Bill;
A few years back I went to configure my 44.44/16 local net so it included
44.44.44.44. The second it became live, my circuit lost link to it's
tiedown due to excessive botnet flood traffic. It seems as if they
like to use 44.44.44.44 as a test IP of sorts not knowing it's hitting
UCSD.
... just an FYI for ya. Happy Easter/Passover to who it pertains to.

Hi there
Im starting to check the option to install a Wireless lan on 430 MHZ using the Xagyl card ...
Has anyone experienced such wireless networks ?
Most important to me is the Range and non line of sight operation (especially in mobile)
Have anyone done it and can say something on the subject ?

There were concerns that having the data stored in the clear on my site would preset security issues.
The file is now encrypted with 7zip which encrypts filenames also with the pass phrase being 44Index0cAM6wJRCI

Hello everyone,
I'm pleased such a community exists. I requested an allocation about three weeks ago and am excited about getting connected!
The last couple of weekends I put two sdr receivers and a couple of websites up on the public internet for a quick migration to the 44 network when a gateway is received and configured correctly.

Of course. And we had that already in place on the routers inside our own part
of the network (which was deployed to facilitate our co-channel diversity repeater network).
However, above I was discussing the settings on our internet gateway. I cannot control
what all the individual amateurs, with varying networking skills, do on their routers at home,
but by filtering inbound connects to port 8291 I can protect them from the current problem.
There now are 430.000 addresses in the scan I did last night. only net-44 addresses:
44.140.129.12
44-25-128-124.ip.hamwan.net[44.25.128.124]
44.34.131.144
But of course, when people start filtering outbound 8291 connections, it is not a complete picture.

The worm uses port 8291 to identify possible victims (when it can connect to port 8291 it assumes
there is a MikroTik router on that address), then attacks it on port 80 and some other ports that
people may likely have set as an alternative for HTTP access to the router (8080 etc).
So blocking port 8291 effectively blocks the worm in its current version, while not destroying the
useful port 80. Of course experience with earlier events like this shows that such a worm typically
evolves and may skip the port 8291 scan later, rendering this block ineffective.
For now, I have blocked access to port 8291 from addresses outside AMPRnet on our gateway.
Of course this restriction will be lifted when/if this worm stops operation.
It appears to be controlled via a peer-to-peer network and it looks like it is a version of an
existing worm that has been active on network cameras/recorders, routers from other manufacturers,
etc, all running embedded Linux.
