ypxfr

ypxfr is a command-line utility that can be used to transfer NIS (Network Information Service) maps between machines. NIS is a service that provides a central repository for user and group information.

The ypxfr command is used as follows:

ypxfr [options] [source machine] [destination machine]

  • options: These are optional flags that can be used to control the behavior of the ypxfr command.

  • source machine: This is the machine that the NIS maps are being transferred from.

  • destination machine: This is the machine that the NIS maps are being transferred to.

The ypxfr command has a number of options that can be used to control the transfer process. Some of the most commonly used ypxfr options are:

  • -s: This option specifies the source machine.

  • -d: This option specifies the destination machine.

  • -t: This option specifies the timeout for the transfer in seconds. The default timeout is 30 seconds.

  • -v: This option prints verbose output to the console.

For example, the following command will transfer the NIS maps from the machine source to the machine destination:

ypxfr -s source -d destination
