Proftpd directory listing error on Docker container

Question

I have been using proftpd on Ubuntu inside a Docker container. It logs in successfully but failed to get directory listing.

Here is the screenshot of Filezilla

And screenshot of Proftpd log file

Any help?

Answer 1

The problem is the proftpd advertises the internal ip address 172.... so the client cannot connect to it.

You can solve this by setting (in the proftpd.conf)

MasqueradeAddress externalIP

or by running the conatiner using:

docker run --net=host  .....

This option uses the host ip network so the passive mode will work fine.
