    # 開源家用網路環境 {%hackmd @coscup/announcement-2025 %} > 請從這裡開始 ###### tags: `COSCUP2025`, `zhtw`, `elementary` 開始前將提供直播連結與ppt by frakw PPT URL: https://shlink.frakw.work/coscup_2025_ppt YouTube 直播存檔: https://youtu.be/2CRczyjgx4s COSCUP 官方錄影: https://youtu.be/CosZLoVITLQ ## 講者會後補充說明 因為當下有點趕而且緊張 所以有些重點忘記講到 在此補充給大家 `2025-08-12` * 任何有網路 + 儲存空間 + 外部存取機制 的裝置或系統都能作為NAS,那些專門的NAS系統,就是在這些基礎上加入 如: 網頁管理介面, 備份功能, API 等額外功能,所以我認為有除錯能力的人都可以自己組裝, 安裝NAS系統 (其實就跟你平時安裝系統差不多哦~) * UPS的功用其實不是拿來在停電時讓電腦繼續運作,而是給電腦足夠的時間 "正常" 關閉服務與關機,突然斷電導致的關機可能導致系統崩潰(需要重灌)或是硬碟損毀,另外UPS通常自帶突波保護功能 可以在電力不穩時保護電供 * wifi mesh vs wifi 漫遊(k/v/r) : Wi-Fi Mesh 主要是用來擴大覆蓋範圍,並集中管理多個節點,它不是 Wi-Fi 標準,而是各家廠商的自家實作,通常會內建一些終端切換的輔助機制。但「自動切換」本身是終端裝置的功能,傳統多 AP 也有,只是速度與體驗可能不如配合 802.11k/v/r 標準。Wi-Fi 漫遊(k/v/r)是 IEEE 標準,重點是讓終端在 AP 之間切換時更快、更順。如果家中每層樓都有有線骨幹,其實買支援 k/v/r 的多 AP 系統就夠,不一定要購買昂貴的 Mesh 套裝。 * pikvm 就是一個開源DIY版, 便宜版的IP-KVM, 主要用途是在電腦系統崩潰後強制重開機,或是定時開關機,輸入你伺服器的螢幕輸出與輸出鍵盤滑鼠到伺服器就能使用BIOS,在網頁介面中能夠上傳裝系統的.iso,所以就能遠端重灌系統,有這個基本上就達成幾乎全遠端的配置,非常實用 ## Why opensource? - 不會受限於大公司的服務(e.g: google, youtube) - 不需要使用訂閱的服務,使用自架服務節省成本 ## Router >主要介紹:OpenWRT ### Router Security Issue - 路由器漏洞時常出現,修都修不完 - 開源的可以被社群監督 - 不怕被塞backdoor ### Flash OpenWRT into your router - 選擇越簡單的機器做入門(查看OpenWRT的官方文件) - 一般可以直接用OpenWRT刷進去router就好,有些要用CH314安裝 ## NAS - 選擇 openmediavault (OMV): debian based - SMB/NFS 等 linux 支援之功能 - Docker - NextColoud : 類 google drive - Emby : 類 Plex ## Hypervisor - Proxmoc VE (PVE) - ZFS: Raid, snapshot ## Access From Wan - DDNS + Port Forwarding (Not Recommand) - CF tunnel: Bring your own domain - VPN: - ZeroTier - Tailscale - Exit node ## Trouble Shooting - PiKVM based on Raspberrypi - UPS ## Self hosting service - Bitwarden - vaultwarden - mattermost - RustDesk - Zipline - etc...
