I have some things to ask
What is this Time_wait,Established under the STATE part after typing 'netat' ?
And why are there 'two' Local IP addresses ? Isn't my local computer supposed to habe one IP address only? << This is the biggest question.
thanks
Jump to Post127.0.0.1 is the 'loopback' connection. Anything sent to that never actually leaves your box.
TIME WAIT is just the state a connection enters after it has been closed, but before it is purged from your systems networking cache (in simple terms).

Jump to PostThe port number of the sending and receiving tasks are usually different. A server will listen on a known port, and when the client connects to it, it will provide an anonymous port to use for that connection.

That is what I am talking about (Above ) .Result of the netstat command
127.0.0.1 is the 'loopback' connection. Anything sent to that never actually leaves your box.
TIME WAIT is just the state a connection enters after it has been closed, but before it is purged from your systems networking cache (in simple terms).
thank you
what about the other Local IP? 10....
The other IP would be from the actual IP of your computer. So pretty much, you've got two networking interfaces on your computer, a virtual one (the 127.0.0.1) and the physical one (10.11.44.173). So, the ip configured to your phyiscal networking interface is 10.11.44.173 (I assume assigned by DHCP). If you are connected to any service on another computer via the TCP/IP prootcol suite, it will be listed there.
TIME_WAIT is equal to something like LISTENING ?
Isn't the port number of of Local address suppposed to be equal to the port address of the foreign address?
I am using a laptop with HSDPA modem. not LAN networking
What is the term Time Wait / Established / Listening means?? what are 127.0.0.1:1110 and 173.194.36.7:80 means?? please advise.
The port number of the sending and receiving tasks are usually different. A server will listen on a known port, and when the client connects to it, it will provide an anonymous port to use for that connection.
