    trying to use ssh and get Permission denied (publickey)


    Having been using this since about August, but off it a couple of months. I don't think I've created any new keys, As I'm kind of reluctant to do so. However I'm going back into the hospital for a few days and need the ssh functionality again to be operational. I've attempted to use it as before but get the following:

    I am suing a backport of "3.14-0.bpo.2-amd64" on this laptop, but the other machine gets updated everytime a new one comes out. I will attempt to see that this is updated and try again. I am not optimistic.

    Code:
    $ ssh -l jkwilborn 192.168.1.105
    Debian GNU/Linux 7
    Permission denied (publickey).
    jack@debian-laptop:~$ ssh -vl jkwilborn 192.168.1.105

    I had used this many times while in the hospital previously, but now it's complaining. Reading the output seems to indicate that it has OKd the 'key' yet goes on into an area I don't seem to understand. Why did it say it was ok then attempt to continue other validations on the code?

    Any help or explanation of this would be great news, but I do need it!

    I can't think of anything that has changed as I used it when I returned home also. It has been shelved for less than three months!

    Thanks...

    Check that /etc/ssh/sshd_config has "HostbasedAuthentication" set to yes.

    Gregm:... Thanks, that was set to no, so I changed it. I will test it out at a later time. I'm getting ready to get my knee replaced today..

    Thanks

    Gregm: Thanks, I've survived the left one done on the 14 Aug, now this one. It should be the end though. I hope I don't lose any more joints!

    Thanks

    Jack
