly under regular traffic and more rapidly under high traffic (i.e. running Transmission) and I have to reboot to get it to start working again.

I've read through your forums and done a bit of googling to see that an automated reboot at a certain time has something to do with cron jobsMy second task is then to run commands like the following command when the machine starts up again...screen -t s5 ./srcds_run -console -game cstrike -port 27025 +ip xxx.xxx.xxx.xx +map de_dust2 +maxplayers 11 -tickrate 100 -autoupdateit seems to me I need to edit the rd.local but when I open my file I don't really understand where I need to insert my command
View 6 Replies View RelatedI'm having an issue with dual networking on RHEL 5. My initial question is can the order the ethx (0,1) devices are brought up be changed at boot time, so I could bring up eth1 before eth0?
Some background: eth0 is DHCP'd and using DNS, basically this is my primary network. eth1 is an isolated subnet, with a manually configured IP which has no connection to eth0 or the outside world. When I bring up networking it first brings up eth0 and then eth1, what happens is eth1 becomes the 'primary' network of the host and I lose my connection to DNS/NFS/NIS and the outside world.
If I login and manually bring up eth1 first, then eth0 everyone is happy and connections work. So, I'm looking for a solution to either bring up eth1 before eth0 or somehow make eth0 my primary IP and not have it be clobbered by eth1.
Missing ifcfg-eth[2-5] fileset for ZNYX 345Q Quad Port 10/100 cards. I have showing in the gui network device that my ports for my ZNYX ZX345Q Quad Port card my ports are Auto eth2, Auto eth3 etc. My Motherboard and Intel cards show as System eth0 and System eth1.
There ARE corresponding entries for those in my /etc/sysconfig/network-settings/ directory, but there are not ifcfg-eth[2-5] files to correspond to these adapters. Can I just write my own files and that will do it?
How does Fedora 12/13 load these drivers into the kernel without having these ifcfg files?
I'd love to know if there is another way Fedora controls NICs / other system resources.
I want to make make my fedora machine access-able over the internet. I want to assign IPV4 address to this machine( I already have one IP address ) which can be used for this. What configuration changes I need to make in fedora to make it accessable to the external world
View 6 Replies View RelatedI have a DHCP server running on CentOS and for some reason it is assigning the highest number from the IP range as a first one?
- range 192.168.1.20 - 192.168.1.50 - so the first IP on my PC recived from this DHCP server was .50 - is it normal behaviour?
Config file:
I'm a relatively inexperienced with Linux, coming from a Windows background, and I struggling to solve a troublesome issue attempting to set a static ip address to a Live Debian USB Key. I know it is possible to utilise the 'ifconfig' function to set a static ip address and use 'route' to set the gateway, e.g.
ifconfig eth0 10.0.0.40 up
route add default gw 10.0.0.130 eth0
..however in both cases I need to explicitly set the 'eth0' to point at the appropriate adapter. However, this is where my problem is...
I'm creating a persistent USB key using the Debian Live CD, I'm going to create an image and then duplicate that image to a load of other USB keys. Again, not a problem as such but there are cases where I need to specify a static IP address and gateway rather than using DCHP.
And here's where problem raises its head.
Because I've created the key on another machine it has allocated 'eth0' to a specific MAC Address (assigned in /etc/udev/70-persistent-net.rules) but when I place it into machine with a different network adapter it is assigning to 'eth1' (and this increments up).
a) call 'ifconfig' and 'route' without having to identify the adapter or
b) change the script that is creating '/etc/udev/70-persistent-net.rules' so it overwrites the 'eth0' entry with the only applicavle network adapter for the current hardware.
To get info of all etherhet adapters I am using C as well as info from various files in /sys/class/net/ethx directory.
There is a file name 'type' and has a number in it. Is it physical medium type of ethernet adapter? If yes, then how do I get string representation of that number? If no, then How do I determine physical medium type of ethernet adapter. For example 802.3, 802.5 etc.
new Install of 11.2 every time i boot i have to config network devices via Yast Control Center. I now have 8 eth configs for my one local net adapter. Why does the MAC address change each time? I cant use my routers built in MAC filter and MAC control functions if this keeps changing. So each time i boot i need to also go into my router and build a new MAC address profile based on the new MAC address before i get Internet access. Security to the point of no access...I hope this is just a bug in the system. I thought MAC addresses were firmware/device specific? What I need is one eth config that works each boot. And I need one MAC address that does not change between boots.
View 4 Replies View RelatedDo you know what's relationship between ethx and physical net cards? such as i have three net cards in the PC, named A, B, C. In which config file i could know that eth0 -> A, eth1 -> B, and eth2 -> C. Would the mapping relationship change after reboot? Is there any method i could change the mapping?
View 5 Replies View RelatedI'm trying to write a small script and there's one part of it that makes me sick:
Code:
ifconfig eth$num down
sleep 6
ifconfig eth$num hw ether $mac
ifconfig eth$num up
The problem is that the ethX interface doesn't go down immediately after the first line is executed. So sometimes the change of MAC is called while ethX is up, no matter how big is the sleep time, which results in an error. Is there a way to make this work right?
Running Centos 5.5 64bit. Sometimes I boot this instalation in real machine, sometimas using vmware workstation. The problem is that these environments have different network interface cards - as soon as kudzu detects that network device changed it renames ifcfg-eth0 to ifcfg-eth0.bak and places new default ifcfg-eth0.
Is it possible to command kudzu to leave ifcfg-eth0 as it is ?

View 2 Replies View RelatedSome times I boot up, and udev has labelled what is usually eth0 as eth1. Of course, my rc.inet1.conf is configured for seeing internet at eth0, so no connection, quite obviously. Then I reboot and the device label is back to "eth0". Actually I'm still not able to get connected, even at eth0, despite my nameservers being OK, and the default route gateway being all OK. PS. I have a static ip address.

View 14 Replies View RelatedI have a linux box set up as a multi-purpose server for my home with three Windows client PC's. The linux box is based on a slightly modified Slackware 9.0 distribution using Linux 2.4.20 and an unfortinately old, slow AMD processor with a miserable 512Kb RAM. The linux box serves the CIFS file system to the Windows boxes, runs the SQUID HTTP proxy, the Apache web server, a print server, does masquerading, mail serving and a very effective firewall using iptables.
This system, although slow, has run perfectly for several years.Let me say that again - This system works perfectly.I had decided that now is the time to upgrade the hardware, so I bought a Gigabyte LGA775 motherboard which has two 1Gb network interfaces on it, an ASUS 256Mb PCI-E display card, 2Gb of DDR3 RAM, an Intel Core2-Quad processor and a bunch of 500Gb SATA drives to set up a RAID5 array (but I intend that the system boot off one of several 40Gb PATA drives I have).I set up the processor, motherboard, display card, RAM, a SATA DVD Drive and a 40Gb PATA hard disk in a "breadboard" layout and installed distro 13.1, being careful to set up the static IP for the local network, dhcpcd to get an IP address from the cable modem (my internet connection) and to enable ip_forward in the network configuration.
Then I installed a script invoked by /etc/rc.d/rc.local which installed all the SAME iptables rules as my old Linux box. There was one minor glitch when I had to change 8 occurrences of "-d ! $LOCAL_NET to" "! --destination $LOCAL_NET" but that was no problem. I also set up /etc/resolv.conf, /etc/hosts , the BIND server files etc. etc. exactly as in the old box.
I am able to ping mirror.aarnet.edu.au (this is at the heart of Australia's internet hub network - if it's down the whole bloody thing is down) and have the system find the correct IP from the designated nameservers and contact that server with a return trip time of 35ms. I am able to run a telnet session from one of the Windows boxes and edit files on the Linux server. So both network interfaces work and I've got them the right way around.I am able to run FTP on one of the Windows boxes and connect through to mirror.aarnet.edu.au, although it seems to hang when I try a DIR (but then so does the old linux system).
I am using Fedora 15 64bit (GNOME 3). Everything is working fine and I'm really enjoying the new GNOME but when I use it for let's say a couple of hours, Gnome get's stuck.I'm able to move my mouse and music keeps on playing, but I can't click anything, drag windows or close a window.When I press ctrl+alt+F2 I can still enter a terminal. (by the way, how is it possible that the gnome-shell command uses 99.4-101% cpu without any noticeable lag on my system and a strong processor?)
View 1 Replies View RelatedI'm running Fedora 13 32-bit on a Samsung NC20 netbook (specifications here: [URL]. Everything works fine, with the exception of media playback via VLC and mplayer. The biggest problem is that the entire OS frequently locks up when exiting full-screen playback in either application, and occasionally locks-up when starting playback via mplayer. Video is also always on top of other windows, regardless of whether the application is configured to be always on top.
The lock-ups are severe enough to warrant powering off the machine, as CTRL+ALT+Fx does nothing. I suspect this is related to the machine's VIA CPU/graphics chipset - I've had problems with them before in other Linux distros, but playback was fine under F12 on the same machine. Because the video windows are always on top, I suspect there's a general issue affecting media playback - hopefully configuration related!
I have a Dell studio 15 laptop with 4GB RAM,320GB HDD,ATI Radeon HD 7450 graphics card(512MB) ,Inetl core i3 processor.I am multibooting Fedora 13 with Windows 7.My problem is that Fedora 13 freezes randomly few minutes after booting.Initially,crashing occurred when i was browsing with Firefox,so i downloaded and installed Opera,again the system was freezing.Then i even removed the ethernet cord to check whether there is some problem with ethernet driver.I am trying to use Fedora 13 for running ns2.But,this freezing problem is a big setback.

I'm wanting my ubuntu setup to 'get' it's IP details during bootup, i.e. before login.
This is so that I can logon via NX from my laptop without having to logon via the ubuntu machine first.
Running a LAMP server, CentOS as the OS.The sites always been slow, but now that ive optimized it with mysql cache, gzip compression and some other things, its really fast.Except when pages loading seem to randomly 'time out'. The browser sits on 'waiting for x.com'. Closing the browser and/or the tab and opening a new one fixes it, but then it'll happen again eventually. Clicking further links while its 'waiting for x.com' does nothing, basically the site becomes unusable until you close the tab and reopen it.
This happens on all 3 virtual servers we're running within apache. Mainly noticable on the PHPbb forums, probably because they are visited the most.It's not a slow mysql query, i turned on slow query logging over 2 seconds, and the only two hits i got on that i know are unrelated.Ive turned off some optimizations thinking they might be it, but no dice.
Installed Fedora 12 recently.
For some reason, my network connectivity drops out randomly. This has happened between 5 minutes to 1 hour of booting and logging into the machine.
When the internet does work, its great, and super fast !
When it drops out, Internet stops working, cannot ping to external site and I cannot ping my router 10.1.1.1
I have onboard realtek network ports on my motherboard.
I am running the Nvidia driver. My system freezes randomly. I've had to reboot my system over 5 times today alone. When it freezes, everything is frozen, even the second hand on the analogue clock. One more issue, and I'm not sure if it's related, my stupid screen goes black after 5 minutes of no typing or mouse movement. This never happended when I first installed it. The issue just started within the last 3 weeks. Kpackage Kit is hidden. I was using it to do my automatic updates. Now I just use yum. between the time I first installed Fedora 12 and now, something has happened to my build to cause these issues.
