    Posted 03-04-2024 07:57:00 AM

    Hi Team

    I have list of delphix engines in the config file, but when I run the command for all to check connections, its not working and its giving the error message.


    D:\Users\kartmuthyala\Downloads\dxtoolkit2>dx_connection_check -all
    Option hostip and port are required.
    Usage:
         dx_connection_check  [ -engine|d <delphix identifier> | -all ] [ -configfile file ] -hostip IP/FQDN -port portno [ --help|? ] [ -debug ]

    Arguments:
        Delphix Engine selection - if not specified a default host(s) from
        dxtools.conf will be used.

        -engine|d Specify Delphix Engine name from dxtools.conf file
        -all Run script on all engines
        -hostip IP/FQDN Host IP or FQDN
        -port portno Port to check

    Options:
        -help Print this screen
        -debug Turn on debugging


    D:\Users\kartmuthyala\Downloads\dxtoolkit2>

    Not sure whats the issue, could you please check and assist the right command to use?

    Hello Karteek,

    The help screen states that "Option hostip and port are required".

    This command is designed to test connectivity between a given Delphix Engine (or all of them in the config file) and the specified host/IP & port combination.

    EXAMPLES
        Check if listener port is open

         dx_connection_check -d 53 -hostip 192.168.1.20 -port 1521
         Connection to 192.168.1.20:1521 refused - port closed

        Check if ssh port is open

         dx_connection_check -d 53 -hostip 192.168.1.20 -port 22
         Connection to 192.168.1.20:22 sucessful - port seems to be opened

    Thanks,

    Neal

    Hi Neal

    Thank you for your response, but its not working for me.

    D:\Users\kartmuthyala\Downloads\dxtoolkit2> dx_connection_check -d 53 -hostip 10.xxx.55.22 -port 1521
    Can't find 53 in config file.
    Can't connect to Dephix Engine 53


    D:\Users\kartmuthyala\Downloads\dxtoolkit2> dx_connection_check -d 2 -hostip 10.xxx.55.22 -port 1521
    Can't find 2 in config file.
    Can't connect to Dephix Engine 2


    D:\Users\kartmuthyala\Downloads\dxtoolkit2> dx_connection_check -d 53 -hostip 10.xxx.55.22 -port 22
    Can't find 53 in config file.
    Can't connect to Dephix Engine 53

    I tried removing the no 53, not sure from where you got the 53. but I replaced with different numbers from our config file. but still its did not worked. 
    we have around 4 servers, I wanted to test connection all at a time. please suggest.

    Hi Karteek,

    "53" comes from the help command output. It would mean that in this example, there was an engine named "53" in the "dxtools.conf" file. Please try using a name that exists in your own "dxtools.conf" file. See the help output for more details:

    % ./dx_connection_check --help
    SYNOPSIS
         dx_connection_check  [ -engine|d <delphix identifier> | -all ] [ -configfile file ] -hostip IP/FQDN -port portno [ --help|? ] [ -debug ]

    DESCRIPTION
        Check connectivity between Delphix Engine and host using a specified
        port

    ARGUMENTS
        Delphix Engine selection - if not specified a default host(s) from
        dxtools.conf will be used.

        -engine|d Specify Delphix Engine name from dxtools.conf file
        -all Run script on all engines
        -hostip IP/FQDN Host IP or FQDN
        -port portno Port to check

    OPTIONS
        -help Print this screen
        -debug Turn on debugging

    EXAMPLES
        Check if listener port is open

         dx_connection_check -d 53 -hostip 192.168.1.20 -port 1521
         Connection to 192.168.1.20:1521 refused - port closed

        Check if ssh port is open

         dx_connection_check -d 53 -hostip 192.168.1.20 -port 22
         Connection to 192.168.1.20:22 sucessful - port seems to be opened

    Hi Karteek

    To run dx_connection_check against all engines in your dxtools.conf file, use the flag -all

    eg:

    ./dx_connection_check -all -hostip <host-ip-to-test> -port <port-to-test>

    Cheers

    Hi Karteek,

    It looks like one of the engines is returning an unexpected response so it gives "Engine responded with unknown state.".

    What version of dxtoolkit are you using ( ./dx_connection_check -v)?

    Can you rerun the command with the "-debug" flag?

    dx_connection_check -all -hostip 10.5.xx.200 -port 22 -debug

    Thanks,

    Neal

    Hi Karteek,

    It doesn't look like the "dx_connection_check" command catches/handles this error. I would recommend clicking on the green "New issue" button on the following link and raise a bug:

    When you raise the bug, use the "-debug 2" flag to provide the additional details that the dxtoolkit engineers will need to investigate it.

    Thanks,

    Neal

    Hi Neal, sure thank you. I will do that, till that I can check the connection individually. But how about Masking engines to check similar to VE engines? is there any DXM command for the Masking engines to check?

    I tried in DXM toolkit, no where I found.

    Hi Karteek,

    Can you start a new topic/thread about the masking engine question? The masking engine has its own set of APIs and toolkits, etc.

    It might be confusing to the community to start talking about a different tool here.

    Thanks,

    Neal

    Hello 

    I have checked with my setup and command is working fine when we are proving the correct IP or hostname and Port.

    I can see above error when we pass invalid IP address

     ./dx_connection_check -d ENGINENAME -hostip 10.61.222.663 -port 22
    Engine responded with unknown state. Please check below:
    $VAR1 = undef;
    $VAR1 = undef;

    I suggest you to check the IP with ping command once or please validate the IP or you can provide the hostname instead of IP

    Hello,

    I think Pankaj may be onto the issue.

    If you run the command with "-debug 2" and provide an IP address that the Delphix Engine can't reach, you can see the underlying problem:
