Did not receive expected response to conf t command!

betrachter over 11 years ago

Hi again! As you requested, I've made a new theme with my question. What kind of diagnostics you need from me?

I have the same question as flexible, I have 2 Cisco IOS switches 2960 (first firmware version is 12.2(50)SE5 and another 12.2(58)SE2) when I am trying to use "Device.CLI.Send commands" in Cat tools the switch, which have 12.2(50)SE5 version make all commands correctly, but when running activity on another(12.2(58)SE2): "Did not receive expected response to command: conf t" and after that Cat tools stops activity. I used putty(ssh2) as a terminal in cattools.

P.S. I apologize for my English, if something not right written^^

Thanks!

Very surprising that one of your devices is failing to execute 'conf t' command.
Have you tried a manual PuTTY session to the device using the same credentials for the device as you have specified in CatTools? What happens? Can you run the command or do you get the same error?
The only thing I can think is maybe you are not in 'enable' (privileged exec) mode for this device when trying to execute the 'conf t' command.
In the Options tab of the Device.CLI.Send Commands activity, have you selected the 'Enter command in enable mode' option?
If not then try that and see what happens, as if this works I will be able to tell you what the problem is.

Steve

Steve, "conf t" command is just an example... on 12.2(58)SE2 cattools couldn't do any command!!!!!!!!!! manualy i can do any command and it will work! in my opinion it because cattolls couldn't work with 12.2(58)SE2 firmware! Because all commands work on switches with 12.2(50)SE5 firmware.I have cattools 3.3.4 enterprise.

Still sounds very odd. I don't remember any issues with specific IOS versions not sending commands, although v3.3.4 is quite an old version now (2008). My thought therefore is its possible CatTools is either having issue trying to log in to the device, or when trying to determine the device hostname which is then used as the anchor-point when running commands to tell CatTools the command output has completed. Are there any errors in the 'Info Log' pane which provide any indication of the problem?
If you have a spare machine somewhere that can get Telnet/SSH connectivity to the problem device, you may want to try downloading the latest CatTools release Eval version to install on that test machine to see if the latest release encounters the same issue.
Failing that we'd really need to get some diagnostics from you (device DebugLog for one of the effected devices, the Infolog.txt file to cross-reference any log messages and probably also a PuTTY session log file too).
As the debuglog file may contain sensitive (login credentials) data, I'd recommend raising a support ticket for this one.
Please post back on the thread with the case number and any solution that support provide as this could be valuable for other CatTools users if they encounter a similar issue.
When you raise your support ticket, mention that you have spoken with me on thwack.
Regards.

If i correctly understand, I couldn't raise a support ticket, because i'm not yet an owner of cattools?(The v3.3.4 i get for free...just for testing) I tried a new trial version - the same situation. I'm intersted in purchasing new cattools, but it doesn't work with new cisco firmware. You also asked for some diognostics - where i need to send it?
Best regards,

You understand correctly. In order to raise a support ticket, you need to have valid (current) software maintenance for the product.
However, seeing as you are experiencing the same problem with the Evaluation download for v3.7.0, I would recommend contacting the Sales team to let them know the details.
Kind regards,
Steve

Thank you, Steve!
I will try.
But one more question: how to contact the Sales team?

About mid-way down the page: http://www.solarwinds.com/company/contact.aspx
There are different contact numbers depending on which geographical region you are in, else use the email link.
Let Sales know you are evaluating the product and are encountering this issue.

I had a problem with not getting responses or failures with CatTools waiting for an echo of a command. I had to write custom section in my scripts to send commands and only look for the command itself. The reason is because some older switches or routers for that matter will change how the prompt looks. See CatTools expects to see this hostname# for enable and hostname( for the config prompt. Well I've had some devices that shorten the hostname take "thisisareallylonghostname" the switch will shorten to say thisisareallylong# or thisisareallylon( now as you can see CatTools will never get the expected response. So below is a function I wrote for sending a command.
'######################################################################################################
' Function: Send_Command
' Purpose: This is used throughout the script to send a specific cli command.
' Variables: Command in string format, Boolean on prompts, true for Yes AND false for No
'######################################################################################################
Function Send_Command(sCommand,bYesToPrompts)
    ' Integers
    Dim i,j
    Dim iTimeOut
    Dim iChoices

    ' Booleans
    Dim bRetVal
    Dim sResponse,sBufferBefore,sBufferMore
    'Arrays
    Dim aMult(7)

    aMult(1) = "]?"
    aMult(2) = "[confirm]"
    aMult(3) = "[yes/no]"
    aMult(4) = "% Unknown command"
    aMult(5) = "% Invalid input"
    aMult(6) = "#"
    aMult(7) = "<--- More --->"
    iTimeout = 30
    iChoices = 7
    j = 0

    ' This will send the commands. This is to help on making the code smaller. Just basic commands, no responses
    Send_Command = True
    bRetVal = ""
    sResponse = sCommand
    If Len(sCommand) > 20 Then sResponse = Left(sCommand,20)
    ' Save buffer before. This helps in controlling possible issues.
    sBufferBefore = cl.RXBuffer
    ' Flush Receive Buffer

                    Exit Function
                End If
        End Select
    Loop
End Function
My function looks for the first 20 characters of a command to see if it exists in the Buffer. If it does then it will send a return character. Login to you device and whats the device hostname and how does it compare to the enable and config prompts.
