[bug-inetutils] [PATCH 2/4] FTP client is migrating to IPv6.

[Mats Erik Andersson]

Dear all,

time for the second installment, now making the
FTP client speak also IPv6.

I forgot to state last time, that the default
setting `doepsv4 = 0` is due to the fact that
one well-known FTP server fails to correctly
handle an IPv4-only client asking for EPRT,
when the server itself is configured to allow
IPv6. That other server does not handle mapped
addresses correctly, configuring the data channel
on an IPv6 socket, inspite of the client asking
for IPv4. Had I not discovered this, the setting
`doepsv4 = 1` would have been my choice.

Installment three will implement client internal
commands `ipv4`, `ipv6`, and `ipany`, thus allowing
full control of target addressing. This part is left
out of the present patch in order to simplify checking.

The fourth and last patch will update the Texinfo
source with all the new capacities.


Best regards,
  Mats
