Due to the static nature of the pages for years i removed the pages on the flight simulation topic. You still can look into the @4ehamspotters pages.
I added a small howto to add a Maginon IPC-10AC camera (sold at Aldi) to Synology Surveillance station version 7.
I often use a proxy server over a SSH tunnel when i’m in public places. I found it sometimes annoying to click through the dialogs Controlpanel -> Network -> Advanced -> Proxies. I thought i would create a script which enables or disables the proxy settings for me for either the Ethernet or Wireless adapter on my macbook.
The shell scripts uses the commandline tool “networksetup” to alter the settings.
The “enable proxy” script: (this script also builds the tunnel to a proxy server over port 443)
#!/bin/sh echo "Connecting to , provide password for firstname.lastname@example.org if prompted" echo "Enabling proxy for HTTP (please provide admin password if prompted)" sudo networksetup -setwebproxystate Ethernet on sudo networksetup -setwebproxystate wi-fi on echo "Enabling proxy for HTTPS (please provide admin password if prompted)" sudo networksetup -setsecurewebproxystate Ethernet on sudo networksetup -setsecurewebproxystate wi-fi on ssh email@example.com -p443 -L3128:localhost:3128 -o TCPKeepAlive=yes -g exit
The “disable proxy” script:
#!/bin/sh echo "Disabling proxy for HTTP and HTTPS" sudo networksetup -setwebproxystate Ethernet off sudo networksetup -setsecurewebproxystate Ethernet off sudo networksetup -setwebproxystate wi-fi off sudo networksetup -setsecurewebproxystate wi-fi off echo "Done." exit
For a more secure terminal (SSH) environment, you can add a second factor to authenticate a user. I personally run Ubuntu and i implemented the Google Authenticator on my Ubuntu system using the Google Authenticator Library of Google in combination with my iPhone with the Google Authenticator App.
See the following howto:
Zabbix 1.8.6 has been released on August 4th. Within this relase several new features have been added and even more improvements are implemented:
Added ability to force configuration cache reload of a running server and proxy, which, in the case of active proxy, will also force config re-read from the server.
Zabbix will complain if there are unsupported attributes in server, proxy or agent configuration files.
It is safe to use Zabbix with the latest releases of PostgreSQL.
Added performance monitoring of LVM devices.

In some cases it may come in quite handy to empty your mail queue’s right away, this script which executes at your prompt clears (deltes) the messages which are in the queue.
Another small howto: rsync two (remote) folders
I’ve added another quick how to on how to hide your user input while asking for a password fromout Bash.
This is a quick howto to enable you to relay all your Postfix mailtraffic to either your ISP’s SMTP gateway or to forward your outgoing mail to a corporate centralized gateway. This can even be done on a non standard SMTP port.
