I have a user who wants to use the rstat system call to get statistics
across the network from an alpha, to be displayed on some other unix box.
He's modeled his code on "perfmon", using calls to rstat to startup rstatds
on the nodes to be watched. We were able to get rstatd sort of running by
uncommenting its entry in /etc/inetd.conf and restarting inetd, but when
I try to access the node from another node, using the code, I get:
Nodename: Permission denied
Any ideas as to what to tweak to allow startup of rstatd by a user, remotely?
I'll append the gist of the code at the bottom (with much deleted for
brevity - just saved references to rstat, mostly)
Many thanks in advance...
