PORT 20

PORT 20 TCP/UDP




File Transfer Protocal (FTP) [data transfer]




A standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet.

PORT 21

PORT 21 TCP/UDP




File Transfer Protocol (FTP)[Control]



PORT 22

PORT 22 TCP/UDP




Secure Shell Host (SSH), secure log in, file transfers (scp, sftp) and port forwarding. A network protocol to allow remote login and other network services to operate securely over an unsecured network.

PORT 23

PORT 23 TCP/UDP




Telnet protocol—unencrypted text communications (DATA)


Telnet provided access to a command-line interface (usually, of an operating system) on a remote host. Most network equipment and operating systems with a configuration (including systems based on Windows NT)

PORT 25

PORT 25 TCP/UDP




Simple Mail Transfer Protocol (SMTP), used for e-mail routing between mail servers


Send and receive mail messages, user-level client mail applications typically use SMTP only for sending messages to a mail server for relaying. For receiving messages, client applications usually use either POP3 or IMAP.

PORT 37

PORT 37 TCP/UDP




Time Protocol

PORT 43

PORT 43 TCP


WHOIS


is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format

PORT 53

PORT 53 TCP/UDP




Domain Name System (DNS)




Distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain.

PORT 67

PORT 67 TCP/UDP




Bootstrap Protocol (BOOTP) server; also used by Dynamic Host Configuration Protocol (DHCP)

PORT 68

PORT 68 TCP/UDP




Bootstrap Protocol (BOOTP) client; also used by Dynamic Host Configuration Protocol (DHCP)

PORT 80

PORT 80 TCP/SCTP




Hyper Text Transfer Protocol (HTTP)




An application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.

PORT 101

PORT 101 TCP/UDP




NIC host name

PORT 107

PORT 107 TCP/UDP




Remote Telnet Service Protocol (RTSP)

PORT 109

PORT 109 TCP/UDP




Post Office Protocol v2 (POP2)


An application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection. POP has been developed through several versions, with version 3 (POP3) being the last standard in common use before largely made obsolete by the more advanced IMAP.

PORT 110

PORT 110 TCP/UDP




Post Office Protocol v3 (POP3)




An application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection.

PORT 115

PORT 115 TCP Only




Simple File Transfer Protocol (SFTP)

PORT 118

PORT 118 TCP/UDP




Structured Query Language (SQL) Services

PORT 123

PORT 123 TCP/UDP




Network Time Protocol (NTP), used for time synchronization

PORT 137

PORT 137 (TCP/UDP)




NetBIOS Name Service (NNS)




Name service (NetBIOS-NS) for name registration and resolution.

PORT 138

PORT 138 TCP/UDP




NetBIOS Datagram Service (NDS)




Distribution service (NetBIOS-DGM) for connectionless communication.



PORT 139

PORT 139 TCP/UDP




NetBIOS Session Service (NSS)




Session Service (NetBIOS-SSN) for connection-oriented communication.

PORT 143

Internet Message Access Protocol (IMAP)




An Internet standard protocol used by e-mail clients to retrieve e-mail messages from a mail server over a TCP/IP connection. IMAP is defined by RFC 3501

PORT 153



PORT 153 UDP


Simple Gateway Monitoring Protocol (SGMP)


Allows commands to be issued to application protocol entities to set or retrieve values (integer or octet string types) for use in monitoring the gateways on which the application protocol entities reside. Messages are exchanged using UDP and utilize unreliable transport methods. Authentication takes place on UDP port 153. Interface Status, Route Type, Route protocol

PORT 161

PORT 161 UDP Only




Simple Network Management Protocol (SNMP)


An Internet-standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more.

PORT 162

PORT 162 TCP/UDP


Simple Network Management Protocol Trap


(SNMPTRAP)

PORT 194

PORT 194


Internet Relay Chat (IRC)




An application layer protocol that facilitates communication in the form of text. The chat process works on a client/server networking model. IRC clients are computer programs that a user can install on their system. These clients communicate with chat servers to transfer messages to other clients

PORT 443

PORT 443


Hyper Text Transfer Protocol Secure (HTTPS)




HTTPS signals the browser to use an added encryption layer of SSL/TLS to protect the traffic.

PORT 264

PORT 264 TCP/UDP


Border Gateway Multicast Protocol (BGMP)




An IETF project which attempted to design a true inter-domain multicast routing protocol. BGMP was planned to be able to scale in order to operate in the global Internet.

PORT 520

PORT 520 UDP


Routing Information Protocol (RIP)




RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination. The maximum number of hops allowed for RIP is 15

PORT 860

PORT 860 TCP (iSCSI)


SCSI commands over IP networks, iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances. iSCSI can be used to transmit data over LANs, WANs, or the Internet and can enable location-independent data storage and retrieval. It is a storage area network (SAN) protocol, allowing data center storage arrays while providing hosts (such as database and servers) with the illusion of locally attached disks.

PORT 1512

PORT 1512 TCP/UDP


Windows Internet Name Service (WINS)


Effectively, WINS is to NetBIOS names what DNS is to domain names a central mapping of host names to network addresses. Like the DNS, it is implemented in two parts, a server service (that manages the embedded Jet Database, server to server replication, service requests, and conflicts) and a TCP/IP client component which manages the client's registration and renewal of names, and takes care of queries.

PORT 2049

PORT 2049 TCP/UDP
