Find all FTP packages

[Kingfisher]

Hello ,
I installed pure-ftpd and put a virtual user until this point there was no error. By cons when I decided to start the server it gave me an error

debian: / etc # pure-ftpd
Unable to start a standalone server: Address already in use

Then with the use of the command USIS it said there was a problem to use this since I already tried to install another FTP without success. So I think the ftp address is already used or the process and that pure-ftpd can not boot. How to know that ftp work? order to remove FTP. I was looking for whether that prevents pure-ftpd start otherwise there would not be a log somewhere. I tried the following

debian: / etc # dpkg - list '* ftp'

I do not know I am right or not? or am I completely off the plate ? Thanks in advance.

Hi
You can see what process is listening on port 21 (ftp) with the following command.

# lsof -i: 21

To issue this command first you have to be the root user. Think this may help you. If any problem do post back.

Hi
As you said I issue the following command

# lsof -i: 21

This was the result I got

 debian: / etc # lsof-i: 21
CMD PID USER SIZE NODE
inetd 1584 root 4u IPv4 3254 TCP *: ftp

Please not that port 21 from my router is on open. Now, any advice on this.

Hello
FTP service is run by the super daemon inetd. You can look in / etc / inetd.conf if this service is uncommented. To disable it you can put it in comment and restart the inetd for the changes to take effect. Then you run again lsof command to make sure that port 21 is no longer used. Any more problems do post back.

Hi
Output of / etc / inetd.conf:

debian: / etc # vi / etc / inetd.conf

ftp stream tcp nowait root / usr / sbin / tcpd / usr / sbin / proftpd

I did not find the line uncommented. I have not tried to comment the line and restart it. I think there is a risk in doing that. Any advice.

Hello

I have not tried to comment the line and restart it. I think there is a risk in doing that.

Yes you can surely comment the line. There is no risk in that. You have already installed proftpd as ftp service so if you want to use pure-ftpd proftpd must be disabled. This will surely work. Try it.

Hi
There is no problem now when I issue this command.

# lsof-i: 21

Every thing is working fine now, and it is giving the desired result what I want. Thanks for your help.
