Make a backup of the MIT-COOKIE auth file. Having this file will allow x11vnc to run without being root, eliminating much of the configuration headaches involved.

ps wwaux | grep auth

The file will be located in:

/var/run/xauth

In my case it was: /var/run/xauth/A:0-q6mb8o – but NOTE: This name will change frequently.  This is why we need to copy this out in the next step.

Create a new directory in ~/.vnc to store this file:

mkdir ~/.vnc

Copy the MIT-COOKIE file we found above to this location:

sudo cp /var/run/xauth/your_file ~/.vnc

Now install x11vnc:

sudo apt-get install x11vnc

Create a password:

x11vnc -storepasswd YOUR_PWD ~/.vnc/x11vnc.pass

Run x11vnc once:

x11vnc -forever -rfbport 5900 -rfbauth ~/.vnc/x11vnc.pass -o ~/.vnc/x11vnc.log -auth ~/.vnc/your_auth_file -noxdamage -display :0

The -auth switch points to the MIT-cookie auth file, and -noxdamage prevents Compiz from creating additional display issues. I would suggest changing the RFB or listening port to a non-standard one for security reasons.

First need to get SDelete from microsoft and run it on the guest machine to zero out the free space on the drive.

Grab SDelete from

http://www.microsoft.com/technet/sysinternals/Security/SDelete.mspx

Extract it, run it within the guest OS with -c :

sdelete -c c:

and shutdown the guest OS and virtualbox
then on the host (running ubuntu of course):

vditool SHRINK ntfs.vdi

BleachBit – Clean junk to free disk space and to maintain privacy

Catch And Convert – Download and convert video from websites

DropBox – Online Backup

FreeRapid Downloader – A simple Java downloader for downloading from file-sharing services

]]> http://blog.itchy.net/2010/09/useful-programs/feed/ 0 http://blog.itchy.net/2010/09/nagios-comments/ http://blog.itchy.net/2010/09/nagios-comments/#comments Thu, 23 Sep 2010 00:02:14 +0000 Brian http://blog.itchy.net/?p=281 Continue reading →]]> Comments are stored in /usr/local/nagios/var/status.dat

You can view it (non-intrusively) by doing cat /usr/local/nagios/var/status.dat

An example of one of the comment entries is:

hostcomment {
host_name=Customer ABC
entry_type=4
comment_id=27065
source=0
persistent=0
entry_time=1283883777
expires=0
expire_time=0
author=Nagios Admin
comment_data=Checking now (Rich)
}

Before you get too excited it’s not as easy as just editing that file.  This file is locked while nagios is running so you can’t edit anything.
If you stop nagios, however, the contents of status.dat are written to:
/usr/local/nagios/var/retention.dat

And this is where you can have fun!

While nagios is stopped you can edit the data in retention.dat, but I would recommend only using the following to avoid causing ownership problems:

/usr/local/nagios/var$ sudo -u nagios pico retention.dat

or

/usr/local/nagios/var$ sudo -u nagios gedit retention.dat

should also work but i don’t have a GUI on my servers here at home so can’t test it.

The key is the name.  You can move a comment to another entry by just changing the ‘host_name’ to another valid host.

It appears on each start of nagios any comments with invalid hosts are deleted.   So the only way you could change a hostname and retain comments would be to stop nagios – change the host-name in customers.cfg and then also find and replace in retention.dat for the same hostname-change.  And restart nagios.  (Remember to make sure you don’t fudge up the ownership/permissions)

If you just change the hostname in customers.cfg and restart nagios all old comments are wiped.

Other thoughts:

Entry Type:

entry_type=1 = User Comment
entry_type=2 = System Comments (flapping)
entry_type=4 = Acknowledgements

Fun with linux:

• if you wanted to see just the user comments for hosts:
  grep -B2 -A9 entry_type.1 retention.dat
• if you wanted to find all comments that contain Flubber you first search for retention (and get the 2 lines before and 9 lines after) then grep THOSE results for Flubber (-i = not-case-sensitive):
  grep -B2 -A9 entry_type.1 retention.dat | grep -B1 -A10 -i Flubber
• To replace the text ‘John’ with ‘John Doe’ you could:
  • cat retention.dat | sed “s/John/John Doe/g” >retention1.dat
    • the changed file will be at retention1.dat
  • To do it inline:
    • sed -i “s/John/John Doe/g” retention.dat

To fix it I had to add 3 options to the /etc/samba/smb.conf file and restart samba.

Below is the global section of smb.conf with the three additions I did highlighted.

[global]
log file = /var/log/samba/log.%m
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
obey pam restrictions = yes
null passwords = yes
map to guest = bad user
encrypt passwords = true
passwd program = /usr/bin/passwd %u
passdb backend = tdbsam
dns proxy = no
server string = %h server (Samba, Ubuntu)
unix password sync = yes
workgroup = WORKGROUP
syslog = 0
panic action = /usr/share/samba/panic-action %d
usershare allow guests = yes
max log size = 1000
pam password change = yes
follow symlinks = yes
wide links = yes
unix extensions = no

## Browsing/Identification ###

The three options I (well JD figured it out) added are the last three options:

follow symlinks = yes
wide links = yes
unix extensions = no

First install tightvncserver:

sudo apt-get install tightvncserver

Create script to start service:

To create the service-start script:

sudo pico /etc/init.d/vncserver

Paste in the below, modifying the variables at the top as necessary:

#!/bin/sh -e
### BEGIN INIT INFO
# Provides: vncserver
# Required-Start: networking
# Default-Start: S
# Default-Stop: 0 6
### END INIT INFO
PATH=”$PATH:/usr/X11R6/bin/”
# The Username:Group that will run VNC
export USER=”brian”
#${RUNAS}
# The display that VNC will use
DISPLAY=”1″
# Color depth (between 8 and 32)
DEPTH=”16″
# The Desktop geometry to use.
#GEOMETRY=”x”
#GEOMETRY=”800×600″
#GEOMETRY=”1024×768″
#GEOMETRY=”1280×1024″

#GEOMETRY=”1440×900″
# The name that the VNC Desktop will have.
NAME=”my-vnc-server”
OPTIONS=”-name ${NAME} -depth ${DEPTH} -geometry ${GEOMETRY} :${DISPLAY}”
. /lib/lsb/init-functions
case “$1″ in
start)
log_action_begin_msg “Starting vncserver for user ‘${USER}’ on localhost:${DISPLAY}”
su ${USER} -c “/usr/bin/vncserver ${OPTIONS}”
;;
stop)
log_action_begin_msg “Stoping vncserver for user ‘${USER}’ on localhost:${DISPLAY}”
su ${USER} -c “/usr/bin/vncserver -kill :${DISPLAY}”
;;
restart)
$0 stop
$0 start
;;
esac
exit 0

Finally, make the file executable:

sudo chmod +x /etc/init.d/vncserver

I found this elsewhere, thought it was hilarious, the pic takes you to where i found it.

Step One:

Ensure mencoder is installed, final processing step does require the use of a windows app using wine, so make sure both are installed.

sudo apt-get install mencoder wine unzip

Step Two:

Grab the freeware AVI-MUX program:  Website Link,  or use the code below.

Extract the zip to your windows ‘program files’ directory as configured in wine.  If you haven’t done any customization it is located at: “~/.wine/drive_c/Program Files”
I downloaded the zip to this location and extracted it at this location.

Accomplish all of this with:

cd ~/.wine/drive_c/Program\ Files

wget http://www.alexander-noe.com/video/amg/AVI-Mux_GUI-1.17.8.zip

unzip AVI-Mux_GUI-1.17.8.zip -d AVI-Mux_GUI-1.17.8

Step Three:

Save the script (At the bottom) into a location that is in your path and set as executable.  I kept the original authors name ‘pvc.sh’

Step Four:

Execute the conversion with:

./pvc.sh input_video.mkv output_name.avi

The Script:

Thomas (the script author) posted his script at the following location for download.

You can download ewelot’s script, and verify file integrity by running

md5sum pvc.sh

which must print the following hash value:

d9b3efdec6a32f1853f59784101d8503  pvc.sh

or copy the script below into a file into your path:

#! /bin/bash

############################################################################
#   pvc.sh [-hvdo] [-x|y] [-p player] [-c codec] [-b vbit] [-a abit]
#          [-k keyint] [-s start] [-l length]
  

#
#   Portable media player video converter for linux.
#
#   The purpose of this script is to convert videos into a format which
#   can be played by portable media players, e.g. the SanDisk Sansa Fuze.
#   It is based on mencoder and AVI-Mux_GUI.exe (under wine). The latter
#   can be found at: http://www.alexander-noe.com/video/amg
#
#   Examples:
#   - convert a video file for the Fuze:
#         pvc.sh anyvideo.mkv file.avi
#   - convert chapters 3 to 5 of title 2 from an anamorpic widescreen DVD:
#         pvc.sh -x dvd://2:3-5 dvdchapter.avi
#
#   Notes:
#   - You can reference selected chapters of DVD titles as
 by using
#     a special syntax of the form 'dvd://title:chapters' e.g. 'dvd://1:4-5'.
#     For a full list of other supported video input sources
#     (like streams e.c.) consult the manpage of mplayer/mencoder
#   - Temporary disk space of about the size of the output file is needed
#     under /tmp.
#   - Seeking ("-s start") is not supported by all
 types.
#   - There are rare cases where avimux-gui cannot handle AVI files
#     created by mencoder.

Mine worked fine, but his was acting very flakey.  It refused to see any music in sub-folders.  If you copied music into the root of the Music share it would see the songs, but it would freeze as soon as it started playing. Both devices successfully had taken the update to the latest firmware.

I had changed the USB settings on my device to ‘MSC’ mode, to prevent ubuntu from thinking it was a camera and allowed me to work with the files in a more pleasant view.  In this ‘MSC’ view I saw 5 files in the root of the device including 4 .sys files and a .sdk file.

Just on a wild hunch i copied the .sys files from the working device, to the flakey device and this corrected all issues. Both are now working great, playing all music files and properly seeing sub-folders.

SNMPD is the service running SNMP on a managed entity. SNMP comes in 3 versions. Version 1, the one we are going to use here is not secured, therefore we are going to make sure that only localhost is going to be able to access it.

People opening the service to the outside should make sure that trusted hosts can access the service either though the use of iptables or through the use of /etc/hosts.allow.
