This article is for account-holders who have been given access to a Celigo-hosted SFTP file server. It contains everything you need to connect: the host, port, sign-in format, and how to verify the server's identity. You don't need a Celigo account — any standard SFTP client works, including OpenSSH, WinSCP, and FileZilla.
Connection details
Your business contact at the company hosting the server provides your username, your password, and the server's identifier. Keep this article with those details; together they are your complete connection instructions.
- Host — Your contact will provide you with a regional endpoint.
- Port — 22 (SFTP over SSH).
-
Username —
<username>@<identifier>. Enter the full string, including the@and the identifier, as your SFTP username. - Password — Provided by your contact. Password authentication is the only supported method; SSH keys are not currently accepted.
- Protocol — SFTP only. Plain FTP, FTPS, SCP, shell access, and port forwarding are not available.
If your network restricts outbound connections, add the server's IP addresses to your allow list.
Verify the server's host key
The first time you connect, your SFTP client shows the server's host key fingerprint and asks you to confirm it. The host keys are long-lived and don't change when the server is updated; if your client ever warns that the host key has changed unexpectedly, stop and confirm with your contact before reconnecting.
What you can do once connected
You are signed in to your own folder and can't see anyone else's. Inside your folder you can list, download, upload, create folders, rename, overwrite, and delete files.
Behavior worth knowing before you script transfers:
- Interrupted uploads restart from the beginning — The server doesn't support resuming a transfer from an offset. If a transfer is interrupted, send the whole file again. A partial upload is never left visible.
- Uploading to an existing file name replaces the file — Standard temp-name-then-rename upload patterns used by clients such as WinSCP work without configuration.
- Deleting a folder deletes its contents — Directory delete removes the folder and everything inside it, unlike servers that refuse to delete a non-empty directory.
- Maximum file size is 10 GB.
If you can't connect
Check that you entered the full username including @<identifier> provided by your contact, the right regional host, and port 22. Repeated failed sign-in attempts are throttled and can lock you out temporarily — wait before retrying. If you still can't connect, contact the company that gave you access; they can confirm your account is enabled and reset your password. See also Troubleshoot file server connections.
