ssh Connection refused due to "Entropy collection failed and entropy exhausted"

After system hang, I restarted the server and cannot ssh to another machines anymore.
Please kindly help. Thanks~

Yes, but prngd can well serve as a surrogate entropy source.

It seems that everything is correctly installed and that prngd is running.
The only thing I can see is that "prngd" has used up quite a lot of CPU in a short time
which is not normal.

I think you should stop and restart the prngd process, wait a bit and retry,

Maybe you should even delete (rm) the socket "/var/spool/prngd/pool" after stopping and before restarting prngd.

Could you please post the permission setting of the /etc/entropy folder.

Solaris 8 does not have a source of entropy standard. You need to install patch 112438 (any version) before you build ssh.
