history
Project history and usage
ocproxy is a user-level SOCKS and port-forwarding proxy designed for OpenConnect VPN sessions. Instead of sending all host traffic through a VPN interface, it lets users route only selected connections through forwarded ports or a SOCKS5 proxy.
Project history
The project changelog lists an initial release on 2012-11-20, version 1.50 on 2014-07-06, and version 1.60 on 2017-01-08. The authors file credits David Edmondson and Kevin Cernekee for ocproxy/vpnns work in 2012-2014 and Google Inc. for 2016 contributions, with lwIP credited separately.
Version 1.50 fixed stability issues seen under SOCKS browsing load, added a man page, moved the build to GNU autotools, updated lwIP, and added Ubuntu PPA packaging scripts. Version 1.60 added an experimental `vpnns` helper for Linux network namespaces and refined SOCKS binding behavior.
Adoption history
ocproxy is niche but broadly recognizable in VPN packaging: Homebrew, Debian/Ubuntu, Fedora, Nix, and related package sets carry it. Its presence in these package managers reflects a practical sysadmin need rather than a large application ecosystem: selective VPN routing without root-level host network changes.
How it is used
The README says ocproxy should be started by OpenConnect with `--script-tun`, commonly with `-D` for a SOCKS5 listener and `-L` for local-to-remote port forwarding. Users then point SSH, RDP, SOCKS-aware tools, browser proxy rules, tsocks, or Dante at the local proxy or forwarded ports.
The documentation also describes use cases such as routing different applications or browser profiles through different VPNs, connecting to multiple VPNs with overlapping address ranges, and working on multiuser systems or machines where root access is unavailable or undesirable.
Why package nerds care
ocproxy is a compact example of a network utility whose packaging value comes from composition: OpenConnect supplies the VPN transport, lwIP supplies a userland TCP/IP stack, and ocproxy exposes a Unix-friendly proxy/port-forwarding surface.
Timeline
- 2012-11-20: initial release.
- 2014-07-06: version 1.50 improved SOCKS stability, added a man page, adopted autotools, and refreshed lwIP.
- 2017-01-08: version 1.60 added experimental `vpnns` and local SOCKS bind-address support.
Related projects
- ocproxy is closely tied to OpenConnect, lwIP, SOCKS tooling such as tsocks and Dante, and the Linux network-namespace helper `vpnns` included in the same repository.
