Hi Greg,

  I'm using a debian linux as OS with a 2.4 kernel running on it.

  I'm reconnecting each time I want to retrieve a message. The idea is I 
have a lilbrary of messages and I want to pick one of it randomly. I don't 
know if there is the possibility to seed the random number generator 
manually, anybody knows it?


Thanks to all
