Trouble calling 'startx' in Start-Up Script

Hello everyone! This is my first post!

I'm trying to set-up a Thin Client that when booted will automatically log into a server for vnc.
Right now, I have a bash shell script at /etc/rc.d/thinclient
Code:
#!/bin/sh

echo "thinclient script starting..."

SERVER_IP="192.168.1.124"
STARTX_PATH="/usr/local/bin/startx"
VNCVIEWER_PATH="/usr/local/bin/vncviewer"
VNCVIEWER_ARGUMENTS="localhost:1 -geometry 1280x1024 -passwd /etc/thinclient/vncpasswd"

echo "Step 1: Attempting ssh connection as 'ThinAccount' to server at $SERVER_IP"
/usr/bin/ssh -f -i /etc/thinclient/id_rsa -L 5901:localhost:5900 -N ThinAccount@$SERVER_IP

echo "Step 2: *Unimplemented* Server will attempt connection to ThinClient"

echo "Step 3: Calling 'startx' with 'vncviewer'"
$STARTX_PATH $VNCVIEWER_PATH $VNCVIEWER_ARGUMENTS
I know that all my lines of code work, because the script runs as expected if executed after having logged in.
Code:
login: root
password:
FreeBSD-ThinClient# cd /etc/rc.d
FreeBSD-ThinClient# ./thinclient
Typing all that produces the expected result, filling the screen with wonderful, fullscreen VNC goodness.
However, I want the result without the typing, at startup.

The only clue I have is the output at startup.
Check it out!
Code:
/etc/rc: WARNING: Ignoring scratch file /etc/rc.d/thinclient~
thinclient script starting...
Step 1: Attempting ssh connection as 'ThinAccount' to server at 192.168.1.124
Step 2: *Unimplemented* Server will attempt connection to ThinClient
Step 3: Calling 'startx' with 'vncviewer'
xauth: not found
xauth: not found
xauth: not found
xauth: not found
xauth: not found
xinit: not found
xauth: not found
...
login:
Seemingly, the problem is that xorg cannot properly start. But why?

Any help from the friendly FreeBSD community would be much appreciated! Could the problem be not having a $PATH variable?

Dang, yo!

I feel like a fool! But at the same time I feel good, because my script is working.
It was just the missing $PATH variable. Oh well.

Is there a more elegant solution than just adding:
Code:
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
?

Now I have a new problem, that being that my script doesn't finish, so sshd, for example, doesn't get started.
Is there a better place to put this script?

Thanks again,
-Peter

TMTOWTDI. You could run it from /etc/rc.local. /etc/ttys is another way, and that leaves the rest of the system fairly normal. Set up an auto-login entry in /etc/gettytab and use that with the ttys entry.

Also: sh != bash, and using either for root's shell can make for some interesting times later.

You could perhaps add '&' to the end of the startx command to move it to background, so the script finishes.

Or you could create another script called 'start_thinclient' which simply runs your thinclient script with an '&' on the end to move the whole script into the background.

Thank you to both of you!

I learned a lot trying wblock's suggestions, but I eventually decided that, for security reasons, I actually don't want any users logged in.

Strangely enough, adding '&' to the end of the startx command didn't work. If I remember correctly, it managed to black out the screen. However, creating a 'start_thinclient' script in /etc/rc.d/ and in that running my main script in the background worked great!

Excellent!

Not sure exactly what you mean, but avoiding the autologin means you'll be running as root. An autologin entry doesn't show a login, it just logs in automatically. In this case, as a non-root user to run X. Because I've done this several times but forget how each time, I'm going to show it here:

/etc/gettytab
Code:
# WB: autologin console as user "user"
A|Al|Autologin console:\
        :ht:np:sp#115200:al=user
Then use that entry in ttys so user will automatically log in when the system starts that ttyv (at startup):
/etc/ttys
Code:
ttyv1   "/usr/libexec/getty Al"       xterm  on  secure
user's shell is set to /bin/csh in /etc/passwd.

Finally, add code to start X in "user"'s shell startup. For csh(1), it goes at the end of .cshrc.
/home/usr/.cshrc
Code:
# WB: startx if it isn't already running
set XPID = `/usr/bin/pgrep xinit`
if ( { [ -n "$XPID" ] } ) then
  #echo "X is already running"
else
  startx
  logout
endif
X will use the .xinitrc in user's home directory.
