IP Address displayed in banner on RACHEL index.php

[needlestack]

From @spatiald on July 17, 2015 15:55

I think we should change the code this way:

ORIGINAL pulls the hostname IP which tends to return 127.0.1.1

<div id="ip">http://<?php echo gethostbyname(gethostname()); ?>/</div>

This is because the code pulls the hostname IP from /etc/hosts:

root@WRTD-303N-Server:/media/RACHEL/rachel# cat /etc/hosts
127.0.0.1   localhost
127.0.1.1   WRTD-303N-Server

PROPOSED

<div align="right" id="ip"><b>Server IP</b> </br><? echo $_SERVER["SERVER_ADDR"]; ?></div>

This is what the proposed solution looks like (caveat, I haven't tested in various IP scenarios yet...ie. connect to internet vs not connected to internet):

The 192.168.255.94 address is an internal network for me and the current eth0 interface on the CAP.

Copied from original issue: rachelproject/rachelplus#17

[needlestack]

I support this change - it solves another problem I've seen a few times, where in certain Windows configurations the function call is slow and causes the page to hang for several seconds before rendering.

The labeling is good too, though perhaps "Address" would be better than "IP"?

The only concern is that in Windows setups it might come up as "localhost" for the address, which wouldn't work on other machines. But I don't know that would be any worse than the issues we run into now. And RPi setups are far more common anyway.

I say go ahead!

Cheers, Jonathan

Along with Jonathan’s IP -> Server comment, should probably remove the word “RACHEL” as the banner says it quite proudly?

So we are all tracking…here is the revised line modified:

So the server address displayed on the main page is only the one the user puts in the address bar. It isn't the eth0 address. Is there a way for php or javascript to parse a file and display the contents? If so, I have a script that will drop ip list (one per line) of the eth0 and wlan0 addresses.

[needlestack]

From @bnordha on July 24, 2015 0:55

Isn’t it better that way?

I can think of scenarios where at the same location

• One set of users access directly via Wi-Fi, and hence go to 10.10.10.10
• While another set of users will access the content via the LAN, e.g. 192.168.1.15 Bernd

[needlestack]

From @spatiald on July 24, 2015 1:0

My thought is that you would display both the eth0 and wlan0 IPs…just a thought. The only concern I can think of is maybe the prison where you wouldn’t want to broadcast out your IP.

We changed it initially to make it easy to find out the eth0 IP and, if there was no IP on eth0, it would display 192.168.88.1 address.

I agree with displaying both. I don't think that's a problem for the prisons (broadcasing a LAN IP).

So right now, the IP displayed in the header is the IP the person is going to for RACHEL. My issue with that is that it is not really helpful. I was hoping someone might know a way to display the current WIFI and WAN IPs (parsed via javascript or some other means)? Web isn’t really my expertise. :) /s

So the original method -- <?php echo gethostbyname(gethostname()); ?> -- seemed to get the LAN IP on Windows (my testing environment), but it seems not to work on other systems (as well as sometimes being slow). Getting PHP to parse a file shouldn't be a problem -- but perhaps it's better to parse the output of something like ifconfig or ipconfig on Windows? In any case it's going to have to be smart enough to detect and work on different systems.

Reviving old thread - I am reworking the RACHEL index page at the moment and wanted to address this. I am going to make it use ifconfig (or ipconfig on windows) to look up the IP address of the server. Seems to work reliably for the ethernet address. I don't have a WiFi enabled PI so I don't know how the wifi shows up - Sam, you mentioned wlan0 - is that always the name of the interface? If so, I can pretty easily have it display both a LAN and WIFI address...

Let me know.

Yup - should be wlan0 on all the builds we are using (rasbian and ubuntu)

Yeah my OCD has always bothered me that it wasn't clean.

Thanks for working on that.  :)

This issue should really be moved to contentshell

[needlestack]

From @richsegal on April 9, 2016 22:46

Do we need the IP address at all? It is only really only useful on localhost to help administrators direct networked users to the correct host. Maybe it can be moved to the administration page?

I find it redundant and possible confusing to networked users who have already managed to type in the correct address to see the page in the first place. For powering potential, we configure our network so that http://rachel/ loads the RACHEL home page so it can only cause confusion in our environment.

[needlestack]

From @spatiald on April 9, 2016 23:37

Now that we have an admin page, I think that would be a good idea. Keeps the initial menu clean, too.

[needlestack]

Agreed

[needlestack]

One thing to note - the original reason I put the IP address in was for RACHEL usb - UwAmp would open a browser window on launch pointed to RACHEL, but there was no easy way to see how other users could access the system (the browser addressbar would just say localhost). So the IP address was helpful there. When we get to redoing RACHEL usb, I'll figure out how to best deal with that case. For the rest, I agree it's a distraction.

[needlestack]

Done. We'll see how we want to handle Windws/USB versions of RACHEL when we get to building a new version of that.
