Solaris[TM] 9 & 10 Operating System: Controlling SSH Connections

(Doc ID 1017514.1)

Last updated on JULY 29, 2016

Applies to:

Solaris Operating System - Version 9 GA to 10 9/10 U9 [Release 9.0 to 10.0]
All Platforms

Goal

The sshd daemon that comes with the Solaris[TM] 9 & 10 Operating System uses TCP (Transmission Control Protocol) Wrappers (also called "libwrap") to control
access to hosts.

(Unlike other systems, Solaris 9 & 10 does not use the OpenSSH
keywords "AllowHosts" and "DenyHosts" to permit or prevent SSH [Secure
Shell] connections.)

TCP wrapper support is compiled into the sshd binary and sshd, which runs
as a standalone daemon. (Unlike other services, the Solaris 9 & 10 Operating
System Secure Shell daemon is not under the control of inetd and tcpd.)

If sshd is running, and if the wrapper access control files are present
and correctly configured, you have all that you need to control host
access. This article explains how to do this.
