Pinned topic Instalation problems (Permission denied) - Big Insights Version 2.1.0.0

‏2013-07-15T16:11:47Z |

Hi all,

I'm having problems to install biginsights-basic-linux64_b20130531_1113 (Version 2.1.0.0), please see below the error:

I tried a workaroudn already, but it did not work properly. A website gave me a suggestion to edit the file: sshd_config and add the user: biadmin as the AllowUser, but as I said it did not work.

P.S I extrated the file + issued the comand ./start.sh as a root user. Regarding to "Passwordless secure shell (SSH) screen", I choose the option:

-> Use the root user. Select this option if the following statement is true:

- You can provide the password for the root user.

....

Please advise.

Thanks in advance!

    Hello 

    I assume you should have double checked you were using correct password. So lets move on, it looks like the sshd_config denied the connection of root SSH, could you please attach the file content of /etc/ssh/sshd_config ? Most concerning part is

    AllowUsers is either commented out or contains root user in the list

    PermitRootLogin is either commented out or yes

    An workable configuration example is 

    PermitRootLogin yes

    AllowUsers biadmin root

      YangWeiWei,

      The PermitRootLogin was set to NO! I have just changed it to YES and now the instalation is progressing.

      Thank you for your help!
