Error with restarting proftpd server SQL mod

Hi

I hope you can help me..

I followed your guide to install a proftpd server on ubuntu so i tried it on
ubuntu 9.04

http://www.howtoforge.com/virtual-hosting-with-proftpd-and-mysql-ubuntu-8.04


The only difference is that

apt-get install proftpd-mysql gave me this error:

gert@gert-desktop:~$ sudo apt-get install proftpd-mysql
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package proftpd-mysql is not available, but is referred to by another
package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package proftpd-mysql has no installation candidate



So I googled a bit and installed it like this:

sudo apt-get install proftpd-mod-mysql

Actually I don't really know what i'm doing here..

So everything goes fine. I can connect to my SQL database and phpmyadmin is
working and I see the tables but when I want to restart the proftpd server
with the configured proftpd.conf file I get this error..


- Fatal: unknown configuration directive 'SQLBackend' on line 173 of
'/etc/proftpd/proftpd.conf'


Are there any things I need to check to make sure I have a correct version
of proftpd installed?

Greetings and thanks in advance,

Gert

I guess you must either uncomment

Code:

Include /etc/proftpd/sql.conf

or make sure that the MySQL module is enabled in /etc/proftpd/modules.conf.

 

Ok,

enabling the right module brings me a step further..

root@gert-desktop:/etc/proftpd# /etc/init.d/proftpd restart
* Stopping ftp server proftpd [ OK ]
* Starting ftp server proftpd /etc/init.d/proftpd: line 88: 7874 Segmentation fault start-stop-daemon --start --quiet --pidfile "$PIDFILE" --oknodo --exec $DAEMON -- $OPTIONS



A segmentation fault

 

What exactly did you change?

Can you run line 88 from /etc/init.d/proftpd manually on the command line? Make sure you replace variables like $PIDFILE, $DAEMON, and $OPTIONS with the right values (the variables should also be defined in /etc/init.d/proftpd).

 

I had the very same issue myself:

For me it helped editing the /etc/proftpd/modules.conf file.

Once in there the thing I've missed that caused the above issue was the setting called:
# Install proftpd-mod-mysql or proftpd-mod-pgsql to use this
LoadModule mod_sql.c


I don't really dare running the ftp server 24/7 though since there's only v. 1.3.1 in the ubuntu repos (the one I have installed) and i've got some bad experiences from installing from source. Awaiting patiently the .deb package!
