Monit says: Proftpd "Execution failed"

Since a quiet long time i use Monit as my system monitor.
Since yetserday Monit says that the status for Proftpd is "Execution failed".

I wonder how this is possible, because uploading/downloading files via ProFTP is no problem at all and is going quiet fast.
What could be the reason for this?

I have restarted Proftpd and monit as well, but this makes no difference.

 

Can you post the Proftpd part of your monitrc file?

 

Within the attachement you find the output of the file.

 

What are the outputs of

Code:

ls -la /var/run/proftpd.pid

and

Code:

netstat -tap

?

 

no pid file found

Falko,

I think the problem is that the pid-file can not be found, because the output of ls -la /var/run/proftpd.pid is: no such file or directory



How can this be solved?

netstat -tap has a line like this:

tcp 0 0 *:2812 *:* LISTEN 18237/monit

 

If you are absolutely sure that Proftpd is running, run

Code:

updatedb
locate proftpd.pid

What's the output?

Also, check /etc/init.d/proftpd. Maybe the pid file is named differently.

 

I had to restore the .pid-file for proftpd

The strange thing was that i had no pid file.
I do not know if i made a good decision;
i supercopied (scp) the backup of this file from my backup-server via SSH to the /var/run/ directory again on the production server.

The output of ls -la /var/run/proftpd.pid now is:

-rw-r--r-- 1 root root 5 2006-12-21 11:29 /var/run/proftpd.pid


Monit still gives the failure.
What can i do now?

 

When i do an: ps aux | grep ftp
The result is:

nobody 7923 0.0 0.7 4772 2292 ? Ss Dec18 0:00 proftpd: (accepting connections)
root 3141 0.0 0.2 3112 600 pts/0 S+ 19:57 0:00 grep ftp

And using FTP goes fast indeed.
However monit still now that the process Proftpd "does not excists".
I guess this is because Proftpd is not creating any pid files when the process is started again.

I really do not understand this , any one knows a solution?

 

What's in /etc/init.d/proftpd, and what's the output of

Code:

ls -la /var/run

?

 

The requested info:

Falko,

within the attachment you find the proftpd file.

The output of ls -la /var/run is:

You see, there is no proftpd.pid file

 

What's in /etc/default/proftpd? What's the output of

Code:

grep -i 'pidfile' /etc/proftpd.conf | sed -e 's/pidfile[\t ]\+//i'

?

What's the output of

Code:

ls -la /var/run/proftpd

?

 

Falko, thank you for your reply.

The output of ls -la /var/run/proftpd is:

drwxr-xr-x 2 root root 4096 2006-12-23 16:55 .
drwxr-xr-x 15 root root 4096 2006-12-21 19:51 ..

-rw-r--r-- 1 root root 32 2006-12-23 16:55 proftpd.scoreboard


And the output of

grep -i 'pidfile' /etc/proftpd.conf | sed -e 's/pidfile[\t ]\+//i'

is ... nothing !?

 

I did it

Monit can monitor proftp again.
The proftpd.pid file was missing indeed.
What i did was:

netstat -tap

tcp 0 0 *:ftp *:* LISTEN 0292/proftpd: (acce

Where i could see the process number (0292) of Proftpd.
After that i created a new /var/run/proftpd.pid file with 0292 as process number.

After that i started Proftpd again within Monit and form that moment on, Monit is monitoring Proftpd again.

I still do not know why i had to miss my /var/run/proftpd.pid, but i've noticed that i was missing it since i've updated to the last stable proftpd-version provided by Debian, which is: proftpd-common_1.2.10-15sarge3_amd64.deb
