检查空口令:
[code]awk -F: '($2 == "") { print $1 }' /etc/shadow[/code]
正常执行后应该没有任何显示.
如果是发现有输出显示的话就证明这个用户没有口令.
执行例子:
[code]root@testpc:[/root]awk -F: '($2 == "") { print $1 }' /etc/shadow
test
root@testpc:[/root]cat /etc/shadow|grep test
test::13251:0:99999:7:::[/code]
检查tcp/udp所有监听的服务以及进程名称:
[code]root@testpc:[/etc/pam.d]netstat -tulp
