Here, 83.250.192.69 is the IP-number of my machine. I don't know what the
|1| and |52641| parts mean.

1 means IPv4 (it would be 2 for IPv6), and 52641 is the port number that
the client is listening for data connections on.

I'm not sure why it's doing this when it has already negotiated passive
mode. Maybe it encountered an error trying to connect to the server on
port 55291, so it's trying active mode as a fallback.

Can you run a sniffer and see if it's trying to connect to 55291?

Then you will have to instruct me. :-) Though mentioned before, ncftp on
the same site does not result in the EPRT command being issued, nor does
it happens with ftp on other sites. So there is something specific in the
combination of /usr/bin/ftp interacting with this particular site.
