To install netutil in your system you must clone the repository, build the package targeting release and run cargo install.
bash
cargo install netutil
bash
$ netutil --version
As this is a cargo binary, you can easily uninstall the package issuing cargo uninstall --bin netutil.
netutil is a simple port sniffer tool, which helps to know which ports are open in a given range by attempting to open TCP connections.
To test a single address you must run:
bash
$ netutil 127.0.0.1:8080
This command will return an output similar to the following:
```bash
• 127.0.0.1:8080 - Open ```
This output means that the port 8080 is open in the IP address (local IP address), 127.0.0.1.
A set of ports can also be tested using the -r argument, which stands for "range":
bash
$ netutil 127.0.0.1:8080 -r 8100
The range is made from the
targetaddress port until therangeargument value port. In the case above the range would be [8080, 8100].
As a set of ports are going to be tested, a confirmation is prompted before initializing the task:
```bash $ netutil 127.0.0.1:8080 -r 8100
Are you sure you want to scan on 127.0.0.1:8080 from port 8080 to 8100? (y/n): ```
If no ports are available after executing the task, then a message like the following will appear:
```bash
No ports open in address 127.0.0.1:8080 for the port range 8080 to 8100 ```
Otherwise a list of available addresses is shown:
```bash
• 127.0.0.1:8080 - Open • 127.0.0.1:8084 - Open • 127.0.0.1:8095 - Open • 127.0.0.1:8099 - Open • 127.0.0.1:8100 - Open ```
```bash time cargo run -- 127.0.0.1:3000 -r 65535
Are you sure you want to scan on 127.0.0.1:3000 from port 3000 to 65535? (y/n): y Scanning on 127.0.0.1:3000 Open ports: • 127.0.0.1:5432 • 127.0.0.1:8080 • 127.0.0.1:47786 • 127.0.0.1:53708 cargo run -- 127.0.0.1:3000 -r 65535 5,14s user 10,79s system 165% cpu 9,601 total ```
