Moving/Copying your PGP Keys

Once you’re using PGP, you may want be able to sign email from more than location, or you may switch computers. There’s a few ways to accomplish this.

Copy All GnuPG Data

Your first choice is to copy all of your GnuPG data. This is a lot more data than just your key, but is still likely to be under 5MB. This method will copy all of your keys, everyone’s key you have, and your entire trust database. It’s ideal for backup, or for moving to a new computer. Simply copy all the contents of your GnuPG data directory, which would be as follows:

  • Windows: C:/Documents and Settings/username/application Data/GnuPG
  • Unix/Linux/Mac: ~/.gnupg

Where username is your windows username. Just simply copy the entire contents of that directory from one machine to the other and you will be set. There are many ways to move this data, which I won’t cover. Some examples might be zipping the data up and copying it to a disk.

This will also work between different operating systems.

Configuring Syncthing in Windows, Linux, and on a Synology NAS

Syncthing is a useful open source tool to keep all of your files in sync over multiple computers. It works like Dropbox, but it’s a peer-to-peer system instead of having a central repository to host all of your files.

Windows Set Up

  1. Download the windows client from the Syncthing website.
  2. Copy the EXE file to a folder on your Windows machine.
  3. Create a Batch file in the same folder with the following:
    • start “Syncthing” syncthing.exe -no-console -no-browser
  4. Create a shortcut to the batch file and copy it to the startup folder. The startup folder can be accessed by entering “shell:startup” in the run dialog box.
  5. Admin interface is located at http://127.0.0.1:8384.

Update: SyncTrazor is a small stand-alone browser that automatically runs, restarts, updates etc. Syncthing for you.

Raspberry Pi as Eye-Fi Server

February 26, 2016

Raspberry Pi as Eye-Fi Server

At the time of this writing, there still isn’t an eyefiserver package in the stable Debian repository.  Sure, I could have enabled the testing repository and added the package that way, but since the installation only consists of adding a few files in certain locations, I’ll document the steps that I took:

First, grab the source eyefiserver off of the Debian web site: Continue reading

Setting Up MythTV in Debian 8 (or Armbian Jessie)

  • Boot Debian 8 Network Install CD (or Armbian Jessie image. If running Armbian with a USB harddrive, now would be a good time to run ‘nand-sata-install’ to boot off the HDD.)
  • Select “Install”.
  • Create “myth” user.
  • Choose separate “home” partition.
  • When prompted for software packages to install, unselect everything except “SSH Server” and “Standard System Utilities”.
  • Log in as “root” and run “apt-get install sudo”.  Then add “myth    ALL=(ALL:ALL) ALL” to /etc/sudoers & log out.
  • Log in as “myth” and add the following to /etc/apt/sources.list:
    • #deb-multimedia
    • deb http://deb-multimedia.org/ jessie main non-free
  • Add the following to /etc/apt/sources.list.d/webmin.list:
    • deb http://download.webmin.com/download/repository sarge contrib
  • Create the following directories:
    • mkdir /home/myth/recordings
    • chmod -R 777 /home/myth/recordings
    • mkdir /home/myth/recordings/banners
    • mkdir /home/myth/recordings/fanart
    • mkdir /home/myth/recordings/coverart
  • Run the following commands:
    • wget http://www.webmin.com/jcameron-key.asc
    • sudo apt-key add jcameron-key.asc
    • sudo apt-get update
    • sudo apt-get install deb-multimedia-keyring
    • sudo apt-get update
    • sudo apt-get upgrade
    • sudo apt-get install xauth webmin

      (Set Time Zone in Webmin. Time server is pool.ntp.org.)
    • sudo apt-get install mythtv mythweb
    • sudo service ntp start
    • wget https://github.com/MythTV/mythtv/raw/master/mythtv/programs/scripts/database/mythconverg_restore.pl
    • chmod a+x mythconverg_restore.pl
      (Use Webmin to copy MythTV database backup to root folder)
    • ./mythconverg_restore.pl –drop_database –create_database –directory /home/myth –filename mythconverg-1317-20170223222314.sql.gz
  • Edit /etc/php5/apache2/php.ini to fix a bug in mythweb:
    • max_input_vars = 100000
  • Add the IP address of the computer to /etc/mysql/my.cnf:
    • bind-address = 10.0.1.10
  • Restart Apache and MySQL. Also, start Myth Backend and run mythtv-setup from a remote computer:
    • sudo service apache2 restart
    • sudo service mysql restart
    • sudo service mythtv-backend start
    • (from remote computer) ssh myth@10.0.1.10 -X
    • (from remote computer) sudo nano /etc/mythtv/config.xml (copy database password)
    • (from remote computer) mythtv-setup (change the IP address to the IP address running MythTV and paste the database password).  You should now be able to finish setting up MythTV.

Asterisk 10 (1.10) SMS (messaging or SIP Messaging) in action

[UPDATE: WORKS FLAWLESSLY WITH ASTERISK 11 TOO…On Asterisk 11, you can choose XMPP as well as the protocol, right now its just SIP:, imagine the possibilities. Also fixed the issue when failed message]

[ANOTHER UPDATE FOR Offline message – We all know when devices are offline, messages cannot be sent and it will be discarded by Asterisk. I’ve written another dialplan/solution to that here]

With Asterisk 10 comes a channel independent dialplan for handling SIP MESSAGING (and jabber if that’s configured) method. In other words, phones that support SIP Continue reading

Debian Squeeze on a SheevaPlug

Setup

The process is fairly straight forward, but there are some requirements:

  • A TFTP server with some specific files. These should all be in the root of the TFTP directory.
  • The latest version of the SheevaPlug U-Boot binary.
  • The latest version of the Debian installer image (uImage and uInitrd).
  • The latest version of the Linux kernel (optimized for SheevaPlug; uImage and Modules).
  • A 2+ GB USB thumb drive.
  • Terminal emulation software (GNU screen, PuTTY, minicom, HyperTerm) [Note: Mac OS X’s version of screen seems to have issues with the debian installer, so I used PuTTY in a VM.]
