Nikos, I'm attempting to get the Cisco AnyConnect client to create tunnel to the server. For testing, I disabled user authentication (there is only one cert in this CA). My --debug log is below. I added a an fprintf into the do..while loop in tls_read(). It looks like the client is closing the stream. Before I go wandering down the wrong path, can you check my attached config to make sure I'm not missing anything simple? listening (TCP) on [0.0.0.0]:443... listening (UDP) on [0.0.0.0]:443... ocserv[4732]: [main] processed 1 CA certificate(s). ocserv[4735]: [X.X.X.116]:54332 accepted connection ocserv[4735]: [X.X.X.116]:54332 client certificate verification succeeded ocserv[4735]: [X.X.X.116]:54332 TLS handshake completed gnutls_record_recv returned 898 ocserv[4735]: [X.X.X.116]:54332 HTTP: User-Agent: AnyConnect AppleSSLVPN_Darwin_ARM (iPhone) 3.0.09115 ocserv[4735]: [X.X.X.116]:54332 HTTP: Host: lakedaemon.net ocserv[4735]: [X.X.X.116]:54332 HTTP: Accept: */* ocserv[4735]: [X.X.X.116]:54332 HTTP: Accept-Encoding: identity ocserv[4735]: [X.X.X.116]:54332 HTTP: X-Transcend-Version: 1 ocserv[4735]: [X.X.X.116]:54332 HTTP: X-Transcend-Version: 1 ocserv[4735]: [X.X.X.116]:54332 HTTP: X-AnyConnect-Identifier-ClientVersion: 3.0.09115 ocserv[4735]: [X.X.X.116]:54332 HTTP: X-AnyConnect-Identifier-Platform: apple-ios ocserv[4735]: [X.X.X.116]:54332 HTTP: X-AnyConnect-Identifier-PlatformVersion: 6.1.2 ocserv[4735]: [X.X.X.116]:54332 HTTP: X-AnyConnect-Identifier-DeviceType: iPhone4,1 ocserv[4735]: [X.X.X.116]:54332 HTTP: X-AnyConnect-Identifier-Device-UniqueID: YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY ocserv[4735]: [X.X.X.116]:54332 HTTP: X-Aggregate-Auth: 1 ocserv[4735]: [X.X.X.116]:54332 HTTP: Connection: close ocserv[4735]: [X.X.X.116]:54332 HTTP: Content-Length: 320 ocserv[4735]: [X.X.X.116]:54332 HTTP: Content-Type: application/x-www-form-urlencoded ocserv[4735]: [X.X.X.116]:54332 sending authentication request ocserv[4732]: [main] assigning tun device vpn0 ocserv[4732]: [X.X.X.116]:54332 user 'C=US,O=Home,CN=jason_iphone' of group '[unknown]' authenticated ocserv[4735]: [X.X.X.116]:54332 User 'C=US,O=Home,CN=jason_iphone' logged in gnutls_record_recv returned 0 ocserv[4735]: [X.X.X.116]:54332 error receiving client data (0) And, my sample.config: ### begin ############################################################ # User authentication method.
