Re: whitelisting with firewalld

You have tried:
1. IF packet comes FROM 192.168.122.6 THEN use the "public zone" rules
ELSE
2. IF packet arrives VIA eth0 THEN use the "public zone" rules

In other words both traffic types use the same set of allow/deny rules.

When you use two different zones, then different rules apply.

3) Install the CUDA SDK from the .run file
NVidia has a repository of CUDA RPMs. You might be able to install necessary packages "easier" than from the .run blob.

Are you sure iptables would die in RHEL 8? I was looking at Snapshot 4 earlier today (at work) and all of the stuff seems to be there. It is different to what's in RHEL7 a bit, but still available.
Genuine iptables or "wrappers"?

Re: Nvidia Quadro P2000 Driver RPMs

From ELRepo.org

Code: Select all

yum install https://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm
yum install nvidia-detect
nvidia-detect
That last command is likely to say: kmod-nvidia
If not, then adapt the following:

Code: Select all

yum install kmod-nvidia
systemctl reboot

Re: Windows Boot Manager on /dev/sda2 does not appear in grub

Windows is installed in UEFI mode. Centos is in legacy mode. Why? If you do load GRUB (and potentially CentOS) in legacy mode, how could that GRUB load anything in UEFI mode? You can't load EFI OS in legacy mode. You can't load legacy OS in UEFI mode. The realistic options are: * Have both OS in sa...

Re: Compatible PCI video card

The thing with PSU is that if it is too weak, then there can be problems. 350W should be plenty for the integrated graphics and sufficient for several low to mid-range discrete card models. However, PSU could become weaker over time (although they usually just fail totally). I've used NVidia cards w...
