raspberry pi 4用家討論區

噚晚pi 3 a+ 殼同heatsink送到，不過個殼冇透氣窿，密冚熱度會高過冇殼，大概50C, 但靚仔好多



Pi 3 a+ 適合做Audiophile, 由於冇RJ45, 玩volumio setup要咁
https://forum.volumio.org/volumio-rpi-t11825.html

如果做raspbian headless server, 就只係flash完mirco sd咭，喺boot度開番ssh同寫番WiFi嘅config就得

部 pi 3 a+跑呢幾樣嘢, 128GB mirco sd咭, 成個成本

pi 3 a+ 198
mirco sd咭 100MB/s 107
殼 45
heatsink 40 (可有可無, 不過買個日以為pi 4b咁熱買埋,測試之後我話唔使用

電源求其搵個5V2A(最好2.5A)就得, 我用拖版USB嘅叉電位

運行嘅嘢就係proxy, file sharing同bt box, openvpn只用嚟連接nordvpn bt, 冇起server

系統資訊, 運作良好,穩定

有冇人試過攞黎做 moonlight client streaming pc game 打機

ssh玩掃雷



bash script嚟, 輸入

wget https://raw.githubusercontent.com/feherke/Bash-script/master/minesweeper/minesweeper.sh 下載, 之後 chmod +x minesweeper.sh就得

唔會啩? 我有啲VPS得128MB ram, 由於係OpenVZ虛擬技術, 冇得開swap file, 跑OpenVPN同shadowsocks-libev成十幾個用戶都冇問題

headless server只係跑吓proxy, bt, file sharing, 應該夠用, 開多個512MB swap, 好穩陣

咁就唔知了, 好似shadowsocks-libev呢啲socks5 proxy, 好少 ram已經可以處理幾百個連接, 我睇過幾MB ram就做到, 所以佢官網都教點限制

Security Tips
For any public server, to avoid users accessing localhost of your server, please add --acl acl/server_block_local.acl to the command line.

Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user:

# Up to 32 connections are enough for normal usage
iptables -A INPUT -p tcp --syn --dport ${SHADOWSOCKS_PORT} -m connlimit --connlimit-above 32 -j REJECT --reject-with tcp-reset

之前又試過係3B+ 裝steam link, 不過係揀game 畫面 係咁閃, 唔知係咪要update 曬所有嘢先😅

重用緊Jessie, 幾個server 係入面唔敢亂嚟

o係pi 3a+ 裝o左個 text rss reader - newsbeuter, 算OK, 就係i10n冇正體中文, 得殘體, 可能係冇乜正體中文用家.....

內文正體中文字有一兩粒字出唔到, 唔知係咪terminal問題?

巴打你用咩distro?

raspbian lite

sudo mount -o uid=nobody,gid=nogroup .........................
咁樣得唔得?

RPi 3 用嚟收ads-b

我估要改owner ,
sudo umount /mnt/XXXXX
chown -R pi:pi /mnt/XXXXX

如果係用NFS , /etc/exports 要有類似咁

*(rw,all_squash,insecure,async,no_subtree_check,anonuid=1000,anongid=1000)

pi@headlesspi:~ $ echo $UID
1000
要對應番, 我冇auth, 限制內網device用

另外如果係用raspbian 或者係 raspbian 衍生版本, 用WIFI o既, 要關閉佢個自動熄WIFI慳電功能,如果唔係耐o左冇流量會斷開同router WIFI 連接, 輸入

sudo /sbin/iw wlan0 set power_save off

之後

sudo nano /etc/rc.local

o係 exit 0 之前加番落去, 咁每次boot機就會自動執行

_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

/sbin/iw wlan0 set power_save off #加o係呢o度
exit 0

想玩呢個好耐
想問下ads-b係咪是但買 用佢跟既天線就可以？

係呀 但係基本上 tv dongle 得返淘寶有得買


你如果想收到好啲嘅 要喺淘寶買 1090Mhz天線

咁你之後再加 raspberrypi-ui-mods?
定係其他UI嚟？

唔係 pi4b安裝正常raspbian桌面版本, pi3a+係headless嘅, 靠ssh入去操作, 所以安裝raspbian lite就得

以前用3b+做headless有裝過VNC server嘅, 太lag實際用唔掂, 就算用1024*768 16bit color, 開firefox/chromium都係lag得好緊要, 而家唔會再搞VNC server直到raspi硬件做得唔lag先

自膠，見到個play store logo了
以為你個cap screen最出面係raspbian lite

Chromebook嚟, 有debian terminal

想買個raspberry pi 4玩吓, 去邊度買好?
argon40送貨要等勁耐

rsonline?
