在 Android 上连接到 IBM VPN
我觉得一定可以使用 L2TP/IPSec CRT VPN 连接到带有 Android 的 IBM VPN，但我不完全确定。 IBM 员工使用集成了 VPN 管理的 AT&T Global Network Connect Client。虽然这个客户端是专有的，但我认为专有部分是它尝试互联网连接的方式，而不是真正的 VPN 部分。
以下是全球网络客户端报告的 VPN 详细信息：
Service: Managed VPN - IPSec DualAccess (default)
VPN Server IP address: XXX.XXX.XXX.XXX
VPN Server type: AGN SIG
VPN Key Exchange Security: Diffie-Hellman Group 2
VPN Data Security: ESP,3DES,SHA1
VPN Data Compression: LZS
我可以在 VPN 连接期间看到客户端正在验证证书。我的猜测是，如果我可以在笔记本电脑上找到此证书，将其上传到我的 SD 卡，并在 Android 上注册该证书，我就可以成功地使用 L2TP/IPSec CRT VPN 设置连接。
知道在笔记本电脑上哪里可以找到客户端证书吗？
有接受者吗？
I feel like it must be possible to connect to the IBM VPN with Android using an L2TP/IPSec CRT VPN, but am not totally sure. IBMers use the AT&T Global Network Connect Client that has integrated VPN management. While this client is proprietary, I think the proprietary parts are the way it attempts internet connections, not really the VPN part.
Here are the VPN details reported by the Global Network Client:
Service: Managed VPN - IPSec DualAccess (default)
VPN Server IP address: XXX.XXX.XXX.XXX
VPN Server type: AGN SIG
VPN Key Exchange Security: Diffie-Hellman Group 2
VPN Data Security: ESP,3DES,SHA1
VPN Data Compression: LZS
I can see during VPN connection where the client is verifying a certificate. My guess is if I could find this certificate on the laptop, upload it to my SD card, and register the certificate on the Android, I could set up the connection successfully with a L2TP/IPSec CRT VPN.
Any idea where the client certificate could be found on the laptop?
Any takers?

AFAIK，在大多数 Android 智能手机上，您无法以用户身份执行此操作，因为无法访问您所需的设置。
http://code.google.com/ 对此进行了详细讨论p/android/issues/detail?id=3902
因为它需要更改 ROM，所以唯一的解决办法就是您是否愿意 root 手机。
据我目前所知，唯一的例外是摩托罗拉 Droid Pro，它内置了必要的 ROM 修改。有大量关于它的文章，因为摩托罗拉声称它是唯一支持 Cisco IPSec 的 Android - 例如 http://www.pcworld.com/businesscenter/article/207556/new_droid_pro_security_features_lead_the_way.html
AFAIK, on most Android smartphones, you can't do it as a user, because there aren't access to the settings that you need.
This has been discussed at length at http://code.google.com/p/android/issues/detail?id=3902
Because it needs a change in the ROM, the only way around it for you is if you're willing to root your phone.
The only exception to this that I'm currently aware of is the Motorola Droid Pro, which has the necessary ROM modifications baked-in. There are a ton of articles around about it as Motorola made a bit of noise about it being the only Android to include support for Cisco IPSec - e.g. http://www.pcworld.com/businesscenter/article/207556/new_droid_pro_security_features_lead_the_way.html
