ProFTPD on Solaris 8 (as anonymous):

Pre-install tasks:

Then add the "ftp" account for anonymous
# /usr/sbin/groupadd -g 3001 ftp
# /usr/sbin/useradd -c "Anonymous ftp" -d /export/ftp -g ftp -m -u 3001 ftp

Now disable "ftp" from remote logins
# grep ftp /etc/passwd
ftp:x:3001:3001:Anonymous ftp:/export/ftp:/bin/sh

edit the line containing "ftp" and remove the field for the shell "/bin/sh" so
that you end up with:
ftp:x:3001:3001:Anonymous ftp:/export/ftp:

Note: You could also use "noshell" from the Titan compilation:
http://www.fish.com/titan/TITAN_Solaris8.html

Now lock out root from ftp use
# echo "root" >> /etc/ftpusers

Installation tasks:

Name (kinscoe:kinscoe): 

Ok good it is built and now manually running.

kinscoe (kinscoe[167.208.5.13]) - connected - local  : 167.208.5.13:21
kinscoe (kinscoe[167.208.5.13]) - connected - remote : 167.208.5.13:33572
kinscoe (kinscoe[167.208.5.13]) - FTP session opened.

Now do a control-C to kill it.

^C

Now to setup the configuration:

This is the /usr/local/etc/proftpd.conf I used:

# This is a basic ProFTPD configuration file (rename it to 
# 'proftpd.conf' for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.

ServerName                      "kinscoe.harcourt.com"
ServerType                      standalone
DefaultServer                   on

# Port 21 is the standard FTP port.
Port                            21
# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask                           022

# To prevent DoS attacks, set the maximum number of child processes
# to 30.  If you need to allow more than 30 concurrent connections
# at once, simply increase this value.  Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd)
MaxInstances                    30

# Set the user and group that the server normally runs at.
User                            nobody
Group                           nogroup

# Normally, we want files to be overwriteable.
<Directory /*>
  AllowOverwrite                on
</Directory>

# A basic anonymous configuration, no upload directories.
<Anonymous ~ftp>
  User                          ftp
  Group                         ftp
  # We want clients to be able to login with "anonymous" as well as "ftp"
  UserAlias                     anonymous ftp

  # Limit the maximum number of anonymous logins
  MaxClients                    10

  # We want 'welcome.msg' displayed at login, and '.message' displayed
  # in each newly chdired directory.
  DisplayLogin                  welcome.msg
  DisplayFirstChdir             .message

  # Limit WRITE everywhere in the anonymous chroot
  <Limit WRITE>
    DenyAll
  </Limit>

</Anonymous>

Now setup ProFTP to run in place of Sun's in.ftpd:

http://proftpd.linux.co.uk/docs/faq/proftpdfaq-4.html#ss4.8

Find the line in /etc/inetd.conf that looks something like this: 

ftp     stream  tcp6    nowait  root    /usr/sbin/in.ftpd       in.ftpd 

Replace it with: 

ftp     stream  tcp6    nowait  root    /usr/local/sbin/proftpd /usr/local/sbin/proftpd/proftpd -d9

No rehup the inetd:

kill -HUP `ps -ef | grep /usr/sbin/inetd | head -1 | awk ' { print $2 }'`

Setup software distros:

# cd /export/ftp
# find . -exec chown ftp {} \;
# find . -exec chgrp ftp {} \;
# find . -exec chmod 555 {} \;
