Consider you have a network that you know nothing about. if you have

Naim, this may or may not be helpful but I wrote this bash script a while
ago to establish which ip's were active on my class C network:
The code is:
#!/bin/bash
pingEm()
{
echo "preparing pings"
for((i=1;i<255;i++))
do
echo "ping -c1 192.168.0.$i > $$/$i &" >> pingEmAll.$$
done
echo "start pinging"
chmod +x pingEmAll.$$ && `./pingEmAll.$$`
}
findEm()
{
for((i=1;i<255;i++))
do
awk '/64 bytes from /' $$/$i > ans
awk '{ print length($0) }' ans > len
if [ `more len` ]
then
echo "$i is on the network"
fi
done
}
mkdir $$ && pingEm
findEm
rm -r $$ & rm pingEmAll.$$ ans len
echo End of story
The output looks like this:
$ ./findIps
preparing pings
start pinging
1 is on the network
3 is on the network
7 is on the network
160 is on the network
240 is on the network
End of story

Anyway I will tell the user to stop his chat thing. Timo, there are chats out there which may behave less, uh, poorly than this particular one. There's perl-chat, an old one that I adapted myself once. Also you might suggest they look on sourceforge.net which in my experience has good software available all open source.

Jeff, do you think that the apps are trying to flock the file? I'm curious what the app level issue is and how it could be done properly -- being more of a developer than sysadmin. PHP is the single biggest cause of shared server problems at my company. I wish the PHP CGI stuff worked right, as if it did, we would opt to use that instead of the Apache PHP module. It may be slower, but at least that would limit what users can fuck up with third-party PHP scripts. :( How do you find the stability of Apache mod_perl?
