Problems accessing FTP

[markross]

I am leasing a dedicated server which comes pre-installed with Fedora Core 4 & Plesk 8. I am hosting several domains on the server. However recently I have been unable to access any of my sites via FTP. My knowledge of linux is pretty limited, but I am guessing it is something to do with the firewall setup.

I have logged in using putty and have done a port scan locally and port 21 appears to be open. However when I do a port scan remotely is says that port 21 is closed. I have the Plesk firewall module installed with port 21 set to "Allow incoming from all".

I have no idea where to begin fixing this so if anyone could give me any pointers that would be great.

Thanks

Mark

restart xinetd (/etc/init.d/xinetd restart)

or check /etc/proftpd.conf for:
# Enable PAM authentication
AuthPAM on
AuthPAMConfig proftpd

and try to disable PAM (AuthPAM off)

also be sure that an AuthGroupFile has been assigned.

Also check if the values are like the below:

<Global>
DefaultRoot ~ psacln
AllowOverwrite on
</Global>

and:

<Directory /home/httpd/vhosts>
GroupOwner psacln
</Directory>

Thanks for the reply - I have checked all the above and it is all as it should be. It isn't a login problem, I can't even connect to the server which makes me think it might be to do with a firewall.

If I do a port scan on the local server I get the following:

PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
106/tcp open pop3pw
110/tcp open pop3
143/tcp open imap
443/tcp open https
465/tcp open smtps
953/tcp open rndc
993/tcp open imaps
995/tcp open pop3s
5432/tcp open postgres

If I do a port scan remotely I get this:

PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
80/tcp open http
110/tcp open pop3
443/tcp open https
465/tcp open smtps
995/tcp open pop3s
8443/tcp open https-alt

As you can see port 21 is showing up a open on the local scan but not on the remote one. This is also backed up by the fact that I can log in to FTP via SSH on the local server. However the Plesk Firewall module is showing port 21 as open so I am wondering what has happened to make it inaccessible when it was fine until about a week ago.

I've just tested the Plesk firewall module by trying to open a random port (1234) and then port scanning that port, and the port is still showing up as closed. So unless I am missing something the Plesk firewall module isn't working either.

I am having a similar problem as well. Since I am not that technical I don't know if it is the same problem.

I am able to login to my ftp server, but i get an error. Here are the details from FileZilla

did you test "active mode" in your ftp-browser?

This problem is different to mine as I cannot even get a connection to my FTP remotely. Hence switching to active mode doesnt make any difference.

I am also getting this error, though i coukld see the backup utility is succesfully uploading the psa backup.
-------------------------
Backup error. Can not upload backup file psa-7.6-NS8.<Servername>-2006.08.08.psa to FTP server.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
---------------------

Any idea getting this error despite file is being uploded to remote ftp erver.

I finally got the FTP server working, but I didn't do anything to get it to work. So I couldn't help you with your problem. I would recommend emailing support, they are good at troubleshooting problems.
