Linux: Setting TCP/IP options

Select from a range of TCP/IP options for the IBM Spectrum Protect™ server or retain the default.

About this task

The following is an example of a list of TCP/IP options that you can use to set up your system.
commmethod        tcpip
  tcpport         1500
  tcpwindowsize   0
  tcpnodelay      yes
Tip: You can use TCP/IP Version 4, Version 6, or both.
TCPPORT
The server port address for TCP/IP and SSL communication. The default value is 1500.
Linux operating systemsTCPWINDOWSIZE
Linux operating systemsSpecifies the size of the TCP/IP buffer that is used when sending or receiving data. The window size that is used in a session is the smaller of the server and client window sizes. Larger window sizes use additional memory but can improve performance.

You can specify an integer from 0 to 2048. To use the default window size for the operating system, specify 0.

TCPNODELAY
Specifies whether or not the server sends small messages or lets TCP/IP buffer the messages. Sending small messages can improve throughput but increases the number of packets sent over the network. Specify YES to send small messages or NO to let TCP/IP buffer them. The default is YES.
TCPADMINPORT
Specifies the port number on which the server TCP/IP communication driver is to wait for TCP/IP or SSL-enabled communication requests other than client sessions. The default is the value of TCPPORT.
SSLTCPPORT
(SSL-only) Specifies the Secure Sockets Layer (SSL) port number on which the server TCP/IP communication driver waits for requests for SSL-enabled sessions for the command-line backup-archive client and the command-line administrative client.
SSLTCPADMINPORT
(SSL-only) Specifies the port address on which the server TCP/IP communication driver waits for requests for SSL-enabled sessions for the command-line administrative client.
