SSH/Web acces unreachable from MacOS Ventura 13.2.1 to Ubuntu 20.04

ThinLinc

Hello all,

I am trying to set up remote access to my workstation (Ubuntu 20.04). I would be connecting from my MacBook running macOS Ventura 13.2.1.
I have successfully installed the ThinLinc server as when I run the commands

sudo systemctl status vsmserver
sudo systemctl status vsmagent
sudo systemctl status tlwebaccess

I do see “active (running)” on all of them, and I can ssh and web access from the workstation itself.
Unfortunately, when I turn to my Mac, and try to either ssh or web access, it doesn’t work: it tries to access for a while and then either “can’t open the page, server unresponding” for web access or “port 22: Operation timed out” errors show up. The ports 22, 53/tcp and 300/tcp are open.
I believe it is a firewall issue since the ssh works and the web access too but only locally. Maybe more ports are needed than the 3 I have mentioned?

Thank you for your time!

Hello,

Are the server and MacBook on the same LAN? If so, you probably need to allow the ports in the Ubuntu firewall

You can check if the firewall is enabled with:

sudo ufw status

If it it’s enabled, you can add rules to allow ssh and tlwebaccess :

sudo ufw allow 22
sudo ufw allow 300

Kind regards
Martin

Hello,

Thanks for your answer.
I believe they are since they have the same first number in their IP address…
My FW is active, and those ports were already open. I did still run those commands but am still unable to connect from the mac. :frowning:
Even when I disable my firewall the remote connection still can’t be made.

Thanks in advance! :smiley:

Okay, so even with the Ubuntu firewall turned off, the mac cannot reach port 22 or 300?

Is the firewall activated on your Mac that might be blocking outgoing connections? That should not be the default behavior, unless explicitly configured to do so, but might be worth checking.

“Ubuntu firewall turned off, the mac cannot reach port 22 or 300?” Correct
On my mac yes the fw is activated, but no outgoing connections are blocked. Even if I deactivate it (both fw are disabled then), I can’t reach the ThinLinc’s server…

Ok. Could you provide with me the output of the following commands.
Please format them with Performatted text (Ctrl+E).

On your Ubuntu server:

ip r s

and

ip a s

On your Mac:

ifconfig

and

netstat -rn

These commands will display ip address configurations for your network interfaces and routing information.

If you do not wish to disclose this information publicly, please let me know, and I will give you an email address you can send this to.

Hello,

The information you provided tells us that your Mac and Ubuntu server are not on the same network segment, and that the traffic between them will need to pass through routers to establish a communication path. There are most probably firewall(s) between these machines as well.

You’d need to talk to your network administrator / IT Helpdesk to find out if what you want to achieve is possible in your situation.

Kind regards,
Martin

Oh ok!
I am working at a National Institute laboratory so it’s not surprising that the “wifi” network isn’t the same as the Ethernet one…I will definilty go see a network admin for help on that :slight_smile:

Thank you again for your time!

No problem.

Don’t hesitate to open another thread if there’s something more we can help you with, have a fantastic day!

Martin
