Lotus Domino Administrator 8 Help - Modifying Web server Internet port and protocol settings

WEB SERVERS

Modifying Web server Internet port and protocol settings
In certain cases, you may need to change some default Internet port and protocol settings. Check carefully before changing the defaults.

To modify Web server Internet port and protocol settings

1. Open the Server document that you want to edit.

2. (Optional) Click Ports - Internet Ports - Web. Under Web (HTTP/HTTPS), complete these fields:

Field Action

TCP/IP port number Enter a port number. Default is 80.

TCP/IP port status Choose one:

Enabled -- To configure the server to listen for HTTP requests on the specified TCP/IP port.
Disabled -- To prevent the server from listening for HTTP requests on the specified TCP/IP port.
Redirect to SSL -- To redirect any HTTP requests that come into the TCP/IP port to the SSL port.

Enforce server access settings Choose one:

Yes -- To enforce server access settings for this protocol on the server. Server access settings are found on the Security tab of the Server document, and specify the names of authenticated users who have been granted access to this server, and those who have not.
No -- To not enforce server access settings for this protocol.

SSL port number Enter a port number. Default is 443.

SSL port status Choose one:

Enabled -- To configure the server to listen for HTTPS requests on the specified SSL port.
Disabled -- If you do not want to use SSL for this server.

3. (Optional) Click Internet Protocols - HTTP, and in the Basics section, complete these fields:

Field Action

Bind to host name Choose one:

Enabled -- To enter up to 32 IP addresses and/or DNS names in the Host name(s) field to which the Domino server will bind. This allows users to access a Web server using a name other than the Domino server name.
Disabled (default) -- To bind to all IP addresses on the server.

DNS lookup Choose one:

Enabled -- To have IBM® Lotus® Domino™ look up the DNS name of the requesting client. The Domino log files and database contain host names corresponding to the machine used by the Web client.
Disabled (default) -- To not look up the DNS name of the requesting client. The Domino log files and database contain IP addresses.
Choosing Disabled improves the performance of the Domino server because the server does not use resources to perform the DNS name lookup.
Note The majority of browser users connect to the Internet through Internet server providers (ISPs), so the host names returned by DNS lookup are those of the ISP's proxy servers, not the individual user machines.

DNS lookup cache Choose one:

Enabled -- To have Domino cache the results of a DNS lookup for faster retrieval.
Disabled -- To not have Domino cache DNS lookup results.

DNS lookup cache size Specify the maximum size of the DNS lookup cache. Default value is 256.

DNS lookup cache found timeout Specify the length of time, in seconds, that IP addresses remain in the cache. Default value is 120 seconds.

DNS lookup cache not found timeout Specify the length of time, in seconds, between failed DNS lookups for a particular item. Default value is 240 seconds.

4. (Optional) Click Internet Protocols - HTTP, and in the Network Settings section, complete these fields:

Field Action

Listen Queue Size Specify the size of the operating system listen queue for incoming HTTP connections. Default is 512.

Maximum number of concurrent network sessions Specify the maximum number of network connections the HTTP server will handle before refusing incoming connections. Default is 2000.

5. Save and close the document.

6. Enter this command at the console so that the changes take effect:

tell http restart
