Re: Portknocking by script.

You could use a variation on port knocking but using icmp and various packet sizes.

Then the client can use the ping command with size set to execute the knock

Hope that helps

Ooh, I like that. ICMP packet sizes are also pretty obscure to someone sniffing the wire.

Hi Myron in router-a i can ping 10.13.0.2 but if im in router b it wont ping 10.13.0.1 using laptap connected to 10.14.0.0/24 If you're trying via a laptop connected to router b, then also check that your laptop has either a default route via 10.14.0.1 or has a route to 10.13.0.0/24 via 10.14.0.1.

Re: 802.11n

Does each chain (or antenna port) using .11n use a seperate 20Mhz channel or do they all share the same 20Mhz and transmit at the same time and recieve at the same time? I've not found any good documentation to explain that. they all share those 20mhz and transmit and receive at the same time. Hi U...

Re: Xen won't go

Will MetaRouter run on x86 hardware, or just routerboard? I'm using x86 based servers in a co-host facility.

Is there any feature difference with Xen and MetaRouter?

Whilst Xen is very useful (particularly if you're trying to save on datacentre hosting fees), it is still a bit buggy, and I believe MT are openly stating that Xen is in an "alpha" status righ...

Hmmm... this does seem a little odd. How much RAM does the machine have anyway? I'm a bit suspect that your "main" MT is still showing over 300mb of memory when you've set the limit at 128mb. When I first started playing with Xen I had a number of very similar issues - ie: VM fails to start, but log...
