Warpinator
Version: 1.8.3 Web: https://github.com/linuxmint/
There are tons of ways to send files to remote drives, but shuttling files from one device to another inside the same network isn’t always straightforward. But it can be with Warpinator. It’s developed by the Linux Mint project, but Warpinator is available as a Flatpak, so you can install it on any distribution with flatpak install flathub org.x.Warpinator . The app also has unofficial builds for Android, iOS and Windows, which you can find on its website.
By default, the app launches with Secure Mode disabled, as it uses the default group code Warpinator. To enable Secure Mode, all you need to do is set a custom group code that is at least four characters long. Now install Warpinator on other distros and devices on your network, and change their group code to the same custom one you’ve assigned to the first device. At this point, all the computers and devices in your network can see each other.
However, since Linux distros run a firewall, you have to poke holes in it before Warpinator can ferry files through them. Again by default, the app uses the 42000/tcp and 41000/udp ports to transfer files. If you’re using Ubuntu, you can allow these ports in its UFW firewall with sudo ufw allow 42000/tcp and sudo ufw allow 42001/udp .
Similarly, in Fedora use sudo firewall-cmd --addport=42000/tcp and sudo firewall-cmd --addport=42001/udp . In Fedora you have to then make the changes persist across reboots with sudo firewallcmd --runtime-to-permanent .
The Linux computers should now be able to transfer files without any issues. The main interface lists all the other Warpinator-equipped devices in your network. By default, the app prompts the recipient to approve the transfer, but this can be overruled from within the app’s preferences.
