General :: Calculation Of Working Time Based On System Uptime

Jul 28, 2010

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)."

General :: Uptime - Getting Date & Time Of System Startup?

Mar 28, 2011

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.

General :: Difference Between System Uptime And Last Boot Time?

May 11, 2011

My Linux system was last rebooted few hours ago. But it seems little confusing for me to figure out the exact reason behind it. I guess following command should justify what i meant to say.

# date
Wed May 11 13:22:49 IST 2011
# last | grep "May 10"
reboot system boot 2.6.18-194.el5 Tue May 10 17:35 (19:46)
root pts/1 XXXX Tue May 10 17:24 - 18:18 (00:53)


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.

General :: User Add With UID Calculation?

Aug 27, 2010

I am having problems with the useradd command. When I call "useradd someuser" the program starts and never finish. When I give the UID option (useradd -u ) sometimes it works properly, but with some UID's that aren't in /etc/passwd it shows a message saying that the uid is not unique. I checked out /var/log/auth.log and nothing about the command is being logged. It seems that the command is not calculating the new UID prperly.It's running on a Debian Linux 2.6.26-2-686 i686 GNU/Linux

General :: Backup A Debian Based System?

Oct 8, 2009

Issue: I want to backup my system and be able to restore if/when my system crashes.

Setup: Thinkpad T61 running Sidux KDE3.

I want to back up the system files more than personal data. What I have found is that when I apt-get dist-upgrade the upgrade performs without error, but when I restart and login I get a black screen with a mouse. From the 'black screen' I can open yakuake with F12 and then launch applications and such from the command line. The point of this more troubleshooting right now. Later is so I won't need to do a complete reinstall.

What backup prog have you used that will backup the complete system and is easy to restore?

Debian :: Bash Script Based On Time Of Day

Mar 25, 2016

I'm trying to get a bash script to do different things based on the time of day, but at least once a day the test fails:

Code: Select allNOW=$(date +%k%M)
if [[ "$NOW" -ge 1000 ]] && [[ "$NOW" -le 2200 ]];then
        alarm lon
        alarm loff

This is the error, and line 59 is the second quoted above:

Code: Select all/home/electrolux/bin/ line 59: [[: 059: value too great for base (error token is "059")

The script is run every minute, and this error only occurs at 12:59AM, or 00:59.

I presume the problem is either $NOW is being set to 059, or the testing is seeing 0059 as 059. I think the latter, because for the rest of midnight 'til 00:58 the script works. And with some Googling it seems that the leading 0 is making test treat the number as octal... is there a way to tell it it is decimal?

Perhaps this is just some poor time-testing code? Looking at it I don't think it will cope with set time period that crosses midnight..... there's probably just a command to do what I want, isn't there? I know I could have two different scripts cron'd for the different time periods, but it would be much more preferable to be just the one.

General :: Debian Based - Arch Based - What Is The Practical Difference?

Is a distro based on Debian say, easier for a newbie to learn or work with than say one that is FreeBSD based?

Security :: IPTABLES - Restrict Internet Access Based On Time Of Day And MAC Address

Feb 6, 2010

I am trying to configure my Linux router to restrict Internet access for one computer on my LAN. It needs to be restrictive based on the time of day and the days of the week. I am using the MAC address of the computer to single out the one computer that needs to be blocked. However, this is my first attempt at making any rules with iptables, and I am not sure if I am doing this right. If some one can take a look at this I would greatly appreciate it. This is what I have done so far.

Here is my thinking. Create a new target. Check the MAC address, if it is NOT the offending computer return to the default chain. If it is the offending computer check that we are between the allowed hours and dates and ACCEPT. If we are not within the time/date range then drop the packet.


Here I am trying to route all packets regardless of the computer on the LAN into the blocked_access chain for checking.


Is it a good idea to route all traffic through the blocked_access chain? I do run other servers that are accessible from the Internet, so I am not sure how this setup will affect that. I also use shorewall on the router to setup iptables for me. How would I integrate this with shorewall?

I am using squid to block access when he is using the web browser. However, he is still able to play games(World of Warcraft) and the like.

I am using Debian sid, iptable(1.4.6), shorewall(4.4.6), kernel 2.6.32-trunk-686.

General :: How To Set System Time In 12/24 Hr

Sep 19, 2010

When I use the `date' command on RHEL5, I can get the time shown in 24 hr format. I wonder if the time can be shown in 12 hr format. But I don't want to use the `date +FORMAT' to do that, neither `alias date='date +FORMAT''. I just want a simple `date' to show time in 12hr format.Is there any configuration file about the 12/24 hr format? Is the format related to the value of the environment variable 'TIMEFORMAT'? I can't find its default value by 'set | grep -i timeformat'.How can I know what the current format is? I mean, when I use `date', I can get "Sun Sep 19 13:22:50 CST 2010", which seems like 24hr format; but when I use `hwclock', I can get "Sun 19 Sep 2010 01:23:05 PM CST -0.174299 seconds", which seems like 12hr format.
