thompson router with

I need to create a dynamic dns rule in a thompson technicolor router. Problem is the ‘custom’ dns settings don’t let you actually change their default dns server. people have found they can telnet into the router and change the settings at the command line: see here

1. Telnet to the router IP address (normally

2. Log into the router using appropriate login details (if unknown, try Username: Administrator, and no password)

3. List the current Dynamic DNS options
dyndns service list

4. Modify the custom option using this command:
dyndns service modify name=custom port=www-http request=/nic/update updateinterval=7200

Replace values appropriately
server – the domain name of your Dynamic DNS provider
port – www-http
request – /nic/update [the path at your Dynamic DNS provider for DNS update calls]
updateinterval – number of seconds between updates from your router – default is 86000 (1 day)

5. Save changes to the router

streaming test

This is a test to tryout our streaming server and see if the embdded player will work OK.
If you are a tester let me know!

remote vnc desktop

It’s not as easy as you might think to setup a remote desktop from boot in Xubuntu.

This is probably because these apps are called ‘desktop sharing’ apps, really aimed at desktops that are logged in and running. It’s also because it is a potential security hazard to have your VNC server running and ‘out there’ as soon as it boots up.

However, with appropriate security precautions (eg vpn access to the network) it can be done, relatively simply. It’s ideal for remote servers that you might need to reboot, that need to have a graphical environment installed.

I used this article. Although it didn’t work straight away that was because the text USERNAME¬† in the /lib/systemd/system/x11vnc.service file needs changing to the user name you’re using (duh).

command ps -ef | grep [x]11vnc on a remote ssh terminal (on the same network) will tell you if the service is up and running.

After years of faffing this works. I’m using x11vnc and the init (upstart) process for getting the server running from boot. This is on an Xubutnu 15.04 64bit machine
