1

2) count the number of httpd connections

PS-Ef | grep httpd | WC-l

Netstat-Na | grep established | awk '{print $5}' | awk-F: '{print
$1} '| sort | uniq-c | sort-R + 0n

'{Print $1}' | sort | uniq-c | sort-R + 0n

Man netstat can be used to understand the significance of syn_rcvd. Syn_rcvd indicates the current unfinished tcp syn queue

Run the following command:

# Netstat-an | grep SYN | WC-l

$ Netstat-an | grep syn_recv | WC
