1 00:00:06,150 --> 00:00:10,380 - Challenge: Configuring IP with PowerShell. 2 00:00:10,380 --> 00:00:13,020 Are you tired of clicking around the GUI? 3 00:00:13,020 --> 00:00:17,070 Use PowerShell, use the command line. 4 00:00:17,070 --> 00:00:20,910 In this lab, we'll configure a static IP 5 00:00:20,910 --> 00:00:23,913 version 4 address within PowerShell. 6 00:00:24,960 --> 00:00:27,910 To do this, we'll use the following format 7 00:00:28,920 --> 00:00:32,520 and we're gonna use the netsh command. 8 00:00:32,520 --> 00:00:36,210 This command could do all kinds of things in Windows, 9 00:00:36,210 --> 00:00:40,410 we're just gonna use it here to configure TCP/IP. 10 00:00:40,410 --> 00:00:43,320 And for this command we're gonna use netsh 11 00:00:43,320 --> 00:00:45,813 and a lot of options and parameters. 12 00:00:46,710 --> 00:00:51,710 It's going to be netsh interface, IP set address 13 00:00:52,440 --> 00:00:54,480 and then your connection name. 14 00:00:54,480 --> 00:00:58,050 By default in Windows, if you have a wired connection 15 00:00:58,050 --> 00:01:01,890 that connection's name will be called ethernet 16 00:01:01,890 --> 00:01:04,620 and that's what I'll be using in the demonstration 17 00:01:04,620 --> 00:01:06,480 in just a minute. 18 00:01:06,480 --> 00:01:08,820 Then we'll say static because we're going 19 00:01:08,820 --> 00:01:12,120 to manually configure the IP address 20 00:01:12,120 --> 00:01:14,820 and then we'll enter the actual IP version 21 00:01:14,820 --> 00:01:17,760 4 address that we want to use, 22 00:01:17,760 --> 00:01:21,300 as well as the IP version 4 subnet mask 23 00:01:21,300 --> 00:01:23,223 and the gateway address. 24 00:01:25,500 --> 00:01:28,770 Afterward, we'll add a DNS server 25 00:01:28,770 --> 00:01:33,770 so that we can do our name to IP resolution. 26 00:01:33,960 --> 00:01:38,280 And once again, we'll use the netsh interface IP command, 27 00:01:38,280 --> 00:01:42,120 but this time we'll type add DNS, 28 00:01:42,120 --> 00:01:43,980 once again our connection name 29 00:01:43,980 --> 00:01:47,820 and then the IP address of our DNS server. 30 00:01:47,820 --> 00:01:49,920 After we do that, we'll test it 31 00:01:49,920 --> 00:01:52,050 and make sure that it can function 32 00:01:52,050 --> 00:01:54,780 and that we can connect to the internet. 33 00:01:54,780 --> 00:01:58,180 When we're done, we'll set it back to DHCP 34 00:01:59,100 --> 00:02:04,100 and the command for that netsh interface IP set address, 35 00:02:04,380 --> 00:02:07,113 the connection name and just DHCP. 36 00:02:08,700 --> 00:02:10,953 So let's get into the demonstration now. 37 00:02:11,820 --> 00:02:16,820 I'm going to be doing this on a Windows 11 virtual machine 38 00:02:17,190 --> 00:02:22,190 and we want to open up PowerShell as an administrator. 39 00:02:22,830 --> 00:02:25,380 Several ways to do this. 40 00:02:25,380 --> 00:02:28,080 In Windows 11 you could right click on start 41 00:02:28,080 --> 00:02:29,580 and open Windows Terminal, 42 00:02:29,580 --> 00:02:32,070 which will automatically open PowerShell. 43 00:02:32,070 --> 00:02:34,233 And you'd wanna do that as an admin, 44 00:02:35,160 --> 00:02:38,520 or we could press the Windows key 45 00:02:38,520 --> 00:02:41,280 and type in PowerShell 46 00:02:41,280 --> 00:02:42,810 and run it from there, 47 00:02:42,810 --> 00:02:46,380 or do it from the run prompt and type PowerShell. 48 00:02:46,380 --> 00:02:50,890 And to run it as an admin we'd press control shift enter 49 00:02:51,960 --> 00:02:53,700 but I like the search option. 50 00:02:53,700 --> 00:02:54,810 It's very easy. 51 00:02:54,810 --> 00:02:57,540 We can right click on Windows PowerShell 52 00:02:57,540 --> 00:02:59,733 and select run as administrator. 53 00:03:01,793 --> 00:03:02,770 And we'll say yes 54 00:03:04,020 --> 00:03:06,570 and that brings up the Windows PowerShell 55 00:03:06,570 --> 00:03:09,930 as an administrator, meaning in elevated mode. 56 00:03:09,930 --> 00:03:12,150 So now we can do these types of commands 57 00:03:12,150 --> 00:03:14,940 that we need to do as an admin. 58 00:03:14,940 --> 00:03:18,360 I'm going to change to the root directory 59 00:03:18,360 --> 00:03:20,490 and clear the screen with a control L 60 00:03:20,490 --> 00:03:23,370 so that we have a little bit more space here. 61 00:03:23,370 --> 00:03:24,630 And the first thing I wanna do 62 00:03:24,630 --> 00:03:28,053 is run an IP config slash all, 63 00:03:28,890 --> 00:03:32,103 to check out the current IP configuration. 64 00:03:33,270 --> 00:03:36,180 Now, as I mentioned, this is a virtual machine 65 00:03:36,180 --> 00:03:40,620 and it's on a virtualization platform 66 00:03:40,620 --> 00:03:45,090 that automatically hands out IP addresses. 67 00:03:45,090 --> 00:03:47,340 I know that this virtual machine 68 00:03:47,340 --> 00:03:50,790 is obtaining its IP address from a DHCP server. 69 00:03:50,790 --> 00:03:54,810 I know that because here it says DHCP enabled 70 00:03:54,810 --> 00:03:56,460 and yes. 71 00:03:56,460 --> 00:03:59,190 So we know we're getting our TCP/IP information 72 00:03:59,190 --> 00:04:00,930 from a DHCP server. 73 00:04:00,930 --> 00:04:03,840 And that's the DHCP server that's built into 74 00:04:03,840 --> 00:04:05,643 my virtualization platform. 75 00:04:07,410 --> 00:04:10,470 The IP version 4 address that we received 76 00:04:10,470 --> 00:04:15,470 is 192.168.122.63. 77 00:04:15,900 --> 00:04:19,440 So the IP network that my virtualization platform 78 00:04:19,440 --> 00:04:23,250 is using here is 192.168.122. 79 00:04:23,250 --> 00:04:26,940 I wanna stay on that particular network. 80 00:04:26,940 --> 00:04:30,510 What differentiates this system from other systems 81 00:04:30,510 --> 00:04:33,633 is the last octet, that dot 63. 82 00:04:34,590 --> 00:04:39,270 And I'll be changing that when we set a static IP address. 83 00:04:39,270 --> 00:04:41,790 We're also getting the subnet mask information 84 00:04:41,790 --> 00:04:46,443 from the DHCP server which is 255.255.255.0. 85 00:04:48,270 --> 00:04:50,460 We also see the default gateway 86 00:04:50,460 --> 00:04:55,020 which is 192.168.122.1, 87 00:04:55,020 --> 00:04:59,670 and the DNS server, which is the same host. 88 00:04:59,670 --> 00:05:03,900 Now you might do this on a network with the Soho router 89 00:05:03,900 --> 00:05:05,730 and it would work in the same manner. 90 00:05:05,730 --> 00:05:09,630 Your network might be 192.168.0, 91 00:05:09,630 --> 00:05:12,480 or 192.168.1. 92 00:05:12,480 --> 00:05:14,730 Or if you're on a different virtualization platform, 93 00:05:14,730 --> 00:05:17,070 it might be a different network as well. 94 00:05:17,070 --> 00:05:18,900 So whatever that network is, 95 00:05:18,900 --> 00:05:22,350 that's the network that you want to work within. 96 00:05:22,350 --> 00:05:23,640 So I'm gonna change this now, 97 00:05:23,640 --> 00:05:26,580 I don't want to have DHCP anymore. 98 00:05:26,580 --> 00:05:28,830 A lot of times I'll be working on a system 99 00:05:28,830 --> 00:05:32,790 and I want it to have a static IP address 100 00:05:32,790 --> 00:05:37,590 so that I know the IP address will not change 101 00:05:37,590 --> 00:05:39,360 and I can have permanent connections 102 00:05:39,360 --> 00:05:42,440 to that system via that static IP. 103 00:05:42,440 --> 00:05:45,300 So a lot of times I'll use a static IP address. 104 00:05:45,300 --> 00:05:47,640 So let's make the change now. 105 00:05:47,640 --> 00:05:50,070 We're gonna do that with the netsh command 106 00:05:50,070 --> 00:05:52,470 and that's gonna be interface 107 00:05:52,470 --> 00:05:56,880 and IP set address. 108 00:05:56,880 --> 00:05:58,350 And then we need the name 109 00:05:58,350 --> 00:06:02,970 of our wired network interface card. 110 00:06:02,970 --> 00:06:05,040 Now, again, this is a virtual machine 111 00:06:05,040 --> 00:06:07,680 so it uses virtualized hardware, 112 00:06:07,680 --> 00:06:10,470 but it works the same way as a physical system. 113 00:06:10,470 --> 00:06:13,170 And what we wanna look for is ethernet adapter 114 00:06:13,170 --> 00:06:15,480 and then the name that's after that. 115 00:06:15,480 --> 00:06:17,400 By default in Windows, 116 00:06:17,400 --> 00:06:21,660 the name of a wired connection is called ethernet. 117 00:06:21,660 --> 00:06:23,580 If you're working with a wireless connection, 118 00:06:23,580 --> 00:06:25,263 the default name is wifi. 119 00:06:26,130 --> 00:06:29,280 You could change this in the PowerShell if you wanted to, 120 00:06:29,280 --> 00:06:32,460 but we're gonna stick with the name ethernet. 121 00:06:32,460 --> 00:06:34,443 And we wanna put that in double quotes. 122 00:06:36,030 --> 00:06:37,170 So we'll add that in now, 123 00:06:37,170 --> 00:06:39,020 you can see the different color there 124 00:06:39,930 --> 00:06:42,270 and then we want to state 125 00:06:42,270 --> 00:06:45,210 that we are going to add a static IP address. 126 00:06:45,210 --> 00:06:46,860 So we put in the word static 127 00:06:46,860 --> 00:06:48,960 and then the IP address I want to use. 128 00:06:48,960 --> 00:06:51,840 Well, I'm gonna use the same network 129 00:06:51,840 --> 00:06:53,760 but I'm gonna change the last octet. 130 00:06:53,760 --> 00:06:58,760 And I'm just gonna change it to say, .150. 131 00:06:59,430 --> 00:07:00,900 It doesn't really matter, 132 00:07:00,900 --> 00:07:05,900 as long as the address that I select is not being used 133 00:07:06,030 --> 00:07:08,070 by any other systems. 134 00:07:08,070 --> 00:07:13,070 So I'm going to type 192.168.122.150. 135 00:07:14,580 --> 00:07:17,400 Next, we need the subnet mask 136 00:07:17,400 --> 00:07:19,350 and I'm gonna use the same subnet mask 137 00:07:19,350 --> 00:07:21,040 that I'm currently using, 138 00:07:21,040 --> 00:07:23,640 255.255.255.0. 139 00:07:23,640 --> 00:07:26,700 And that just wrapped around the screen there. 140 00:07:26,700 --> 00:07:30,120 Now you could also do something like this 141 00:07:30,120 --> 00:07:31,503 slash 24, 142 00:07:32,730 --> 00:07:34,470 which is cidr notation, 143 00:07:34,470 --> 00:07:36,300 it's the same thing. 144 00:07:36,300 --> 00:07:41,300 For now I'll just do 255.255.255.0, 145 00:07:42,030 --> 00:07:43,860 and then we need to know the gateway address. 146 00:07:43,860 --> 00:07:47,190 It's gonna be the same default gateway. 147 00:07:47,190 --> 00:07:49,290 So we'll type in this IP. 148 00:07:49,290 --> 00:07:52,200 For you, it may be different on your system. 149 00:07:52,200 --> 00:07:55,590 It probably will be, but that's the IP for me, 150 00:07:55,590 --> 00:07:58,770 192.168.122.1. 151 00:07:58,770 --> 00:08:00,663 And that's it, that's our command. 152 00:08:01,680 --> 00:08:02,763 So we'll press enter, 153 00:08:04,350 --> 00:08:07,350 that will apply the new information, 154 00:08:07,350 --> 00:08:11,580 deactivate and reactivate the network interface. 155 00:08:11,580 --> 00:08:14,943 And then we can check that with an IP config slash all. 156 00:08:16,980 --> 00:08:21,907 Okay. Now, when we look at DHCP enabled, it says, no. 157 00:08:23,310 --> 00:08:26,340 We're not using DHCP anymore, it's a static IP. 158 00:08:26,340 --> 00:08:28,980 When we look at the IP version 4 address, 159 00:08:28,980 --> 00:08:33,980 we see 192.168.122.150. 160 00:08:34,740 --> 00:08:36,990 And we have our default gateway. 161 00:08:36,990 --> 00:08:41,100 Now the DNS server is already there, 162 00:08:41,100 --> 00:08:44,160 but if you had a problem with that, 163 00:08:44,160 --> 00:08:46,260 if there was an issue with DNS, 164 00:08:46,260 --> 00:08:47,820 you could add that on 165 00:08:47,820 --> 00:08:52,780 and you would do that with the netsh interface IP, add DNS 166 00:08:55,140 --> 00:08:57,700 for our ethernet connection 167 00:08:58,860 --> 00:09:03,240 and then specify the IP address 192.168.122.1. 168 00:09:06,450 --> 00:09:08,700 And it says the object is already in the list, 169 00:09:08,700 --> 00:09:11,670 but just in the case that it wasn't there, 170 00:09:11,670 --> 00:09:14,160 if you lost it for some reason, 171 00:09:14,160 --> 00:09:17,490 or it didn't show up when you changed over to static, 172 00:09:17,490 --> 00:09:20,400 then you could add that with this command. 173 00:09:20,400 --> 00:09:24,180 Now we want to go ahead and test it and make sure it works. 174 00:09:24,180 --> 00:09:26,710 So I'm gonna ping a website 175 00:09:27,720 --> 00:09:28,553 on the internet 176 00:09:29,790 --> 00:09:31,710 and we get replies. 177 00:09:31,710 --> 00:09:35,040 We can ping Depro Computer so we know the test has passed 178 00:09:35,040 --> 00:09:37,440 and we should be able to do anything we need to do 179 00:09:37,440 --> 00:09:40,890 with our internet connection, inbound and outbound. 180 00:09:40,890 --> 00:09:41,723 That's it. 181 00:09:41,723 --> 00:09:44,253 That's how you change to a static IP. 182 00:09:45,240 --> 00:09:48,300 Now let's go ahead and change it back to DHCP. 183 00:09:48,300 --> 00:09:53,300 And we'll do that with the netsh interface IP set address 184 00:09:56,670 --> 00:10:01,293 and the name's ethernet, and just say DHCP. 185 00:10:02,280 --> 00:10:04,530 That's gonna make the change deactivate 186 00:10:04,530 --> 00:10:07,050 and reactivate the network interface. 187 00:10:07,050 --> 00:10:09,330 And then I'll just up arrow 188 00:10:09,330 --> 00:10:12,093 to IP config slash all to check it. 189 00:10:13,140 --> 00:10:16,593 Once again, DHCP enabled, yes. 190 00:10:19,230 --> 00:10:22,860 IP version 4 address dot 63. 191 00:10:22,860 --> 00:10:27,153 Well, Windows remembers the IP address that we were using. 192 00:10:28,320 --> 00:10:29,790 And it reapplies to that, 193 00:10:29,790 --> 00:10:32,343 as long as the DHCP server is okay with that. 194 00:10:33,390 --> 00:10:35,310 Our gateway address is there 195 00:10:35,310 --> 00:10:38,490 and our DNS server is there. 196 00:10:38,490 --> 00:10:40,563 We'll test once again with a ping, 197 00:10:41,580 --> 00:10:42,513 all as well. 198 00:10:43,890 --> 00:10:46,980 Okay? So the only things you might change with that 199 00:10:46,980 --> 00:10:48,330 are your network number. 200 00:10:48,330 --> 00:10:51,240 You want to put in whatever network number you're using. 201 00:10:51,240 --> 00:10:53,040 For example, if you're on VirtualBox 202 00:10:53,040 --> 00:10:55,443 you're probably on 10.0.2. 203 00:10:56,280 --> 00:10:58,440 If you're on VMware Workstation, 204 00:10:58,440 --> 00:11:01,650 you might be using another 192.168 network. 205 00:11:01,650 --> 00:11:03,450 If you're working on the local area network 206 00:11:03,450 --> 00:11:05,790 on a test computer, like a laptop 207 00:11:05,790 --> 00:11:07,230 and you have a Soho network 208 00:11:07,230 --> 00:11:12,060 it might be 192.168.0, or .1, or what have you. 209 00:11:12,060 --> 00:11:15,150 And the name of the adapter, if it's wired, 210 00:11:15,150 --> 00:11:17,130 by default will be ethernet. 211 00:11:17,130 --> 00:11:20,880 By default, if it's wireless, it'll be wifi. 212 00:11:20,880 --> 00:11:23,280 And make sure you put that in double quotes. 213 00:11:23,280 --> 00:11:26,700 Now you'll notice that we have the blue background here. 214 00:11:26,700 --> 00:11:30,933 If we were to run the command dollar sign PS version table, 215 00:11:32,580 --> 00:11:35,520 you'll see that the PowerShell version 216 00:11:35,520 --> 00:11:37,680 that I'm running is 5.1. 217 00:11:37,680 --> 00:11:39,300 This is an older version. 218 00:11:39,300 --> 00:11:42,720 We have much newer versions of PowerShell. 219 00:11:42,720 --> 00:11:45,150 And so in another challenge video 220 00:11:45,150 --> 00:11:49,350 we'll show how to update PowerShell to a newer version. 221 00:11:49,350 --> 00:11:51,270 Now, one other thing here, 222 00:11:51,270 --> 00:11:52,710 sometimes we'll be working on a system 223 00:11:52,710 --> 00:11:55,770 that has lots of network connections. 224 00:11:55,770 --> 00:11:58,080 For example, here's a Windows laptop. 225 00:11:58,080 --> 00:12:01,833 I'm gonna open up PowerShell on here as an administrator, 226 00:12:02,970 --> 00:12:06,360 say yes to that, bring that up. 227 00:12:06,360 --> 00:12:11,360 And if I run an IP config on here with a slash all, 228 00:12:11,820 --> 00:12:15,480 you're gonna see tons and tons and tons of information 229 00:12:15,480 --> 00:12:17,640 and the Bluetooth and the wireless 230 00:12:17,640 --> 00:12:19,140 aren't even connected right now. 231 00:12:19,140 --> 00:12:21,900 So it's limited, but there's still tons of information. 232 00:12:21,900 --> 00:12:23,490 There's all kinds of virtual networks 233 00:12:23,490 --> 00:12:26,220 and wired connection and blah, blah, blah. 234 00:12:26,220 --> 00:12:29,250 That's a lot of information to look at 235 00:12:29,250 --> 00:12:31,440 within IP config slash all. 236 00:12:31,440 --> 00:12:33,150 So if you're working on a server 237 00:12:33,150 --> 00:12:34,680 with lots of network connections, 238 00:12:34,680 --> 00:12:37,860 or if you're working on a power works station 239 00:12:37,860 --> 00:12:40,800 with lots of connections or maybe a developer laptop 240 00:12:40,800 --> 00:12:43,140 with lots of virtual connections, 241 00:12:43,140 --> 00:12:46,200 sometimes you may wanna filter this information. 242 00:12:46,200 --> 00:12:49,170 So you might do an IP config slash all 243 00:12:49,170 --> 00:12:51,060 with the pipe sign 244 00:12:51,060 --> 00:12:56,060 and do select string, run the SLS parameter here 245 00:12:56,280 --> 00:12:59,910 and then filter for what you want. 246 00:12:59,910 --> 00:13:03,930 So for example, I might filter for description 247 00:13:03,930 --> 00:13:07,770 and also IP version 4. 248 00:13:07,770 --> 00:13:09,090 When I do that, 249 00:13:09,090 --> 00:13:12,870 I get a lot less information and just what I want. 250 00:13:12,870 --> 00:13:15,690 So for example, description, 251 00:13:15,690 --> 00:13:18,600 real tech PCI express controller. 252 00:13:18,600 --> 00:13:20,940 That's the wired connection 253 00:13:20,940 --> 00:13:25,940 and its IP version 4 address is 10.42.0.250. 254 00:13:27,300 --> 00:13:29,520 And you can do that for each of these here, 255 00:13:29,520 --> 00:13:30,990 all of the connections. 256 00:13:30,990 --> 00:13:35,130 So just a quick little trick there, use SLS 257 00:13:35,130 --> 00:13:38,130 to filter out results of commands 258 00:13:38,130 --> 00:13:39,930 that give you tons of information, 259 00:13:39,930 --> 00:13:41,343 just a little bonus there. 260 00:13:42,180 --> 00:13:43,013 All right. 261 00:13:43,013 --> 00:13:45,660 And like I said, in a future video we'll show how to upgrade 262 00:13:45,660 --> 00:13:48,960 to the latest stable version of PowerShell. 263 00:13:48,960 --> 00:13:52,500 And in closing, go ahead now, 264 00:13:52,500 --> 00:13:57,120 I challenge you to try configuring a new IP address 265 00:13:57,120 --> 00:14:02,070 on a test Windows system, now I recommend a virtual machine 266 00:14:02,070 --> 00:14:04,950 but some test system always do all this stuff 267 00:14:04,950 --> 00:14:09,300 on testing systems, not your main system. 268 00:14:09,300 --> 00:14:12,960 And remember to run PowerShell as an admin, 269 00:14:12,960 --> 00:14:17,190 chances are you will need PowerShell in the field. 270 00:14:17,190 --> 00:14:18,393 Use it.
