配置Solaris允许SSH远程登录

Oracle Solaris 10操作系统安装完成后，默认配置下，不允许root通过SSH登录系统。下面是小编收集整理的配置Solaris允许SSH远程登录，希望对大家有帮助~~

配置Solaris允许SSH远程登录

工具/原料

Solaris 10

方法/步骤

1) 配置/etc/ssh/sshd_config的PermitRootLogin参数

#

# gedit /etc/ssh/sshd_config

# cat /etc/ssh/sshd_config

# Copyright (c) 2001, 2010, Oracle and/or its affiliates. All rights reserved.

#

# ident "@(#)sshd_config 1.10 10/10/19 SMI"

#

# 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.

# IPv4 only

#ListenAddress 0.0.0.0

# IPv4 & IPv6

ListenAddress ::

# Port forwarding

AllowTcpForwarding no

# If port forwarding is enabled, specify if the server can bind to INADDR_ANY.

# This allows the local port forwarding to work when connections are received

# from any remote host.

GatewayPorts no

# X11 tunneling options

X11Forwarding yes

X11DisplayOffset 10

X11UseLocalhost yes

# The maximum number of concurrent unauthenticated connections to sshd.

# start:rate:full see sshd(1) for more information.

# The default is 10 unauthenticated clients.

#MaxStartups 10:30:60

# Banner to be printed before authentication starts.

#Banner /etc/issue

# Should sshd print the /etc/motd file and check for mail.

# On Solaris it is assumed that the login shell will do these (eg /etc/profile).

PrintMotd no

# KeepAlive specifies whether keep alive messages are sent to the client.

# See sshd(1) for detailed description of what this means.

# Note that the client may also be sending keep alive messages to the server.

KeepAlive yes

# Syslog facility and level

SyslogFacility auth

LogLevel info

#

# Authentication configuration

#

# Host private key files

# Must be on a local disk and readable only by the root user (root:sys 600).

HostKey /etc/ssh/ssh_host_rsa_key

HostKey /etc/ssh/ssh_host_dsa_key

# Length of the server key

# Default 768, Minimum 512

ServerKeyBits 768

# sshd regenerates the key every KeyRegenerationInterval seconds.

# The key is never stored anywhere except the memory of sshd.

# The default is 1 hour (3600 seconds).

KeyRegenerationInterval 3600

# Ensure secure permissions on users .ssh directory.

StrictModes yes

# Length of time in seconds before a client that hasn't completed

# authentication is disconnected.

# Default is 600 seconds. 0 means no time limit.

LoginGraceTime 600

# Maximum number of retries for authentication

# Default is 6. Default (if unset) for MaxAuthTriesLog is MaxAuthTries / 2

MaxAuthTries 6

MaxAuthTriesLog 3

# Are logins to accounts with empty passwords allowed.

# If PermitEmptyPasswords is no, pass PAM_DISALLOW_NULL_AUTHTOK

# to pam_authenticate(3PAM).

PermitEmptyPasswords 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 no

PermitRootLogin yes

# sftp subsystem

Subsystem sftp internal-sftp

# 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

# Rhosts RSA Authentication

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts.

# If the user on the client side is not root then this won't work on

# Solaris since /usr/bin/ssh is not installed setuid.

RhostsRSAAuthentication no

# Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication.

#IgnoreUserKnownHosts yes

# Is pure RSA authentication allowed.

# Default is yes

RSAAuthentication yes

2) 重启SSH服务，使配置生效

# svcadm restart ssh

3) 重启系统

可能需要重启Solaris后，root才可以远程登录。

# reboot

44) 远程登录
