问题 I have been looking around for a way to launch the VPN settings activity through my android app, but cannot find it.

问题 I am working with the basic Cisco VPN client (v.5 I believe). Is there anyway to determine programatically if a partciular profile (or any profile for that matter) is connected?

问题 As title says, trying to connect vpn via bash. The following script seemed closest to the answer I'm looking for: #!/bin/bash /opt/cisco/anyconnect/bin/vpn -s << EOF connect https://your.cisco.vpn.hostname/vpn_name here_goes_your_username here_goes_your_passwordy EOF When I run this the vpn starts but then exits without an error and without connecting.

I can connect to the VPN server in Windows 7 using Domain Credentials like \DOMAIN\user but I want to be able to connect to the SQL server with the Domain Credentials because I don't have the sa account . 回答1: Try creating a shortcut with: runas /noprofile /netonly /user:domain\username ssms.exe You may have to hard-code the path to ssms.exe. In a few locations it will look in SSMS like you are using
