2016-06-18 DSC vs. GPO vs. SCCM vs. MDM

Microsoft Windows administrators now have a number of ways for managing their estates. Group Policy (GPO) Allows very fine-grained control over every aspect of Windows. Primarily aimed at Windows desktops. Requires Active Directory (AD) and very careful configuration. Requires well trained specialist staff to get it right. System Center Configuration Manager (SCCM) Allows central control over software delivery. Also requires AD. Configuration of delivery packages can be complex and very careful change control is required.

2012-05-05 SSH Error: “ssh_exchange_identification: Connection closed by remote host”

Fixing up an SSH login error after moving to a new ISP. "ssh_exchange_identification: Connection closed by remote host" is caused by the lack of a reverse DNS entry.

2009-08-13 Flashing the BIOS from Linux (OpenSUSE 11.0)

I’ve been a bit quiet here recently because I’ve mainly been working with my business laptop currently running Windows 7. You can see more about this on my other blog – Much Ado about IT. However, the power supply on that died recently so I’m back to my trusty desktop which runs OpenSUSE 11.0 24×7. I managed to get hold of an upgraded CPU for this a while back but I’ve not really had an incentive to upgrade till now.

2009-04-27 Version Control for Mortals

Version control systems (VCS, or Revision Control Systems or Source Control Systems) are designed for software developers. They enable one or more people to work on source code, annotate changes, split and merge the code, link to bug tracking systems and a number of other things that are interesting to developers but not to most people! Indeed then, for most people, you might expect that version control systems are not interesting at all.

2009-03-06 Sun’s VirtualBox gets on with it!

Yep, I keep being amazed by the quality of VirtualBox which is now owned by Sun. I need to set up a virtual machine to test and demo Sun’s Identity Management (IdM) suite and it needs to be usable with VMware too. So I headed over to the VMware Appliances web site and downloaded a pre-canned Debian 5 server. This is recognised fine by VirtualBox! I gave the VM a Host Networked connection to the network and with no further configuration, fired up the VM.

2009-02-11 Update

Hi, thought I’d better put an update on here as to why I haven’t done any posts here recently. Well, I’ve not done much with Linux recently. My OpenSUSE 11.0 desktop machine works and does pretty much everything I ask of it. At the moment, that is largely managing my photographs and not much else. This is because I’m out and about on a big project and so I’m using my monster laptop (Dell M1710) and that is running Vista as I have to be able to run Outlook, OneNote and other MS Office applications at full speed.

2008-08-14 Shell script to Back up critical files (using RSYNC)

Following up from my article on backing up USB drives, this recipe backs up the critical files on my desktop to remote storage (a NAS device on my network). Note that PC2 is the desktop to be backed up, SLUG1 (192.168.1.2) is the NAS device and USER1 is the user id doing the backup. #!/bin/bash # Backup Key PC2 files to Slug1 # Sync 2007 picture folders ##rsync -rl /home/user1/pictures/2007/ user1@192.

2008-08-14 Automatically Backing up a USB Drive with RSYNC (KDE)

USB Drives of all kinds need to be backed up and the best backup is an automatic one (it’s the only way to make sure that it gets done!). So here is one recipe for doing just that using RSYNC and some BASH scripting magic. I’ve split this into two files. You don’t have to do this of course and one may well be better for you. I used two because I can run the second one manually as well.

2008-07-17 Font sizes and DPI

This seems to be a problem that won’t go away. It seems inordinately hard to get a good looking set of fonts of the correct size. It is not that there aren’t some nice fonts available; there are, at last, some fonts under Linux that often look superior to the Microsoft ones. It’s just that it is difficult to get the whole look and feel correct. This is especially true when mixing Gnome based applications (Firefox and Thunderbird for example) and KDE.

2008-07-15 Thoughts on OpenSUSE 11.0

Here are my experiences installing OpenSUSE 11.0 on my desktop PC (I had already successfully installed it on a VM). I opted for a KDE 3 desktop – I don’t like Gnome especially and KDE 4 is not ready for day-to-day use as far as I am concerned. No problems at all with mixed IDE/SATA drives and GRUB 😉 * Usual problems with NVidia drivers (corrupt screen on first entry to KDE).
