1
00:00:01,350 --> 00:00:06,520
You can also view the connections to the Rotto switch by using the show uses command.

2
00:00:06,810 --> 00:00:15,810
So show uses shows us that we connected via cons. zero but we also connected via a telnet session from

3
00:00:16,020 --> 00:00:18,690
this IP address.

4
00:00:18,690 --> 00:00:28,930
So if I exit out of the telnet session show users now shows that we only connected via the console log

5
00:00:28,930 --> 00:00:32,630
in vide the telnet session again show uses.

6
00:00:32,700 --> 00:00:40,720
Shows us that the telnet session is now active I'll jump back to Route 1 using the keystrokes control

7
00:00:40,720 --> 00:00:46,800
shift 6 x and open up a nut the telnet session.

8
00:00:47,370 --> 00:00:57,130
Show users now shows us that David is connected to Viti y 0 as well as to why one control shift to 6

9
00:00:57,130 --> 00:01:07,020
x open up another session control shifts 6 x to another.

10
00:01:07,080 --> 00:01:21,000
So we now have four Etiwanda sessions open jumped back Mother told that session show uses we now connect

11
00:01:21,000 --> 00:01:21,730
to.

12
00:01:22,010 --> 00:01:24,760
And what's interesting is not just the username is not case sensitive.

13
00:01:24,770 --> 00:01:28,250
In this example but the past that is case sensitive.

14
00:01:28,250 --> 00:01:36,100
So we've got one two three four five evictee why sessions for jump back to the rot.

15
00:01:36,110 --> 00:01:39,640
Now Rodda one and try and telnet again.

16
00:01:39,930 --> 00:01:53,480
Notice the session is refused because we only enabled 5 V-twin y sessions from 0 to full at the moment.

17
00:01:53,640 --> 00:01:56,430
Five V-twin sessions are being used.

18
00:01:56,430 --> 00:01:57,710
So it's six.

19
00:01:57,720 --> 00:02:00,800
One is refused or rejected.

20
00:02:00,810 --> 00:02:10,610
Now here we could clear a line 98 or using the command clear line and specifying a number so it could

21
00:02:10,610 --> 00:02:12,040
say 98.

22
00:02:12,090 --> 00:02:15,610
Just to show you that again we could clear this line.

23
00:02:15,860 --> 00:02:26,740
Well we could clear the Viti why it's a clear line 98 confirm show uses 98 has been disconnected and

24
00:02:26,740 --> 00:02:32,730
now on route 1 we can telnet back to router 2.

25
00:02:33,310 --> 00:02:37,110
So we have our session on line 98.

26
00:02:37,130 --> 00:02:46,660
Reason why is when you type show line you'll see that the console is teach you why the zero the exhilarate

27
00:02:46,660 --> 00:02:56,290
port on the router is line 97 and the first Viti why he's line 98 that's to do with asynchronous modules

28
00:02:56,290 --> 00:03:01,210
that he can insert into a router which use what are called TDY lines.

29
00:03:01,570 --> 00:03:05,460
In this case I'll telnet to a physical Rodda that I've got running locally.

30
00:03:07,580 --> 00:03:12,650
And I'll log in.

31
00:03:12,690 --> 00:03:21,600
This is a 36 40 router show line shows me that I have a console as well as a lot of TDY lines.

32
00:03:21,690 --> 00:03:27,660
These allow me to implement reverse telnet sessions and then on exhilarate connection and then my Viti

33
00:03:27,660 --> 00:03:30,330
why sessions on this router.

34
00:03:30,650 --> 00:03:32,590
So show line once again.

35
00:03:32,610 --> 00:03:35,450
First line is is the console.

36
00:03:36,890 --> 00:03:42,710
Then we have a range of teach you wise then the exhilarate line and then Viti lines.

37
00:03:42,860 --> 00:03:50,930
Hence the number of these Viti waterlines is not one or two because you can have reverse console connections

38
00:03:51,320 --> 00:03:53,960
on a router in the old days.

39
00:03:53,960 --> 00:04:00,410
This was used for asynchronous modems so the early old days on routers we had asynchronous modems and

40
00:04:00,410 --> 00:04:07,460
we would connect via those modems on various TDY lines so just type show line if you if you're not sure

41
00:04:07,460 --> 00:04:10,960
what numbers are that will vary from device to device.

42
00:04:11,390 --> 00:04:22,730
So on this virtual switch show line shows me that the Sillery port is line 1 and the value line is line

43
00:04:22,760 --> 00:04:30,030
2 because it doesn't support T.T. why asynchronous modems whereas a router such as a thirty seven twenty

44
00:04:30,040 --> 00:04:31,080
five does.

45
00:04:31,490 --> 00:04:42,530
So I could also type clear line Viti Y and specify number so 0 and the connection was closed.

46
00:04:42,680 --> 00:04:43,750
So tell me back

47
00:04:46,770 --> 00:04:56,170
username is David not Siska show line shows me various lines show user uses.

48
00:04:56,340 --> 00:05:00,210
Shows me that at the moment this is the only active a y line.

49
00:05:00,210 --> 00:05:04,100
You can also see the stall associated with V-2 on line.

50
00:05:04,110 --> 00:05:06,470
The other stations would have timed out because of a timer.

51
00:05:07,320 --> 00:05:09,410
So once again if I jump back.

52
00:05:09,410 --> 00:05:17,080
Control shift 6 x another telnet session show line.

53
00:05:17,100 --> 00:05:24,760
You can see the console is active and so both these 51 lines show users.

54
00:05:24,810 --> 00:05:33,150
Shows me that I have two connections between zero and VTR I one play a line 99.

55
00:05:33,420 --> 00:05:41,250
Notice the connection was closed on this router shows sessions shows me my current sessions and then

56
00:05:41,250 --> 00:05:46,470
I could do something like disconnect which will disconnect the last active session.

57
00:05:46,470 --> 00:05:53,420
So show sessions shows me that 6 was closed.

58
00:05:53,480 --> 00:05:54,550
I could also do it this way.

59
00:05:54,560 --> 00:06:00,670
Disconnect three show sessions.

60
00:06:00,670 --> 00:06:02,140
Three is not available.

61
00:06:02,140 --> 00:06:07,990
If I want to restore session I could just simply select the connection number so one.

62
00:06:08,230 --> 00:06:10,140
But as you can see that's being closed.

63
00:06:11,970 --> 00:06:20,670
So show session two that was closed by the remote host for that was closed five that was closed.

64
00:06:20,670 --> 00:06:23,280
So I have no active sessions at the moment.

65
00:06:23,280 --> 00:06:36,100
And if I telnet it back to the router and logged in control shift 6 x Take me back show sessions select

66
00:06:36,100 --> 00:06:38,740
session 1 and notice that resumes.

67
00:06:38,760 --> 00:06:40,600
And I am now on route to.
