      @george1421 said in Extended fog variables problem.:

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

        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!

          @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 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.

                @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:

                  #!/bin/bash
                  . /usr/share/fog/lib/funcs.sh

                  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:

                  Cannot view from browser

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

                      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.

                      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
