General :: How Long Was Keyboard Idle?
Nov 7, 2010
Suppose I am almost sure that from last Thursday, 3.00pm up to the same day at 10.00pm I was away from the machine, but not absolutely sure. Linux probably knows better than me. Maybe there will be a text file from which I could infer the keyboard was idle from Thu 2.40pm up to 11.10 pm. In this case, I would reach absolute certainty. But where could such file be in the /. tree or what could its name be (for in the latter case an updatedb followed by locate would do)?

My hard drive all of a sudden starts to read and write all on its own for around 15 seconds at a time while at idle or while I am just browsing the net. At first I thought it was from cron running but I have that disabled.

When I run top d 0.5 on my machine and I press 1 to enable the SMP View, I notice that all of the CPUs keep toggling between 100%idle and 0% idle.
The odd part is that when a CPU goes to 0.0% idle, I would expect to see one or more of the other columns peek, but they are not.
What is causing this?

how to log out an idle session. I was using putty to connect to a Debian machine to edit my .profile file. I got disconnected. Ideally I would want to log back into my own session. If anyone can let me know how to do it, please? If not I want to open a new session and then log off my first session (see below pts/0).

I have a PC which I built ~3 years ago which had been running smoothly and silently until recently. Now, the CPU fan likes to spin up to 1200-1500 RPM even when it's idle, which is rather annoying. I have not made any recent changes (software-wise or hardware-wise) to it.
The specs:
Motherboard: Gigabyte MA78GM-S2HP
CPU: AMD Athlon(tm) Dual Core Processor 4850e
Case: Antec Minuet 350 MicroATX
OS: Ubuntu 10.04, Linux 2.6.38-10-generic
I installed the lm-sensors and hddtemp packages (via apt-get) and configured them. Here's a typical output at steady-state, where the computer's been idle for a while and the fans have been spinning for the same while:
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +29.0°C
Core0 Temp: +32.0°C
Core1 Temp: +27.0°C
Core1 Temp: +22.0°C
it8718-isa-0228
Adapter: ISA adapter .....
$ sudo hddtemp /dev/sda
/dev/sda: WDC WD5000AACS-00ZUB0: 35°C
These all seem fairly normal to me, so I'm perplexed as to why the fan continues to run at such a high RPM. What does the ALARM that's reported for in6 mean? Is it important? I've been playing around with the fancontrol daemon, trying to see if I could get better results than with the default fan management. Using the pwmconfig utility, I generated the following /etc/fancontrol file:
# Configuration file generated by pwmconfig, changes will be lost
INTERVAL=10
DEVPATH=hwmon0=devices/pci0000:00/0000:00:18.3 hwmon1=devices/platform/it87.552
DEVNAME=hwmon0=k8temp hwmon1=it8718
FCTEMPS= hwmon1/device/pwm1=hwmon0/device/temp1_input
FCFANS= hwmon1/device/pwm1=hwmon1/device/fan1_input
MINTEMP= hwmon1/device/pwm1=35
MAXTEMP= hwmon1/device/pwm1=60
MINSTART= hwmon1/device/pwm1=180
MINSTOP= hwmon1/device/pwm1=100
This only sort of works—as soon as I enable the fancontrol daemon, the fan shuts off at first (good), but the temperatures of the 7 different sensors slowly rise, even when everything is idle. Eventually, when the Core0 Temp sensors goes past 35°, the fan comes back on, and then it alternates from being on and off at around 500-700 RPM, as the temperature goes back and forth across the boundary. It's certainly much more pleasant than 1200-1500 RPM, but it's still far from desirable.
Here's an example of the sensors output in that situation:
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +36.0°C
Core0 Temp: +38.0°C
Core1 Temp: +34.0°C
Core1 Temp: +30.0°C
it8718-isa-0228
Adapter: ISA adapter .....
cpu0_vid: +1.100 V
I opened up the case, and the CPU heat sink felt warm but not excessively hot. I tried taking off the heat sink, cleaning off the thermal paste, putting on new thermal paste, and putting the heat sink back on, but that didn't seem to have much of an effect, if any. The two other heat sinks—one on the built-in AMD 780G graphics chipset and the other on the AMD SB700 southbridge—felt noticeably hotter than the CPU heat sink. So, my question is this: What should I do to get this computer back to the state where the fan is off when it's idle? Can I solve this with a smarter fancontrol configuration?
I cleaned out the heat sink and fan as best I could with compressed air (there wasn't a whole lot of dust, but I got rid of what I could), but still no dice. Rebooting into the BIOS configuration gives me the same results—the fan still runs at 1100-1200 RPM, and the system and CPU temperatures are reported as 40-44°C. Should I add another fan? The integrated GPU and the SB heatsinks felt significantly warmer to the tough than the CPU heatsink. The BIOS reports a system fan speed and NB fan speed of 0 rpm (since I don't have more than one fan).

All the kill idle user processes scripts I've seen don't take into account that the user might have multiple sessions open. Such is the case with one of our clients. Currently, every hour or two I need to do the following:
This will get the TTY and idle time for all users.
For each idle time over a half hour, I do the following (TTY is the TTY from the previous command with a space.
I then kill those processes.
There must be a way to do this automatically in a bash or perl script. I've tried both, but can't seem to get things to work properly.

I'm trying to understand if anyone is left on a server. Basically I manage a simple linux server remotely used by 3-4 individuals. I can never tell if someone is actually on or not using w/who.What I'm seeing is some people having what appears to be inactive/lost VNC sessions. I don't understand idle fully, but I do believe a program (without user interaction) can clear idle back to 0, correct?Anyway, I'm asking because every now and then I need to reboot the server, and I do not want to interrupt any program working on calculations or waiting on having the data saved.
Code:

I was running grsync (rsync gui) to do a backup of my root and home partitions to a local external hdd. Home is currently 21.2 gb and root is about 60 gb, but the backup ran for nearly 24 hours before I canceled it, without finishing. How long should an 80ish gb backup take to do?
I made sure to disconnect other externals so they wouldn't be backed up as well. It was just my root and home being backed up.

I am running Centos 5.3. I ran no updates, performed no installs, nor changed any configuration immediately prior to this issue. My problem is this: when I run the command startx (default runlevel 3), it is a long time (5-10 minutes) before Gnome startx, and once it does start applications will not run. Also, when I try to use sudo (from any environment, even ssh), it is a long time (5-10) before the command is executed.
I cannot say for sure, but it seems like this is an intermittent problem. Sometimes X takes a long time to start, but once it starts it will launch programs. Sometimes X takes a long time to launch, but once it starts it will only launch certain programs. Though presently X always takes a long time to start, and I cannot successfully launch any programs.
A while back a had a similar problem to this (x taking long time to start, sudo taking long time to execute) and it ended up being a DNS problem. Unfortunately, I cannot remember exactly what it was and I stupidly did not document it. Maybe this is also DNS related, I don't know.
I don't know what log files to look at for problems with X, Gnome, and sudo taking a long time to start.

I managed to, in a bit of a "Oh shit, I'll lose my data" panic, be stupid enough to xkill the Ubuntu 10.04 installer while it was making an ext3 file system on my external hard drive. This drive was equipped with ext2, I had not set it to format (at least not consiously), and it had a LOT of data on it. Only half an hour after killing it I realized it might simply have been converting rather than formatting.
Anyway. Because this was my own fault I started searching for possible solutions. I tried e2fsck, ran testdisk and gpart, as well as several data recovery programs both from Windows and Linux. All I have been able to get back with that is a whole bunch of corrupted files and some music.
Now I have unleashed e2salvage on the beast, which so far has been looking promising, other than some "directory inside Inode table" errors. It found almost 20000 directories, and 174 directory beginnings.

I have two minor problems with Ubuntu which I've been running on my aging Fujitsu-Siemens Lifebook for a couple of years now.
First, I recently upgraded to v10.04 with no problems. However, I've just applied the latest updates via Update Manager and the laptop will now hang after the welcome screen.
There are no error messages, just a black screen and the case fan runs a full tilt until I force a shutdown. I've waited 5 or so minutes to see if it's actually doing anything but it would appear that it isn't.
The only way to boot the laptop is to choose an older Grub menu option, then it boots up fine. It may very well be a hardware issue because another (newer) laptop in the household has updated no problem.
Next, I tried to change the password of the admin account using "Users and Groups". It appeared to work but then I had to use the old password to log in again. On logging in I am prompted for the new password, the error message saying that the "token ring" password (I think it's token ring, I'm doing this from memory) doesn't match.
Again I can live with this quirk but it would be nice to put it right.

I'm having trouble with Vim in any terminal emulator I use. I have a link (vi) to vim. Occasionally it will take very long to load, whether I use 'vi' or 'vi file'. Before, if I could I would restart X, and then it would load instantly again, but I waited this time and it did load, after a minute or so. Is this a problem with X or vim?

I am changing the password of a truecrypt file container. This takes around 1 minute. Why?
time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null"
If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password:
open("/dev/urandom", O_RDONLY) = 6
read(6, "36&{35121221234320234313242312I326235245224300354O)270Q200 201J227224311_212367"..., 640) = 640
close(6) = 0

I'm a Windows admin who does part time Linux server installs. Most of the time I'm asked to deploy a generic Windows server, install a few basic applications and if needed some other applications like Nagios or Zabbix. My question is for long term support, or patching should I be focusing on deploying with repositories to install applications or compile from source? In the Windows world you can patch and update from Windows Update, but is there problems using 3rd party repositories for future updates? Would one of these locations go off line?
