ANSWERED Eddie 2.11.7 on Windows 10 x64: Unrecognized directive or missing parameter: block-ipv6

[vpnadmin 3]

Hey there,

 

I'm using the latest experimental Eddie with a custom provider (own OpenVPN server). 

After connecting I get the message: Unrecognized directive or missing parameter: block-ipv6

 

Note: the connection is correctly established and I can surf the web with this tunnel at this time.

After clicking "OK" the message disappears and the connection is terminated. 

 

This is the relevant line at the logfile:

 

. 2016.11.28 13:59:17 - OpenVPN > PUSH: Received control message: 'PUSH_REPLY,explicit-exit-notify,topology subnet,route-delay 5 30,dhcp-pre-release,dhcp-renew,dhcp-release,route-metric 101,ping 12,ping-restart 50,comp-lzo yes,redirect-gateway def1,redirect-gateway bypass-dhcp,redirect-gateway autolocal,route-gateway 172.27.232.1,dhcp-option DNS 91.239.100.100,dhcp-option DNS 89.233.43.71,register-dns,block-ipv6,ifconfig 172.27.232.3 255.255.248.0'

I tried to remove the directive in the server config but this does not work. (It is an official OpenVPN access server and I'm not able to edit the push directives directly. Nontheless, since I can browse the web after connecting it seems like a bug to me. Anything I can do here?

 

Thanks!

Why exactly you cannot remove this directive? Upgrade to the latest OpenVPN AS as soon as you can anyway.

It does not change anything. I updated to latest OVPN/TAP driver now and it seems that this entry is added by Eddie. Look at the temporary config file that is generated upon connecting:

This entry can't be seen in the original config file. I don't know what's happening here ...

 

Edit: found the relevant code snippet in AirVPN.xml and removed it. Now it can't be seen anymore in the temporary ovpn-config. Nontheless the server seems to keep pushing the directive and the same message appears.

I think I should add: the same config file works pretty fine with the regular OpenVPN connect on the same system. So this is most likely an Eddie-related thing here.

Very interesting (using Eddie with custom OVPN, using Eddie with OpenVPN 2.4beta, nice!)

 

Eddie intercepts a message "Options error: Unrecognized option or missing parameter" that comes from OpenVPN, and reflects the message in the logs.

 

The bug in Eddie is the fact that Eddie may consider it a FATAL error and close the connection.

 

the same config file works pretty fine with the regular OpenVPN connect on the same system. So this is most likely an Eddie-related thing here.

 

Simply, OpenVPN connect hides this unrecognized option.

 

"block-ipv6" directive doesn't exist neither in OpenVPN 2.4 : https://community.openvpn.net/openvpn/wiki/Openvpn24ManPage

But your OpenVPN server pushes it.

Maybe an internal/testing directive, or directive that is accepted only on some platform (for example Android).

 

We will add an option "Ignore unrecognized directives" in the next Eddie version 2.11.8 (that will be released today or tomorrow). (Edited)

[Clodo 182]

OpenVPN unrecognized directives throw a log message "Unrecognized option or missing parameter" in any case.

OpenVPN normally continues if the directive comes from a "push", or stops if the directive comes from an .ovpn file.
Eddie stops in both cases. This is a bug. It will be fixed in the next release.

Great, appreciate your help!

 

Regarding the directive: found this on some OVPN dev list http://permalink.gmane.org/gmane.network.openvpn.devel/7808

Maybe it is used only in commercial environments (which I'm using here). 

 

Anyway, thank you, I'm looking pretty much forward to the next beta then! :-)
