got duplicate tcp line ???

2025-04-15

When i run this command and see this

Code:

root@server [~]# netstat -n | grep :80 |wc -l
warning, got duplicate tcp line.
warning, got duplicate tcp line.
warning, got duplicate tcp line.
warning, got duplicate tcp line.
warning, got duplicate tcp line.
    576
root@server [~]#

is there something wrong with my /etc/sysctl.conf ? Any idea? thanks
