asrock Q1900m-itx VGA輸出電路的電阻被挖掉

asrock Q1900m-itx 手殘去挖到黃色部位，然後vga就不顯示了(但os抓得到vga也能顯示hdmi)，這是黃色這邊少了甚麼零件嗎？三個顏色都沒了，會不會是把水平同步或是垂直同步弄壞了

RGB信號分別由[0,7.14V]間的電壓代表顏色值，

這邊的大大都好厲害 ，給的答案快速又正確，昨天用電表量一下 左邊電阻下方與VGA第14PIN導通，阻值1K，上方到VGA 14 Pin阻值11K，所以貼片電阻就是10K，右邊下方與VGA第13PIN導通，阻值1K，估計上面再接一個10K電阻就行了，不過礙於功力，我直接在這導通，然後在VGA線上動手腳，在13 PIN的蕊線裡串一個10K的水泥電阻應該也是可行吧?

10.29 Slow HTTP Denial of Service Attack (Slowloris)

站長日誌 109.10.29 弱點掃描偵測到Slow HTTP Denial of Service Attack弱點一隻 Server-Specific Recommendations Applying the above steps to the HTTP servers tested in the previous article indicates the following server-specific settings: Apache Using the < Limit > and < LimitExcept > directives to drop requests with methods not supported by the URL alone won’t help, because Apache waits for the entire request to complete before applying these directives. Therefore, use these parameters in conjunction with the  LimitRequestFields ,  LimitRequestFieldSize ,  LimitRequestBody ,  LimitRequestLine ,  LimitXMLRequestBody  directives as appropriate. For example, it is unlikely that your web app requires an 8190 byte header, or an unlimited body size, or 100 headers per request, as most default configurations have.  Set reasonable  TimeOut  and  KeepAliveTimeOut  directive values. The default value of 300 seconds for  TimeOut  is overkil...

在CentOS 8 Stream安裝NTP Client與設定時區

sudo dnf install chrony vi /etc/chrony.conf 加入 server tock.stdtime.gov.tw sudo systemctl enable chronyd sudo systemctl start chronyd sudo timedatectl set-timezone Asia/Taipei date ls -l /etc/localtime 在Fortigate設定NTP自動校準時間 Use this command to configure Network Time Protocol (NTP) servers. The Network Time Protocol enables you to keep the FortiGate time in sync with other network systems. By enabling NTP on the FortiGate, FortiOS will check with the NTP server you select at the configured intervals. This will also ensure that logs and other time-sensitive settings on the FortiGate are correct. The FortiGate maintains its internal clock using a built-in battery. At start up, the time reported by the FortiGate will indicate the hardware clock time, which may not be accurate. When using NTP, the system time might change after the FortiGate has successfully obtained the time from a configured NTP server. config system ntp set ntpsync {enable | disable} Enable/disable setting the Forti...
