With older versions of OpenSSH, I frequently see the client complain of a "truncated packet" (SSH has its own internal packetized protocol) and drop the session. Sometimes this is just a minor inconvenience -- for example, if I'm doing POP over the forwarded port I sometimes find that the mail client becomes confused and/or does not filter incoming messages properly. It's a bigger concern if I'm doing administration and am cut off in midstream. --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
