[1164.48 --> 1168.68] Well, I was actually talking with Wendell about this the other night because he did a video on Pi KVM |
[1168.68 --> 1170.44] and I sort of messaged him afterwards and said, |
[1170.52 --> 1178.58] you know what would be really great is if I could take that single Pi 4 that I've got acting as a KVM unit |
[1178.58 --> 1182.58] and control three or four systems with it. |
[1182.58 --> 1186.62] I'm like, well, surely this should be possible with an HDMI switcher. |
[1187.04 --> 1190.82] But I tried a couple in the past and they need you to actually be physically present |
[1190.82 --> 1195.18] to push the button on the front of the damn thing to change the input from system one, |
[1195.34 --> 1197.12] system two, three, four, whatever. |
[1198.00 --> 1201.24] But the really nice thing about the unit that I've put in the show notes, |
[1201.50 --> 1205.10] it's a four port HDMI switch. |
[1205.24 --> 1206.00] It was about $60. |
[1206.00 --> 1211.28] And this thing lets you use a keyboard shortcut to change inputs. |
[1211.40 --> 1214.42] So I just press control, control, one, control, control, two, |
[1214.74 --> 1218.12] and that changes the input on the KVM switch. |
[1218.42 --> 1222.44] So how I've got it wired up is the HDMI goes from the server |
[1222.44 --> 1228.28] out into the input of input one on the switch. |
[1228.28 --> 1236.96] And then it comes from the switch output port into the capture port on the Raspberry Pi 4 through the CSI bridge. |
[1237.34 --> 1239.74] Now, I've written a blog post about this, of course, |
[1239.88 --> 1242.74] because that's what I seem to spend my spare time doing. |
[1243.16 --> 1245.50] And I put a link to it in the show notes with a little diagram |
[1245.50 --> 1249.46] in case that is a little confusing to follow by my talking. |
[1249.64 --> 1252.90] But it takes about five minutes to wire up and put together. |
[1253.96 --> 1255.82] And yeah, it just works, Morgan. |
[1255.82 --> 1257.04] That's the really cool thing. |
[1257.14 --> 1263.14] I can now switch between my server and my other server and my Raspberry Pi 3 that's doing DNS. |
[1263.62 --> 1266.30] And they all just appear in the browser. |
[1266.54 --> 1267.56] It's like magic. |
[1268.10 --> 1269.26] Does it have the ability to record? |
[1269.66 --> 1270.62] Can you record the output? |
[1271.00 --> 1272.08] I don't think it does. |
[1272.20 --> 1273.56] You can record macros. |
[1273.62 --> 1277.44] So you can record different keyboard sequences and mouse sequences and that kind of thing. |
[1277.66 --> 1280.16] But I don't think it will let you record the actual stream. |
[1280.86 --> 1283.60] Although it's a WebRTC based system. |
[1283.60 --> 1289.58] So I would wonder if there's some kind of a stream that we could hook into with VLC or something and maybe do it like that. |
[1289.90 --> 1294.14] If you know the answer to that, again, write in and let us know at selfhosted.show slash contact. |
[1295.26 --> 1299.18] Now, you're much more of a sysadmin than I am, I would say. |
[1299.24 --> 1304.82] You've got a bit of a background working in all sorts of different places, cruise ships and hospitals and all sorts of places, right? |
[1304.82 --> 1311.24] So you've probably run into email gateway issues when servers are trying to notify you that they've failed. |
[1311.82 --> 1314.68] That's always been one of the fun parts about working in a data center. |
[1315.22 --> 1318.10] Most of my employment has been with Exchange. |
[1318.26 --> 1321.24] And you always run into these systems that just need an open relay. |
[1322.06 --> 1325.12] As anybody knows, open relays are a little bit dangerous in the world. |
[1325.12 --> 1332.90] So you're always looking for a good solution for, you know, an SMTP gateway that isn't expensive. |
[1333.30 --> 1338.30] Or you can do what most people do and just copy their Gmail password around onto various boxes and have it connect that way. |
[1338.38 --> 1340.26] I mean, what's the worst that can happen? |
[1340.58 --> 1342.06] Yeah, when you're working from your home. |
[1342.18 --> 1344.62] But, you know, what happens when you're working in a data center? |
[1345.12 --> 1346.64] You're probably going to get that blocked. |
[1346.92 --> 1347.74] Probably, yeah. |
[1347.74 --> 1350.76] So I have an app pick for you that might tickle your fancy. |
[1350.90 --> 1352.10] This one's called MailRise. |
[1352.28 --> 1355.44] And this is an SMTP gateway for notifications. |
[1355.80 --> 1359.40] Essentially, it plugs into an app we've mentioned before called AppRise. |
[1359.86 --> 1367.70] So this MailRise application kind of sits in the middle, listening for emails, you know, syslog emails, whatever it might be. |
[1367.78 --> 1370.40] Failures coming in from various different system services. |
[1370.92 --> 1376.22] And when it receives the email, it reacts to that and then connects to AppRise. |
[1376.22 --> 1382.06] So you can talk to any of the 60 plus notification services that AppRise supports. |
[1382.30 --> 1385.68] So, you know, Telegram, Slack, Discord, you name it. |
[1386.44 --> 1397.36] For those of you who are new to the show or possibly missed that episode, AppRise is a great tool that allows you to send notifications to almost all the most popular notification services today. |
[1397.86 --> 1403.06] Think Telegram, Discord, Slack, you know, Reddit for those people who are really cool. |
[1403.18 --> 1405.68] You know, it's a one notification library to rule them all. |
[1406.22 --> 1413.46] And what's great is, is the tool MailRise, as Alex said, sits in front of that and is an SMTP gateway. |
[1413.88 --> 1419.80] So there's a lot of applications that really don't have the ability to have that newer feature. |
[1420.52 --> 1425.68] And MailRise gives you that by allowing you to send emails to the SMTP gateway and then you can send it off. |
[1425.68 --> 1434.86] So when your laundry is done, you can send an email and post it on Reddit to let everybody know I now have clean clothes. |
[1435.64 --> 1436.60] Hooray for that. |
[1436.92 --> 1438.40] And that, you know, we live in the future. |
[1438.76 --> 1442.90] We can monitor Morgan's laundry schedule via Reddit. |
[1442.90 --> 1451.04] And speaking of the cloud, CloudFree.shop has some exciting news this week. |
[1451.26 --> 1454.58] They have released their version 2 smart plugs. |
[1454.70 --> 1455.46] So these are really cool. |
[1455.56 --> 1457.56] They've got energy monitoring built right in. |
[1458.16 --> 1461.10] And of course, they run TASMOTOR out of the box. |
[1461.10 --> 1467.36] And, you know, the best thing about the company, it's a small family owned business run by one of our very own listeners. |
[1467.60 --> 1472.26] Now you can go to CloudFree.shop and use the coupon code self-hosted so that they know that we sent you. |
[1472.82 --> 1475.72] And you also get a dollar off per plug as well. |
[1476.08 --> 1479.16] So that's CloudFree.shop with the coupon code self-hosted. |
[1479.16 --> 1481.98] Mike writes to us, |
[1481.98 --> 1483.72] Hey guys, love the show. |
[1484.12 --> 1485.82] I'm a longtime Linux user and administrator. |
[1486.26 --> 1489.46] But I have to admit, I've fallen a little behind on the whole container craze. |
[1489.86 --> 1490.86] That's understandable, Mike. |
[1491.36 --> 1492.96] I'm very comfortable with VMs. |
[1493.22 --> 1494.84] They always made logical sense to me. |
[1495.30 --> 1501.40] You have a virtual disk image, probably something with some metadata in it, and you get to run as a full-fledged system. |
[1501.96 --> 1507.98] Something about the whole Docker runs X and it just magically happens without specifying any parameters |
[1507.98 --> 1509.46] just struck me as creepy. |
[1510.44 --> 1513.82] Regardless, I've used them a little bit inside of Firewall for LAN services, |
[1514.16 --> 1517.08] but I'm wondering if there are best practices that either of you use. |
[1517.44 --> 1522.42] For instance, when you're running multiple containers with persistence, where would you put the compose file? |
[1522.84 --> 1525.96] Do you have any tips for organizing container volumes on CFS? |
[1526.56 --> 1528.72] I've looked around and I haven't found any good articles. |
[1528.72 --> 1534.54] Just lots of run Docker compose up and magic happens, which is disconcerting in a production environment to me. |
[1534.54 --> 1538.24] That's the beautiful thing of Docker is it is just magic. |
[1538.76 --> 1541.44] And for some people, that's exactly what they need. |
[1541.80 --> 1550.72] You know, for your average person running an Unraid box or a small Raspberry Pi who's not working in this stuff day-to-day, |
[1550.72 --> 1556.82] being able to do Docker run Plex or whatever it is without having to juggle half a dozen Bash scripts |
[1556.82 --> 1560.12] and eight different versions of Java and all this kind of crap. |
[1561.10 --> 1563.62] That's exactly where Docker is going to win. |
