Can I please have info on the peering for IP and any other config details that may help. I will be using a DECbrouter 90 (Cisco) V11.1. So, anyone know if the DECrouter will do, and who would be willing to act as a peer? Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B. Idol Hmmm... Didn't know much about DECbrouter until I looked it up following these emails. If I have it right (http://manx.classiccmp.org/collections/mds-199909/cd2/network/decbroma.pdf) all DECbrouters have only one Ethernet interface and a one or more (depending on model) WAN connections using synchronous serial lines. I am wondering how this could be used on HECnet. I don't think anyone offers any synchronous serial way into HECnet, or am I wrong? That leaves the one Ethernet interface. To be able to use that would need the bridge (or my user mode router, or some other hardware router) to be on the same LAN. But at that point there wouldn't be a lot of point having the DECbrouter as it would not have anything to route. Have I missed something? Is the DECbrouter 90 (Cisco) a different beast? Regards Rob I should be able to set up the DECbrouter 90 as a one armed router behind my main internet Router which is a Cisco 1800. All I need it for is to encapsulate DECnet and then forward it to a peer via my internet connected router. It won't be the highest performance but it will get the Area up, I can then change it at a later date if required. BTW, my Cisco 1800 does not support DECnet or GRE so this is not an option. Does anyone have any peering info or the config used either on a Cisco or DECbrouter. Hi Mark, I have a Cisco 857 which provides my connection to the 'net. I have the following NAT rules on my Cisco 867 (gatekeeper) to pass GRE/IP packets through to my DECbrouter 90T2: interface Vlan1 ip address 172.17.111.254 255.255.255.0 ip nat inside interface Dialer0 ip nat outside ip nat inside source static tcp 172.17.111.251 1723 interface Dialer0 1723 Then on my DECbrouter 90T2 (a12rtr) I just set up the tunnels, like so: interface Tunnel52 description HECnet tunnel for ... no ip address decnet cost 20 tunnel source Ethernet0 tunnel destination .... However, as Dave pointed out (and I said earlier) when Brian catches up with the list he can add you to the mesh and you will receive all the configuration details from him. I am also likely able to track down a version of the Cisco 1800 IOS that can do DECnet and GRE/IP (if you're interested). Regards, Tim. Hi Tim, Did you manage to find a version of IOS for the 1800 that could support DECnet? Thanks, Mark

Any of you guys got a recommendation as to what USB-serial adapter works best in Linux? I have used two, both of which work fine with Linux on a PC: the FTDI "chip in the cable" adapters, and one made by TrippLite (sold at Staples). However, neither was recognized by my BeagleBone (which runs ARM Linux, ngstr m distribution). That may well be just a case of not having the right modules installed. I don't use Raspberry PI (I prefer the open hardware that I get with BB) but since it too is ARM the situation might be the same. Then again, BB also comes with a Ubuntu distribution, which might have the necessary USB modules included as standard. Finally, again on BB, there's an additional option: that device has 6 built-in UARTs, of which 5.5 are available on connectors (one on a 6-pin "debug" header, the rest on the 2x46 pin expansion connectors). Those are 3.3 volt logic levels, but you can get, or build, RS232 adapters for them. I just built a 4 port RS232 adapter, in fact. So with that, you don't need any USB devices at all and the stock small OS build is sufficient. paul

Actually, I've had problems finding ones that won't work in Linux -- including the really cheap $8.00 ones of eBay. The ones that stopped working in Windows7 all still work in Linux. The ones with the FTDI chipset are supposed to be the most stable and best. http://www.ftdichip.com/FTDrivers.htm http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_USB_RS232_CA… One vendor with that chipset appears to be: http://www.usconverters.com/index.php?main_page=product_info&cPath=67&produ… -- d|i|g|i|t|a|l had it THEN.

If you can stand not having advanced handshaking it's very easy to tack a native serial port onto the GPIO connection. It's a better solution IMHO. You will need a TTL to RS232 level shifter and some link wires. Be aware some RS232 level shifters with ports are ALREADY crossed over (mine is) so mak sure you're clear on it. While USB to RS232 adapters are largely fine I've had some nasty quirks using them with SimH.
