<p>i've recently been working on setting up <a href="https://drone.tildegit.org">drone ci</a>
|
|
on the tilde.team machine. however, there's been something strange going on

with the networking on there.</p>

<p>after the <a href="november-13-post-mortem.html">fiasco</a> earlier this week, i've been taking steps to minimize
|
|
the impact if tilde.team were to go down. it's still a large spof (single-point-of-failure), but i'm reasonably certain that at least the irc net will remain up and functional in the event of another outage. </p>

<p>we had something of an outage on november 13, 2018 on tilde.team. </p>
|
|
|
|
<p>i awoke, not suspecting anything to be amiss. as soon as i logged in to check my email and irc mentions, it became clear.</p>
|
|
|
|
<p>tilde.team 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.</p>

|
<p>let's start by saying i probably should have done a bit more research before
|
|
diving head-first into this endeavor.</p>
|
|
|
|
<p>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. <a href="https://tomasino.tilde.team">~tomasino</a> responded
|
|
with <a href="https://namesilo.com">namesilo</a>. 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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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. tilde.team
|
|
was still in a state of flux between the old and new nameservers.</p>
|
|
|
|
<p>in a rush to get the dns problem fixed, and under recommendation from several
|
|
people on irc, i decided to switch the nameservers for tilde.team and tilde.zone
|
|
to cloudflare, leaving another layer of flux for the dns to be stuck in...</p>
|
|
|
|
<p>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!</p>
|
|
|
|
<p>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.</p>

|
|
<p>now that tilde.team 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.</p>
|
|
|
|
<p>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...</p>
|
|
|
|
<p>at least i have through the end of the year when my current vps runs out to get this up and running.</p>
|
|
|
|
<p>ping me on <a href="https://tilde.chat">irc</a> or <a href="mailto:ben@tilde.team">email</a> if you have experience with this.</p>

<p>hey hi hello!</p>
|
|
|
|
<p>it seems that i haven't written anything on my blog in quite a while...</p>
|
|
|
|
<p>time to fix that! i've been quite busy in the last month or so with a lot of new ideas an energy for tilde.team.</p>
|
|
|
|
<p>after rediscovering my account on tilde.town, i hopped in the irc there and my enthusiasm translated into a couple new members over here on the ~team.</p>
|
|
|
|
<p>our irc has been somewhat more active recently which is awesome:)</p>
|
|
|
|
<p>some of the new updates in the last month:</p>
|
|
|
|
<ul>
|
|
<li><a href="https://git.tilde.team">tildegit (our own gitea instance)</a></li>
|
|
<li><a href="https://mail.tilde.team">tildemail</a> with postfix and dovecot for smtp/imap as well as local command line mail in mutt and alpine</li>
|
|
<li><a href="https://git.tildeverse.org/team/tilde-launcher"><code>tilde</code></a> user script wrapper with submission and approval flows</li>
|
|
<li><a href="https://tilde.team/wiki/?page=ssh">password auth disabled</a></li>
|
|
</ul>
|
|
|
|
<p>i'd like to make use of our new mailserver, so shoot me some <a href="mailto:ben@tilde.team">mail</a>.
|
|
i never get enough personal mail. it's all still privacy policy update notices. :(</p>
|
|
|
|
<p>see you soon!</p>
