Tips and Tricks at UW-Madison

SSH HACK

SSH-ing into UW-Madison CS workstations managed by the CSL is painful, mostly due to the way we enforce MFA: https://csl.cs.wisc.edu/docs/csl/linux-mfa/

“Note: Due to the authentication requirements of the AFS flle system, you can not use SSH Public Key authentication.”

Skip entering passwords and phone-2FA by reusing sessions: add this to your ~/.ssh/config

    ControlMaster auto
    ControlPersist yes
    ControlPath ~/.ssh/persist_connections/%r@%h:%p

Creating UW-Madison Google Groups

Forget about Microsoft 365 groups, mass-manage Google stuff access permissions with Google Groups! https://it.wisc.edu/services/google-groups/

Printer setup

UW CDIS uses papercut, here’s a way to set it up for your mac without using the web portal or the device driver.

Printers

Native AirPrint queues via PaperCut Mobility Print on print.cai.wisc.edu * alias: print.cdis.wisc.edu, papercut-win.cs.wisc.edu

Mac printer Device URI
CAI_BW_Simplex (default Gray) ipps://print.cai.wisc.edu:9164/printers/B%26W%20simplex%20queue
CAI_Color_Simplex ipps://print.cai.wisc.edu:9164/printers/Color%20simplex%20queue

*⌘P jobs show under Jobs Pending Release (not the Web Print page)

The credential is just netid/password
