Port ping windows 7

To be more precise ICMP type 8 echo message and type 0 echo reply message are used. ICMP has no ports! See RFC for further details. However, most modern computers don't have the "echo" service running, so performing "ping" using UDP port 7 instead of ICMP would not work. As others have already stated, in general pings are ICMP-based and have no ports. There is, however, such a thing as TCP Ping where, instead of the typical 3-way TCP handshake, only the first 2 steps are performed and the delay between is measured.

The source port is just an ephemeral random port. As a note, some network equipment also has this capability, such as Cisco ASAs using some of the newer operating system versions. Ping use not port but protocol. However, as a security consideration, this is often disabled.

A common quick test for seeing if a TCP port is open is using the telnet client on Windows. Nmap is a third party utility you can use on Windows and Linux to test open ports. You can verify this by using wire shark to capture traffic to see how these operating systems use troubleshooting tools. Sign up to join this community.

Specifies reverse name resolution be performed on the destination IP address. If this is successful, ping displays the corresponding host name. Specifies the length, in bytes, of the Data field in the echo Request messages. The default is The maximum size is 65, The echo Request message can't be fragmented by routers in the path to the destination.

The default is the default TTL value for the host. That wasn't of any help, alas. I figured that out myself, however. I'll describe how I did it after short description of what it is I need and why one may need it. Ping: this is reply by the machine on the network when request is sent to this machine's IP address. Why it is necessary: suppose you have multiple machines and you want to know if there is machine on the network with given IP.

That's when you use ping. Many network admins routinely use that and windows machines are their pain as these by default do not respond ping MS must be scared since infamous "Ping of death" You should be done. This box responds ping from this point on.
