Hack around a bug in pyftpdlib that rejects EPRT connection due to mismatching textual representation of the IPv6 address when the address is not in the normalized format. This happens when the control connection is mangled by Linux NAT. Signed-off-by: Jarno Rajahalme <jarno@ovn.org> Acked-by: Joe Stringer <joe@ovn.org>
