Bob

@allquixotic Eh, "can't think of a project" is kinda my default state

goes along well with "abandoned yet another project" :D

Journeyman Geek

@Bob heh. THATS WHY YOU HAVE FRIENDS LIKE ME ;p

least for the former XD

allquixotic

@Bob maybe so, but all it takes is for someone else to spend 5 minutes talking to you about a problem they're having, and you're off coding... the motivation boils over and you're in your IDE in minutes

bwDraco

I think I need to remember that I have to get a full-time job, and to get a job, I need certain skills. It's not pointless. Docker is a highly desirable skill in the job market.

Journeyman Geek

@bwDraco see, that's not how I think.

I'd go "hey, maybe I should run bitwarden. Damn it, it needs docker"

then one afternoon, I go beat it into working cause I'm bored. Now I know docker.

allquixotic

06:02

@JourneymanGeek yeah, that's the way I learned most things, although I've been gradually transitioning into the way bwDraco just said for certain technologies

bwDraco

Hmm... so you're doing this because you're trying to run the bitwarden server?

Journeyman Geek

or with this server "hm, yanno? Running in a KVM VM got boring" then "ehhh, ngnix is something I've been putting off"

allquixotic

@Bob abandoning a project isn't such a terrible thing if you learn something in the effort, though... completion isn't always the goal, or anyway, not the only goal

Journeyman Geek

@bwDraco I'm doing this case erm... it makes me happy?

It makes my life better in some small way?

allquixotic

I've only completed, like, a small handful of my projects to any level of real utility: rbpitch, tribblify, yasdown, kynnaugh-cc... and that's about it

bwDraco

06:04

...and this reminds me of that secure-erase script again. I was playing around with a portable SSD being used for caching (because of netbook SSD endurance concerns) and had to secure-erase it repeatedly.

It's those silly little things that get me to write code/play with new technologies/etc.

Bob

@allquixotic true... I really should get back to trickleedit sometime though

Q: Using a portable SSD to divert or reduce writes to system storage on a low-memory Windows 10 laptop

TL;DR Is there a way to use a USB 3.0 portable SSD to reduce writing to an inexpensive laptop's low-capacity eMMC storage? The system has only 2 GB of RAM, so paging is often unavoidable, resulting in more writes than would otherwise occur to the already fragile TLC NAND. Background This que...

Bob

@bwDraco ya, that's how it usually goes

maybe next time @JourneymanGeek has a problem you can write a powershell script for him :D

Journeyman Geek

;p

bwDraco

A small script (just a few lines of code) turned into a nontrivial program, large enough to require a license header.

Bob

^ that was a docker attempt :P

Journeyman Geek

;p

allquixotic

lately I've been on my high horse about TDD and learning Docker, Jenkins, Rust, and yet more Selenium as time allows

much of that work-inspired

Bob

@allquixotic how's Rust going?

it's always looked interesting

(also the Planet Mozilla feed is usually at least half about Rust...)

allquixotic

06:14

@Bob community is weird, language looks alien (to my C/Java/C++/C#/Ruby eyes, anyway), perf is very much in the vein of C (it puts Go, Java and Ruby to shame), interop with non-Rust code is fine for Rust -> C but weird for most other languages

bwDraco

So... I guess I will be spinning up a local VM to run Docker. Usual familiar openSUSE environment, will be given plenty of vDisk space to allow for expansion.

allquixotic

it's more stable nowadays, in terms of actually working, although bugs aplenty is the prevailing sentiment

bwDraco

The great thing about virtualization is that because everything is software-defined (wink wink), you can resize disks, move the vDisks to another physical drive, assign variable amounts of compute/memory/etc., without too much effort.

allquixotic

a lot of my struggles come down to not being familiar with conventions, core APIs, etc. because a lot of it is a departure from the runtimes I know the best (C/GLib, JVM, .NET and Ruby)

Journeyman Geek

@bwDraco do things, break things, complain ;)

then break things till nothing else is to break. Then fix things.

bwDraco

06:18

In high school, I installed VirtualBox into quite a few of the school machines and played with different OSes simply because I was curious about the world beyond Windows.

@JourneymanGeek That's what VM snapshots are for :p

allquixotic

Journeyman Geek

@bwDraco VM snapshots are for when it works

bwDraco

Snapshots give total freedom to experiment with different stuff. If it breaks, you just revert.

allquixotic

@JourneymanGeek can't tell you how many times I forgot about snapshots, manage to break boot or someting really low level that I CBA to fix in a Linux VM, and have to re-do my VM

Journeyman Geek

@allquixotic hah

allquixotic

06:20

even happens for platforms I know like the back of my hand like Ubuntu LTS... I could probably fix it, but not worth the effort for a VM

bwDraco

I was playing with Linux from Scratch a while back... wound up abandoning that, too.

Journeyman Geek

@allquixotic my home linux box occationally refuses to boot after an upgrade

bwDraco

Used to run an old desktop dedicated to Linux. That machine has been dismantled and the role of the dedicated Linux system is assigned to the oldest of my laptops.

Bob

@allquixotic There's some irony in Rust having lots of bugs :P

Of all languages...

bwDraco

Well, AIUI Docker is pretty low-risk. It's kinda hard to mess up a system running Docker.

@allquixotic Same for me, with my most familiar Linux distro (openSUSE).

Journeyman Geek

06:38

@allquixotic tbh, for stuff like my server, I try to have documentation good enough that I can set it up half dead ;p

bwDraco

Bleh. archived my LFS VM files.

bwDraco

So... setting up the VM. 4 GB memory, 4 vCPUs, 16 GB storage (easily expanded), plus 2 GB for swap (just in case - not really necessary because the host has 32 GB of RAM but Linux systems may not like having no swap space at all)

Journeyman Geek

@Bob someone mentioned tamil ;p

bwDraco

07:29

...installing the guest OS.

...wait a sec. I didn't know YaST had a module for Docker.

(but I'll primarily be using the command-line tools)

In other news... the government has shut down again.

though it appears they are working on a full-fledged appropriations bill this time around and not a continuing resolution.

@Ramhound I wasn't talking about SLI or DX12 multigpu. I was talking sticking in more video cards for more outputs,

Burgi

@djsmiley2k if the sea isn't too rough

Journeyman Geek

@djsmiley2k you could, if you didn't hit bad weather ;p

I was slightly sad they didn't do hovercraft any more.

Burgi

they use seacats now which are faster and can carry more stuff

djsmiley2k

I was on a seacat in gale force winds before

That wasn't fun

Also need WiFi

Ramhound

10:16

So Windows 8+ allows you to use different GPUs for the displays?

I know WDM was updated significantly between Windows 7 and Windows 8 and it continued to receive updates associated with multiple displays in Windows 10 but wasn’t aware of that

Burgi

ugh this deployment isn't going to plan

Q: How do I set up a static route between twi

Asus +---------+ +--------------+ |Internet +---------------------------------->+ Primary router | | | 192.168.1.1 +------->Dumb Switch +---------+ ...

networking router

there we are

djsmiley2k

@JourneymanGeek did you turn the nat off

Journeyman Geek

@djsmiley2k erm no

why would I?

I'm not doing a router/AP set up

I'm essentially doing double nat, then setting a static route between them

djsmiley2k

13:26

Well.... You'll hide the 2nd routers traffic

As the up on the pic interface

Journeyman Geek

13:44

@Bob @djsmiley2k actually....

Bob

13:57

@JourneymanGeek "between twi"

allquixotic

what's twi?

Bob

@JourneymanGeek why did you specify 192.168.1.142 as the gateway?

allquixotic

@Bi

Journeyman Geek

@Bob its the IP address of router 2 on the main network

Bob

@JourneymanGeek but... your diagram has it at 192.168.1.100

Journeyman Geek

13:59

eep

diagram is wrong

allquixotic

is there any particular reason you don't just make one of the routers also a dumb switch, so everything can be on the same broadcast domain / subnet?

Journeyman Geek

@allquixotic err... 1) I don't get how static routes work, so Its a chance to learn

2) ... eventual reasons.

(that was how I was running it before, and I know how to do that)

allquixotic

why does your secondary router have an IP that isn't even on its subnet?

your secondary router's IP should be within the range 10.0.0.0/25

Journeyman Geek

@allquixotic in its own network its 10.0.0.1

allquixotic

or does it have two separate NICs with different IPs.... ahhhh

Journeyman Geek

14:04

@allquixotic I'm currently double natted?

......

allquixotic

ok, so it has a NIC port that is on the 192.168.1.0/24 network, and one that's on 10.0.0.0/25

Journeyman Geek

erm. Ya

allquixotic

because of the layer 2 bridge between the routers, you should be able to add the static routes to client computers, actually

just add a route to the routing table of each computer that sends all traffic to the foreign subnet to its gateway

Journeyman Geek

ehh. I could but erm.

Reasons? ;p

(I basically want this hairbrained setup to practice a few things)

NotAdmin Dave

GM all.

allquixotic

14:07

well, the only way to do it from the router that I can think of would be to have DHCP on the main router automatically push the static route to its clients on DHCP renewal

Journeyman Geek

0_0

allquixotic

if that's what the static routes do, then that'd be fine

however, the gateway should be 10.0.0.1

Bob

@allquixotic naw

Journeyman Geek

how would the main router know where 10.0.0.1 is?

Bob

static route on the router means clients send packets to default gateway (router) which forwards according to the static routes

still afk-ish for a few mins

Journeyman Geek

14:09

@Bob no rush ;p

allquixotic

@JourneymanGeek it knows because when you set up the layer 2 bridge via the "dumb switch", ARP is updated to include a MAC address for the foreign router, which is directly reachable with "zero hops" (no layer 3 routing)

what @Bob just said suggests a static route like that should work if you want to do layer 3 routing instead

but you should be able to just ping 10.0.0.1 from a client on the 192 network without any static routes

Journeyman Geek

0_0

lemme remove the routes and try

allquixotic

to get to clients behind the 10.x network you'd have to route through the 10.x gateway at layer 3, but you should be able to reach the gateway itself in zero layer 3 hops (well, one -- the 192 router counts as a hop)

FML Cat

@allquixotic Mmm Xeon-D has been long overdue for an update

Me likey

Wonder if it'll mean better cheap OVH servers

allquixotic

that's what ethernet bridging (or MAC bridging in general, including wifi APs) does: it allows the two gateway devices to talk to each other without any layer 3 routing set up between them

Address Resolution Protocol

The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address associated with a given IPv4 address, a critical function in the Internet protocol suite. ARP was defined in 1982 by RFC 826, which is Internet Standard STD 37. ARP is used for mapping a network address such as an IPv4 address, to a physical address, such as a MAC address. ARP has been implemented with many combinations of network and data link layer technologies, such as IPv4, Chaosnet, DECnet and Xerox PARC Universal Packet (PUP) using IEEE 802 standards, FDDI, X.25, Frame Relay a...

allquixotic

shouldiblamecaching.com

Bob

@allquixotic no; that'd only work if the router listens to 10.0.0.1 from the WAN interface

I actually have the firewalls configured on my ER-X to explicitly block that

speaking of, @JourneymanGeek, check the VLAN config on the second router. and check the firewall rules.

Journeyman Geek

14:24

hm?

Bob

@JourneymanGeek uh, yea, turn off NAT

Journeyman Geek

0_0

where? there's a nat loopback and a nat target option

nat target is snat or masqurade

Bob

@JourneymanGeek apparently "Advanced" => "Miscellaneous" => change it from "Gateway" to "Router"

Journeyman Geek

that's under routing

Bob

@JourneymanGeek what's under what?

FML Cat

allquixotic

@FMLCat that's what I said like an hour ago, but he doesn't want to do that

Bob

@FMLCat for fun? :P

allquixotic

31 mins ago, by allquixotic

is there any particular reason you don't just make one of the routers also a dumb switch, so everything can be on the same broadcast domain / subnet?

Journeyman Geek

Bob

@JourneymanGeek then change it the other way

FML Cat

14:32

@allquixotic great minds think alike!

Journeyman Geek

@Bob tried both options

FML Cat

@Bob i don't route for fun, I spanning tree Bridge and mesh for fun

Bob

hmm. apparently Gateway is supposed to be the one that does NAT

@FMLCat you're too advanced for this room :P

we're struggling with basic routing here :D

Journeyman Geek

@Bob which is almost reassuring

@allquixotic I actually want to get this working just to get it to work ._.

Bob

@JourneymanGeek Wait. ... why are you sending the 192.168.1.0/24 packets into the 192.168.1.1 gateway?

Journeyman Geek

14:34

Yes, its a bit of an XY problem

FML Cat

Routing is so 1990's ~~chic~~ geek

Bob

they're supposed to be on the local net on the wan side of second router

Journeyman Geek

where?

Bob

@JourneymanGeek second router should not have that static route

Journeyman Geek

oh

0_0

added it while testing

Bob

14:36

all you should have is second router in routing without NAT mode, and first router with a static route from its gateway into the second router

Journeyman Geek
