Connect Your Linux Computer to the UTC VPN

Special Notes

All UTC faculty, staff, and students have access to the VPN.  By default only UTC’s publicly available services and the Internet are accessible.  If you require access to privileged services, you must request an account elevation.

The GlobalProtect client for Linux currently only supports CentOS, Redhat, and Ubuntu.  Derivatives are not officially supported and you will receive error messages.  If you use a different distribution, please contact the help desk to talk with our network group about it.

As of version 5.1.0 and higher there are two different versions; CLI or GUI.  You only have to install one of them.  As of 5.1.4, the CLI version is the better one and the following directions are for that client only.

Directions (First time)

  1. Open your preferred web browser to: https://vpn.utc.edu
  2. Download the appropriate software version (Linux)
  3. Once the download has completed, untar the archive (hint: move the tgz file into a subfolder first)
  4. Use your package manager (i.e. yum, dpkg, etc) to install the appropriate package for your distribution
  5. After installation, open a terminal
  6. Enter globalprotect connect --portal vpn.utc.edu
  7. When prompted for username and password, enter your UTCID and password

Directions (Subsequent connections)

  1. Open a terminal
  2. Enter globalprotect connect
  3. When prompted for username and password, enter your UTCID and password

Directions (Disconnect)

  1. Open a terminal
  2. Enter globalprotect disconnect

Troubleshooting

When trying to connect, if the GlobalProtect app gives an error stating “There is a problem with the security certificate, so the identity of vpn.utc.edu cannot be verified.” then most likely the operating system in use is not officially supported. The following steps can sometimes resolve the issue.

This is known to work with the following operating systems:

  • Linux Mint 18, 19

In a terminal window, enter the following commands:

SEARCH=Ubuntu
REPLACE=`lsb_release -ds | head -c${#SEARCH}`
TARGET=/opt/paloaltonetworks/globalprotect/PanGPS
sudo sed -i "s/$SEARCH/$REPLACE/g" $TARGET
sudo systemctl restart gpd.service
