You should open this port on all the middle devices to work the communication from your PC to the Raspberry Pi. Let’s see how to set up VNC on the Raspberry Pi. This flexibility makes this option more prominent than others. RealVNC gives users the freedom to connect from anywhere. This allows you to connect Pi not only within the network but also over the internet. But, most of the new Raspberry Pi distributions come with ReavVNC, which supports cloud-based connections right in. Few products are free, and few are commercial. There is a variety of products available on the market. It’s a cross-platform remote desktop technology that can be used on most operating systems. Thanks for the other tip, but now that I know how to connect, it doesn’t change much for me to put the IP address or the server name.Virtual Network Computing is the obvious option when you work with Linux platforms. I think that with the default DNS configuration the router automatically lookups in the right place for the “servername” (or at least in a case like mine, where the server is inside the homenetwork).Īnd actually all my flatmates can access the server from their computer with no problems with the servername.Īnyway, I guess that maybe a firewall must be a bit complicated to be effective. Now you tell me that the problem was not the DNS of Comodo, but I do not understand you well. In my case the frustrating aspect was that I was going crazy disabling the firewall, creating rules, putting VNC as trusted app, turning off Comodo, and I had no chance to find a solution alone because I would have never guessed that the problem was that the DNS of Comodo have no idea of where to find “servername”… Mmm, that’s what I meant, it is a bit complicated to figure out all this for the average user. file shown above, in VNC you can now use the name “my_server” instead of the IP address.Īll of this assumes that the IP addresses in use on your network do not change. For example: 102.54.94.97 # source server 38.25.63.10 x. # x client host localhost name resolution is handled within DNS itself. Additionally, comments (such as these) may be inserted on individual lines or following the machine name denoted by a ‘#’ symbol. The IP address and the host name should be separated by at least one space. The IP address should be placed in the first column followed by the corresponding host name. Each entry should be kept on an individual line. This file contains the mappings of IP addresses to host names. This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # Copyright (c) 1993-2009 Microsoft Corp. You can now use the “name” instead of the IP address in VNCĬlick START, type “notepad c:\windows\system32\drivers\etc\hosts.”Įxample HOSTS. To add the IP address of your system to this file do the following Ĭlick START → RUN, type “notepad c:\windows\system32\drivers\etc\hosts.”Īdd the IP address and a relevant “name” after the entry starting 127.0.0.1 This file is found at C:\WINDOWS\SYSTEM32\DRIVERS\ETC. There is simple way around this - add the IP address of the system you want to VNC to to your HOSTS. The DNS service you set up for your network connection know about systems on the internet but know nothing about the systems on your local network. You would find the same issue with ALL internet DNS services. Unfortunately, this is not a Comodo DNS specific issue - this is just how internet based DNS services work. I hope that this will be solved in future releases of Comodo because it is really difficult to use for someone who does not know a lot about firewalls and internet. Now I tell the server to look for the IP address of the server, and I can access. Finally I discovered the problem: it is the DNS of Comodo, I had choosen to change my DNS with the ones of Comodo, so when I was telling to the viewer to look for “servername” the viewer was not able to access.
