could not bind listening IPv4 socket

I just installed Suse 12.2. I want to use VSFTPD server wit chroot for the local users.
Now when connecting to the ftp server i get error message “could not bind listening IPv4 socket”
i have listen=yes in my config file.

please see my config file:

General Settings

Use local PC time instead of GMT.


Uncomment this to enable any form of FTP write command.


Activate directory messages - messages given to remote users when they

go into a certain directory.


It is recommended that you define on your system a unique user which the

ftp server can use as a totally isolated and unprivileged user.

ftpd_banner=“Welcome to MSI-LINUX FTP service.”

You may activate the “-R” option to the builtin ls. This is disabled by

default to avoid remote users being able to cause excessive I/O on large

sites. However, some broken FTP clients such as “ncftp” and “mirror” assume

the presence of the “-R” option, so there is a strong case for enabling it.


You may specify a file of disallowed anonymous e-mail addresses. Apparently

useful for combatting certain DoS attacks.


(default follows)


If enabled, all user and group information in

directory listings will be displayed as “ftp”.


Local FTP user Settings

Uncomment this to allow local users to log in.


Default umask for local users is 077. You may wish to change this to 022,

if your users expect that (022 is used by most other ftpd’s)


Uncomment to put local users in a chroot() jail in their home directory

after login.


You may specify an explicit list of local users to chroot() to their home

directory. If chroot_local_user is YES, then this list becomes a list of

users to NOT chroot().


(default follows)


The maximum data transfer rate permitted, in bytes per second, for

local authenticated users. The default is 0 (unlimited).


#How many users do you want at the same time?

#How many logins do you allow from the same IP address at a time.


Anonymus FTP user Settings

Allow anonymous FTP?


Anonymous users will only be allowed to download files which are

world readable.


Uncomment this to allow the anonymous FTP user to upload files. This only

has an effect if the above global write enable is activated. Also, you will

obviously need to create a directory writable by the FTP user.


Default umask for anonymus users is 077. You may wish to change this to 022,

if your users expect that (022 is used by most other ftpd’s)


Uncomment this if you want the anonymous FTP user to be able to create

new directories.


Uncomment this to enable anonymus FTP users to perform other write operations

like deletion and renaming.


If you want, you can arrange for uploaded anonymous files to be owned by

a different user. Note! Using “root” for uploaded files is not



The maximum data transfer rate permitted, in bytes per second, for anonymous

authenticated users. The default is 0 (unlimited).


Log Settings

Log to the syslog daemon instead of using an logfile.


Uncomment this to log all FTP requests and responses.


Activate logging of uploads/downloads.


You may override where the log file goes if you like. The default is shown



If you want, you can have your log file in standard ftpd xferlog format.

Note: This disables the normal logging unless you enable dual_log_enable below.


You may override where the log file goes if you like. The default is shown



Enable this to have booth logfiles. Standard xferlog and vsftpd’s own style log.


Uncomment this to enable session status information in the system process listing.


Transfer Settings

Make sure PORT transfer connections originate from port 20 (ftp-data).


You may change the default value for timing out an idle session.


You may change the default value for timing out a data connection.


Enable this and the server will recognise asynchronous ABOR requests. Not

recommended for security (the code is non-trivial). Not enabling it,

however, may confuse older FTP clients.#


Turn on the below options to have the server actually do ASCII

mangling on files when in ASCII mode.

Beware that turning on ascii_download_enable enables malicious remote parties

to consume your I/O resources, by issuing the command “SIZE /big/file” in

ASCII mode.

These ASCII options are split into upload and download because you may wish

to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),

without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be

on the client anyway…


Set to NO if you want to disallow the PASV method of obtaining a data



PAM setting. Do NOT change this unless you know what you do!


Set listen=YES if you want vsftpd to run standalone


Is there a diff between VSFTPD in version 9.x and 12.2

Please advice
Thanks ina advance

The most likely cause of “could not bind” is that some other process is listening on the same port.

Dear juusi,

Welcome to the openSUSE forums.

I wonder why you ended up asking your question in the Dutch language forums, but writing your text in English. That will diminish your chance that English speaking people read it considerable.

This will be moved to the English forums, Network/Internet. Please do not post until moved.

Moved and open to posting.

Next time you post computer listing lik your configuration file above, please use CODE tags: t

And of course, please start your next thread only in the Chinese section of these forums when you do write it in Chinese :wink:

Just to add to this useful advice you can see which process is listening at which port by using the command as root :

netstat -apn

Maybe another FTP server is allready running?
