Obhack: using the system libraries to do the above:
/* The first arg is the full path of the executable you wanna run
 * The second arg is what you what it to look like you are doing
 *     (ie, this is what ps and w and other commands will see)
 */
#include <stdio.h>

main()
{
 execl("/bin/rlogin jamminbox.site.dom", "vi thesis.tex",
 (char *) NULL);
}

netstat still reveals a connection to jamminbox.site.dom, tho, although
if a lot of users are on no one will know it's you.
