0.0.0.0:80 what does this mean?
I have an Embedded device.
It basically uses the Linux as a OS .
It works as a modem i.e having a wan interfaces and lan interfaces .
I Connect my PC to that Modem .
Now that modem becomes a router to me .
i can access that router using the g/w address ex: 192.168.1.1
Now when i type the netstat -aln in that device
i get the following information
tcp 0 0 192.168.1.1:139 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:2420 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:53 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:4567 0.0.0.0:* LISTEN
tcp 0 0 255.255.255.255:5819 0.0.0.0:* LISTEN
1) here my first doubt is the http service is not running on the 192.168.1.1:80
it is running on 0.0.0.0:80 eventhough in my pc browser if i type the
192.168.1.1 how does it access the webservice.
2) what is this 255.255.255.255 ip ?
please guide me in understanding this network .
