Network connected drives

Many departments and staff use Network Attached Storage (NAS) to store departmental files for documentation and/or projects. To request access to a departmental shared drive, please have your department chair or secretary send a request on your behalf to it@liu.edu.

If you are requesting to have a new share drive created for yourself then simply make the request to the same email as above.

Cisco Anyconnect

Cisco Anyconnect is a Virtual Private Network (VPN) client that allows you to securely connect to the LIU administrative network from off campus. In order to get VPN access, you must fill out a VPN access request form, as well as have your laptop wiped and encrypted for work use.

Troubleshooting Q&A

Although your device my indicate that you are connected to LIUNET, you MUST log in or else the connection is not active. In the event the login page doesn’t present itself, open a browser and try to go to any website. If you are not logged in, the network will automatically redirect you to the login page.

Check to see if you can log into your email or MYLIU using a different device or on a computer using a wired connection. If you are unable to gain entry it is possible that your credentials may have expired and you need to have your password reset. 

Sometimes a device or computer can get confused about what network connection it is on. Close all web browsers and turn off your wifi. Wait 15 seconds then turn your wifi back on. Reconnect to LIUNET and login.

Check to make sure all wires are securely plugged in – You should hear a click when the cable is properly seated.

Restart the machine – A computer may be confused about it’s connection, a restart can clear things up.

Try a different wire – Sometimes wires get damaged and although not visible, may be broken on the inside.

Plug a different Device into the network port – Isolate whether it is an issue with the connection or the machine.

The University network provides inter-connectivity between all departmental and campus networks, and also provides connection between these networks and the Internet. This is accomplished by having a resilient high speed Gigabit Ethernet backbone that is supported by 6 Cisco® Catalyst® 6500 Series multi-layer modular switches. The backbone extends to all University buildings and provides access to and from Fast Ethernet segments. Users’ end nodes are connected at 10/100Mbs via a combination of Cisco Catalyst 6500, 4000 and 3500 access layer switches. A fiber optic Ethernet network interconnects the central computer configuration. We are currently multi-homed to the Internet by means of two Internet Service Providers (ISPs). The ISPs that we are using are Cogent and Cablevision Lightpath. They both provide us with a 100Mb link to the Internet. Our Internet-facing Cisco router includes a Cisco’s Firewall Services Module which provide advanced security services including firewalling capabilities.
