SOLVED Extended fog variables problem.

[Greg Plamondon]

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.

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

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

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"

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

        getHardDisk
        if [[ -z $hd ]]; then
            handleError "Could not find hdd to use"

        fi
        getPartitions $hd
        for part in $parts; do
            true
        done
        dots "Mounting partition $part"
        ntfs-3g -o force,rw $part /ntfs >/dev/null 2>&1
        if [[ ! $? -eq 0 ]]; then
            echo "Failed"

        debugPause
        pccompany=${hostname:2:1}
        case $pccompany in
                        2)
                . ${postdownpath}fog.log
                . ${postdownpath}fog.bay_replace-files
                . ${postdownpath}fog.drivers
                . ${postdownpath}fog.ad
                ;;
                        5)
                . ${postdownpath}fog.log

                . ${postdownpath}fog.log
                . ${postdownpath}fog.jet_replace-files
                . ${postdownpath}fog.drivers
                . ${postdownpath}fog.ad
                ;;
                        *)
                . ${postdownpath}fog.log
                . ${postdownpath}fog.replace-files

        ;;
    *)
        echo "Invalid OS"
        debugPause
        return
        ;;
esac

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

@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”

[george1421]

@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 said in Extended fog variables problem.:

@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?

[george1421]

@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.

[Greg Plamondon]

@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

[Tom Elliott]

@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/…
