1
00:00:00,000 --> 00:00:07,200
when it comes to diagnosing networking problems say you're an I.T person you're

2
00:00:05,040 --> 00:00:12,120
just at your house whatever there are lots of tools on the market except so

3
00:00:09,540 --> 00:00:17,160
many of them cost a thousand dollars or five thousand dollars or ten thousand

4
00:00:14,880 --> 00:00:21,000
dollars this one isn't specifically designed to help with Hardware problems

5
00:00:19,140 --> 00:00:25,800
but rather I guess you call it software problems configuration problems and also

6
00:00:23,580 --> 00:00:29,760
to make configuring your network faster these are the net tool i o Pro 2 and I

7
00:00:28,680 --> 00:00:36,960
think this one's called the light it's called the light I think it's the light basically it's a little dongle I guess

8
00:00:34,260 --> 00:00:40,860
since we get in here let's open this one ah

9
00:00:39,120 --> 00:00:45,719
what is this oh this is the actual thing beautiful

10
00:00:42,440 --> 00:00:48,840
there's one that's the light oh the

11
00:00:45,719 --> 00:00:50,640
green is nice look at that

12
00:00:48,840 --> 00:00:55,860
we've got a little quick start guide charger patch cable stickers I'll be

13
00:00:54,480 --> 00:01:01,620
sure to find somewhere to stick that on crooked I think the other one is going to be the same this one I opened already

14
00:00:58,920 --> 00:01:05,100
is the light I like the green though I have the pro one here I've been using it

15
00:01:03,059 --> 00:01:10,880
for a few days this looks way cooler color wise why is it the cheaper

16
00:01:07,500 --> 00:01:10,880
crappier one that looks cooler

17
00:01:11,060 --> 00:01:18,900
color matched cables that's cute wow

18
00:01:15,540 --> 00:01:19,740
we got matched stickers oh that makes

19
00:01:18,900 --> 00:01:22,820
sense wonderful noise

20
00:01:22,920 --> 00:01:29,280
it's gonna be a type c to a cable plugs in on the bottom there

21
00:01:27,360 --> 00:01:33,180
just like that to charge these things do have a battery in it which is very

22
00:01:30,780 --> 00:01:37,439
helpful you don't have to carry this thing around and ah is there a plug

23
00:01:35,340 --> 00:01:41,579
there that would make this a very stupid tool 2500 milliamp hour battery in each

24
00:01:40,200 --> 00:01:47,220
of them I played around with it for about a day the pro version and I maybe

25
00:01:44,520 --> 00:01:51,360
went down like 30 battery life so on the bottom of each of them you have a port

26
00:01:48,479 --> 00:01:55,079
for charging and then a port for USB connectivity I'm not sure what other

27
00:01:52,920 --> 00:01:59,939
stuff you can do but you can at the very least do pcap capture to a USB stick

28
00:01:57,960 --> 00:02:04,740
which is pretty helpful on the top is the Ethernet Jack that's going to plug

29
00:02:02,220 --> 00:02:08,700
into a network switch or I guess a wall jack whatever you're trying to diagnose

30
00:02:06,719 --> 00:02:12,660
or get information from yeah aside from that it's just the little LEDs on the

31
00:02:10,619 --> 00:02:17,040
front and power buttons the top is a port activity indicator the second one

32
00:02:15,000 --> 00:02:20,400
probably status of some point it's got a little like heartbeat sign which makes

33
00:02:18,900 --> 00:02:25,020
me think it tells you what's going on currently and then battery indicator I

34
00:02:23,280 --> 00:02:28,980
never used the first generation of these tools I know that this these are the

35
00:02:26,700 --> 00:02:33,060
second generation ones I don't know what the main differences are but I do know

36
00:02:31,140 --> 00:02:36,360
that these ones have both Wi-Fi and Bluetooth which is super cool when I

37
00:02:34,860 --> 00:02:40,920
plug this thing in and turn the Wi-Fi hotspot on and connected my phone it

38
00:02:38,340 --> 00:02:45,180
actually acted as an access point to give my phone internet through the cable

39
00:02:43,200 --> 00:02:50,640
that it was plugged into which is super cool what app do we got here net tool I

40
00:02:48,780 --> 00:02:53,819
think I have the pro one already yeah oh wait what

41
00:02:51,900 --> 00:02:58,620
oh Pro 2. ah so the original one must have been

42
00:02:55,980 --> 00:03:02,580
called the nettool.io and then the pro version was the net tool i o Pro and

43
00:03:00,900 --> 00:03:06,540
then there's the Pro 2 and the light which is the two ones we have today kind

44
00:03:04,739 --> 00:03:10,620
of seems like it could be one app I'm not gonna lie but I know that they're a

45
00:03:08,640 --> 00:03:15,959
relatively small company so if this makes it a lot easier then cool

46
00:03:14,280 --> 00:03:20,340
you look at that it's detected over Bluetooth and we'll check it out as soon as I tell

47
00:03:18,599 --> 00:03:23,400
you about our sponsor secret lab chairs are engineered to keep you incredibly

48
00:03:21,780 --> 00:03:27,120
comfortable for long hours at work and play their Titan Evo 2022 chair keeps

49
00:03:25,560 --> 00:03:29,940
you feeling comfortable for longer with four-way lumbar support and Ultra

50
00:03:28,739 --> 00:03:35,159
comfortable line of different seat materials and more not to mention all chairs come with a five-year extended

51
00:03:33,180 --> 00:03:37,940
warranty and a 49 day return policy so head to the link down below and check

52
00:03:36,420 --> 00:03:44,159
out secret lab today whoa so immediately it's got Lan ipv4

53
00:03:41,879 --> 00:03:49,080
IPv6 it shows us The Gateway the configured DNS servers the subnet the

54
00:03:46,260 --> 00:03:53,760
DHCP server IP shows you the domain shows you the public IP address the port

55
00:03:51,360 --> 00:03:58,620
Mac Address the host name of the switch the type of switch oh my God to be clear

56
00:03:56,760 --> 00:04:02,459
I've been using this for a few weeks just to try it out and one of the the

57
00:04:00,599 --> 00:04:06,420
most useful things is being able to just go hey someone's having weird issues

58
00:04:04,739 --> 00:04:09,360
with this port they're not getting an IP address well let's see if it maybe it's

59
00:04:07,799 --> 00:04:13,379
their device I can just walk over there plug into the port let's see if it gets

60
00:04:11,159 --> 00:04:16,739
an IP address boom it gets an IP address clearly there's something wrong with the

61
00:04:14,819 --> 00:04:20,040
device not the switch or the port it's so nice to be able to to carry this

62
00:04:18,479 --> 00:04:23,400
thing around and just plug into things let's see what else we could do of

63
00:04:21,660 --> 00:04:27,660
course the most important setting at the top dark mode oh God this is supposed to

64
00:04:25,979 --> 00:04:31,919
be one of the big selling features of the pro is the switch configurator I

65
00:04:29,820 --> 00:04:35,520
don't think it would work with this little UniFi switch because it's managed

66
00:04:33,960 --> 00:04:39,780
through ubiquity Zone interface but if you have like a Dell switch or Cisco

67
00:04:37,320 --> 00:04:44,040
switch you can go in here and configure a lot of different things the if is

68
00:04:42,479 --> 00:04:47,820
going to be whatever the command line is currently outputting as kind of your

69
00:04:46,020 --> 00:04:52,020
start so let's say that's the start you go switch underscore Port this is a

70
00:04:49,740 --> 00:04:55,139
placeholder as you can see up here is a key to import the current switchboard

71
00:04:53,639 --> 00:04:59,759
that you're plugged into now that we have a template filled that we we can go into the configuration queue oh it shows

72
00:04:58,500 --> 00:05:04,199
you what the configuration capabilities are that's really cool I really wish I

73
00:05:01,919 --> 00:05:09,180
had something to try this part with man I was trying to wrap my head around what

74
00:05:06,720 --> 00:05:13,440
this would be useful for in terms of configuring unless you just had to write

75
00:05:11,160 --> 00:05:16,860
out like a whole script even if you're using like a touch interface it's still

76
00:05:15,419 --> 00:05:20,160
kind of annoying but it all makes sense now say you're in an office building and

77
00:05:18,540 --> 00:05:25,740
you're actually at the client's computer say there's a row of desks all with PCS

78
00:05:23,520 --> 00:05:30,000
plugged into the internet you take your net tool you go I want all these

79
00:05:28,020 --> 00:05:35,400
computers to be on this VLAN you plug into all the ports it records the port

80
00:05:32,400 --> 00:05:37,680
on here you make your configuration and

81
00:05:35,400 --> 00:05:41,340
you click it bam it applies the configuration to all of those ports that

82
00:05:39,840 --> 00:05:45,900
you plugged into otherwise you would have to have a perfect map of what

83
00:05:43,860 --> 00:05:49,259
individual switch each client is plugged into and in a perfect world you should

84
00:05:47,520 --> 00:05:53,400
but having to reference that especially if you're talking in an environment with

85
00:05:50,880 --> 00:05:57,419
hundreds or thousands of clients that can get pretty tricky especially if you

86
00:05:55,919 --> 00:06:01,380
only want to change one or two you just walk in you go plug plug you set up your

87
00:05:59,340 --> 00:06:05,759
if then if you just want to apply a VLAN I guess you can probably just do that in

88
00:06:02,880 --> 00:06:11,340
here so you configure with untag VLAN say our untag VLAN is 100 and

89
00:06:08,400 --> 00:06:15,479
automatically Port VLAN things I think if we plug it in here

90
00:06:13,199 --> 00:06:19,259
in theory it should add it to the queue hey you did look at that switch

91
00:06:16,560 --> 00:06:23,460
configuration queue sick again this is really not meant for like a UniFi switch

92
00:06:21,419 --> 00:06:28,020
like this but you can see it did grab the port which I guess reports as the

93
00:06:25,380 --> 00:06:32,639
Mac Address it said we want two flag it as Port 100 and then you would just go

94
00:06:30,120 --> 00:06:36,360
and hit run assuming you set up the SSH credentials for the switch and whatnot

95
00:06:34,080 --> 00:06:41,280
bam it would apply it we configured the switch exactly how you want and then

96
00:06:38,280 --> 00:06:43,560
once that's done you can go well did it

97
00:06:41,280 --> 00:06:46,860
work I can scan it again and see if it applied the VLAN I'm getting the right

98
00:06:45,180 --> 00:06:51,419
IP let's see if it picks up the tagged vlans hey look at that what else can I

99
00:06:49,440 --> 00:06:57,419
do can I blink the port Flash the Lan Port that's very helpful tag history oh

100
00:06:54,300 --> 00:06:59,639
let's add a tag Jake computer you tag

101
00:06:57,419 --> 00:07:02,460
this discovery J computer ah sick it literally saved every single thing it

102
00:07:01,319 --> 00:07:06,780
read from it into like a little log file this thing

103
00:07:05,100 --> 00:07:09,240
has so many features to think that it's like a very small team that works on

104
00:07:08,400 --> 00:07:16,380
this thing for instance right now I can go in here and say I want to connect to let's say

105
00:07:13,979 --> 00:07:21,180
VLAN in theory rather than connecting to the native Network it would connect to

106
00:07:19,440 --> 00:07:26,280
that tagged VLAN that I provided which is great if you need to troubleshoot if a VLAN is working sometimes it seems to

107
00:07:24,419 --> 00:07:30,360
get stuck you can end up at the loading page pretty much infinitely and you kind

108
00:07:28,620 --> 00:07:35,819
of have to go back and reconnect maybe I didn't hit apply no it did hit apply

109
00:07:32,759 --> 00:07:37,919
because it restarted right yeah

110
00:07:35,819 --> 00:07:42,000
it occurs to me that we didn't check if there was a firmware update when he sent

111
00:07:39,900 --> 00:07:46,800
me the first one he was like make sure you update the firmware oh there's no

112
00:07:44,759 --> 00:07:52,319
updates available never mind to be entirely clear I have not tried the

113
00:07:49,680 --> 00:07:57,180
tagged VLAN mode I also don't know if this port is working properly because I

114
00:07:55,139 --> 00:08:02,639
tried to plug this one in and it wasn't working so

115
00:07:59,220 --> 00:08:05,039
I turned that off for now I'm sure it

116
00:08:02,639 --> 00:08:10,319
probably works but it didn't for me so your mileage may vary

117
00:08:07,080 --> 00:08:11,819
LMG 27 underscore two what the is

118
00:08:10,319 --> 00:08:15,180
that wait it showed up a couple weeks ago you didn't tell anyone

119
00:08:13,680 --> 00:08:19,319
do I have internet I'm pretty sure I do

120
00:08:17,160 --> 00:08:24,300
it's pretty cool that's so cool

121
00:08:22,259 --> 00:08:27,780
it's not very fast it's really really not fast

122
00:08:25,520 --> 00:08:31,560
I don't think it's made for speed test it checks for a lot of things it pings

123
00:08:30,060 --> 00:08:37,800
the Gateway which would be your router to see if that's working which is great it pings the internet in this instance

124
00:08:35,219 --> 00:08:43,200
google.com to check if your actual network has internet connection and then

125
00:08:39,479 --> 00:08:44,459
it also did an HTTP https request to

126
00:08:43,200 --> 00:08:49,680
make sure that it could load a website which to be working what else can we do

127
00:08:47,160 --> 00:08:54,000
Discovery timers there's so many Tools in this tool

128
00:08:51,600 --> 00:08:59,040
well I'm connected over Bluetooth still connect over Wi-Fi wow that's way faster

129
00:08:56,160 --> 00:09:02,279
over Wi-Fi what have I been doing you can configure timeouts for each of the

130
00:09:00,600 --> 00:09:05,820
different tests if you think that your lacp should only take 10 seconds and if

131
00:09:04,800 --> 00:09:10,440
it doesn't get it by then then something's wrong then you can set it to do that which is really nice Network

132
00:09:08,459 --> 00:09:15,420
time protocol yeah okay I guess it just syncs the device with ntp which is cool

133
00:09:12,300 --> 00:09:17,459
devices that's the current devices I

134
00:09:15,420 --> 00:09:20,940
noticed in the toggles that the STP option was disabled that might be why

135
00:09:19,440 --> 00:09:25,920
that page doesn't work let's see grabbing toggle switch settings

136
00:09:23,220 --> 00:09:29,040
STP Discovery let's try that I think because we just have a router we're

137
00:09:27,480 --> 00:09:33,959
plugged into a ubiquity dream machine there is no switches to spanning tree

138
00:09:32,580 --> 00:09:39,120
two um so it's not outputting any information

139
00:09:36,779 --> 00:09:42,540
what about Discovery packet yeah okay that gives us all the info there

140
00:09:40,800 --> 00:09:44,940
interesting you can set it to automatically save all of the

141
00:09:43,800 --> 00:09:49,440
discoveries so if you're running around trying to catalog a bunch of switches you can turn that on to auto save and by

142
00:09:48,360 --> 00:09:55,320
default you actually have to go in and click tag but let's try turning the ARP thing on let's say you want to find the

143
00:09:52,740 --> 00:09:59,640
IP of a razzpi you just set up or the ipmi IP address of a new server you

144
00:09:58,140 --> 00:10:03,420
would just plug into the same switch and in theory with the ARP table you should

145
00:10:01,320 --> 00:10:07,019
be able to find that device I think there's only a couple on here this is

146
00:10:05,160 --> 00:10:10,320
the router itself some computer that's plugged into this for testing and then

147
00:10:08,459 --> 00:10:13,500
this is the net tool itself and it also does a port scan of each of these

148
00:10:11,640 --> 00:10:16,320
devices especially for that ipmi one it should be able to find the web port for

149
00:10:15,000 --> 00:10:21,360
instance to be able to connect to that and it'll give you that information to know that that probably is the one

150
00:10:19,440 --> 00:10:25,740
you're looking for if it's running a web server versus a different device

151
00:10:23,399 --> 00:10:29,580
none of these ones have a web server right I don't think so

152
00:10:27,300 --> 00:10:32,459
these have a web server this one I think the router should have a web server

153
00:10:30,959 --> 00:10:36,600
right did I not turn that on properly maybe now I get to show you the coolest

154
00:10:34,500 --> 00:10:40,620
part net toolcloud some of you have probably already thought that wow this

155
00:10:38,580 --> 00:10:44,519
is a really cool tool I should buy one for all my level one techs shout out

156
00:10:42,839 --> 00:10:47,940
Wendell but you kind of need remote access a lot of the time the people that

157
00:10:46,440 --> 00:10:52,380
are going to be using a tool like this say like a level one technician that's

158
00:10:50,339 --> 00:10:55,620
trying to diagnose problems they're not going to have the kind of access needed

159
00:10:53,760 --> 00:10:58,800
to make changes and make fixes and whatnot something like this would be

160
00:10:57,000 --> 00:11:03,720
really powerful if it had that remote access well it does through net tool

161
00:11:01,500 --> 00:11:07,019
Cloud you can automatically sync any readings off of this device so you're

162
00:11:05,339 --> 00:11:10,200
trying to diagnose an issue with one of your lower level techs and trying to

163
00:11:08,519 --> 00:11:13,980
figure out what's going on they can hook it up scan the port get all the

164
00:11:11,940 --> 00:11:16,980
information and it'll automatically sync to the cloud and you can have a bunch of

165
00:11:15,540 --> 00:11:21,300
these connected to the same account so you have 10 technicians they've all got

166
00:11:19,079 --> 00:11:25,440
one of these you say let me just label it Jake's tester on well Jake's tester

167
00:11:24,240 --> 00:11:30,120
is getting this information was updated three minutes ago I can look at the

168
00:11:27,300 --> 00:11:35,519
historical tag discoveries I can look at the cloud specific history and add notes

169
00:11:33,060 --> 00:11:41,160
directly to it what is emulator does that let me oh no way oh my God okay so

170
00:11:39,240 --> 00:11:45,540
what happens if I unplug it oh it doesn't have internet anymore that makes

171
00:11:42,240 --> 00:11:46,980
sense okay well yeah okay I could have

172
00:11:45,540 --> 00:11:54,680
uh could have figured that one out myself we'll make a new network we'll call it

173
00:11:50,880 --> 00:11:54,680
test let's make it

174
00:11:55,279 --> 00:12:03,720
192.168.69.1 that one exists now and if we go to our port number two configure

175
00:12:00,420 --> 00:12:05,959
protocol test save hey look at that

176
00:12:03,720 --> 00:12:10,440
beautiful 192.168.69.120. it hasn't updated on

177
00:12:07,920 --> 00:12:15,240
here though the cloud feature is in beta so it probably still has some some Kinks

178
00:12:13,440 --> 00:12:19,760
to be worked out wait did it just update I don't know oh okay it updated

179
00:12:16,920 --> 00:12:25,260
beautiful there we go 192.168.69.120. again this part of it is

180
00:12:22,200 --> 00:12:28,440
very very beta I would not be surprised

181
00:12:25,260 --> 00:12:31,079
if it is just this finicky that's okay

182
00:12:28,440 --> 00:12:34,079
once it's working though this is really sick to be able to get all this

183
00:12:32,399 --> 00:12:37,980
information I can imagine they're probably working on ways to get all of

184
00:12:35,880 --> 00:12:41,940
these configurations and settings and everything able to be directly

185
00:12:39,779 --> 00:12:45,000
interfaced through the cloud so you would just have your remote hands and

186
00:12:43,320 --> 00:12:49,200
say hey idiot plug this thing in and I'll do all the work for you that would

187
00:12:46,680 --> 00:12:52,680
be freaking sweet right right now it's pretty read only

188
00:12:50,839 --> 00:12:56,160
but at least you can get that information and and yell at the person

189
00:12:54,480 --> 00:12:59,579
to fix it or maybe you can just get that information from the client side and

190
00:12:58,019 --> 00:13:03,180
you're fixing it on the server side bada bing bada boom now it's fixed other than

191
00:13:01,920 --> 00:13:07,920
that I mean I guess I didn't talk about what the differences are between the

192
00:13:04,980 --> 00:13:11,279
light and the main one it looks like if you're all you're trying to do is kind

193
00:13:09,120 --> 00:13:15,660
of troubleshooting and testing sort of stuff the light will fulfill most of

194
00:13:13,440 --> 00:13:19,200
those purposes the pro does add pcap capture which can be very helpful it

195
00:13:17,339 --> 00:13:24,899
also adds all of the port configuration and switch configuration stuff and ARP

196
00:13:21,600 --> 00:13:27,420
scanning but everything else DHCP

197
00:13:24,899 --> 00:13:31,980
detection IP detection Network detection flashing ports mapping the ports all

198
00:13:30,180 --> 00:13:36,720
this sort of stuff is on the light what's the pricing right now looks like

199
00:13:33,839 --> 00:13:40,860
199 for the light version and the pro is 299 decent price difference overall

200
00:13:39,300 --> 00:13:45,959
having the tool like this that can do this many Network related things for 200

201
00:13:43,740 --> 00:13:50,160
or 300 bucks I asked them to send another one this like I said I've been

202
00:13:47,639 --> 00:13:55,800
using into one wherever it is on the floor for like a couple weeks now and on

203
00:13:53,519 --> 00:14:00,420
the first day I was like yo can you send us more of these I I kind of want to

204
00:13:58,680 --> 00:14:03,839
have one for my house even it's just very flexible and it gives you so much

205
00:14:02,100 --> 00:14:08,339
information for not a lot of money and not a lot of time I would uh highly

206
00:14:06,060 --> 00:14:11,100
recommend checking this thing out and I can imagine how far they've already come

207
00:14:09,779 --> 00:14:14,399
in such a short amount of time with these devices I can't wait to see what

208
00:14:13,139 --> 00:14:18,899
they're going to be capable of in a couple years or like version three I

209
00:14:16,980 --> 00:14:23,459
mean if this thing also had like cable testing stuff obviously that's way more

210
00:14:22,260 --> 00:14:27,300
expensive kind of completely different device but

211
00:14:25,560 --> 00:14:33,600
if that was all integrated into one like a net tool Elite that would be freaking

212
00:14:30,420 --> 00:14:36,000
sick but for now

213
00:14:33,600 --> 00:14:40,860
I like this thing a lot if you like this video get subscribed to ShortCircuit

214
00:14:37,860 --> 00:14:42,600
and if you if you want to see more short

215
00:14:40,860 --> 00:14:47,480
circuit videos then go see more ShortCircuit videos I

216
00:14:44,820 --> 00:14:47,480
can't think of one
