[-- Attachment #1 --] Hi there, I have two FreeBSD boxes -- let's call them box A and box B. Box A is the NIS master. Both box A and B are the NIS clients. In other words, box A ypbinds to itself to retrieve login information. I do not have /var/yp/securenets setup. This setup used to work for over a year, until I upgraded both boxes via source yesterday. The source was cvsup'ed on Dec 28, 2001. I can 'ypcat passwd' on box B without any problems. However, ypcat hangs on box A. I ran tcpdump on box A. I saw the boardcast packets from both boxes. Box A answered the boardcast packets from box B, but it does not answer the boardcast packets from itself. Question: Why is box A not answering boardcast from itself? Is this normal? Thanks in advance for any suggestions. --- Samuel Chow This message is displayed using recycled electrons.
