Example 1: Setting Up An Anonymous Ftp
SunOS 5.7 Last change: 4 Mar 1997 5
Maintenance Commands in.ftpd(1M)
To set up anonymous ftp, add the following entry to the
/etc/passwd file. In this example, /export/ftp was chosen to
be the anonymous ftp area, and the shell is the non-existent
file /nosuchshell. This prevents users from logging in as
the ftp user.
ftp:x:30000:30000:Anonymous FTP:/export/ftp:/nosuchshell
Add the following entry to the /etc/shadow file:
ftp:NP:6445::::::
ftp:NP:6445::::::
The following shell script sets up the anonymous ftp area.
It presumes that names are resolved using NIS.
#!/bin/sh
# script to setup anonymous ftp area
#
# verify you are root
/usr/bin/id | grep -w 'uid=0' >/dev/null 2>&1
if [ "$?" != "0" ]; then
echo
exit 1

case $# in
# the default location for the anon ftp comes from the
passwd file
