[techtalk] Kernel params

[Kathryn Hogg]

Can someone point me to documentation on the available linux kernel
params and how I go about querying and modifying them?  It appears that
I'm either hitting the system limit for open files or the user limit. 
"lsof | wc -l" tells me that I have 2843 open files at the moment.

And another thing, what is udpd?  It appears to be a udp version of tcpd
but I can't find any documention or where it might be referenced.
