Hostname changer not working

Pretty weird! Is xxx.xxx.xxx.xxx always the exact same IP address? Please make sure!

Why would one HTTP GET request work and another one the same minute not? Maybe just try this link in your webbrowser and see what response you get. Usually it should be like: ‘#!ok=<hostname> #AD=…’

Hi,
xxx.xxx.xxx.xxx is always the same IP address. I’m sure.
I have never seen ‘#!ok=<hostname> #AD=…’
I dont know why…

I meant that you could try to access this link http://xxx.xxx.xxx.xxx/fog/service/hostname.php?moduleid=hostnamechanger&mac=D4:3D:7E:D2:52:B4|&newService=1 (exchange xxx.xxx.xxx.xxx with the IP of your FOG server) in a normal browser from any host in your network which has access to the FOG server via HTTP (probably most if not all hosts will have access I guess). Then you should see something like ‘#!ok=<hostname> #AD=…’ in that browser window… or possibly an error. Give it a try!

@Uncle-Frank

when i try in a browser, i see “#!ih”

[Sebastian Roth]

I am sorry but I don’t know the code of the new client much yet. So I am not sure how the client would handle this response. Usually ‘#!ih’ means ‘invalid host’. What about if you access the other URLs you see in the log, e.g. http://xxx.xxx.xxx.xxx/fog/service/servicemodule-active.php?moduleid=hostnamechanger&mac=D4:3D:7E:D2:52:B4|&newService=1

By the way. Which version of FOG du you use (see in the blue cloud in the webinterface).

@Uncle-Frank my guess as to why he is seeing ih which is invalid host, is the MAC address being sent is the wifi while the Mac registered to the host is wired. This is just a guess.

@Uncle-Frank

when i try the other URL i have : “#!nh”

I’m in version 4682

This host as only wired LAN it’s not a laptop so i think it’s not a MAC address problem

[Sebastian Roth]

Sure you haven’t changed this client’s “Service settings” meanwhile? ‘#!nh’ to me sounds like hostnamechanger is not enabled for this client in the web interface. But maybe I am wrong.

[Tom Elliott]

@Uncle-Frank Absolutely correct.

@Tom-Elliott

Ok was my fault… for this host the hostname changer was disabled.
I activate it in service settings but it doesn’t work.
When i try the URL with hostname.php it keeps trying but nothing happens (so it explain the success for servicemodule-active.php and the error for hostname.php in this log)

You mean in a web browser?? Wow… this is… not as it should be I guess!

What do you see in the apache error logs while you try to access this URL from a browser. Depending on your distribution those files might be in /var/log/apache2/ or some similar path on the FOG server.
