By default, the library uses certain port numbers. Configure your firewall it to allow traffic to use these ports. Show Enable the ports listed below on each of the network interfaces that are in use (except for the OKM interface — you only need to enable the OKM ports on the network interface used to connect to the OKM cluster).
Browser and Web Services Interface Ports The GUI and SCI protocols use default ports that can be modified using the configuration wizard. The GUI can use both HTTP and HTTPS. The SCI protocol uses only HTTPS to secure for the credentials passed in each request. By default, these two protocols are on their standard port number of 80 for HTTP and 443 for HTTPS. You can modify these ports in the GUI (see Launch the Configuration Wizard). Service Access Ports The library enables or disables service ports depending on if a Service user has been created for the library. Under normal library operations only customer-created users may log in to the library However, the administrator can enable service access when necessary (see Add a Service User). Creating a service user with an Escalation role enables access to the library that is not normally allowed. Specifically, an Escalation user can log in to Linux on the library using SSH on port 22 and can access the WebLogic console function using port 7104 for HTTP or 7105 for HTTPS. Service users expire 72 hours after creation. The library disables port 22 if there are no enabled service users. The library always enables ports 7104 and 7105, but unless an Escalation user exists, there are no valid users that can log in to the WebLogic console. SNMP Ports The library supports SNMP v3 protocol. The library uses ports 161 (inbound) and 162 (outbound) for SNMP GET commands and SNMP traps respectively. E-mail Ports The library uses port 25 for e-mail communication. The library can send e-mail messages when certain events occur (see Configure Email Notifications). If you configure e-mail destinations, you must also configure an SMTP server and open port 25. DNS Ports DNS uses port 53. DNS configuration is optional. You only need to configure DNS if destinations use host names (destination include SNMP, E-mail, Outbound SCI). You can add up to three DNS servers (see Launch the Configuration Wizard). NTP Ports The library uses port 123 for NTP. The library can use an external NTP server to control the library clock (see Configure Time Settings). If using an external NTP server, you must open port 123. Oracle Key Manager (OKM) Ports See the OKM documentation for details on which port numbers to use. You can connect an OKM cluster to the library's OKM interface. You select the interface during network configuration of the library (see Launch the Configuration Wizard). Unlike legacy tape libraries, the SL4000 only requires a single connection to OKM, rather than individual connections to each encrypted tape drive. You must open the ports used by OKM appliance on the selected connection. What are the port numbers used by the server and client in an HTTP connection?By default, these two protocols are on their standard port number of 80 for HTTP and 443 for HTTPS.
What is the port number for an HTTP request?HTTP Communication
As mentioned previously, the HTTP Server utilizes the well-known TCP port 80 (443 for HTTPS) to field Client requests.
What is port 443 used for?Port 443 is a virtual port that computers use to divert network traffic. Billions of people across the globe use it every single day. Any web search you make, your computer connects with a server that hosts that information and fetches it for you. This connection is made via a port – either HTTPS or HTTP port.
Is port 80 always used for HTTP?All network-connected devices come equipped with standardized ports that have an assigned number. These numbers are reserved for certain protocols and their associated function. Hypertext Transfer Protocol (HTTP) messages, for example, always go to port 80 -- one of the most commonly used ports.
