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/
