[03:51] <fishcooker> i have server that doesn't install xorg.. i want to disable input devices; mouse and keyboard.. what should i do?
[11:00] <LeMike> thanks TJ- for your help in creating makefile yesterday. got it now and almost understood it ;)
[20:04] <hxm> i dont get how spf works at all, in this case "v=spf1 ip4:192.168.0.1/16 -all" it accepts that range of ips, but what is that ip, of the server which sends the mail or the client who connects to the server?
[20:24] <TJ-> hxm "SENDER" policy framework. The SPF record says that for this domain, these are the approved senders
[20:30] <tomreyn> is debootstrap no longer a recommended means of installation?
[20:31] <tomreyn> is there another method which you can use without serial console?
[20:31] <tomreyn> (nor KVM)
[20:32] <tomreyn> i'm looking at https://wiki.ubuntu.com/DebootstrapChroot but it seems kind of dated
[20:37] <TJ-> tomreyn: I use it almost daily
[20:37] <tomreyn> alright :)
[20:39] <hxm> TJ-: thanks
[21:09] <joshu> in /boot/grub/grub.conf I don't understand the two console parameters, e.g. ` console=ttyS0,9600 console=tty0`
[21:10] <joshu> I'm trying to create my own AMI for Amazon, so I'm trying to understand the grub settings.
[21:11] <stgraber> joshu: that tells the kernel to ouput its console messages to both the first tty as is the case by default (tty0) and to the first serial device with a speed of 9600bauds
[21:12] <stgraber> I suspect console=tty0 is probably irrelevant on cloud hosting, console=ttyS0,9600 may be how the hypervisor gets to show you boot messages though (not familiar with amazon, but I suspect they have a way to get kernel boot messages from an instance, in which case, that's how they'd do it)
[21:12] <joshu> stgraber thank you for explaining. I'm seeing different configs on different public AMIs. For instance on Amazon's own Linux AMI they have only `console=ttyS0`.
[21:13] <joshu> some other AMI use hvc0
[21:14] <stgraber> console=ttyS0 may be an equivalent of console=ttyS0,9600, assuming their kernel defaults to 9600bauds (which I think is part of the kernel build time config)
[21:14] <stgraber> same goes with hvc0, recent kernel will usually show serial devices from an hypervisor as hvc0, while older ones may not know how to detect those and instead use the generic ttyS0
[21:16] <joshu> If Amazon uses ttyS0 should I trust they are doing what's most appropriate for their platform and do the same?
[21:18] <stgraber> no
[21:18] <stgraber> it entirely depends on what kernel and kernel config you are using
[21:18] <joshu> Ok I think I understand
[21:19] <stgraber> if you use the same kernel they are, then yes, but if you use a very recent kernel, chances are that it'll be hvc0 instead. Same goes for the speed, it's probably best for you to always hardcode it to 9600 to avoid your kernel's config to potentially write faster than that
[21:24] <joshu> stgraber You've been really helpfull! I made some changes and now I see all the boot messages! :D
[21:25] <stgraber> cool, glad it helped
