GlobalProtect-openconnect VS openconnect

In order to reach a client's domain for a project, my team needs to use a VPN and the instructions were pretty clear regarding which tool to use - GlobalProtect VPN - so I've installed https://github.com/yuezk/GlobalProtect-openconnect and was able to connect successfully.

Use this one instead https://github.com/yuezk/GlobalProtect-openconnect

Sometimes you may want to use some software in your project, but the maintainer(s) may have some functional affiliation(s) that makes it difficult to use without significant security assessment effort.

Example here: GlobalProtect is VPN software from Palo Alto Networks, but the maintainer of this open source client is based in China. He may be a fine, upstanding person, the code may be pristine, but there's systemic risk that needs to be bought down.

What are your tools of choice to assess something like this?

Ooh yes I recently went through this. This is the one that finally worked: https://github.com/yuezk/GlobalProtect-openconnect

I've seen this on Linux too, specifically with this VPN application https://github.com/yuezk/GlobalProtect-openconnect

Closing it via the "x" will minimize to tray and hide (which is the behavior I want, but an example nonetheless)

I work for a Uni running eduroam. Mine isn't hostile to Linux, but it is definitely a second class citizen. I run Linux where I can. I don't know where you are, but openconnect can probably work for you. Specifically, I use https://github.com/yuezk/GlobalProtect-openconnect/ on top of openconnect for SAML auth. Might be worth the try for you.

I'm not familiar with the service and software can only be downloaded and installed via the customer portal. Would something like GlobalProtect-openconnect or gp-saml-gui suffice?

Solution to the GlobalProtect problem is to install the non-official client https://github.com/yuezk/GlobalProtect-openconnect and follow the fix in issue #142 on the github repo.

A lot of software (including https://gitlab.com/openconnect/openconnect of which I'm a maintainer) uses libxml2, which in turn transitively links to libzma, using it to load and store compressed XML.

I'm not *too* worried about OpenConnect given that we use `libxml2` only to read and parse uncompressed XML…

But I am wondering if there has been any statement from libxml2 devs (they're under the GNOME umbrella) about potential risks to libxml2 and its users.

From the article:

> Ubiquitous presence of HTTPS allows you to pass your data through very restrictive middle boxes!

This is, in fact, why all — or nearly all — proprietary VPN protocols (so-called "SSL VPNs") implement a mode that initiates a tunnel via HTTPS, at least as a fallback if not as the primary mode of operation: precisely in order to have a mode of operation that works with almost any connection to the global Internet.

I'm one of the main developers of https://gitlab.com/openconnect/openconnect, which implements many such protocols, and wrote https://github.com/dlenski/what-vpn, which sniffs or identifies even more flavors of TLS-based VPN servers.

Found the solution: It's as simple, as changing the user agent with --useragent=AnyConnect. This is ridiculous. https://gitlab.com/openconnect/openconnect/-/issues/544

Source: I am one of the lead developers of OpenConnect, a popular open-source client for many corporate VPNs, and have done all of the above.

Be careful you're not using an illicit fork. https://gitlab.com/openconnect/openconnect

I personally have an openconnect server, and I patched their client to let me specify the SNI, (it's set to the server's hostname by default (https://gitlab.com/openconnect/openconnect/-/blob/master/gnutls.c#L2366), but it's optional in the anyconnect protocol spec)

Thank you, trying openconnect for multiple hours, but cannot auth, created issue about that https://gitlab.com/openconnect/openconnect/-/issues/446

If this is for anything other than AnyConnect I feel like you're better off with a t4g.nano running OpenVPN. If it's AnyConnect, you can run OpenConnect.

I had similar issue with Fortinet VPN. Try using something like https://gitlab.com/openconnect/openconnect. Run this from terminal to connect to VPN when needed. If this doesn't work search for global protect open source and there are other options.
