I have a LAMP stack running Fedora 12 and I am run the following instruction through the command line on the server:
netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
As far as I understand this should show me the IPs of the connected processes and how many connections per IP there are, correct?
I would need some help in interpreting the results. Out of 250 total connections, 140 don't show any IP (just a blank), 80 are from my slave DB, 20 are from IP 0.0.0.0 and only 10 are from what appears to be normal connections to the server.
My questions are thus:
1. What do the 140 blank IPs represent?
2. Why does my slave DB (MySQL) need 80 connections? Can this number be reduced? If so how?
3. What are 20 0.0.0.0 connections?
I apologise if this is a trivial question, but I am a relative newbie at this.
Adding part of the netstat -anp (just removed my servers IPs and had to trim because of post length limit):

Best Answer
You passed the
-aoption which includes processes that are listening, and Unix Domain Sockets. Try runningnetstat -anpwithout any of the filtering/formatting stuff and you will see the full output. The0.0.0.0almost certainly represent listening processes. The blanks are almost certainly domain sockets.Because there are 80 things connecting too it? Look at the full netstat output, and you will be able to learn a lot more. Without any more details nobody here can make any useful guesses. The number may be able to be reduced, again we would need more details.
