Re: nscd again (nis client cache)
I wanted to say Thanks!!! for this example, because before this point I was under the impression that nscd/cached was of no use for NIS clients, only LDAP or maybe other directory systems that I don't use. I tried "cache compat" as below for passwd and group and it works! Our NIS entries at work are big enough that without the cache, top takes 7+ seconds to open, ssh login takes a few seconds, and samba logins were concerningly slow. I did not try samba connections, but the other methods are much faster now on the second run. Wanted to post this for the archive too.

I mean lines like "group_compat: cache nis" aren't supported. 2. Cache should work ok with the configuration you've mentioned in your first example, i.e.: "group: cache compat". Just checking - why do you think that cache isn't working? The correct way to determine it is to perform the same query twice. During the first pass (when query is not cached), the request will be processed by NIS module and you'll have all the NIS-related stuff in the logs. On the second pass the request should be handled by scd module - and you shouldn't see any activity in NIS logs. It would be great to see the debug log (with nscd log turned on) separately - for the first and the second pass. It would help to find the error in nscd, if there is one.
