Netcat 传文件速度测试

1.*nix
A.nc -v -v -l -n -p 22222 >/dev/null
B.time yes|nc -v -v -n A_ip 22222 >/dev/null
或者dd if=/dev/zero bs=1M count=1000 | nc A_ip 22222

A.nc -n -v -l xxxx < testfile
B.time nc -n -vv -w2 A_IP xxxx > testfile

2.*nix
A.nc -l -p 77777 > /dev/null
B.pv -b -r /dev/zero | nc 192.168.1.1 77777

3.for windows
Win:nc -n -w2 -l -p 55555 > file
Linux:time /usr/local/bin/nc -n 192.168.1.118 55555 < file

注意：nc必须是编译版，pv需另外安装
