[ubuntu][tftp] ubuntu tftp setup - openbsd-inetd tftp tftpd

在 Ubuntu 上安裝 tftpd 伺服器是一件非常簡單的事，首先執行以下這個指令安裝需要的套件：

sudo apt-get install tftp tftpd openbsd-inetd

然後再執行以下的指令啟動 openbsd-inetd：

sudo /etc/init.d/openbsd-inetd start

nano /etc/inetd.conf

tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /home/freeman/tftp

(/home/freeman/tftp change what folder you want)

基本上，這樣就可以使用 tftpd 了。不過，由於 Ubuntu 的 openbsd-inetd 預設將 tftpd 的路徑指定為 /srv/tftp，我覺得有點不大方便，因此通常習慣再去修改 /etc/inetd.conf，將 /srv/tftp 修改成 /tmp/tftproot，這樣一來，我也不用再去理會 /srv 這個目錄的權限，只要將要藉由 tftp 傳送的檔案直接複製到 /tmp/tftproot 目錄就行了，更方便許多呢！
