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.

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...

For partitioning - anything modern (bad example is fdisk from CentOS 7.0) is enough. I ...
