[uml-user] 2 UML clients, fighting for network (uml-bridge)

2005-03-02 Thread Matt Simonsen
I am using a bridge for 2 uml clients. It works beautifully with only one client, then after I startup the second the network randomly cuts out for each system. I've noticed I can "kill" one by pinging the other one. For example if UML#1 network dies and I ping it, suddenly UML#2 is unpingable

[uml-user] A hardware random number generator for UML

2005-03-02 Thread Jeff Dike
I wrote a little HW random number generator based on hw_random.c. It hooks itself up to major 10, minor 183, which seems to be the standard for a HW RNG. The standard name for this seems to be /dev/hwrng. I don't know if the ususal random number consumers look for /dev/hwrng before /dev/random,
