I have recently setup a SLackware10.1 box running proftpd. proftpd is started by inetd.
The system has one normal user. This user has (for some reason) ftp access (at least read) to the whole file system.
This is not the intention and I like to know how to solve this.
tells me to chroot the user to his home directory. Also, searching this forum refers to chroot.
I've added the bold lines to proftpd.conf and restarted inetd (I assumed that that's necessary as proftpd started by inetd).
# This is a basic ProFTPD configuration file.
# It establishes a single server and a single anonymous login.
# It assumes that you have a user/group "nobody" and "ftp"
# for normal/anonymous operation.
ServerName "ProFTPD Default Installation"
# Port 21 is the standard FTP port.
# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
# 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)
# Set the user and group that the server normally runs at.
# This next option is required for NIS or NIS+ to work properly:
# Normally, we want files to be overwriteable.
# A basic anonymous FTP server configuration.
# To enable this, remove the user ftp from /etc/ftpusers.
# We want clients to be able to login with "anonymous" as well as "ftp"
UserAlias anonymous ftp
# Limit the maximum number of anonymous logins
# We want 'welcome.msg' displayed at login, and '.message' displayed
# in each newly chdired directory.
# Limit WRITE everywhere in the anonymous chroot
# An upload directory that allows storing files but not retrieving
# or creating directories.
# <Directory incoming/*>
# <Limit READ>
# <Limit STOR>
This does not seem to do the trick. It also does not make sense to me as I don't want a virtual host. Seeing the word 'DefaultRoot' then also does not make sense, it's just the default.
So how can I limit user access? Thanks in advance
The user only belongs to group users
I ran Slackware 10.0 before with proftp and can't remember that I had this problem (stock standard worked as far as I can remember).
