When pxeboot gets a 0 as a port number from portmapper (indicating an error), it currently happily sends NFS packets to the server's port 0 in an endless loop. Change this to instead bail out with a useful message. This happens, for example, with recent Linux NFS servers as many distributions switched to TCP only NFS serving by default. FreeBSD's pxeboot must have UDP. In this situation pxeboot asks the server's portmapper for the UDP NFS port and since there is none gets 0. Also add a hint to the manpage explaining this and how to fix it. Reviewed by: ziaee, kevans, imp
FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
