Java Linux ServerSocket does not do much -


i running linux fedora 18 , want java code print hello linux in web browser type in http:// myhostname. have use code in windows , work find. in linux use port 80 got permission denied. use port 8080 no permission denied didn't work. using port 80 client dose accept , can send , receive information on machine seversocket not on different if connect ton network.last thing have made policy file allow port 80 work useless , still not sure set policy file in code. sorry if long question have been researching issue month not please don't tell me google it. guess main question why can't serversocket broadcast out of linux machine , how fix it?

thank

on linux, need root use system ports 0 1023. tomcat has ways of opening port 80 without leaving process running root, bit complicated discuss here. linux provides ways give permissions access these port, use port 8080.

if use port 8080, need redirect using router port 80, or have specify want connect port 8080. browser assumes port 80. e.g. http://yourhost:8080/

to connect server machine, firewalls have setup connect all. firewall designed stop traffic haven't explicitly allowed. means may need open firewall on server, , network router , put public ip address (not internal one) in hosts file of client.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
