DUO_PASSCODE environmental variable can be used to configure the method duo will use for validation:
push (Duo mobile app),
call (phone call) or
sms (SMS text method).
This can be set on the remote side (for example, in
# bashrc example export DUO_PASSCODE=push `` ```csh # cshrc example setenv DUO_PASSCODE push
Alternatively, this can be set locally by configuring
~/.zshrc and by adding a
SendEnv block to the local
Host duo_test Hostname duo-test.sbgrid.org SendEnv DUO_PASSCODE
For non-interactive connections (
call must be used for
DUO_PUSH, otherwise they will hang and timeout.

These commands are non-interactive, so there is not analogous menu for push/call/sms - if the
DUO_PASSCODE environmental method isn't set, this will use your default method.
