Operating Systems HP-UX Unable To Perform A "Passwordless" SSH Login To A Server Post 302515674 by Rob Sandifer on Wednesday 20th of April 2011 04:05:14 PM

Okay, I finally discovered what the problem was and fixed it. I would like to share the solution with the members of this thread because, even though the problem is now fixed, there was something in the solution
that I am not understanding (detailed down below).

Upon reading the system log (/var/adm/log/syslog/syslog.log), it reads as follows:

Apr 20 10:33:30 fyman00 sshd[25874]: Authentication refused: bad ownership or modes for directory /root

That, of course, got me in the ballpark...

I then looked at the permissions on /

# ls -al /
drwxrwxrwx 5 root bin 96 Apr 16 14:55 root

At that point, I knew the problem was going to be either "root bin" (improper owner) or "drwxrwxrwx" (incorrect permissions) or a
combination of both on the file /root

To determine which was the culprit, I corrected each one separately and then tested separately.

I then set the ownership to the correct setting: "root root". Retested and still could not achieve a successful passwordless (publickey) login. I then changed the mode to drwxr-xr-x I retested and then, you guessed it, I was able to successfully achieve a passwordless login. The final correction to /root reads as follows:

drwxr-xr-x 5 root root 96 Apr 16 14:55 root

Okay, here is the part that I do not understand: Why, after changing the mode from a LESS restrictive setting (drwxrwxrwx) to a MORE restrictive setting (drwxr-xr-x), why was I then allowed to finally authenticate correctly? This seems so counterintuitve... I'm quite certain that I am overlooking something rather basic...

Any ideas so I can finally put this one to bed? Thanks!

Rob S.
