Planning on switching to digest mode, so I do not continue to get such an uncanny amount of emails per hour.. But even at that we need to remember to be considerate and TRIM inclusions.. Perferrably all the way out.. Or at least severely miniize the amount of carry over. Or else in a 24 hour period we can have a digest too big to want to swim thru.... Or possibly one that exceeds our email inbox size limit.. Thanks Everyone have a good weekend.. Jerry

Re: [44net] directly routed subnets

by Tim Osburn

Brian and All, I always thought it was a waste of a routable /8 to not have it routed on the Internet, otherwise why are people just not using IANA space instead? However, if it is to be routed on the internet I think some ground rules must be established of what is and is not acceptable and penalties for not following the rules and established guidelines. Additionally, and I bring this up again, a RWHOIS server should/must be used (tied in with ARIN on the 44/8 allocation) so that people can query specific address space that will return the contact/owner of whatever space is being advertised for whatever reason. Additionally, IRR entries should also be required for anyone wanting to advertise space via BGP. Those should be some common sence polices that need to be followed at the very minimum. Obviously nothing smaller then a /24 should be advertised on the internet as most Tier 1 carriers will block any address space that is smaller in their BGP configs. I don't know what the whole breakup of space looks like within each coordinator's /16 space (for those that have a /16 of space), but I would think there surely is space in each that could be a usable /24 or larger that could be utilized for that. Alternatively there seems to be a lot of space at the upper end of the 44 block that could be used for internet routed blocks if we wanted to use that first? IP Space justification will be whole issue within it's self as well, because if you only REALLY need /28 or /27 of IP's, one will still need to advertise a /24. Perhaps who ever advertises space via BGP should accept the condition that if only a portion of the advertise space is being used that you will accept and allow another person needing the available space so that it's not wasted. This could be tracked and allocated via the rwhois server in conjunction with entries in IRR. UCSD can still advertise the 44/8, and of course if anyone advertises a more specific route, that will be preferred of the larger aggregate. Be nice if we were all on a IRC chat channel to bounce ideas around? If anyone is interested, how about channel #44net on IRC server network freenode (irc.freenode.net). I'm on there now.

Using a cisco to do the tunnelling

by VK4FQ/VK4TTT Sam

Hey Guys We have a surplus of cisco routers with dsl wics due to an upgrade. We have put DSL into a few of our repeater locations and want to put packet (before the 12/13 storm season) I am looking for a config that will do the ip tunnel encap for 44 net. If you have done it please email me vk4fq(a)smellyblackdog.com.au with destructions please Samantha vk4fq/vk4ttt

Hardware wise USB serial adapters could run legacy hardware such as TNC's, modems, and even do such functions as rotor control and radio tuning for sat links, etc. Ethernet would connect the box to the local subnet(s) and the internet. Ideally one could plug a TCP/IP host or network in one port ( the local net... generally a PC or Mac but it really wouldnt matter), The Internet on the second port, and the local AMPRNET RF WiLAN on the 3rd port.

Re: [44net] 44net is not just for tunneling and more

by K7VE - John

*Disclosure* - I am affiliated with NW Digital Radio, but my comments here concerning features, design decisions, product direction, availability, price, or delivery are not guarantees, announcements, or binding upon the company unless specifically stated as such. Someone brought up the UDR56K-4 radio announced at Dayton Hamvention® a couple of weeks ago. So let me list some parameters and answer a couple of questions: - The model announced is specified as a half duplex radio, running 25W on 70cm band. - It has an integrated computer running a standard Linux server (Debian Squeeze) with additional drivers specific to the radio. - The software platform is open source and developers are free to create their own protocols and applications - Additional hardware and options can be added via USB or 10/100 Ethernet. - There will be a daughter card option to hold a vocoder (AMBE family card will be available from NW Digital Radio) - AX.25 and D-STAR network stacks are under development and test, supporting applications that use those network stacks. - Modulation choices include GMSK, FSK, 4FSK, and possibly one or two additional choices. The modulation is performed in a high integration RF IC which talks through a bus directly at digital logic levels (no analog/base-band layer) - The RF IC can accept up to 100 Kbps with bandwidth profiles based on modulation choice. The US regulations limit operation to 56 Kbaud and 100 KHz bandwidth. Higher bit rates that meet those requirements can be supported up to the 100 Kbps rate. The developer/operator is responsible for insuring data rate / modulation choice meet the regulations where the radio is deployed. Having addressed the basics relative to the radio. The idea is to have a platform to support multiple applications including AMPRnet. There is an interest in other common air interface (CAI) protocols for passing various data including Net-44 packets, we have at least one 3rd party developer who wants to add a low-overhead IP transport to the radio. Yahoo! Forum for discussions relative to the UDR are at http://groups.yahoo.com/group/UniversalDigitalRadio One thing to remember is that for a given power one must choose between distance, reliability, and speed. For example, using 4FSK it may be possible to push the raw bit rate above 80 Kbps within 100 KHz, however it might be worth using a forward error correcting code reducing the effective rate back to 56 Kbps while reducing retries on a given path due to bit errors. I think that Net44 as a replacement for broadband service is not a goal that we should be seeking. In the wireless space there are plenty of consumer devices (Part 15 in the US) that can provide high-speed/local service, e.g. WiFi, or even point-to-point links on some paths. There are a lot of applications where repurposing consumer devices makes sense, e.g. HSMM on amateur bands, or very local mesh networks in urban areas. Conversely, there are many applications where longer haul, higher power, modest data rate service is a better choice and this is where Amateur Radio can fill a need. I agree we should work to multi-home Net-44 to the rest of the Internet, but I don't believe we should do this on a LAN level. I think at most it should be the 256 /16 subnets and probably many fewer than that. Local LANs can tunnel using newer tunneling protocols that can use a dynamic IP on at least one end of the tunnel to these BGP'ed routers (with fail-over between them for tunnels from LANs). There is no reason to use roll-your-own routers or protocols -- there are very capable routers with tunneling in the US$60 range that can get the connection over the Internet tunnel to the local LAN, then use our various RF interfaces (WiFi/HSMM, AX.25, DSTAR, ...) out to individual nodes.
