Blocked applications

Any applications not listed on this page can be assumed to be allowed.  Please note that these lists can be subject to change and may not be fully up to date at all times.  If you have a question about an application that appears to not be working and it's not listed on this page, please contact the UTC help desk to ask about it.

Government mandated

Includes: qq, tiktok, wechat

Why: The federal or state government has mandated that these be blocked


  • Wait until you are home
  • Use cellular networks
  • Use 3rd party VPN (see remote access section on this page)

Peer-to-peer file sharing

Includes: (but not limited to) BitTorrent, emule, kazaa, qBittorrent, uTorrent, etc

Why: These applications are largely used for sharing copyrighted media.


  • Google Drive (provided to all students)
  • OneDrive (provided to all faculty, staff, and students)


  • Don't share things illegally

Remote access applications

Includes: Anydesk, LogMeIn, TeamViewer, Wireguard, Zerotier

Why: These applications permit remote access into UTC's network through an unapproved method


  • If you want remote access to UTC's network, use the UTC VPN.
  • If you want remote access to an external system, use a traditional style VPN. (e.g. OpenVPN)
  • If you want to do screen sharing and/or remote control, use Zoom as the officially provided and supported application


  • All traditional style VPNs are not blocked, including personal and 3rd party.  Only ones that also permit connections back in are blocked.


Includes: Unauthenticated SMTP on port 25

Why: Port 25 is not authenticated and is widely misused by things like malware and spam hosts


  • Most mail providers support authenticated SMTP (port 465 or 587).  This is the recommended way to send email.
