 Hello and welcome today. We're gonna be looking at our Linux shell on the last video We looked how to check out your internet speeds from the shell Running a simple command speed test, but how do you test and that just grabs a server nearby for me? It was either Miami or Tampa or Tampa or Bonita, you know some town here in Florida Where there's a server that it can do speed tests on let's say you want to test the speeds on your local network from one Machine to another well That's what we're going to look at today and we're going to use this program IP erf So if you're on a debian-based system, you should be able to sudo apt or apt-getter or aptitude install IP erf. I don't know if you're supposed to pronounce it IPerf or IP Whatever that's the name of the command now you see I have two panes open here The top one here that I'm in right here is actually my server in the other room my Pogo plug server now the Bottom one is the machine that I'm currently on so I'm just SSH in there so you can see both so on one machine You're gonna want to log in and start a server So once you have IP erf installed just run the command IP erf space dash s and hit enter And it will be listening as a server now in the other window you can type in IP erf dash C to connect or client. I'm not sure Which one it stands for you are the client and you're connecting to and then you give it the IP address So the server in the other room that's currently is the the setup as a server for this is 192.168.1.2 But obviously you type in the IP address Whatever your machine is and when you hit enter you'll see on both of them They are now connected and they're doing a transfer speed test It's gonna go for about 10 seconds and that's gonna give you you know the speed of that It was able to transfer at so you see right here. It transferred just over 100 megabytes It took just over 10 seconds or just 10 seconds and you got your bandwidth speeds going and coming from the machines here Which is pretty good. You know, I don't know I have very cheap routers I would assume that if you had better routers, you probably would get better But I usually just buy the $20 deals online But now you can see your megabit rate and you can see what your router is supposed to get and are you really getting that now There's a lot of factors the speed of your machine like this machine up here that I'm running as the server as a Pogo plug Which is I don't know seven eight years old now and you can buy them online for seven dollars So it may not be the fastest machine I'm not sure what its Ethernet speeds are supposed to be so if I actually connected to my laptop Or something like that. That's a better machine. I might get better results than this but you know 94 megabits per second is is fine with me for I mean I'm just backing up file so sometimes it's large But just let it run. But anyway, if you wanted to test out your machines That's how you would do it test out the speeds on your local network So you just need to install this program on both machines again IP erf and then set up one as a server Just by doing IP erf dash s get that going and then on your other machine IP erf dash C and the IP address of the server you just set up I guess theoretically you could run this across, you know the internet as well if you had a server Remotely you could I guess do this as long as you know, you ended up you did port forwarding on your router or Have the militarized zone or something like that Obviously and if you have no clue I'm talking about well Then you need to learn a little bit more about networking before you start doing things remotely like that, but at least on my local network I can check the speeds, you know, again, it runs for about 10 seconds and it'll give me my Megabits per second transfer speed and it's that simple.
