Why Does

Troubleshooting "sudo go run main.go" Error

When attempting to execute "sudo go run main.go" to capture network packets using "gopacket" on Ubuntu 16.04, you may encounter the error message "exec: go: executable file not found in $PATH." This error arises because the necessary environment variables are not set for the root user.

Solution:

Instead of using "sudo go run ...," follow these steps:

1. Compile the Binary without sudo:

Use "go build" to compile the main.go file into an executable binary. For example:
```
go build
```
Copy after login

2. Run the Binary with sudo:

Execute the compiled binary with sudo. For instance:
```
sudo ./mycapt
```
Copy after login

Alternatively:

Use "go install" to install the binary into your system's $GOPATH/bin directory.
```
go install
```
Copy after login
Then run the binary with sudo from the $GOPATH/bin directory:
```
sudo $GOPATH/bin/mycapt
```
Copy after login

By compiling and running the binary separately, you ensure that the necessary environment variables are available to the root user.
