Bastionhost:FAQ about SFTP file transfer

Last Updated:Mar 31, 2026

Common questions and answers about SFTP file transfer in Bastionhost.

Why can't I access the file directory?

Check the following in order:

  1. Host account password and permissions — The O&M engineer must have a password configured for the host account and the required permissions on the host account. If no password is configured for the host account and the O&M engineer does not have the permissions on the host account, access to the file directory is blocked.

  2. Network connectivity — Confirm that the bastion host can reach the server. See Diagnose network issues.

  3. SFTP Channel setting — Verify that SFTP Channel is enabled in the control policy. See Manage control policies.

  4. Server-side SFTP access — Check whether SFTP access is disabled on the server itself.

If the issue persists after the above checks, the client may have cached a stale file directory. Click ... to return to the bastion host list, then refresh the list.

What do I do if the file directory is corrupted and unreadable after logging on to an SFTP client?

Double-click !now_gb18030.next_utf-8 in the client, then refresh the page to switch the Bastionhost encoding to UTF-8.

UTF-8
Note

!now_gb18030.next_utf-8 indicates that the default encoding standard of the current bastion host is GB 18030. After you double-click !now_gb18030.next_utf-8, the encoding standard is changed to UTF-8.

What methods can I use to upload and download files on a bastion host?

O&M typeMethods
SSH-based O&MCommands such as lrzsz and scp; SFTP-based tools (see O&M overview)
Remote Desktop Protocol (RDP)-based O&MDisk mapping; clipboard (copy with Ctrl+C, paste with Ctrl+V)

What do I do if no file list is displayed or I can't upload files during web-based O&M?

  1. Contact the administrator to verify that SFTP Channel is enabled in the control policy.

  2. Check whether the administrator has granted you directory permissions for the host account.
