OSCAR does update your /etc/hosts file, but it should always append to it and not remove any entries. Can you post your /etc/hosts file and explain further what you experienced? > * concerns about pfilter > > The default install put something called "pfilter" in -- I am > concerned this is going to affect my cluster network > performance -- I don't need any security since this is a > completely separate network -- I would assume most clusters > are physically separate, and I don't quite understand the > need for all this CIA-level security on the cluster network. > Is there a way to run with minimal cluster-side > filtering/firewalling??? If you don't want to use pfilter, you can unselect it during the "Select OSCAR packages to install" step. You can also uninstall it via the "Install/Uninstall OSCAR packages" widget, but this functionality is currently not working. You can just disable pfilter from starting on boot by running "chkconfig pfilter off" on the headnode and all your computer nodes and also by executing "/etc/init.d/pfilter stop". > * partition sparing? > > Is it possible to set up the initial install so that it > doesn't nuke the entire hard drive?

That is not possible, when you deploy an image it has to overwrite your HD - unless you have multiple HDs. > * sundry "Xauth" warnings > > when I do "cexec" commands I often get these Xauth warnings > from one or more or the results -- what are these, and how do > I do a bulk operation to fix it up on the whole cluster? > (btw, I did do a bilateral root login after installing each node) I would suggest a google search regarding what "Xauth" means. To prevent this message from showing up via C3 tools, you can run "export CS_RSH='ssh -x'" before your C3 command. This will disable X forwarding when C3 use ssh to connect to the compute nodes. > * tests failed? > > One or two of the tests failed if I remember, but now I can't > find where the file is that it mentioned. Where is the test > file? It might be a good idea to put all the log files in one place. Please re-run the test and let us know which ones failed. Also the message tells you exactly where to look for the log files. Cheers, Bernard Using Tomcat but need to do more? Need to support web services, security?
