    Linux Mint offers an easy and painless upgrade path through the last 3 versions, which means no more reinstalling to stay current with the latest version. The only catch is that you need the latest of each version, so for 18, you need 18.3 before you can go to 19, and then 19.3 (or latest), until you go to 20.

Imagine that you have a static IPconfigured for ens33 but then the hard disk is moved to a newer system, the NIC could be anything from ens33 to enp0s1, meaning that manual intervention is required to go and update the NIC config file (eg. /etc/network/interfa........

    You can find many ways to specify the VLANin your network configuration but Ifind this is the simplest and quickest. In this case we are talking about a bridged adapter "vmbr0" but it works even if you just had a normal non-bridged interface. The key here is that in vmbr0 you'll notice there is no IP address. We just specify "manual". Below it is a similar stanza for "vmbr0.58" in this case 58 represents the VLAN (change........

  • MySQL Replication/Dual-Master vs Clustering


    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). With a dual-master you just have a different off-set for the keys and you should be good, but of course there is the chance that at some point replication will halt because of an unexpected or unforseen error........

    gnuCash is available for all main platforms, Linux/Unix, MacOS (FreeBSD anyway), and Windows. You can download gnuCash free from here. It does seem to be fairly full featured and somewhat straight forward, but like so many programs it is missing a few key features or things don't work quite right. It doesn't support importation of CSV files, which is a big minus. And the developers rather than wanting to add support have just dec........

  • Debian/Ubuntu/Kubuntu Bash/Console/Terminal/Putty Home and End Keys Don't Work or Produce a ~


    This is a very weird, annoying and bizarre quirk with many distributions, especially Debian. The home and end keys don't work, but it's a simple fix as long as you found this article :) You just have to edit /etc/inputrc: Find the commented lines as shown below: # "e[1~": beginning-of-line # "e[4~": end-of-line *If you can't find the above, just copy and paste the code below into your inputrc, it will en........

  • Windows Vista sysprep.exe /generalize error "The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install Windows, click "OK" to restart the computer, and then restart the installation."


    I wanted to disable the "Administrator" account for security purposes and Iread some "guide" on the internet that recommended that we run "C:WindowsSystem32sysprepsysprep.exe /generalize". I also clicked the option for "Generalize" and the computer rebooted and gave some OOBE error and restarted, and now I get the error above no matter what. I read that some drivers such as ones from AVIRA AV can cause this because they're unsign........

  • iPhone Enable Tethering Manually Update ipcc Carrier Settings/Update via SSH


    Everyone says there is a "manual" way of doing it and then they tell you to use iTunes, but if you're like me, you're travelling on business in a foreign country and your laptop does not have iTunes and you don't have a way of getting it and/or don't want it. For this example I'm using the provider "du" in Dubai, UAE (United Arab Emirates) but this method works for virtually all providers. The requirements in this case to truly "manually update........

  • How to avoid web content hijacking/copying/Force content to be accessed by only 1 domain name


    This is something that happens a lot and it is very dirty, as you probably know each site is hosted on a certain IP address. Sometimes a domain is hosted by a single IP address and the IP address defaults to this very same domain. This means that if someone buys domain abcd.com and enters your IP address (the one of your website) as the A record, your content will show up on their domain as if it was their own. There is an easy way to prevent this by using .htacces........

  • GRUB "Error 2: Bad file or directory type" 0.97 won


    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........

  • Unixbench Score with Glusterfs/Openvz & Quad Core Xeon - Updated with GlusterFS 2.0.8 & Optimized Client Config


    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 Iadded 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........

  • Tyan S2735-8M motherboard/Rackable Systems 1u Server 100mbit NIC not working even when enabled in the BIOS


    Itried everything Icould 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 untilI decided I should test each NIC one by one. Inoticed that only 1 server out of........

  • Have an OpenVZ VPS/Linux Virtual Private Server and nothing works right?


    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. Ichecked my /proc/user_beancounters and found this: cat /proc/user_beancounters Version: 2.5 uid resource held maxheld barrier limit failcnt........

  • Why Apple should thank the jailbreakers and not patch/stop the jailbreaking exploits


    First of all, the iPhone is crippled in many ways, but most of my complaints about functionality have been addressed through the jailbreak, Ican 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........

  • How to unlock your iPhone 3G/3GS


    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 SIMcard you like. You'd really thi........

  • iPhone 3GS 32GB "Harsh Review"


    Yes, Iadmit 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 whyI 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........

  • iPhone has no password/wand manager saving feature in Safari Web Browser


    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........

  • Apple iPhone 3GS and predecessors are leading a revolution


    As much of a computer nerd as Iam, I'm usually a late adopter to technology for a few reasons. Ifeel 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 Isaw all the hype around it and until recently I wasn't a big fan of anything Apple until a few years ago I realize........

  • Nokia N97 review, feedback and complaints


    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 Iheard about the N97 and what a revolution it was supposed to be and it was even compared to iPhone. To........

  • RTL8111/8168B R8169 Gigabit Link slow speeds


    This is the Intel Atom 330 motherboard with integrated Realtek Gigabit NIC (Intel Desktop Board D945GCLF2 Motherboard W/ Atom 330 1.6 GHz Dual Core Processor - Mini-ITX) I cannot achieve more than 15 MB/s, even doing a local transfer through eth0 to it's own IP. 100% 95MB 15.9MB/s 00:06 So this is not a cabling, switch or hardware issue, it seems like a driver or chipset limitation problem. Here is my........

  • SSH Slow Login even with SSHD UseDNS no parameter


    Icouldn't understand why on one system it took a few minutes to get the SSHlogin 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. The reason is Ubuntu and perhaps Debian and other distributions /etc/nsswitch.conf file Edit yours to have the "hosts" line like so (notice that files and dns are the primary resolution choice........

  • Rackable Systems and their Microslice Clustered 1U Servers


    Ithink 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........

  • Writing/Burning a data CD-R/DVD-R or DVD+RW in Unix/Linux


    There's a lot of outdated information and confusion for system administrator's out there. One annoying task for many an Administrator has been backing up data in Linux. You don't need any GUI tools such as K3B or GnomeBaker. Both are excellent tools but for veteran command line users working remotely, using the keyboard is a great and possibly automated way to save yourself pain and hassle. At a later date we'll cover how scripting can automatically backup certain........
