      I have used this in the past to get additional information on a host but it doesn’t work any longer.
      https://forums.fogproject.org/topic/7740/the-magical-mystical-fog-post-download-script/3
      the /tmp/hinfo.txt file isn’t created and after executing the wget command from debug i get this:

      wget -q -O /tmp/hinfo.txt "http://${web}service/hostinfo.php?mac=$mac"
      wget: bad port spec 'http:'
      

      any help would be greatly appreciated.

        @greg-plamondon Thank you I’ll update the tutorial with the new information too.

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

          Change anything: No you are just telling wget to not pass the user agent parameters to FOG.

          CURL: Just replace the wget line with the curl line Tom posted. Same results just a different tool. The fog code has been updated (under the hood) to only use curl. There may be a time where curl specific calls are used. But today both work interchangeably.

          I had to use the -A option for curl to specify the user agent.

          curl -A "" -Lkso /tmp/hinfo.sh ${web}/service/hostinfo.php -d "mac=$mac" 
          

          That worked like a charm!
          Thanks @george1421 @Tom-Elliott

              Thanks @george1421 that worked.
              do i need to change anything when running that from my fog.postdownload?

              How would I make this use curl?

              curl -A "" -Lkso /tmp/hinfo.sh ${web}/service/hostinfo.php -d "mac=$mac"

                @greg-plamondon it’s preferred to use curl over wget. Curl doesn’t send a user afebt natively so your curl would look something like

                curl -Lkso /tmp/hinfo.sh ${web}/fog/service/hinfo.php -d “mac=$mac”

                I get the same result with the above.
                if I echo $web i get:

                http://192.168.10.238/fog/
                

                I changed what you had to:

                curl -Lkso /tmp/hinfo.sh ${web}fog/service/hostinfo.php -d "mac=$mac"
                

                I create a deploy debug task for a host.
                I type fog at the shell.
                i break out of the script after nfs is mounted.
                I cd to /images/postdownloadscripts
                ./fog.postdownload
                my fog.postdown;load looks like:

                I then type echo $location and i get nothing…
                I verified that the /tmp/hinfo.sh exists.
                If i cat /tmp/hinfo.sh i get:

                    @greg-plamondon It needs to be left in there. The fog code switched over from wget to curl and the FOG application checks to see if is a browser connecting and blocks it. Its that stupid security stuff again. 😉

                    The --user-agent=“” tells wget to not send (blank) a user agent string.

                      @george1421 I don’t have access to the exact code at the moment, but it should be something like this:

                      wget -q --user-agent="" -O /tmp/hinfo.txt "$web/service/hostinfo.php?mac=$mac" 
                      

                      and that’s just for testing and i should leave it the other way when using in post init scripts?

                          @greg-plamondon Yep its working. You have to pass the calling device as null. I know that doesn’t make sense. Let me look it up.

                            It depends on how/where you execute that script. The proper URL for testing is

                            http://<fog_server_ip>/fog/service/hostinfo.php?mac=$mac
                            

                            The bad port makes me thing the parameter ${web} is not being expanded correctly.

                            The command echo $web returned the proper server url so I changed it to:

                            wget -q -O /tmp/hinfo.txt "$web/service/hostinfo.php?mac=$mac" 
                            

                            The file hinfo.txt is created in /tmp but if you cat the file you get:

                            Cannot view from browser

                              @greg-plamondon remove the http from your cmd. We pass in the http:// with the $web variable. So your command is doing http://http://fogserver/…

                                It depends on how/where you execute that script. The proper URL for testing is

                                http://<fog_server_ip>/fog/service/hostinfo.php?mac=$mac
                                

                                The bad port makes me thing the parameter ${web} is not being expanded correctly.
