After the last power failure of our server I decided to work out how to make Irssi autoreconnect to the channels/servers of my choice. This was pretty easily done.

vim .irssi/config

#Here you define the servers you want to use
#Chatnet is just an alias, you can write whatever here
servers = (
{
        address = "irc.url.se";
        chatnet = "SOMEALIAS";
        port = "6667";
        password = "XXX";
        use_ssl = "no";
        ssl_verify = "no";
        autoconnect = "yes";
}
{
        address = "irc.url2.se";
        chatnet = "SOMEOTHERALIAS";
        port = "6667";
        use_ssl = "no";
        ssl_verify = "no";
        autoconnect = "yes";
}
);

chatnets = {
        SOMEALIAS = { type = "IRC"; };
        SOMEOTHERALIAS = { type = "IRC"; };
};

channels = (
        { name = "#CHANNELNAMEHERE"; chatnet = "SOMEALIAS"; autojoin = "yes"; },
        { name = "#CHANNELNAMEHERE"; chatnet = "SOMEOTHERALIAS"; autojoin = "yes"; },
);
#THIS SECTIONS DEALS WITH YOUR CHANNELS.  THE NUMBER IS THE WINDOW NUMBER
#A CHANNEL WILL APPEAR IN.
windows = {
  1 = { immortal = "yes"; name = "(status)"; level = "ALL"; };
  2 = {
    items = (
      {
        type = "CHANNEL";
        chat_type = "IRC";
        name = "#CHANNELNAMEHERE";
        tag = "SOMEALIAS";
      }
    );
  };
  3 = {
    items = (
      {
        type = "CHANNEL";
        chat_type = "IRC";
        name = "#CHANNELNAMEHERE";
        tag = "SOMEOTHERALIAS";
      }
    );
  };
};
mainwindows = { 1 = { first_line = "1"; lines = "22"; }; };

Great little command for finding weird includes.

#for example
apt-file search libgtk-x11-2.0.so

Decided to write down how I made the rewrite + ssl for an e-mail server. What I want to do is instead of getting to roundcube with http://hostname.se/webmail I only want to use webmail.hostname.se. Aswell I want it to go to HTTPS by itself.

This is tested and working on Ubuntu 10.04 and 10.10 server edition.

Here we go.

First create the certs and copy them to the necessary folders

sudo -s
openssl req -new -x509 -nodes -out /etc/ssl/certs/server.crt -keyout /etc/ssl/private/server.key
#OBS! Common name should be your servers hostname
a2enmod rewrite
a2enmod ssl
a2ensite default-ssl
chmod 400 /etc/ssl/private/server.key
#Rest will be done in the apache2 folder
cd /etc/apache2

ports.conf

NameVirtualHost *:80
Listen 80
<IfModule mod_ssl.c>
NameVirtualHost *:443
    Listen 443
</IfModule>

apache2.conf

#leave most as is, just add servername
#ServerRoot "/etc/apache2"
ServerName yourhostname

sites-available

touch sites-available/webmail
touch sites-available/webmail-ssl
cd sites-available

sites-available/webmail

<VirtualHost *:80>
        ServerAdmin user@hostname.se
        ServerName webmail.hostname.se
RewriteEngine   on
RewriteCond     %{SERVER_PORT} ^80$
RewriteRule     ^(.*)$ https://webmail.hostname.se$1 [L,R]
RewriteLog      "/var/log/apache2/rewrite.log"
RewriteLogLevel 2
</VirtualHost>

sites-available/webmail-ssl

<IfModule mod_ssl.c>
<VirtualHost *:443>
        ServerAdmin user@hostname.se
        Servername webmail.hostname.se
        DocumentRoot /var/lib/roundcube
    <Directory /var/lib/roundcube>
        Options -Indexes IncludesNOEXEC FollowSymLinks
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>
SSLEngine on
SSLCertificateFile /etc/ssl/certs/server.crt
SSLCertificateKeyFile /etc/ssl/private/server.key
BrowserMatch ".*MSIE.*" \
        nokeepalive ssl-unclean-shutdown \
        downgrade-1.0 force-response-1.0
</VirtualHost>
</IfModule>

Enabling the sites

a2ensite webmail
a2ensite webmail-ssl
#check that your sites is enabled
ls -l /etc/apache2/sites-enabled/
#output should be like this
000-default -> ../sites-available/default
default-ssl -> ../sites-available/default-ssl
webmail -> ../sites-available/webmail
webmail-ssl -> ../sites-available/webmail-ssl
#restart the webserver, all should be well
/etc/init.d/apache2 restart
#now test it out by entering webmail.url.com in a webbrowser

To get this to work you need a very old version of Ubuntu. These days I recommend Observium with Weathermap addon.

/V

First we download the programs and install the plugin structure:

sudo -s
mkdir cacti_weathermap
cd cacti_weathermap
apt-get install cacti-spine
wget http://mirror.cactiusers.org/downloads/plugins/cacti-plugin-0.8.7g-PA-v2.8.tar.gz
tar xvf cacti-plugin-0.8.7g-PA-v2.8.tar.gz
wget http://www.network-weathermap.com/files/php-weathermap-0.97a.zip
unzip php-weathermap-0.97a.zip
cd cacti-plugin-arch/files-0.8.7g
sudo cp -R * /usr/share/cacti/site/
cd ..
mysql cacti < pa.sql -u root -p
sudo vim /usr/share/cacti/site/include/global.php
#row 107:
$config["rra_path"] = $config["base_path"]."/rra";
#change it to:
$config["rra_path"] = '/var/lib/cacti/rra';
#row 197
include($config["library_path"]."/adodb/adodb.inc.php");
#change it to:
include("/usr/share/php/adodb/adodb.inc.php");
#row 100
$config['url_path'] = $url_path;
#change to
$config['url_path'] = '/cacti/';
#below row 42 $cacti_session_name = "Cacti"; add
/* Weathermap */
$plugins = array();
$plugins[] = 'monitor';
$plugins[] = 'weathermap';
#save and quit
sudo chmod 644 /usr/share/cacti/site/lib/plugins.php
sudo chmod 644 /usr/share/cacti/site/include/plugins.php

Source: http://58.96.99.76/joomla/index.php/tech-a-it-stuff/networking-other/66-cacti-plugin-architecture-install-on-ubuntu

Then we install weathermap:

cd ..
mv weathermap/ /usr/share/cacti/site/plugins
chown -R www-data:www-data /usr/share/cacti/site/plugins

#http://url.to.host/cacti/index.php should greet you with http://url.to.host/cacti/install.php. Just press next etc and all should be well.

Now login and set the permissions for your user

mv /usr/share/cacti/site/plugins/weathermap/editor-config.php-dist /usr/share/cacti/site/plugins/weathermap/editor-config.php
chmod u+w /usr/share/cacti/site/plugins/weathermap/configs
#Now we need to secure the editor
vim /etc/apache2/conf.d/weathermap
<Directory /usr/share/cacti/site/plugins/weathermap>
        <Files editor.php>
            Order Deny,Allow
            Deny from all
            Allow from 127.0.0.1
        </Files>
    </Directory>
/etc/init.d/apache2 restart
vim /usr/share/cacti/site/plugins/weathermap/editor.php
#change
$ENABLED=false;
#to
$ENABLED=true;
#change
$cacti_base = 'C:/httpd-.2_x64/htdocs/cacti';
#to
$cacti_base = '/usr/share/cacti/site';
#change
$cacti_url = "http://support.company.net/cacti/";
#to
$cacti_url = "http://url.to.host/cacti/";

Tips:
After the installation of everything you might need to go into Cacti and set Spine as poller again.

Here is how my rudimentary homenetwork looks like (I just used icons that are included, you can use your own pictures).

I’ve removed the other guide, easier to maintain one guide. This server will allow relay for specified nets and also TLS encrypted login for users.

Highlighted rows is where you need to make your personalized changes.

Passwords are finally encrypted and working. Thanks to No1Viking @ this thread Ubuntu.se

Update for Ubuntu 11.10 (Dovecot wasn’t working):

Begin with generating a new dovecot.conf from your old one with:

cd /etc/dovecot
doveconf -n > dovecot-new.conf
mv dovecot.conf dovecot.conf_old
mv dovecot-new.conf dovecot.conf
#Then edit the dovecot.conf and search for service auth {
#Comment out this row
#       user = nobody
/etc/init.d/dovecot restart
#Now dovecot should restart and work.

These are the programs I used to do it:
Amavis, Dovecot, SpamAssassin, Clamav, Postfixadmin, Postfix, Mailgraph and Roundcube for webmail.

Install the necessary packages

sudo -s
apt-get install dovecot-common dovecot-imapd dovecot-pop3d postfix postfix-mysql mysql-server spamassassin clamav mailgraph roundcube roundcube-mysql amavisd-new php5-imap clamav-daemon
#Choose Internetsystem when postfix asks.
#Allow roundcube to setup the database with db-common.

Setting up

Create the necessary folders, user and permission

useradd -r -u 150 -g mail -d /var/vmail -s /sbin/nologin -c "Virtual mailbox" vmail
sudo mkdir /var/vmail
sudo chmod 770 /var/vmail/
sudo chown -R vmail:mail /var/vmail/
sudo mysql -u root -p
CREATE DATABASE mail;
GRANT ALL PRIVILEGES ON mail.* TO 'mail'@'localhost' IDENTIFIED BY 'mail';
exit

Postfixadmin

Download and install postfixadmin, it should ask for the database to use and setup the necessary tables.

http://downloads.sourceforge.net/project/postfixadmin/postfixadmin/postfixadmin-2.3.2/postfixadmin-2.3.2_all.deb?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fpostfixadmin%2Ffiles%2F&ts=1283411400&use_mirror=cdnetworks-us-1
dpkg -i postfixadmin_2.3.2_all.deb
vim /etc/apache2/conf.d/postfixadmin
#replace all with
Alias /postfixadmin /usr/share/postfixadmin
 <Directory /usr/share/postfixadmin>
  Options FollowSymLinks Indexes
  AllowOverride Limit Options FileInfo
  <Limit GET POST>
        order deny,allow
        deny from all
        allow from ip.to.host.X
        allow from range.if.youlike.0/24
  </Limit>
</Directory>

I’m pretty sure postfixadmin installs it’s database to “postfixadmin”. This will not work in our example. It’s very easy to fix that though.

vim /etc/postfixadmin/config.inc.php
#change lines 50-54 to these
$CONF['database_type'] = 'mysqli';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'mail';
$CONF['database_password'] = 'mail';
$CONF['database_name'] = 'mail';
#now we also need to run http://url.to.host/postfixadmin/setup.php and check so all goes well. Then choose a superadmin password so you get the hash.
#Then change row 31 to the hash 
$CONF['setup_password'] = 'false'; #change this to the hash row
#also you might to want to change
$CONF['admin_email'] = 'admin@your.host.com';
$CONF['encrypt'] = 'md5crypt'
$CONF['authlib_default_flavor'] = 'md5raw';
#check the file, there is alot of easy options to choose and change

Roundcube

/etc/roundcube/main.inc.php

change these lines:
$rcmail_config['default_host'] = 'ssl://localhost:993';
$rcmail_config['default_port'] = 143;
$rcmail_config['auto_create_user'] = TRUE;
$rcmail_config['imap_auth_type'] = auth;
$rcmail_config['smtp_server'] = 'localhost';
$rcmail_config['smtp_port'] = 25;
$rcmail_config['smtp_helo_host'] = 'host.name.com';
$rcmail_config['date_long'] = 'Y.m.d H:i';
$rcmail_config['product_name'] = 'My Webmail';
$rcmail_config['create_default_folders'] = TRUE;
also fix roundcube in apache
#uncomment

  allow from range.if.youlike.0/24
</Directory>

Misc fixes

Now we’re almost done, just need to create the aliases

vim /var/vmail/local_domains
#insert the name of your domain.
cp /etc/aliases /etc/postfix/aliases
#or just create it, seems to be the same for most
vim /etc/postfix/aliases
# /etc/aliases
mailer-daemon: postmaster
postmaster: root
nobody: root
hostmaster: root
usenet: root
news: root
webmaster: root
www: root
ftp: root
abuse: root
noc: root
security: root
root: (yourusername)
clamav: root
#Now we need to create the aliases.db file. It's done with the postalias command.
postalias /etc/postfix/aliases

Restart everything!

/etc/init.d/clamav-daemon restart
/etc/init.d/clamav-freshclam restart
/etc/init.d/dovecot restart
/etc/init.d/postfix restart
/etc/init.d/apache2 restart

Add accounts and test webmail

Login to postfixadmin with http://url/postfixadmin. Here you can add your e-mail accounts, do this before trying to login to roundcube 🙂
After that login to roundcube, http://url/roundcube
If you experience any problems, check /var/log/mail.log

Sources

Most of this material is taken from other webpages which also contains great guides (will list more as I recall them):

• Postfix guide
• Ubuntu community Postix guide

This is the easiest way I know how to SSH/SCP between hosts without using passwords. When using ssh-keygen just hammer enter, we want a key without password for this to work.

ssh-keygen
ssh-copy-id -i .ssh/id_rsa.pub backupuser@ip.to.host
#Test it out by invoking
ssh backupuser@ip.to.host

You should have gotten in without password. This can then be used to for instance backup from one machine to another easily (without using Bacula). Yes, I know it’s quick and dirty but until I understand Bacula this is the way to do it 🙂
So I created this bash script for my e-mail server backup (thanks vho for the mysqldump script!). I placed the file in /root/ and called it backup.sh
(As you can see I compress a folder called IP_TO_FTP_SERVER, this is a folder created by wget from a local FTP running FileZilla server. This is because it’s running Windows XP and a Swedish billing system called Scrollan.)

Backup.sh

scp $backupDir/$time* backupuser@url.to.host:$backupDir

Don’t forget to make the script runnable by chmod +x /root/backup.sh
Then I made the folder /home/backup and added the work to run in cron.

mkdir /home/backup
crontab -e
00 04 * * * /root/backup.sh

Now on the backupservers I’ve done like this (user backup already exists on Ubuntu)

adduser backupuser
mkdir -p /home/backup/hostname
chown -R backupuser:backupuser /home/backup

You should now get some backups, spread the backups around between different secure servers and your good to go when the next HDD crash arrives 🙂

This weekend I started having fun with moving my old HTPC from Windows to the Linux world. And I immediately started having problems. The problems is almost always the fun part with Linux though, it can be very frustrating at first but very rewarding when you solve them 🙂

Less chat, more explaining.

I chose Ubuntu after trying Xubuntu because it’s much easier to resize the menus/fonts in Ubuntu so I dont have to squint to read the text on my 40? LCD 1080p TV. But the downside is that Ubuntu provides alot of junk you don’t need.

I find pulseaudio still causing problems, so I just remove it.

sudo apt-get purge pulseaudio
#then reboot

After the reboot you only need to activate the Digital out. This is easily done with alsamixer.

sudo alsamixer

Then scroll right until you can see ie958 o and press m to unmute it (MM is mute) so it says 00?. Now the digital out should work.

Now to install XBMC:

sudo add-apt-repository ppa:team-xbmc
sudo apt-get update
sudo apt-get install xbmc xbmc-standalone

If you are running XBMC on lower end hardware you might want to skip logging in to Gnome. To do this just logout and press the name for your user. Before you login change the session to XBMC in the bottom of the screen and login. This way you only login to XBMC.

Have fun! Dont forget to add ie958 in sound output settings in XBMC!

Microsoft Remote

This is how I made my MCE work with Ubuntu 10.04.1 and XBMC (doesn’t work with 10.10)

sudo apt-get install lirc
#select antec veris on first screen and use default (none on second)
vim /etc/udev/rules.d/99-lirc.rules
#add this
#Prevent the USBHID driver from loading for the Antec Veris
SYSFS{idVendor}=="15c2", SYSFS{idProduct}=="0038", MODE="0666", PROGRAM="/bin/sh -c 'echo -n $id:1.0 >/sys/bus/usb/drivers/usbhid/unbind;\
echo -n $id:1.1 >/sys/bus/usb/drivers/usbhid/unbind'"
#then reboot the HTPC
vim /etc/modprobe.d/lirc_imon.conf
#add this
options lirc_imon ir_protocol=1
vim /etc/lirc/hardware.conf
#change REMOTE_LIRCD_CONF="imon/lircd.conf.imon-antec-veris" to REMOTE_LIRCD_CONF="imon/lircd.conf.imon-mceusb"
vim /etc/lirc/lircd.conf
#Change include "/usr/share/lirc/remotes/imon/lircd.conf.imon-antec-veris" to include "/usr/share/lirc/remotes/imon/lircd.conf.imon-mceusb"
#now restart lirc
/etc/init.d/lirc restart
#try the remote out with irw and push some buttons, you should get output in a terminal window.
#to get the remove to work optimally for XBMC use this lircmap
sudo wget -q http://www.stpit.com/public/Lircmap.xml -O ~/.xbmc/userdata/Lircmap.xml
#now reboot for the modprobe to accept the new values

Credit for lircmap and how-to for MCE goes to stpfarms@forums.xbmc.org

You can try the remote out with the command irw and then just press buttons on it and should get an output. Like this:

Dont forget to activate web server and LCD in XBMC, user XBMC, no password, 8080 as port.

In 11.10+ it’s pretty easy to use rTorrent. We don’t need to download and compile rTorrent anymore, apt-get works just fine.

sudo apt-get install rtorrent libapache2-mod-scgi

Now to make the .rtorrent.rc file which should be in the home folder of the user running rtorrent (/home/usernameofyouruser/.rtorrent.rc). In my example I have my download folder as /home/user/nedladdat/torrents/downloads.

# Maximum and minimum number of peers to connect to per torrent.
min_peers = 40
max_peers = 120
# Same as above but for seeding completed torrents (-1 = same as  downloading)
min_peers_seed = 10
max_peers_seed = 50
# Maximum number of simultanious uploads per torrent.
max_uploads = 20
# Global upload and download rate in KiB. "0" for unlimited.
download_rate = 0
upload_rate = 0
# Default directory to save the downloaded torrents.
directory = ~/nedladdat/torrents/downloads
# Default session directory.
session = ~/nedladdat/torrents/rtorrent.session
# Watch a directory for new torrents, restart torrents that have been  copied back and stop those that have been
# deleted.
schedule =  watch_directory,10,10,"load_start=~/nedladdat/torrents/torrentfiles/*.torrent"
schedule = tied_directory,10,10,start_tied=
schedule = untied_directory,10,10,close_untied=
# Close torrents when diskspace is low.
schedule = low_diskspace,5,60,close_low_diskspace=100M
#Stop torrents when reaching upload ratio 300 percent
ratio.enable=
ratio.min.set=300
# Port range to use for listening.
port_range = 6890-6999
# Start opening ports at a random position within the port range.
port_random = yes
# Set whetever the client should try to connect to UDP trackers.
use_udp_trackers = yes
# Encryption options. This can be useful when using an ISP that uses  traffic shaping.
encryption=allow_incoming,try_outgoing,enable_retry,prefer_plaintext
scgi_port = 127.0.0.1:5000
xmlrpc_dialect=i8
#DHT
dht = auto
dht_port = 6881
peer_exchange = yes

You also need to activate scgi support in Apache 2:

sudo a2enmod scgi

Next you need to add the SCGI mount for rTorrent.

sudo vim /etc/apache2/sites-available/default
#And add the following lines at the near-end of the document:
    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options -Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>
SCGIMount /RPC2 127.0.0.1:5000
<location /RPC2>
        <Limit GET POST>
        order deny,allow
        deny from all
        allow from 127.0.0.1
        allow from 192.168.1.254
        allow from 192.168.1.0/24
        </Limit>
</location>
</VirtualHost>

And restart Apache 2:

sudo /etc/init.d/apache2 restart

You are now done with rTorrent, try if it works by logging in the correct user and executing rtorrent. When you see it starts and that you can download for example Ubuntu via torrent then all is fine. You might as “but how do I start the download”, well that’s easy, just place the ubuntu.rtorrent file in /home/user/nedladdat/torrents/torrentfiles (as by my example) and rTorrent should start it by itself.

Now to get a nice GUI for rTorrent we need to download ruTorrent and move this folder to /var/www

wget http://rutorrent.googlecode.com/files/rutorrent-3.4.tar.gz
tar xvzf rutorrent-3.4.tar.gz
mv rutorrent /var/www/rtorrent

You need to change the ownership of the directory of rtorrent in /var/www to www-data.

chown -R www-data:www-data /var/www/rtorrent

Now you can login to http://yourip/rtorrent

Enjoy!

A friend of mine said to me: I want a torrent client which will download, then unpack and when I remove the torrent or seed is done it will remove the rar files and keep the rest.

EDIT (2010-08-31): This guide is mostly obsolete now as you can easily just download the plugin unpack to the plugin folder where your rutorrent is installed (v.3.1 required) and it will unpack the files for you.

First you need to download the necessary applications

sudo apt-get install unzip unrar

So, to get your rTorrent to unpack the files on download and delete on
ratio/delete of torrent file you need to modify your .rtorrent.rc file
with these changes:

# Maximum and minimum number of peers to connect to per torrent.
#min_peers = 40
#max_peers = 100

# Same as above but for seeding completed torrents (-1 = same as downloading)
#min_peers_seed = 10
#max_peers_seed = 55
#max_downloads_global = 3
#max_uploads_global = 5

# Maximum number of simultanious uploads per torrent.
#max_uploads = 15

# Global upload and download rate in KiB. "0" for unlimited.
#download_rate = 3000
#upload_rate = 3000

# Default directory to save the downloaded torrents.
directory = /home/user/nedladdat/torrents/downloads

# Default session directory.
session = /home/user/nedladdat/torrents/rtorrent.session

# Watch a directory for new torrents, restart torrents that have been copied back and stop those that have been
# deleted.
schedule = watch_directory,10,10,"load_start=/home/user/nedladdat/torrents/torrentfiles/*.torrent"
schedule = tied_directory,10,10,start_tied=
schedule = untied_directory,10,10,close_untied=

#Extract rar/zip/001 files when download is complete
system.method.set_key = event.download.finished,unpack_rar,"execute=/home/user/rtorrent/unpack_files.sh,$d.get_base_path="

#Delete rar/zip/001 files when share is complete or torrent file is erased
system.method.set_key = event.download.erased,rm_files,"execute=/home/user/rtorrent/delete_files.sh,$d.get_base_path="

# Close torrents when diskspace is low.
schedule = low_diskspace,5,60,close_low_diskspace=1000M

#Stop torrents when reaching upload ratio 300 percent
ratio.enable=
ratio.min.set=300

# Port range to use for listening.
port_range = 6890-6890

# Start opening ports at a random position within the port range.
#port_random = yes

# Set whetever the client should try to connect to UDP trackers.
use_udp_trackers = yes
check_hash = no
hash_read_ahead = 8
hash_interval = 10
hash_max_tries = 5

#max_open_sockets = 32768
#send_buffer_size = 65536
#receive_buffer_size = 65536
max_open_files = 128

# Encryption options. This can be useful when using an ISP that uses traffic shaping.
encryption=allow_incoming,enable_retry,prefer_plaintext
scgi_port = 127.0.0.1:5000
xmlrpc_dialect=i8

#DHT
dht = auto
dht_port = 6881
peer_exchange = yes

Then you need to create the two scripts and chmod +x them so they are runnable.

unpack_files.sh

#!/bin/bash

        #Create only 1 instance of this script to avoid rTorrent crashing

                                rarFile=`ls $directory | fgrep -i .rar | head -n 1`;

As you can see the two scripts are very similar. The first two checks were necessary because rTorrent freaks out when the script takes too long to complete and starts it again and again in an eternal loop 🙂

So first the scripts checks am I in the right download folder, in this case /nedladdat/torrents/ if so then it checks have I already been started? if not it makes a pidfile then it uses find to loop all folders and subfolders it can find and unpack rar/zip/001 files.
