My Linux machine is inaccessible by the IP address, as in only     http://127.0.0.1:8080/projectnameor localhost works on the browser, but     http://10.1.5.5:8080/projectnamedoess not (here 10.1.5.5 is my IP address as found out by typing ifconfig in terminal).I am using Fedora 16.Edit: output of iptables -L -n:Chain INPUT (policy ACCEPT)target     prot opt source               destination

IP Address inaccesible
networking;iptables;webserver
Your box has multiple interfaces. Each interface can have multiple IP addresses. (among others there is 127.0.0.1 on lo and 10.1.5.5 on eth0, or something like that. - See ip addr for details.)Now you have some kind of web server running on that box. To be accessible to others it has to bind to some interfaces or IP adresses.Somewhere in the config file of your web server you should find a listening or bind option specifying an which addresses the server binds.Currently it seems to only bind to 127.0.0.1, i.e. it is only accessible from your own box through the loopback interface. (see netstat -tpln for details.)If you want to make it accessible from everywhere change you can usually bind it to * or 0.0.0.0. - Have a look at your config documentation.
