How do I know if Samba is running? The easier way is to check with your package manager. If that doesn't work, you just need to type samba --version and if it's in your path it should work.

Qifeng Hommel Pundit. How do I test Samba? How to Verify the Installation and Configuration of Samba. Test the smb. If the global zone is being used for Samba. If winbind is used, start and test winbind. Start and test winbind.

Start and test Samba. Start Samba. Stop the smbd, nmbd, and winbindd daemons. Unmount the highly available local file system. Remove the logical host. Note this is not run with sudo. It will prompt once for the previous samba password and twice for the new one. Samba itself is secure in the fact that it encrypts passwords can be set to use cleartext but that would be bad but by default data is not encrypted. NFS uses the host-based authentication system. To query the network for Samba servers, use the findsmb command.

The easier way is to check with your package manager. Encrypted passwords are, of course, more secure. A non-encrypted password can be easily read with a packet sniffing program, such as the modified tcpdump program for Samba that we used in Chapter 3, Configuring Windows Clients.

Whether passwords are encrypted depends on the operating system that the client is using to connect to the Samba server. Table 6. If your client is not Windows, check the system documentation to see if SMB passwords are encrypted. There are actually two different encryption methods used: one for Windows 95 and 98 clients that reuses Microsoft's LAN Manager encryption style, and a separate one for Windows NT clients and servers.

Windows 95 and 98 use an older encryption system inherited from the LAN Manager network software, while Windows NT clients and servers use a newer encryption system.

If encrypted passwords are supported, Samba stores the encrypted passwords in a file called smbpasswd. At the same time, the client stores an encrypted version of a user's password on its own system. The plaintext password is never stored on either system. Each system encrypts the password automatically using a known algorithm when the password is set or changed. When a client requests a connection to an SMB server that supports encrypted passwords such as Samba or Windows NT , the two computers undergo the following negotiations:.

The client attempts to negotiate a protocol with the server. The server responds with a protocol and indicates that it supports encrypted passwords. At this time, it sends back a randomly-generated 8-byte challenge string.

The client uses the challenge string as a key to encrypt its already encrypted password using an algorithm predefined by the negotiated protocol. It then sends the result to the server. The server does the same thing with the encrypted password stored in its database.

If the results match, the passwords are equivalent and the user is authenticated. Note that even though the original passwords are not involved in the authentication process, you need to be very careful that the encrypted passwords located inside of the smbpasswd file are guarded from unauthorized users.

If they are compromised, an unauthorized user can break into the system by replaying the steps of the previous algorithm. The encrypted passwords are just as sensitive as the plaintext passwords - this is known as plaintext-equivalent data in the cryptography world.

Of course, you should also ensure that the clients safeguard their plaintext-equivalent passwords as well. You can configure Samba to accept encrypted passwords with the following global additions to smb. Note that we explicitly name the location of the Samba password file:.

Samba, however, will not accept any users until the smbpasswd file has been initialized. While Unix authentication has been in use for decades, including the use of telnet and rlogin access across the Internet, it embodies well-known security risks. Plaintext passwords are sent over the Internet and can be retrieved from TCP packets by malicious snoopers. In order to do this, you must modify the Windows registry by installing two files on each system. You can perform this installation by copying the appropriate.

Incidentally, the Windows After you reboot the machine, the client will not encrypt its hashed passwords before sending them to the server. This means that the plaintext-equivalent passwords can been seen in the TCP packets that are broadcast across the network. Again, we encourage you not to do this unless you are absolutely sure that your network is secure.

If passwords are not encrypted, you can indicate as much in your Samba configuration file:. All other users should not be able to read from the directory at all.

In addition, the file should have all access closed off to all users except for root. Before you can use encrypted passwords, you will need to create an entry for each Unix user in the smbpasswd file. The structure of the file is somewhat similar to a Unix passwd file, but has different fields. Figure 6. This is the username of the account. It is taken directly from the system password file. This is the user ID of the account.

Like the username, it is taken directly from the system password file and must match the user it represents there. This is a bit hexadecimal sequence that represents the password Windows 95 and 98 clients will use. It is derived by encrypting the string KGS! Anyone can access the share with no password.

On the other hand, if the password has been disabled, it will consist of 32 X characters.
