If you have been using Cisco AnyConnect VPN client in Mac for a while probably you have the impression that is not the best tool (and you are not alone). OpenConnect is a command-line client for. I'm using OpenConnect myself and also with a couple of customers to build VPNs to the ASA. All without any problems. When deciding between OpenConnect and AnyConnect, keep in mind that you still need AnyConnect licenses even if you use a third-party client to download an AnyConnect-image to place it on the ASA. OpenConnect OpenConnect is a client for Cisco's AnyConnect SSL VPN and Pulse Secure's Pulse Connect Secure.

OpenConnect is a client for Cisco's AnyConnect SSL VPN and Pulse Secure's Pulse Connect Secure.

Installation

Install the openconnect package.

Usage

See openconnect(8). Simply run openconnect as root and enter your username and password when prompted:

More advanced invocation with username and password. Input the password after running the command.

Often VPN providers are offering different authentication groups for different access configurations like for example for a full tunnel or split tunnel connection. To show the different offered auth-groups and to get more information about the connection to the server in general use:

Sometimes, connecting to a Cisco VPN, the CSD (Cisco Secure Desktop) mechanism is required (see: https://www.infradead.org/openconnect/csd.html). In that case using the '--csd-wrapper' parameter can help, the wrappers are stored under '/usr/lib/openconnect/'.

Juniper Pulse Client

In order to connect to a Pulse Connect Secure server you need to know the SHA-1 of its certificate.

Split routing

Split routing can be achieved using vpn-slice-git^AUR in place of vpnc-script, so that you can selectively access hosts over the VPN but otherwise remain on your own LAN. Example:

Integration

NetworkManager

Install the networkmanager-openconnect package, then restartNetworkManager.service.

Configure and connect with nm-applet (NetworkManager's icon tray utility from network-manager-applet) or similar utility.

See NetworkManager for details.

netctl

A simple tuntapnetctl.profile(5) can be used to integrate OpenConnect in the normal Netctl workflow. For example:

This allows execution like:

Note that this relies on LOCAL_USERNAME having a gpg-agent running, with the passphrase for the PGP key already cached.

If pass’ interactive query is wanted, use the following line for PASSWORD_CMD:

Adjust the DISPLAY variable as necessary.

OpenConnect is a cross-platform multi-protocol SSL VPN client which supports a number of VPN protocols:

• Cisco AnyConnect (--protocol=anyconnect)
• Juniper SSL VPN (--protocol=nc)
• Pulse Connect Secure (--protocol=pulse
• Palo Alto Networks GlobalProtect SSL VPN (--protocol=gp)
• F5 Big-IP SSL VPN (--protocol=f5)
• Fortinet Fortigate SSL VPN (--protocol=fortinet)

OpenConnect is not officially supported by, or associated in any waywith Cisco Systems, Juniper Networks, Pulse Secure, Palo Alto Networks, F5,or Fortinet, or any of the companies whose protocols we may support in the future.It just happens to interoperate with their equipment. Trademarks belong totheir owners in a rather tautological and obvious fashion.

An openconnect VPN server (ocserv), which implementsan improved version of the Cisco AnyConnect protocol, has also beenwritten.

OpenConnect is released under the GNU Lesser Public License, version 2.1.

Motivation

Development of OpenConnect was started after a trial of the Cisco AnyConnectclient under Linux found it to have many deficiencies:

• Inability to use SSL certificates from a TPM or PKCS#11 smartcard, or even use a passphrase.
• Lack of support for Linux platforms other than i386.
• Lack of integration with NetworkManager on the Linux desktop.
• Lack of proper (RPM/DEB) packaging for Linux distributions.
• 'Stealth' use of libraries with dlopen(), even using the development-only symlinks such as libz.so — making it hard to properly discover the dependencies which proper packaging would have expressed
• Tempfile races allowing unprivileged users to trick it into overwriting arbitrary files, as root.
• Unable to run as an unprivileged user, which would have reduced the severity of the above bug.
• Inability to audit the source code for further such 'Security 101' bugs.

Naturally, OpenConnect addresses all of the above issues, and more.

New protocols

Adding new protocols to OpenConnect is relatively simple, andadditional protocols have been added over the years since usingOpenConnect allows a developer to concentrate on the protocol itselfand most of the boring details about platform-specific tunnel managementand IP configuration, and handling of client SSL certificates, are alreadyresolved.

Openconnect Vs Anyconnect

If you have a protocol which you think it makes sense to support inOpenConnect, especially if you are able to help with interoperabilitytesting, please file an issuein GitLab.

Consistent multi-protocol support

Wherever possible, OpenConnect presents a uniform API and command-lineinterface to each of these VPNs. For example,openconnect --force-dpd=10will attempt dead peer detection every 10 seconds on every VPN thatsupports it, even though the actual mechanism used may be protocol-specific.Protocol-specific features and deficiencies are described on theindividual protocol pages.
