I've been trying to reproduce the following bug from FOR-RELEASE:

My DNS also issues an IPV6 address, but the ftp program I use (BSD ftp on
a Red Hat box) fails silently on IPV6 without issuing a "No route to host"
message:
ftp> open ftp.nluug.nl
Trying 2001:610:1:80aa:192:87:102:36...
Trying 192.87.102.36...
Connected to ftp.nluug.nl (192.87.102.36).
Does anyone know a simple way to reproduce this bug?
In any case, could it be fixed by replacing "No route to host" with "No
route to host\n[^T]" in ange-ftp-gateway-fatal-msgs, to distinguish
between "No route to host\nTrying..." and a real error?
