Custom Full Host Registration for 1.3.4

george1421

@JGallo said in Custom Full Host Registration for 1.3.4:

I get a chainlink error and could not boot: input/output error followed by the ipxe.org link

What we need there is to capture this chainlink error. With that patched file installed call the following url from a browser and post the results here. http://<fog_server_ip>/fog/service/ipxe/boot.php?mac=00:00:00:00:00:00` That will provide us with the text that is used to create the iPXE boot menu.

@JGallo And this what you get when you call the boot.php file with the mac address I gave you?

If so can you tail the apache error log and see if php is throwing an error. This IS an incomplete iPXE menu, which means that something is wrong with that patched file.

The head of a valid ipxe menu should look like this:

#!ipxe
set fog-ip 192.168.1.53
set fog-webroot fog
set boot-url http://${fog-ip}/${fog-webroot}

JGallo

@george1421 That is what I get. I will try to tail the apache logs and see if anything I can get there. If I restore the the original boot.php file, should expect different results when calling the boot.php file with the mac address: 00:00:00:00:00:00?

george1421

@JGallo I would expect your results to be similar to my (unpatched) results. You could always try mac address 00:00:00:00:00:01 if for some reason you have mac address 00:00:00:00:00:00 registered. The key is to pick a mac address that should not exist in your FOG server.

@JGallo It looks like line 1168 is causing the error in the patched boot menu file.

From DM: The OP is also using the ldap plugin too. Only worth mentioning since the error being thrown is referencing attemptLogin().

[editor note] I fixed the previous thread to include the error log in a code block for easier review[end note]

Tom Elliott

I’m sorry, you’ll need to install the working branch then. I’ve moved attemptLogin to fogbase now and it appears the changes I suggested, I overlooked that change sorry.

Tom Elliott

So I pushed up RC-2 for 1.4.0 in a semi-official manner rather than have you jump directly on working branch.

JGallo

@Tom-Elliott Thank you. I went ahead and updated to 1.4.0-rc-2 and it seems like like post init scripts are running because I get a message that says Patching registration files and eventually states that it’s Done Patching Registration files. Unfortunately it’s not copying the file I have set up to copy. So we know that the post init scripts are running. Not sure if the copy script is working because when testing a host by trying to do a full register of a host I still get asked questions I removed from my custom fog.man.reg

JGallo

@Tom-Elliott @george1421 This is what I have as far as post init scripts:

code for fog.postinit

#!/bin/bash
## This file serves as a starting point to call your custom pre-imaging/post init loading scripts.
## <SCRIPTNAME> should be changed to the script you're planning to use.
## Syntax of post init scripts are
. ${postinitpath}fog.postselect

code for fog.postselect

#!/bin/bash
. /usr/share/fog/lib/funcs.sh
# place script commands here that should execute every time for every FOS action
# I added some additional check here just in case you wanted to highly customize the postinit script's actions. This section is not mandatory.
if [[ -n $mode && $mode != +(*debug*) && -z $type ]]; then
    case $mode in
        wipe)
            # fog wipe disk

        checkdisk)

        manreg)
            # fog full registration
            . ${postinitpath}patch.fullreg
            ;;
        inventory)
            # fog full inventory
            ;;
        quickimage)
            # fog quick image
            ;;
        *)
            # all other generic operations
            ;;
    esac
    # place script commands here that should be run for any of the utility functions
else
    case $type in
        down)
            # fog image deploy
            ;;
        up)
            # fog image capture
            ;;
        *)
            # the code should never get here, we'll just add so the script doesn't break
            ;;
    esac
    # place script commands here that should be run for either image capture or deploy
fi

code for patch.fullreg

#!/bin/bash

dots "Patching Registration files"
debugPause

cp -f ${postinitpath}fog.reg.man.fix /bin/fog.reg.man

dots "Done Patching Registration files"

and finally the custom code I modified that removed questions we don’t need to be asked during full host registration

@JGallo OK the forum really manged your code in the post.

Let go back to basics. Insert this code in your fog.postinit


echo "Installing Patch"
debugPause

cp -f ${postinitpath}fog.reg.man.fix /bin/fog.reg.man

echo "Done Patching"
debugPause

If that doesn’t work then we will need to install the debug kernel parameters again and figure out what is going wrong on the other end. If you see the Installing Patch in registration mode then we know the script is being called.

JGallo

@george1421 Yes. It is successful in echoing those words. I went as far as actually echoing “Installing my patch” and it works. LOL. So we know the script is being called but not too sure on the file copy. If I place the debug flags back, can I pull the fog.man.reg file to inspect it and confirm the file copy?

george1421

@JGallo Right in the code I provided, if you are in debug mode it will pause just before copying the file and just after copying the file.

On the pause just after copying the file press ctrl-c to break out of the script. Then inspect the file date. If its not correct then manually key in the copy command to see what error is thrown. I might suspect I have the source path off for some reason.

You might also want to key in echo "${postinitpath}" on the command line (after the control-c) to see if the postinitpath is properly set.

JGallo

@george1421 So placed the debug flags back. Once the patching was done, I hit control-c and inspected /bin/fog.man.reg and looks like the original file because my changes aren’t there. I also echoed the postinitpath and it returned a blank line.

Could I theoretically set the postinit path prior to cp the custom fog script? Or instead of using the variable postinit to manually enter the postinitpath?

george1421

@JGallo well in this case the postinitpath should be set by the master fog script. If it is not set correctly then things will fall down.

You could manually set it, but if you are still in debug mode, could you post the output of this command df -h at this point for the postinitpath to work, the FOS engine needs a connection back to the fog server over nfs to reach the script. Since the postinit script…

Wait that variable needs to be set, because the main fog program calls the postinit by issuing . ${postinitpath}fog.postinit

Instead of having you keep thrashing this around let me look at it tonight, there has to be something missing.

JGallo

@george1421 I will wait. While in debug mode, I typed

df -h

and got

filesystem             Mounted on
/dev/root                 /

@george1421 said in Custom Full Host Registration for 1.3.4:

echo “Installing Patch”
debugPause

cp -f ${postinitpath}fog.reg.man.fix /bin/fog.reg.man

echo “Done Patching”
debugPause

I might recommend a script of:

currfile="/bin/fog.man.reg"
newfile="${postinitpath}fog.reg.man.fix"

. /usr/share/fog/lib/funcs.sh

echo "Testing path for our fixed file at ${postinitpath}fog.man.reg.fix"
debugPause

# Test path and run copy if found and matched.
if [[ -r $newfile ]]; then
    echo "Found file preparing to copy"
    debugPause
    cp -f $newfile $currfile >/dev/null 2>&1
    [[ ! $? -eq 0 ]] && echo "Copy Failed" || echo "Copy Succeeded"
    debugPause
else
    echo "Failed to find file sorry"
    debugPause
fi

@JGallo Ok setting this up on my home dev box, I’ve come to the conclusion that this works as I outlined IF I would have frick’n spelled the manual registration file correctly.

the real name is /bin/fog.man.reg and not fog.reg.man

Even Tom missed it because he copied my script to start with.

Using tom’s script but with the proper file names it works. It was working with the file names I was using, except it didn’t overwrite the manual registration file.

[moderator note, I’m going to correct Tom’s post to reflect the proper file names in question]

JGallo

@george1421 LOL wow and of course it works now. I’m glad this was figured out. Making the changes and testing the scripts I can confirm that it works.

With that said, taking a step further, is the fog.postinit script suppose to have anything other than calling our custom scripts? Or should we skip the additional scripts (as you recommended earlier in the post ex - patch.fullreg, fog.postselect)? Once again thank you for taking a look at that. I’m glad there were some discoveries along the way that I’m sure will be useful for many others.
