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 4 RepliesI need to write a GUI for the web to gather the following info:
Username
Password
SomePlainText
Path1
PathN
Of course, I then need an 'submit' button. I then want to have the user upload all paths supplied from their machine to my server. I hope to work with this data as arguments for a bash script. Also, I need to work with all possible client OSes consistently. What language should be used?

Is there a way in Gnome to gather all windows to one screen? I switch between two screens and one from time to time, and if I don't remember to move all my windows onto my laptop's screen (only) it is a nuisance to reckon out.
My use model is that I have a laptop with a monitor hooked up to it. I take my laptop to code reviews and therefore need to condense to once screen. It would be nice if there was a command to invoke that would gather (tile, perhaps?) all windows on one screen so I wouldn't have any off-screen windows when I "go mobile".

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.
View 1 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?
I'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?

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?

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 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)."
