Chapter 7 HPSS User Interface ConfigurationHPSS Installation Guide September 2002 423Release 4.5, Revision 2possible, use a “TCP Wrapper” application for initiating the HPSS FTP Daemon. Thisenhances on-the-fly changes to the startup of the HPSS FTP Daemon. Additionally, thisprovides for enhanced security. Several TCP Wrapper applications are available in thePublic domain.HPSS Parallel FTP Daemon options:The only options which accept additional arguments are the –p, -s, -D, and –F options. The –prequires a port number (decimal value) while the other D and F options expect strings <MAXPATHLEN characters in length. The syntax on the –s option is explained below and shouldbe handled carefully or indeterminate errors may occur! No space is allowed between the optionand the value. NOTE: that using long strings MAY cause severe problems for inetd! Each of thesefour options MUST be preceded by a space and a “-“. In general, it is recommended that these fouroptions NOT be used!All the other options should be specified by a single “-“ at the start and the concatenation of options(e.g., “-abdddhtuvzARSTUX” – Not necessarily in that order)NOTE the three consecutive “d”s imply to “syslog” as much debug information as possible. Seethe explanation below for the “d” option.Table 7-1 Parallel FTP Daemon OptionsOption Descriptiona Mandate Authentication with DCE/Kerberos Credentials -Disable{Username}/{Password} authentication. This also disables theuser command.b Read the hpss_option BUFSZ option from the {ftpaccess}file to obtain the path/name of the size specification to be used. Refer todocumentation on the {ftpaccess} file for more details.d Turn on Debugging - Increments environment variable HPSS_DEBUGand sets HPSS_DEBUGPATH=FTPBaseDir/adm/hpss_ftpd.log.See option -D for details on FTPBaseDir. This option may be repeatedup to 3 times. Each specification increases the detail of debuginformation sent to the syslog. NOTE: the information in the syslog issubject to the specifications in /etc/syslog.conf. For the mostinformation, specify *.debug in /etc/syslog.conf.h Search the ftpaccess file for the HOST specifier - Defines the networkinterface to be used for data transferred between the PFTPD and theMovers when performing non-parallel transfers. hpss_option HOST option sets the HPSS_HOSTNAME environmentvariable for the Client API. Refer to documentation on the ftpaccessfile for details.p# Specify a port to be used by the HPSS PFTP Daemon. Used only wheninitiating the Daemon manually (rather than using inetd).
