 Hi Rudolf,
 
 I tried reproducing the EISCONN error with the program at:
 
 	http://people.freebsd.org/~keramida/files/conn.c
 
 A connection is made to localhost:22 (sshd must be running for this to
 succeed), and then sendto() is used to send a packet to a different
 host over the same socket.
 
 EISCONN was never returned in 6.0-CURRENT.  The packet is AFAICT
 silently dropped.
 
 Am I doing something wrong?
