bug 6704823

http://bugs.opensolaris.org/view_bug.do?bug_id=6704823

Description:
Looks like the fix for CR 6684003 breaks sshd's ability to bind to a local
socket for X forwarding. bind() returns EADDRNOTAVAIL for every bind call to ::1
for ports 6010->6999, but never tries IPv4 localhost addresses.

Workaround:
Add lo0 for IPv6:
# ifconfig lo0 inet6 plumb up
please try -4 option for ssh. I think that should be enough, without the need of
root privileges to create a loopback with IPv6 address.

Well I tried both and:

if I do ssh -4vAX remotehost
I do not get the display
if on the remote host I touch hostname6.lo0 I get the remote display.
I wonder why the -4 works in some cases and not others?

If you have a support contract open a case with Sun, there is a
IDR available which solves the issue.

Frank
