I am just about to setup new IOS XR devices (ASR 9901 and NCS 540) and I am encountering a silly problem : when connecting to the devices with SSH from a mac os x client, all the terminal keys are disabled and not recognized (arrow keys, cli completion, ...).
With the same terminal client and using the serial console, the problem is not present.
Also from the same terminal client, if I ssh to a linux host and then ssh to the XR device, the problem is not present.
So it seams that using a SSH session from a macos X client trigger something on the IOS XR side that disable all vt100 key recognition.
The problem is not present when accessing classical IOS devices.

So the problem here seam to be "PTY allocation request failed on channel 0".
Looking at my .ssh config file, I found out that I was using the following options :
