Samba Interview Questions & Answers part 1
Q: – Which SELinux security context used for SAMBA ?
Q: – what is nmbd daemon?
This daemon handles all name registration and resolution requests. It is the primary vehicle involved in network browsing. It handles all UDP-based protocols. The nmbd daemon should be the first command started as part of the Samba startup process.
Q: – What is smdb daemon?
This daemon handles all TCP/IP-based connection services for file- and print-based operations. It also manages local authentication. It should be started immediately following the startup of nmbd.
Q: – My clients are getting the error message that the Disk is Full when trying to print to my Samba server, but there is plenty of space. What is the problem?
If smbd is unable to write the spooled file to the directory defined by the path parameter for a printer if the write permission were denied, for example it would respond to the client with the message, Disk is Full. Samba will also return this error message if the amount of free disk space in the spool directory has fallen below the value specified by the min print space parameter.
The Windows client is attempting to use encrypted passwords. However, the Samba server is configured to support only clear-text passwords. You should either enable encrypted passwords on the server or enable clear-text passwords on the Windows client.
Q: – On which ports SAMBA server works ?
– UDP port 137 for netbios-ns, the NETBIOS Name Service
– UDP port 138 for netbios-dgm, the NETBIOS Datagram Service
– TCP port 139 for netbios-ssn, the NETBIOS session service
– TCP port 445 for microsoft-ds, the Microsoft Domain Service
Q: – Why is security = domain better than security = server?
There are three reasons why security = domain is better. The first is because this method enables the Samba server to participate in domain trust relationships. This is impossible with server-level security. The second reason is that, under server-level security, each smbd process must keep an open connection with the authentication server. This can drain a Windows NT PDC quickly. Under domain-level security, this connection is maintained only long enough to perform the validation, thus conserving valuable resources. The final reason is that, as a domain member, the Samba server has access to much more information about user accounts, which can be used to automate the creation and deletion of user accounts upon demand.
Q: – What is winbindd daemon?
This daemon should be started when Samba is a member of a Windows NT4 or ADS domain. It is also needed when Samba has trust relationships with another domain. The winbindd daemon will check the smb.conf file for the presence of the idmap uid and idmap gid parameters. If they are found, winbindd will use the values specified for UID and GID allocation. If these parameters are not specified, winbindd will start but it will not be able to allocate UIDs or GIDs.
