Dear Sirs. Maybe this is a kind of "newbie" question, but it seems really serious to me in a way I can not figure out how and why. I need to set up a secure NIS/YP environment for our small institute. For this reason, I have two servers already set up, one of them should play the role of the master server, the other one has to play the role of the slave and in the near future I will set up a third slave machine to provide a general YP service for all our FreeBSD clients. I consulted the handbook for introductions and I read some additional stuff and all sounds not that hard as it is supposed to be shown to me. On the master server all things run all right. ypserv is started, additionaly, I use the rpc.ypxfrd daemone to speed up map distribution. These are the daemons on the master server side: 167 ?? Is 0:00.04 ypserv -n 169 ?? I 0:00.04 rpc.ypxfrd 171 ?? Is 0:00.00 rpc.yppasswdd -f -s -i 175 ?? Is 0:00.01 rpc.ypupdated /var/yp/securenets is set up correctly. /var/yp/ypservers contains the names of all servers. When starting a refresh, the make-script tells me all things are going all right except the fact that it can not build up an UDP handle to the slave server, because this server is unknown. Well, this server is not unknown, it's my slave machine running rpc.ypxfrd on it in addition to ypserv and a correctly set up domainname. /var/yp/securenets is set up correctly and again, on the slave side /var/yp/ypservers contains the names of all servers, too. Maybe this is uneccessary, but so I think I avoid fogetting something. Because I use inetd with mode "-wW" I set up /etc/hosts.allow n that way, that communication within my local network is allowed and passed through. The same thing is assigned to the IP filtering facility: local tcp and udp are passed unfiltered through the LAN of our institute. But it stills seems that the master server is unable to build a UDP connection to the slave, it tries it, but it fails due "host not known". I use two other slave names in /var/yp/ypservers which are not alraedy connected to the network and the failure of connecting to these unknown machines seems to be different from the failure I receive which is produced when accessing the present slave, so I suspect an UDP connection problem, caused by some security facilities. But I have no glue what the reason could be. Hope there is someone with the "great glue" ... thanks in advance, oliver - MfG O.
