- Doncha just love NIS? *sigh*. There is a patch which
- "fixes" it, but at a significant performance penalty. Here's part
- of the README for patch 100342-02:
-
- -----
- Bug 1046416:
-
- If you bring a ypserver down into single user and then boot it into
- multi user by either typing control D or reboot, the yp clients
- will take a long time to rebind to the server.
-
- ********************* WARNING ******************************
-
- This is a new version of ypbind that never uses the NIS
- binding file to cache the servers binding. This will have
- the effect of fixing the current symptom. However, it might
- degrade the overall performance of the system when the
- server is unavailable. This is most likely to happen on an
- overloaded server, which will cause the network to produce
- a broadcast storm.
-
- *************************************************************
-
- -----
-
- Personally, I haven't applied this patch, but I'm tempted
- to. I'm sick and tired of NIS just going out the window whenever
- an NIS client reboots. Somehow I think Sun could have thought up
- a smarter fix to the problem than this.
