1 00:00:06,750 --> 00:00:09,000 - All right, let's have a look at commands 2 00:00:09,000 --> 00:00:10,590 that we've seen in this lesson. 3 00:00:10,590 --> 00:00:12,240 It started with ip a, 4 00:00:12,240 --> 00:00:15,300 which is printing current IP address information. 5 00:00:15,300 --> 00:00:17,280 Next there was ip route show, 6 00:00:17,280 --> 00:00:19,170 which will show you your routing table, 7 00:00:19,170 --> 00:00:22,770 including the default route, which is important to verify. 8 00:00:22,770 --> 00:00:23,910 Then we have used ping, 9 00:00:23,910 --> 00:00:26,640 which is useful to verify connectivity. 10 00:00:26,640 --> 00:00:28,590 And ss for socket statistics. 11 00:00:28,590 --> 00:00:30,270 You can use it to verify ports 12 00:00:30,270 --> 00:00:32,250 that are listening on your system. 13 00:00:32,250 --> 00:00:36,183 And dig allows you to figure out your DNS configuration. 14 00:00:37,579 --> 00:00:39,300 We have had a look at nmap, 15 00:00:39,300 --> 00:00:41,880 an advanced security analysis utility 16 00:00:41,880 --> 00:00:44,250 that you can use to figure out information 17 00:00:44,250 --> 00:00:46,170 about your network config. 18 00:00:46,170 --> 00:00:50,340 Hostname and hostnamectl were the last utilities. 19 00:00:50,340 --> 00:00:53,010 They're all about host name management. 20 00:00:53,010 --> 00:00:53,880 And that's all. 21 00:00:53,880 --> 00:00:55,053 Let's check out a lab.
