According to the web-interface on port 8080 tomcat is running fine. Basically, I want to allow a Java program I have written (which works well) to be run over the internet. This is to test students understanding of Turing machines. The student has to enter a short program (consisting of 20-80 quadruples). My program will then test if the program does what it is meant to do. So the student enters his program (about 1k), eg by pasting from a file - the program should then run, and the student should see what it outputs. I'm looking for advice on the best way to set this up. As I understand it, tomcat can either be run standalone or behind apache. I am running httpd on the server, so either method should be available. It seems that the standalone option is simpler, so I would probably prefer that. On the tomcat side there really isn't any difference. The reason you would run behind apache would be to permit running all http connections over port 80, while letting apache handle some URL's internally and proxying other paths to other programs.If port 8080 is open and you don't need to restrict access to other tomcat apps you might as well go direct. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I did all the work on this back then, or maybe before and copied from my earlier server. This time I am trying to build everything clean and document every change I make. Such a misbehaviour would be caused by a misconfigured apache proxy setup. It is coming back now through a pair of dark glasses. Just haven't built a public web server is so long, as the old one just ran for as little as I needed it, that I lost the notes on the problem. Looks like current defaults do not allow this. Wouldn't this attack be similar to using someone's web server as a proxy to get to other sites? By default, apache doesn't permit itself to proxy this way. Not anymore. Once upon a time, the internet was a nice place and so what if you proxied?

I just wonder if this is an artifact from having started with an mp3 rather than a proper wave file? I finally figured out what the problem was. I started audacity at the shell prompt with the name of my wav file as a parameter. After doing more searching, I found that audacity will not allow edits to an original file. So I started audacity without any parameters, opened the wav file, and saved it as a project. I was then able to edit it. I just wish that audacity warned me that I was in readonly mode. Otherwise everything else about it was pretty intuitive. Thanks for all of the suggestions! c ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Google Earth on EL6.x x86_64
Has anyone gotten 64-bit google earth to run on el6 x86_64? It dies almost immediately, complaining for lack of ld-lsb.so.3.

[CentOS] Lockups with kernel-2.6.32-358.0.1.el6.i686
I updated my home server with the 6.4 CR packages, and I've experienced 3 or 4 hard lockups since. The server is a fanless VIA C7 CentaurHauls system with a 1GHz CPU underclocked to 800MHz and 1GB of RAM. It has a dual-port Intel 82546GB NIC in its single PCI slot. (It also has an on-board Realtek RTL-8110SC/8169SC NIC that is plugged in, but doesn't currently have an IP address configured.) This server provides a number of services -- DNS, DHCP, routing between VLANs, DLNA media server, CUPS, etc. Most importantly, it runs Asterisk and manages all of the phones in the house. There's absolutely nothing in the logs related to the lockup. The system simply becomes totally unresponsive, to the point that the console cursor stops blinking. A hard reset is required to bring it back. kernel-2.6.32-279.22.1.el6.i686 seems to be completely stable. I don't really expect to be able to figure this out, but I thought I'd post here to see if anyone else is experiencing anything like this with this kernel.
