Q: Why doesn't my new slave server get NIS maps when they are made?
A: You have not added the new slave to your ypservers map. You can verify this by examining the ypservers map: # ypcat -k ypservers Section 3.3 explains how to update the ypservers map. You may also have problems if your slave server doesn't already have copies of the maps. See the first questions in section 4.3 for how to remedy this situation.
Q: Why does my groups map not get correctly distributed?
A: Because the netid was not distributed, the groups map does not have all the correct info. Run the following on the master to ensure that the netid is also distributed: # cd /var/yp # rm netid.time # make netid For groups updates to occur, both groups and netid must be distributed. It is always best to just run 'make' and let the processes make and distribute whatever maps have changed. Running make source-file may not update all maps that require changes.
Q: Why is my change to the NIS maps not showing up?
A1: You did not do a make on the NIS master. You can verify this by examining the map with ypcat. To resolve the problem, go to the NIS master and make the files: # cd /var/yp # make A2: If make has been run, you are probably bound to a NIS slave which is not getting updates. You may wish to retry the make, in case the NIS slave was down the first time it was run. Otherwise, you probably need to update the ypservers map. Run ypwhich to see which slave you are bound to, and then examine the ypservers map to verify the problem: # ypwhich slave-3 # ypcat -k ypservers master slave-1 slave-2 If you find that the name which appears in 'ypwhich' does not appear when you look at the ypservers map, follow the instruction in Section 3.3 to update your ypservers map.
