Hi, Anybody help me out to understand the source code.I given the information what i understood. Please correct me if I am wrong.
Planner sends the request to the client(amandad)to get the estimation of the backup data. planner module is present at server side and amandad service is present at the client side. Suppose if i am taking the backup only for the server means DLE has an entry with the server address. In this scenario the server act as a client, server bind the ipaddress as a noop,0.0.0.0 and client bind the ipaddress and port no as 120.120.120.120:10080. {My server address is 120.120.120.120). Client has the module noop , which provides the compatibility with the server module. Client has the module Sendsize which send the estimated size information to the server. Planner sends this information to the driver which initiates the dumper and taper process. Client has the sendbackup module , which bind the IP address has 120.120.120.120 with the port no as TCP unprivileged ports and make the connection with the dumper has the IP address as 0.0.0.0 with the privileged port no. Sendbackup connects three port nos which has to send the backup image, message and index. Runtar, Rundump module performs the backup according the program configured as tar ,dump respectively Sendbackup module send the information to the dumper through the sockets. Dumper send the data to the holding disk. Taper reads the data from the holding disk to the taper. Taper writes the data to the tape. Here socket connection is not required between the dumper and taper. But if the holding disk is too small, then the dumper directly send the data to the taper, Which uses the socket connection through the TCP. Because the taper and dumper is present in the single module. Please provide what IP address and port no is used to connect between the taper and dumper. I have one more question: Suppose if I want to eliminate the sockets for the security reason (because of the port no) How can I approach . Please provide me the details.
