Ensure that the node being deployed can fully resolve the name of the
management node and itself. In an earlier email, you showed
the result of resolving both of the hosts from the management node. The compute
node being provisioned needs to be able to resolve
names too.
If name resolution doesn't work, the getpostscripts.awk script will silently
fail.
That's the script that fetches the mypostscripts script. You can actually run
it from the Anaconda shell and see the results. If the
results are empty, then you need to look more closely at name resolution.
Note that the "root" for the installation is not / but '/mnt/sysimage' when
working under the Anaconda shell. So
/mnt/sysimage/xcatpost would be the place to look for the postscripts. Go to
that directory and run the getpostscripts.awk script by
typing ../bin/awk ./getpostscripts.awk. I think you'll need to export a couple
environment variables for the script to run
successfully. Look at what's done in the generated template file.
Something like "USESSLFOR.."
I noticed that you didn't have an IP address listed in the node definition. Is
there anything in the 'hosts' table? I would add the
IP address to the node's definition, then run "make hosts" and "make dhcp".
Finally, did you try adding 'wget' to the pkglist for the node? That seems like
the explicit way to ensure that wget gets installed
on the node. I would assume that Anaconda itself uses wget to pull the RPMs
from the master node, so I'm a little surprised that
it's not there somewhere. Did you do a global find command?

OK, I ran the wget command after installing wget:
wget -l inf -N -r --waitretry=10 --random-wait --retry-connrefused -e
robots=off -nH --cut-dirs=2 --reject "index.html*"
--no-parent -t 0 -T 60 http://10.125.40.6/install/postscripts/ -P /xcatpost
It downloads what I think are correct postscripts into /xcatpost, but there is
no mypostscript* files there. Also no
/var/log/xcat/xcat.log and nothing new in /tmp/wget.log.
How to get this to work without manually installing wget?

I fixed the typo and try to install wget in centos7.pkglist, but wget package
still doesn't get installed:
[root@node0800 ~]# wget -l inf -N -r --waitretry=10 --random-wait
--retry-connrefused -e robots=off -nH --cut-dirs=2 --reject
"index.html*" --no-parent -t 0 -T 60 http://10.125.40.6/install/postscripts/ -P
/xcatpost
-bash: wget: command not found
So I try the commands:
[root@master ~]# xdsh node0800 -K
Enter the password for the userid: root on the node where the ssh keys
will be updated:
/usr/bin/ssh setup is complete.
return code = 0
[root@master ~]# updatenode node0800 -P
node0800: Cannot download the postscripts from 10.125.40.6 for
node0800.palmetto.clemson.edu
<http://node0800.palmetto.clemson.edu/> check /tmp/wget.log on the node.
This is the centos7.pkglist file after I fixed it, attached. I would worry I
have a repo problem, but yum works from the node.

BTW, is the netmask 255.255.0.0 on networks table for 10.125 network or you put

I'm trying to get centos7 compute nodes imaged, I have a basic centos7

don't seem to run, starting with resyslog in postscripts.postscripts field. I'm
