Hello. I'm sorry bothering you again. As I posted priorly here, NIS/YP does a lot of nasty things to me. The last weekend our whole server systems were down. The problem: OS: FreeBSD 4.2-STABLE as cvsupdated today the last time In my defined domain, I can not contact neither the local ypserver nor a remote ypserver. I set up the master server without being NIS client. /var/yp/securenets reflect localhost's address and the LAN's address and mask. I set up /var/yp/securenets on all NIS servers (master and slaves). portmap is running. ypserv is running on each machine. I used 'ypbind -s -S_DOMAINNAME_,local_yp_slave,remote_master,remote_slave' as described in the manpage to bind ypbind on a slave server to the local server. But that is not working! The ypbind daemon can not communicate with its server on the same machine. ypcat does not work. Login procedures take a lot of time.Against other opinions here it seems that NIS/YP is dependends on tcpwrapper, but I witched off tcpwrapper or set first line to ALL:ALL:allow. I switched off IPFW due suspecting the IP filter filtering UDP packets from portmapper. Nothing of that helped. On a considered slave server I can not run DHCP/TFTP with ypserv and ypbind, after this machine offerd IPs to its clients successfully, it drops by TFTP timeouts. This is not when NIS/YP is not running. I feel a little bit helpless this moment. Not the smallest, little configuration will work! Why is ypbind unable to contact a ypserv daemon on the same machine? I checked three times whether domainname is set up correctly, checked for the proper setup of /etc/passwd, group etc ... No chance to get it running. Another very suspicious behaviour revealed keyserv. I want to set up SecureRPC (but it was disabled when I tried to test how I could get YP running and working). On the master server, keyserv is running (keyserv -d -v). Additionaly, rpc.ypupdated is also running, ypserv (ypserv -n) runs, too. I tried to set up a hostkey for the local host, gave newkey -h master-server. name, enterd passowrd ... Then I wanted to create the /etc/.rootkey by keyserv -n, but after typing again the password I gave prior, I received an error. keyserv was unable to decrypt the given password ... Please help ... -- MfG O.
