I'm fairly new to ubuntu and have been asked to figure out why the samba 3 shares on a ubuntu 10.x server have become inaccessible. Here are the details: Office staff suddenly cannot access their samba shares from their mac osx clients. They can connect to the server, it accepts password, shows the available shares, but when one is selected (any of them except netlogon), user gets the message "Connection failed. There was an error connecting to the server "192.168.10.11" Check the server name or IP address, and then try again." The samba log file only says: [2012/06/29 07:12:15, 0] smbd/service.c:988(make_connection_snum) canonicalize_connect_path failed for service shared, path /home/shared However, root CAN connect to any of the shares successfully from the same client machines. Smb.conf has not changed since the problem started, and the folder permissions look correct. Samba has been restarted. The samba documentation I find online shows access can be given to clients in the smb.conf file using "valid users" variable, but this is not how this particular implementation has been configured. Where else should I look to find the source of the problem. Are there other methods to give access to samba shares than using the smb.conf options? Thanks Richard
