# Subject: Re: Solaris 2.1 anonymous ftp setup
#
# Use the above script to setup anonymous ftp.
# -OonGil
#
# Steps for setting up anonymous ftp under Solaris 2.1.
# 1. read the ftpd(1M) section for background.
# 2. create /etc/shells populated with your favourites.
# 3. establish the ftp user account and home directory.
# 4. run this script as root.
#
# Function of necessary files:
#
# Needed for 'dir' and 'ls' functionality.
# /bin/ls
#
# The following are needed for basic operation.
# /usr/lib/ld.so*
# /usr/lib/libc.so.1
# /usr/lib/libdl.so.1
# /usr/lib/libintl.so.1
# /usr/lib/libw.so.1
# /etc/passwd
# /etc/group
# /etc/netconfig
# /etc/nsswitch.conf
#
# The following are needed for 'ls' to resolve NIS names.
# /usr/lib/nsw*.so
# /usr/lib/libnsl.so.1
# /usr/lib/straddr.so

# OPERATIONS:
# a function for copying files:
filcopy(){
	f=$1
	ff=`basename $f`
	d1=`dirname $f`
	expr "$d1" : "/.*" >/dev/null 2>&1 && fd=`expr "$d1" : "/\(.*\)"`

	# for cleansing:
	/bin/rm -f ${FTP}/${fd}/$ff ] && cp $f ${FTP}/${fd}

	# for quicker operation:
	# [ ! -f ${FTP}/${fd}/$ff ] && cp $f ${FTP}/${fd}

	echo "cp $f ${FTP}/${fd}"
}
