comment Using anacron in cronie on Gentoo - Doesn't run?
Yeah, that is effectively how to fix it, but I am more curious about what the intention was. Really, you don't even need cron.hourly to run, as it will get run when anacron eventually runs. Just running anacron every few minutes (if it isn't running) would do it. I guess they just didn't finish implementing it.

(note that erroneous route advertisements are pretty common, but they are almost always screwups, rather than malicious)

A server cannot ordinarily broadcast its IP and have the network expect to listen. This is done at a router level, and the routers are owned by ISPs that have agreements in place to trust each others route advertisement. It is certainly possible to inject false routes with the right level of access. But this can be solved by ignoring the source of the advertisements, nothing needs to be turned off.

An individual IP address is generally not owned by a company, they operate at a block level. Consider the scenario where you have a datacenter in NY and one in Egypt. If the NY one fails, you want everything to route to Egypt. This is done with Autonomous Systems and BGP. The owner of the block effectively tells the internet how the block should be routed, and the internet learns the path. If something changes, then the new path is learnt. You couldn't have any redundancy if you had to go and tell a central authority, this has to happen in seconds.

comment How can I get rid of the double NAT in this network?
Hi, it should be LAN to LAN. So you have it right now. Are your devices getting ip addresses?

Ok, what you need to do is turn off DHCP on the router, and give it an address in the same range that the WAN port gets when it connects to the modem, then connect the modem to the LAN port, not the WAN port. This will give you a single network across wifi and lan and modem. Then change the DHCP scope on the modem to exclude the IP you gave the router. Every one will get their IP address from the modem, including wifi people.

Do you know what function the router is providing? If the is layer 3 connectivity between the modem and router, which there must be for the router to NAT, then the modem is also a router. Which means you should be able to just remove the router and connect the switches to the modem.

What is the connectivity between the modem and router? There shouldn't be any need to route between these two devices, and so no need for double NAT.

comment how do I grep only the user created profiles among all users in linux ?
Linux can be set in any way the administrator pleases. /home is common, but not always present. What you don't have is a clear definition of what a user is in this scenario, so it would be difficult to come up with anything that would work every single time.

Do users only have home directories maybe?

Are your users in a group, or using a UID sequence that differs from system accounts? Or otherwise do you have a way of identifying a user account vs a system one?
