You can also run 'makedbm -u dbm-filename' to extract all the key/data pairs.
Using ypcat, as mentioned previously, is cleaner but this method has the advantage of working even if the server(s) are down. Note that you do get "key (space) data" pairs AND the two special key entries YP_LAST_MODIFIED and YP_MASTER_NAME this way too. You can also run this to recover data from a DBM map on the master server after a crash, when you find your source file got trashed, and you know you have a bunch of updates in there past even the most recent backup that is only a few hours old (now how would I know that...).

Hey all y'all. I know how to configure a nis master and a nis slave, so if the master goes down, the slave will take over the traffic. But I'm afraid of what happens if the master catches fire. Because the slave only answers queries, it doesn't keep a copy of its own files, I have no way to pick up the pieces and move on, if the master suffers a catastrophic failure. For example, suppose the master loses its hard drive completely. And the slave starts taking all the traffic. And then I decide to add a new user. Well, I no longer have the /etc/passwd file that the master was serving, and all those other files. So how, then, could I run make from /var/yp? It seems to me that I'd be up the creek. Anybody have any good suggestions to help me with my reliability fears? Thanks in advance....
