Hi,
I appear to have broken the samba service/daemon. I suspect I know what is wrong, but I dont know how to confirm it.
In any case, i'll explain the issue, then the probable cause. I looked at my servers status today and saw the server was not running, i refreshed the status, then attempted to start it. nada. I confirmed the service was indeed own by attempting to access the network share, and it is indeed down.
Now, I believe this was caused by some manual changes I made to samba.conf. As this box will someday be used to VPN into my network, I think it advisable to secure it as much as possible. I ran a vulnerability scan against the box, and found several samba related vulnerabilities, and i proceeded to fix them. If I remember correctly, the fix involved restricting anonymous CIFS viewing. The added strings were:
guest account = noaccount (the suggested was nobody, but only if user "nobody" did not exist in /etc/passwd, but there is a nobody user in fedora 14)
restrict anonymous = 1 (should this be 2? when i performed a google search, i found a bunch of references to 2 breaking AD)
server signing = auto
server signing = mandatory
