Patient: "Doctor, it hurts when I type ``nmap -sP 172.22.0.0/16''!!"
Doctor: "Don't type that."
Patient: "Oh, ok..."
The system will panic with an 'out of mbufs' message when I run the above
nmap command ("ping scan" a class B subnet - my internal IP network).
Should this be happening when run as a normal user?? The kernel is pretty
stock with maxusers 32, no NMBCLUSTERS option, unneeded devices removed.
There is 64M RAM and 256M swap; it is has dual 90MHz P54C's.
This system (my workstation) is a:
FreeBSD 3.3-STABLE #0: Mon Sep 20 09:44:35 EST 1999
I am:
bash-2.03$ id
uid=1000(andyf) gid=1000(andyf) groups=1000(andyf), 0(wheel)
I have:
bash-2.03$ limits
Resource limits (current):

memoryuse 65536 kb
memorylocked 8192 kb
maxprocesses 256
openfiles 256
I use:

How would you go about preventing this problem?
Thanks.
