Hi,
My father recently setup a new 7.0-Release system for some web
development. I use ssh to login remotely. I've normally not had any
trouble configuring authentication through public key encryption using
ssh-keygen and such. I have for myself a id_rsa.pub and an id_rsa key pair
that I use for this purpose.
Normally, I just copy, via scp, the file id_rsa.pub to my
~/.ssh/authorized_keys file on the remote host and the next time I attempt a
login all is well. That is, I don't have to enter my password. However, on
my Dad's new machine, this isn't the case. I still have to enter the
password.
Now, I've looked through his /etc/ssh/sshd_config file and nothing in
there looks odd, or different, from other remote hosts I do this on. So,
I'm embedding a copy/paste of an ssh login session on my father's host using
-v -v to ssh:
[/usr/home/andy/MCH]
-> ssh -v -v malumgat

debug2: we sent a publickey packet, wait for reply

It seems OpenSSH (on your dad's box) hasn't recognized your private key, so
how about checking permissions of ~/.ssh/authorized_keys and ~/.ssh on his
box. Or how about enabling verbose logging on his box, using 'LogLevel'
parameter in sshd_config.

The permissions on the machine where it works:
[www:/home/afalanga]
-> ls -la .ssh/
total 6
drwxr-xr-x 2 afalanga staff 512 Sep 28 03:33 .
drwxr-xr-x 3 afalanga staff 512 Oct 29 08:31 ..
-rw-r--r-- 1 afalanga staff 393 Sep 28 03:33 authorized_keys
The permissions on the machine where it doesn't work:
[andy@mch ~]$ ls -la .ssh/
total 6
drwxrwxr-x 2 andy wheel 512 Oct 10 04:30 .
drwxr-xr-x 4 andy wheel 512 Oct 31 06:30 ..
-rw-r--r-- 1 andy wheel 393 Oct 28 10:01 authorized_keys
I see a difference in that the directory on the machine where it
doesn't work is writable to the group, but on the machine where it
does work the directory isn't writable. Other than that, the
permissions don't look different, do they?
