Why does it say all my ports are closed?

Why does it say all my ports are closed?

As bill001g stated, all ports are closed by default unless a program tells Windows ( and/or your firewall) to open them. You could try resetting your router, but another option would be to uninstall and reinstall one of the problem apps to see if they re-open the port(s) needed.

How do I trace a port on a tracert?

How do I use Tracert?

1. Open a Command Prompt.
2. In the Command Prompt window, type ‘tracert’ followed by the destination, either an IP Address or a Domain Name, and press Enter.
3. The command will return output indicating the hops discovered and time (in milliseconds) for each hop.

What ports need to be open for Traceroute?

The default is 33434. The traceroute command depends on an open UDP port range of base to base + nhops – 1 at the destination host.

What does it mean to run a TCP traceroute?

A TCP “traceroute” run to a domain on a specific port should give a good idea as to where the traffic is being dropped. A traceroute simply shows the ‘path’ on the Internet between the host where the traceroute is run and the destination that’s specified as well as where, if anywhere, the route is failing to complete.

What are UDP ports to open for UDP traceroute?

Linux/Cisco devices use UDP for traceroute, but the range of ports for that is quite vast (and random in case of source ports). It may be easier to just allow the appropriate ICMP messages through than to try to allow all possible port combinations for sending/receiving a traceroute packet.

Which is the traceroute command in Windows 10?

The traceroute command in Windows is tracert. On a Linux system, like Kali, the command is traceroute. A typical tracert on a Windows machine would look like the following. Tracing route to www.google.com [74.125.227.179] Trace complete. Many of the scanning tools on Kali make use of protocols like TCP, UDP, and ICMP to map out target networks.

How can I see traceroute details in nmap?

In the next release of Nmap, the scoring function that decides which port is used for timing and traceroute probes will prefer ports other than the commonly-spoofed ports of 25, 113, 135, 139, and 445. It would not help in your case, however, since closed ports are more strongly preferred than open ones, and 113 is the only closed port in the scan.
