I dread updating the kernel and rebooting to find the Ubuntu graphics aren't working and you have to manually intervene.   This is usually because Ubuntu for whatever reason didn't update the drivers you need (eg. the manually compiled Nvidia Kernel driver that MUST be recompiled for each and every kernel update unfortunately). The most common reason may be that "linux-source" hasn't been installed automatically on my system.  I tried to manually reinstall the........

I really am a Linux fan but my comments here may not show it.  Although I'm quite familiar with Linux CLI to administer servers, I find Linux GUI OS's like Ubuntu at times very clunky. This is partially because there's no such thing as a "self-made" Linux from scratch where the UI was designed by a single team.  Linux is made up of several different projects that are generally completely separate and this lack of integratiion is a key issue that makes things f........

gocr works great and it's simple, just invoke it like so: gocr filename.png The output will be printed to the screen.

A few days ago this happened on multiple Centos 5 servers and apparently anyone using rpmforge was affected by this error and there was no solution other than disabling that repo to fix it.

Fortunately it came back up........

I had a system running a 128MB live CD image with 2.8 gigs of available RAM and the OOM kernel killer went crazy when using dd for more than 8 minutes and kept killing everything.  I've read that this is due to a low-memory issue and paging in the kernel and 32-bit systems with lots of RAM. I even enabled swapspace on my LiveCD and the issue happened 25 minutes into dd rather than 8 minutes, so what gives? Also no swap space was ever used! cat /proc/s........

I like dd, although it only reads it, usually a read test of the entire disk will uncover if your hard drive is bad in some parts.  This is a good thing to do at least once a month, a lot of times bizarre program behavior, laginess and crashing/unnmounting problems etc.. are due to a failing disc and SMART won't know it or indicate a problem: We must also remember there's never a guarantee, I've found that ever since we moved to larger and more platters per drive with 1TB drives........

Basically you should always be 100% sure that whatever IP your mail server sends out with has reverse DNS/PTR records.  Remember that unless you own your IPs then you won't be able to set your own reverse DNS.  Even if you were to create a reverse PTR record on your DNS servers it will be ignored. Reverse DNS is queried to pre-assigned DNS servers of your ISP, so therefore you'll need to contact your ISP/Colo/Hosting provider to do a reverse DNS entry. If you don't have........

Many people aren't aware but recently Dual-Master Replication setups have become increasingly popular.  That's because you get similar features and benefits of having a full-blown cluster (difficult to setup and maintain and requires I believe 3 servers just as controllers).

What this really refers to is gnome-volume-control-applet which is what controls the volume in the panel/indicator applet.

One of the purposes of rsync is to backup whole filesystems and archive them but how can you do that properly and restore things to normal if all permissions and ownerships are not preserved from your root filesystem? It's not desirable to have everything running as root, especially not just for an rsync. The Easy rsync preserve permission solution for non-root users sudo is the answer and all you have to do is edit /etc/sudoers At the end o........

I separated the 2 drives in the RAID 1 array. 1 is the old one /dev/sda and is out of date, while the separated other one /dev/sdc was in another drive and mounted and used with more data (updated).

This is obviously a bug in the r8169 kernel module and it seems to affect a lot of people.  I upgraded to the latest kernel and hope this won't happen anymore, as it is a very serious error.  This is especially serious for those who are running servers with this chipset, who can afford for the NIC to randomly go off-line for no apparent reason?   [655548.189113] type=1505 audit(1277067560.902:5): operation="profile_load" name="/usr/bin/freshclam&q........

This is a great way to reduce MySQL code/mistakes/annoyance when doing things, take for example this statement: INSERT IGNORE INTO sometable(CatName) VALUES("someitem"); Notice the "IGNORE", that is what does the magic.

This is a great way to use your ftp server space, for example on your web hosting account (although I believe many hosts don't allow storage like this), but if you have a VPS/Dedicated Server etc.., this would be perfect.  Imagine how easy it is to work with an ftp account that you can just mount as a normal partition or directory in Linux, it would be great for backups etc..   Name curlftpfs - mount a ftp host as a local directory Synopsis........

My XBOX's dashboard/firmware was from sometime in 2008 when I first bought the system.  I mainly played using composite cables but at my brother in law's house we used HDMI.  The very first time it worked, but then I bought some games that did some update and after that HDMI never worked. The symptoms besides having on sound is that your XBOX will show PC monitor resolutions but won't have any option to say you have a 720P or 1080P display, this means the XBOX firmware is fa........

I've recently used CPanel on the admin side for the first time and have to say I hate it.  Everything from the layout to the functionality screams "hackish".  It just lacks so many common sense features and way of working.

Why would you want to downgrade the superblock?  Old mdadm verisons like mdadm 2.5.6 only use the 0.90 superblock/metadata and new versions use 1,1.0,1.1 and 1.2 superblocks by default. There are some annoying caveats with this, first of all the new superblocks (later than 0.90) CANNOT be read by GRUB, so you won't even be able to install GRUB.  Even worse, old versions of mdadm CANNOT automatically detect arrays even if they were created with a new version of mdadm with th........

Partclone is a great tool that is basically like dd only it does not waste space, it doesn't take the whole partition, yet it does the same thing as dd, only with huge space/cost savings.

Do you have an LGA1156 board and wonder why your onboard video isn't working?  It's probably because there is no GPU integrated on the board itself, it is supposed to be on the CPU and new CPU's from Intel don't come with it!

I'm not impressed with this motherboard, I was impressed with my Gigabyte AM3 board which seems to work flawlessly. Everyone knows that the firmware is flawed, even though I have the F6, it still seems that the system doesn't reset properly or quickly enough. Another HUGE problem is that in most Linux kernels the NIC won't work (if you try 10 times by rebooting it might).  I also notice that you need to power down for it to work.

Proxmox has made this free utility to backup running OpenVZ containers.  It's a great program which is actually just a PERL script but gets the job done.  This program is not 100% required because all it really does is cp -a from your container's path as far as I know but it is still good to have uniformity to how you backup your containers.

For example, Memorex along with any other 'brand' is actually always made by another manufaturer including CMC Mag........

There are also some countries such as Sweden that offer high speed connections, but the high speed only applies locally. The reason is that man........

I was starting to panic because suddenly my 1TB Seagate SATA drive wasn't working, I thought it was a BIOS issue because it seemed to have happened after I tried overclocking my Desktop too much. I tried powering down and waiting, but I still couldn't hear the drive spin up at all.  I tried a second 1TB hard drive and it wouldn't work either.  I checked all power connections again and again until one of the pins in the MOLEX connector popped completely loose. Th........

You can see the problem below, GRUB recognizes my hard drive and sees the partitions but cannot access them.  This is from the GRUB boot disc I'm using. What happened is that I had some power issues causing this system's power to be interrupted several times and basically an on/off on/off situation. The system won't boot, I just get a flashing cursor and no message or error from GRUB.  Obviously the problem is that my MBR seems corrupt or some other issue. My........

The results are still not flattering and are nothing close to native performance.  Unless GlusterFS has a "DRBD-like" option to delay writes over the network and to only read from the client side, I don't see how performance can ever improve much more. After doing some client optimizations I added more to the score:   Start Benchmark Run: Sun Nov 29 00:37:44 PST 2009  00:37:44 up 3 min,  1 user,  load average: 0.01........

I've tried to find a good sensible solution to cluster with and each technology has it's pros and cons and there is no perfect solution and I've found a lot of "exaggerations" in the applications, benefits and performance of these different filesystems. DRBD I first started off with DRBD and I have to say it does live up to the hype, is quite reliable (although it can be annoying to match up the kernel module and user applications since they must match and whe........

You might remember my original GluserFS/OpenVZ benchmark which produced a horrible 29.8 This is the exact same system, but using the latest 2.0.8 (with some small files patch which speeds up performance) you can see it is about 25% faster. I also haven't tuned my config files at all, but there are some settings that should increase performance on small files which I believe i........

I never saved any of the logs, but basically no matter what OS (Linux) I used, I could not get my 1000GB hard drive to work (Seagate SATA).  The BIOS recognizes the drive and fdisk -l shows the hard drive as it should. The tricky thing is that different OS's will give you different results, but don't be fooled.  You can't use these larger drives for long.  I was getting all kinds of seek/IO errors and also messages that the port could not be read.........

I tried everything I could think of, and of course even with the NIC enabled in the BIOS nothing was working.  The light would flash when you plugin the cable for a second, but that's all. Due to another issue I'm about to post about (server is not compatible with 1TB/1000Gig Hard Drives), I updated the BIOS.  I didn't even know the 100mbit NICs were not working until I decided I should test each NIC one by one. I noticed that only 1 server out of........

This is very disappointing since GlusterFS markets itself as a solution to deploy VPS servers on.  On the HN itself I get a Unixbench of about 360. I'm also using an SSH tunnel to secure the communications, but even before that, things seemed very slow.        #    #  #    #  #  #    #          #####&n........

In those 4 simple commands you can setup mutual key exchange between two sshservers by using a single login shell session and single window. *Just change the IP address examples of (10.10.0.2) to the target of your mutual key exchange.  It doesn't matter if the server is on a LAN or WAN (well unless the server is behind a firewall and you cannot SSH into it).........

I was getting really annoyed with this, I used full quotes around the filename and vi, cat, less all thought I was trying to pass the dash in the filename as an argument. I didn't realize that all you have to do is just put a dash dash "--" in front. Here's an example: cat -- "-etc-glusterfs-glusterfsd.vol.log" Without the -- you get: cat: invalid option -- c Try `cat --help' for more information. I h........

Have you ever seen this dreaded message in your Apache/HTTPD /var/log/httpd/error_log? [error] server reached MaxClients setting, consider raising the MaxClients setting The error itself is slightly misleading.  I believe this happened to one of my servers, I found Apache was running still, and that you could telnet to port 80 but no respnose would be given. For some reason my error log initially did not have the above error, but after a restart I saw........

This way should work on all Linux machines, at least RHEL/Debian (Ubuntu) based distros but most likely all and also should work on many Unix style machines I believe. Many OS's have tools to update the timezone, but most of them (even if command line) require several bloated packages and even Xorg/KDE based packages etc.. Your time zone info file is actually in /etc/localtime if you open this file in vi/vim/pico you'll see it's gibberish (binary code or another encodin........

For some reason I keep getting this error when trying to run a sudo command eg: sudo -u someuser somecommand sudo: Error dropping capabilities, aborting My version of sudo is: sudo-1.6.9p17-3.el5_3.1 and I've heard that version 1.7 fixes everything.  The only thing is yum does not think sudo has any update.  I guess the new version has not been committed to the RPM repository yet. This is really a huge and ann........

A VPS Server I had just wasn't working right, code that I migrated there just wasn't working.  For example, it kept telling me the connection to the database was unsuccessful, halfway through iterating through results it already had. Then I realized it wasn't my code.  I checked my /proc/user_beancounters and found this: cat /proc/user_beancounters Version: 2.5 uid resource held maxheld barrier limit failcnt........

It's actually very simple and "grep" makes it as easy as possible.  I'll outline a few common scenarios and provide some examples. Say you want to search ALL files within the current directory (and inside/deeper) for the text "phpinfo()" grep -R "phpinfo()" * If you want to search only certain files such as only .txt you would do this instead: grep -R "phpinfo()" *.txt As you ca........

I was getting very frustrated one day wondering why it appeared my .htaccess file was being ignored and not processed by Apache.  No matter what I did it was obvious that Apache didn't care about my .htaccess file.  Then I realized that the default settings must be in effect, which is that my vhost didn't explicitly allow me to override the default settings. This usually comes down to your vhost settings. Make sure you have an entry like this in your Apache vhost settings in........

To enable Fuse to work inside a OpenVZ container it's very simple (although some people say it can't be done). Remember that on your HN (HostNode) for OpenVZ, Fuse must be installed and the module must be loaded for this to work.  In addition remember that you need the Fuse package installed inside the container of course. vzctl set 2000 --devices c:10:229:rw --save vzctl exec 2000 mknod /dev/fuse c 10 229 The part that most people forget........

This is something that annoys a lot of people, fortunately the Redhat style OS's are the most simple in this respect.  I disagree that Debian's way makes sense, it is more of a hackish approach in how they implement iptables. Anyway, for those who are using Redhat/Centos style OS's it is very simple. Set your rules from the shell/command prompt and to save the iptables firewall rules so they are remember/loaded on boot just run this command: service iptables........

As shown below you can find ringtones in the "/private/var/stash/Ringones*" directory of your iPhone. Different reports have said that the .m4r format is really an MP4 file and some have said AAC and some also say "it's the same as the M4A" format.  Whatever the case is, one easy way is to install the silent theme from Cydia and copy that into your ringtones directory.   /private/var/stash/Ringtones.sh7cLj root# ls Alarm.m4r ........

There is a tool called "xml2" which will parse both HTML and XML scripts, this is very useful to do a mass extraction or conversion of data based on say an HTML table etc.. It becomes even more powerful using bash if certain tags are identified with a certain class="" attribute or something else unique to only the tags you want. Happy parsing.........

Here is an example that I recently found, most PR checkers will say this domain is PR8 or will say "cannot analyze PR". The example is domain "bonserotica.com"  view Google's cache of the homepage and you'll see as in the picture below, it lists a different URL, which means they used a redirect to a high PR site to fool you and the PR checkers.........

There have been lots of reports like this going around and I can confirm my 3GS with 3.0 firmware is overheating as well.  It gets quite hot and actually can make your head or hand sweaty when holding it to talk, or simply holding the back cover for any reason. It's a wonder how the device cools itself at all, considering the only thing that could ventilate air are the 2 speakers at the bottom or the single speaker on the front of the device. Apple seems to be making........

This is pretty bad, ever since my phone has been unlocked the battery life is horrible.  Many others have reported this issue on provider unlocked phones and even jail broken phones.  We're talking issues as bad as losing 1% every 3 minutes which is what I seem to have observed as well. For now I'm going to relock the phone, and hopefully a firmware update will address this issue.  This is very annoying and it seems apparent this is also happening on 3G phones and that........

Has Apple tried to give a golden egg to the cell phone companies?  Has anyone noticed that if you set your lock time to x minutes, the phone doesn't just lock, it goes into standby.  When it does this, any WiFi connection you have gets dropped and all push/data functions such as e-mail checking are done through the 3G network. There is no way to change this feature and functionality and it's very annoying, especially if you are downloading something or loading files over the........

You need to jailbreak your phone and inside Cydia you'll find "PushMod" which will allow you to set your mail check time to 1 minute instead of 15-minutes. This is a great mod and has saved me a lot of stress and frustration, the lack of Blackberry style "free push service" makes iPhone less attractive, but this solves that. Apple needs to make mobileme free and have a Blackberry style chat network to compete, I'm not willing to pay for something Blackberry........

First of all, the iPhone is crippled in many ways, but most of my complaints about functionality have been addressed through the jailbreak, I can run apps in the background of my choosing, I can install a terminal, acccess my phone through SSH and SCP and so much more. It even addresses the 15 minute e-mail problem, I installed a program called "PushMod" and now set the checking time to just 1 minute. Apple should really thank the developers for this gift, it ma........

Everything was working fine but I believe when I turned off "EDGE" in Big Boss everythign went haywire, at first my WiFi dropped, then 3G didn't work and I couldn't even make phone calls. If you're having this trouble with your jailbroken 3GS running 3.0 firmware, make sure you don't turn off EDGE, it seems to disrupt all service to your phone.........

First of all you need to be jailbroken, but this is not covered here. Go into Cydia and click "Manage Sources" then "Edit" and add: repo666.ultrasn0w.com Then search for "ultrasn0w" as a package and install it, that's all there is to it, your iPhone is finally unlocked so when you travel abroad you can avoid ridiculous roaming charges, or you can switch providers and use any SIM card you like. You'd really thi........

Apple crippled the iPhone by not allowing multi-tasking of the non-primary apps.  I use SSH a lot and I don't want to close my session just to check my e-mail, etc, now an app found in Cydia called "Backgrounder" allows just that. Although it's not perfect, we installed the correct one for "3.x" iPhones and hit "Reload SpringBoard" and the hour/circle glass has just been going for minutes. It seems like it installed fine even with the crash t........

This happened during a sync of my iPhone while installing some apps.  This usually happens to non-jailbroken iPhones who are trying to install non-Apple approved software OR jailbroken phones who haven't done the "Sync update".

Truly, the only way to unleash the capabilities and customization abilities of iPhone are to jailbreak, it's not just for hackers anymore. A few days ago someone by the named of "geohot" released a single click application called "purplera1n", which does the entire operation smoothly and seamlessly. In our case, the first time it went as far as "done, wait for reboot" on our Windows machine and for minutes we waited and saw the pic on the iPhone w........

Yes, I admit I finally got bitten by the hype as much as I can usually see through it all.  Keep in mind this review is of the "stock" phone, no jailbreaking yet which is what really unleashes the customizability and why I bought iPhone. I had better things to say about this phone before buying it, and it is a great phone, perhaps the best on the market by far, if not because of the Mac OS port onto the iPhone and all the apps, etc, etc. With that said........

I kind of expected this feature to be there in some form, to stay ahead of the pack Apple needs to stay on top of this.  User's of HTC's Android smart phone which uses a Linux based OS with Google's power behind it, note that you can save passwords in the browser on that phone. Apple needs to continuously evaluate the needs in its core apps and make sure the features are cutting edge and top notch, if other phones come out with some of these seemingly small but essential features........

This is unfortunate and frustrating as many sites use it, a lot of people are frustrated that TinyMCE does not work on the iPhone Safari browser. Apparently the developer of TinyMCE's answer is "talk to Apple about it" It's really frustrating although, I wonder if any other mobile phones are able to use TinyMCE or not, whatever the case is it would be nice to find a solution to use TinyMCE on the........

The dmg format is silly and annoying to work with, why couldn't Apple stick with the .iso standard?  Anyway, there's an excellent Linux and Windows based tool to convert it back to a normal .iso Image called dmg2iso I'll only cover the Linux version although the Windows pre-built binary works the same way. Download dmg2iso here for free (from the author's website) It's just silly and doesn't make sense that Ubuntu doe........

As much of a computer nerd as I am, I'm usually a late adopter to technology for a few reasons.  I feel most new hyped technologies and electronics are mainly fads, and I'm also cheap. Adopting later means you avoid the bugs, kinks and most importantly pay the lowest price, that's me being cheap again :) I never read much about the iPhone but I saw all the hype around it and until recently I wasn't a big fan of anything Apple until a few years ago I realize........

I've had an old Blackberry for a few years and I was ready to spend some serious cash on a nice Nokia.  I love the idea of the Linux based Symbian S60 OS, so I was looking at phones like the E63, E71 (both are basically the same, at least CPU/screensize although E71 is thinner, has a 3MP camera, has GPS, and has dedicated buttons to adjust the volume). Then I heard about the N97 and what a revolution it was supposed to be and it was even compared to iPhone.  To........

I couldn't understand why on one system it took a few minutes to get the SSH login prompt when connecting to other systems. The other systems all had the UseDNS parameter set to no, which almost always resolves the login prompt delay.

This is really something the SSH Server developers should consider.  The cause of this annoyance is because of failed DNS lookups on your IP address, which is especially common for many dedicated/col-located servers and also computers on internal NAT/private networks.

When trying to even cd or ls the mounted OCFS2 partition it crashes.  I think this is a combination of VMWare Server's problem and the way I mounted and symlinked to it.

There's a lot of information and guides on OCFS2 for RHEL and Centos Linux but the package setup and configuration is slightly different and this has thrown some people off.

This will give you the basic info needed to browse and connect to Samba shares from the command line.  From the GUI of Gnome or KDE etc, it is pretty standard and straight forward.  However, I've found very little guides on how to do it from the command line and if you're like me, a nerd who prefers command line for its simplicity and for remote use, this is the way to go. First get a list of all the Samba/SMB shares on the target. smbclient -L hostname........

I've read a lot of people complaining that their 1U servers are too loud for the office, home or whatever strange places people might want to put them. Whenever I see the question asked, "what can be done about the noise", you'll see a myriad of silly answers like "you shouldn't have it at home or in your office at all", "1U servers are meant to be loud". These all might be valid points but they're not the solution.  A good example is a........

I think there has been a lot of negative press towards Rackable Systems.  We will give their new solution credit that it is marketed very well, and comes prepackaged and ready to go. But let's cut through the hype of both sides, the people who love this concept and the people who hate it. What Rackable Systems have done is a first, to minimize space, power and costs into small servers.  This is great, and many companies have already built their own servers based........
