Remote access to Linux server (Ubuntu 16.04.3)

[Metallus97]

Hey,

 

I am running several Ubuntu servers at the moment to fold on them. SSH works as always, but can someone explain to me how to set up the firewall on the server and at home... I need tcp 36330 in and out to be free for my IP at home... that way I can monitor the Servers MUCH more comfortably 

 

THX!

Easiest way to setup firewall in terminal environment imo is UFW.

sudo apt-get install ufw

sudo ufw allow 36330/tcp

sudo ufw enable

You need to enable port forwarding on your router in its firewall settings.

 

Do note some ISPs don't allow port forwarding, some even charge you a fee for each port you want open. So do be aware of this moving forward.

kk, I will try this. To keep SSH (when SSH goes down I am fed)

I have to ufw allow 22

right?

Well now I'm confused as to what the goal is. Are you trying to modify the server with an application or are you trying to connect to the server from outside the local network?

Levent's got you covered if the former is the goal.

Port Forwarding is what you'd want if the latter.

Sorry! Let me explain better

I rented a linux server and want to connect to it via a monitoring app. The calculating program on the server "FAHClient" has a build in Server wich outputs stats (on Port 36330) from home I now want to connect to that port to monitor my application on the server.

Oh, you're renting a server. If the monitoring program is already running/configured then you'd want Port Forwarding on the router to connect to it.

 

That complicates things. I don't know how most hosting services govern requests to open ports. I would imagine they'll let you but probably not for free.

Yes the program is awaiting connection on the server.

Hm someone did get it working on Google Compute engine... there you can manually set up your rules, but I did not have luck with that either... help there would also be nice. 

I also have some cherry servers but no idea how they handle this. Lets first care about Google Compute engine.
