I know there is an ongoing philosophical debate about weather it'ts better to leave the ccomputer running or shut it down when not in use. I have not decided for myself, but my Debian desktop system has now been up for a whopping 4 days, 1 hour since my last reboot!!! This is a record for me (was running Win XP before Debian).

Just wondering how long your Debian desktop or servers have been up since your last reboot. (:~$ uptime).

Debian Unstable 92 days 6 hours

Personally I found that trying to set personal uptime records just for the sake of, well, setting a new uptime record ended up costing me $$$$ in unnecessary electricity bills. For me, as long as I am the one who determines when to reboot (as opposed to a system crash forcing me to reboot), the total uptime doesn't matter.

Under Linux (pretty much all distros), my machines just don't need to be rebooted, and unless I am installing new hardware (recently upgraded to nVidia 6600, woot!) there is no actual requirement to reboot. My view is that if I know I'm not going to be using the PC for at least 3 days, aka I'm on vacation, then I power down. Otherwise, I leave it up. Longest my box has gone is about 90 days, but again, the only reason it was stopped was because I was going out of town for a week and didn't want to pay for the electricity to run a machine without using it for the duration -- J.W.

My record was 145 days with my internet server before I had to reboot for hardware maintenance. I agree with JW though as regards costs. If you are not running an internet server it's a waste of money having it running doing nothing. Modern boxes use quite a lot of power and therefore do cost money to run.

[rbochan@halb ~]$ uptime

The only reason it's not longer is because, 96 days ago, the main breaker for the house blew.

I had my system up for about 60 days (Debian Testing). I installed a new kernel on it, so I had to reboot to load the kernel.

Current uptime is 17 days.

I know it's not debian, but I had a modified Slackware 7 with a custom kernel on a 486 on a dedicated UPS. Ran it as a little web server, worked real nice. Uptime was somewhere in the neighborhood of ~240 days, I remember it only went out because the power went off for like two days.... then it wouldn't start back up when the power came back on... turns out the hard drive died, hah. Not sure if that was because of the power failure, or the extended uptime, but I had to get a new drive for it. Current uptime on my Gentoo desktop is 16 days, 2 hours, and 13 minutes.

78 days for Debian stable until a friend of mine caused a short circuit...but I guess it could easily run for years if there is no power or hardware failure.

I usually power down my machines when I am done using them for the day. One concern about leaving a machine up all the time is that the hard disk, if you have one, has a limited lifetime before it will crash. On the other hand, powering up and down sends voltage pulses through system, which can cause weak chips to fail. And then there may be concern about the stability of your electrical power service as well as severe weather. I always power down when there is a thunder storm within audible range. (I have power-strip surge protectors but no uninterruptible power supply).

[root@topaz ppd]# uptime
14:05:15 up 1 day, 1:26, 4 users, load average: 0.00, 0.00, 0.00


1 day... yeah!!

My Debian server (uptime max ~120 days) did (because of maintenance) not exceed the 260 days of my old Red Hat server (~260 days..), the later was much simpler... in those days... (RH6 in the end 90-ies)

Hate to say this I am sure it would run a long time. but I only use it when the project calls for it. So it is usually a day at the most .
Sorry.
