Joey,

You have a nodes list of >900

Remember that a sysop chooses his own alias.? With 900+ in the nodes list it is possible to have conflicts.? I'm also wondering if it is detrimental to performance.

I like to have a node table that is approximately 5 * (number of forwarding partners)?? Call me crazy but just don't see any reason to have every node in the world listed in my node table.

But that's just me...

You’re not crazy Mark, if you’re seeing > 900 nodes now that means the node limit was raised from 500 from earlier yesterday, this isn’t as you might agree- the way.

For the benefit of all who may be reading-

MINQUAL= ?(above the ports config in the top segment of BPQ config) is the tuning parameter that Joey can tweak, if the AXIP port’s QUALITY is set to 192 for stations heard on it, then a reasonable starting point is setting MINQUAL to 150 and then working downwards once every NODESINTERVAL to capture only desired nodes. Ideally, single hops rather than nodes that I have seen be more than 7 hops away (slow and often duds)
.

As mentioned MINQUAL is tweakable in realtime via the sysop terminal but it won’t survive restarts so the parameter in the config file must be adjusted before each restart to save progress.

—- On a related note about parameters up there, this may be useful info that I am commonly asked about so might be useful for the list (and Joey).


Relating to a tweaked config set up for my pal VK2RZ’s node, its downloadable here:

(Its from an email exchange so excuse the “you” references etc) hi hi.

?

I have set the node parameters up to the absolute maximum a BPQ node can do, adjusting these parameters higher will make them invalid or cause a malfunction should your node ever reach maximum capacity.?

?

I am running ~80+ AXIP links here, and that’s not yet at maximum (128 AXIP maximum possible + up to 16 RF circuits comprised each of a pair of connections into the node). This brings the actual maximum MAXROUTES calculation to 144.?

?

MAXCIRCUITS is calculated by looking at the stream capability of BPQ - it can do a max of 64 streams for applications.

?

When all streams are in use, there are 128 circuits.?

?

The potential maximum number of NETROM users that also create circuits is 16 (two per link, so 32 circuits). Add those together and we get 160 as the absolute MAXCIRCUITS

?

Then the MAXLINKS is derived from adding the MAXCIRCUITS to the maximum possible users coming in via single AX25 connections, which is (if they’re free and not used by NETROM circuits) 32.



I hope this is correct. I got this info from John as some might probably already know my node is a stresstester (hence the silly masochistic test pilot title). Its something I do with all the software and stuff I help out with, probably much to John’s chagrin hi hi.?

If I have posted something incorrect I blame my memory, please do help me refresh it!
