On my system (OpenSUSE 11.4 - kernel 2.6.37) ifconfig indicates different interrupt number for eth0 than proc aqd sys file system.
ifconfig indicates 17:
proc fs indicates 43:
sys fs indicates 43:
Relevant part of lspci -vv output for irq 17 (this belongs to wlan0 and not to eth0):

For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details. And also this kind of process will have the life time of nearly 1 minute.
Kernel version using: Linux-2.6.18-8.1.8.el5 Is there any possibility of java process without the memory details in the /proc/<java pid>/statm file? If it is possible, how to know the memory related details of that processes?

b) the _tmp NIC is reported in the above Bugzilla report and I'm looking for a patch.
c) Why is the kernel continuing to make NICS for eth1, 2 and sit0?
Just installed a new CentOS with the control panel Interworx. Everything fine, BUT. I can't add new ipadresses cause there is no network device.When i do 'ifconfig' i get the following:

i know this is crazy, but im using a [URL] and have loaded a copy of "red hat linux 7" on the computer. i have no idea what kind of hardware config/spec stuff i should have in my immediate vision, and if i did i'm not sure how i would make sense of it all. linux loaded fine. didnt save drivers. eth0 not showing in ifconfig report, but lo is connecting to network, other host cannot ping linux and vice versus
can mount a cdrom, but not a usb flash dont quite understand how the load methods work involving /mnt/cdrom/"usbutils-0.86tar.gz" eth0 problems and gnome rpm stupidity keeps me from upgrading sys from old version to a newer version, cant even find the cmd to show me that info, sorry. have usb files i want to mount, dont know how to loAD THE CDROM FOLES, SO EVEN THAT ISNT WORKING OUT HAVE DISCS WITH howtos just need to stay focused on steps to get desired end result, while trying to learn too much info for what im currently doing between all the f!@#@ing windows i have open.
Program code as how to measure interrupt latency..

I checked the manpage for rm, but there's no metion of the inode number. Doing rm inodenumber doesn't work either.
What is the command for this?
I have a problem with the network. Worth two network cards and Ian wan. Do not take the ip. When the system boots not included until you do the command ifconfig eth0 up. The network card is connected to a router, he does not see it. Router working, tested. Network card is working well, tested on Windows. RX RT packages go, withheld support for ipv6 and packages no longer go.

I have been noticing a trend on boxes running 11.4 getting RX dropped packets where prior to 11.4 they did not get them. Basically every box running 11.4 now logs dropped RX packets. Have tried changing cables, and in one case replaced the NIC with a different brand (and driver) nic. Also played with receive buffers and yet the counters still increment. In addition to OpenSUSE, I run several operating systems to include Centos, Scientific Linux, Debian, OpenIndiana, HP-UX, VMS and so forth. So far this anomaly has only shown up on machines running OpenSUSE 11.4. Any one else noticing this on your OS 11.4 machines? If so, were you able to resolve?

I'm trying to get my Ubunutu and OSX systems to connected via a cat5 cable to transfer some large files around very quickly. Now i know normally this would require a crossover cable as it's a direct connection but the macbook/OSX can handle changing the wires round to make it work like a crossover cable as I've done it before. However the macbook creates a self-assigned IP or as I've tried I've set it to :
IP:10.10.0.1
Subnet: 255.255.255.0
Then I've setup the Ubuntu system both through the System>Admin>Network panel as:
IP:10.10.0.2
Subnet: 255.255.255.0
and my /etc/network/interfaces file is the same;
#lines added to get static crossover cable working
auto lo
iface eth0 inet static
address 10.10.0.2
netmask 255.255.255.0
Yet when I run ifconfig in the terminal eth0 isn't present
Code:
htpc:~$ ifconfig

Also even when I try and ping 10.10.0.2 either from my OS X or the actually Ubunutu machine all I get is:
Code:
ping 10.10.0.1

Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
Yet the Ubunutu machine is also connected to Wifi and when I ping it's own address I get the expected response. To me it just seems like eth0 isn't being recognised somwhere or it's not turned on yet I can't seem to find any toggles or settings for it anywhere. Further more if I check >System>Admin>Network Tools the IP for eth0 is 0.0.0.0. What could be going wrong and why no IP set correctly?
I've got a vmware install of Fedora 12 running as a server. This install has the /etc/sysconfig/network-scripts/ifcfg-eth0 file configured with the proper info and the service has been restarted. When I run ifconfig I only get the loopback interface, when I run ifconfig -a I can get the eth0, but without the pre-configured ip address. When I enter ifconfig eth0 up I can activate the interface, but without the afore mentioned ip address. I need to be able to yum ssh, install it, and run it with rsa keys. Can do none of this without an interface obviously.
View 3 Replies View RelatedI'm trying to grok a problem I'm having with an embedded machine. I'm pretty sure I can track down the larger problem, but I came across a usage of ifconfig that I don't understand, and I'm pretty sure this is the command that is failing.
The command is: ifconfig eth0 192.168.78.20:9134
I understand how ifconfig works. What I don't understand is the :9134. I can't see anything in the docs about what this means. I know in most contexts it's a port number, but what does it do when bringing up a network interface? Does it limit it to only using port 9134?

A network client computer gets ip address from dhcp server, loads initrd and failed on Loading Istallation System stage 4 or 5. If I try to continue installation in manual mode I get an error net_activate: ifconfig eth0 up failed I tryed network cards from different vendors it did not help. Ubuntu linux installs successfully in current environment.
i have a problem. I cant find anything except my mac address if i type "ifconfig eth0" in terminal.There is no gateway adress ip adress and netmask. This is wierd. How can i asssign those to a eth0?
View 1 Replies View Relatedexplain the difference between these two commands. I'm currently reading about changing your mac address and both of these commands show up a lot. They sound like the same thing to me. Is one better than the other, or do you need to use both to change your mac address?
Code:
sudo ifconfig eth0 down
sudo /etc/init.d/networking stop
When I try execute a variety of basic commands (including ps, ls, ifconfig, locate), I receive the error 'no such file or directory'.
Here are some suggestions that I've found online, that I have tried without success: I did a 'whereis ps' and found the file in the /bin/, and have checked that '/bin' appears when I do 'echo $PATH' I did a filesystem check which showed my hard drive as being clean I tried doing a 'sudo chmod 777 ps' but was told that I dont have permission. I don't think permissions for these files would have changed though (and I can't check as I can't run the 'ls' command).
algorithm:breada
input: file system block number for immediate read
file system block number for asynchronous read
output:buffer containing data for immediate read {
if(first block not in cache) {
get buffer for first block
if(buffer data not valid)
initiate disk read }
if(second block not in cache) {
get buffer for second block)
if(buffer data valid) //line 1
release buffer else
initiate disk read //line 2 }
if(first block was originally in cache) //line 3 {
read first block
return buffer }
sleep (event first buffer contains valid data)
return buffer }
Here is an algorithm for block read algorithm. I have problem in
line 1: If buffer data is valid why is it releasing the buffer?
line 2: If buffer data valid why is it initiating disk read. It should have read directly from buffer?
line 3: It should be the first condition as if it is there in cache then it should return it without delay?
I have random crashes since I upgraded from Fedora 11 to Fedora 12.I searched the internet to try to find the root cause of the problem.I created this bug report:URL...However, no comments were added how to solve the problem.Enabling msi for nvidia and hda-intel made the system much more stable. But I still experience sometimes crashes.I do not know how to enable msi for uhci_hcd:usX, which is still sharing interrupts with ata_piix and ehci_hcd:usbX.Have you some hints? I hate it when my Fedora Linux system is crashing randomly.

filesize=$(awk 'END {print NR}' $1)
but as for inserting this into the first line, i'm failing to do so. I've tried some of the other approaches on these forums but none so far have been able to do so.
I've tried:
sed '1i$filesize' $1

mv "$1" "${1}.bak" 2>/dev/null || touch "${1}.bak"
cat $filesize "${1}.bak" >"$1"
but again with no luck as cat seems to need an input stream Just to recap, i want to insert a line at the start of a given file that holds the number of lines the original file has.
ie the file:
