Here's a rough (there must be a thing or two I've forgotten but I think I was pretty thorough) outline for how to get the web cam for Barrow setup.

Here's an easy script to pull images from an Axis Q6032-E pan-tilt-zoom web cam. 

#!/bin/bash
## Pan Range:  -180 to +180
## Tilt Range: -20 to +200
## Zoom Range: 1 - 9999
wget --no-check-certificate -O /dev/null https://user:pass@axis-00408cb14f01.iarc.uaf.edu/axis-cgi/com/ptz.cgi?pan=-100&tilt=10&zoom=1 
sleep 5
wget --no-check-certificate -r -O /home/bob/working_files/barrow/webcam1/images/view1.jpg https://axis.iarc.uaf.edu/jpg/image.jpg
wget --no-check-certificate -O /dev/null https://axis.iarc.uaf.edu/axis-cgi/com/ptz.cgi?pan=-120&tilt=10&zoom=01 
sleep 5
wget --no-check-certificate -r -O /home/bob/working_files/barrow/webcam1/images/view2.jpg https://user:pass@axis-00408cb14f01.iarc.uaf.edu/jpg/image.jpg
wget --no-check-certificate -O /dev/null https://axis.iarc.uaf.edu/axis-cgi/com/ptz.cgi?pan=100&tilt=10&zoom=35 
sleep 5
wget --no-check-certificate -r -O /home/bob/working_files/barrow/webcam1/images/view3.jpg https://axis.iarc.uaf.edu/jpg/image.jpg

To view these images on the remote server you're running the script from, presuming imagemagick is installed:
First: 

ssh -Y to the server

Second: 

$ display view1.jpg

Here is one way to set up a DreamPlug to control this camera (also doubles as serial server):

  1. Log in as root (nosoup4u)
  2. passwd (change password)
  3. mkdir /home/bob
  4. adduser bob
  5. chown bob:bob /home/bob
  6. su bob
  7. mkdir .ssh
  8. cd .ssh
  9. ssh-keygen -t rsa -b 2048
  10. update /etc/apt/sources.list (backports.debian.org & comment out the internal ip line)
  11. apt-get update
  12. apt-get upgrade
  13. cat id_rsa.pub # copy the key
  14. ssh bob@datapro.iarc.uaf.edu
  15. cd .ssh
  16. paste key to /home/bob/.ssh/authorized_keys
  17. Disable wireless adapter: http://www.spinifex.com.au/plugs/dphowtowifiap.html
  18. Modify /etc/network/interfaces

  4. apt-get remove samba
  5. apt-get remove alsa-utils
  6. apt-get remove lighttpd
  7. apt-get remove ftpd
  8. SSH Port: 22
  9. add user to sudoers:
    1. chmod 4755 /usr/bin/sudo
  10. give general user crontab permissions:
    1. chmod 4755 /usr/bin/crontab
  11. DHCP Server is: udhcpd (default... added dhcp3 & dnsmasq and it confused things)
    1. To give axis camera a static IP over DHCP:

static_lease 00:40:8c:b1:4f:01 192.168.1.3 (in /etc/udhcpd.conf)

  1. to make the name known (dream2012.iarc.uaf.edu)
nano /etc/dhcp3/dhclient.conf
/send host-name "dream2012";
  1. to map the removable SD card modify /etc/fstab
/dev/sdb1   /var/pictures/  ext2  rw,noatime  0 0
  1. ser2net.conf config:
7808:raw:60:/dev/ttyUSB0:9600 8DATABITS NONE 1STOPBIT
7809:raw:60:/dev/ttyUSB1:9600 8DATABITS NONE 1STOPBIT
  1. IP Tables setup (This may not quite be up to date):
dream2012:~# iptables -L

target     prot opt source               destination
