Solved Checking for passwordless accounts: tee: /dev/stderr: No such file or directory

[jtocci]

I have a jail that is running periodic daily security. Lately I've been getting email that says::

Checking for passwordless accounts:
tee: /dev/stderr: No such file or directory

Which is odd, since it has /dev/stderr. When i go to the host I can run:

# echo "hello" | tee /dev/stderr
hello
hello

but if i do the same in this jail i get:

echo "hello" > /dev/stderr
sh: cannot create /dev/stderr: No such file or directory

if i do an ls -la i get:

root(4)nut:~ # ls -la /dev

on the host I get:

lrwxr-xr-x   1 root  wheel        4 Jul 26 17:21 stderr -> fd/2
lrwxr-xr-x   1 root  wheel        4 Jul 26 17:21 stdin -> fd/0
lrwxr-xr-x   1 root  wheel        4 Jul 26 17:21 stdout -> fd/1

So i am very confused. Any hints welcome.

Guessing on dates in your jail /dev/ contents, you did restart/remount something in there? Are /dev/fd/ entries intact?

Thank you yuripv79

I added the following lines to my devfs.rules and it's fixed

add path fd unhide
add path 'fd/*' unhide

thank you very much for your insight.
