Configuring macOS for Remote Access. You must enable Remote Login. Address and the corresponding private ports used by Screen Sharing and Remote Login. VNC is open-source remote access software. It has been around for many years, and the protocol has been implemented in a number of different software packages. It supports Windows, Linux and Mac OS X. Programs include UltraVNC, TightVNC, TigerVNC, and RealVNC.
First you need to determine the ip address or name of the machine you are running the webserver on. I'm assuming you are running the webserver on a mac since you tagged your post macosx athough the instructions are similar for linux machines. So, on your mac:. Open Terminal.app. It's under Applications-Utilities. Run ifconfig in the terminal.
That shows you all the network interfaces on the machine. One of them is the network your machine is actively connected to. If you mac is on a wired connection that should be en0. Make a note of the address after inet - that should be the address your machine uses.
Let's assume you discover it's 192.168.10.1. Verify that you can connect to that address from your server with nc -v 192.168.10.1 3000. You should see a message like Connection to 192.168.10.1 3000 port tcp/http succeeded!. If that doesn't work, see below. If it does work, hit ctrl-C to exit the nc session. Now try to connect on your client machine.
If this is a web app, you should be able to connect via the browser. For example, try If you are unable to connect to your application on the server's real address, that means your application isn't listening on that address. You will need to investigate how to change your application configuration to modify that behavior. Since I don't know what application you are running I can't offer any good ideas on that.
Saanthosh: Look into port forwarding on your router. That's what I was doing before I discovered OSX's internet sharing feature (which apparently has been available since at least OSX 10.6). I did localhost testing on a variety of mobile devices in the same room/network as my OSX dev machine, made possible by standard/small changes to router configuration (ie port forwarding). Other articles and SO threads provide info on router configuration. Ultimately, I'm in a new location now and have no access to the router, so instead I use OSX (High Sierra) internet sharing to achieve the same thing.
– Jul 14 '18 at 18:25. Basically, from firewall settings you can allow a certain application (e.g. Ruby) to accept incoming connections. Plus to allow access to the outside world (e.g www), you'll need to forward traffic to your internal gateway:port via your router settings.
Here's how to do this:. Mac-Sys Preferences-Sharing-Enable “Web Sharing” checkbox.
Mac-Sys Preferences-Security- allow your application (e.g. Ruby) to accept incoming connection. Open a port on the router (via 192.168.1.1) to forward traffic from yourwebip:port to a localgateway:port. E.g. From my Verizon's router settings - Port Forwarding - create rule: forward to local gateway (e.g.
192.168.1.4), custom port, protocol tcp, source=any, destination=3280, all connection types, forward to port = 3000. Now from the remote computer, open your browser to your web ip address (find via ) + destination port# above, e.g. 72.189.1, this will connect to your local 192.168.1.4:3000 Note: I'm running on Mac OSX 10.7.5.
As an administrator, you can control whether users can access other computers from Chrome. Users can set up remote access using.
This Chrome app lets them use a computer or mobile device (client) to access files and applications on another computer (host) over the Internet. Block Chrome Remote Desktop installation To block users from installing Chrome Remote Desktop, follow the same procedures you use to block them from installing any other Chrome app. Control Chrome Remote Desktop network settings To enable Chrome Remote Desktop for local area network or VPN users only, disable firewall traversal by setting the policy on Windows and Mac machines.
To disable firewall traversal:. Windows: Set HKEYLOCALMACHINE Software Policies Google Chrome RemoteAccessHostFirewallTraversal to 0. Mac: Set RemoteAccessHostFirewallTraversal to NO in /Library/Preferences/com.google.Chrome.plist. Block Chrome Remote Desktop hosts and clients To block users on your network from remotely accessing other computers using Chrome Remote Desktop, or to prevent computers on your network from being remotely accessed with Chrome Remote Desktop, black hole the appropriate Chrome Remote Desktop DNS entries on your DNS server. To black hole an entry is to configure your DNS server to reroute traffic addressed to the entry to an invalid IP address. This causes the server to silently drop the traffic.
To block users on your network from remotely accessing other computers using Chrome Remote Desktop, black hole the chromoting-oauth.talkgadget.google.com and chromoting-client.talkgadget.google.com Chrome Remote Desktop client DNS entries. To prevent computers on your network from being remotely accessed via Chrome Remote Desktop, black hole chromoting-host.talkgadget.google.com. Enable Chrome Remote Desktop hosts for managed devices only To let users remotely access managed (corporately-owned) devices on your network while blocking their access to all other devices:. Black hole the chromoting-host.talkgadget.google.com DNS entry as described above. Create an entry that routes Chrome Remote Desktop host traffic to a different DNS name than the one used by default.
Windows: Set HKEYLOCALMACHINE Software Policies Google Chrome RemoteAccessHostTalkGadgetPrefix to a literal to use a different DNS entry. For example, allowed-chromoting-host causes hosts to connect to Google Talk at allowed-chromoting-host.talkgadget.google.com. Mac: Set RemoteAccessHostTalkGadgetPrefix to a literal in /Library/Preferences/com.google.Chrome.plist.
For example, allowed-chromoting-host causes hosts to connect to Google Talk at allowed-chromoting-host.talkgadget.google.com. Create an entry in your DNS server that maps the DNS name from step 2 to the IP address for the base talkgadget.google.com domain. Enable Curtain Mode for Chrome Remote Desktop. Note for Windows users: This feature only works on Windows devices running Windows Professional, Ultimate, Enterprise, or Server. To enable Chrome Remote Desktop to prevent someone physically present at a host machine from seeing what a user is doing while a remote connection is in progress, set the RemoteAccessHostRequireCurtain policy on Mac machines. What this does is block anyone physically present at the host machine from seeing your actions on the device when you’re remotely connected.
Learn more about Curtain Mode under. Steps for all Windows installations. Note: The parent keys may not exist (even with Chrome installed) and will need to be created. The '1' is of type DWORD-32. Set HKEYLOCALMACHINE Software Policies Google Chrome RemoteAccessHostRequireCurtain to 1.
Enable RDP connections to the machine by selecting Control Panel System and Security System Remote settings 'Allow connections from computers running any version of Remote Desktop (less secure)'. Additional step for Windows 10 installations: Follow the steps above for all Windows installations, and then do the following after step 2: Set HKEYLOCALMACHINE SYSTEM CurrentControlSet Control Terminal Server WinStations RDP-Tcp SecurityLayer to 1. For additional information on this key and value, please see on the Microsoft Windows Server website.
