My Peavey combo amp

A few pictures of my Peavey BACKSTAGE 2 guitar combo, with 'Transtube'. Sounds great, and at 10 Watts - I must turn the volume down to 10% or less to avoid being killed by the neighbors :)

Installing Slackware Linux on an EeePC 701 by PXE

Just a few notes on this matter.
I've used my notebook (running slackware 13.0 too) as a pxe server to install slackware on my Asus EeePC 701.

- Install dhcpd

slackpkg install dhcp

- Sample dhcpd config:

floyd[~]$ cat /etc/dhcpd.conf 
# dhcpd.conf
#
# Configuration file for ISC dhcpd (see 'man dhcpd.conf')
#

option domain-name "eulinux.org";
authoritative;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
ddns-update-style none;

allow bootp;
option tftp-server-name "10.0.0.1";
next-server 10.0.0.1;

subnet 10.0.0.0 netmask 255.255.255.0 {
    option domain-name "eulinux.org";
    option broadcast-address 10.0.0.255;
    option subnet-mask 255.255.255.0;
    option domain-name-servers 192.168.2.1;
    option routers 10.0.0.1;
    range dynamic-bootp 10.0.0.50 10.0.0.100;
    use-host-decl-names on;
    if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
 filename "/slackware-13/pxelinux.0";
    }
}

- Mount the slackware 13.0 .iso to some folder, and copy a few files

root[floyd]# mount -o ro,loop -t iso9660 ~/iso/slackware-13.0-install-dvd.iso /mnt/slack/
root[floyd]# mkdir -p /tftpboot/slackware-13/
root[floyd]# cp /usr/lib/syslinux/pxelinux.0 /tftpboot/slackware-13/
root[floyd]# cp /mnt/slack/isolinux/message.txt /tftpboot/slackware-13/
root[floyd]# cp /mnt/slack/isolinux/f2.txt /tftpboot/slackware-13/
root[floyd]# cp -a /mnt/slack/kernels/ /tftpboot/slackware-13/
root[floyd]# cp -a /mnt/slack/usb-and-pxe-installers/pxelinux.cfg_default /tftpboot/slackware-13/pxelinux.cfg/default
root[floyd]# cp -a /mnt/slack/isolinux/initrd.img /tftpboot/slackware-13/ 

- Sample pxe loader config (/tftpboot/slackware-13/pxelinux.cfg/default):

default hugesmp.s
prompt 1
timeout 1200
display message.txt
F1 message.txt
F2 f2.txt
label huge.s
  kernel kernels/huge.s/bzImage
  append initrd=initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=huge.s
label hugesmp.s
  kernel kernels/hugesmp.s/bzImage
  append initrd=initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=hugesmp.s
label speakup.s
  kernel kernels/speakup.s/bzImage
  append initrd=initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=speakup.s

- Also we must export /mnt/slack/ directory by nfs:

echo "/mnt/memory 192.168.2.0/24(ro,all_squash) 10.0.0.0/24(ro,all_squash)" >> /etc/exports

- Start up dhcpd, start your eeepc, press as the system boots, and choose the pxe boot option.
- The rest is fairly simple, usual slackware install, except that when selecting the source, you will choose "NFS" over "CD/DVD"


Have fun!

RWhoisd, indexer issue on Linux

Getting `sort...` errors when running rwhois_indexer on Linux? (I was experiencing this on CentOS 5)

[root@server html]# /usr/local/rwhoisd/bin/rwhois_indexer -c /usr/local/rwhoisd/etc/rwhoisd.conf -v -A 203.23.23.0/22 -C network -s txt
sort: open failed: +4: No such file or directory
error: sort failed: Success
warning: could not delete temporary index file '': Success
warning: could not delete temporary index file '': Success
indexing failed

This is caused by the parameters used by the indexer when using the `sort` command.
In mkdb/index.c:

#ifdef NEW_STYLE_BIN_SORT
#define SORT_COMMAND "sort -o %s -k 5,5 -k 4,4n -t : %s"
#else
#define SORT_COMMAND "sort -o %s +4 +3 -t : %s "
#endif

Just add before those lines:

#define NEW_STYLE_BIN_SORT

Run a

make clean && make && make install

Easily converting your .flac files to .mp3 format

flac2mp3 is a tool to convert potentially large sets of FLAC audio files into the MP3 audio format. It is implemented as a bash shell script, and should run on any Unix-like operating system.
You can get it at: bytemonkey.org
You'll have to install FLAC and LAME on your linux box, on debian/ubuntu this is easily done with

apt-get install lame flac

After you download flac2mp3 and untar it somewhere, run the script, feeding it with the source and destination directories:

/path/to/flac2mp3 /home/music/JimiHendrix_Experience/ /home/music/mp3/JimiHendrix_Experience/

Stresstesting IMAP clients

Just found an interesting article about IMAP clients comparison:
http://www.hackvalue.nl/en/article/64/stresstesting_imap_clients

Personally I'm using claws-mail, with 4 mail accounts, one of which has more than 250000 messages.

Migrating to it from thunderbird was fairly easy, I've converted my thunderbird filters to claws' format, using http://www.claws-mail.org/tools/claws-mail-thunderbird-filters-convertor.tar.gz
(See http://www.claws-mail.org/tools.php)
