--- title: Install Secure Tunnel Client on Ubuntu using the Snap Store | Snapcraft description: Get the latest version of Secure Tunnel Client for on Ubuntu - Encrypted TLS TCP port-forwarding & SOCKS5-over-TLS tunnel client & server url: https://snapcraft.io/install/secure-tunnel-client/ubuntu --- [Canonical Snapcraft](https://snapcraft.io/) # Install Secure Tunnel Client on **Ubuntu** # Secure Tunnel Client [Nguyen Van Thanh (thanhnv128)](https://snapcraft.io/publisher/thanhnv128 "View all snaps from Nguyen Van Thanh (thanhnv128)") * [Nguyen Van Thanh (thanhnv128)](https://snapcraft.io/publisher/thanhnv128 "View all snaps from Nguyen Van Thanh (thanhnv128)") * [Utilities](https://snapcraft.io/search?categories=utilities) [Install](https://snapcraft.io/install/secure-tunnel-client/ubuntu#install) #### Encrypted TLS TCP port-forwarding & SOCKS5-over-TLS tunnel client & server Secure Tunnel Client is a lightweight Linux alternative to SoftEther VPN Client workflows for user-space TLS-encrypted TCP port-forwarding, SOCKS5-over-TLS tunneling, and Linux network interface monitoring. Features (100% real sockets and kernel telemetry): * SQLite-backed TLS Tunnel Profiles supporting both Client Mode and Server Mode * TLS 1.2 / TLS 1.3 encryption using Python ssl.SSLContext with X.509 certificate generation (RSA-2048 PEM) or custom PEM certificate/key files * Optional pre-shared token authentication and SHA-256 peer certificate pinning * TCP Port-Forwarding over TLS and built-in RFC 1928 SOCKS5-over-TLS listener * Real-time TLS cipher negotiation inspector, peer SHA-256 fingerprint, and encrypted tunnel RTT ping probe * Multi-port forward rules manager, live stream monitor, CSV export, and live measured TX/RX throughput graph * System Network & Tunnel Interfaces Inspector reading /sys/class/net, /proc/net/dev, /proc/net/if\_inet6, ioctl IPv4 addresses, and /proc/net/route Honest scope & limitations: Operates strictly as a user-space TLS-encrypted TCP port-forwarder and SOCKS5-over-TLS proxy tunnel. It does NOT create a kernel Layer-2/Layer-3 virtual network adapter (TUN/TAP), does not modify system-wide routing tables, and does not tunnel raw UDP or ICMP packets.

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 If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), you don’t need to do anything. Snap is already installed and ready to go. For versions of Ubuntu between [14.04 LTS (Trusty Tahr)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), as well as Ubuntu flavours that don’t include *snap* by default, *snap* can be installed from the Ubuntu Software Centre by searching for *snapd*. Alternatively, snapd can be installed from the command line: ``` sudo apt update sudo apt install snapd ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install Secure Tunnel Client To install Secure Tunnel Client, simply use the following command: ``` sudo snap install secure-tunnel-client ``` ### 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?
