Using connectd in P2P initiator mode on macOS and Linux

Note

This guide describes the use of the connectd daemon on the initiator device so that you can incorporate remote.it P2P connection initiator functionality into your own programs.  If you simply wish to use remote.it P2P connections, we suggest that you download and install the Desktop Application.

 

Download the connectd daemon

The connectd daemon is used on your target device to enable remote.it Services. The same connectd daemon is used on the initiator device, on the client side of a P2P connection, although in a different mode, in order to connect to those Services.

The commands below show you how to use the macOS console to download and run the connectd daemon on a computer running macOS. Although this example is for the macOS version of the daemon, we have many other versions of daemon available.

# Download the most recent release (this is for OSX)
curl -LkO https://github.com/remoteit/connectd/releases/download/v4.8/connectd.x86_64-osx
# Make it executable
chmod u+x connectd.x86_64-osx
# Move to a folder on your PATH
mv connectd.x86_64-osx /usr/local/bin/
# Add a connectd symlink to point at the daemon
ln -s /usr/local/bin/connectd.x86_64-osx /usr/local/bin/connectd
 

Quick install for Linux systems

Please follow these instructions to download and install the connectd daemon on any Linux system. This also takes care of creating a connectd symlink.

 

Run connectd Network Diagnostics

To confirm that you have the correct connectd daemon for your device and its OS, and that your network is configured correctly to allow a remote.it connection, run connectd -n at the command line in order to run remote.it Network Diagnostics. You may have to configure any virus checker that you are using in order to allow connectd to be run. The output from connectd -n should be similar to the following:

This router preserves ports, this is optimal.
This router doesn't remap new connections to new ports.
