Re: How to confirm power chords and power supplies are plugged in

The best way would be to access the IPMI (iDRAC, iLO,etc) over ssh and obtain the necessary information from there.
Usually IPMI supports e-mail & snmp traps - so you should be able to monitor it properly.

From Linux perspective - if there is no info from the HW , you cannot obtain such info.

Re: samba-vfs-glusterfs missing in CentOS 8

Re: TCP OFFLOADING --- INCORRECT CHECKSUM

I guess some device on the path (most probably a switch) doesn't support Frame control (IEEE 802.3x) - for example being disabled from the configuration.

Re: They are trying to hack me again

I use port knocking in order to respond to icmp or allow ssh.

No icmp echo reply - no ssh attempts.

Re: Custom Kernel want to secure boot with custom private key

You need to compile and sign your new kernel. Then, you have to find a way to make your signature trusted.

I think that you might find more info here .

Re: 2 nic 2 gateway

Actually it's possible , for example this one sounds plausible , yet it's impractical. Another way is to have it properly defined and set the static routes necessary. I think I saw somewhere a blog mentioning multiple routing tables that could allow that. Yet, I don't see any reason to create such a...

Re: Why is it so slow to log in after changing the root username and waiting 26 seconds

Just don't rename root.
Just set in sshd' config 'PermitRootLogin no' and you will be OK.
The defaults for sshd are prety good.
