Dynamic DNS Update on N900

I've created a maemo package to do Dynamic DNS updates each time the N900 connects to the Internet.

Install file here.

I am not sure if automatic install works yet - but do check it out (It does not work right now - need to change section from net to user/net - I will do that tonight).

It does however work by adding the repository and to and "apt-get install ipcheck".

Configuration needs to be created in a terminal (yes - I should do a gui config - but I can't be bothered - any volunteers?).

$ cat /etc/ipcheckrc >.ipcheckrc
$ vi .ipcheckrc

Fill in data for DYNDNS_HOSTNAME, DYNDNS_USER and DYNDNS_PASSWORD.

That's about it.

    So - anybody want to help creating a small gui that can edit those 3 values? Can it be done with a small python script?
