    Hi,

    I'm trying to make an ssh connection from one AIX LPAR to another AIX LPAR but not successful. The detail output of the command is shown below:

    I've tried to find files /etc/host.allow and /etc/host.deny files to make appropiate enteries but unable to find then. We are using AIX 5.3.

    another FAQ that would be great if anyone of the forum administrators could put into a separate FAQ page....

    -> you find the reason in the sshd_server log

    Trying to Find sshd_server log files in /var/log directory but unable to find. Actually when I create the user on both servers and try to make an ssh connection, it works fine but when I create RSA key and then tried to do either scp or ssh. First it show that connection lost and then shows that connection is closed by remote server. I'm not an AIX Administrator. So kindly help in resolving this Issue.

    ... then you go make friends with the aix administrator and ask him to look in the sshd_server log.
