Since I’m managing server and web service since almost 20years now, i’m pretty good to read and execute tutorial I found online execpt at online.net. Most of them seams to be wrote in another era and not respond to what I use.
It’s seems online.net and scaleway put a lot of restriction on different products for different reason and tutos / how to don’t mention these or take care of these.
Such as example :
IPv6: apparently you could have as you which illimited subnet; but for me, after one /56 it’s done, I can’t make more than one.
Another example but for Scaleway;
I’m able to build a Nethserver based on CentOS on a VC1x server
but unable to make it work on a C2x
for some reason which I can’t control some parameter on the kernel are different and shorewall won’t start on C2x server which works fine on a VC1x
It seams default installation have a lack of professionalism
aka why I can’t make my own partition scheme on proxmox and it result of a one big chunk partition which is not optimum for proxmox who recommend using thin LVM.
So now I’m jiggling with IPFailover
which the tutorial say you’re netmask will be 255.255.255.255;
which I’m sorry but that means /32 aka you’re gateway need to be yourself
So I try different variable for the netmask because also in the console they said
ho ho we furnish a unique gateway for every IPFailover which is : 188.8.131.52
which will make more sense anyway then using a the gateway of your main IP
because if you use the gateway of your main IP it means you need to touch you configuration so you have more potential of fails while you switch your IPFailover from server to server which is all the purpose of an IPFailover, to limited the reconfiguration…
Nous fournissions une nouvelle IP unique que vous pouvez utiliser comme passerelle par défaut dans chacune de vos machines virtuelles, peu importe le serveur host ou le datacenter: 184.108.40.206
So anyway just to make a remember for everyone; a gateway is like a polyglog who’s able to speak different network (language) and network are define by their subnet. aka if my network is 220.127.116.11/24 and I want to talk with 18.104.22.168/24 my gateway need to know both network (language).
So to make my IPFailover work with this gateway a netmask 255.255.255.255 make no sense, even 255.255.0.0 or 255.0.0.0 because my IPFailover is in the network 22.214.171.124/idontknow. Even to speak with my main gateway of my main IP which is mention in the official tutorial it still make no sense because
126.96.36.199 and 188.8.131.52/24 are far the be the same IP such as mention the subnet and with any mask as mentioned : 255.255.255.255, 255.255.0.0 or even 255.0.0.0
I’ll stop here for now
But for now Online.net sound synonym of nosense for me.
