2. Links in “At a glance” sidebar vanish when current page would be the destination of link.
- Update IPv6 AS branch to use Python 2.7.
- Updated most pyovpn dependencies other than Twisted/Nevow — contents of current bundle:
- Build Python with readline support.
- Changed pyovpn version number to 2.0.
- Changed all scripts that reference python version number to use 2.7.
- Fix to generation of iptables rules for DNS traffic:
Because generated iptables rules trap DNS requests early in ASx_IN_PRE chain, if initial call to dns_server_subnets did not reduce the rules to empty, we must instead use the whole list of non-reduced rules, i.e. we cannot reduce them further based on access granted to private subnets or the public internet.
- Added comment in LinuxIPv4Forward to extend to IPv6 so that /proc/sys/net/ipv6/conf/all/forwarding is also set.
- Added CC_CMDS env var for debugging. CC_CMDS is a comma-delimited list of OpenVPN directives (such as iroute) to be appended to client-config list.

- Added post_auth script pasfp.py that shows connecting user, serial number, CN, and SHA1 fingerprint of leaf cert.
- Fixed some instances where transport.write (in Twisted) might be called with a unicode string, causing a Twisted exception. This was likely causing an issue with failover rsync where the ssh password was being passed as unicode to transport.write.
- Minor text updates to Admin UI. Due to IPv6 address notation, ranges should now be delimited by ‘;’ instead of ‘:’.
- Because of tradeoff between Beast mitigation with RC4 and RC4′s own weaknesses, turn off Beast mitigation by default, and change some of the related text in the Admin UI. In particular, Beast flag now defaults to false and is keyed by cs.beast_workaround2
- Added support for OpenVPN tls-version-min directive.
- Removed some debugging and redundant code.
- Added connect_timeout and server_poll_timeout parameters to Connect and VPNConnect methods (and capicli and ovpncli tools).
connect_timeout (optional int|str) : set connection timeout (seconds)
server_poll_timeout (optional int|str) : set server-poll-timeout OpenVPN
parameter (seconds) — the number of seconds to try each remote entry before moving on to the next
- The client backend as.conf can now specify a list of prepend and append config file directives to be applied before and after the config file.
- For example:
prepend_config.3=route 0.0.0.0 0.0.0.0
- Minor change in clisite to use new method IP.is_lo() to test whether address is a loopback address.
- Fixed issue where exceptions in AuthRPCServer._render_finalize were causing server-side stack traces to be sent to client.
- Minor rewording of BEAST option in Admin UI for clarity.
- If vpn.server.routing.snat_source list is non-empty, use it to generate SNAT interface list rather than enum_interfaces
