If the NIS slave server problem is not obvious, you can work around it while you debug using rcp or ftp to copy a recent version of the inconsistent map from any healthy NIS server. The following shows how to transfer the problem map.
ypslave# rcp ypmaster:/var/yp/mydomain/map.\* /var/yp/mydomain |
The * character has been escaped in the command line, so that it will be expanded on ypmaster, instead of locally on ypslave.
