VPNs
I have a love/hate relationship with proprietary corporate VPNs. I spend way too much time wrangling them into some semblance of non-intrusive good behavior. OpenConnect helps. A lot.
I'm extremely indebted to the brilliant design of sshuttle. See sshuttle/sshuttle#777 ("Very few software programs are works of sublime, complex genius").
- OpenConnect ...
- I developed support for PAN GlobalProtect VPNs in this now-obsolete fork before they were integrated into upstream OpenConnect for the v8.00 release
- I'm now one of the main developers of OpenConnect and have contributed extensively to the OpenConnect client, including to the implementation of the PPP-based protocols Fortinet and F5, improvements in automated testing with mock servers, bugfixes, documentation, figuring out lots of corner cases, and more.
- I gave a talk about How VPNs Work to Data PDX in September 2020.
- OpenConnect for Android extended to include multiprotocol support (fork)
- Various contributions to NetworkManager-openconnect plugin (multiprotocol support, etc.)
- vpnc-script replacement for easy split-tunnel VPN configuration
- Identify SSL VPN servers en masse
Two-factor authentication
- Provision and use Symantec VIP Access tokens (fork)
- Provision RSA SecurID tokens via CT-KIP web service
- Interactively authenticate to GlobalProtect VPNs that require SAML
