I am newbie and intended to use my Redhat Linux 4.2 and Netscape on my
P90 computer to serve the net. I'm also running Win95 on the same
computer which has two hard disks.The second hard disk was partioned to
run Linux.
I sucessfully installed Linux and PPP and was abled to connect to my ISP
using Linux.
Next I downloaded Netscape Communicator for Linux 2.0 from the Netscape
site using Win95 on my DOS partition. It a huge compressed file
'comm...linux2_0_tar.gz'. I booted linux and mount the DOS partion and
copied the file over to a Linux directory.
I tried gunzip, zcat, uncompress but was unable to unzip and tar the
huge file. The error message was 'invalid compressed data -- format
violated' using gunzip.
A check with the 'file' command revealed that the file is compressed
using gzip, deflated and the os:unix. Seems normal.
Could it be one of the following
(a) .gz file was corrupted during download. But I had similar problems
with other smaller downloaded file.
(b)(not a binary file). Modified during the downloading process.
Netscape on Win 95 treated the .gz file as html or text. I had to issue
a 'save as' command when downloading. If so how do I download as binary?

(c) incompatibility from coping between DOS and Linux partitions. I
noticed that the .gz file was trucated in the DOS partition.
Please help urgently.
