Hi, We can't change nis password on your server using yppaswd : after "Retype New Password:" server says "yppasswd: pam_chauthtok(): error in service module". In /var/log/messages : <kern.info> nisserver kernel: pid 5196 (rpc.yppasswdd), uid 0: exited on signal 11 <user.err> nisserver yppasswd: in pam_sm_chauthtok(): yppasswd_local(): NIS password update failed: monstrogoth.esil.univ-mrs.fr: RPC: Unable to receive; errno = Connection reset by peer In /var/yp/ : a new file named pw.XXXXXX containing the first lines of master.passwd.vim ( 67 of 827 ) If we restart rpc.yppasswdd and try again, the same error occurs, and a new file pw.XXXXXX of the same length is created. Any help appreciated.
