Unless I am not mistaken one of the differences between 4.3 and 4.5 is that inetd does, by default, not listen on ftp or telnet any longer. Look in /etc/inetd.conf and check what ports it is listening for. For me, running 'lsof -i| grep inetd' on 4.5 gave the following inetd 90 root 4u IPv4 0xc3736a40 0t0 TCP *:ftp (LISTEN) inetd 90 root 5u IPv4 0xc3736820 0t0 TCP *:smtp (LISTEN) which is exactly what I would expect, since those are the only two ports I have told inetd to listen on. -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
