Nodejs Websocket image upload not working on CentOS -

i implemented websocket file upload implementation described on: http://code.tutsplus.com/tutorials/how-to-create-a-resumable-video-uploade-in-node-js--net-25445

it worked great on ubuntu vm. when uploaded code centos 6 server, images didn't work when got uploaded. tried uploading big text file, , fine. tried zip, , still didn't work. file on server , file beingness uploaded have same file size appears work fine. can assume sort of character encoding issue? stuck. got ideas?

i'm tempted seek using ajax working if haven't made progress in next day or 2.

i found solution.i had apply new chain rule iptables,and allow server hear on custom port web sockets..after that,everything works great. had create permanent.
