• Solaris 10 ftp,telnet,ssh,sendmail


    1. 管理命令 svcadm (服务状态管理,启动、停止等)
    # svcs <br>查看当前所有的服务状态,可以使用|管道符重定向作更个性化的查找;如
    # svcs |grep online 查看当前运行服务
    # svcs |grep offline 查看当前停止服务
    # svcs |grep inetd 查看inetd服务状态

     

    2. solaris 10 关闭ftp、telnet、sendmail
    #svcadm disable svc:network/ftp
    #svcadm disable svc:network/telnet
    #svcadm disable svc:network/smtp:sendmail

    3. Solaris 修改root 可以Telnet 与ftp
    这几天安装了Solaris 10 安装完后发现不可以用root telnet 与 ftp ,
    修改 /etc/default/login把CONSOLE=/dev/console该行注释掉,就可以用root telnet 。
    /etc/ftpd/ftpusers,如果有root,行首加#号注释掉就可以了。


    4. Solaris 10开启SSH服务

    Solaris在安装完毕后就提供了该项服务:OpenSSH
    服务的开启方法:
    svcadm enbale -rt ssh
    默认情况下,OpenSSH是禁止root帐户通过SSH方式登录的,以保障安全。
    方法如下:
    修改 /etc/ssh/sshd_config文件,将其中的“PermitRootLogin no”修改为“PermitRootLogin yes”,再执行 svcadm restart ssh 重新启动SSH服务。

    5. 启动FTP或查看FTP状态

    默认FTP是关闭的,启动命令:

    # svcadm enable /network/ftp

    此时查看FTP服务状态:

    # svcs -l network/ftp

    默认情况下,root用户无法登录,需要修改/etc/ftpd/ftpusers文件,把root那行前面加个#注释掉就可以了。

     

    6. 重启SSH

    默认SSH是开启的。但是root用户无法登录,需要修改/etc/ssh/sshd_config,把里面的 PermitRootLogin改为 yes,再重启ssh服务,

    重启命令:

    # svcadm restart network/ssh

    7. 重启网卡

    以前修改/etc/hosts文件的IP后都是通过重启机器来使设置生效的,现在也可以通过下面的命令让它生效,无需重启机器。

    # svcadm restart physical

    8. 如何重新启动sshd服务

    # ps -ef | grep ssh    查询ssh状态

    root 516 1 0 Dec 27 ? 0:00 /usr/lib/ssh/sshd

    root 2006 1728 0 09:52:49 pts/3 0:00 grep ssh

    # kill -9 516     终止ssh

    # /usr/lib/ssh/sshd   启动ssh

     

    9.

    注释掉/etc/default/login其中CONSOLE=/dev/console 一行,root就可以telnet:

     

    # more /etc/default/login
    #ident  "@(#)login.dfl  1.14    04/06/25 SMI"
    #
    # Copyright 2004 Sun Microsystems, Inc.  All rights reserved.
    # Use is subject to license terms.

    # Set the TZ environment variable of the shell.
    #
    #TIMEZONE=EST5EDT

    # ULIMIT sets the file size limit for the login.  Units are disk blocks.
    # The default of zero means no limit.
    #
    #ULIMIT=0

    # If CONSOLE is set, root can only login on that device.
    # Comment this line out to allow remote login by root.
    #
    #CONSOLE=/dev/console

    # PASSREQ determines if login requires a password.
    #
    PASSREQ=YES

    # ALTSHELL determines if the SHELL environment variable should be set
    #
    ALTSHELL=YES

    # PATH sets the initial shell PATH variable
    #
    #PATH=/usr/bin:

    # SUPATH sets the initial shell PATH variable for root
    #
    #SUPATH=/usr/sbin:/usr/bin

    # TIMEOUT sets the number of seconds (between 0 and 900) to wait before
    # abandoning a login session.
    #
    #TIMEOUT=300

    # UMASK sets the initial shell file creation mode mask.  See umask(1).
    #
    #UMASK=022

    # SYSLOG determines whether the syslog(3) LOG_AUTH facility should be used
    # to log all root logins at level LOG_NOTICE and multiple failed login
    # attempts at LOG_CRIT.
    #
    SYSLOG=YES

    # SLEEPTIME controls the number of seconds that the command should
    # wait before printing the "login incorrect" message when a
    # bad password is provided.  The range is limited from
    # 0 to 5 seconds.
    #
    #SLEEPTIME=4

    # DISABLETIME  If present, and greater than zero, the number of seconds
    # login will wait after RETRIES failed attempts or the PAM framework returns
    # PAM_ABORT. Default is 20. Minimum is 0. No maximum is imposed.
    #
    #DISABLETIME=20

    # RETRIES determines the number of failed logins that will be
    # allowed before login exits. Default is 5 and maximum is 15.
    # If account locking is configured (user_attr(4)/policy.conf(4))
    # for a local user's account (passwd(4)/shadow(4)), that account
    # will be locked if failed logins equals or exceeds RETRIES.
    #
    #RETRIES=5
    #
    # The SYSLOG_FAILED_LOGINS variable is used to determine how many failed
    # login attempts will be allowed by the system before a failed login
    # message is logged, using the syslog(3) LOG_NOTICE facility.  For example,
    # if the variable is set to 0, login will log -all- failed login attempts.
    #
    #SYSLOG_FAILED_LOGINS=5
