Permission issues using file_puts_contents on /etc/hosts

[sirolad]

Because I use sudo to access my /etc/hosts file, writing to it from line 133 is returning permission denied. Is there a way around this without 'chmod-ing' my hosts file?

[kilroyweb]

I had to play around with permissions a bit as well so I'm not too sure of a perfect solution.

I'll keep this open for now though in case anyone else has any good ideas since I'd also like to get some good documentation in place for any prep needed to the hosts file.

sudo chmod 664 /etc/hosts works for me on Mac.
Once you make it writable by the wheel group ( of which most admin users are a member ) you'll have permissions to write to it. Should only have to do it once.

@TTiger better solution than mine, I was just sudo homeboy'ing to get it working.

Thanks all, I think it's pretty safe to close this for now since it's more of a platform / permissions related issue.

I made a small note in the Troubleshooting section of the ReadMe with the chmod settings from @TTiger

Please note that adding more permissions to /etc/hosts may make your system vulnerable to DNS hijacking attack since /etc/hosts is preferred over any DNS server

Better solution would be to trigger sudo prompt, maybe something bit like this

<?php

namespace App\FileManagers;

class HostsFileManager extends BaseFileManager {

    public function appendLine($line)
    {
        // Do we need to sanitize these variables? Probably yes
        return exec('echo "' . $line . PHP_EOL . '" | sudo tee -a ' . $this->filePath);
    }

}

(Only works for Linux and OSX)

Thanks Kehet, I'll keep this open for now and see if we can get an update in place for Linux/OSX

and I'm back using sudo homeboy, with sudo it works like it should, but is not a good thing to do.
