Topic: Trouble getting through capture page workaround
Hello everybody.
Just got my first Chumby. Definitely won't be my last. But I first need to get past my capture page and log on. I saw the workaround on the wiki, but don't know how to change the script to work with my page. Here is a snippet from the source code.

Any help on how I should change the script would be hugely appreciated.
#!/bin/sh
# bind to wifi network...replace "mysid" with the ESSID
iwconfig rausb0 essid "mysid"
# DHCP config; should be pretty standard
udhcpc -t 5 -n -p /var/run/udhcpc.rausb0.pid -i rausb0
# this outputs your IP address from the dhcp connect...you may need it (I did)
IP=`ifconfig rausb0 | perl -n -e 'if (m/inet addr:([\d\.]+)/g) { print $1 }'`;
fbwrite "$IP"
# post to capture login page. this has to be customized per form (I needed the ip addy from above for the source field)
# the -k is for the insecure https connection; you can remove if the post is to http:// rather than https://
OP=`curl -k -d "_FORM_SUBMIT=1" -d "which_form=guest" -d "bs_email=email@foo.bar" -d "source=10.12.44.66" https://10.34.23.27/login.pl`;
## if you need further debugging, uncomment the next line
fbwrite "$OP"
