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 is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
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.
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.
