Updates to Sandbox Reservation Internet Access Policy

Due to changes in our networking policies, we are updating the internet access policy within our sandbox reservation instances.
Hosts will no longer have internet access outbound.
This should not affect the overall functionality or access to the resources within the sandbox instances, connecting via VPN.

Keep Innovating!

Unable to VPN to PCCE lab sandbox through Anyconnect Client on Linux


I am testing Cisco's Outbound API's through my web application interface  on a Linux server(CentOS 6.9) machine.

Followed the below instructions to setup the anyconnect client and connect vpn :

 Copy over the installer(anyconnect-linux64-4.6.00362-predeploy-k9.tar.gz) to the user's home directory (/home/<user>)

 $ tar zxvf anyconnect-*.tar.gz

 $ cd anyconnect-*/vpn

 $ sudo ./

 Accept the terms and let the installation finish.

 $ /opt/cisco/anyconnect/bin/vpn -s connect <devnet sandox lab address>

 Prompts for username and password, provide the username and password.

Note: I do not have a GUI interface installation, I setup the anyconnect client through terminal. Also, I have the anyconnect tar.gz installer downloaded on my local windows machine downloads directory, I transfer the installer to the linux server machine through a ftp client(filezilla/winscp).

The above instructions I have referred from

The installation guide was not clear very detailed for Linux, and did not include the linux installer link as well.

My question is, have I missed any step above? SInce I get an error when I try to vpn into the PCCE lab, BElow is the complete connection trace -

$ /opt/cisco/anyconnect/bin/vpn -s connect
