I was looking for a way to disable the setting of «Trusted Servers» on my Cisco AnyConnect Secure Mobility Client Version (version 4.7.00136) specifically.

Through the graphical user interface is easy to change, but ¿where is stored that configuration?

The «three profile» settings

Connections

At first I went to /opt/cisco/anyconnect/profile/ANYCONNECT_Client_Profile.xml because there was stored the value of the server to connect under the <HostAddress> tag, but no clue for any «Untrusted Setting».

After changing the setting through the GUI the file /opt/cisco/anyconnect/.anyconnect_global was touched but nothing changed on it.

Finally I found that the setting was being stored in my user at /home/myuser/.anyconnectwith the tag <BlockUntrustedServers>

¿How I found it was that file?

First I’ve investigated which binaries had something to do with «Block», the binary in charge of it was vpn:

Then I executed the binary with the parameters to change the setting using a strace to see which files were called:

It tried to open several files but wrote in one that called my attention:

Cisco Anyconnect Block Connections To Untrusted Servers

After checking its content it was clear that the setting was stored there.

The real question is ¿why the client stores the information of the url you are connecting in one profile settings under /opt and then saving the other setting in your /home/user/ file?

That has not any sense, but well, at least I was able to change it.

I have 2 VPN and sometimes I should switch them very often. I decided to create .bat file which could connect to desired VPN with credentials set in this file.

So I create .bat file with following code:

Where 1.txt contains credentials of VPN #1 which has trusted cerficate.
here's what 1.txt contains:

Where 1 goes for GROUP with number 1.

Anyconnect Cannot Verify Server

The second VPN is untrusted and I have this prompt awaring me what VPN is untrusted. Download cognex usb devices driver. I used similar code for .bat file:

And following data in 2.txt:

Cisco Anyconnect Block Connections To Untrusted Servers

Cisco Anyconnect Block Connections To Untrusted Servers

('y' goes for accepting untrusted server)

But now it says 'Login failed' after entering password is prompted and then it appears in loop and never stops.

The question is: how should I modify my 2.txt file to make script connect to VPN #2?
