Description Andrew Schultz 2008-05-21 05:12:16 UTC
Description of problem:
After upgrading to Fedora9, I get the following whenever I try to connect to a
server (which supports hostbased authentication), I get:

cannot get sockname for fd
ssh_keysign: no reply
key_sign failed

hostbased authentication fails.  Adding some print statements to the source, it
seems that getsockname (called from get_socket_address) fails with EBADF (it
thinks the socket is bogus).  "setenforce 0" didn't help.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. ssh host (remote host needs to support hostbased auth)
Actual results:
hostbased auth fails

Expected results:
hostbased auth works

yum isn't finding an update from the updates-testing repo.  I'm not seeing a new

Yes, the update has not yet been pushed into the repository, hopefully later

have to update pam from the last F9 build as well.
