Hello everyone!
After the NCDC this weekend, we decided it would be nice to have a place to congregate and have informal discussion about the event, and about future events. We have started a channel on IRC at freenode. Details below:
Server: irc.freenode.net
Channel: #isucdc
Password: (currently no password)
Hop on and give your praises, express your concerns, and suggest improvements!
There has been many questions about the 20GB disk size regulation. Here is how it is stated currently:
Yes! This should be added to the scenario.
DNS will be scanned at ns1.siteN.cdc.com. Please add the name ‘ns1’ to your DNS records.
So the rules say that admins need to be able to sudo on the shell server. What do they need to be able to do?
Is the white team running an NTP server available to the blue teams to use? This would help us coordinate our logs, events and activities with white teams records of events.
Yes! An NTP server is now available at time.cdc.net, or 199.100.16.100 (the proxy server).
On Windows, right-click the clock, choose “Adjust date/time”, then click on the “Internet Time” tab.
On *nix systems, install ntpdate to easily synchronize with our server:
ntpdate time.cdc.net
You can also install an NTP daemon to sync automatically upon startup. See the documentation associated with your distro for more information.
Eclipse Classic is fine, or any version that can be used to develop Java.
ISU does not have a KMS server that licenses Windows Server installs. The ISOs we provided for 2008 R2 will be good for 30 days without entering a key. Just to verify this, I accessed your two active Windows VMs (RDP and your DC rebuild); both report that they are set to 30-day expiration. In the event that those do start complaining sooner, you can always re-arm as well using: slmgr.vbs /rearm
The script to test your shell server is now available from inside the ISEAGE network at http://blue.cdc.net/compile_test.sh
You can grab and run this easily via command line (assuming you’ve set up your network interface properly):
wget http://blue.cdc.net/compile_test.sh chmod +x compile_test.sh ./compile_test.sh
Please note the difference between the java runtime (java) and java compiler (javac), as you will need both to function correctly!
The script automatically generates and deletes source files to run its tests. If you’d prefer to use these files for troubleshooting, simply set the PRESERVE variable near the beginning of the script to 1.
If you’d like to examine it on your local machine, it is also available here: compile_test.sh_.txt Remove the “_.txt” ending before running it.
