In tutorial 1, connectivity not working after making some edits (although everything looked correct)

the LACONEU host professor was playing around with tutorial 1, and then the network connections weren't generated, even though all the netParams options looked ok -- I checked and the values were same as in original version. It was quite frustrating, since was impossible to figure out the reason why it didn't work.

This might be solved once we add the automated netParams validation is added.

從教學 1 開始，將原始版本與無法產生網路連線的編輯版本進行比較。檢查 netParams 選項的使用方式，並確定需要哪些驗證來揭露無效或不起作用的值。當該故障可以重現或得到解釋，且自動化的 netParams 驗證能夠清楚地回報問題時，即視為完成。
