File manager ​

How can I enable or disable the file manager ​

In a new install, the file manager will be enabled by default.

To enable or update the file manager, please run the following command:

v-add-sys-filemanager

To disable the file manager, please run the following command:

v-delete-sys-filemanager

File manager gives “Unknown Error” message ​

This seems to occur specifically when the line Subsystem sftp /usr/lib/openssh/sftp-server is removed or changed in /etc/ssh/sshd_config in such a way that the install script cannot update it to Subsystem sftp internal-sftp.

Short answer: add Subsystem sftp internal-sftp to /etc/ssh/sshd_config.

Long answer: Refer to the install script ./install/hst-install-{distro}.sh for all the changes made to /etc/ssh/sshd_config. For Debian, the changes can be summarised as follows:

# HestiaCP Changes to the default /etc/ssh/sshd_config in Debian 10 Buster

# Forced default yes
PasswordAuthentication yes

# Changed from default 2m to 1m
LoginGraceTime 1m

# Changed from default /usr/lib/openssh/sftp-server to internal-sftp
Subsystem sftp internal-sftp

# Changed from default yes
DebianBanner no

Changing all of the other parameters to their defaults and also changing to PasswordAuthentication no did not reproduce the error, thus it would seem to be isolated to the Subsystem sftp internal-sftp parameter.

For more information regarding debugging, inspect the Hestia Nginx log:

tail -f -s0.1 /var/log/hestia/nginx-error.log

I changed SSH port and I cannot use the file manager anymore ​

The SSH port is loaded in a PHP session. Logging out and logging back in will reset the session, fixing the issue.
