I am reading some UDP packets whose payload has been compressed using
windows only library "xceed zip verion 4.2"

I am trying to uncompress the UDP packets payload on a Linux box. I
have no idea what compression algorithm the windows library   "xceed
zip verion 4.2" is using.

How will I go about reverse engineering what compression algorithm was
used so that I can use the proper uncompression algorithm.

Here are 5 sample compressed packets:

http://www.debtconsolidationcare.com/rnd/zip/compressedpacket.3.txt
http://www.debtconsolidationcare.com/rnd/zip/compressedpacket.4.txt
http://www.debtconsolidationcare.com/rnd/zip/compressedpacket.5.txt

and here is the data that is being read from the network:
