The various parameters for setting up the port forwarding are configured using snap configuration parameters. Set the various values as follows (changing the values as needed): ``` snap set hintertuer local-port="443" snap set hintertuer local-host="localhost" snap set hintertuer remote-port="10443" snap set hintertuer remote-host="myhost.example.com" snap set hintertuer remote-addr="localhost" snap set hintertuer user="ubuntu" ``` This example configuration will result in port 443 (local-port) on the host localhost (local-host), as if it were accessed by the client host (where the snap is installed), being made available on port 10443 (remote-port) on myhost.example.com (remote-host), bound to the address localhost (remote-addr). In order to improve security, the remote host's key must be configured. You can obtain the key by using the `ssh-keyscan` utility, and configuring the snap with that key: ``` snap set hintertuer host-key="..." ``` Or combine it into one line: ``` snap set hintertuer \ host-key="$(ssh-keyscan $(snap get hintertuer remote-host))" ``` The snap will generate a new SSH key called "id\_ecdsa" and try to use that to connect to the remote host. This file is stored in the snap's common data path (normally /var/snap/hintertuer/common/). This file can be overwritten, or another file in that directory can be used by running the following command: ``` snap set hintertuer ssh-key="id_ecdsa" ``` After changing any of the configuration options, make sure to restart the snap: ``` snap restart hintertuer ``` The name "Hintertuer" comes from the German translation for "backdoor". ### Package name * hintertuer --- ### License * GPL-2.0+ --- ### Last updated * 9 October 2026 - latest/stable * 9 October 2026 - latest/candidate --- ### Contact * [isaac@is.having.coffee](mailto:isaac@is.having.coffee "mailto:isaac@is.having.coffee") --- ### Source code * [github.com/IsaacJT/hintertuer](https://github.com/IsaacJT/hintertuer "https://github.com/IsaacJT/hintertuer") --- ### Report a bug * [github.com/IsaacJT/hintertuer/issues](https://github.com/IsaacJT/hintertuer/issues "https://github.com/IsaacJT/hintertuer/issues") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/hintertuer/centos#report-snap-modal) --- ## Enable snaps on CentOS and install hintertuer Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [CentOS 7.6+](https://snapcraft.io/install/hintertuer/centos), and Red Hat Enterprise Linux 7.6+, from the [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The EPEL repository can be added to your system with the following command: ``` sudo yum install epel-release ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install hintertuer To install hintertuer, simply use the following command: ``` sudo snap install hintertuer ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
