Re: Help on CentOS 7.6 MAC & interface swap
Unfortunately, since EL7 came out. Device enumeration order from the hardware isn't guaranteed or expected to be the same every boot, and systemd's udev doesn't do the "rename" shuffle that old EL6 and earlier udev used to do. ethX naming appears to work fine... most of the time. However, every so o...

Re: Help on CentOS 7.6 MAC & interface swap
Forcing "ethX" names for interfaces isn't possible anymore.
Either use the systemd/biosdevname naming, or call your interfaces a non-kernel name like "netX" or "prod" and "backup".

Re: Supposed security vulnerabilities with openssh
The vulnerability is about X11 Forwarding over SSH.
Disable X forwarding and the unsecure codepath can never be entered.

Re: modprobe USB devices except keyboards and mice
A udev rule similar to this should match USB storage only:
Code: Select all
ACTION=="add", KERNEL=="sd?", SUBSYSTEM=="block", ENV{ID_BUS}=="usb", RUN="/bin/true"

Re: Networking namespace
You don't need either of those packages, that's a very old kernel and the latest iproute in 6.7 has netns support, I logged the bug to add it.
I would suggest trying with the official packages, not those old OpenStack ones.

Re: fail_over_mac with bonded vlan interface not working
The VLAN device's MAC remains the same, the bond's new MAC is added to the VLAN's list of accepted MAC addresses.
You cannot see the list of MACs, it is internal to kernelspace.
So even though it looks like it's broken, it actually does work in the latest kernels.

Re: CentOS/Kernel 3.18/Thunderbolt2
Thunderbolt should be working as of 3.17 and the Arch wiki on Macbooks says 3.18.1 is working well. However it looks like you would need to recompile, as the ELRepo kernel is built without Thunderbolt support: # egrep -i thun /boot/config-3.18.2-1.el6.elrepo.x86_64 # CONFIG_THUNDERBOLT is not set I ...
