Linux, Mac OS X, and Linux. This flag (which is pushable
from server) blocks client access to local LAN while VPN
session is active.
Added standalone --show-gateway option to show info about
default gateway.
Extensively refactored get_default_gateway function in
route.c to ease implementation of block-local.
Removed "Experimental" disclaimer from redirect-gateway
man page.
Version 2.1.3y.

This includes the new "static-challenge" directive.
See management/management-notes.txt for details on both
static and dynamic challenge/response protocols.
All client-side challenge/response code is #ifdefed on
ENABLE_CLIENT_CR and can be removed from the build
by commenting out the definition of ENABLE_CLIENT_CR
in syshead.h.

Don't call SSL_CTX_set_client_CA_list or SSL_CTX_set_client_CA_list
if not running in server mode (these functions are only useful for
TLS/SSL servers).
Modified openvpn_snprintf to return false on overflow, and true
otherwise.
When AUTH_FAILED,... is received, log the full string.

command on failure once every second for up to 15 seconds. This
is necessary to work around an issue observed on OSX 10.5 where
the ipconfig command sometimes fails if executed immediately after
the tun device open.

Then an error like this for every incoming connection that should be

Version 2.1.3s

UDP sessions when the client daemon was running in UDP/TCP adaptive
mode, and transitioned from TCP to UDP.
The bug would cause a single dropped packet in UDP mode to trigger a
barrage of packet replay errors followed by a disconnect and
reconnect.
Version 2.1.3r
git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@7125 e7ae566f-a301-0410-adde-c780ea21d3b5
pushed by server, and that is used to offer a temporary session
token to clients that can be used in place of a password on
subsequent credential challenges.
This accomplishes the security benefit of preventing caching
of the real password while offering most of the advantages
of password caching, i.e. not forcing the user to re-enter
credentials for every TLS renegotiation or network hiccup.
auth-token does two things:
1. if password caching is enabled, the token replaces the
previous password, and
2. if the management interface is active, the token is output
to it:
>PASSWORD:Auth-Token:<token>
Also made a minor change to HALT/RESTART processing when password
caching is enabled. When client receives a HALT or RESTART message,
and if the message text contains a flags block (i.e. [FFF]:message),
if flag 'P' (preserve auth) is present in flags, don't purge the Auth
password. Otherwise do purge the Auth password.
Version 2.1.3o
git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@7088 e7ae566f-a301-0410-adde-c780ea21d3b5
to accept an optional message string. The message string format is:
RESTART|HALT,<human-readable-message>
RESTART will tell the client to restart (i.e. SIGUSR1).
HALT will tell the client to exit (i.e. SIGTERM).
On the client, human-readable-message will be communicated via
management interface:
>NOTIFY,<severity>,<type>,<human-readable-message>"
Version 2.1.3m

a server if it sent multiple push requests due to the server being
slow to respond. This could cause the client to process pushed
options twice, leading to duplicate pushed routes, among other issues.
The fix, implemented server-side, is to reply only once to a push
request even if multiple requests are received.
