Trouble installing SmartClient on MacOS Sierra

Sebastian Roth

@Daniel-Miller I have read you message at least four times now but I still don’t fully understand.

That was just substituting StoreLocation.CurrentUser for StoreLocation.LocalMachine in GenericSetup.cs, yes?

Yes I think so. Just checked the diff I had lying around:

but something about how the installer is built isn’t getting the auxiliary files (.sh, .dll, etc.) packed with the executable

Can you be more specific on what’s going wrong here or why you think the files are not packed?

Which version are you trying to build from? Latest master? Since we talked about this last in June (!) I have pushed a commit to update dependencies. This is causing a bit of trouble and I have not found the time to properly get this right again. Please use commit b2995511 for now! Sorry for that.

You might also want to change the build script to get more output:

@Sebastian-Roth
That diff matches the one I had for GenericSetup.cs.

Lots of little things, like Visual Studio complaining about the name of OSX-FOG-TRAY.ZIP (renamed it to make it happy, but don’t know if I found all the references), SmartInstaller.exe only being 4.5 MB, and initial error messages about not being able to find Zazzles.dll when running the executable. Resynches off the current master and that commit seems to do the same thing, so I’m almost certain it’s something wrong with how my environment is set up and very likely due to MS not distributing ilmerge any more. Does this GitHub for ILMerge look like the same beast?

And this is all assuming I am actually synching to the points I am intending to … I’m a little new to using source control.

Good.

Right, I keep forgetting about this one. Should have fixed that a long time ago. I usually rename it after cloning the fresh source and soon forget about it. It’s good others look into this as well.

Yes, sounds very much like it. Something I have not noticed yet as we have our build environment set up since a long time. Good three years ago when I updated the build instrcutions in README.md the download from Microsoft still was available. The one you found in github looks very promising but seems like there are no official MSI releases that you can simply install as it used to. I will look into that and get back to you in a few hours.

And this is all assuming I am actually synching to the points I am intending to … I’m a little new to using source control.

What you usually do on the command line - and I assume you have the same options in a GUI GIT tool:

Clone a copy of the repo - you can skip that as you’ve already done that: git clone https://github.com/FOGproject/fog-client
Now the repo is on master branch latest version and you want to checkout a different version: cd fog-client; git ccheckout b2995511
Open the project in Visual Studio - or reload if you had it open already!

Sebastian Roth

@Daniel-Miller Have not found the time to work on this but doing a bit more search engine foo I found this: https://github.com/mono/nuget/blob/master/Tools/ILMerge/ILMerge.msi

You might use that older version of ILMerge till we get the other one ready.

Daniel Miller

@Sebastian-Roth Seems to be a lot happier on the build side, but the exe is still a bit anemic, only 6.2MB as opposed to the 8.9MB that is on my servers. It does run and properly relaunches, so the requisite dlls are there, but fails during the Installing Files stage with errors in the log

 9/11/2019 4:59 PM Installer ERROR: Method: <Install>b__0
 9/11/2019 4:59 PM Installer ERROR: Central Directory corrupt.

I would guess the service scripts, tray executables, etc. still aren’t getting bundled in.

Looking at the build script, I don’t see where they get attached, or are those supposed to be configured as resources in the properties for UniversalInstaller?

Sebastian Roth

@Daniel-Miller Yeah, still sounds like there is something missing. Try removing the | out-null at the end of the lines to get more output from the commands in build.ps1. As well you might want to try this if you have a Windows PC at hand: Copy the SmartInstaller.exe over to that PC and use 7-Zip to extract the EXE file. Within the extracted files you find one that is several MB in size called .text. Again, rightclick that file and use 7-Zip to extract it. It will do some extraction but also print an error message. But again you should have files extracted. How many files does it extract from your binary on the second run?

9/11/2019 4:59 PM Installer ERROR: Method: <Install>b__0
9/11/2019 4:59 PM Installer ERROR: Central Directory corrupt.

I haven’t seen this error before. I’ve dug through the code but can’t seem to figure out why it says b__0!? When extracting manually as described above you get filenames like Zazzles and so on.

Daniel Miller

@Sebastian-Roth Never seen that error before, you say? Now don’t I feel special.
Extracting .text gives me 50 files and they seem to reasonably match (by filename and checksum) the 48 extracted from production version. Extra files are a Modulespt and ShutdownGUIpt.

Google-foo indicates the “Central Directory corrupt” error results from some interaction with a zip archive and the b__0 might be a reference to some helper class. Only place I’m seeing in the install process that might bump into that would be the extraction of osxfogtray.zip. I still don’t see where that zip gets bundled in either the working build or the production build, but just for ho-hos I decided to take a peek at what that file looks like and it appears to be 0 bytes in size. As that probably isn’t right for a zip archive, I checked the repo and oddly enough the file ./UniversalInstaller/Scripts/OSX-FOG-TRAY.zip is 0 bytes in size and it looks like it has been that way since the initial commit.

Sebastian Roth

@Daniel-Miller Ohhh gosh!! I see our build process is pretty well messed up. Sorry for all the issues you run into and wast all your time on.

Please download the OSX Tray ZIP here for now: https://github.com/FOGProject/fog-client/releases/download/0.11.16/OSXFOGTray.zip

Thank you very much for sticking around even though things are not going very well. We just don’t have enough people to help out and work on all the different FOG components and so things get messy - too bad.

Daniel Miller

@Sebastian-Roth it’s almost like an open source project depends on free labor or something …

All right, still don’t see how that gets brought it, but it is building, a healthy 8.75 MB, and the installation process is now happy with the install files segment. But now we’re back to the Cert Pinning issue, however (names changed to protect the guilty).

Unless I’m missing something, those are the changes you made, yes? I am a bit confused about why it is trying to throw it in /usr/share. There has been a change in the version of mono (6.0.0.327), but running the version of SmartInstaller.exe you sent works as expected when executed under the context of root.

There anything else I should need to clean out other than SetupHelper.* in ./bin to make sure it has the right version in the exe build? Other thoughts?

Injecting root CA

Obviously we have missed RSA.cs in Zazzles! There are two places in that code file, line 155 and line 202.

Zazzles is another github repo you need to clone and open in Visual Studio. I’d suggest you don’t use the latest master but checkout commit 0f13a4caf as I have messed with the external libraries here as well. After it’s built you need to manually copy the new Zazzles.dll over to your fog-client\libs (from the top of my head I think this is the correct location) folder, close Zazzles project in Visual Studio, reopen fog-client project and re-build the solution.

We are getting there!

If for some reason FOGService is not properly starting or you see some very strange behaviour, then let me know. Don’t waste your time to try and figure it out. It is possible that I got something wrong with the hints here - writing this while sitting in the train and don’t have all my tools here.

Daniel Miller

@Sebastian-Roth Alrightly, rebuilt Zazzles with the change and now the installer is happy. FOGService isn’t starting, however, or at least fog tray isn’t starting and when I manually start it it is complaining about not being able to connect to the bus.

So, it looks like the service works, but the daemon and user agent aren’t loaded correctly. I actually don’t see where those service loads happen during install. I would expect they would be handled in Install() in MacInstall.cs as Uninstall() calls unload for the services, but the only reference I see to the load call are in StartService() in MacUpdate.cs and the OnUpdate event handler in FogUserService.cs.

Sebastian Roth

@Daniel-Miller Hmm, making progress!

It’s strange you get the Middleware::Response Invalid host when starting as root. Is this host registered with FOG yet? If not, manually register it. If it is, then reset encryption data in the FOG web UI settings for this particular host.

I actually don’t see where those service loads happen during install.

I think this is what you are looking for: https://github.com/FOGProject/fog-client/blob/master/UniversalInstaller/UniversalInstaller.cs#L418 (called here I suppose)

@Sebastian-Roth The Middleware::Response Invalid host was expected; the host wasn’t registered at the time of the initial query. It is now and producing logs like:

Fair warning: some of this is likely just me getting familiar with the code base… correct me as necessary.

That code segment kicks off the script that starts fogservice.exe after installation, but it is only executed when the OS is linux (UniversalInstaller.cs#L308). But if fogservice.exe were to start for macOS, I don’t see any place in fogservice that registers org.freeghost.daemon.plist as something to be started automatically by the operating system.

The (limited) documentation (Apple Terminal Users Guide, launchctl man page), a blog post, and more misc. google-foo seems to show a consensus that services are loaded via launchctl. I do see that the expected calls to launchctl exist in UpdateHelper (using the legacy load/unload invocations), but I am having some difficulty tracing the execution back through Zazzles updater abstraction to there. On the surface it appears to rely on the existence of SmartInstaller.exe, so I would assume (possibly incorrectly) that the update code is only invoked when an update is called for by the fog server. In this case, the call to launchctl never happens, the services (system daemon and user agent) are never registered, and the daemon doesn’t start on reboot. That would be consistent with an empty fog.log as I found.

This is of course assuming there isn’t another means of registering the daemons in use, in which case It would be helpful to know what the intended implementation was so I can take a look at how it’s breaking. Otherwise, I will likely try adding in the launchctl invocations to Install() when I have some time to test again.

@Daniel-Miller Thanks for the update. I myself have not used fog-client on Mac OS X yet I have to admit. So I can’t say for sure it should load after install and on reboots or not. In the wiki it says it should: https://wiki.fogproject.org/wiki/index.php/FOG_Client#Installing_-_OSX

But an older forum topic tells me that someone had this kind of issue before and here it doesn’t look like this was solved really: https://forums.fogproject.org/topic/7403/fog-client-on-mac-os-x

@Sebastian-Roth Added in the launchctl invocation for org.freeghost.daemon.plist at the end of Install() and things now appear to be behaving per the Wiki; the system daemon and user agent start automatically on reboot. It should be noted that the launchctl invocation both starts the system daemon and registers it for restart, but the user service won’t appear until reboot. Probably should have someone look to style and location of the logic. It may make sense to add something to the IInstall interface in case other environmental issues need to be addressed for other OSs later. Likely should add something to capture the relevant environment elements that trigger the relaunch for troubleshooting, particularly to capture the state during automated installs, but the Log class wasn’t cooperating with me. Otherwise, it should be ready for some sort of functional review and testing.

How would you like to proceed?

@Daniel-Miller Great! Do you have a github account? Would be great if we could work it in that way. Probably good to change to chat for that now. Check the speech bubble in the top right corner.
