ERROR:> Failed to establish data socket

[afgs]

I have setup vsftpd on my Linux machine. I have enabled local users to login in the /etc/vsftp.conf file. I can succesfully login, but can't connect to the data socket. (see below). What haven't I done yet.

I have checked the files in /home/alexg are all owned by that user. The permissions on the directory is drwxr-xr-x

Do you have firewall activated? This error means that you cannot establish data connection. Ftp uses two connections - one for commands (to port 21), one for data transfers (port 20 while using active connection, random port while using passive connection). The second difference between active and passive is that in passive mode the connection originates at USER end, in active mode at SERVER end. So, check your firewall status/logs.
