Red Hat Bugzilla – Bug 124391
netcat lacks IPv6 functionality.
Last modified: 2007-11-30 17:10:43 EST
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? :)
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?
Not sure. Possibly somewhere like http://sed.sf.net/grabbag/misc-paolo/nc-2.0-alpha4.tar.gz
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.
I've proposed nc6 package to be included in extras. This should be replacement for current nc. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=184210
I think the nc-1.84-3.2 currently in rawhide seems to do IPv6 already.
Ok, closing this bug as rawhide.
