Tcp recv eof openvpn android

Good afternoon. At me the following problem — openvpn does not work on devices with operating system IOS. In doing so, everything works on other operating systems including (MacOS). In this case, this situation is observed only if the certificates were generated in Mikrotik. If you import keys created into linux into it, everything works fine. First he gave such a mistake.

2017-06-25 01:43:04 EVENT: CORE_ERROR PolarSSL: error parsing config private key : PKCS5 — Requested encryption or digest alg not available [ERR]

How I figured this out was because the microphone encrypts the private key with a format that does not support iOS.

[root@ip-172-31-14-92 centos]# openssl asn1parse -in 1_cert_export_test-client-ovpn-12.key
0:d=0 hl=4 l=1311 cons: SEQUENCE
4:d=1 hl=2 l= 73 cons: SEQUENCE
6:d=2 hl=2 l= 9 prim: OBJECT BES2
17:d=2 hl=2 l= 60 cons: SEQUENCE
19:d=3 hl=2 l= 27 cons: SEQUENCE
21:d=4 hl=2 l= 9 prim: OBJECT BKDF2
32:d=4 hl=2 l= 14 cons: SEQUENCE
34:d=5 hl=2 l= 8 prim: OCTET STRING [HEX DUMP]:249CA7FCEC409541

48:d=3 hl=2 l= 29 cons: SEQUENCE

61:d=4 hl=2 l= 16 prim: OCTET STRING [HEX DUMP]:0A3C812B3F915210ADB830EC58C43845

On Linux such a conclusion.

[root@ip-172-31-14-92 centos]# openssl asn1parse -in client_07.key
0:d=0 hl=4 l=1294 cons: SEQUENCE
4:d=1 hl=2 l= 64 cons: SEQUENCE
6:d=2 hl=2 l= 9 prim: OBJECT BES2
17:d=2 hl=2 l= 51 cons: SEQUENCE
19:d=3 hl=2 l= 27 cons: SEQUENCE

48:d=3 hl=2 l= 20 cons: SEQUENCE
50:d=4 hl=2 l= 8 prim: OBJECT :des-ede3-cbc

After my manipulations, the algorithms coincided. But there was another mistake.
2017-06-25 23:01:56 Client exception in transport_recv_excode: PolarSSL: SSL read error : SSL — Processing of the Certificate handshake message failed

I ask to help with the decision of the given problem.

My PacketTunnelProvider is like this.

guard
let fileContent = providerConfiguration[ProviderConfigurationKey.fileContent] as? Data,
let caRef = providerConfiguration[ProviderConfigurationKey.caRef] as? Data,
let userCertificateRef = providerConfiguration[ProviderConfigurationKey.userCertificateRef] as? Data,

let userKey = String(data: userKeyRef, encoding: .utf8)?.replacingOccurrences(of: «\n», with: «\n»)

// Create representation of the OpenVPN configuration. Other properties such as connection timeout or

let vpnConfiguration = OpenVPNConfiguration().then <

// Apply OpenVPN configuration
let properties: OpenVPNProperties
do <
properties = try vpnAdapter.apply(configuration: vpnConfiguration)

completionHandler(error)
return

Then I go this error. Please let me know why this error happened.

[Resolved] NETWORK_EOF_ERROR (transport error)

Post by hey_aj » Sat Aug 26, 2017 11:25 am

Have been using OpenVPN on 3 different iOS devices for weeks without issues. Yesterday, all 3 encountered the same issue- my iPad and iPhone here on business travel in Australia, my wife’s iPhone back home in the US. Doesn’t matter if on cell data or wifi. Key problem seems to be a transport error per the log below. Client status toggles between «waiting for server» and «transport pause» before timing out. Had wife reboot our asus router but did not resolve. Grateful for any assistance.

Sure, two follow-up questions:
1) I assume you are referring to the log on my router, in which case I will need to check when I return home as I am currently remote
2) Any suggestion as to what I am looking for or what the issue is? Or, just generic guidance to check the log?

Re: NETWORK_EOF_ERROR (transport error)

You need to verify that a connection attempt was made and what went wrong.

Connection Timeout: NETWORK_EOF_ERROR

Post by christiansam » Sat Feb 02, 2013 10:17 am

I have problems connecting with openvpn connect (ios) to my openvpn server. Before any crypto-stuff can get handled out, it breaks up with the following message:
—
logfile:
EVENT: CONNECTIONG
Tunnel Options: .
Peer Info: .
.
TCP recv EOF
Transport Error: Transport error on ‘ ‘: NETWORK _EOF_ERROR
Client terminated, restarting in 2.
EVENT: RECONNECTING
—-
Authentifcation mode is set to TLS with KEY CERT and CA generated by the easy-rsa utility. Except for changing auth-mode to something else I I tried (nearly) every possible mix of client-configration setting, without any success. My client-conf is based on sample-file, provided in windows openvpn package and works well with linux, windows and android openvpn clients.

Can’t tell you exactly which version of the openvpn server I use, it is included in an alternative firmware for Linksys’ WRT54G/GL routers, please see: http://tomatovpn.keithmoyer.com/

Best regards,
christian

Exactly thesame problem here!
Having a look on the server side it seems the connection never reach the server!

Dns resolution is fine (I see it in logs) but Connection Timeout: NETWORK_EOF_ERROR suddenly appears.

Are we missing something?

The same configuration works fine on Openvpn Connect on android.

I made a reset to my primary router and
now the ddwrt have the same problem.
I don’t know why, I didn’t touch the ddwrt
configs at all. But I’m facing this problem.

When I use the internal connection (192.168.x.x)
I can connect to the server , but when I use
The Internet with my external ip, it doesn’t work.
I have all configured: noip; port forward on my
primary router. All worked fine before the router reset.

You fix the error just by adding the keysize
text on the server config, or you made
something else?
Did you creat other CRT or key file or something Else?

Re: Connection Timeout: NETWORK_EOF_ERROR

Post by boostpt » Mon Dec 09, 2013 9:24 pm

I’ve figured it out.

In my case it has nothing to do with keysize
My primary router was not properly configured.
It has several options for port forwarding.
And it wasn’t correctly configured.
Work like a charm now.

I have exactly the same log problem when I try to conect from my iPad (openvpn client) to my router (openvpn server).
