Nope. 64 MB per host. I have not had more than 10 per machine so far, so thats 640MB used out of 1 GB. I am using tmpfs too... Yes, swap is huge (300 MB). But it never gets used unless you do a yum upgrade (which needs 200 MB!). Noone has tried this yet, but I can monitor that by creating the swap with sparse blocks and using du. > > I've had good results with openvpn, but wouldn't have thought of it for > connecting from a student's workstation to a UML guest. Openvpn connects each server together to form a virtual host, so that I can NAT all the UMLs at one location for logging and security purposes. Only telnet or ssh runs on each student machine, everything else is remote. I just noticed that one of my problems is that openvpn goes down every so often (like under heavy load). No logs produced, but the tun in the routing table is deleted. I forgot to put this route back in again (fixed now) in the up script. Should have used persistent tuns! Goodness knows why is goes down, but it comes up again immediately (less than 5 seconds downtime). Just my scheduling worries to fix now.
