Hamachi has some interesting updates

Posted on February 10, 2006 One Comment

I noticed tonight that I had some Hamachi updates to look at. First, I checked the linux client and saw a doozy in the change log!

== 0.9.9.9-13 ==

* Added support for tunneling routed packets, ie packets that are not
destined to peer’s 5.x.x.x address. This is *very* powerful feature.

Consider for example two separate LANs both connected to the I-net.
One LAN is 10.1.1.0/24, another - 10.2.2.0/24 and their default
gateways are running Hamachi clients with 5.1.1.1 and 5.2.2.2 IPs
respectively.

Adding the following routes -

ip route 10.2.2.0/24 via 5.2.2.2 dev ham 0 (on LAN1 gateway)
ip route 10.1.1.0/24 via 5.1.1.1 dev ham 0 (on LAN2 gateway)

will enable LAN-to-LAN communications via Hamachi tunnel that exists
between the gateways.

How sweet is that? Ok, right now I don’t have two lans I need to join, but if I ever make headway with some folks at the office…

The windows (beta) client had some updates tonight as well. Largely related to pulling stuff out of the registry and storing as files. Presumably to make backup up and moving settings a lot easier. My initial reaction was, “sweet — Hamachi on a thumb drive!” but… no, probably not. Not with the interface level changes that are presumably just a bit more involved. Here’s the change log for that one.
