Ok, just to see if I got the things clear... :)
1) the daemon will listen for incoming TCP connections using a
non-blocking socket (just as the openMosixInfoServer does right now);
2) if the daemon needs to grab some exotic info like /proc/uptime from a
remote node, it would UDP to the specific machine, waiting for a reply
(we probably need to set up a timeout for things like this);
3) if the daemon needs to grab some exotic info which requires more than
a bunch of raw data, then it should be using TCP to connect directly to
the remote node, probably using the standard daemon TCP interface
mentioned in point 1.
I don't think we're going to need the latest (3) since all we want to
know is already available locally from /proc, /proc/hpc and
/proc/hpc/nodes. The "exotic" things are not likely to require more than
a simple, short UDP packet (request + reply).
These are my own thoughts. Feel free to bash me for any incorrect
statement please ;)
