Don’t run "sudo" on CISL systems

August 16, 2019

Use of the sudo command on Cheyenne and other systems that CISL manages is restricted to authorized users and CISL staff members. The command fails and raises a security alert to the system administrators when unauthorized users try to run it – for example, when attempting to install software packages system-wide or to act on other users’ files.

CISL logs such failed attempts and contacts users to offer assistance. If you need help with tasks that you think require sudo privileges, or if you aren’t sure, it is best to contact or call 303-497-2400 before running sudo yourself.
