proftpd doesn't (re)start

Hi,
I realized that proFTPd isn't running and as restarting ftp didn't workout I restarted the server itself.

In the /var/log/syslog I found the following entries:

Code: Select all

May  4 21:21:28 bubba proftpd[1201]: bubba - Failed binding to 0.0.0.0, port 21: Address already in use
May  4 21:21:28 bubba proftpd[1201]: bubba - Check the ServerType directive to ensure you are configured correctly.

So whats the problem here?

It startet at the time, when I did an upgrade which I started from the webinterface that didn't finish - I needed to do a "dpkg --configure -a" to finalize it. It also upgraded proftpd (current release on my box is: 1.2.10-15). Are there any problems with this release?

Update:
I removed proftpd, which of also removed other packages including bubba package. Then I reinstalled the bubba package which also brought proftpd and proftpd-common along with it. I selected the package maintainers version of the config file for proftpd and now its up & running again.

Remaining 2 questions:
1) Is 1.2.10-15 the bubba standard version for proftpd?
2) Should proftpd be set as servertype "inetd" or "standalone"?

Sorry for hijacking this thread...

Related to this, does anyone know how to find out what process is owning a particular listening socket in linux?

I work in tech support and I see these issues often. On windows I use the excellent tcpview from sysinternals to verify the issue and find out what process is hogging the port.

How can I do the same on a unix-like system?

Thanks in advance

use

Code: Select all

sudo netstat -anp

it will show you states of connections and which PID/process is responsible for it.

okay - and now back to the questions:

1) Is 1.2.10-15 the bubba standard version for proftpd?
2) Should proftpd be set as servertype "inetd" or "standalone"?

Hi dsp76,

1) yes
2) I'd run it as standalone, but both will work...

Hi bjorn,

sudo netstat -anp

As simple as adding -p

Thanks!
