 |
|
I think this is of interest to the dev community as a whole; as such, Im posting a project advertisement here. The Bioware Developer Forums do not seem to do much traffic these days.
Im working on a nwserver replacement, written as free software, in Java. For that to work, I'll have to dissect the protocol used by nwserver - since I want to provide compatibility to NWN clients out of the box.
Im sure I don't have to tell you of the advantages this would bring. ;)
If you're interested in helping, please have a look at http://nwn.bioware.com/forums/viewtopic.html?topic=554366&forum=74
Thanks. :) |

Recognition of:
- Compound packets
- Multi-part messages (split into several packets)
- Compressed packets (no decompression yet.. I haven't found a way to decompress it)
- Packet headers
- Message headers (direction, message type, subtype, etc.)
- Message data dissection for message type 0x7|0x4 (Open store) |

this is great stuff. A very similar idea has been occurring to me on and off over the last few weeks. Is this project still active?
Another advantage of this is that nwscript itself can be extended or replaced, providing hooks into the things that don't presently have hooks...
(This would also be great for NWN2, since most of the underlying networking protocols are unchanged...)

I was trying to wrap my head around that last year, and eventually gave up.
Couldn't find any known algorithm (tried about 6) that produced the same compression even working with known data such as long text strings that I sent via text.

| I looked at this two or three years ago... The compression was gzip IIRC. I'll try to find my notes tonight ... but that was 2 or 3 hard drives ago |

Yes, it's gzip (zlib-stream).  |

Yes, this project is "live" insofar that I am still willing to write it.
However, professional time constraints do not allow me to spend any big amount of time on protocol dissection. Someone would have to help me out draft up some specs for the client communication, or it'll never go anywhere soon. |
