Fedora-version of sysmonforlinux is failing (made for RHEL 8?)

[karekaa]

Describe the issue
We are using https://packages.microsoft.com/fedora/41/prod/ as source for among other packes, fetching sysmonforliux. This program is failing on an actual Fedora 41 Linux machine. The rpm package has actually an «.el8» postfix, hinting this was made under RHEL 8. When fetching a "rhel/9/" version - the same apply with an extension of «.el8», but this will actually run OK on a RHEL 9 machine.

Originally title:
«sysmonforlinux at packages.microsoft.com/fedora/41/prod/Packages/s/ is made for RHEL 8»
at:
microsoft/linux-package-repositories#211

When did the issue occur?
2025-04-01 (This is NOT a «april fools day» ticket ;-)

If applicable, what package did you attempt to install, and from which repo?
sysmonforlinux from this repo:
https://packages.microsoft.com/fedora/41/prod/Packages/s/

Steps to Reproduce

1. Start with a «vanilla» Fedora 41
2. Log in as root
3. wget https://packages.microsoft.com/fedora/41/prod/Packages/s/
4. grep sysmon index.html
5. wget https://packages.microsoft.com/fedora/41/prod/Packages/s/sysmonforlinux-1.3.5-0.el8.x86_64.rpm
6. dnf install -y sysmonforlinux-1.3.5-0.el8.x86_64.rpm
7. systemctl status sysmon.service
8. systemctl restart sysmon.service
9. systemctl status sysmon.service

Actual Result

~ $ ssh hostwithfedora systemctl start sysmon.service 
Job for sysmon.service failed because the control process exited with error code.
See "systemctl status sysmon.service" and "journalctl -xeu sysmon.service" for details.

Expected Result

Screenshots

Additional context
The solution might be to compile the sysmonforlinux on a Fedora 41 platform, and build the rpm from there.

Note:
Fedora 42 is coming quite soon (04/24/2025 ?) and is already available as Beta, so please make a working sysmonforlinux for:

• RHEL 9
• Fedora 41
• Fedora 42
• also soon to be release: RHEL 10

Hi - thanks for reporting this. It looks like we have a packaging problem which needs to be addressed. In the meantime, you can build Sysmon for Linux on Fedora (I just fixed a bug that caused a startup failure on Fedora). As you may know, Sysmon depends on SysinternalsEBPF. You can install the version available on - https://packages.microsoft.com/fedora/40/prod/Packages/s/sysinternalsebpf-1.4.0-0.el8.x86_64.rpm

and then build Sysmon.
