[BLUG] Re: BLUG Digest, Vol 13, Issue 1

freeman@freeman-desktop:~$ uptime
19:46:16 up 1 day, 18:57, 2 users, load average: 0.22, 0.25, 0.18

Not that impressive, unless you consider that until last month I was
running Windows. My family made the switch to Ubuntu and love it.

Yeah, I know in the grand scheme of things, I'm just a small fry.

I always heard rumors that it was the BSD folks that managed the truly
huge uptimes.

In Linux it is possible, but you need to be careful that you've compiled
your kernel to only use absolutely the features you need, and then you
need to monitor the kernel security issues. Then once the system has
been up a nice long while you have the added concern that if you do
encounter a security concern that effects you, the rest of the system is
then old enough that you need to either back-port security fixes to the
earlier kernel line, or you need to upgrade the whole OS.

Personally, I wish my uptime was smaller than this. I'm in the process
of migrating all my systems to Ubuntu LTS. I really like the prospect of
knowing exactly when the next release will be available. The short-term
releases can be used as early betas for the next LTS release, so you can
be aware of upcoming major issues with internal software well before
the OS is actually released. (Sometimes when software is being phased
out, or certain libraries are being updated it can cause quite a bit of
concern if you are not prepared.)

Wow, that's only a week away from 3 years. I guess you win. There are
some people online who report uptimes of 4-6 years though.

blacks@bell:~$ uptime
10:33am up 1088 days 12:52, 7 users, load average: 0.22, 0.34, 0.31

This is a Solaris 7 running on end-of-lifed hardware. We fully expect
that if it ever goes down it just won't be coming back up. We're in the
process of migrating from it.

Since that isn't running Linux, I felt obliged to mention the next one.

(omitted):~$ uptime
10:33:50 up 1058 days, 23:35, 1 user, load average: 0.00, 0.00, 0.00

This is a log vault. No ports open outside multiple firewalls. Only
two user accounts. The whole bit.

Steven Black

Re: [BLUG] Uptime wars

I had an HP-UX machine reach ~800 days before. I had to reboot/reload
from tape after it was owned. After that I no longer cared about
uptime.

Re: [BLUG] Uptime wars

I've managed some machines in my day with extremely long
uptimes... not sure if I ever made 700 days, but in that range.

I always had mixed feelings about it, though: don't you worry after a
while about all of the kernel updates that you haven't applied?

[BLUG] Uptime wars

suso@hector ~ $ uptime
02:58:33 up 700 days, 22:53, 1 user, load average: 0.00, 0.00, 0.00

Hector is the router on the old Suso network. So it does do a fair
amount of work. Unfortunately, I'll have to turn it off to move it to
the new network this week.
