Description David Woodhouse 2004-05-26 06:22:02 EDT
Configuring ssh to use 'ProxyCommand ssh <someipv6box> nc %h %p' for
connecting to IPv6-only hosts fails. It seems nc doesn't support IPv6. 

Even nc 2.0-alpha2 is fairly odd. It _does_ support IPv6 but you have
to explicitly ask it to; it doesn't just look up the hostname it's
given and use RFC3484 ordering (which glibc will basically do _for_ it).

Got a patch? :)
Comment 2 Radek Vokal 2005-04-11 07:23:20 EDT
I've pushed new OpenBSD netcat into rawhide. Anyway it probably won't fix this
issue. You still have to specify whether you're using IPv6 or IPv4 mode.. 

David, where did you get nc-2.0 from? 
Comment 3 David Woodhouse 2005-04-11 07:51:38 EDT
Not sure. Possibly somewhere like 
Comment 4 Matthew Miller 2005-04-26 11:37:03 EDT
Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
Comment 5 Radek Vokal 2006-03-07 07:37:33 EST
I've proposed nc6 package to be included in extras. This should be replacement
for current nc. 

Comment 6 David Woodhouse 2006-03-07 08:16:15 EST
I think the nc-1.84-3.2 currently in rawhide seems to do IPv6 already.
Comment 7 Radek Vokal 2006-03-07 10:02:14 EST
Ok, closing this bug as rawhide.
