  • Citrix: Resolve SSL Error 61 on Windows

    Some weeks ago, I had a user call in, saying that she got the following error message when trying to launch applications from our Citrix farm:

  • Disconnect non-mapped drive

    From time to time, I have been unable to connect to the UNC path of a network share. The error message I get is:

  • Internet Explorer: Search in the address bar does not work

    A while back, a user called in, complaining that he was unable to use the address bar to search, in Internet Explorer 10. He further reported that he had just upgraded from Internet Explorer 9. I originally thought it was due to problems with a plugin, so that was where I started out. After looking at all of them; enabling and enabling, restarting IE and so on, I had gotten nowhere. At all.

  • Security database trust relationship revisited

    A little over a year ago, I showed you how to fix a broken trust relationship between the client computer and Active Directory. That post has since received a number of comments, and I will address some of them below: (more…)

  • Mac OS X: Change what programs load on startup

    I like having my Mac start a set of programs each time I boot it, yet there are others which, under normal circumstances, would be set to load on boot that I only want to be running when I want them to be. Luckily, deciding what programs to start on boot – or not – is a simple enough proposition. Here’s how: (more…)

  • One important difference between Debian and Fedora

    Before starting out with Oracle Linux this summer, my experience with Linux had been more or less confined to Ubuntu, which stems from Debian. Oracle Linux, on the other hand, stems from the Fedora project and Red Hat. Though they both build on the same kernel, they diverge from each other in a few important aspects. Software available in the repositories for Debian are divided into free, non-free and contrib. All software available in Fedora’s repositories are free.

  • Oracle Linux: Unable to connect to FTP server in terminal

    In order to keep the virtual harddrive on my VM as small as possible, I prefer keeping installers on a network share that I can connect to through FTP. The terminal command for connecting to FTP servers handily enough is ftp. When running that command, terminal returned “Command not found”. It turns out that FTP is not installed on Oracle Linux by default.

  • Oracle Linux: Unable to connect to the internet

    When first installing Oracle Linux, you may run into being unable to connect to the internet. You may make the mistake of thinking that the problem is with the network settings on the host-side, and try to futz about changing what type of network connection the VM connects to. Don’t bother, it isn’t going to do any good, and you will only get annoyed.

  • Force uninstall when installer is unavailable

    Imagine the scene; you are having a problem with a program, and the manufacturer tells you that the solution is a complete uninstall followed by a reinstall. You go to uninstall, and Windows tells you that it can’t find the installer. Looking around, nor can you. So, now you’re up a certain waterway without a certain rowing implement, aren’t you? Not necessarily.

  • Oracle Linux: Insufficient memory to auto-enable kdump

    Remember how I said “you should be all set”, last week? Turns out, I was only partially right. After creating a local user account, Linux also configures kdump, the kernel crash dumping mechanism. When attempting to do so, it returned this error message:

  • Starting out with Oracle Linux

    I have been wanting to learn more about Linux for some time now, and the time has come to transform a desire to action. I have landed on Oracle Linux, for reasons that will soon become clear. As I don’t have any machine to dedicate to this, and because I want to have the ability to take snapshots and revert to previous states, I will be running Linux as a virtual machine.
