InterNAT field trials

The 5-letter (or less) .NET domain names are being used for the InterNAT field trials. Those provide FREE (as in $$s) allocations of static address space and ASNs for short names. http://ipv8.no-ip.com/cgi-bin/vanety25?a=L&b=U&c=N&d=I&e=_ Local help is available to set up your DSL and/or Cable sub-nets. It is best to have your .NET domain name before you attempt to connect.

nfsroot
by Jonathan Purvis 15 May '04

15 May '04

Hi, I have managed to get my iMac to netboot the Linux kernel. The kernel seems to load fine, but stops with a kernel panic as it can't mount the root filesystem. I'm using the default 2.4 kernel from Debian 3.0. As per the instructions for yaboot (the Open Firmware boot loader that LinuxPPC uses), i set "root=/dev/nfs". Is this what i'm supposed to do to get / mounted via NFS? Is this a sign the kernel doesn't have nfsroot support? I found a web page that suggested i add "fsroot=$SERVER:/export/root", but that didn't help. Does anyone have any ideas? Thanks, Jon

compiling 2.6.5 kernel from rh9 .. a better distro?
by Stephen Pearce 11 May '04

11 May '04

Recently downloaded the 2.6.5 kernel from kernel.org as a tgz source file .. and tried to install on rh9 .. but the new installation fails at boot. I am now thinking of converting to an alternative distro that will allow this easily .. I understand rh has a whole lot of distro specfic stuff which has to be organised .. Could someone advise me on either how to get it going using rh9 .. or which alternate distro would be best ..rh is the one I'm familiar with. Also ..can you install a new distro without a reformat of the disk .. to preserve all my personal files? Lastly, can anyone provide me with a copy of such a distro .. I can pay postage and media cost. Thanks Stephen Pearce

creating directories
by Gun Caundle 11 May '04

11 May '04

I am trying to create a directory in my 'home' directory with my user login. However I can only create a directory as a root user and thus can't use it with my user login. I can use the 'gun' directory in 'home' with my user login. Any help would be appreciated. [gun@LinuxBox home]$ mkdir adelle mkdir: cannot create directory `adelle': Permission denied [gun@LinuxBox home]$ su Password: [root@LinuxBox home]# mkdir adelle [root@LinuxBox home]# exit exit [gun@LinuxBox home]$ ls -ld drwxr-xr-x 5 root root 4096 May 12 08:55 . [gun@LinuxBox home]$ cd gun [gun@LinuxBox gun]$ ls -ld drwx------ 25 gun gun 4096 May 12 08:54 . [gun@LinuxBox gun]$ cd .. [gun@LinuxBox home]$ ls -ld adelle drwxr-xr-x 2 root root 4096 May 12 08:55 adelle [gun@LinuxBox home]$

[gun@LinuxBox home]$ ls -ld drwxr-xr-x 5 root root 4096 May 12 08:55 . As you can see with the home directory, The owner of the directory has read/write/execute access. The group of the directory has read/execute access (No write access). Everyone else has read/execute access (No write access). Incidentally, root has full control of adelle, and if adelle is a user, tough, adelle ony is seen as Joe Public and has read execute access. For security reasons, I would leave it as is (and login as root to create subdirectories - this sort of thing should be automated when a new user is created - each user should have their own directory to do whatever and that should pertain to that user) but if you feel another way inclined want to have full control as a user, then chown gun home chgrp gun home Or else if you want want everyone to have rw access the chmod 777 home I hope this helps. > -----Original Message----- > From: Gun Caundle [mailto:gun@paradise.net.nz] > Sent: Wednesday, 12 May 2004 09:36 > To: wlug(a)list.waikato.ac.nz > Subject: [wlug] creating directories > > > I am trying to create a directory in my 'home' directory > with my user > login.

Xandros 2.0
by Nigel Nguyen 11 May '04

11 May '04

Hi, I have tried xandros for a couple weeks, it nice and easy to install/use. Well, just feel like Andreas, same Yoper but Canadian(i believed they from Canada, Andreas :) ) It recommended for newbies and windows mover as they X/team has tweaked some features to get their own filemanager and the software depository (called XandrosNetwork). Installed stuff outside that is just normal as install on other debian based distro or just configure/make/make install. Overall, easy to use but less "fun" of course. IMO, if yoper has the GUI installation (i havn't tried the 2.0 yet) than Yoper is a clear winner as newbies always scare of text thing thou :) Just a few comments, Nigel Ng. P.S: Do anyone know if Yoper has new zealand mirror for downloading ?

Performance bottle neck?
by Raymond Burgess 11 May '04

11 May '04

I am currently importing a lot of data into a Postgres Database. Initially things where quickish, but now it seems to be running very slowly. I put this down to index scans. The machine is a Dual P4 with 2 GB of ram and a Raid array (14 Fibre Channel Harddrives) Top is reporting the disk cache is 1.7 GB and system idle around 70%. The postgres backend is using 10% to 20% of one CPU. I don't know if the bottleneck is the Disk IO or Ram. What would people suggest I can look at to see what is holding up the process?
