Once you have selected an exploit, the next step is to determine what options it requires. This can be accomplished with the show options command. Most exploits use RHOST to specify the target address and RPORT to set the target port. Use the set command to configure the appropriate values for all required options. If you have any questions about what a given option does, refer to the module source code. Advanced options are available with some exploit modules, these can be viewed with the show advanced command.
