I want to know if there is a way to know the uptime for a server after a reboot process, I need that information for a statistic, but I forgot to take the uptime before reboot the server, so I am looking for that information after the server is power on.

How can init process uptime be longer than the uptime of whole system?
Code:
martin@server:~> ps -p 1 -o pid,cmd,bsdtime,start
PID CMD TIME STARTED
1 init [3] 20:50 Mar 05
martin@server:~> uptime
2:23pm up 559 days 1:42, 10 users, load average: 0.18, 0.28, 0.34
martin@server:~>
I know that uptime prints the time a machine has been up and running, but is there an easier (reliable) way to get the date of the start up than counting down from this output?I tried looking around /proc, but didn't find anything of relevance. There's also a line like this on my dmesg: [ 0.673492] rtc_cmos rtc_cmos: setting system clock to 2011-03-14 14:26:52 UTC (1300112812), but I'm wondering if this method is distribution and kernel version agnostic.

My question is Why the uptime is saying that the system is up since last 47 min.It should be more than 1 day if i m not wrong.
I know several tools that allow tracking time spend on different tasks / projects.Is there any existing tool for very very simplified work-time-tracking.I am an employee, come to the office, switch on my laptop directly. I have mostly around 1 hr lunchtime, but sometimes less, sometimes more.At around 18:00 I want to type one command in the console (or simple GUI would also be okay of course) that tells me:"1 hour overworked. Go home now! (came at 8:00, 1 hour standard lunch-break)."

There is an existing thread that contains a very similar question to mine, but since the existing thread is approx. 7 years old, I thought I would go ahead and post my question.I am wondering how I can change "uptime" on a Linux 2.6 box. I want to do this to test a complex wireless system that contains multiple Linux boxes.I am able to change "uptime" on a Solaris or VxWorks box with "lbolt" and "tickSet" commands respectively. But these commands do not work on Linux boxes (no surprise there).
View 9 Replies View RelatedI've read from some Web-page that GNU/Linux resets it's uptime every 497 (498) days... So even if GNU system works 1000 days, uptime never will be more then 497 (498) days. Is it true?
View 2 Replies View RelatedThis seems like a nicely populated forum so I hope some knowledgeable people happen to see this thread.
I've been encountering this issue where the system will not respond to seemingly anything after being on for generally no shorter than a day but sometimes as long as three days. This has been going on for few months since I only have physical access to the machine for about a day or two once every two weeks. So I'll come to the machine, reboot it, it will be fine for a day; then about a day after I'm away from it, it will not respond in any way. When I am away from it I only have ssh access, but when I'm with it, I have access to anything and everything.
After it locks up into the silent issue I have tried: ssh either remotely or locally, where it will time outPinging from the local network, where I get "ping: sendto: Host is down" a lot and occasionally a "ping: sendto: Host is down"Plugging in a monitor and keyboard, where the monitor never gets a signal no matter what I do on the keyboard. When it isn't locked up into the silent issue and I plug in the keyboard and monitor, the monitor gets a signal right after I hit the spacebar for sure. After the silent issue triggers it's fans still whir, the power light is on and light on the Ethernet port is on (and turns off if I unplug the Ethernet cable, and back on if I plug it back in) like everything was normal but there is no hard drive or network activity (even after unplugging/replugging the Ethernet cable).
After a reboot, all log files have nothing past a certain time and date, which I assume is the time when the silent issue got triggered. My setup is the following: Debian 5.0 "lenny" on an HP ProLiant ML110 G6Using full disk encryption with ext3 which was all set up by the installerIIRC "core" and "minimal" were selected in tasksel during install. I'm sure about "core", not about "minimal". The programs I have running are apticron, ddclient, sshd, fail2ban, screen, php-cgi (php5-cgi), cherokee (from unstable) and rtorrent (from unstable). I can provide a "ps aux" if necessary. The packages from unstable, that I have all set to Pin-Priority 990 in /etc/apt/preferences, are:

I'm pretty sure I don't have ECC memory so I don't think a lockup from a flipped bit is an issue. I'm thinking one thing to test would be to set up some kind of daemon that sends log info over the network to a logging server and compare the latest timestamps of what the daemon sent versus what the latest info on the disk is, and that would show that the issue is with the encrypted disk since things are still functioning in memory but not able to write to disk. If that's the case then I guess it locks up eventually from not being able to read or write something. Does anyone know of something out there like this? Or perhaps a way to do something similar?
Is there something I could do to determine whether this is caused by maybe some kind of kernel panic or by something like the motherboard having issues?
trying to write a script to gather the uptime of a box and send an email out if the box has died. Problem being that this is hard when `uptime` changed from the format 23:59 to 1 day. Is there a method to just see the uptime in hours or minutes or even seconds?

View 10 Replies View RelatedI've installed Ubuntu server on a small box with a couple of large hard drives to use as a remote backup server. Since my backups will run nightly in the wee hours, I'm configuring this to use Wake-on-LAN to start the server and run the backup. Once the backup completes - probably on the order of an hour later - another script shuts the server down. Once in a while I'll remote in to update packages and check on the status of the system, though I can check backup logs to insure that is still running.
Need I be concerned about the various cron jobs that periodically run to tidy things up? Should I periodically - say once/month - leave the system up for a full day to make sure that everything that needs to happen will run?

View 2 Replies View RelatedIt is the strangest thing. I can not receive emails on this server after it has been up for an hour. I noticed that everytime and email is received that a sshd opens but never closes. Causeing a memory issue that I dont know how to fix. Also the mailq grows and grows. Mostly with email stating the recipient and send are both [URL].. also postmaster@mail.jmchd.com shows mail system configuration error. I have to restart the server every 30 minutes so users can get and send emails. This is horrible because for every 5 minutes out of the hour emails are bouncing.i have looked through them but I know not what I am looking at.
PS. I was thrown into the position and have limited knowledge. I am used to a GUI.
I need applet which shows the total data usage (In+out) (of the current session or since the uptime) on the panel.I searched a lot, but everytime I had to click somewhere to see my data usage. I don't want that. I want my data usage displayed regularly on the panel.
View 9 Replies View RelatedFurther to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

View 2 Replies View RelatedI have installed CrunchBang, then I moved the /tmp and /var to different partitions (I like to put these on reiserfs) the reason I did it after the install is because CrunchBang's installer doesn't give me the options to create reiserfs partitions during install (but does recognise reiserfs as I can manually mount them). Also these two partitions are logical.Anyway I have Windows 7 and Ubuntu 10.04 already installed and working fine but CrunchBang always changes the UUIDs of /var and /tmp when I reboot. Is that even possible I have also tried using the old method of /dev/sd** but of course that gets changed as well.

View 1 Replies View RelatedRunning close to a go live date of 11/10/10 and need to have this fixed. DBA is pointing to the OS which is RedHat Enterprise Release 5.3. with Oracle RAC 10G
Oracle works fine it just won�t start up automatically after a reboot. After a reboot a person with root access has to increase the number of semaphores and then oracle will start and function. The next time the machine is bounced the same issue will arise and the semaphores need to be increased again by hand. Every time the machine is bounces the semaphores need to be increased by hand. This is not normal for a Unix machine. Semaphores are not part of the oracle install, it is a kernel parameter on Unix machines. Eventually after several reboots the semaphore parameter will be too high for the box to function. Once the semaphores have hit their peak, we reset them back to the original value and the whole process starts over again. This is a Unix build issue that has only surfaced on the production machines. The DAS development machines have the exact same oracle build and do not have this issue.
