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. Smilie

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,

ftpconfig

ftpconfig(1M)						  System Administration Commands					     ftpconfig(1M)

NAME

       ftpconfig - set up anonymous FTP

SYNOPSIS

       ftpconfig [ftpdir]

       ftpconfig -d ftpdir

DESCRIPTION

       The ftpconfig script is executed by the super user to set up anonymous FTP. Anonymous FTP allows users to remotely log on to the FTP server
       by specifying the user name  ftp or anonymous and the user's email  address as password. The anonymous users  are  logged  on  to  the  FTP
       Server  and  given  access to a restricted file area with its own file system root. See chroot(2). The FTP area has  its own minimal system
       files.

       This command will copy and set up all the components needed to operate an anonymous FTP server, including creating the  ftp  user  account,
       creating  device  nodes,  copying  /usr/lib files, and copying timezone data.  The passwd and group files set up have been stripped down to
       prevent malicious users from finding login names on the server.	The anonymous file area will be placed	under  ftpdir.	If  the  ftp  user
       account already exists, then the current FTP area is used, and the system files in it are updated. All other files are left untouched. This
       command should be run to update the anonymous FTP area's configuration whenever a system patch is installed, or the system is upgraded.

OPTIONS

       -d     Create a new or update an existing ftpdir without creating or updating the ftp user account. Use this option when creating guest FTP
	      user accounts.

OPERANDS

       The following operands are supported:

       ftpdir	 The absolute pathname of the directory under which the anonymous FTP area is set up.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion

       1     Improper usage of the command

       2     Command failed

ATTRIBUTES
