I am hoping to use ThinLinc to connect to a Linux Mint computer that is offsite. I have run into 2 problems. 1: When I try to login from a Windows PC on the same network as the Linux Mint PC I get the “Welcome” screen, when I click OK it terminates my connection. 2: When I try to login from a PC outside the network that the Linux Mint PC is on I get a “Connection to server timed out” message without a connection. I would really appreciate any assistance you could give me on these issues.

Hello @Lorick 1. Make sure that the user you are trying to login as with ThinLinc is not already logged in locally on your Mint server. If it is, you’d have to logout that local graphical session first. Many modern Linux distributions does not work well with multiple sessions for same account. 2. I’m missing information about your setup, is this at home? If it is, there are some configuration that has to be made to be able to reach your Mint server if it’s located on the LAN. Port forward has to be setup in your router/firewall and SSH tunnel needs to be created. This has been resolved in other posts on the community, please see > [@My personal ThinLinc use case and some performance comparison](https://community.thinlinc.com/t/my-personal-thinlinc-use-case-and-some-performance-comparison/173#suggestions-6): > > Hi there! My name is Andre, I’m undergraduate in Mathematics/Teaching, working as a Computer Technician at Universidade de São Paulo - Brazil and I’m here to share my Thinlinc personal use case.

Regarding the message " Connection to server:“192.168.1.6” timed out. Check your settings." is due to fact that Thinlinc VSMServer will instruct your Thinlinc client to make a second SSH connection to the ipaddress of your server, which is 192.168.1.6. Your client machine must have some way to directly make a connection to this address, and since it’s an internal address, we can… Best regards, Martin ---

I added the LOCAL Host information in the registry. I am now able to connect when on the LAN that the Thinlinc server is on. I am still unable to connect to the Thinlinc server from outside the LAN. Connection times out. ---

Hello @Lorick If I’m not misunderstanding things here, you were already able to connect to your ThinLinc server from LAN in your first post? But got disconnected? Did you verify / test my suggested solution? Im not following what you mean by > I added the LOCAL Host information in the registry. Regarding not being able to connect from outside, it usually involves setting up port forwarding in your router, and also setting up an SSH tunnel on the client before connecting to ThinLinc, as per mentioned in the other forum posts I provided links for.

Does your Mint machine have a valid IP Address? How would you connect to it using SSH? Can you connect to it using SSH? If your machine is under NAT and you’re using something like SSH Tunnel to reach your machine, you should configure the HOST\_ALIASES parameter on your client computer just like me (and Martin mentioned the topic [My personal ThinLinc use case and some performance comparison](https://community.thinlinc.com/t/my-personal-thinlinc-use-case-and-some-performance-comparison/173#suggestions-6)) Another option would be to setup split DNS on the network where your machine is located. I think that setting up HOST\_ALIASES on your client machine is way easier.
