I was wondering how to allow someone to use a user account for two hours a day. After this time, it will log them out, and not allow them to sign back in until the next day. How can I do this?
View 2 RepliesPossible Duplicate: time tracking application on linux Every Linux time-tracking application I've seen assumes you're tracking time for projects, perhaps to create invoices later for your clients. This is not what I'm looking for. Rather, I just want some insight into how I spend my time on my computer. I'd like to waste less time on my computer, and spend my time on more productive tasks. The first step to improving anything is to measure it. But I can't be bothered or remember to click on some icon and switch "projects" every time I change from my terminal to browsing ....., or something like that. I want the time I spend on different applications tracked automatically.

1. i want to limit the bandwidth to 400k/s per connection.
2. i also want to limit the max connection per user a/c
i have some thoughts on the 2nd requirement. in the user configuration file of /etc/ppp/chap-secret, you can specify the range of ip the user can get, does it limit the max connection per user a/c? or they can connect anyway, just every now and then a box pop up says conflict in IP address?
I would like to be able to schedule a limit for an IP connection for my kid's computers/iPods. Since I know the MAC addresses of their various hardware items, is there a way to shut down their connectivity at a particular time via the DHCP server or perhaps a firewall rule?

I notice that when someone sends a message from my Postfix server & it can't find the destination server or if there is a incorrect domain recipient entered by mistake, it sits in my Postfix queue for days. I think perhaps 4-5 days for some reason. I was wondering if I could shorten the time so the sender gets a delivery failure message kicked back to them in 24 hours rather than waiting 4 or so days.

View 5 Replies View RelatedI've noticed that "su" can be run from any user account so long as the user knows the root password.What if I want to limit the ability to "su" to only 1 user account? For example: Pretend my desktop has 4 different user accounts. Currently each user account could run "su" for root access if the person sitting in front of the screen knows the password.
1) Could I somehow make only 1 of the 4 user accounts able to "su" into root mode?
2) If yes, then would doing so have any side-effects?
Linux bash inline command to execute a program and limit the resource.As I know, to limit the resource I can use ulimit command.But, the problem is when I set the CPU time limit 1 second, and then I want to execute another program with CPU limit 2s, the ulimit command return an error like this: bash: ulimit: CPU time: cannot modify limit: Operation not permitted and absolutely my program killed in 1 second.So, How can I make the second program running with the CPU time limit 2 seconds?
View 3 Replies View RelatedI was struggling how to phrase the question (in the subject) so let me clarify... I wish to install Windows 2000 and then do Ubuntu, on the same PC. I never had a dual boot before but I understand that it goes automatically (after a short time) to default Windows if Ubuntu is not chosen (on the boot up screen), correct? If so, if there's a "countdown" of sorts, is there a way to disable it? I wish to have control over that aspect, have unlimited time during that boot "choose one" screen.

I tried linking my MSN account to Empathy Messenger for the first time - all went well But.I went to my friends house the next day and he told me that my MSN account status on his Windows PC MSN was continuously logging in and out. My computer had been switched off all morning and only used the night before. I went home logged on to Ubuntu 10.10 Empathy and I was logged off - I logged on and then logged off and rang my friend he told me that My status was now showing "That I was away"
I have dual boot system (xp) I went and changed my MSN password and question- should I be concerned is this a known software glitch/ security issue?
I use vsftpd. I would like to know if there is a way to limit the upload speed. Only the upload speed so the "anon_max_rate" and "local_max_rate" don't do the job. Someone told me about the trickle but I expected a more recent application.

I was unable to boot my computer because bad blocks in my drive 'appeared' over my current and most used partition, for 9.10. I discovered there were 101 bad blocks on the drive, so I called western digital and had them send me a new one. In the meantime, running fsck on the drive managed to sort out the bad blocks for the time being. The replacement drive arrived on Friday, and since then, I've been trying to clone my current drive to the replacement. Using Clonezilla, I kept getting the error "bad partition table on /dev/sdb". Alright, I tried a bit-by-bit transfer using dd, but for some reason, the transfer fails on the last partition, leaving the replacement drive unbootable. What do you think I should do? Does it sound likethet sent me another faulty drive, or am I just doing something stupid? I've copied my drive before, but ive never had these problems- i just popped in Clonezilla and away it went.
I'm really leary about this drive, I have many important files for school and TONS of music. The school files, I can back up, and the music could be shuffled to another external drive, but I reallydo no want to go through all of the time and effort to move it to a new drive that may already be failing. Does anyone know what I should do? Is there some way to test the 'health' of the drive before I spend hours rebuilding my filesystem?

I have a VPS server with 512 MB memory. The php.ini is set so script memory limit = 16 MB. However, I have noticed in my top report, instances like the following:
Quote:
5484 coldclim 25 0 46476 32m 5920 R 0.0 6.4 0:00.93 php
The bold number of 6.4 is the % of sever memory this process is using. 6.4 % of 512 MB of memory is about 32 MB of memory, so it appears that this isn't being limited by php.ini. Am I correct? This leads to the next question: Is there some way to limit the amount of memory a single suphp process can use? (Basically, something like the setting in php.ini which limits suphp processes in the same way.)
anyone knowledgeable could follow this thread? [URL]
View 1 Replies View RelatedI've been running arch linux, with my clock set to UTC with no problem. Recently I installed slackware on a different partition. During the setup I chose to set my clock to 'local time' instead of UTC by accident. Now in slackware my clock shows the wrong time. Also in arch it shows the same wrong time.
I booted back into slackware and ran pkgtool to enter the setup again, and changed my time to UTC. But this makes no difference. My clock is still wrong in both slackware and arch. Do I need to reboot after changing my clock settings in slackware before it takes effect? how the clock or the setup works.
I am an experienced Linux user, but have never used Salix before. I have a root account set up on my other Linux distros, but can not figure it out using Salix. The reason I want a root account in Salix because I believe in freedom of choice, and my choice always was and always will be to have a root account set up so I can login as root. I am aware of the risk involed in creating a root account.

But it seems that all my outgoing mail is only sent via one account (say first@gmail.com) even if I select another account for the outgoing I.D field and FROM field. When I look in the sent folder the headers shows the correct sent from account but my recipients headers show they were all sent from first@gmail.com! Ebay keeps bouncing my emails back too as a result saying the email is not registered. It used to work just fine so not sure what is happening.
