    C2 - Error starting SSH server: listen tcp 0.0.0.0:2022: bind: address already in use

    You are right, I think 2 instances are running somehow. Also, I did not check my processes earlier when you mentioned it. Thank you again for your help.

    ubuntu@ip-X:~$ sudo ss -tulpn | grep 2022
    tcp   LISTEN 0      4096                                *:2022            *:*    users:(("c2-3.3.0_amd64_",pid=10519,fd=7))
    ubuntu@ip-X:~$ sudo netstat -tulpn | grep 2022

    Okay, I saved it and ran the following commands, but still showing an error, so I know I messed up somewhere. (Ubuntu 22.04.1 LTS)
     

    sudo systemctl daemon-reload
    sudo systemctl enable cloudc2.service
    sudo systemctl start cloudc2.service
    sudo systemctl status cloudc2.service

    ### /etc/systemd/system/cloudc2.service
    # [Unit]
    # Description=Hak5 Cloud C2
    # After=cloudc2.service
    # [Service]
    # Type=idle
    # ExecStart=/usr/local/bin/c2-3.3.0_amd64_linux -hostname http://x/ -https -db /var/cloudc2/c2.db
    # [Install]
    # WantedBy=multi-user.target

    What is odd is that I edited it and removed the http:// after host name. Before that, I had my IP in there and you showed me that -https would not work with an IP so that is when I registered the domain and added it into the service file.

    I want to be able to connect to C2 from anywhere to 3 devices that I have set up at my home network (packet squirrel, key croc, and screen crab). I do want to use HTTPS, but I don't think a domain name would not be required for what I am planning. Pretty much, I am just wanting to learn more and play around with the tech, mostly the packet squirrel, that will be at my house, where ever I am. Obviously I am using everything on my own networks. I hope that helps and makes sense.

    All ports are open per the instructions followed and I'm using Amazon Lightsail VPS following the instructions posted. I cannot access with the domain name or IP address from a browser. When I use port 8080 I get ERR_CONNECTION_REFUSED but when I use the static IP It returns ERR_SSL_PROTOCOL_ERROR. When I enter the domain name into the browser it returns the same.

    When I run 'sudo systemctl status cloudc2.service', it shows http instead of https in the domain name after -hostname. I'm not sure if that's important or not.

    You are right on both. I used my static ip after -hostname in the second example and I think that messed up Let's Encript's SSL somehow. Also, I did already have a C2 instance in systemd which was cloud2.service. I edited the systemd service file to add new domain that I created yesterday. Now when I use "sudo systemctl status cloudc2.service", I get the following. (x & X are placeholders.)

    missing server name
    TLS handshake error from x:31579: acme/autocert: host "X" not configured in HostWhitelist

    I hope that makes sense. I don't now where to go or how to fix it and want to wipe it all and start over, but I feel like that does not teach me anything. Thank you again for your assistance.

    I need some help and would like someone to assist me. I feel like I followed the directions, but I messed up somewhere as I went to relaunch using "sudo ./c2-3.3.0_amd64_linux -hostname https://X/" (which worked before), the following is provided.

    [*] Initializing Hak5 Cloud C2 v3.3.0
    [*] Hostname: https://X
    [*] DB Path: c2.db
    [*] Initial Setup Required - Setup token: X
    [!] Error starting SSH server: listen tcp 0.0.0.0:2022: bind: address already in use
     

    Admittedly, I am at my knowledge limit, a bit lost, and not sure how to resolve this the correct way. I want to delete everything and start over, but wanted to see if someone here could help me first, lol. Thanks in advance!
