I have recently moved to another place, so this information is out-dated!



Panorama of the view over Heraklion from the roof of my home.
Another panorama. Wider and better resolution. The antenna is actually mounted higher and looks over the trees.

Wireless Node Database: Node 8

Services[edit]

I am operating a file server called tresor at tresor.jimy.node.her.wn, but since I don't have a lot of time right now, it's not publicly accessible at the moment. If you would like to use this file server, please let me know and we see what we can do. Additionally I am co-administrator of the node at Rogdia, which oversees most of Heraklion.

Subnetting scheme[edit]

Illustration of the IPv4 WiFi subnetting configuration (outdated)

All subnets are inside the IPv4 subnet 10.176.1.0/24 and the IPv6 subnet fdd4:f629:b001:0010::/60. The sub-subnets therein will be abbreviated like this:

IPv4
*.32/27 = 10.176.1.32/27

This will make it easier to swap to a separate subnet later.
