MVS compression that unix can uncompress
Dear all,
I have been given the opportunity at the last minute to help on a project. There is a need to move some very large files from an MVS machine to an AIX one. The servers are remote with (I think) a 2Meg network pipe between them. The people on the project have been moving small amounts of data and proving that their export/FTP/import works, but they never considered elapse time for the full sized data transfer.
Consequently our window of a weekend to move the data is nowhere near long enough because of the network bottleneck. Would anyone know of a compression tool that runs on MVS that produces files that could be read back by normal unix tools i.e. uncompress or gunzip
I love it when it's suddenly my fault when the FTP is too slow.
Someone looking after the MVS end is considering PKZip but there is then product to install & licence on AIX too. As the MVS support is outsourced, I'm having trouble finding out who is looking at that, but presumably it's from PKWare.com
I considered PGP as part of the encryption process compresses the data, but I'm struggling to find a source for the MVS tool.
Any suggestions?
Many thanks, in advance,

FTPUSERS(5) Linux Programmer's Manual FTPUSERS(5) NAME
ftpusers - list of users that may not log in via the FTP daemon DESCRIPTION
The text file ftpusers contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon. This file is used not merely for system administration purposes but for improving security within a TCP/IP networked environment. It will typically contain a list of the users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP server daemon. Such users usually include root, daemon, bin, uucp, and news. If your FTP server daemon doesn't use ftpusers then it is suggested that you read its documentation to find out how to block access for certain users. Washington University FTP server Daemon (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers. Format The format of ftpusers is very simple. There is one account name (or username) per line. Lines starting with a # are ignored. FILES
