weechat setup

November 16, 2018 — ~ben

so you decided to switch from irssi to weechat?

what options do you need to set? what plugins? what scripts?

i'll go over some of the most essential of these, and share my full configs.


november 13 post mortem

November 13, 2018 — ~ben

we had something of an outage on november 13, 2018 on

i awoke, not suspecting anything to be amiss. as soon as i logged in to check my email and irc mentions, it became clear. was at the least inaccessible, and at the worst, down completely. according the message in my inbox, there hade been an attempted "attack" from my IP.


no more google

August 14, 2018 — ~ben

not sure if this is appropriately tagged, but i didn't feel like making a new one.

i figured i should probably get some notes down about moving off google.

to start, i'll get a list of the things i was able to easily replace:

i'm still using:

  • gplay music/youtube
  • google maps (open streetmap isn't good enough to replace it)
  • google photos - but this is going to be replaced long-term with syncthing

dns shenanigans post-mortem

August 14, 2018 — ~ben

let's start by saying i probably should have done a bit more research before diving head-first into this endeavor.

i've been thinking about transferring my domains off google domains for some time now, as part of my personal goal to self host and limit my dependence on google and other large third-party monstrosities. along that line, i asked for registrar recommendations. ~tomasino responded with namesilo. i found that they had $3.99 registrations for .team and .zone domains, which is 1/10th the cost of the $40 registration on google domains.

i started out by getting the list of domains from the google console. 2 or 3 of them had been registered within the last 60 days, so i wasn't able to transfer those just yet. i grabbed all the domain unlock codes and dropped them into namesilo. i failed to realize that the dns panel on google domains would disappear as soon as it went through, but more importantly that the nameservers would be left pointing to the old defunct google domains ones.

i updated the nameservers as soon as i realized this error from the namesilo panel. some of the domains propagated quickly. others, not so much. was still in a state of flux between the old and new nameservers.

in a rush to get the dns problem fixed, and under recommendation from several people on irc, i decided to switch the nameservers for and to cloudflare, leaving another layer of flux for the dns to be stuck in...

of the five domains that i moved to cloudflare, 3 returned with a dnssec error, claiming that i needed to remove the DS record from that zone. d'oh!

i removed the dnssec from those affected domains, so we should be good to go as soon as it all propagates through the fickle beast that is dns.

lxd networking and additional IPs

July 26, 2018 — ~ben

now that is on a fancy-shmancy new dedi server, i've tried to get a secondary IP address assigned to a lxd container (which i plan to use for my personal stuff). lxd shows that the secondary IP is being picked up by that container, but i'm still seeing the host machine's IP as the external address.

i'm not sure how i'll need to configure the network settings on the host machine (now that we're running ubuntu 18.04 and it uses netplan for configs and not /etc/network/interfaces). another confusing thing is that the main config in /etc/netplan says that the network config is handled by systemd-networkd...

at least i have through the end of the year when my current vps runs out to get this up and running.

ping me on irc or email if you have experience with this.

July 22, 2018 — ~ben

finally got around to updating my dotfiles to use gnu stow. i adapted ~tomasino's makefile for use with the configs that i'm keeping with it.

now i just need to figure out why my ssh config doesn't copy/symlink my config to ~/.ssh when it already exists.
