[xcat-user] Service Node trying to update Master DNS
Hello all, I have one xCAT MN and two SNs along with an external DNS server that they all interact with. The SNs act as slave DNS servers that only sync down changes made to the external (master) DNS server that is updated by commands like 'makedns -e' from the MN only. An issue I am running into, that I haven't tried since I moved to the MN/SN hierarchy model, is that during a PXE deploy the new node gets a DHCP IP from one of the SNs and then that SN tries to add the node's IP to the external DNS server and can't. The SNs are not authorized to update the DNS entries since it is a readonly slave that just syncs what it sees on the master external DNS server. I can manually alter their named.conf to allow updates to be pushed up from the slave named servers on the SNs, but I wanted to check and see what others are doing for this issue first and whether you allow your SNs DNS slaves update the master DNS. Perhaps I configured something incorrectly to begin with. One thing I do need to figure out though is why the node's entry in /var/lib/dhcpd/dhcpd.leases is saying dynamic though instead of fixed-address and doesn't list the IP that shows for the node's config with an lsdef. Perhaps that is why the makedns -e doesn't seem to help, because it picks a different IP then tries to add it. Either way the SNs don't have permission to update DNS.

[xcat-user] configfirewall postscript
Hi all, I'm trying to use the configfirewall from /install/postscripts to configure iptables on a stateful node. I added the script to the node's postscripts.postbootscripts, but it complains about a missing Perl dependency when executing.
