I have collected some more information on our problem to post it again: Problem: NIS-login, RPC On prt-i3 we installed Debian 0.93
While booting, there is the following error message (3 times), and there seems to be coherence with NFS mounts in /etc/fstab, because if I comment them out, there are no errors. Manual mount works in any case without errors. But now the error message: clnttcp_create: RPC: Port mapper failure - RPC: Unable to receive After booting, NIS-logins work fine, but after an indefinite time, NIS-logins no longer work: $ telnet prt-i3 Trying 132.176.1.66 ...
