删除或修改Windows7保存的共享用户名和密码

Mon, 07 Jun 2021 10:49:42 +0800

当我们访问Windows共享目录或者NAS共享盘时，Windows会提示输入共享用户名和密码，这时如果我们选择了“记住我的凭据”，Windows就会将认证凭证保存到计算机中，这样下次再访问共享时，就不需要再输入共享用户名和密码了，方便的用户的使用。但是如果一旦共享的密码修改了，我们无法再访问共享了。

要删除或修改保存的用户凭证，我们首先从开始菜单打开Windows“控制面板”。在“控制面板”中，进入“用户帐户”子项，选择“管理您的凭据”，打开“凭据管理器”窗口。在“凭据管理器”窗口，我们就可以看到Windows保存的所有认证凭证了。

然后根据实际情况进行删除或修改就可以了。

kali 无法使用nfc的解决办法

Wed, 13 Jan 2021 15:05:13 +0800

新版本kali(2017之后的版本)无法正常使用nfc功能来破解电梯卡，其实很早就有这种情况了，只是当时没存在博客上，长时间没用自己也忘了怎么弄了，昨天又找了好多资料，才找到关键位置进行修改，现将解决方法记录下来：

从kali 2018版本以后，默认还是带mfoc软件的，只需要修改即可：

加载模块
modprobe -r nfc pn533 pn533_usb
修改黑名单列表
vim /etc/modprobe.d/blacklist-libnfc.conf
blacklist nfc
blacklist pn533
blacklist pn533_usb

今天测试2020.4版本，发现kali没有默认带mfoc软件，需要先安装才可以，有些配置默认已经修改只需要加截模块即可:

安装mfoc软件
apt-get install mfoc
加载模块
modprobe -r pn533_usb

letsencrypt无法正常更新证书的解决方法

Wed, 13 Jan 2021 12:07:03 +0800

由于从国内部分地区无法正常访问raw.githubusercontent.com域名，导致certbot-auto程序更新失败，无法完成域名证书更新。报如下错误：

/data/letsencrypt/letsencrypt-auto renew
/data/letsencrypt/letsencrypt-auto has insecure permissions!
To learn how to fix them, visit https://community.letsencrypt.org/t/certbot-auto-deployment-best-practices/91979/
Upgrading certbot-auto 1.9.0 to 1.11.0...
Couldn't download https://raw.githubusercontent.com/certbot/certbot/v1.11.0/letsencrypt-auto-source/letsencrypt-auto. <urlopen error [Errno 111] Connection refused>

现给出两种解决方法：

不更新certbot-auto程序，直接更新域名证书。
在命令行后面增加 --no-self-upgrade，例如：
/data/letsencrypt/letsencrypt-auto renew --no-self-upgrade
修改hosts文件，完成certbot-auto程序更新。
编辑hosts文件：
vim /etc/hosts
增加如下一行：
199.232.4.133 raw.githubusercontent.com
保存退出
：wq

Cacti 时间筛选bug 导致无法筛选指定时间段内的图形的解决办法

Wed, 14 Oct 2020 09:32:03 +0800

Cacti 0.8.7至1.2.10所有版本都可能出现此问题，原因是源码中写死了一个时间戳：1600000000 也就是2020/9/13 20:26:40，超过这个时间的cacti便会无法放大图形，无法筛选等。

解决办法：
找到站点目录下：
graph_xport.php 和 cp graph_image.php 这2个文件，保险起见可以先备份一下，然后查找 1600000000 ，将此数字改为将来的一个时间，比如：2000000000

代码片段如下：

if (!empty($_GET[“graph_end”]) && $_GET[“graph_end”] < 2000000000 )

保存就可以了，无需重启

windows10远程桌面提示“出现身份验证错误。要求的函数不受支持”

Wed, 17 Jun 2020 09:56:50 +0800

win10远程时如果报错“出现身份验证错误。要求的函数不受支持”，按以下方法操作即可正常使用。

按windows+r打开运行提示框，输入regedit，点击确定，打开注册表编辑器；找到路径：HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters（后两项没有时手动建立，右键左侧目录System，选择“新建——项”，输入文件夹名），在Parameters 里新建 DWORD（32位），名称：“AllowEncryptionOracle”，值：2；再次连接远程计算机，
