I have just created a periodic maintenance schedule for friends using Windows XP, covering tasks needing to be done weekly, monthly, semi-annually and annually. That set me to wondering what maintenance my Kubuntu system needs. What periodic maintenance do you do?
View 1 RepliesI keep noticing disk activity every roughly 1 to 3 seconds even though there is "nothing" going on. Of course, I run a number of "system" and "user" application packages - Apache2, MySQL, Browsers (Opera, IceWeasel), an SMB client and server, OpenOffice 3.0RC8 being the most prominent ones. I wonder what might be the cause for this constant disk activity which happens even when none of the applications do any noticeable work at all. Is there a way to determine the process that does those disk read/writes?

Is there a way to change this, perhaps remounting as writable?
An example of this being a problem is that I was unable to open vi because there were too many session files....
Not to mention it would be nice to actually fix problems....
What are you meant to be able to do if you can't make any changes to the filesystem? What kind of maintenance can be expected?

I have been running Ubuntu as my sole OS for about a month now, and aside from Computer Janitor, I have found no drive/fs cleaning tools, or defragging tools. I know this isn't Windoze, but surely there must be a way of maintaining your hard disk. I mean installs/uninstalls must leave detritus, and file moving must cause SOME fragmentation. Are there any apps, systems or methods in place that provide this functionality?

I am trying to make a periodic boundary condition type function, using an existing class given to me in lecture notes, but am having some trouble! Effectively, I am trying to make an array such that, for a point in any row of a 2D matrix ("Matrix(i,j)"), the command "next_i[i]" will return "(i+1)%L", where L is the number of data points in the row. This will enable me to select a point to the right of any point in the matrix: "Matrix(next[i],j)"

A few weeks ago, I upgraded one of our machines to the 64-bit server edition of 10.04. All went reasonably well (after some hoops to get it to properly recognize/mount the RAID + LVM partitions), but one of the things that confounded the installation process was login timeouts. From doing some research, I thought I'd gotten it solved by removing the checks for updated packages on login, but I either didn't get it done, or there's something else going on here.The issue is that the machine is headless and is actually a file & application server, but I do need to connect to it via ssh on a regular basis. However, the issue isn't related to SSH, as it also happens when I try and log in through the physical console too.
What happens is that every so often, login attempts will time out for a period of minutes, then they will suddenly start working again, instantly giving me my expected shell. Again, I suspect it is something with the way the motd junk is being generated, but having a server that prevents you from logging in is totally unacceptable. I've no idea how to go about debugging what happens because I don't see anything useful in any of the logs, and I don't have a way to trace the login process from outside. I'd love to hear what the problem actually is and how to prevent this from happening.
I recently upgraded my desktop to 11.4 and kde 4.6.1 My desktop has : VGA compatible controller: ATI Technologies Inc RS690 [Radeon X1200 Series] This is legacy ATI stuff, radeon driver loaded (as was in 11.3) and seems to be operating. I am getting a somewhat periodic (5 secs or so) flicker on the display, fast enough to be annoying but not fast enough to really affect anything.
I have seen several threads about short freezes, but realize that flicker and freeze might be a matter of speed and memory, etc. I tried suspending Desktop Effects, that may have reduced the frequency of the flicker but did not eliminate.
I want to write a function that shall execute periodic. means if i set time 1 sec that function should execute in each 1 sec. let us call that function func1. But i dnt want to wait inside the func1 for that 1 sec. Meanwhile i want to run another function say func2 in background . some thing like less priority function. Whnever the time come to execute the periodic function func1 it has to go to func1 and then again in the waiting time , the second function func2 will resume. I wanted to know how to do it.. Can somebody tell me is it possible using signal in linux.
View 6 Replies View RelatedFor months I've been experiencing periodic screen freezes in Debian Jessie. I've tried many ways to debug/fix it without any luck...

My screen freezes periodically.
By freeze, I mean that the mouse can still move, but everything else behind it is frozen entirelyI can switch to a terminal with CTRL+ALT+F1, it's ... I guess... X or gnome-shell or something that's frozen? Not the whole OS thoughThese freezes last anywhere between 5 or 10 seconds and 3-5 minutesI can't predict when they will occur, but often, after a suspend/resume, they will start occuring much more frequently. Also, they often happen after I enter my password and press ENTER on the lock screen after a resume from suspend. But not exclusively -- they can happen at any other time when I'm doing pretty much anything in GNOME...
Things I've Tried...
When frozen, I've tried to CTRL+ALT+F1, login, and run gnome-shell --replace... [*[When frozen, I can successfully CTRL+ALT+F1 and run `service gdm restart`... with the obvious downside of losing everything I have open. But the screen responds immediately and I can log back in to GNOMEI tried running `Xorg -configure` to generate an /etc/X11/xorg.conf file to edit, but received an error about not being able to generate configuration for multiple screens or something (I can retry and provide the exact error if this is a useful direction to try) is it the gnome-shell freezing? Is it X? Is it a problem with the X driver I'm using?
From version 11.3 to 11.4 now often occurs after a problem has already become annoying! My computer connects to internet through a router and sometimes after about 4, 5 hours going through the browser so I cannot reach Google or someone else's server Skype only stays connected!
This is not a hardware problem occurs because even after changing the router and the computer problem remains! When this happens the router has access to the Internet and other computer via wifi can connect without a problem! How to figure out where the problem comes? I attach the output of dmesg:
Code:

I checked this code in google and found that a similar prolem had people from the version 10.3 but I do not remember then I had this problem occur examples of 11.3.
I have tripwire 2.4.1.2 running on one of our servers on a daily basis, and I was curious to know if it is good practice to periodically update the policy file. The reason for my asking that is while the daily reports that I get indicate there have been changes to files on a daily basis, there are also files that have not been modified for over a month. My thinking is an update of the policy file will establish an updated baseline, and those files that have not been changed for so long will not be reported on until they get changed again.

View 2 Replies View RelatedI've been having this one annoying problem that's been plaguing me ever since I installed 9.10 - every now and then Ubuntu will fail to boot or load and throw at me this fantastic message:
Quote:
Mount of filesystem failed.
A maintenance shell will now be started.
CONTROL-D will terminate this shell and re-try.

A couple months ago when this first occurred I researched the issue and discovered that by booting into the live cd and using the following fsck command I could temporarily correct the problem and be able to boot into Ubuntu fine for some time:
Code:
ubuntu@ubuntu:~$ sudo fsck /dev/sda1
fsck from util-linux-ng 2.16
e2fsck 1.41.9 (22-Aug-2009)
[code]....
With this done, I would be able to load and login to my session as if nothing was wrong. Unfortunately, after a seemingly random/spontaneous number of logins/boots later, I'd get the same mount of filesystem failed error once again and would be forced to used the live cd and the fsck command, again. By the way, is that statement about the "superblock mount time is in the future" telling me what my overall issue is that must be fixed?
I'm now tired of this silly routine and would like to figure out what's wrong and put an end to it once and for all. A week ago I reinstalled my system with the latest stable version of Ubuntu 9.10 thinking this would fix the issue, but it didn't - I've had to use fsck from the live cd now 2 times since then in order to access my data and boot correctly. When I reinstalled Ubuntu I told the live cd installer to completely format and use my entire disk for the new OS, but even wiping the thing clean and installing from scratch didn't seem to solve my problem. There are 2 things that I think may be connected to this issue:
1) For some reason when I boot and login gnome-panel will fail to load correctly and be frozen until I use the following to reset the thing:
Code:
killall gnome-panel
This as well happens randomly it seems and occurs irregularly. It's just that I think whatever data is corrupted or whatever might be connected to these improper loads of gnome-panel.
2) Could the fact that I started using the new feature 9.10 offers, the one that allows you to encrypt your home folder, be an issue? I haven't tried reinstalling the system without choosing that option, but could this be a source of my problems?

View 6 Replies View RelatedI decided to create a file server for my family. I have set up a RAID 6 (4 disk) array. My thoughts were to back up the array to a hard drive monthly. Store the drive in a WiebeTech Drivebox, off site, in a "fire proof" box. (The kind for papers sold at Staples or Office Depot. After a year, I would have 12 back-ups. I would then overwrite the previous hard drive. (i.e. HDD from March 2011 would be overwritten on March 2012.)
Additionally, I was wondering if there was recommended maintenance to verify the array is working properly. Right now, I am moving data to the array so quickly that I am backing up every few days between three hard drives. (Back-up #4 was written to Drive #1 after Drive #1 was reformatted.) I am aware that I could use rsync. (Which I currently use for backing up my portable USB HDD to the RAID array.)
So I am using rsync (3.0.7 on MAC OSX) to backup one hard drive to a folder on another one. The is USB drive to USB drive and I have done the initial backup from one drive to a new formatted other drive with the following command:
Code:
rsync -avX --progress /Volumes/Source /Volumes/Destination
This all appears to be going smoothly as I type. I am going to write a script to do subsequent backups in the

Is there a way to make my root pw always equal my user pw? If so, is that a Very Bad Idea?
I have been using Debian for around two years now. I have a small home server running Debian stable i386 and keep it regularly updated (once or twice a week I perform apt-get update and afterwards apt-get dist-upgrade). The system was originally installed with Debian Wheezy and afterwards upgraded.
However, after entering dist-upgrade tonight, around 42 packages had to be updated. I agreed and afterwards got some errors. After apt-get install -f, the result is as follows:
Code:
Select allnickolay@tegulicium:$ sudo apt-get install -f

After rebooting the system, I am presented with the Debian Maintenance mode (root password for maintenance or Control-D to continue).
I tried dpkg --configure -a, apt-get install -f and aptitude install -f.
Unfortunately, still no resolution of the conflicts.
I assume this has to do something with the new Jessie 8.2 release ...

I work for a small retail company which until recently consisted of just one location. This month, we will open two new stores.I have been given the task of setting up a VPN network between the three locations and maintaining it.This network will consist of a main data server on the original location which has four client computers.The second location (another part of town) will have three clients, and the third location will have one client, all connected to the main data server (Retail POS system.) This will be a hardware VPN, with the main data server and all of the client computers running Windows XP.I have been working with the telecom company that is installing the phone system and is providing the routers at each location for the VPN.
I realize that since these are all Windows based machines it is not a Linux question, but I know that many of the experts here maintain Windows machines as well in their work. I am not an IT professional (I am a gemologist), but because I have been a Linux user for most of the last ten years, my boss seems to think I could handle this task so rather than contract this work out, he has asked me to do this. I truly enjoy this type of work, but I am concerned that my lack of knowledge is going to catch up with me, even though I do have a fairly good basic knowledge of Linux networking.
My question is simply this: Can anyone here recommend a good book or online training course which will give me the knowledge I need to maintain this system and trouble shoot it? I have searched online and there are literally hundreds of such books and it is like wading through a swamp. With such a small network, I am sure I can learn what I need, but if someone can recommend a good training/reference book that you have personal knowledge of, I would appreciate the recommendation.
