apt-get install xinetd libc6-i386
wget http://ftp.acc.umu.se/mirror/ubuntu/pool/universe/g/gcc-2.95/libstdc++2.10-glibc2.2_2.95.4-24_i386.deb
sudo dpkg --force-architecture -i libstdc++2.10-glibc2.2_2.95.4-24_i386.deb

after that, in your NetBackup Client directory, edit:

NBClients/anb/Clients/usr/openv/netbackup/client/Linux/RedHat2.4/cp_to_client

and look for /etc/rc.d/init.d/xinetd and remove the “rc.d/” from the path.

./install

and you’re good to go.
if you have any patches, create a directory and put the patches in there, decompress and install:

mkdir patches
mv NB_* patches
cd patches
tar xvf NB_CLT_60_6_M_XXXXXX.tar
tar xvf NB_JAV_60_6_M_XXXXXX.tar
./Vrts_pack.install

Edit: Apparently there’s some problems with libgcc_s.so.1 (if you’re installing on a 64bit OS). Either it doesn’t find a suitable libgcc, or doesn’t find it at all. Same happens with libpam.so.0.

me@server:~# telnet localhost 13782
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
bpcd: error while loading shared libraries: libgcc_s.so.1: wrong ELF class: ELFCLASS64

me@server:~# telnet localhost 13782
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
bpcd: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory

Fear not. This is what you’re looking for:

sudo apt-get install lib32gcc1 ia32-libs
sudo ln -s /usr/lib32/libgcc_s.so.1  /usr/openv/lib/libgcc_s.so.1
sudo ln -s /lib32/libpam.so.0 /usr/openv/lib/libpam.so.0

it fails, you can try the fakeraid howto for < 8.10 versions, but your best shot is to use the 8.10 alternate install cd (only one that supports this feature).

It will prompt you to activate the embedded sata raid devices, which you’ll obviously do, the rest of the installation is the same as a regular install, minus the graphic mode.

Chances are that you won’t be able to boot after the installation and get a busybox shell prompt with an error message “Gave up waiting for root device”.

Check if this lets you continue with the boot sequence:

dmraid -ay
exit

if it does, you’ve hit the jackpot.

edit your /usr/share/initramfs-tools/scripts/local-top/dmraid to look like this:

#!/bin/sh

PREREQ="udev"

prereqs()
{
echo "$PREREQ"
}

case $1 in
# get pre-requisites
prereqs)
prereqs
exit 0
;;
esac

/sbin/udevadm settle --timeout=30
modprobe -Q dm-mod
modprobe -Q dm-mirror

[ -x /sbin/dmraid ] && /sbin/dmraid -ay

and execute as root:

update-initramfs -u

One of my prospect customers asked me if I could set up a RoR capable server for him, after some research this is what I came up with.

My distro of choice is ubuntu/debian, mainly cause that’s what I use to run this server.

First you need to install all the ruby goodies.

sudo apt-get install ruby rdoc irb libyaml-ruby libzlib-ruby \
 ri libopenssl-ruby

Ruby has its own package manager, which tends to work better than apt-get dependency wise. It’s called RubyGems, and you can grab it at rubyforge.org.

wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz
tar zxvf rubygems-1.3.1.tgz
cd rubygems-1.3.1
sudo ruby setup.rb

after it’s installed, you want to create a link to your executable and install rails using the gem tool.

sudo ln -s /usr/bin/gem1.8 /usr/bin/gem
sudo gem update --system
sudo gem install rails

Now you need to make a decision, mongrel or apache as the web server. I chose to stick with apache due to personal preference (more homogeneous environment to administer).

sudo gem install passenger
sudo apt-get install apache2 apache2-prefork-dev
sudo passenger-install-apache2-module

add this to your apache config (your versions may change, just grab the output from the passenger installer you’ve just executed).

   LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.0.3/ext/apache2/mod_passenger.so
   PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.0.3
   PassengerRuby /usr/bin/ruby1.8

and you’re good to go, don’t need to do any extra configuring, just your every day apache vhost mumbo jumbo.

However if you wanted to install mongrel instead:

sudo apt-get install build-essential ruby1.8-dev
sudo gem install mongrel

How well mongrel works, and what config does it need, I don’t know.

You will need some sort of database, SQLite or MySQL are good choices depending on the size of your project. SQLite is more of a get-me-started-quick-i-don’t-care-about-all-the-database-nonsense database, while MySQL will let you scale better, adapt and offer you different storage engines depending on your needs (transactional, clustered, memory only, archive, etc).

I’ve owned a ReadyNAS NV for quite a while now, I’ve always thought it was a great product.

After they allowed ssh access to the box (with raidiator 4.0) they made it even better. Low power consumption, debian linux, and a metric ton of diskspace make it a really hackable device.

It has a bittorrent client addon available, the problem is that it is only accessible via an http interface, and cannot import torrents automagically from a specified location like a drop-in folder or an rss feed, unlike some of my favorite torrent clients.

I did a bit of reading and put together a few pieces of script-fu that already existed on the internet.

Auto importing torrents from drop-in folder

First piece to the puzzle is chirpa’s auto-import script as it appeared in the readynas forums, with a tiny modification to fix the whitespace problem with torrent names.

You can see the original thread here:

http://www.readynas.com/forum/viewtopic.php?f=35&t=19126

#!/bin/sh
#     What: Import .torrents into the NETGEAR ReadyNAS BitTorrent
#              Download Manager
#      Who: Quickly slapped together by chirpa (readynas.com/forum)
#    Usage: Crontab it and walk away.
# Requires: Curl (maybe I'll make it work with Wget at some point)
#  Version: 0.2a
#     Todo: Check for returned status: apiTorrentAddFinishedOk /
#           apiTorrentAddFailed

INCOMING_DIR=/c/torrent
DONE_DIR=/c/torrent/done
BTURL="http://localhost:8080/api/torrent-add?start=yes"
ORIG_IFS=$IFS
IFS=$'\n'
cd $INCOMING_DIR
for f in `ls -1 *.torrent 2>/dev/null`
do
echo Loading file: $f
curl -s -F fileEl=@$f $BTURL >/dev/null
mv $f $DONE_DIR
done
IFS=$ORIG_IFS

You can name this file “import_torrents” and run it every N minutes, adding it to your crontab. I run mine every 5 minutes.

Auto downloading torrents from an RSS feed

Lets suppose we want to download torrents from a mininova.org feed, this script coded by Abhi Yerra will get you started.

Note you will need to install both the python and python-feedparser packages via apt-get and also, you will need to modify DownloadPath, DownloadLog and FeedUrl to fit your needs.

#!/usr/bin/python
import feedparser
import urllib2

DownloadPath = '/c/torrent/'
DownloadLog = '/c/torrent/.tvdownloads'
FeedUrl = 'http://www.mininova.org/rss.xml?cat=6'

def is_downloaded(link):
        return link in open(DownloadLog, 'r+').read()

def write_log(link):
        open(DownloadLog, 'a+').write('%s\n' % link)

def get_tvtorrents():
        parser = feedparser.parse(FeedUrl)
        for item in parser['items']:
                if not is_downloaded(item['link']):
                        torrentfile = DownloadPath + item['title'].replace(' ', '_') + '.torrent'
                        torrentdata = urllib2.urlopen(item['link']).read()
                        print "Writing to: %s" % torrentfile
                        open(torrentfile, 'wb').write(torrentdata)
                        write_log(item['link'])

if __name__=='__main__':
    get_tvtorrents()

Crontab it, every 10 minutes or so, and you’re dandy.

You can find the original script here:

http://abhiyerra.wordpress.com/2007/02/17/python-vs-ruby-for-a-simple-script/

You may or may not know about yahoo pipes, which is an awesome tool for processing all sorts of information from the interweb, especially rss feeds although it will work with other formats too. The posibilities are virtually limitless.

Enjoy!

more and better to follow soon.
