| Requirement | Description |
|---|---|
| A user account | - The minimum requirement is a non-root user account. |
| - Arctera requires privileged access to discover some information. You can use privilege control software to designate privileged access to a specific user for specific commands. See Commands that require the root access for agentless discovery of UNIX hosts . See Using the privilege control software with agentless discovery of UNIX hosts . | |
| Network access between hosts | Ensure there is network access between the host that you want to discover and Arctera InfoScale Operations Manager Control Host that performs discovery. |
| UNIX agentless discovery requires contacting SSH running on TCP port 22 on the remote host. TCP port 22 should be open in both directions between the Control Host and the remote host. | |
| A shell on the remote host | Arctera InfoScale Operations Manager requires a shell on the remote host (sh, ksh, or bash) that accepts sh file redirection. |
| Secure Shell (SSH) on the remote host | To communicate between the Arctera InfoScale Operations Manager host and remote UNIX hosts, Arctera InfoScale Operations Manager uses the non-keyboard interactive, password-based authentication of SSH. |
| Ensure that: | |
| - SSH is installed. The SSH package is typically installed by default; however, it may not be present if a minimal operating system installation was performed. If the SSH package is not present, use the operating system installer to install SSH, or download and install OpenSSH. See About installing OpenSSH on a UNIX host . | |
| - SSH is set up properly. See SSH configuration requirements for agentless discovery . | |
| - OpenSSH is not version 0.9.8e or 0.9.7e on AIX, Linux, and Solaris hosts. These versions have known AES encryption issues, which can cause a warning. |
