What is a Samba server in Linux?
Samba Server is the Linux implementation of SMB, or Server Message Block. It is utilized for network sharing of files and printers.
What is port number of samba?
Samba primarily uses two port numbers: TCP port 445 and UDP port 137. Port 445 is used for SMB (Server Message Block) over TCP, while port 137 is used for NetBIOS Name Service. Additionally, ports 138 and 139 are associated with NetBIOS Datagram Service and NetBIOS Session Service, respectively. These ports facilitate file sharing and printer services in a networked environment.
Samba server and ftp server difference?
Samba server is used fo sharing file and folder and directories over the network ,whether sharing between windows to Linux or vice versa,same case with the ftp but 1)ftp can provide anonymous access to the clients,that means,there is no need to have users account on ftp server 2)files first need to be downloaded from windows or Linux before viewing it,in case of samba we can direct share files. 3)in case of samba there is need of samba clients on samba server for accessing files.

port 2512 for server-to-server directed communications and port 2513 for CMC
What is a port-server?
A port is a communications endpoint on a computer, referred to as a host. A port-server operates on a specific port number of a specific port for communication.

Why is it that a server needs a fixed port number but client process can be given any random port number?
The client process needs a temporary port number. It tells the server to which port to reply (the TCP or UDP header includes information about the source and the destination port). The client, on the other hand, doesn't know in advance what port the server uses - unless the server uses a standard port number.The client process needs a temporary port number.

True or false does A web server normally assign a port number?
A Web server - or most other servers - will HAVE TO reserve a port number, to function correctly. For a Web server, this is usually port 80, but this can be changed to any other port.A Web server - or most other servers - will HAVE TO reserve a port number, to function correctly.

What ports need to be open for the client to use the FTP client software?
FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a 'data' port and a 'command' port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port. The confusion begins however, when we find that depending on the mode, the data port is not always on port 20. In active mode FTP the client connects from a random unprivileged port (N > 1023) to the FTP server's command port, port 21. Then, the client starts listening to port N+1 and sends the FTP command PORT N+1 to the FTP server. The server will then connect back to the client's specified data port from its local data port, which is port 20. From the server-side firewall's standpoint, to support active mode FTP the following communication channels need to be opened: * FTP server's port 21 from anywhere (Client initiates connection) * FTP server's port 21 to ports > 1023 (Server responds to client's control port) * FTP server's port 20 to ports > 1023 (Server initiates data connection to client's data port) * FTP server's port 20 from ports > 1023 (Client sends ACKs to server's data port) In order to resolve the issue of the server initiating the connection to the client a different method for FTP connections was developed. This was known as passive mode, or PASV, after the command used by the client to tell the server it is in passive mode. In passive mode FTP the client initiates both connections to the server, solving the problem of firewalls filtering the incoming data port connection to the client from the server. When opening an FTP connection, the client opens two random unprivileged ports locally (N > 1023 and N+1). The first port contacts the server on port 21, but instead of then issuing a PORT command and allowing the server to connect back to its data port, the client will issue the PASV command. The result of this is that the server then opens a random unprivileged port (P > 1023) and sends the PORT P command back to the client. The client then initiates the connection from port N+1 to port P on the server to transfer data. From the server-side firewall's standpoint, to support passive mode FTP the following communication channels need to be opened: * FTP server's port 21 from anywhere (Client initiates connection) * FTP server's port 21 to ports > 1023 (Server responds to client's control port) * FTP server's ports > 1023 from anywhere (Client initiates data connection to random port specified by server) * FTP server's ports > 1023 to remote ports > 1023 (Server sends ACKs (and data) to client's data port)
