Some more info.

When I press "Select a cerificate (required)"


I see this

which certificated it is asking for and how to get one?
certificate is already in my ovpn file isn't it?

above config works perfectly well in CYDIA APP GUIZMOVPN and lot easier to setup.

The problem is that 1.0.0 doesn't support client profiles that don't have a client certificate. This has already been fixed in the upcoming 1.0.1 release where you can add this to your profile to disable client certificate usage:

Code: Select all

setenv CLIENT_CERT 0


This is necessary to resolve an ambiguity when the profile contains no client certificate or key, because otherwise the client app can't know whether an external certificate/key pair should be obtained from the Keychain, or whether the server actually doesn't require a client certificate/key. The option is given as a "setenv" to avoid breaking other OpenVPN clients that might not recognize it.

As a workaround before 1.0.1 is available, you can simply include a randomly generated certificate/key pair. The client will send it to the server, but the server will ignore it if it doesn't require a client certificate.

By adding some random key and certificate, config added successfully.
But I am not able to connect using the config, it gives connection time out.

I have tested same config on android and got same error but today evening play store has pushed update and same config worked without changes.

I think ios required update too so the same config work under ios as well.

Please suggest some tweak so this config works in IOS too.

I'm having a similar problem:

In my config, using certificates, when i import the profile in iPad OpenVPN Connect client (with inline certificate), the clietn doesn't import it, and same message is displayed "No certificates are present in the Keychain"

I read version 1.0.1 can correct this, but it's not publicly realeased, isn't it?

My profile file is (also tryed adding "setenv CLIENT_CERT 0" with no success):

Code: Select all

persist-tun
persist-key
cipher AES-128-CBC
tls-client
client
remote XXXXXXXXXXXXXX 443 tcp
auth-user-pass

# dont terminate service process on wrong password, ask again
auth-retry interact
# open management channel
management 127.0.0.1 166
# wait for management to explicitly start connection
management-hold
# query management channel for user/pass
management-query-passwords
# disconnect VPN when managment program connection is closed
management-signal
# forget password when management disconnects
management-forget-disconnect

Overall, installing and trying to use OpenVPN on my iPad has wasted a lot of my time. I cannot find anyplace in the forums about how to create and install random keys and certificates.

No need to creat one, just paste one I posted in your config.

I got OpenVPN to work on my iphone by just sending the ovpn file via email after replacing line "ca ca.crt" with content of the ca.crt. Here you go a copy of my openvpn.ovpn file which I slightly modified based on inputs I found in this forum:

Code: Select all

client
dev tun

remote  [your_wan_ip]  1194
resolv-retry infinite

Sections "ca" and "cert" contains the content of ca.crt file. The section "key" is just junk data.

It is important to note that on line "remote [your_wan_ip] 1194" it is needed to replace [your_wan_ip] by the current WAN IP of the openVPN server.

Unfortunately I cannot edit my previous post to give an update. Please follow these new instructions:

On the iPhone, go to Settings and scroll down until you see OpenVPN, get there and activate setting "Force AES-CBC ciphersuites"

Then edit your openvpn.ovpn file and change it as follows:

Code: Select all

client
dev tun
script-security 3
proto udp
remote  [your_wan_ip] 1194
resolv-retry infinite
nobind

<ca>
-----BEGIN CERTIFICATE-----
MIIDszCCAxygA....
....n1KLGtBBtPH9e
-----END CERTIFICATE-----
</ca>

auth-user-pass
cipher AES-256-CBC
tls-cipher TLS-SRP-SHA-RSA-WITH-3DES-EDE-CBC-SHA:TLS-DHE-RSA-WITH-AES-128-CBC-SHA:TLS-DHE-RSA-WITH-AES-256-CBC-SHA
comp-lzo
pull


where the section "ca" contains the content of ca.crt file.

It is important to note that on line "remote [your_wan_ip] 1194" it is needed to replace [your_wan_ip] with the current WAN IP of the openVPN server.
