linux无显示器怎么修改密码
linux下修改用户密码的方法:1、执行【passwd 用户名】命令;2、根据提示输入新密码,回车;3、再次输入新密码,回车即可。Linux修改密码用 passwd 命令,用root用户运行passwd ,passwd user_name可以设置或修改任何用户的密码,普通用户运行passwd只能修改它自己的密码。
配电柜多功能仪表电表读如何清零
1.首先断开仪表的电源,仪表不亮。然后按住回车键的同时给仪表上电,约5s后开机界面结束后,松开回车键。2.任一电参量界面下,按SET键,显示PASS3、按回车,第三排显示数值,需输入密码00014、进入编程后,一级菜单显示SYS5、按回车进入第二排,按右键找二级菜单CLr.E6、按回车,第三排显示OK,即清零成功
freesshd密钥怎么连接
ssh通过密钥进行连接sshd服务提供两种的方法:基于口令的:经过验证帐号与密码即可登陆到远程主机。基于密钥的:需要在本地生成"密钥对"后将公钥传送至服务端,进行公共密钥的比较。使用密码验证终归会存在着被骇客暴力破解或嗅探的危险,其实也可以让ssh服务基于密钥进行(可无需密码验证),步骤如下: 1.在本地主机中生成密钥对复制代码[root@wluat ~]# ssh-keygen Generating public/private rsa key pair.Enter file in which to save the key (/root/.ssh/id_rsa): #回车或设置密钥的存储路径Created directory '/root/.ssh'.Enter passphrase (empty for no passphrase): #回车或设置密钥的密码Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa.Your public key has been saved in /root/.ssh/id_rsa.pub.The key fingerprint is:92:9e:ae:cd:eb:40:a8:7c:ad:ac:af:89:c2:ce:16:fa root@wluatThe key's randomart image is: --[ RSA 2048]---- | || || || . . || . . o S ||.o ... o || .....o ||=o .= ||=BE .o*. | ----------------- 复制代码注:这里为了ssh连接不要再输入密码,没有输入密码,而是直接回车。 2.将生成好的公钥密钥传送至远程主机:ssh-copy-id -i ~/.ssh/id_rsa.pub user@hostname复制代码[root@wluat ~]# ssh-copy-id 192.168.0.80The authenticity of host '192.168.0.80 (192.168.0.80)' can't be established.RSA key fingerprint is af:b9:dc:e7:7d:45:d7:e0:ae:24:0f:b1:a3:1f:94:48.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added '192.168.0.80' (RSA) to the list of known hosts.root@192.168.0.80's password: Now try logging into the machine, with "ssh '192.168.0.80'", and check in: .ssh/authorized_keysto make sure we haven't added extra keys that you weren't expecting.复制代码注:其是这个就相当于在服务器端建立了~/.ssh,目录,并将公钥写到了远程主机的"~/.ssh/authorized_keys"文件中,文件的权限如下:root@wls12c ~]$ ll .ssh总用量 8-rw------- 1 root root 392 8月 17 14:15 authorized_keys-rw-r--r-- 1 root root 1586 8月 17 12:01 known_hosts[root@wls12c ~]$ ll .ssh/authorized_keys -rw------- 1 root root 392 8月 17 14:15 .ssh/authorized_keys 如果是传送到远程主机的普通用户,authorized_keys的权限并不是600,需要手工修改,否则报如下错误:[root@wluat ~]# ssh weblogic@192.168.0.80Permission denied (publickey,gssapi-keyex,gssapi-with-mic). 或者手工复制公钥到认证文件:cat ~/.ssh/id_rsa.pub | ssh user@server "cat - >> ~/.ssh/authorized_keys" 3.测试,连接远程主机的效果ssh -i ~/.ssh/id_rsa user@hostname[root@wluat ~]# ssh 192.168.0.80Last login: Wed Aug 17 14:21:51 2016 from 192.168.0.150[root@wls12c ~]$已经实现了不要通过密码验证了
