Tried making an init script that writes to the wall on runlevel 0/6 , however it looks like the disconnect from ssh happens faster than the wall write (even though the reminder script is K01 and sshd is K25), guessing these are not serial ....

Sorry if my goal isn't clear. The idea is that if someone types "shutdown" that person gets a message on the screen that reminds them to put the box in maintenance on the host. So the person performing the shutdown wouldn't be adding the message

Why 64k limit? Is it a source port thing? If that is the case you can just add more 'servers' to the backend that are bound to different ports...
