Speed of network copy

I needed to copy some big video files from my NSLU2 NAS box to my desktop a couple of days ago and noticed that, using Konqueror, the FTP protocol was significantly faster than using SMB. * Using ftp://192.168.n.n/DISK 2/video/… gave me around 5.5MB/s * Using smb://192.168.n.n/DISK 2/video/… gave me around 3.5MB/s Of course, the NSLU2 is constrained mainly by only having a 10M network interface but this is a very significant difference in speed.

Mounting disks by ID – Redux

OK, maybe I was a bit harsh with the verdict on mounting by UUID in my last post. Having played further with trying to get the right disk to boot by default, I realised that there is something rather odd about my ASUS motherboard. I seems to want to boot SATA drives in REVERSE order so that SATA disk 3 is booting before SATA disk 1 no matter what order I tell it boot in (via the BIOS).

Distributions January 2008

I was getting very frustrated with SUSE recently. Mainly because of the slow and flaky package management but also due to my scanning difficulties. So I decided to do a quick test of a couple more Linux distributions. Here are a few quick notes. MEPIS 7.0 Release 3 There is a password on the Live CD login with no information on what it is (guessed demo) Install to disk has to run as root – it silently logged when run as demo with no indication as to why In the disk partitioner, there were no partition names or labels to give a guide to existing partitions – both SUSE and Mandriva give better information No wizard to help install my Wacom graphics tablet (this works great under SUSE) THERE IS NO SETTINGS WIZARD FOR NVIDIA!

Mounting disks by ID

One think I discovered in my January foray into other distributions is that mounting disks by ID which is now the default in many distributions (such as SUSE and Ubuntu) is not such a good idea when you might be ripping some out. In fact, Linux does not seem to take kindly to having hard disks ripped out at all! I had to manually edit the device.map, menu.lst and fstab files of my existing distributions to get them working again after removing my two PATA drives that have driven me mad with buggy GRUB configurations.

Things to dislike about SUSE 10.3

OK, so we’ve have the good things about openSUSE 10.3, now for the bad. * The repository and package installation management in openSUSE 10.3 sucks – bigtime! * I’m often getting failures to read the control files from the Internet (though normal browsing works fine), * it is slow – really very very very slow, * and you do seem to get weird dependency issues more often than other distros, * there are too many fairly standard packages missing from the default repositories so you have to configure third party ones (at least this is often easier with the 1-click install facility now available), * 1-click install seems to often fail or takes >5 minutes to jump into life, * Why do I have to keep importing new repository keys?

More on the GRUB bug (with mixed PATA and SATA drives)

I’ve mentioned this one a couple of times so I’ll give a bit more detail because it is a nightmare to solve if you don’t know what is going on. If you have both a parallel ATA (PATA, this is the way most hard drives were connected on desktops and laptops until around 18 months ago) and a serial ATA (SATA) hard disk controller on your PC (as many do) and hard drives connected to both controllers, you are going to get hit by the GRUB PATA/SATA bug.

Things to like about openSUSE 10.3

It works well out of the box. Things it doesn’t do wrong I didn’t need to get round the GRUB bug since SUSE treats PATA and SATA disks as pseudo SCSI disks and nothing gets confused when rebooting. It didn’t kill my graphics card with a buggy NV driver. My Soundblaster Live card works correctly with digital output and everything. My old, serial connected, Wacom graphics tablet just works. Once installed, Compiz Fusion just works.

Distributions December 2007

Linux is a very fast moving landscape so I tend to do a major update of my systems once or twice a year. Although I moved over to Linux at the start of 2007, I decided to do another move in December as my main installation was getting rather tatty from too much experimenting! So I went back through the distributions that I had looked at before, namely: * Ubuntu (along with the variants Kubuntu and Mint) now at 7.

Welcome

Having finally made the switch on my personal machines from Windows to Linux early last year, I decided I’d like to share my experiences of “living with Linux”. As an IT professional, I’ll probably never be completely free of Windows, I use it all the time at work so I’ll also be looking for tools that work across both platforms. Regards, Julian.
