-==> The installv2.sh script is not necessary if you are using the virtual machine version. This is intended to those that
-want to install the system as the host of a computer, or desire to create again the virtual machine version from the beginning.
-
-The script installv2.sh available here was used to create the "ICPC Linux" image after a standard installation
-of the ubuntu (or xubuntu) distribution. This is well-suitable in case you do not want to
-use the virtualized version, for example, in the server of the contest. After using the installv2.sh script over a fresh
-install of the ubuntu, you reach the exactly same content of the virtual machine version that is available. 
-Take care with the following points during the installation of the ubuntu:
-1) Use the name "icpcadmin" and password "icpcadmin" (no quotes obviously)  as the standard user during the installation.
-2) Call the machine "icpc" (in the same screen where you set up the username above).
-3) Use the simplest partitioning option (that is, everything in a single partition) and choose at least 10GB for it.
-
-After installing ubuntu, the system reboots. Download the script installv2.sh to the home directory of icpcadmin,
-make it executable by chmod 755 installv2.sh, and run it as root: sudo ./installv2.sh
-and reboot the system to finish the configuration (such as setting passwords, IPs, etc).
-Note this is going to give you a system just like you would get from the box (the virtual machine version). If you
-want it to become a server, you must follow the same procedure that is indicated in the READMEvm.txt. This
-mainly means that you need to run the script /etc/icpc/becomeserver.sh
-
-The most recent installv2.sh script is available at http://www.ime.usp.br/~cassio/boca/ link named installv2.sh
-In case of any questions, do not hesitate to contact me: bocasystem@gmail.com. Have fun!

-READMEvm.txt file of the ICPC Linux VM (release 2011)

-This file concerns the ICPC Linux image available in this directory. It is a vmware-type
-hard-disk image with a system built up over a ubuntu (or xubuntu) distribution. This is
-also relevant if you have used the installv2.sh script to build the server natively, as the
-system will have the exactly same characteristics of the VM version mentioned here.
-
-- You need the vmplayer from www.vmware.com to use this image. As far as I know, vmplayer is
-free-of-charge for linux and windows hosts. Check it. There is another version based on virtualbox,
-which is just a translation from the image here. virtualbox is free and works pretty well too.
-
-- Internet access is restricted inside the box. By default, users can only access 
-bombonera.ime.usp.br, the home of BOCA. During the first boot time, you are able to choose a
-different IP address of your server instead of bombonera. If you are going to run a contest,
-you must do that! The system inside the virtual machine (or just VM) will
-only be able to access such server and nothing else. An alias with the name boca is created
-for such IP, so it is possible to connect to it using the name boca instead of typing the
-IP address. So, during the first initialization of each VM you should configure the IP address
-of your BOCA server. The image provided here can be used as a BOCA server too. See next bullets
-on how to do that. In the team machines, check if the internet is really blocked. If not, the
-initialization scripts might be malfunctioning, or the computer might be mistakenly set to be
-a server (this can be easily checked by verifying whether the file /etc/icpc/.isserver exists or not).
-
-- There are two linux users in the box: icpcadmin, which has right to become root using
-sudo, and the user icpc. The latter has password icpc, and more restricted access. The user
-icpc is intended to be used by the teams, judges, staff, or anyone else. The icpcadmin is 
-an administrative account and the password must be known only by the sysadmin, director of the
-contest, and so on. During the first boot time, you are able to change the password of the icpcadmin
-account. DO IT and keep it safe! The default password is icpcadmin. Note that such
-users (icpcadmin and icpc) have nothing to do with users of the BOCA web system. Each
-team must have a distinct user to login on BOCA, which are configured through the BOCA web interface.
-Still, each team will logon into the linux box using the same user: icpc. As mentioned, this is
-not a security problem because the user icpc is just a local account in the linux system without
-any privileges.
-
-- To run a contest using a virtual machine, you probably need at least 384MB of RAM inside a 
-"good" computer (then you can configure the VM to run with 256MB). I have tested the vm image
-configured to use 512MB. If your host has for example 1GB, you may change the vmplayer 
-to use 768MB, although 512 should be fine too. Just keep some room for the underlying operating 
-system. Using more memory inside the vm is better for the teams, so they can run heavier tools.
-
-- Unzipped, the image takes around 12 GB of your hard disk. You need this space in the hard
-disk of each computer. If this is a problem for you, it is possible to rebuild the vm system
-with less space (8GB for clients is enough, the server has to have more).
-
-- It is possible to maximize the VM window so as it uses the whole screen area. The current
-image is set to 800x600 or 1024x768 pixels, but that can probably be increased depending on your 
-video card and monitor settings. The keyboard config can also be changed
-inside the x-window system configurations.
-
-- During the first startup, an script will ask you for the BOCA database password (after 
-asking the BOCA server IP address and password of the icpcadmin). YOU MUST ONLY FILL
-SUCH PASSWORD IN THERE IF the machine being configured is NOT going to be used by a team. With
-this password, it will be possible to access the database directly (instead of by web). Teams
-shall access the system only by using the web interface. This password is intended to be used
-in the machine that will have the autojudging system, as the autojudging script needs to 
-connect to the database directly (see next item about the autojudge). In fact only the
-autojudging machine (or machines, if you have more than one) need this password to be set.
-
-- An autojugding machine is used to automatically compile and execute the codes submitted
-by the teams. DO NOT run it on the same computer as the BOCA server (the web server and the database
-server). Because teams may submit malicious code, it is safe to run it on a separate computer.
-The worst scenario (in case a team's code hangs the computer) will require to reboot such 
-computer. About the configuration, the only difference between the autojudge computer and 
-team's computers is the setup of the database password, as mentioned before. You must set up
-the database password during the initialization of the autojudging computer. Then, to run the 
-autojudging system, you need to login as icpcadmin (privileged user), open a command-line 
-terminal (it is inside accessories), and run "sudo /var/www/boca/tools/autojudge.sh" (without quotes).
-If everything is fine, some dots will appear on the screen while the script runs an infinite
-loop waiting for submissions. Ctrl-C stops the autojudge. The autojudging shall be started 
-after configuring the server to run the contest, otherwise it will eventually output an error or
-freeze. If you see the dots happening every few seconds, you are in the correct track.
-
-- With old versions of ICPC Linux, all the team files were kept in the server. Now this is
-NOT true anymore. Everything is stored locally. So, after a warmup and before the real
-contest, it is necessary to go to each team computer, open a command-line shell (you do not
-need to change to the privileged user, the unprivilegied icpc user is enough) and run 
-the command
-/etc/icpc/cleandisk.sh
-After that, reboot the system inside the virtual machine (not the host computer itself!) and you
-are done. All files belonging to the icpc user have been erased.
-
-- Because the files are stored in the local team computers, now BOCA (by web) has an option
-to make file backups, where teams can save their files on the server. Currently this must be done 
-manually by the teams (using the web interface of BOCA). There is a script available inside the
-ICPC linux (and inside the BOCA package) that teams may use to backup their files. To
-do that, they can just run "makebkp.sh". If they want to save other files, it is possible to use 
-the web interface of the teams. Note that teams should submit backup files with small size only, but 
-that is not a problem because source codes are really small. The script makebkp.sh is available 
-(but not very tested) which sends files .c, .cpp, .java and .in (it looks for these files in the 
-current directory) to the server. IT IS IMPORTANT TO LET THE TEAMS KNOW ABOUT THIS SITUATION AND
-THE POSSIBILITY OF SAVING FILES TO THE SERVER, EITHER BY USING THE makebkp.sh IN THE COMMAND-LINE,
-OR BY DIRECTLY UPLOADING THE FILES IN THE WEB INTERFACE.
-
-- The most complicated thing to run the contest using a VM is that you need to restrict the
-use of the host operating system. For example, it would be possible for a team to switch
-the window (from the VM to another program), and then use the internet (in case you have
-internet available in the host, which is usually true). I believe that the simplest approach
-to restrict the system is to impose a set of packet filtering rules in the host system, using
-a firewall solution. That would make the host system useless for the team. The only permission
-that the host must have is to allow connections to the BOCA server and (possibly) to the 
-authentication server of your network (in case it is needed to keep the host running. Better 
-if that can be avoided too). If your host is linux, then it is easy: you just need to include some 
-rules in the iptables (certainly a sysadmin knows how to do it).
-For windows (which is probably more usual and easy to deal with), there are many free-of-charge
-solutions. I do not know them well, but let me cite some: www.r-firewall.com,
-www.personalfirewall.comodo.com, tiny personal firewall (it is possible to find it online),
-perhaps the windows firewall can be enough (in some windows versions). NOW THE MOST COMMON /
-PRACTICAL WAY TO SOLVE THE PROBLEM: keep an eye on the teams all the time. Have some volunteers 
-looking the teams work on the computers during the whole contest. No one is allowed to leave the 
-VM and use the underlying system. If they do that, then simply expel them from the contest! 
-Give a warn of the possible penalty to everyone before starting and that is it. Quick and clean :D
-
-- Any vm can become a server for the contest, which in this case will be a BOCA server running
-inside a virtual machine system. To do that, you just need to login as user
-icpcadmin, become root using the command "sudo /bin/bash"
-and execute the script /etc/icpc/becomeserver.sh
-READ THE FULL TEXT BEFORE RUNNING THIS SCRIPT. THE VM MUST BE IN BRIDGE MODE (see explanation
-below). At this moment, you will be prompted to define the DB password or use a random one. After
-that, the IP address of this computer must be used to configure all other VMs (during those
-startup questions). 
-Some considerations about a server: more memory must be used for the server. Have a computer
-with enough memory and increase the memory of the VM. Also take care with the
-disk space. The current image has only around 1.6GB free (still, that must be more than enough). 
-Finally, note that to run the VM as the server, it must be configured to run in BRIDGE mode 
-with respect to the network interface, otherwise it will not be possible for other computers 
-to reach it. BRIDGE mode means that you must look in your vmplayer (whatever player you are using)
-to configure the network as in BRIDGE mode). You may need to reboot the VM. If after rebooting it
-and running the command-line program "ifconfig" you can see that the IP address of your computer
-is the same inside the VM and outside, you are done. Besides that, the underlying operating 
-system must have NO apache or postgresql running, nor
-any other TCP server in the ports 80 (http), 443 (https) and 5432 (postgres).
-Yet I point out that running the BOCA system in a server computer (without the VM) 
-is the mostly tested solution, but the VM version was used in many sites already. If you want to 
-run it natively, stop here and go to the xubuntu directory of bombonera.ime.usp.br to see the
-instructions. You will need a computer that you can format and reinstall.
-That is the simplest way of having a full ICPC linux server
-running apart from using the VM version itself, as explained here.
-
-- After having the server and clients running up, it is necessary to configure the BOCA
-web system. For that purpose, please follow the steps of the ADMIN.txt file in the doc/
-folder of the boca system. It is available in the BOCA package or inside the ICPC
-linux at /var/www/boca/doc/. There are some examples inside the bits/ subfolder.
-
-- Try to use the vm without fear. In the worst case, download it again and start again
-(or even better, keep a copy of the image without changes). Any questions, please
-do not hesitate to contact me: bocasystem@gmail.com.
-
-- If you need to update the BOCA system that is running in your server (with the risk of losing
-data in the database of BOCA!), then you may run the script /etc/icpc/installboca.sh
-If you need to update general scripts that are used in the system and were installed by the
-installv2.sh procedure, you may run the script /etc/icpc/installscripts.sh
-These are easy ways to update the system in case bugs are found and fixed.
