Not that I need to have it up and running, but since I was new to the
Mystic, I thought I'd play with things to see how things worked. One of
the things I noticed was the FTP doesn't quite act right when I tried to
have it run on ports 2121 or 8021. It fails to give me a directory
listing. It sort of just hangs there. Yet if I configure it for 21 or
even 50 for the port, I do get a directory listing. I'm running under a
Linux OS. I'm not having any issue running any of the other services on
any port number of my choice. Is this a known issue with the FTP service
under Linux?

In short, not that I am aware of. I'm running Windows so can try and test
this out also just to see if there's anything to this using that OS.

Thanks for taking a look. It you don't find anything, no worries. It could easily just be something on the Linux side that is wrong.

Just curious, are you accessing your ftp server through a firewall wihh
NAT?

FTP servers only use port 21 for the control connection, any transfers
like directory listings or file transfers are done over random data
ports.

If you're using PASSIVE mode, your computer makes the connection to the
ftp server, normal mode, the ftp server connects to you.

This can cause issues with firewalls and NAT, so usually they have an 'ftp-proxy' built in, which I believe monitors connections on port 21 and forwards ports appropriately, if you're not using port 21 you might need
to adjust yout firewalls ftp proxy to monitor the correct port.

Sure thing :)

I'll just have a play this weekend... and let you know

No NAT. The system is running on a VPS that I have.

FTP takes significant work on your firewalls to properly work in both passive and non-passive modes. Its not the most secure thing ever, unfortunately.

You may have a software firewall or a router preventing traffic (and for good reason).
