Why can't I get my remote host into a variable?

Why can't I get my remote host into a variable?

[Lists]

Zsh 4.2.5 on FreeBSD.  I'm ssh'ing into the FreeBSD machine.

I'm trying to get my remote host into a variable REMOTE_HOST.  I have 
tried both of these in .zshenv:

REMOTE_HOST=`who am i | awk '{print $NF}'|tr -d '(|)'`

$ who am i
luomat           ttyp0    Nov 30 19:34 (192.168.1.103)

That works on the commandline, but when I try it in .zshenv I get 
"19:34" or whatever the timestamp is for that session.

Thinking I would be clever, I tried this

TTYSHORT=`echo $TTY |colrm 1 8`
REMOTE_HOST=`w | fgrep $TTYSHORT | awk '{print $3}'`

but that does not work either.

Anyone know how to get this to work in .zshenv?

You're presuming that the utmp/x is updated by the time zsh runs.
I wouldn't.  It's most likely to be asynchronous.

Instead, see which environmental variables sshd provides for you:
i.e. check if  SSH_CLIENT  or  SSH_CONNECTION  is available to you
and parse one of them.
