non-HPSS Parallel FTP Daemon (DIS

COM PFTP Daemon). This file should be customized as needed.

Refer to the HPSS.conf man page or the HPSS Installation Guide, Appendix D for details. NOTE: it
may be necessary for a site to merge older copies of the HPSS.conf file with the template if modifications
have been made since the prior release. There is no conversion job to perform this task.

Step 2. Configuring the FTP/PFTP Daemon Syslog

The PFTP Daemon attempts to write to the system log (using syslog()). To enable this output, follow
local system procedures for capturing this information. The PFTP Daemon writes to the
LOG_DAEMON syslog facility.

Step 3. Defining the PFTP Access

In the following statements, {FTPBaseDir} defaults to "/var/hpss" and {ftpaccess} defaults to
"ftpaccess". These values may be changed in the HPSS.conf file. The {FTPBaseDir}/etc/{ftpaccess}
file defines access, options, and restrictions for the server. An ftpaccess.tmpl file is provided in the
$HPSS_ROOT/config/templates directory for the HPSS Administrator to customize appropriately. The
pound sign (#) at the beginning of a line indicates a comment. Options are enabled by removing the
comment symbol (#) and conversely disabled by introducing this symbol. Some options are specific to
individual machines, so each HPSS Parallel FTP Daemon should read its own {ftpaccess} file.

The access options can be defined as follows:

# Define a class of users.
# class { anonymous | guest | real }
[ ... ]
#
# is a full network address, including wildcarding, e.g.,
*.nsl.nersc.gov.
class hpss_class real *
class hpss_anon anonymous *
#
# Define a limit on the number of users from a certain class
# that can be using the ftp server at specific times.
# limit [] []
#
# The clause has the following format:
# -|-|... (no white space!)
# or "Any"
# where is one of "Su", "Mo", "Tu", "We", "Th", "Fr",
# "Sa", "Wk"
# "Wk" matches any day of the week
# is the time in 24-hour format
# "Any" matches any day and time
# (used to specify for all days and times)
# limit hpss_class 1 Tu0600-1200
limit hpss_class 3
