首先，找到/etc/ssh/sshd_config文件，找到PermitRootLogin那行。看看该关键字后面跟的是“yes”，还是“no”。“yes”代表允许非本机使用ssh访问Solaris；“no”代表不允许非本机通过ssh访问Solaris服务器。
其次，把“yes”、“no”修改为预期要修改的结果。
最后，用命令“svcadm restart ssh”重启服务就可以了。
操作代码如下：
bash-3.00# grep PermitRootLogin /etc/ssh/sshd_config
PermitRootLogin no
bash-3.00# vi /etc/ssh/sshd_config

# Configuration file for sshd(1m)
# Protocol versions supported
#
# The sshd shipped in this release of Solaris has support for major versions
# 1 and 2. It is recommended due to security weaknesses in the v1 protocol
# that sites run only v2 if possible. Support for v1 is provided to help sites
# with existing ssh v1 clients/servers to transition.
# Support for v1 may not be available in a future release of Solaris.
#
# To enable support for v1 an RSA1 key must be created with ssh-keygen(1).
# RSA and DSA keys for protocol v2 are created by /etc/init.d/sshd if they
# do not already exist, RSA1 keys for protocol v1 are not automatically created.
# Uncomment ONLY ONE of the following Protocol statements.
# Only v2 (recommended)
Protocol 2
# Both v1 and v2 (not recommended)
#Protocol 2,1
# Only v1 (not recommended)
#Protocol 1
# Listen port (the IANA registered port number for ssh is 22)
Port 22
# The default listen address is all interfaces, this may need to be changed
# if you wish to restrict the interfaces sshd listens on for a multi homed host.
# Multiple ListenAddress entries are allowed.
/PermitRootLogin no
# To disable tunneled clear text passwords, change PasswordAuthentication to no.
PasswordAuthentication yes
# Use PAM via keyboard interactive method for authentication.
# Depending on the setup of pam.conf(4) this may allow tunneled clear text
# passwords even when PasswordAuthentication is set to no. This is dependent
# on what the individual modules request and is out of the control of sshd
# or the protocol.
PAMAuthenticationViaKBDInt yes
# Are root logins permitted using sshd.
# Note that sshd uses pam_authenticate(3PAM) so the root (or any other) user
# maybe denied access by a PAM module regardless of this setting.
# Valid options are yes, without-password, no.
PermitRootLogin yes
# sftp subsystem
Subsystem sftp /usr/lib/ssh/sftp-server
# SSH protocol v1 specific options
#
# The following options only apply to the v1 protocol and provide
# some form of backwards compatibility with the very weak security
# of /usr/bin/rsh. Their use is not recommended and the functionality
# will be removed when support for v1 protocol is removed.
# Should sshd use .rhosts and .shosts for password less authentication.
IgnoreRhosts yes
RhostsAuthentication no
