[Openvpn-devel] [PATCH] Restrict options/configs for startup through interactive service

2016-02-19 Thread Selva Nair
Hi, The pacth is in the next email. This is not yet tested extensively, but has passed some quick tests. A simple approach of parsing the options string is used instead of passing structs: the latter will break the GUI everytime a new option is added to the white-list. Current white-list is jus

Hi, We just got an EV certificate token thingy, which certainly does not have SHA-1. The problem is that the token makes it impossible to safely automate the signing process. So basically we have to turn off automated signing in openvpn-build and just sign the files we absolutely have to. This

Hello, I am currently working on a project that requires SSL VPN to use session resumptions. I need to add the TLS Session Resumption functionality to OpenVPN. Any starters as in how I could achieve this? I know about the SSL_OP_NO_TICKET flag added to disable the resumption process. Will deletin

Thanks. I didn't knew about this. This will be helpful. I am specifically looking for enabling TLS session resumptions though. Resuming the session with session IDs stored in a cache at server side (the general process of an abbreviated handshake). On Feb 19, 2016 7:50 PM, "Arne Schwabe" wrote:

Thank you for such a quick reply. I agree that VPN sessions and SSL sessions are not necessarily the same. Let me be more specific with my question for a better discussion. In an active OpenVPN session, at regular intervals, a full SSL handshake takes place (because the SSL session expires). I ch
