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.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Leap 15.5 users, for example, can do this with the following command:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.5 snappy
Swap out openSUSE_Leap_15.5 for openSUSE_Leap_15.4 or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
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.
