What output did you expect, and what output did you actually get? Have you tried different options to 'comm'? If the list contains only numeric IP addresses, the '-i' option isn't going to do you much good, for example. Have you tried 'diff file1 file2'? Do you get the output that seems reasonable from that? -Chris P.S. please keep freebsd-questions@freebsd.org CC'ed, and please don't top-post.
