I am trying to connect to Crate, installed on an Ubuntu Server (without graphical user interface). Following the documentation I have made these changes: crate.yml: network.host: _site_, _local_ Environment Variable: export CRATE\_HEAP\_SIZE=2g Any idea what is wrong? ![image](https://us1.discourse-cdn.com/flex020/uploads/crate/original/1X/cbe566f45d4d916ca8af87c5bc1e7c0fb4676011.png) ---

Hi @cfi - Are you trying to connect from the same machine or from a remote one? - To connect from a remote machine you need to first create a user, that is allowed to do so. The default superuser `crate` is only allowed to connect from the same host also see [Create user — CrateDB: How-Tos](https://crate.io/docs/crate/howtos/en/latest/getting-started/create-user.html) - Is CrateDB running? ```nohighlight systemctl status crate ``` - Can you connect from the same machine (e.g. using `crash`) - Do you have `ufw` enabled? ---

Hi @proddata after several tries and the hints in these sites I finally got it running (before your response): > [@How can I connect from a remote server to a CrateDB node using crash?](https://community.cratedb.com/t/how-can-i-connect-from-a-remote-server-to-a-cratedb-node-using-crash/832/10): > > [mfussenegger](https://github.com/mfussenegger) If you change network.host it assumes that you’re using CrateDB for production and enforces some [Bootstrap Checks](https://crate.io/docs/crate/howtos/en/latest/admin/bootstrap-checks.html) to ensure CrateDB is suitably configured. When using the package-based setup flavor for [Debian or Ubuntu](https://crate.io/docs/crate/tutorials/en/latest/install.html#install-deb) or [Red Hat or CentOS](https://crate.io/docs/crate/tutorials/en/latest/install.html#install-rpm), the CrateDB startup script uses [Environment variables](https://crate.io/docs/crate/reference/en/4.6/config/environment.html#conf-env) from the /etc/default/crate file. or you set it in the console with e.g. export CRATE\_HEAP\_SIZE=4g I think we might need to adjust the notes a little: I am sorry that you have suc… > “Are you trying to connect from the same machine or from a remote one?” Yes "To connect from a remote machine you need to first create a user, that is allowed to do so. " That was the problem. It would be good if this info can be available more prominent in the getting started or in the Post-install notes. ---

We are currently in the process of reworking the getting started / install section and will take your input into consideration.
