fsftpd broken

[johnh10000]

Now I run 2 ftp servers on my network. tux on the usual ports 20-21
and tux2 on 90-91. This has been working for months.

When I TRY to log into tux, from tux2 (I get clues that way) I get

johnh10000@tux2:~$ ftp tux.isa-geek.org
Connected to tux.isa-geek.org.
220 Welcome to blah FTP service.

ftp> ls
500 Illegal PORT command.
ftp: bind: Address already in use
ftp> quit
221 Goodbye.
johnh10000@tux2:~$

ANd of course no dir list.

Now I haven't changed the confog, so I am a tad confused.

Any kind soul will help me?

in addition from tux2 which is on the loacl net I get this now:
[2]+ Stopped ftp -p tux.isa-geek.org 21
johnh10000@tux2:~$ ftp -p tux.isa-geek.org 21

Oh it works just fine on tux, just know where else

An update gang

When I change tux ftp port to 90-91 it works. It just don't work at 20-21
Plain weird.
