Communication problems between fog client and server


  • Hi,

    We are working with FOG since many years in our school and i want to say thanks for the work you do on that project it’s a really good tool for many persons :-).

    I just build a new FOG server 1.5.9 on Debian 10.6, before our server was on Ubuntu… All installation is fine, we can deploy & capture images without any problems.

    The last point is fog clients, it seems communication between clients and server is not that good. Cert is ok but got many “Middleware::Response ERROR: Unable to get subsection” errors in quite all sections in the fog.log filefog.log .
    So no tasks seems being accepted by clients, either rename, ad join or deploy.

    On the file i uploadfog.log this the “fogserver” for the server name is use by a msi client, but i have the same problem/messages on a other machine installed with the smart installer where i indicate the ip address instead of the “fogserver” for the server name.
    Whatever a “nslookup fogserver” on clients is correctly resolve.

    I also use “Reset encryption data” on the first one but it not help at all.

    If you guys have some idead to help us, could be very fine :-).

    Regards

    @LittleTux Thanks for the feedback on this!


  • @sebastian-roth Thanks again for all the help.

    Fresh install is fine, and client is updating well by GPO.

    We can pass this to solved :-).

    Have a good day, regards.


  • @sebastian-roth Well read this kinda too late … 🙂
    At this moment, fog install is running on a fresh new install.

    I will let you know if it’s good for me for client/server communication after.

    Have a good day.

    @LittleTux Before you go ahead an reinstall the whole server let’s take a look at the files the fog-client uses to pin and talk to that server. Possibly I just missed creating one of the files last time or you have a mixed up web root. Please run the following commands and post output here:

    ls -alR /var/www/fog/management/other/
    ls -alR /var/www/html/fog/management/other/
    ls -al /var/www/
    

  • @sebastian-roth Hi again Sebastian, thanks again a lot for the time you spend to fix my issue …

    Tried 2 things and get the same result/error :

    -Deploy the fresh msi 0.12 client fog installer you download from Github by GPO :

    As you see, the GPO is working great as the version is update after a reboot but we got that certificate error

    • Tried to desinstall fog client and reinstall with the same the fresh msi 0.12 client fog installer you download from Github on a test pc and have the exact same error about certificate

    You have already spend many times on my issue so i don’t want to busy you more …

    I assume that my problem is when i tried to copy old “/opt/snapins/ssl” repository to the new one.
    So if i install a new server from start without copying nothing, the client downloaded from the new server will work fine so i will deploy this client on my all network by GPO.

    Am i right ?

    Have a good day, regards.

    @LittleTux Please check the speech bubble in the top right corner.


  • @sebastian-roth Ok i see, this a screenshot of the things:

    72d8dbe1-bb62-485f-8d51-3159590472b0-image.png

    On the left, backup from the old Ubuntu server who is deleted

    On the right the actual server.

    Actually i see that he new server miss the .srvprivate.key file. But if i copy this one it will works ? This file come from the old server so i don’t know

    Important thing to note too is that the CA directory is empty on the new one and have 3 files and the old one :

    • .fogCA.key
      -.fogCA.pem
      -.fogCA.srl
      -.srl

    So there are two questions :

    • If i copy the .srvprivate.key file and the 4 file i nthe CA directory, it will works ?

    • Is there a way to relaunch the installation on the server without delete configurations and data (images, hosts, etc…) but with renitialize the certification ?

    Regards.

  • Moderator

    @LittleTux The other server has its own CA and certificates and it’s not a good idea to copy things over from that.

    From the output you posted we see that most of the files match (same fingerprints and verify OK) but the key file doesn’t!! This is causing the issue for sure.

    So let’s check the backup of the old files you have to see if we can get things back this way. How did you take that backup copy? Does it have the file .srvprivate.key in it (on Linux systems files starting with a dot are kind of hidden)?


  • @sebastian-roth Got this with the command, not sure is a good thing 🙂 :

    I manage another school network, FOG is 1.5.9 too on a Debian 9. I checked clients on this network and all seems ok for communication. Is there any way this server can help us ?

    Regards


  • @sebastian-roth “Did you copy this backup of the certificate, key and CA of your old server to the new install at some point yet?”

    To answer to this point i tried with WinScp from a Windows Server but i have some permissions errors then i don’t try again. I checked file versions and it seems to me that files in this directory was the one created during the installation and not the files of the old one.

    I try commands and feedback very soon.

    Have a good day, regards.

    @LittleTux I find it strange we see the “Data::RSA FOG Server CA cert found” and “Middleware::Authentication Cert OK” messages. As far as I see it this would mean the client does use the certificate provided by the new server already.

    I just backup the /opt/fog/snapins/ssl directory of the old one in case of certificate client/server issues :-).

    Did you copy this backup of the certificate, key and CA of your old server to the new install at some point yet?

    Please run the following commands to see if the certs are somehow messed up:

    openssl x509 -noout -fingerprint -md5 -in /opt/fog/snapins/ssl/CA/.fogCA.pem
    openssl x509 -noout -fingerprint -md5 -in /var/www/html/fog/management/other/ca.cert.pem
    
    openssl x509 -noout -modulus -in /var/www/fog/management/other/ssl/srvpublic.crt | openssl md5
    openssl rsa -noout -modulus -in /opt/fog/snapins/ssl/.srvprivate.key | openssl md5
    
    openssl verify -verbose -CAfile /opt/fog/snapins/ssl/CA/.fogCA.pem /var/www/fog/management/other/ssl/srvpublic.crt

  • @sebastian-roth Thanks for the answer, actually it’s a fresh new install on a Debian 10.6. I had to delete old FOG server after backup images/hosts/groups because we don’t have enough space on our SAN to have two at the same time (1 tera octects of images).
    I just backup the /opt/fog/snapins/ssl directory of the old one in case of certificate client/server issues :-).

    So no clients is working fine at this moment.

    On the client i got one “FOG Server CA”, “FOG Project CA” & “FOG Project” certificate.

    Have a good one, regards

  • Moderator

    @LittleTux Thanks for the update. So we are down to Middleware::Response Failed to decrypt data on server for all the hosts now. Do you see other clients working fine?

    Do you have more than one FOG server by any chance or did you re-install (not update) at some point?

    Please take a look at the Windows certificate store and see if you have more than one certificate named “FOG Server CA” on those hosts that show the issue.

    I will look through the code again later on.


  • @sebastian-roth Just deploy a image on a another pc. In this image i installed fog client with smart installer with the ip address of the server.

    That is what i have in the fog.log

    You are right, i assume the problem is here “01/12/2020 12:54:25 Middleware::Response Failed to decrypt data on server”

    Is there a way to check manually this point of the communication ?

    Or is there a way to reinitialize certification creation process on the server without modify anything else ?

    Regards.


  • @sebastian-roth Just testing this :

    • Approve DESKTOP-1210KMT
    • Reset Encryption data to be sure
    • stop/start FOGService

  • @sebastian-roth I’m not sure of what is calling external tools with FOG but we only use FOG as PXE/Image server on the network and our Domain Controller is the DHCP pointing Fog Server as PXE server.

    I effectly see the DESKTOP-1210KMT in the pending host list, this one is the last fog.log i upload.

    The first one, the who i delete the token.dat file is in the “normal” hosts list.

    Regards.

    @littletux said in Communication problems between fog client and server:

    01/12/2020 09:52:02 Middleware::Communication POST URL: http://10.149.20.67/fog/management/index.php?sub=requestClientInfo&authorize&newService

    That is really strange. Looks like this host is not registered on your FOG server. As a coincidence I have been digging through an issue with @JJ-Fullmer in the last weeks. In his case it turned out to be an issue initially not caused by FOG itself but PowerShell API calls used. Do you use external tools with FOG by any chance?

    Please check the web interface if you still see DESKTOP-1210KMT in the list? Maybe in the pending hosts list?


  • @sebastian-roth Just tested on another one :

    Installed fog client with the smart installer and specified server ip address during installation and got this after starting FOGService :
