Re: Problem operating GNUgk 2.2.1 under a Directory Gatekeeper

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently you cannot do this - another solution is to keep
the directory gatekeeper (A) on the LRQ/LCF path, so LCF
is first sent to the gkA and then to the originating gatekeeper.

I have been trying to have a GNUgk 2.2.1 operate as a peripheral
gatekeeper to a Directory Gatekeeper Hierarchy.

I would like the GNUgk (B) to only be aware of the
Directory Gatekeeper (A) and none of the other gatekeepers (C)
participating in the hierarchy.

Here is the diagram:
   gk-A
  ___|______
  |        |
GNUgk-B   gk-C ...

Whenever (B) LRQs the directory gatekeeper (A), it may receive LCFs
either from (A) or from other gatekeepers like (C),
which are not necessarily defined as neighbours in (B).

LCFs returned by (A) are handled OK on GNUgk, since (A) is defined as a
neighbour, but LCFs returned by (C) are blocked ("Trapped"),
with the following error log:

2005/01/26 17:06:27.610 2 RasSrv.cxx(1240)RAS Trapped LCF
2005/01/26 17:06:27.610 1 Neighbor.cxx(639)RAS Unknown reply LCF
2005/01/26 17:06:30.617 2 RasSrv.cxx(168)RAS Read from 155.207.12.79:3607

This behaviour seems to make it very difficult for GNUgk 2.2.1
to participate in directory gatekeeper hierarchies.
This was not the case with GNUgk v.2.0.8.

Is there a configuration directive to allow the GNUgk to accept
all LRQ/LCFs from any gatekeeper, whether a neighbour or not?

I have been offered a patch to the code that will prevent this check
from taking effect, but I would prefer a clean solution,
through the config file.

All help is appreciated.
Regards.
