If that's the case, you definitely don't want to execute it as root. It simply adds an extra layer of security.Īnother example is that the program may be infected with a virus. The point is that if there is a risk that the program could cause damage if executed with root access and the program does not need to be executed with root access to do what it should, then it is sensible to prevent it from being executed as root at all. If this happens you would wish it was not executed with root privileges.Īnd yes, I do know that you would need to add -no-preserve-root in order to make this particular example cause any damage, but that's not the point. Now, instead of executing rm -rf /tmp/mygame it will execute rm -rf /. Remember that C strings are NUL terminated. Now imagine that the 't' character gets corrupted by whatever reason (buffer overflows, bit flips, some programmer "testing a thing" and does not restore or whatever reason) and gets the value '\0'. There are tons of situations how executing stuff as root could go bad, but imagine that program or game stores some temporary files in /tmp/mygame and upon exit, the program executes something similar to rm -rf /tmp/mygame. I figured it would be a good idea to give an example. I like it so much that I am considering using this simple check in almost all future code. So the reason is likely simply that 99% of those who start it as root does so by mistake, and normally there is no reason whatsoever to run a game as root. This on it's own is definitely reason enough. Also, it is a network application with servers and client. Especially since these mods are made by users and out of Id Softwares control. It is likely just that all software have bugs, and running the software with root privilege makes bugs much more dangerous.īut a good candidate to cause issues is the QuakeC language used to create mods. Setting Up a Port Forward for Quake III Arena Server Quake III Arena logo in red sitting on a white background.I doubt there is any very specific pieces of code they have thought of. When you use Quake III Arena Server you might need to forward some ports in your router. The purpose of forwarding ports is to make a direct connection from the internet to Quake III Arena Server. Routers do not generally allow incoming connection requests from the internet. To set one up, go to your router's app/configuration page and navigate to the wireless settings.Make sure that you know these things before forwarding a port: Forwarding ports can work around this limitation. The TCP and UDP ports that need to be forwarded.Most routers have guest networks disabled by default, so there will usually be a page to set. We have free Router Detector software to help you find your router's IP address. It is part of our Network Utilities suite of tools and is free for you to use it. Forwarding a Port for Quake III Arena Server Otherwise, you can follow our guide Find Your Router IP Address. The easiest way to forward your ports is to use our Network Utilities software. List of Routers - Customized for Quake III Arena Server You can choose your router from our list to see exactly how to forward ports for Quake III Arena Server: Put the TCP and UDP ports that you are forwarding for Quake III Arena Server in the correct boxes in your router.įrequently you have to reboot your router for the changes to take effect.Put the IP address of your computer in the proper box in your router.Locate your routers port forwarding section.You can start by logging in to your router.The normal process for forwarding a port is: Since Network Utilities allows you to both forward and un-forward ports easily you can keep your network security maximized, and then forward ports only when you need them.Īlternatively you can do it by hand. But on Netgear routers they ask for your service name and theres no Wii on it. 1 - A cable modem (or some other type of internet modem, duh) 2 - A router (wifi router, combo modem/router, etc.) connected to your cable modem 3 - A computer to host the dedicated server, connected to router with ethernet (don’t use wifi) The computer, ideally, is one that is not being used extensively for other tasks. That is the process required to forward ports in your router for Quake III Arena Server. Well, Ill remember never to try to help you again.
