Today, I looked at a couple of console based RSS readers. My criteria were that
The first candidate is the most prominent one: snownews. Adding an URL of an IPv6-only site gives the result that the name does not get resolved. Opening the entry is not possible. However, with IPv4 records, everything works fine.
Conclusion: not IPv6 compatible.
The second candidate is Raggle. Here, the lists stay at (0/0) all the time too, so apparently Raggle doesn't work either.
Conclusion: not IPv6 compatible.
The third candidate in the list was
Olive. However, when
adding a feed, it responds:
500 Can't connect to blog.pas-un-geek-en-tant-que-tel.ch:80 (connect: No
route to host)
Conclusion: not IPv6 compatible.
wnews and newsbeuter are yet untested, however, better results are not expected either...
