Dear Sirs. Again, I would like to ask for some hints about NIS/YP. I already set up our domain and it contains a master and several slaves. Setting up master NIS server was easy, but slaves seems to be a great deal. Two of three servers should be slaves, and they also should be NIS clients. I also set up SecureRPC as described in the manpages, have inetd running with tcpwrapper facility for both internal and external services (inetd -lwW) and running IPFW. But the below described symptomes are still present when disabling tcpwrapping, ipfw and SecureRPC (means: switching off all related daemons, deleting all related files like /etc/publickey and /etc/.rootkey, ipfilter is transparent for all traffic coming from all over the net). On machines running ypserv (either ypserv -n or ypserv) and acting as slave servers I can not bind ypbind to this system nor running ypbind anyway. I tried to use ypbind -s -S Domain,Host1,host2 as host1 and host2 are names located in /etc/hosts (I use the same base file on master and slaves to avoid mistakes for especially this testing purpose) and ypbind -s or simply ypbind - but it is everytime the same: NIS does not work! On a client machine I can rund ypbind, but it never attaches to its master. ypbind is not able to communicate with the on the same host running ypserv daemon (why??). I tried prior to install a NIS/YP environment completely free of secure stuff (no IPFW, no warpper, no SecureRPC), but every time I ran make in /var/yp I got an error message: can not create UDP handle to slave server, host unknown or similar. Another very curious phenomenon is when trying to connect via ssh or telnet to a host running ypbind: telnet timed out after typing the loginname after a while when coming up and ssh crashes (seen on the console of the apropriate host, SIG 11) and dumps a core. On another machine, acting as DHCP server and boot server for our diskless X-terminals, tftp does not work, the x-client always reports a tftp timeout after it got its IP from the dhcp server. The communication with each of the faulty hosts is clear without NIS/YP, but it gets harsh when running ypbind ... -- MfG O.
