A friend suggested I take a look at the firewall. I disabled iptables to give it a try and now I can connect to the server. I made a share to an apache folder to where I can upload web files. I can connect but not login. It just won't accept my credentials.
[www]
comment = hosted web files
path = /var/www/html
available = yes
valid users = root, centman
read only = no
browsable = yes
writable = yes
I added the users to samba with
smbpasswd, something I didn't realize I had to do. I can get a directory listing of shares at the server's IP but still can't access them. It says I don't have permission.
