Re: [sshfs] Error "Connection Reset By Peer" on pam_mount+sshfs (Fedora Core 6)

After a few days studying the output from strace, I now see quite 
clearly that the ssh child is not getting the password correctly.

I see this because the strace shows "Password incorrect" messages, and 
these happen immediately, three times (with no waiting time) and this 
only happens on a ssh logon when the password is blank. A debug on the 
server side shows me that there are three attempts to authenticate but 
none with success (and all the attempts within a few milliseconds period).

I should think about a pam.d configuration problem but, on the other 
hand, using cifs instead of sshfs works perfectly, so it seems like the 
password is being delivered ok to CIFS. Why then is ssh not 
authenticating with the very same password?

I hope you can help me to understand where is the password being lost on 
its handling to sshfs.

To remind you, the user can mount his home himself with mount.fuse (via 
sshfs), so no privilege problems here. And a direct ssh or sftp login 
works perfectly.

There are other errors in my strace like (/dev/tty not found) but I 
don't know whether they are to blame or not. I think it's just trying to 
write an error to the output but no output is available. Of course, that 
device exists and has perms 666.

Thanks in advance for replies.
