I had Samba shares working perfectly, both ways using CentOS 5. (Not sure how I did it!) When I upgraded to CentOS 6, I had a lot of problems but I managed to get it working so that I could access samba shares from Windows 7, but not the other way round. Now I'm on CentOS 7.5 and I can't get anything working at all. If I try to see Windows computers from CentOS, I get an Empty Page If I try to connect to Samba shares from Windows, I can 'see' the share, but when it asks me for a username and password, it just keeps refusing it. Here is my "sanitized" smb.conf : [global] log file = /var/log/samba/log.%m load printers = no domain master = no hosts allow = 127. 192.168.0.0/24 encrypt passwords = yes realm = xxx.mydomain.com passdb backend = tdbsam netbios name = CentOS-73 cups options = raw server string = Samba Server Version %v password server = My-DC.xxx.mydomain.com workgroup = MYOB os level = 20 printcap name = /dev/null security = ads max log size = 5 ; domain logons = yes # log files split per-machine: # enable the following line to debug: # log level =3 # maximum size of 50KB per log file, then rotate: ; id map config * : backend -tdb # Not interested in printers [homes] comment = Home Directories browseable = yes writable = yes # valid users = %S valid users = MYOB\%S [Web] comment = Web Servers browseable = yes writable = yes path = /var/www/ guest ok = no # valid users = %S valid users = MYOB\%S # Un-comment the following and create the netlogon directory for Domain Logons: #[netlogon] # comment = Network Logon Service # path = /var/lib/samba/netlogon # guest ok = no # writable = no # Un-comment the following to provide a specific roaming profile share. # The default is to use the user's home directory: [Profiles] # path = /var/lib/samba/profiles # browseable = no # guest ok = yes Before you say it - I really DON'T know what I'm doing). I still have big 'L' Plates. I work mainly with Windows. I WANT to get rid of windows, but I still don't have all the skills I need to be comfortable with it. I find Samba difficult, non-intuitive and unforgiving. The other Linux stuff, I think I'm doing OK. A bit of SIMPLE hand-holding would be nice. PLEASE!
