aes cipher when receiving packets, no compression in either direction,
and Group1 key exchange.
<?php /* Notify the user if the server terminates the connection */ function my_ssh_disconnect($reason, $message, $language) { printf("Server disconnected with reason code [%d] and message: %s\n", $reason, $message); }
