I have a remote control (imon --> Harmony) that acts like a mouse. My goal is to remove that feature. Iam using lirc with Linux input layer (/dev/input/eventX) because Imon driver doesn't work at all. To get Linux input layer to work you need to choose the imon device.
Code:
cat /proc/bus/input/devices

When I connect my Treo 650 with a USB cable it works sometimes and not others. A little investigation showed
that it always works when I see the Palm device listed in the output of lsusb. While trying to diagnose why it appears sometimes and not others, I discovered that it sometimes appears in /proc/bus/usb/devices and not
in lsusb. I didn't think that was possible!
I've tried running kudzu (the Red Hat hardware discovery tool) and killing and restarting udevd.
I want to know that is there any command by which i can check which type of hardware devices are installed in my Linux box like SVGA,Sound Card,LAN Card.

I'm trying to track down a problem with a utility that used to work and now hangs indefinitely. Since its hanging, I suspected a locking problem, and went to have a look for the process ids in /proc/locks; I get:
148: FLOCK ADVISORY WRITE 30279 ca:21:49153 0 EOF
148: -> FLOCK ADVISORY READ 30282 ca:21:49153 0 EOF
Now as near as I can tell this shouldn't be my problem, since the two ADVISORY locks - one READ and one WRITE - shouldn't conflict with one another. But I'd like to understand it all the same. I haven't been able to find any kind of definitive guide for the format of /proc/locks entries, but what I did find in the manuals specifically states:
"Each lock has its own line which starts with a unique number. "
Which is obviously not true; both of my lines start with the same number. Also, since most search engines don't seem to play nicely with symbols, I can't find any reference to what the "->" means.
I am currently writing a JAVA script to monitor certain unix processes through JConsole. Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.Now i can pull back any information from any of the files I want, and the current way i determine the CPU usage of a process is as follows:
Add the UTime and STime of that process from /proc/pid/stat then divide my pidCpu by UTime + STime + NTime from /proc/stat, then multiply that by 100, should give me the % cpu usage a process is using, right?Theory being if I get the jiffies assigned to my process, I can divide that by the total jiffies the cpu assigns. However, my results seem to vary from the ones gathered from top and ps. What am I doing wrong?

i had some issue with the machine rebooting multiple times, What happens is that the machine boots up and suddenly crashes and then boots up cleanly. I was going through the log files during when this occurs. I came across /var/log/syslog which i guess logs messages before shutdown. It has following messages which i think are causing problem.
Could not open /proc/26694/stat: No such file or directory
Could not read the file /proc/26694/stat
Could not open /proc/31128/stat: No such file or directory
Could not read the file /proc/31128/stat
Does any one know what these messages are?
I'm working in CentOS 5.4 with the default 2.6.18-164 kernel (which I will be editing but have reverted back to in order to solve this problem.)
Near the end of the init script I have thrown a /bin/sh to get into a busybox bash shell in order to test some scripts. Ive attached the init below.
While in this shell I can see my usb drive in /proc/bus/usb/devices and my hard drive in /proc/scsi/device_info however I cannot mount them as they are not in /dev.
I have scsi emulation set in the kernel. When I plug in a USB stick it finds the address but still no sign of it in /dev. There are other modules listed in /sys/module such as usbcore that dont show up in lsmod, is that possibly the problem?

View 2 Replies View RelatedAs I understand it, setting /proc/sys/vm/overcommit_memory to 1 is supposed to make sure malloc always succeeds, and set the OOM killer loose if there's an actual memory problem.
I'm wondering what happens when you've malloc'd so much memory that you've exhausted the address space for your process? Does it return NULL despite the overcommit_memory setting, or does your process get a signal? Or something else entirely?
I have a script that needs to extract certain information form the /proc/net/ip_conntrack file once in a while. I do not wish to run this script as the root user.

There is a computer with two "Xeon(R) CPU X5550 @ 2.67GHz" CPU. The Hyper-threading is enabled, so it looks like 16-core system, but really there is only 8 physical cores.
I know that when hyperthreading is enabled, each physical core is splitted into two virtual cores. I want to know, which pair of virtual cores shares a physical core and which are not. Or, how (in what order) will Linux enumerate HT-cores comparing to real cores. (enumerating is done for sched_setaffinity and taskset masks).
I have a dump of /proc/cpuinfo file from the system.
I think there are possible:
CPU0-CPU7 are not sharing phys. core. CPU8-CPU15 too. But sharing is in pairs CPU0+CPU8, CPU(i)+CPU(i+8) and so on. or CPU0+CPU1 are from single physical, CPU2+CPU3, CPU(2*i)+CPU(2*i+1). or exotic CPU0+CPU15 sharing, CPU1+CPU14 ... or random?
The hard moment in this case is that there are 2 physical dies of CPU (two sockets), and usual recommendation of using "physical id:" field can't help

processor : 0
vendor_id : GenuineIntel

To get the kernel messages of new java process, i refer the details from /proc/<java pid>/stat and /proc/<java pid>/statm files. 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?
I am tired of watching fsck check my filesystem when my eeepc 901 shuts down abruptly due to a crash. I know that with a journaling filesystem, I won't have to wait for a check. However, I am well aware of the poor I/O performance of the SSD, so I can imagine using a journaling filesystem being even more frustrating, since there will be constant writes to the journal? I will buy a new laptop without such a crummy ssd someday but, is there anything I can do now, on the software side of things?

Looking to get some input on finding a distribution to move to from Ubuntu.Overall, there's some changes--mostly unimportant overall, but stick in my craw--on the horizon, and I'm looking for alternatives. I'm a casual user, only one using my machine, don't need anything extra-special...something that isn't extremely utilitarian from the get-go, and doesn't come loaded with a boatload of things I'll never use. I enjoy putzing around in a CLI, and I'm not opposed to having to get used to slightly different commands when using it (though I expect that, on the whole, most things will be the same).I know, a little vague on what I'm looking for...best put, a stable system that doesn't require me to do TOO much, but lets me do what I want even if it means breaking things every once in a while.

What are the alternatives? If there are no full solutions - I propose the unification of several partial solutions into a merged FOSS project. I recommend a secure chat/video client with SIP capabilities and native ports for Linux Console, X, and FreeDos.
I like how iftop shows at a glance and in real time where my bandwidth is going. It requires root privileges, however. Is there a similar command or tool that a regular user can use to visualize bandwidth use? Say the kind of user who shouldn't be given the keys to the kingdom?
