Hi guys i recently installed Ubuntu on my desktop computer and am using a software which needs the port 80 to be open.The thing is it seems by default port 80 seems to be closed.I need to know how to open it for incoming traffic.I am new at Ubuntu and linux in particular so please be patient with me.I am not too sure about firewalls or how they block ports which is a common reply i got on many forums.Any suggestion to make this problem go away will be largely appreciated because i have been struggling with this for a week now.thanks in advance.
