  30. Network Printer Server Software 1. DISCOVER 2. OFFER DHCP Client 3. REQUEST DHCP Server 4. ACK DHCP (Dynamic Host Configuration Protocol) DHCP is a communication protocol enabling network administrators to centrally manage and to automate the assignment of IP addresses in a network. In an IP network, each device needs a unique IP address. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a device is plugged into a different place in the network.

  31. Network Printer Server Software DNS (Domain Name System) DNS is used for registration of domain names and provides Host names to an IP address resolution service. For printer devices, DNS may be utilized for printer domain name registration, so that print server clients may refer to the printer by its host name rather than by its IP address. Even though a printer’s IP address is changed, all clients can operate this printer without reconfiguration. Addressing to a printer device by IP address is not convenient and may often go stale if an IP address to a device is assigned dynamically via a DHCP server. If the DHCP server can provide information about a printer’s changing IP address to the DNS server automatically, user convenience is increased. The printer’s name will be used as its DNS name.

  32. Network Printer Server Software WINS (Windows Internet Name Service) WINS proprietary Microsoft name resolution service WINS servers maintain computer names (NetBIOS names) and IP addresses automatically. WINS is used to dynamically provide an NT-based domain name server with the names and IP addresses of Windows computers.

  33. Network Printer Server Software SLP (Service Location Protocol) SLP (Service Location Protocol) is an Internet standard network protocol that provides a framework to allow networking applications to discover the existence, location, and configuration of networked services with human readable text string. Character Encoding : UTF-8 (SLP v2) Using TCP/UDP port : 427. SLP Security : IPSec. SLP Multicast Address : 1. 239.255.255.253 : RFC2608 2. 224.0.1.127 : Requested By Xerox (Xerox Device Discovery) 3. In the absence of Multicast support, Broadcast may be used. SLP is used for detecting network printer server in Syncthru WAS

  34. Network Printer Server Software Multicast DNS - Bonjour (Old name : Rendezvous) Automatic discovery of computers, devices, and services on IP networks Automatically find each other without the need to enter IP (Internet Protocol) addresses or configure DNS (Domain Name Service) servers Listens for multicast DNS queries on TCP/IP port 5353 Sends responses for Multicast DNS queries to multicast address 224.0.0.251 DNS domain: “< Host Name > + .local” Services Zero Configuration Networking Multicast DNS DNS Service Discovery http://www.apple.com/macosx/features/bonjour/ Bonjour for Windows - Bonjour is useful for detecting network printer server on internet explore and add network printer port.

  35. Network Printer Server Software • SNMP (Simple Network Management Protocol) • SNMP facilitates the exchange of management information between network devices. It enables network administrators to remotely monitor and configure network devices, find and solve network problems, and plan for network growth. • Network devices are monitored and controlled using four basic SNMP commands: • • read: is used by a Network Management server to monitor network devices. The server examines different variables that are maintained by the devices. • • write: is used by a Network Management server to control managed devices. The server changes the values of variables stored within the devices. • • trap: is used by network devices to asynchronously report events to a Network Management server. When certain types of events occur, a device sends a trap to the specified server.

  36. Network Printer Server Software SNMPv3 (Simple Network Management Protocol - A Security Enhancement for SNMP ) • SNMPv3 • = SNMPv2 + administration + security • SWS -> Network Settings -> SNMPv3 1. User Name : • SNMPv3 Account user name • 2. Authentication Password : • a 16-byte hexadecimal value • for authenticating the SNMP packet • contents using the MD5 algorithm. • 3. Privacy Password : a 16-byte hexadecimal value for encrypting the data portion of the SNMP packet using the DES algorithm.

  37. Network Printer Server Software Web Server HTTP (Hypertext Transfer Protocol ) • HTTP is an application layer protocol for distributed, collaborative, hypermedia information systems. • The Samsung Network Printer has a built-in web server, SyncThru Web Service. You can configure and manage your network print server through SyncThru Web Service using HTTP over TCP/IP. • Used in IPP Protocol IP: 10.240.9.170 http://10.240.9.170 User

  38. Network Printer Server Software 웹 서버 HTTPS (Secure Hypertext Transfer Protocol ) • Secure, encrypted Web-based communication is provided through the Secure HTTP (HTTPS) protocol. • SWS -> Machine Settings -> Secure Web • To support the use of HTTPS communications, an certificate must be installed. • HTTPS TCP Port Number is 443. • HTTPS URL uses 'https://‘ instead of 'https://' IP: 10.240.9.170 https://10.240.9.170 사용자

  39. Network Printer Server Software HTTPS Configuration - Self Certificate • SWS -> Machine Settings -> Secure Web • Create New Certificate (Self Certificate) • Input information and create certificate • Enable Web Security • Accept certificate from device and use HTTPs
