when it comes to diagnosing networking problems say you're an I.T person you're
just at your house whatever there are lots of tools on the market except so
many of them cost a thousand dollars or five thousand dollars or ten thousand
dollars this one isn't specifically designed to help with Hardware problems
but rather I guess you call it software problems configuration problems and also
to make configuring your network faster these are the net tool i o Pro 2 and I
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
since we get in here let's open this one ah
what is this oh this is the actual thing beautiful
there's one that's the light oh the
green is nice look at that
we've got a little quick start guide charger patch cable stickers I'll be
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
is the light I like the green though I have the pro one here I've been using it
for a few days this looks way cooler color wise why is it the cheaper
crappier one that looks cooler
color matched cables that's cute wow
we got matched stickers oh that makes
sense wonderful noise
it's gonna be a type c to a cable plugs in on the bottom there
just like that to charge these things do have a battery in it which is very
helpful you don't have to carry this thing around and ah is there a plug
there that would make this a very stupid tool 2500 milliamp hour battery in each
of them I played around with it for about a day the pro version and I maybe
went down like 30 battery life so on the bottom of each of them you have a port
for charging and then a port for USB connectivity I'm not sure what other
stuff you can do but you can at the very least do pcap capture to a USB stick
which is pretty helpful on the top is the Ethernet Jack that's going to plug
into a network switch or I guess a wall jack whatever you're trying to diagnose
or get information from yeah aside from that it's just the little LEDs on the
front and power buttons the top is a port activity indicator the second one
probably status of some point it's got a little like heartbeat sign which makes
me think it tells you what's going on currently and then battery indicator I
never used the first generation of these tools I know that this these are the
second generation ones I don't know what the main differences are but I do know
that these ones have both Wi-Fi and Bluetooth which is super cool when I
plug this thing in and turn the Wi-Fi hotspot on and connected my phone it
actually acted as an access point to give my phone internet through the cable
that it was plugged into which is super cool what app do we got here net tool I
think I have the pro one already yeah oh wait what
oh Pro 2. ah so the original one must have been
called the nettool.io and then the pro version was the net tool i o Pro and
then there's the Pro 2 and the light which is the two ones we have today kind
of seems like it could be one app I'm not gonna lie but I know that they're a
relatively small company so if this makes it a lot easier then cool
you look at that it's detected over Bluetooth and we'll check it out as soon as I tell
you about our sponsor secret lab chairs are engineered to keep you incredibly
comfortable for long hours at work and play their Titan Evo 2022 chair keeps
you feeling comfortable for longer with four-way lumbar support and Ultra
comfortable line of different seat materials and more not to mention all chairs come with a five-year extended
warranty and a 49 day return policy so head to the link down below and check
out secret lab today whoa so immediately it's got Lan ipv4
IPv6 it shows us The Gateway the configured DNS servers the subnet the
DHCP server IP shows you the domain shows you the public IP address the port
Mac Address the host name of the switch the type of switch oh my God to be clear
I've been using this for a few weeks just to try it out and one of the the
most useful things is being able to just go hey someone's having weird issues
with this port they're not getting an IP address well let's see if it maybe it's
their device I can just walk over there plug into the port let's see if it gets
an IP address boom it gets an IP address clearly there's something wrong with the
device not the switch or the port it's so nice to be able to to carry this
thing around and just plug into things let's see what else we could do of
course the most important setting at the top dark mode oh God this is supposed to
be one of the big selling features of the pro is the switch configurator I
don't think it would work with this little UniFi switch because it's managed
through ubiquity Zone interface but if you have like a Dell switch or Cisco
switch you can go in here and configure a lot of different things the if is
going to be whatever the command line is currently outputting as kind of your
start so let's say that's the start you go switch underscore Port this is a
placeholder as you can see up here is a key to import the current switchboard
that you're plugged into now that we have a template filled that we we can go into the configuration queue oh it shows
you what the configuration capabilities are that's really cool I really wish I
had something to try this part with man I was trying to wrap my head around what
this would be useful for in terms of configuring unless you just had to write
out like a whole script even if you're using like a touch interface it's still
kind of annoying but it all makes sense now say you're in an office building and
you're actually at the client's computer say there's a row of desks all with PCS
plugged into the internet you take your net tool you go I want all these
computers to be on this VLAN you plug into all the ports it records the port
on here you make your configuration and
you click it bam it applies the configuration to all of those ports that
you plugged into otherwise you would have to have a perfect map of what
individual switch each client is plugged into and in a perfect world you should
but having to reference that especially if you're talking in an environment with
hundreds or thousands of clients that can get pretty tricky especially if you
only want to change one or two you just walk in you go plug plug you set up your
if then if you just want to apply a VLAN I guess you can probably just do that in
here so you configure with untag VLAN say our untag VLAN is 100 and
automatically Port VLAN things I think if we plug it in here
in theory it should add it to the queue hey you did look at that switch
configuration queue sick again this is really not meant for like a UniFi switch
like this but you can see it did grab the port which I guess reports as the
Mac Address it said we want two flag it as Port 100 and then you would just go
and hit run assuming you set up the SSH credentials for the switch and whatnot
bam it would apply it we configured the switch exactly how you want and then
once that's done you can go well did it
work I can scan it again and see if it applied the VLAN I'm getting the right
IP let's see if it picks up the tagged vlans hey look at that what else can I
do can I blink the port Flash the Lan Port that's very helpful tag history oh
let's add a tag Jake computer you tag
this discovery J computer ah sick it literally saved every single thing it
read from it into like a little log file this thing
has so many features to think that it's like a very small team that works on
this thing for instance right now I can go in here and say I want to connect to let's say
VLAN in theory rather than connecting to the native Network it would connect to
that tagged VLAN that I provided which is great if you need to troubleshoot if a VLAN is working sometimes it seems to
get stuck you can end up at the loading page pretty much infinitely and you kind
of have to go back and reconnect maybe I didn't hit apply no it did hit apply
because it restarted right yeah
it occurs to me that we didn't check if there was a firmware update when he sent
me the first one he was like make sure you update the firmware oh there's no
updates available never mind to be entirely clear I have not tried the
tagged VLAN mode I also don't know if this port is working properly because I
tried to plug this one in and it wasn't working so
I turned that off for now I'm sure it
probably works but it didn't for me so your mileage may vary
LMG 27 underscore two what the is
that wait it showed up a couple weeks ago you didn't tell anyone
do I have internet I'm pretty sure I do
it's pretty cool that's so cool
it's not very fast it's really really not fast
I don't think it's made for speed test it checks for a lot of things it pings
the Gateway which would be your router to see if that's working which is great it pings the internet in this instance
google.com to check if your actual network has internet connection and then
it also did an HTTP https request to
make sure that it could load a website which to be working what else can we do
Discovery timers there's so many Tools in this tool
well I'm connected over Bluetooth still connect over Wi-Fi wow that's way faster
over Wi-Fi what have I been doing you can configure timeouts for each of the
different tests if you think that your lacp should only take 10 seconds and if
it doesn't get it by then then something's wrong then you can set it to do that which is really nice Network
time protocol yeah okay I guess it just syncs the device with ntp which is cool
devices that's the current devices I
noticed in the toggles that the STP option was disabled that might be why
that page doesn't work let's see grabbing toggle switch settings
STP Discovery let's try that I think because we just have a router we're
plugged into a ubiquity dream machine there is no switches to spanning tree
two um so it's not outputting any information
what about Discovery packet yeah okay that gives us all the info there
interesting you can set it to automatically save all of the
discoveries so if you're running around trying to catalog a bunch of switches you can turn that on to auto save and by
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
IP of a razzpi you just set up or the ipmi IP address of a new server you
would just plug into the same switch and in theory with the ARP table you should
be able to find that device I think there's only a couple on here this is
the router itself some computer that's plugged into this for testing and then
this is the net tool itself and it also does a port scan of each of these
devices especially for that ipmi one it should be able to find the web port for
instance to be able to connect to that and it'll give you that information to know that that probably is the one
you're looking for if it's running a web server versus a different device
none of these ones have a web server right I don't think so
these have a web server this one I think the router should have a web server
right did I not turn that on properly maybe now I get to show you the coolest
part net toolcloud some of you have probably already thought that wow this
is a really cool tool I should buy one for all my level one techs shout out
Wendell but you kind of need remote access a lot of the time the people that
are going to be using a tool like this say like a level one technician that's
trying to diagnose problems they're not going to have the kind of access needed
to make changes and make fixes and whatnot something like this would be
really powerful if it had that remote access well it does through net tool
Cloud you can automatically sync any readings off of this device so you're
trying to diagnose an issue with one of your lower level techs and trying to
figure out what's going on they can hook it up scan the port get all the
information and it'll automatically sync to the cloud and you can have a bunch of
these connected to the same account so you have 10 technicians they've all got
one of these you say let me just label it Jake's tester on well Jake's tester
is getting this information was updated three minutes ago I can look at the
historical tag discoveries I can look at the cloud specific history and add notes
directly to it what is emulator does that let me oh no way oh my God okay so
what happens if I unplug it oh it doesn't have internet anymore that makes
sense okay well yeah okay I could have
uh could have figured that one out myself we'll make a new network we'll call it
test let's make it
192.168.69.1 that one exists now and if we go to our port number two configure
protocol test save hey look at that
beautiful 192.168.69.120. it hasn't updated on
here though the cloud feature is in beta so it probably still has some some Kinks
to be worked out wait did it just update I don't know oh okay it updated
beautiful there we go 192.168.69.120. again this part of it is
very very beta I would not be surprised
if it is just this finicky that's okay
once it's working though this is really sick to be able to get all this
information I can imagine they're probably working on ways to get all of
these configurations and settings and everything able to be directly
interfaced through the cloud so you would just have your remote hands and
say hey idiot plug this thing in and I'll do all the work for you that would
be freaking sweet right right now it's pretty read only
but at least you can get that information and and yell at the person
to fix it or maybe you can just get that information from the client side and
you're fixing it on the server side bada bing bada boom now it's fixed other than
that I mean I guess I didn't talk about what the differences are between the
light and the main one it looks like if you're all you're trying to do is kind
of troubleshooting and testing sort of stuff the light will fulfill most of
those purposes the pro does add pcap capture which can be very helpful it
also adds all of the port configuration and switch configuration stuff and ARP
scanning but everything else DHCP
detection IP detection Network detection flashing ports mapping the ports all
this sort of stuff is on the light what's the pricing right now looks like
199 for the light version and the pro is 299 decent price difference overall
having the tool like this that can do this many Network related things for 200
or 300 bucks I asked them to send another one this like I said I've been
using into one wherever it is on the floor for like a couple weeks now and on
the first day I was like yo can you send us more of these I I kind of want to
have one for my house even it's just very flexible and it gives you so much
information for not a lot of money and not a lot of time I would uh highly
recommend checking this thing out and I can imagine how far they've already come
in such a short amount of time with these devices I can't wait to see what
they're going to be capable of in a couple years or like version three I
mean if this thing also had like cable testing stuff obviously that's way more
expensive kind of completely different device but
if that was all integrated into one like a net tool Elite that would be freaking
sick but for now
I like this thing a lot if you like this video get subscribed to ShortCircuit
and if you if you want to see more short
circuit videos then go see more ShortCircuit videos I
can't think of one
