I'm hoping that a Unix RPC programming expert can shed some light on using the rcmd() function call. The man page on this function states that you must have super user priviledges in order to envoke it as a client. Does the iruserok() function that controls client validation at the server allow rcmd to be used by clients other than the super user? If access to the rcmd() can be lowered so anobody other than the SU can use it, how would I use iruserok() to do this? Basically, I need to use the rcmd() function to execute a program on a remote server without requiring super user priviledges to do so. Can this be done?
