Not that this really suprised me, but it effectively makes any rsh command useless that tries to take data from stdin. The bug is that Winlose never sends a FIN flag, but immediately sends a package with an RST in it. This causes the remote command to be aborted (as opposed to see a closed connection, and process it as an EOF condition). Since your problems always happen while the sendmail is waiting for the QUIT handshake, it may be the same problem. Dunno if this is only apparent for some version of Winlose 95. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
