Push additional information about the client to server. The additional information
consists of the following data:
Push additional information about the client to server.
The following data is always pushed to the server:
IV_VER=<version> -- the client OpenVPN version
IV_PLAT=[linux|solaris|openbsd|mac|netbsd|freebsd|win] -- the client OS platform
IV_LZO_STUB=1 -- if client was built with LZO stub capability
IV_LZ4=1 -- if the client supports LZ4 compressions.
IV_RGI6=1 -- if the client supports
.B \-\-redirect\-gateway
for ipv6
IV_PROTO=2 -- if the client supports peer-id floating mechansim
IV_NCP=2 -- negotiable ciphers, client supports
.B \-\-cipher
pushed by the server, a value of 2 or greater indicates client
supports AES-GCM-128 and AES-GCM-256.
IV_UI_VER=<gui_id> <version> -- the UI version of a UI if one is
running, for example "de.blinkt.openvpn 0.5.47" for the
Android app.
When
.B \-\-push\-peer\-info
is enabled the additional information consists of the following data:
IV_HWADDR=<mac address> -- the MAC address of clients default gateway
IV_LZO_STUB=1 -- if client was built with LZO stub capability
IV_SSL=<version string> -- the ssl version used by the client, e.g. "OpenSSL 1.0.2f 28 Jan 2016".
IV_PLAT_VER=x.y - the version of the operating system, e.g. 6.1 for Windows 7.
UV_<name>=<value> -- client environment variables whose names start with "UV_"
