General :: Fedora Ethernet File Locations For Auto Eth - X - Devices Missing Ifcfg-ethX Files

Jul 24, 2010

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.

Red Hat :: Prevent Kudzu From Changing Ifcfg-ethX File?

Aug 31, 2010

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 ?

Red Hat / Fedora :: RHEL 5 Dual Networking - Ethx (0,1) Devices Are Brought Up Be Changed At Boot Time

Jun 3, 2010

I'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.

Server :: Missing Ifcfg File After Replacing Nic?

Jan 5, 2011

I have 2 10gb fiber cards on a server running red hat 5.3, eth4 and eth5. After replacing the eth4 card, it doesnt show up any ifcfg-eth4 file. I tried ifconfig -a, but it doesnt show up in modprobe.conf either, although it is listed when I do a lspci. Should I manually add it? or is there something Im missing here?

General :: Auto-mount Virtual Machine Locations When VMware Image Finishes Loading?

Jun 20, 2011

I mount a few locations from a VMware virtual machine, but currently every time I start up VMware I need to re-mount the locations once the VMware image has started up fully, which gets tedious. I'd like to be able to mount them automatically when VMware is started.

I generally double-click the .VMX file (which is associated with VMware Player) to launch the virtual machine, but once it has finished loading I would need to run the mount commands manually or execute a bash script that does it.

Is there any way you can think of to have it done automatically? One way I can think of is to start my virtual machine by running a script that starts VMware player, sleeps for a minute or so, then runs the mount command - but setting the right sleep interval would be difficult because this varies a fair bit - and overall, it's a solution that's kinda icky and that I'd like to avoid if there's some better option.

Fedora :: Wireless Unavailable / No Ifcfg-wlan0 File?

(and new-ish to Linux in general) and would appreciate some assistance with fixing a problem I'm having with getting wireless working on my computer.Computer specs: Lenovo Thinkpad Edge 520, I5Wireless card: Intel WiFi Link 1000 b/g/n(Note: I also have a Netgear USB wireless adapter, and trying to use this does not solve my problem)I cannot activate wireless. When I go to Network Settings > Wireless, it is listed as "unavailable", and "off". When I try to switch wireless "on", it says "disconnected", but then immediately switches back to "off".Having tried to browse various forums and such for a solution, I tried looking for the file ifcfg-wlan0 under /etc/sysconfig/network-scripts, but it doesn't exist

Hardware :: Data Storage Locations Of The Separate Devices Involved In Booting Requested

Oct 18, 2010

I'm trying to get a complete overview of booting so I can multiboot. An explanation of the hardware that stores data and the hardware that runs it with the paths the data takes would be awesome!

Here are some quotes that are not comprehensive.

Quote from [url] "When the processor first starts up, it is suffering from amnesia; there is nothing at all in the memory to execute. Of course processor makers know this will happen, so they pre-program the processor to always look at the same place in the system BIOS ROM for the start of the BIOS boot program. This is normally location FFFF0h, right at the end of the system memory. They put it there so that the size of the ROM can be changed without creating compatibility problems. Since there are only 16 bytes left from there to the end of conventional memory, this location just contains a "jump" instruction telling the processor where to go to find the real BIOS startup program."

System Memory is your RAM is it not? Why are they being specific in stating the address location in the Firmware that BIOS uses? An external EEPROM on the board is totally different from RAM is it not? Does the BIOS data travel to a specific RAM Location?

Is there a small processor connected to BIOS or is everything run with the Main CPU?

What exactly is the "chipset" that is referred to with booting?

Networking :: Ethernet Auto-connect / Auto-sense Doesn't Work

Feb 3, 2011

I have noticed that a common issue to several distros is the fact that the networking subsystem doesn't automatically detect the link if an ethernet connection is disconnected and then re-connected to the NIC after boot. If the ethernet cable is connected after the system is up and running, nothing happens - ethtool eth0 shows link detected: no, and you have to restart the network service to let the NIC know that there is in fact a link, and actually connect. I have a Fedora14 (KDE) box with a brand new Asus motherboard with embedded NIC. Everything works great except the auto-detect of a freshly connected ethernet connection if the link is down to begin with.

Am I missing a ethernet link sentinel utility or something, or is this just the way linux works? I have done plenty of research on plenty of posts, and it seems this is a common problem, with no solution other than manually or programatically restarting the network service in a script to detect the link after a disconnect.

Fedora :: Missing /etc/sysconfig/network File And Eth0 And Wlan0 Files?

Oct 31, 2010

I just installed Fedora 13 on a new Dell XPS desktop and some of the networking files are not created/missing. The computer has Broadcom Gigabit wired card and Asus PCE-N13 wireless card. When I type lspci, I see that Network conroller: RaLink RT2860 and Ethernet controller: Broadcom BCM57780 Gigabit Ethernet. So, somehow they are being detected by the OS, but I am not sure if the drivers are installed or why some of the network files are missng.

Fedora Networking :: FC11 Not Auto Detecting Ethernet Interface

Jun 10, 2009

On FC10, when system boots up, it would auto detect (from DHCP) and configure eth0.

This does not happen on FC11, but I can manually configure the interface. The entries in /etc/sysconfig/network-scripts/ifcfg-eth0 are identical on both OS releases.

Don't know if this is related, but when I run System->Administration->Bootloader, it fails system-config-boot - missing module kudzu.

General :: Download A Single File In 2 Parts To Different Locations Using Wget?

Jan 18, 2011

I need to use wget (or curl or aget etc) to download a file to two different download destinations by downloading it in two halves:

First: 0 to 490000 bytes of file
Second: 490001 to 1000000 bytes of file.

I will be downloading this to separate download destinations and will merge them back to speed up the download. The file is really large and my ISP is really slow, so I need to get help from friends to download this in parts (actually in multiple parts)

The question below is similar but not the same as my need: How to download parts of same file from different sources with curl/wget?


aget seems to download in parts but I have no way of controlling precisely which part (either in percentage or in bytes) that I wish to download.

Extra Info

Just to be clear I do not wish to download from multiple locations, I want to download to multiple locations. I also do not want to download multiple files (it is just a single file). I want to download parts of the same file, and I want to specify the parts that I need to download.

Fedora Networking :: Create A File Like "ifcfg-eth0:1" And Put Contents?

I am having a problem when creating alias in Fedora Core 10. When i create a file like "ifcfg-eth0:1" and put contents in it like

IPADDR=ip addrss

and when i save settings and restart with "service network restart" the network card does not create any alias like eth0:1 instead it replace the original ip address of eth0 with the ip address i given to eth0:1. So i want to keep both network ips of eth0 and eth0:1.

Networking :: RedHat 5.4 Bonding - Modprobe.conf * Ifcfg-* Files Involved

Aug 5, 2010

I'm trying to do some network bonding in RHEL 5.4, and I'm not seeing the results I expect. I have set up a number of servers using mode 1 with no issue, but I need to configure a new server differently. bond1 is created from eth1 & eth2 bonded together using mode 802.3ad with layer2 lacp bond0 is created from bond1 & eth3 using mode active-backup with bond1 as the primary interface When I bring the network services up, all traffic is passing over eth3 instead of bond1, which is the primary. Below are the modprobe.conf * ifcfg-* files involved.

My modprobe.conf:
alias eth0 e1000
alias eth1 e1000
alias eth2 e1000
alias eth3 e1000
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptsas

General :: Missing Eth0 Ethernet Interface In Ubuntu — Can't Connect To Router

Aug 27, 2011

I'm having trouble getting my Ubuntu 10.04 machine (Sony Vaio VGN-SR490) to connect to the Internet by way of an Ethernet cable connected directly to my router.

I'm able to connect to the Internet using this same cable using a Windows machine, so there's something wrong with the way Linux is configured.

How do I got about figuring out what the problem is and solving it?

Here are my network settings on Linux:

$ ifconfig
lo Link encap:Local Loopback
inet addr: Mask:
inet6 addr: ::1/128 Scope:Host


It looks like the network adapters list is empty. I will now install both Windows XP and Ubuntu Linux dual-boot. I'm still not able to access the internet, even through Windows. I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine. (That's how I'm posting this after all!)

General :: Using Ifconfig Without Using 'ethX'

Jul 1, 2010

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 up
route add default gw 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.

CentOS 5 Networking :: NIC Card And Config Won't Come Up In The Ifcfg-eth0 File?

Mar 18, 2009

I've been racking my brains over the past few days trying to figure out why my NIC card (network interface card) won't show up in the ifcfg-eth0 file.When I configure a new server (like this one) I always go to:/etc/sysconfig/network-scripts/ifcfg-eth0 and from there I usally see the name of my NIC's manufacturer's name and the hardware MAC address.Then it's only a simple process of entering the server's IP address, netmask and gateway and I'm up and running in no time...But not in this case! the ifcfg-eth0 file is completely blank! There's not ONE single line of config info in it... (?)The server runs an Intel core 2 duo (dual-core) CPU with 1 gig of RAM.

I've even re-formatted the drive and re-installed Centos 5.1 on the darn thing 3 times and it simply won't work.The server cannot resolve when I do a wgetIt also gives me a 'resolution problem in the named configuration'.What I don't understand is that the 2 small LEDs on the Cat 5 cable lights up and flash at what appear to be regular intervals here.

There seems to be at least two ways of doing this: Would the 60_net.rule file override a 010_netinterfaces.rules file because it gets executed later, or would the 010_ net interfaces. rule file set up the info in /sys which would then be used by 60_net.rule?
