When attempting to run a remote binary using sudo on the remote box:
ssh remotehost "sudo ./binary"
I see this error:
sudo: no tty present and no askpass program specified
How can I work around this?
A simple way is to specify -t:
ssh -t remotehost "sudo ./binary"
From the man page:
Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty.
I cannot explain exactly why this works, and there may be a better way. I'd like to hear about it if so :)
@psusi explains why this works in a comment below.
