Constance, I have not tried to use OpenJDK instead of Sun Java, although I do plan to try this in the future. From my experience with other Java applications, I have not had any issues with applications that were written specifically for Sun Java that did not work with OpenJDK as well. Of course, as with anything, your mileage may vary.

Hey Ben, I had been going to write back and ask you about this very topic, so I am grateful you have sent this information my way. We are running VMWare ESX5. Question on the JAVA - have you tried both and found that the former works better than the latter? I ask because I was going to install the JDK. And thanks for the heads up information! :) Constance From: Ben Branch [mailto:bbra...@uco.edu] Sent: Friday, April 26, 2013 12:35 PM To: cas-user@lists.jasig.org<mailto:cas-user@lists.jasig.org> Subject: RE:[cas-user] [cas-users]: First Install of CAS - recommendations? Constance, Just as an FYI, my current TEST and PROD environments are both running on RHEL 6.4 (64bit) (TEST is on physical hardware, PROD is virtualized on VMWare ESXi 3.5). The only thing that is not standard on my systems are the version of Java that I am running (Sun Java 1.6.0_29 instead of OpenJDK Java ) and my version of Tomcat (Tomcat 7.0.22 direct from the tomcat.apache.com website). Just a side note about your network connectivity...even if you configure your nics with all of the proper information, if the port on the switch you are connected to is not in the proper VLAN, you will not be able to connect to anything nor will you be able to connect to the server. Be sure to consult with your network team and make certain that all of the infrastructure work has been provisioned before you move forward with testing connectivity to your CAS. I hope this helps...good luck! Ben Branch UNIX/Linux Administrator University of Central Oklahoma ITIL Foundation v3, Network+, RHCSA 100 N.

Hi Ben, I appreciate your in-depth response and examples. I will definitely follow them and write them down. What I was running into with both the RHEL 5.8 and RHEL 5.9 version installs - was that no network devices were being found. I would not have the files (ifcfg-eth0) or directories required upon installation for network configuration or access. Our technician who oversees our vmware found that a change needed to be made within vmware and once done - the system was able to locate my IP, MAC, etc. on its own, but I still had trouble connecting to the outside world. So our network administrator took a look and said something was wrong with my static address he had given me. He made some changes and both techs advised me to do a reinstall on the OS, but they said I should use something else besides RHEL like Ubuntu. My boss wants me to stick with RHEL and after seeing you also mention it in your email, I will. Thank you again Ben and have a great day!

Constance, I have used both CentOS 6 and RHEL 6 as the OS platform to install CAS on. I'm not sure what your exact network issue was over, but there are a few things in a default RHEL install that can cause you problems if you don't know what to look for. 1. Iptables/ip6tables - If you know how to configure them, make sure that you allow the right ports, otherwise this is going to cause you some issues with connecting back to your CAS after install. If you aren't sure how to configure iptables/ip6tables, disable and stop the services (chkconfig iptables off; chkconfig ip6tables off; service iptables stop ; service ip6tables stop). This will save you a great deal of headaches when you start your tomcat instance up and you are trying to figure out why it won't connect. 2. SELinux - Again, if you know how to configure and troubleshoot SELinux, make sure you set it up properly after you have installed it. If you have requirements that you MUST run SELinux, I highly suggest installing setroubleshootd (yum install setroubleshoot). This will create an audit log that allows you to see the exact SELinux error and how to resolve it. If you are unsure how to configure SELinux, make sure you set it to permissive mode. As a best practice, I do not recommend disabling SELinux, just my 2 cents on that issue though. 3. NetworkManager service - I despise this service. I recently ran into an issue where the NetworkManager service was disregarding my network-scripts and acquiring DHCP addresses instead of using the ones I had assigned statically. IMO, it's best to disable this service (chkconfig NetworkManager off) and configure your network using the network-scripts (ifcfg-eth# scripts located in /etc/sysconfig/network-scripts). Please note, YMMV with regards to your ifcfg-* script names. Depending on the hardware vendor you may get different interface names. I've seen the Dell 4 port 1GB daughter card show up as either interface em1 through em4 or as p1p1 through p1p4. Also, make sure you stop the service after disabling it, otherwise if you start making changes to your network scripts, the network manager will try to start using them instantly. This can cause you some issues if you aren't ready for your changes to go into effect. Ben Branch UNIX/Linux Administrator University of Central Oklahoma ITIL Foundation v3, Network+, RHCSA 100 N.

Hi everyone, I've created a virtual machine in vmware and have installed red hat enterprise linux 5.9, but ran into some problems with the network - which I may have straightened out now. However, due to those network problems (which may be resolved) - it has been suggested to me by my co-workers that I now do a fresh install, but that I use something other than red hat....like an Ubuntu server (which I have experience with also). For those already using CAS - what do you recommend.....Ubuntu server or something else? I have not attempted to install the CAS server download I got from the jasig.org/cas website yet but any suggestions or words of advice to get me going would be greatly appreciated. Thank you for your time!
