制作OpenSSH 9.6 for openEuler 22.03 LTS的rpm升级包_openeuler升级openssh9.6-程序员宅基地
OpenSSH作为操作系统底层管理平台软件，需要保持更新以免遭受安全攻击，编译生成rpm包是生产环境中批量升级的最佳途径。本文在国产openEuler 22.03 LTS系统上完成OpenSSH 9.6的编译工作。
一、编译环境
1、准备环境
基于vmware workstation发布的x86虚拟机，最小化安装了openEuler 22.03 LTS，版本信息如下：
[root@localhost ~]# cat /etc/os-release
NAME="openEuler"
VERSION="22.03 LTS"
ID="openEuler"
VERSION_ID="22.03"
PRETTY_NAME="openEuler 22.03 LTS"
ANSI_COLOR="0;31"
[root@localhost ~]# rpm -qa|grep openssh
openssh-8.8p1-2.oe2203.x86_64
openssh-server-8.8p1-2.oe2203.x86_64
openssh-clients-8.8p1-2.oe2203.x86_64
[root@localhost ~]# ssh -V
OpenSSH_8.8p1, OpenSSL 1.1.1m 14 Dec 2021
[root@localhost ~]# sshd -V
unknown option -- V
OpenSSH_8.8p1, OpenSSL 1.1.1m 14 Dec 2021
usage: sshd [-46DdeiqTt] [-C connection_spec] [-c host_cert_file]
[-E log_file] [-f config_file] [-g login_grace_time]
[-h host_key_file] [-o option] [-p port] [-u len]
[root@localhost SPECS]# openssl
OpenSSL> version
OpenSSL 1.1.1m 14 Dec 2021

[root@localhost ~]# cp /etc/yum.repos.d/openEuler.repo{,.bak}
[root@localhost ~]# sed -i "s/repo.openeuler.org/mirrors.aliyun.com\/openeuler/g" /etc/yum.repos.d/openEuler.repo

%description
SSH (Secure SHell) is a program for logging into and executing
commands on a remote machine. SSH is intended to replace rlogin and
rsh, and to provide secure encrypted communications between two
untrusted hosts over an insecure network. X11 connections and
arbitrary TCP/IP ports can also be forwarded over the secure channel.
OpenSSH is OpenBSD's version of the last free version of SSH, bringing
it up to date in terms of security and features, as well as removing
all patented algorithms to separate libraries.
This package includes the core files necessary for both the OpenSSH
client and server. To make this package useful, you should also
install openssh-clients, openssh-server, or both.
%description clients
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package includes
the clients necessary to make encrypted connections to SSH servers.
You'll also need to install the openssh package on OpenSSH clients.
%description server
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
the secure shell daemon (sshd). The sshd daemon allows SSH clients to
securely connect to your SSH server. You also need to have the openssh
package installed.
%description askpass
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH.
%description askpass-gnome
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH and the GNOME GUI desktop
environment.

文章浏览阅读1.2k次。使用说明:开启Google的登陆二步验证（即Google Authenticator服务）后用户登陆时需要输入额外由手机客户端生成的一次性密码。实现Google Authenticator功能需要服务器端和客户端的支持。服务器端负责密钥的生成、验证一次性密码是否正确。客户端记录密钥后生成一次性密码。下载谷歌验证类库文件放到项目合适位置(我这边放在项目Vender下面)https://github.com/PHPGangsta/GoogleAuthenticatorPHP代码示例://引入谷_php otp 验证器

JS重写Date函数，兼容IOS系统_date.prototype 将所有 ios-程序员宅基地
文章浏览阅读1.8k次，点赞5次，收藏8次。IOS系统Date的坑要创建一个指定时间的new Date对象时，通常的做法是：new Date("2020-09-21 11:11:00")这行代码在 PC 端和安卓端都是正常的，而在 iOS 端则会提示 Invalid Date 无效日期。在IOS年月日中间的横岗许换成斜杠，也就是new Date("2020/09/21 11:11:00")通常为了兼容IOS的这个坑，需要做一些额外的特殊处理，笔者在开发的时候经常会忘了兼容IOS系统。所以就想试着重写Date函数，一劳永逸，避免每次ne_date.prototype 将所有 ios
