Telnet via console port

Hi
Is it possible to telnet via console port to a server without any additional hardware? I understand that an ip needs to be configured but i am not sure how it is to be done.
any help given is appreciated..
thanks

Yes , you can but your server must see server that you want to access first
first you can ping to server that you want to access . if you can't see it ,that is impossible to access it .

Catalyst switch hangs when connecting via console port

Hi,
I've just started work for a company - they have no network documentation or knowledge of their current set-up whatsoever.
For the LAN in the office they have Cisco Catalyst WS-C3524-XL switches. But it doesn't seem like these are even configured with an IP address for management purposes.
So, I thought I would connect via a console cable to have a look at their configurations and also to investigate some performance problems some users were having on the LAN.
BUT - when I connected to the console cable, all the switch LEDs stopped flickering happily and went solid and everyone in the office lost their network connectivity! (I wasn't popular!)
Rebooting the switch with the console port still connected had no effect - the LEDs remained solid and there was no network connectivity. However, when I removed my console cable, everything started working again!
Does anyone have any ideas a) what can have caused this and b) how I can resolve this problem and connect to the switches without disrupting all the other users!
Note: I subsequently connected to a spare WS-C3524-XL switch using the same laptop and same console cable without any problems.

Hi,
thanks for the response.
no, I can't login to the switch(es) at all. There seems to be no response from hyperterminal at all. (Then I noticed that the LEDs had gone "solid" and that everyone started to complain they had lost network connection!)
Even when I powered off and powered on the switch with the console port still connected, nothing appeared on the hyperterminal screen.
However, as mentioned, I'm able to connect to one of our spare switches using the same settings, same laptop, and same console cable - so I guess that would rule these things out as being the cause?
Its definitely a strange one, especially as it seems to be affecting all 3 of the live switches!

Terminal Adapter (Telnet) to Console Port Server?

Has anyone been able to connect to a device on a console port server?
Problem: the telnet session needs a crlf to be sent upon initial connect in order to trigger the device to send its login prompt. CPO cannot see the prompt and therefore times-out waiting for it to arrive
Thanks
Mike

We've found quite a few flavours of behaviour in ConsolePort servers. Some require crlf, others don't, while some require a password before it gives you access to the requested device. The CNOAS team has just produced a console port server workflow that presents a real time web page showing activity across ports, auto-recognition of devices etc., and allows user-written CPO provisioners and configurators to be launched to service the device. Please drop me an email for more info

Console port blocked

Can't log in via console port on the router.
In config:
line con 0
transport input none
I can remove this but if I reboot it's back there.
Solved it once but can't remember how I did it.
Thanks,
Peter

Hi,
Try doing:
conf t
line con 0
login
password [your_password]
Test access to the console port first and then remeber to "copy run start" after making changes to write any changes you have made to NVRAM
There are other ways and better ways to configure console access but this should get you going.
There is also a link here that explains some more detail

Aaa console telnet via radius

Using this configuration to radius control console and telnet access :aaa authentication login default group Sts-radius local
aaa authorization exec default group Sts-radius local
aaa accounting exec default start-stop group Sts-radius
In wlse I've configured :
diagonale@Sts-radius:aaa-server user
aaa-server user diagonale password <encrypted>
aaa-server user xxx password <encrypted>
attributes =
cisco-avpair = shell:priv-lvl=15
service-type = login
The resultat:
user fr231662 can log via console or telnet as required.
user diagonale cannot connect via telnet as required, but CAN connect via console.
I wish to NOT allow diagonale to connect via console.
How can I do that ??
Thanks

Hello,
what does the configuration of con 0 look like ? In order for RADIUS (or the local database as the backup) to authenticate console access, the config should be (here, a specific list named CONSOLE is used, in order to distinguish that this is for console access):
aaa authentication login CONSOLE group Sts-radius local
line con 0
password cisco
login authentication CONSOLE

Can not administer Catalyst 2960 switch via console

Hello,
I want to configure my switch via console cable, the switch boots up normally, and there are no configurations present on the switch. However, anything I type does not appear on the terminal client. I used several terminal clients (TeraTerm, PuTTY, HyperTerminal), all latest versions as well as different PCs. I even forced the switch to rommon mode, still, anything I type does not appear on the terminal client.
Here's the output of TeraTerm:

Is It possible connect two router**from console port to console port

Hi,
I need this for doing reverse telnet.
Thanks very much

No
you can connect router 1's aux port to router 2's console port.
line aux 0
password blablabla
login
modem InOut
transport input all
find the aux port's line number which depends on the router model then telnet to a live ip on router 1 on that port.
Worc_3640#sh line
Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int

129 AUX 9600/9600 - inout - - - 0 0 0/0 -

so say 10.1.1.100 2129 if 10.1.1.100 is on that box.

OOB management with console port

I would like to do the setup according to the doc - http://www.cisco.com/en/US/tech/tk801/tk36/technologies_tech_note09186a00800941c9.shtml
The only disadvantage I see is from the following excerpt from the article -
"Warning: Unprotected modems should not be connected to the console port. The console ports do not log users off when the carrier detect is lost, which can leave a security hole. To avoid this, use a secure modem, or connect via the AUX port. For more information on the advantages and disadvantages of connecting a modem to the Console port, refer to the Modem-Router Connection Guide."
I know I could set an exec-timeout of 1 minute but that would still leave a small window of time for security breaches if the line drops.
Could someone tell me a particular modem that has a password built into it to overcome this problem? What is the best security practice in this case?
I have setup modems before on the aux port, but you cannot access the router after reload if it boots into ROMMON mode for some reason.
Thanks,
RJ

Hi,
As a workaround you can try using an old junk PC with 2 serial ports, install Linux on that PC, connect via terminal session using the modem attached to serial COM1 (modem in autoanswer mode just like you're doing now), login with username/password on the Linux machine and then use a terminal emulation software like Minicom to open serial port COM2 to get the IOS prompt from the router.
Maybe this option is too much hassle for your application, but it won´t cost you a dime and is not really that difficult.
Regards.

Console port not working.

Hello!
I would like to know if there's some situation what a console port could be disabled, or something like that.
I'm trying to configure a Catalyst 2960 Series PoE-24 by the console port using the hyperterminal, but it's not working. I verified the cable and the COM port, and everything works with another switch (same model).
Does anyone knows what could possibly be happening?

My colleagues have focused on the usual issues that cause the console to not work - possible issues with the terminal emulator or more likely is mis match in the speed setting of the console. If you work through those possibilities and the console still does not work then I have another possibility to suggest. Perhaps someone configure the command no exec under line con 0. This would cause the console to not work. It would display messages during bootup but would not accept any commands.
Does the switch seem to boot up normally? Was it configured with an IP address that you could potentially telnet to? This would give you a way to investigate the configuration.
If my suggestion is correct and the issue is that no exec was configured then you should be able to use password recovery to bypass the existing config and this could restore normal operation for the switch.

No AAA authentication on Console port

I would like to configure our routers to use our ACS server for authentication and enable authorization for all telnet access but not use the ACS when connected to the console port. I was able to get the router configured so that console username and password access was local. However, when I attempt to go into enable mode from the console port the router still goes after the ACS server for the enble password. How do I get around this?

--begin ciscomoderator note-- The following post has been edited to remove potentially confidential information. Please refrain from posting confidential information on the site to reduce security risks to your network. -- end ciscomoderator note --
Thanks this does help. However, I'm still running into and issue. My ultimate goal is to have all users authenticate and get enable access through our ACS server based on there corporate NT domain username/pw. If the ACS server is unavailable go to the local data base. This is working fine for user telneting to the routers and also works for the console port (if the ACS server is unavailable).
However, with the ACS server active, when I console in I authenticate based on the local database admin/cisco. But when I attempt to go into enable mode the router still goes after the ACS server for a password. I would like console port users to always use the local enable password.
I'm just trying to protect myself from a possible misbehaved ACS server.

Noise on console port

I noticed a number of failed console port logins in our tacacs logs from a couple of remote routers. In both cases the usernames are gibberish - random characters in one case; access-list logs in the other.
logging in to these 2 routers (both 870s)I can see a lot of noise on the console ports. Anyone know what could be causing this?

SRW2008MP - Can't access console port

Hi, I have just purchased a used SRW2008MP that I can't configure.
I suspect that the default IP Address has been changed, so I'm trying to get in via the console port.
Unfortunately, I don't have the original console cable, so I'm not sure of the port pin-out.
Can someone please confirm the 9 pin D connector pinout for me please ?
I assume that a standard straight or null-modem cable is not suitable for this purpose ?
regards
Dave

Dave,
Very nice! I have not seen a breakout box in years. I must admit, I'm a little jealous. Please be sure any adapters being used are straigh through with your VOM.
The next part of the equation is that you must set your hyperterm connection up for this device. I should have mentioned this earlier, but I certainly did not suspect you would have access to a "cable" that fast. Set your line speed for 38400 8,N,1 with no hardware flow control. Please be certain that you are using the correct COM port, and that it does in fact work.
Keep me posted,
Christopher

ConnectionNotFoundException when connecting via serial port

Hi all
I have got a HttpConnection that looks like this
HttpConnection connection = (HttpConnection)Connector.open( "http://localhost:80/test/read.txt" );
InputStream inputstream = connection.openInputStream();
...The above codes work fine on the emulator, but when I wish to connect to the server via the device from the usb cable, it throws me an javax.microedition.io.ConnectionNotFoundException
I'm working on a SE W880i and is running the midlet from the Device Explorer...

Hi,
thanks for the response.
no, I can't login to the switch(es) at all. There seems to be no response from hyperterminal at all. (Then I noticed that the LEDs had gone "solid" and that everyone started to complain they had lost network connection!)
Even when I powered off and powered on the switch with the console port still connected, nothing appeared on the hyperterminal screen.
However, as mentioned, I'm able to connect to one of our spare switches using the same settings, same laptop, and same console cable - so I guess that would rule these things out as being the cause?
Its definitely a strange one, especially as it seems to be affecting all 3 of the live switches!

Unable to access console port

Hi,
have you access to the MSFC?
I don't understand the problem, but this maybe could help you:
