Alright, so I am new at FTP and i'm trying to figure everything out as I go. I have set up a FileZilla server on a home machine and have successfully forwarded the ports to the router.
My father can access the server on his machine, sign in, and do everything perfectly. He is on windows XP using the basic ftp command on the command line.
I, however, am using Linux Ubuntu 11.10. Likewise, I am just using the basic terminal ftp commands. I can connect to the server, sign in, and change directories, but many other commands, such as "ls" or "dir" will cause the following error:
421 Service not available, remote server has closed connection
My dad has confirmed not receiving this error when doing the "ls" command and can actually see the files. I receive this error when using my Ubuntu 11.10 machine.
I have been googling these issues for the past 4 hours trying to find a solution, and I have found almost nothing. I came across this thread that describes the Original poster having the exact same problem that I seem to have, however it does not look like it has been solved.
I think I have some sort of setting on my Ubuntu 11.10 machine that is inhibiting the FTP communications, but I can't find out how to solve it anywhere. Looking for some insight into this problem and thanks in advance!
