ssh tunnel with built in ssh server. It can be run stand alone as ssh-tunnel and bind on local ssh server. Or it can be used as boilerplate to be added into own snap to enable remote application debugging without reliance on system ssh server. At which point ssh session runs confined in host snap context.
At install ssh key is generated and stored to configurations:
$ snap get ondra-snap-ssh-debug ssh-tunnel.local.ssh-pub-key
add this to your remove server to allow auto connection.
By default ssh tunnel and ssh server are disabled:
To configure ssh tunnel, use following configuration (with own values):
$ snap set ondra-snap-ssh-debug ssh-tunnel='{ "remote": {"target": "162.162.11.1", "forwarding-port": "2020", "remote.ssh-port": "22", "user": "ubuntu" }, "local": { "address": "localhost"}}'
To use built in ssh server, use following example:
$ snap set ondra-snap-ssh-debug ssh-tunnel.local.port=2040
$ snap set ondra-snap-ssh-debug ssh-server='{ "enabled": "true", "authorized-keys" : "ssh-rsa AAAA<MY SSH public key>== ondrej.kubik"}'
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, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
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.
To install ondra-snap-ssh-debug, simply use the following command:
sudo snap install ondra-snap-ssh-debug
Browse and find snaps from the convenience of your desktop using the snap store snap.
