1. Bring up an xterm: pwfs@vm-pwfsserver (from the k2aoserver-new VNC pull down)

2. ssh -X nfiudev@nfiuserver (the usual AO password for VNC)

3. [nfiudev@nfiuserver ~]$ cd src/sce

4 [nfiudev@nfiuserver sce]$ TrackCam tint 0 .002
[nfiudev@nfiuserver sce]$ ./psfDispTiny.py -s /tmp/TC_Display_images.im.shm

Another option is to bring up the VNC where the FIU camera is running an eavesdrop on that:

nfiuserver:2 <usual AO password>

Instructions for Restarting the PyWFS camera (Saffira): (from Sylvain)

Symptom: PyWFS Camera (in the PyWFS status) shows red and says it is powered off

Clicking on it and rebooting/restarting the camera server does NOT resolve this.

Solution:

1. Connect to the RTC: ssh -X prtc@prtcserver

2. showRTProcess: it opens a window and the 2^nd process from the top is partially crash

3. Ctrl-c to restart the process

4. Then connect to: ssh -X pwfs@vm-pwfsserver

5. Issue command: prtcRestartCOM (takes about 5 sec, then you should be able to reacquire the camera)
