If you are using rsh with the ch_p4 device, you may need to set up your machine to allow the use of rsh. You should do this only if you are a system administrator and understand what you are doing or you are using an isolated network. For example, if you are using Linux on a collection of computers at your home or at work, and these machines are not connected to a larger network, you should follow these directrions. If any of the machines are connected to another network, talk to the administrator of the network about the policy for using rsh. Alternately, consider using ssh (Section Configuring with ssh ) or the secure server (Section Faster job startup for the ch_p4 device ).
The following explains how to setup a single machine so that it can use
rsh to itself to start processes.
To setup rsh, you need to ensure that you have a file
/etc/hosts.equiv that contains at least
localhost your_machine_namewhere your_machine_name is the name that you've given your machine in /etc/hosts.
You may also need to ensure that the files /etc/hosts.allow and /etc/hosts.deny are empty.
When using a machine that is not networked, for example, a laptop while travelling, you may need to change your network settings. Under some versions of Linux, use the netcfg and set Hostname to localhost and Domain to localdomain.
