Last week when I was at a festival, my macbook unfortunately ran totally out of space, and there wasn’t much I could delete. With almost 20 gigs of SD cards, the only thing that could really take the chop was my XP boot camp partition.

Cut a long story short, I’ve now got a much bigger drive (500 GB) for my macbook. Along with the release of Windows 7 RC1 being released I thought I’d give it a try with boot camp.

Installing is pretty easy, burn the Microsoft ISO to a DVD, and follow the normal guide. I detest the fact that I need to burn another CD, or use my OS X Install DVD (which I can never find) to get the boot camp drivers. If like me you’d like to download them, I’ve given a link below to where you may find them. I just put them on a usb stick.

Once installed, pretty much everything works under boot camp, the only thing I found that didn’t play was the ‘Reboot into OS X’ I get an error. This isn’t a huge problem, as you can just hold the alt key on boot up to select OS X or Windows.

Once I got all that working, I then wanted to get the same build / partition under VMware fusion. Reading a few guides, the best way is to follow the normal guide for XP, but change it so the guest is set to Windows 2008 Server. Again, all working pretty well once you install VMware Tools.

The only problem that I did have, is there was no networking for the guest. The NIC just showed as Ethernet Controller. Nothing seemed to get this NIC working, tried manually installing the drivers from the VMWare tools cd, copying from another Windows 7 guest.

The only thing that seemed to fix it, was to shutdown the guest, and add a second NIC, and boot back up. Windows 7 RC1, installs this NIC with no problems at all, and all is working. Intererstingly, it still wont play with the original one. None the less, it’s all working through it’s second, new NIC, so I am happy with that.

A friend told me of a magical cross platform application, which I’ve been using for a while, thought I’d share. Synergy;

“Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It’s intended for users with multiple computers on their desk since each system uses its own monitor(s). ”

The picture above shows my very small desk, sporting 2x 22 Samsungs, and my Dell D420. Under the desk is an old HP desktop powering the two monitors (and soon to be 9′ touch screen above them, when I get the drivers setup). I rarely use the D420 these days, as I use my MacBook or Advent 4213 notebook when out and about, so didn’t mind giving it up to the desk.

I can use the keyboard and mouse on the laptop, to control both it, and the bigger screens. The neat thing is, with the config setup correctly, I can just move the mouse upwards and the pointer magically moves to the other screen, and the keyboard then controls that computer too. A few other neat options are to have a shared clipboard, and to activate the screensaver/lock screen across all computers with each other.

So on my tiny desk, I can fit in quite a lot of screen real estate. As for using the laptop as a primary keyboard, I started to do this at work when the hotdesk keyboards started to freak me out, and using the laptop keyboard is actually quite nice to use.

Have tested Synergy with os x, and all worked pretty flawlessly there too. Not had a chance to test under windows just yet, as rarely use it these days, but from what I’ve read it all works fine.

So I am meeting a friend for coffee and lunch today, unfortunately she’s running a bit late, so decided to grab a frappacino and be one of those geeks in Starbucks with their laptop/netbooks out.

I’m in the process of swapping out the wireless card in my netbook (for osx86) so don’t have any drivers or modules setup in the OS’s at the moment.

Luckily though, I do have a vodafone data sim, and the 4213 has an inbuilt 3G modem.

Here comes the fun part, the data tariff is on Vodafone business, so you would think they’d be slightly reliable… erm nope.

Every month, without fail, they mess up the billing. Apparently my Direct Debit fails, it doesn’t. A few ways I know, is it’s gone through a couple of times, so we know that it’s got the correct details. The other being when a DD does bounce, my Bank arse rape me on charges. Third being, there is always funds to cover all my DD’s.

Now vodafail, are funny people, because you know how I said it’s a data card, well how do they try to contact you… by txt message. That’s a big clever idea.

I can sort of see the idea, in that their app for windows, does have a sms function, but I would at least have thought an email may be a better option? or even both. However, I don’t use windows, instead my netbook is running Fedora 10, and NetworkManager doesn’t support sms… FAIL

The best one is when I do look at the missed call txt’s, from their sales drones. WTF? do they talk binary? no, well don’t call a datacard then!

Bah, alas, I phone them up, and go through the usual crap of, could we take your mobile number (No, I don’t know it, I never have, and have no intention of, it’s a datacard.) Can I have the account number, it’s on your bill (No, it’s a datacard, I use it when I am out and about, I don’t carry a copy of all my bills with me)… so we eventually get there, and they say to switch my PHONE off and on… FAIL.

Alas I am mobile again, thanks to the friendly folk at vodafail.

Hmm, the contract runs out next month, who should I move to?

This is an admittance of failure, by one party, me. Today was working on a load of issues at work, and lost access to my home IM server. This usually means network manager on my laptop has dropped the VPN, and just need to redial.

However today, slightly different, in that my VPN GW had fallen over. Luckily this is a virtual machine on one of my servers in London, so just have to reset the guest via VMWare. Unfortunately, this is on one my older servers, still running VMWare Server 1.x, and also for added fun, I can only access the Host via the VPN, seeing the problem here?

Well I do have a ‘backdoor’. Anyways I digress, whilst I was resetting the guest, I thought I’d take a look at what snapshots I had for it.

After clicking the second button, I quickly remembered, VMWare Server 1.x, only has one snapshot. Oh dear, within  a blink it was restoring to the previous snapshot, with no way to stop it.

Checking further, this snap shot was old, very old, about 3 months old. So it booted back up. Here comes the second fail. The server in question, happens to be the master, of my MySQL servers, so decided to quickly replicate it’s self, wiping all the new data from the other nodes. Is also my primary NS, so replicated those too. It also does a shit load of other things, that I wont go into, but that broke lots too.

Alas, shouldn’t be a problem though, as I have a four hourly rsync of the configs taken, and replicated off site. Here comes the third and forth fail. 3) the MySQL dumps, appear to have stopped working, looks like there was a regression in one of the scripts. 4) I’d been working on the offsite nas a few months back, and didn’t want the rotation of backups to occur whilst I was doing the work. You guessed it, I forgot to switch it back on. Fuck!

These are all my own fault, I have no way to deny. I spend most of my working day fixing other people’s silly mistakes like this, and setting up systems / procedures so this doesn’t EVER happen, you’d think I’d actually tick a few things off my personal to do list, huh?

Nevermind, managed to fix it all in the end, well mostly… fail fail fail fail fail

Do your server(s) hang when they reboot after windows updates are applied? A lot of mine seem to, and usually it’s becuase one process gets stuck when it receives the kill signal… usually the windows update process.. If the server is in a remote location, can be a complete arse. There is a quick and dirty way to get around this.

Rather than rebooting as normal, or pressing the reboot now button on windows update, open up a command prompt (Windows > Start > Run > type cmd) and type the following:

shutdown -r -f -t 1

As shown below;

The syntax is as follows;
shutdown == runs the shutdown process / app
-r == reboot
-f == force apps to close (so the process that gets stuck, gets forced to close)
-t 1 == time to delay before rebooting, in seconds. I choose 1, as I don’t want to wait around, pick whatever suits you.

Happy patching.
