The tilix.art SSH server does not run on port 22 like most other tildes. Connecting to tilix.art on port 22 will connect to the host machine that runs tilix.art and helixnebula.cc. Use port 2020 instead. If you are using the commandline ssh program, specify your port by using the -p 2020 argument. For example:

ssh -p 2020 user@tilix.art

If connecting with another ssh or sftp software, look for an option to set your port to 2020

You will be prompted for your password. You can add your public key to ~/.ssh/authorized_keys to automate login.

You can make login more convenient by adding an entry for tilix to your ~/.ssh/config. For example:

# log in with just `ssh tilix`
Host tilix
    IdentityFile ~/.ssh/private_key
    # requires the corresponding public key to be in your authorized_keys on tilix
    User user
    Hostname tilix.art
    Port 2020

# log in with `ssh tilix.art`
Host tilix.art
    IdentityFile ~/.ssh/private_key
    User user
    Port 2020

# see `man ssh_config` for more details
