The following URL works on the DCS-934L you may try it on the 932L and see if works.
wget -q --output-document test.html "http://admin:
[email protected]:80/setSystemFTP?ReplySuccessPage=upload.htm&ReplyErrorPage=upload.htm&FTPScheduleEnable=0&ConfigSystemFTP=Save"
Just replace FTPScheduleEnable=0 with FTPScheduleEnable=1
Please Note I found on the DCS-934L with the newest firmware (1.05.04) the wget will fail. I had to revert back to firmware version 1.03.01 to get this to work.
