Lockup problem

[arromdee]

Using heimdal-ftp on Linux, I try to connect and manage to connect. Then I do a ls or get. The result: ftpd displays "502 Invalid command "EPRT|1|192.168.1.2|52727"

It then locks up and refuses to respond to the Home button or anything else until the ls command times out.

It shouldn't lock up, and also you'd probably be better off returning a response code 522 indicating that you don't support ipv6.

I am able to connect using other ftp clients that apparently don't try to use ipv6.

The EPRT command failing looks fine (it's not trying to use IPv6 here btw); heimdal-ftp appears to handle this fine, then proceeds to fallback to a PORT command, followed by a LIST command (for ls). I did get the hang you are talking about. However, a PORT command means the 3DS will connect to your client, so after turning off my firewall, it worked with no problems.

The firewall should have caused the connection to fail immediately (i.e. connection refused) but this might be yet another quirk of SOC:U, which means the whole process is hanging waiting for connect() to return. That would explain why not even the Home button works. I will change the connect() to be non-blocking which should fix the hang.

I was confused by the fact that most Google searches I get for EPRT happen when people are having trouble with ipv6. This was indeed a firewall problem (though the lockup did still happen).
