永豐 shioaji api 一直登入失敗 ValueError

 一開始學習就充滿挫折~

裝好shioaji套件後，最一開始就是先登入，在這關就卡三天，找到網路上一些教學，也有官方出的PDF檔文件，結果登入後都很怪，雖然有session up的字眼出現，但又有產生其他錯誤。

登入後常會看到這兩種錯誤訊息

ValueError: The seed must be exactly 32 bytes long或ValueError: Invalid character '0'

後來又在官網上在仔細查看，發現了一小段重要的說明，就是以前登入的帳號密碼，是跟下單軟體一樣，用身份證字號去登入，但現在api的登入帳號密碼已經不同了。

是要先去永豐金理財網這個網站，登入後裡面有個API管理的功能，新增一組系統自動產生的超長帳號跟密碼來搭配api登入，程式碼也跟舊的不太一樣，可以參考官網的教學 https://sinotrade.github.io/zh_TW/tutor/login/  

照網站教的，api登入就成功了，不會有那些奇怪的錯誤訊息。

永豐 shioaji 無法安裝

 在python裡要安裝永豐API要用的一個套件shioaji時，一直失敗，就找不到這個套件。

後來才發現，這個套件不支援自己電腦內的python3.11版。

所以就要另外裝一個python舊版的環境，目前測試是在3.8跟3.9都可以裝。

Anaconda 建立不同版本python環境

 最近在學Python，是直接去下載Anaconda來安裝，裝好後就有Python可以使用。

平常在寫程式是，是利用裡面已經有的SPYDER或是Jupyter notebook，在裡面編寫程式跟執行。

但最近要下載一個套件，在目前使用的Python版本裡不支援，需要用比較舊的Python才行。

這時Anaconda就有個很好用的功能，就是它可以產生不同的虛擬環境。

Anaconda剛裝好的時後，就會有預設的一個環境，搭配當下一起安裝好的Python。

如果想要用改的版本的Python，可直接建立另一個虛擬環境，選擇不同版本的Python就行了。

這時SPYDER或是Jupyter notebook還是會用預設的Python版本在執行，所以就要做一下調整。

詳細方法可以參考這篇，寫的很仔細。

Recently, I've been learning Python by downloading and installing Anaconda. Once installed, Anaconda provides a Python distribution that I can use.

When writing code, I typically utilize the built-in IDEs like Spyder or Jupyter Notebook that come with Anaconda. I write and execute my code within these environments.

However, I recently needed to download a package that is not supported by the current version of Python I'm using. I needed an older version of Python for compatibility.

This is where Anaconda's useful feature comes in: it allows the creation of different virtual environments.

By default, Anaconda creates an environment with the Python version that was installed at that time.

If I want to use a different version of Python, I can simply create another virtual environment and choose the desired Python version.

In this case, Spyder or Jupyter Notebook will still use the default Python version for execution, so some adjustments need to be made.

fortigate 外到內 政策沒用

 在fortigate的防火牆上，外到內的部份有設兩條政策

政策1:外部特定IP->內部ALL->全部服務==>封鎖

政策2:外部特定IP->內部特定主機->全部服務==>封鎖

結果這個外部特定IP居然沒有在政策1就被封鎖，而是在比對到政策2時才封鎖，非常奇怪，詢問廠商才得知設定上有個地方有特別注意。

在設定外對內的政策時，因為有些內部主機有提供對外服務，有使用虛擬IP(VIP)這個功能，所以外對內的政策，內部是指定ALL的情況下，需要透過指令模式，在這個政策上加一個set match-vip enable，這個封鎖到透過VIP連進來的外部主機。

這就是為何第1條政策無效，但第2條有效的原因。

On the Fortigate firewall, there are two policies defined for inbound traffic from the outside to the inside network:

Policy 1: External specific IP -> Internal ALL -> All services ==> Block

Policy 2: External specific IP -> Internal specific host -> All services ==> Block

However, it was discovered that the external specific IP was not blocked by Policy 1 but was blocked when matched with Policy 2, which seemed strange. Upon contacting the vendor, it was revealed that there was a particular setting that required attention.

When configuring the inbound policies from external to internal, there were internal hosts that provided services to the outside using Virtual IP (VIP) functionality. Therefore, in the case where the internal field is set to ALL, an additional command "set match-vip enable" needs to be added to this policy in command mode. This command ensures that external hosts connecting through VIP are also blocked.

This explains why Policy 1 was ineffective while Policy 2 remained effective.

WIN10 在EDGE 用IE模式開網頁

 有些網頁必須要用IE才能正常顯示，如果透過EDGE，就要啟用裡面的IE模式才行。

可以直接在EDGE設定中加入要用IE模式開起的網頁，但這有個缺點，要一台一台做，而且還有期限，預設30天，最長可以改到90天，不適合在公司裡這樣設定。

這時就可以用GPO來佈署，步驟如下:

1. 確認GPO裡有EDGE設定，因為DC都是2012版的，所以要自己下載ADMX檔來增加EDGE功能，方式可參考 https://www.anoopcnair.com/download-microsoft-edge-admx-group-policy-templates/

2. GPO裡有EDGE設定後，要啟用兩個設定

設定企業模式網站清單-這個先設定好檔案路徑跟檔名，例如

C:\ielist.xml，這個檔案在第3步會產生。

再來是要啟用設定InternetExplorer整合。

3. 安裝Enterprise Mode Site List Manager，透過這個檔案把要用IE模式開啟的網站建成一個xml的清單，取名成ielist.xml，派送到使用者電腦C槽中，跟第2步GPO裡的設定配合。清單的設定方式一樣網路上很多教學，可參考https://www.anoopcnair.com/configure-enterprise-mode-site-list-using-intune/

4.上述都設定好後，GPO佈署下去就ok了。

當用EDGE開啟IE模式的網站，看一下網址例左邊有出現一樣IE的檔案，就表示現在已在IE模式下執行，設定成功。

Using IE Mode to Open Websites in EDGE on Windows 10

Some websites require Internet Explorer (IE) to be displayed correctly. If you're using EDGE, you can enable the built-in IE mode to access these websites. While you can manually add websites to open in IE mode within EDGE settings, this method has its drawbacks. It requires configuring each device individually and has a time limit, typically set to 30 days (extendable up to 90 days), which is not ideal for company-wide settings.

To address this, you can deploy the settings using Group Policy Objects (GPO) with the following steps:

1.Ensure that the GPO includes the EDGE settings. Since the domain controllers are running the 2012 version, you'll need to download the ADMX files to add EDGE functionality. You can refer to the following link for the process: link to download ADMX files.

2.Once the EDGE settings are available in the GPO, enable two specific settings:

3.Configure the Enterprise Mode Site List: Set the file path and name, for example, C:\ielist.xml. This file will be generated in the next step.

Enable the Internet Explorer Integration setting.

Install the Enterprise Mode Site List Manager. Using this tool, create an XML list named ielist.xml that contains the websites to be opened in IE mode. Place the file in the C:\ directory of users' computers and align it with the settings from step 2. There are various tutorials available online on how to configure the list. You can refer to this link: link to configure Enterprise Mode Site List using Intune.

4.Once all the settings are configured, deploy the GPO to the desired devices.

To verify if a website is opened in IE mode using EDGE, check the URL. If you see the IE file icon on the left side, it indicates that the website is being accessed in IE mode, confirming the successful configuration.

win虛擬機無法正常運作 開機出現錯誤 0xC0000017

 今天把一台esxi的虛擬機做還原後，開機出現錯誤，錯誤代碼是0xC0000017，還說什麼系統檔案可能有錯誤，安全模式或回複到上次正常啟動都沒用。

最後就進設定看，發現，記憶體設定只有16m，好小啊，調成16g後，就可以正常開機了，虛驚一場。

Unable to Boot Win Virtual Machine - Error 0xC0000017

Today, after restoring a virtual machine on ESXi, I encountered an error during the boot process. The error code was 0xC0000017, indicating a possible issue with the system files. I tried starting in Safe Mode and even attempted to revert to the last known good configuration, but none of these options resolved the problem.

In a final attempt to troubleshoot, I accessed the settings and discovered that the memory allocation was set to a mere 16MB. It was a surprisingly low value. After adjusting it to 16GB, the virtual machine was able to boot up successfully. It turned out to be a false alarm, and the issue was resolved.

2022年最後一個月選擇權交易

 今年基本上就是慘，前11個月，好像只有一個月是有獲利，其他都賠錢。

12月開始把交易條件訂的比較高，所以交易次數不多，雖然前兩週都只做1口單賣當沖，但至少都有賺，第三週目前確定是沒交易機會了，希望剩下兩週也能順一點，至少讓我最後一個月也是獲利結束今年，把希望寄託在明年。

SQUID Proxy無法連線內部https網站-NONE/503 0 CONNECT

 用SQUID架好Proxy Server後，都蠻順利的，開網站，用LINE，SKYPE等外部的程式都正常。

但要開啟內部的https網站時，就會無法顯示，錯誤訊息會說"網頁可能暫時離線，或是已經遷移到另一個網址"。

在access log裡查到的紀錄都是 "NONE/503 0 CONNECT"。

然後就開始上網到處查，然後有看到有些人提到在squid.conf 裡要加入一行"dns_v4_first on"，雖然感覺這跟我的問題不相關，但就試試吧。

結果在conf裡先搜尋dns的字眼時，看到了這段，"dns_nameservers  8.8.8.8 208.67.222.222"。

DNS居然是指向外部，所以就把內部的DNS SERVER IP加到最前面，重啟服務，就解決這個問題了。

SQUID Proxy Unable to Connect to Internal HTTPS Websites - NONE/503 0 CONNECT

After setting up the SQUID Proxy Server, everything seemed to be working smoothly. Websites loaded fine, and external applications like LINE and Skype functioned properly. However, when trying to access internal HTTPS websites, they would not display, and an error message stating "The webpage might be temporarily down or may have moved to a new address" would appear.

Upon checking the access log, the recorded entries were "NONE/503 0 CONNECT."

I started searching online for a solution and came across a suggestion to add the line "dns_v4_first on" to the squid.conf file. Although it didn't seem directly related to my issue, I decided to give it a try.

While searching for the term "dns" in the configuration file, I came across the following line: "dns_nameservers 8.8.8.8 208.67.222.222."

To my surprise, the DNS servers were pointing to external addresses. So, I added the IP address of the internal DNS server to the beginning of the list, restarted the service, and the problem was resolved.

QNAP TS-432XU(4.3.6)更換故障硬碟

 一台QNAP TS-432XU(4.3.6)有4顆硬碟做RAID5，最後一顆硬碟已出現警告建議更換，雖然還可以用，但這顆硬碟的讀寫速度慢很多，所以影響到一些日常作業。

原本同型號的硬碟停產了，所以就買一個同廠牌同容量，但轉速更快的來換。

雖然知道是熱插拔，但一開始還上網看一下是不是要在管理介面上做什麼操作，後來查到的畫面又跟自己的不同，就決定直接插拔更換了。

插上後系統就自己在重建了，蠻方便的，剩下就讓它跑完重建程序了。

Replacing a Faulty Hard Drive on QNAP TS-432XU(4.3.6)

On a QNAP TS-432XU(4.3.6) device with a RAID 5 configuration using four hard drives, the last drive started showing warning signs and advised replacement. Although it was still functional, its read and write speeds had significantly decreased, affecting daily operations.

Since the original model of the hard drive was no longer available, I purchased a higher-speed drive from the same manufacturer with the same capacity as a replacement.

While I knew that the device supported hot-swapping, I initially checked online to see if there were any specific actions required through the management interface. However, the instructions and screenshots I found were different from what I encountered, so I decided to proceed with a direct replacement.

Once I inserted the new drive, the system automatically initiated the rebuilding process. It was quite convenient, so I allowed it to complete the rebuilding procedure.

QNAP NAS無法發信 Failed to send a test message using SMTP Service.

在QNAP NAS設定好電子郵件設定，用來發送警告信給管理者，設定好後測試，卻都失敗，錯誤訊息就是示"Failed to send a test message using SMTP Service."。

從不同網段連到QNAP的管理web都正常，所以就覺得網路設定都沒問題。

後來就想用ssh連上QNAP，去ping在不同網段的mail server，卻是不通的，然後再執行route -n 顯示路由表時，卻沒有0.0.0.0的路由，這就妙了。

本來想直接用指令去加，但查到的指令route add default gw 192.168.24.1 br0有錯誤，所以就決定回管理web上看看是不是少設了什麼。

結果發現了一個東西，有一個系統預設閘道的設定，之前都沒去理它，後來進去這設定，在把gateway設定上去之後，回到ssh裡，route -n 顯示路由表時，就有0.0.0.0的路由，發送信件的功能也就正常了。

The QNAP NAS is unable to send emails.

When setting up the email configuration on the QNAP NAS to send alert messages to the administrator and testing it, all attempts fail with the error message "Failed to send a test message using SMTP Service."

Since accessing the QNAP management web interface from different networks works fine, it is believed that there are no issues with the network settings.

Later on, an attempt was made to connect to the QNAP using SSH and ping the mail server in a different network segment, but the connection was unsuccessful. Upon executing the command "route -n" to display the routing table, it was noticed that there was no route for 0.0.0.0, which was puzzling.

Initially, there was a plan to manually add the route using the command "route add default gw 192.168.24.1 br0," but it was found to be incorrect. Therefore, the decision was made to go back to the management web interface and check if anything was missing.

As a result, it was discovered that there was a default gateway setting that had been overlooked. Previously, it had not been addressed. After accessing this setting and configuring the gateway, upon returning to the SSH session and executing "route -n" to display the routing table, the route for 0.0.0.0 appeared, and the email sending functionality started working correctly.
