/proc/sys/net/core/rmem_max PERMISSION DENIED

[SunWupen]

Every time I try to run this command "/proc/sys/net/core/rmem_max" I get a Permission denied message.  I tried it using "su" and I've even gone as far as switching to Root (I know, I'm not supposed to...) but this command seems to be stubborn.  I don't know how to give myself permission to tweak my TCP/IP parameters.

I think I seem to remember having a "permission" problem with one of my other programs.  I don't remember how I solved it v(-_-)v

That is not a command, it is a path to a virtual file meant to be read as a text file, type the following command on the terminal to see what it contains "cat /proc/sys/net/core/rmem_max"

"/proc" is a virtual file system meant to provide runtime information of the system and running processes in a form that can be accessed as if the information is contained in regular text files.

what exactly is the problem you are trying to solve?

I guess I just didn't understand the command from speedguide.net.  I'm trying to maximize my TCP buffer size (I think).  I heard that changing a few things with the TCP can increase speed ten fold.

Ultimately, my goal is to be able to host online matches with a few games I own.  My current settings are fairly slow and I can't host many players without serious lag issues.  I know part of it is my ISP which there isn't much I can do about, but I want to change things where I can to maximize my connection.

a bit of googling and i came up with this article: http://www.speedguide.net/read_articles.php?id=121

as this article shows, one way to modify the variable you want to is to use the "echo" command and a redirect to the path to the file but this option will not survive reboot, the permanent way is to add the options in sysctl.conf file as directed in the article.
