kb74: Unix\Linux collections fail to register

Please see the requirements below if collections fail to register when you add the Unix application:

1. The computer must support SSH or rexec access. If SSH is not enabled, then rexec is used.
   Note: Some SSH implementations may prohibit root from logging in to the system directly. You can use a non-root account to collect Unix metrics in most cases.
2. If you configure Longitude to collect statistics from the computer as root, the computer must not be configured to disallow remote access as root.
3. AIX computers may require host name resolution for the Longitude agent monitoring them. You may need an entry in the /etc/hosts file on the AIX server for the Longitude agent.
4. Longitude collections make use of sysstat utilities (iostat, sar, mpstat, etc). If sysstat is not installed on the managed device, the application will fail to register.
5. For Linux, sysstat 6.0.2 through 7.0.1 is supported. You can determine the version of sysstat on Linux, by using the -V flag with the sysstat commands (e.g. sar -V)
6. Some versions of SUSE Linux disable password authentication for SSH. To enable password authentication, edit /etc/ssh/sshd_config to change:
   PasswordAuthentication no
   to:
   PasswordAuthentication yes
   After making the edit, restart the ssh daemon.
