I seem to have read about this somewhere, probably in another > mailing list. Ah.... I made a mistake. In some unices, /dev/random is not available. But in your case, it seems that /dev/random (or an entropy source) is already present. My guess is, when a connection is requested, random bytes from the entropy pool are requested to generate a session key. When the pool is exhausted, it will need to recharge, thus, the long pause. At least, that's how it works with Linux. I hope the analogy is still valid with Solaris. :-\ -- Under capitalism, man exploits man. Under communism, it's just the opposite. -- J.K. Galbraith
