It's a setup failure for rcmd(3) in libc. Basically what happens is that the outbound connection (from rsh to rshd) causes a reverse direction connection from rshd back to rsh for the control and stderr backchannel. All these are supposed to be checked for privileged ports, etc etc. I don't remember all that well, but it's something like that. ipfw is a likely suspect if it's filtering incoming connections to reserved ports etc. > John > -- > John Hay -- John.Hay@mikom.csir.co.za Cheers, -Peter -- Peter Wemm Netplex Consulting To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
