Fatal: unknown configuration directive 'VRootEngine' on line 16 of '/etc/proftpd.conf'

Hi, after a weekly reboot of my server - it appears proftpd will not start. I have made absolutely no changes what-so-ever and can't work out why it will not start.

Running /usr/sbin/proftpd shows: Fatal: unknown configuration directive 'VRootEngine' on line 16 of '/etc/proftpd.conf'

I checked my /etc/proftpd.conf and it has not changed since september?

This is is here - please advise !!

This is the ProFTPD configuration file

See: http://www.proftpd.org/docs/directives/linked/by-name.html Server Config - config used for anything outside a or context See: http://www.proftpd.org/docs/howto/Vhost.html

ServerName "ITGroup FTP Server" ServerIdent on "FTP Server ready." ServerAdmin root@localhost DefaultServer on

Cause every FTP user except adm to be chrooted into their home directory Aliasing /etc/security/pam_env.conf into the chroot allows pam_env to work at session-end time (http://bugzilla.redhat.com/477120)

VRootEngine on DefaultRoot ~ !adm VRootAlias /etc/security/pam_env.conf etc/security/pam_env.conf

Use pam to authenticate (default) and be authoritative

AuthPAMConfig proftpd AuthOrder mod_auth_pam.c* mod_auth_unix.c

If you use NIS/YP/LDAP you may need to disable PersistentPasswd PersistentPasswd off Don't do reverse DNS lookups (hangs on DNS problems)

UseReverseDNS off

Set the user and group that the server runs as

User nobody Group nobody

To prevent DoS attacks, set the maximum number of child processes to 20. If you need to allow more than 20 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 20

Disable sendfile by default since it breaks displaying the download speeds in ftptop and ftpwho

UseSendfile off

Define the log formats

LogFormat default "%h %l %u %t \"%r\" %s %b" LogFormat auth "%v [%P] %h %t \"%r\" %s"

Howdy -- well, I don't know what might have changed to cause that error -- it could be another proftpd config file that loaded that module may have changed.

However, since it's complaining about that VRootEngine line, I'd try commenting it out and then restarting ProFTPd.

yes, I can (and have) done that - and yes, it starts. However, that does not chroot users to their own directories - which is dangerous. Can you supply the default proftpd.conf file contents from a Virutalmin install and I can check what is different - or advise otherwise? thank you !

I just did that - Proftpd starts, but when I try to ftp (using a multitude of usernames) - I cannot logon?

That's odd, as Virtualmin and Webmin never set the VRootEngine directive ..

Which ProFTPd package version are you using exactly?

Whenever installing ProFTPd, Virtualmin doesn't make any changes from the default config.

Also, when enabling directory restrictions, Virtualmin doesn't use the VRootEngine parameter; instead, it sets the "DefaultRoot" parameter.

However, that does not chroot users to their own directories - which is dangerous.

Well, we disagree, for the reasons described here:

https://www.virtualmin.com/documentation/security/faq

A user can simply upload a PHP-based filemanager, or use SSH, to gain access to files they have rights to view. So the key is to make sure that users don't have rights to view files they shouldn't be able to see, or to use containers such as VPS's to fully restrict them.

However, we appreciate that folks wish to provide restrictions for FTP users anyhow :-)

What you may want to do is verify that in Limits and Validation -> FTP Directory Restrictions, that a home directory restriction is still enabled.

As far as not being able to login via FTP -- what errors do you see in /var/log/secure when attempting to log in?

thank you for your reply. I don't mind either way - i just want it to work ! I have tried nine different (known working) logons - and all fail.

/var/log/secure shows "(Login failed): Incorrect password." for all of them.

please advise.

any update on this please - no one can logon - please HELP !!

Well, one of the keys might be the question Jamie had asked above -- what ProFTPd version are you using there?

You can determine that by running this command:

rpm -qa | grep proftpd

sorry, missed that one...

proftpd-1.3.4a-1.el6.rf.i686

is what it shows.

That may be your problem -- that's a package from a non-standard repository, the RPMForge repository.

It looks like someone had enabled that repository on your system, and ProFTPd was pulled in from it.

We don't know anything about ProFTPd from that repository, or how it would work with your current configuration, and it's likely that's related to the problems you're having.

Our recommendation would be to disable the RPMForge repository, and then reinstall the version of ProFTPd that comes with Virtualmin.

You can download the i386 version of the CentOS 6 ProFTPd RPM with this command:

wget http://software.virtualmin.com/gpl/centos/6/i386/proftpd-1.3.3e-1.el6.i686.rpm

After you download it, you can install it with this command:

rpm -Uvh --oldpackage proftpd-1.3.3e-1.el6.i686.rpm

done - and fixed - thank you !!!!!
