Ubuntu :: Create /proc/bus/usb In 10.10
Dec 18, 2010
I am trying to use eciadsl in ubuntu 10.10 in order to connect my Prolink H9601 USB ADSL modem(Conexant based) to the internet.eciadsl worked to some extent in ubuntu 9.10 but in ubuntu 10.10 it returns [EciAdsl 1/5] Setting up USB support...
I presume this is because ubuntu 10.10 does not mount USB device filesytem (usbfs) in /proc/bus/usb folder and i can't manually create this folder therefore making it impossible to mount usbfs manually into this folder.

I've got the F13 LiveCD that I was able to boot and use using the "nomodeset" boot option. From the desktop I'm trying to perform an Install to Hard Drive. I've read the Install from LiveCD post regarding the creation of a /boot partition and a / root partition. I've tried creating them without the LVM group and with. But every time I appempt to install I get...
An error occurred mounting device proc as /proc: mount failed: (9, None). This is a fatal error and the install cannot continue.
Hardware is a Sager 8887 (P4, 3.06HT, 60GB HDD, Radeon 9000 graphics adapter)

I want to know how much time the computer is performing IO read/write during a time interval, so that i can compute the percentage of time spending on IO. I look at /proc/diskstats, and notice that there are these fields:
Field 1 -- # of reads issued
Field 2 -- # of reads merged, field 6 -- # of writes merged
Field 3 -- # of sectors read
Field 4 -- # of milliseconds spent reading
[Code].....
How can this happen? I thought the maximum value of the read and write time should not exceed the total time. Am I doing something wrong? Are there any other methods to get the disk IO time?

How do I change permissions to open /proc/1 thru all/fd at once? In my case, that would be 1 thru 3357

I have a rather ancient build environment where I switch into using chroot. The script looks like this:
Code:
echo 0 > /proc/sys/vm/vdso_enabled
echo 4096 > /proc/sys/vm/mmap_min_addr
chroot `pwd` /usr/bin/env -i
HOME=/root TERM="$TERM" PS1='[CR]u:w$ '

I recently installed a newer kernel to get the open source driver for my ATI card, but am now getting the following error between booting and logging in: Warning: unable to find suitable fs in /proc/mounts. Is it mounted? After doing some research I can see it has something to do with apparmor. My questions are:
1. Can I somehow get rid of this error message? Or rather, is there a solution for this problem?
2. If not, as seems to be the case, is my system safe and secure? Will I face any issues by ignoring this error?

I recently built a new computer. For CPU, I am using AMD Athlon II X2 @ 2.8GHz... However, when I do cat /proc/cpuinfo, I get the following:
processor : 0
vendor_id : AuthenticAMD
cpu family : 16
model : 6
model name : AMD Athlon(tm) II X2 240 Processor
stepping : 2
cpu MHz : 800.000
cache size : 1024 KB
and same thing for processor: 1 Notice that for cpu MHz, it says 800.000. However, that is not correct... Shouldn't it say 2800? Is this a bug? Am I looking at this wrong?

I've been using Digikam and it's a huge blow to my system memory. Even after quitting I still feel my computer to be slightly slower. I tried running the commands from [URL] but I get this instead
bash: /proc/sys/vm/drop_caches: Permission denied

Here was I get on my screen.
I don't know why this is happened. But before I rebooted, I could not see any content on Windows like update or shut-down (if I tried to install something and it asked for confirmation, that window was blank. Or before I shut down, I had to push enter, since that windows was blank.)
I don't think I installed anything and computer was working just fine before.
I don't want to reinstall everything again.

Trying to change permissions on a file in /proc/sys/fs/inotify. The command syntax are:
Code:
sudo chmod u+w max_user_watches
and the result is:
Code:
chmod: changing permissions of `max_user_watches': Operation not permitted Also tried to change it when logged in as root, same results. Parent directory permissions are dr-xr-xr-x, and are the same up the chain. Tried to change the directory permissions to u+w, that didn't work either. FWIW, /proc is part of the / partition, and it has ~600MB free space.

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.
Default permissions for the file is:
I can change it with:
But that does not stick after a reboot. Is there some configuration file for file-permissions in the /proc directory in Ubuntu Server 9.10? Or do I just have to stick a chmod line in some startup script?

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
Code:
I: Bus=0003 Vendor=15c2 Product=ffdc Version=0000
N: Name="iMON Remote (15c2:ffdc)"
P: Phys=usb-0000:00:12.1-2/input0

Red Hat Enterprise Linux Server release 5.4 (Tikanga) 2.6.18-164.11.1.el5xen (Xen release for virtualisation)
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 just discovered that you can automount an ext4 filesystem with acl enabled by running "tune2fs -o acl". (I knew about tune2fs but did not dare to use it until now). However, the acl mount option does not show up in /etc/mtab and /proc/mounts. Can I ignore this, or is there a way of telling the system about the actual mount options?
Edit: I can do "tune2fs -l <device> | grep acl | awk '{print $4}'" and if that isn't empty I can update /etc/mtab with "mount -f -o remount,acl <device>", but like the udev rule I previously messed with this seems lumberingly unelegant to me.

I want to know what's going on here. I'm used to find files in my Debian box usingfind / -type f -print0 | xargs -0 grep -l "foo"but it's been a while since this type of search simply stops at the /proc/kcore directory. I know it has something to do with memory. Is this normal?

/proc/bus/usb/devices should not be used anymore (and can't be mounted anymore on Ubuntu 11.04) But what is an alternative to it, for use in a terminal? I could easily grep that output to look for a certain device, but I'm lost in all the /sys/ entries...

Is there a simple way to determine the CPU socket from the output of /proc/cpuinfo. Determining the type of processor is simple enough, but the processor I have (Celeron) has two different possible sockets. The output of /proc/cpuinfo is:
processor : 0
vendor_id : GenuineIntel
cpu family : 15
[Code]...
I've looked on the Intel processor finder web site with appropriate filters, but the stepping values do not appear to match anything.

I need to record Tx/Rx bw in my c program at defined intervals. I am aware that there a bunch of available tools but I need a minimal version with only Tx/Rx bw with no other details. I have tried the tool bwm-ng which mostly serves my purpose but either it runs continuously in the console or saves result in html file. It does not have any options to save the result in txt file which could have been easy to parse.
Is there any other simple way to record Tx/Rx bw in a program?(without using tools from /proc/net/ or any) I am using Mandriva Linux 2.6.31.5.

is there a way to make the /proc filesystem writeable? With aufs or unionfs i can't join the /proc filesystem with a writable directory directly. But i think it should work by using one of this file systems.If i try to join two dirs write-proc and virtual-proc Code: mount -v -t aufs -o dirs=/tmp/write-proc/:/tmp/virtual-proc/ none /tmp/joined-proc/ and afterwards make a bind mount /proc to virtual-proc Code: mount --bind /proc /tmp/virtual-proc/ i can't see any change in /tmp/joined-proc.

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?
