Right... And all the times you actually need to alter those values? Wouldn't it be better to document it in the first place, so one could _plan_ the system setup?
Example: Setting up a firewall with four interfaces on a network with some <= 40 concurrent users with linux 2.2, ipchains, and masquerading. Firewall's hardware is intel p75 with 48MB ram. In high-traffic situations, the firewall starts dropping packets excessively. After some thoughts about this, I dig into the kernel documentation. After increasing /proc/sys/net/core/netdev_max_backlog to 1500, hoping this could be equalient to MAXIMUM PACKET RECEIVE BUFFERS in netware, the problem is reduced dramatically.
I am really looking for what the /proc/sys is in detail. It is _not_ well documented anywhere, and if Linux should be able to compare with the big boys, there should be as few 'secrets' left for the kernel hackers.
Please CC: answers to me as I'm not on the list
