Well Known TCP and UDP Ports Used by Apple Software Products
Well known TCP and UDP ports used by Apple Languages English software products Symptoms Learn more about TCP and UDP ports used by Apple products, such as OS X, OS X Server, Apple Remote Desktop, and iCloud. Many of these are referred to as "well known" industry standard ports. Resolution About this table The Service or Protocol Name column lists services registered with the Internet Assigned Numbers Authority (http://www.iana.org/), except where noted as "unregistered use." The names of Apple products that use these services or protocols appear in the Used By/Additional Information column. The RFC column lists the number of the Request For Comment document that defines the particular service or protocol, which may be used for reference. RFC documents are maintained by RFC Editor (http://www.rfc- editor.org/). If multiple RFCs define a protocol, there may only be one listed here. This article is updated periodically and contains information that is available at time of publication. This document is intended as a quick reference and should not be regarded as comprehensive. Apple products listed in the table are the most commonly used examples, not a comprehensive list. For more information, review the Notes below the table. Tip: Some services may use two or more ports. It is recommend that once you've found an instance of a product in this list, search on the name (Command-F) and then repeat (Command-G) to locate all occurrences of the product. For example, VPN service may use up to four diferent ports: 500, 1701, 1723, and 4500. -

951 John Gilmore (Sun Microsystems) September 1985
Network Working Group Bill Croft (Stanford University) Request for Comments: 951 John Gilmore (Sun Microsystems) September 1985 BOOTSTRAP PROTOCOL (BOOTP) 1. Status of this Memo This RFC suggests a proposed protocol for the ARPA-Internet community, and requests discussion and suggestions for improvements. Distribution of this memo is unlimited. 2. Overview This RFC describes an IP/UDP bootstrap protocol (BOOTP) which allows a diskless client machine to discover its own IP address, the address of a server host, and the name of a file to be loaded into memory and executed. The bootstrap operation can be thought of as consisting of TWO PHASES. This RFC describes the first phase, which could be labeled 'address determination and bootfile selection'. After this address and filename information is obtained, control passes to the second phase of the bootstrap where a file transfer occurs. The file transfer will typically use the TFTP protocol [9], since it is intended that both phases reside in PROM on the client. However BOOTP could also work with other protocols such as SFTP [3] or FTP [6]. We suggest that the client's PROM software provide a way to do a complete bootstrap without 'user' interaction. This is the type of boot that would occur during an unattended power-up. A mechanism should be provided for the user to manually supply the necessary address and filename information to bypass the BOOTP protocol and enter the file transfer phase directly. If non-volatile storage is available, we suggest keeping default settings there and bypassing the BOOTP protocol unless these settings cause the file transfer phase to fail. -

Freebsd Command Reference
FreeBSD command reference Command structure Each line you type at the Unix shell consists of a command optionally followed by some arguments , e.g. ls -l /etc/passwd | | | cmd arg1 arg2 Almost all commands are just programs in the filesystem, e.g. "ls" is actually /bin/ls. A few are built- in to the shell. All commands and filenames are case-sensitive. Unless told otherwise, the command will run in the "foreground" - that is, you won't be returned to the shell prompt until it has finished. You can press Ctrl + C to terminate it. Colour code command [args...] Command which shows information command [args...] Command which modifies your current session or system settings, but changes will be lost when you exit your shell or reboot command [args...] Command which permanently affects the state of your system Getting out of trouble ^C (Ctrl-C) Terminate the current command ^U (Ctrl-U) Clear to start of line reset Reset terminal settings. If in xterm, try Ctrl+Middle mouse button stty sane and select "Do Full Reset" exit Exit from the shell logout ESC :q! ENTER Quit from vi without saving Finding documentation man cmd Show manual page for command "cmd".

What are the source and destination addresses of this packet? 10.1.6.18 10.1.3.143 To what entities do these numbers refer? IP addresses Expand the Transmission Control Protocol triangle of the packet. What are the source and destination ports of this packet? i. 1720 ii. 32803 To what entities do these numbers refer? iii. Port numbers Note that wireshark is smart enough to "know" which ports are typically used by internet applications. what service is the host at IP 10.1.3.143 trying to access on the host with IP 10.1.6.18? [hint] Telephone call Read this discussion excerpted from here and answer the questions that follow as best you can. H.323 uses a single fixed TCP port (1720) to start a call using the H.225 protocol (defined by H.323 suite) for call control. Once that protocol is complete, it then uses a dynamic TCP port for the H.245 protocol (also defined by the H.323 suite) for capabilities exchange (caps exchange) and channel control. Finally, it opens up two dynamic UDP ports for each type of media that was negotiated for the call (audio, video, far-end camera control, etc.). This first port carries the RTP protocol data (defined by the H.225 specification) and the second one carries the RTCP data (defined by the H.225 specification). -

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address that is recognized in the local network. ARP stands for Address Resolution Protocol. When you try to ping an IP address on your local network, say 192.168.1.1, your system has to turn the IP address 192.168.1.1 into a MAC address. This involves using ARP to resolve the address, hence its name. Systems keep an ARP look-up table where they store information about what IP addresses are associated with what MAC addresses. 3 ARP CONT… . When trying to send a packet to an IP address, the system will first consult this table to see if it already knows the MAC address. If there is a value cached, ARP is not used. If the IP address is not found in the ARP table, the system will then send a broadcast packet to the network using the ARP protocol to ask "who has 192.168.1.1".
