如何从Linux访问树莓派localhost？

Question

I set up a php file in my raspberry pi so that I can access some files on it from my local network.

Within raspbian, it works well in any browser using localhost/test . I tested it also in a Windows and a Mac computer in the same network, using my.local.ip.address/test in my browsers and it also worked fine.

Now here is the problem: in my linux computer, it does not work. It simply says that "the site cannot be reached". I already tried disabling the firewall (UFW) but it doesn't change anything.

I also tried several browsers in linux and the result is the same.

I think I am overseeing something obvious but I cannot see it.

Could someone give me a pointer on what might be wrong?

ifconfig -a output (Linux machine)

ifconfig -a output (Raspberry Pi machine)

It's possible that your Ubuntu machine is not in the same network. You can try theses steps to confirm :

Ping

Go on your ubuntu machine and type :

ping <rasp.pi.local.ip.address>

Go on your Raspberry Pi and type :

ping <ubuntu.local.ip.address>

If the ping request do not succeed your machines are probably in different networks. Your can use this command to watch the path used by packets between your ubuntu machine and your Raspberry Pi :

traceroute <rasp.pi.local.ip.address>

Change network card settings

Before this step, check if your are able to connect your machines togather (switch, router, vlan...).

ifconfig <interface> down    
ifconfig <interface> <ip.network> netmask <netmask.network>
ifconfig <interface> up

After completing theses steps try to ping again and access to your website.
