I just released 2.6.2 with numerous fixes for makedns. You might want to upgrade to it and also take note of the release notes for 2.6.1 and 2.6.2. There are some requirements on setup for makedns to work with the new ddns.pm. At least at that point you will be working with the lastest makedns fixes that Sun Jing has provided.

Unfortunately I'm not seeing any db.*.jnl files being created, nor are the zone files being populated when I restart named. When I run makedns it does seem to be doing *something* since it takes about 4 seconds for it to complete, but nothing shows up in any of the files in /var/named and no queries to the DNS server with the names/IP's of defined nodes returns anything: # time makedns -n Getting reverse zones, this may take several minutes in scaling cluster.

After makedns -n, you can see zonefiles(db.*) are created in /var/named, while it's correct that you can only see something like this in it: ------------------------------------------- [root@ca4lpar01 named]# cat db.192.168.11 $TTL 86400 @ IN SOA ca4lpar01.local. root.ca4lpar01.local. ( 2011080200 10800 3600 604800 86400 ) IN NS ca4lpar01.local. ------------------------------------------- Because the DNS records are actually in db.*.jnl, it's binary file, if you run "service named restart", then named will dump the DNS records from db.*.jnl to db.<zone>, for example: ------------------------------------------- [root@ca4lpar01 named]# cat db.192.168.11 $ORIGIN . $TTL 86400 ; 1 day 11.168.192.IN-ADDR.ARPA IN SOA ca4lpar01.local. root.ca4lpar01.local. ( 2011080201 ; serial 10800 ; refresh (3 hours) 3600 ; retry (1 hour) 604800 ; expire (1 week) 86400 ; minimum (1 day) ) NS ca4lpar01.local. $ORIGIN 11.168.192.IN-ADDR.ARPA. 10 PTR c1n01.local. 107 PTR ca4lpar01.local. [root@ca4lpar01 named]# ------------------------------------------- So I think the point here is if you have db.*.jnl created in /var/named? does nslookup work for you? Thx. Jing Bruce Pennypacker <[email protected]> To 2011-08-02 03:07 [email protected] ge.net cc Please respond to xCAT Users Mailing list Subject <[email protected]> [xcat-user] makedns results in empty zonefiles I'm using xCAT 2.6.1. I've defined my site & networks, and generated a hosts file using makehosts -n which looks correct. But now when I try to generate a DNS config using makedns -n I just end up with a bunch of zonefiles in /var/named that are empty save for the header: $TTL 86400 @ IN SOA jacket.uit.tufts.edu. root.jacket.uit.tufts.edu. ( 2011080100 10800 3600 604800 86400 ) IN NS jacket.uit.tufts.edu. Why would hosts be written to /etc/hosts when you run makehosts -n but nothing gets added to DNS when you run makedns -n?
