For windows, they provides a client which includes a openvpn.exe that seems as a custom built or maybe a commercial version.

Of all the options, this one " --ext-magic-crypto" is not explained in the comunity version documentation of openvpn."C:\Program Files (x86)\FlyVPN\openvpn\openvpn.exe" --proto udp --mssfix 1320 --remote 187.157.45.17 53 --nobind --dev tap --auth-user-pass --pull --ca ca.crt --tls-client --service OPENVPN_EXIT_{05F607A4-6E2F-42e8-AFE0-7F56211E6B88} --remap-usr1 SIGTERM --verb 5 --redirect-gateway def1 --ext-magic-crypto --comp-lzo
Can someone confirm if this OpenVPN Accelerator is part of the commercial version of openvpn
I think it could be to add some external encryption or HMAC implementation or key.
If i manually run without it the log ends with this lines:
I am still waiting for their support response.us=997000 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
us=997000 TLS Error: TLS handshake failed
us=13000 Send P_VPN_COMMAND: 1
us=13000 Send P_VPN_COMMAND: 1
us=13000 TCP/UDP: Closing socket
us=13000 SIGTERM[soft,tls-error] received, process exiting
I want to connect to them with a linux client of openvpn. In their web site they claim linux support but no information is given on this.
If they are using some customized version, or don't provide info on the linux client, then i probably will try PPTP o L2TP/IPSEC.
As a last option i think i could use this advice to build a OpenVPN server in AWS : http://swimminginthought.com/amazons-fr ... n-server./
