The project is mainly to test whether a server can build one million connections simultaneously. The result shows that it is unfair to judge a server by only considering its concurrence.
1、Modify some configuration settings of your machine.
In client machine:
1.1
#vi /etc/sysctl.conf
net.ipv4.ip_local_port_range = 5000 65000
1.2
#vi /etc/sysctl.conf
fs.file-max=1100000
fs.nr_open=50000
1.3
# vi /etc/security/limits.conf
* soft nofile 55000
* hard nofile 55000
In server machine:
1.1
#vi /etc/sysctl.conf
fs.file-max=1100000
fs.nr_open=1100000
1.2
# vi /etc/security/limits.conf
* soft nofile 1010000
* hard nofile 1010000
2、You should assure that you machine is in a Local Area Network. And modify the multi_ip.sh to configure 50 IP addresses for your client. You can use "ifconfig -a" to see 50 ip.
Compile and run two ".c" file. First run server and then run client. And you can see the result by using command:
watch "ss -t -a |grep ESTAB |wc -l"
