This chapter describes how to use the MSS FTP Service. The following examples assume a command line FTP Client similar to that commonly available on Unix systems.

Connecting to the MSS FTP Service.

Use your FTP Client to connect to host mssftp.ucar.edu. (Normally your FTP Client will connect to port 21 automatically, and the method to specify a port number to use is FTP Client specific.) Enter your UCAS name and password when prompted. At this point you will be placed into your MSS top level directory (with a pathname of a slash / character followed by the upper case version of your UCAS account name). For example:

% ftp mssftp.ucar.edu
Trying 128.117.8.214...
Connected to mssftp.ucar.edu (128.117.8.214).
220 MSS FTP service ready for new user.
Name (mssftp.ucar.edu:auser):

230-This service is available for authorized use only.  Use of this service
 for unauthorized purposes is a violation of federal law.  All activity
 will be logged and monitored, and by using this service, you consent to
 such logging and monitoring.
 NOTE: Put (STOR) commands will limit files written to the MSS to
       500,000,000 bytes unless an ALLO command giving the size of the
       file to be stored is sent first.  Some FTP clients may do this
       for you automatically.

Remote system type is UNIX.
