When trying to run the command ssh user@ip 'command'
, I keep receiving this error: can't get tty settingscan't set orig mode
. I have tried googling this and searching here but have not found anything referring to this message. I am trying to automate connecting to a Cisco wireless access point (2800 model) using Golang to run a command then exit, but this message pops up each time. I can log in normally using ssh user@ap_ip
, but using the shorthand ssh user@ap_ip 'command'
or trying the equivalent in Golang gives the error message above. Anyone know what's going on?

ssh without explicit command given will allocate a terminal while ssh with a command given will by default not. It looks like the command you execute needs a terminal. In this case use the
-t
option, i.e.ssh -t user@ip command
. From the documentation:-t Force pseudo-terminal 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.
