Yes, it works.
Thanks a lot.

Hello,
on my clients Linux - Ubuntu 20 and CentOS 7 - when I stop FOGService, it takes exactly 1m30 to stop.
The version on the server is FOG 1.5.8 and the version on the clients is 0.11.19
I have not found any parameter which could explain that long time.
Thanks for your help,

@Sebastian-Roth said in I can't install the Fog client on CenOS 8:

https://www.mono-project.com/download/stable/#download-lin-centos

Thanks a lot. With this method it works.

Hum again. The packages that are to be installed are those of CentOS 7, and I should uninstall some packages on my CentOS 8, such as giflib and emacs, in order to install the mono packages…
The repo download.mono-project.com_repo_centos_ does not provide packages for CentOS 8

Hum. I’m quite sorry, I just see the solution on the Fog wiki; it works
(so you can add CentOS 8 in the list of Linux distros).

To install the Fog client, I used ‘mono SmartInstaller.exe’. But for CentOS 8, the rpm’s mono are now on the repo https://extras.getpagespeed.com/redhat/8/$basearch/
and I must pay to get them -which is not possible in my university.
I have tried to use the command mono that comes from the package of CentOS 7, but it does not work : the messages are

Is there another solution than using mono packages ?

Okay, now the client gets the information from the server without error and can execute a task launched from the server.
Thanks a lot.

No, there is not the 302 redirect in the log. It’s as if the server receives no demand from the client.
I don’t find the IP address of the client in the other files in /var/log/httpd.

The result is the same:
on the client the message error is again
“Communication ERROR: SSL connection error: System.Security.Cryptography.X509Certificates.X509ChainStatus[]”
and on the server nothing is logged.

@Sebastian-Roth said in CentOS 7 client fails to connect:

wget --no-check-certificate https://fogus/fog/management/other/ssl/srvpublic.crt

The log on the server is:

148.60.3.96 - - [27/Jan/2020:17:02:17 +0100] "GET /fog/management/other/ssl/srvpublic.crt HTTP/1.1" 200 1749 "-" "Wget/1.14 (linux-gnu)"
