embedded dropbear

[Ed Sutter]

Hi,
I managed to get dropbear-ssh running under a uC/OS-II thread.
Obviously had to do a lot of hacking to make this work, and
I'm sure its not the most efficient way of doing it.

Not being an ssh/cryptography wizard by any stretch of the
imagination, I have two questions that may be trivial...

1..
Because I'm not on a Unix-ish system, I don't have any of
the /proc stuff or /dev/urandom for seedrandom().  Is it
essential that this function have *that* much random
input?  How does this affect the security of the connection?

2..
I essentially hard-coded the -r option (ssh server) to use a
pre-established rsa_host_key file.  Should this file be built
once for a given system, and then reused or is this something
that should be recreated each time the server is started?

Thanks in advance,
Ed
