更新後 tftpd-hpa 無法啟動

我安裝了 tftpd-hpa（Ubuntu 16.04 LTS）。最近，也許在獲得一些更新（或卸載一些具有大量依賴項的應用程式）後，tftpd-hpa 不再啟動。 tftpd-hpa 設定為：

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure --create"

預設根目錄是/var/lib/tftpboot.systemctl status tftpd-hpa.service和命令的輸出journalctl -xe：

testlab@Amtek:~$ systemctl status tftpd-hpa.service

編輯：下面是sudo netstat -lnp | grep 69輸出

udp        0      0 0.0.0.0:69              0.0.0.0:*                           851/inetd

答案1

結合兩部分資訊：

最近，收到一些更新後

並出現以下錯誤：

4 月 18 日 01:47:32 Amtek in.tftpd[4777]：無法綁定至本機 IPv4 套接字：位址已在使用中

問題似乎是當您啟動 tftp 伺服器時，tftp 連接埠 (69) 已被使用。這可能是由於最近安裝/更新的新程式造成的。

執行下列命令將協助您找出電腦上哪個進程正在使用 tftp 連接埠 (69)：

netstat -lnp | grep 69

網路統計人

-l, --listening 僅顯示偵聽套接字。（預設會省略這些。）

--numeric , -n 顯示數字位址，而不是嘗試確定符號主機、連接埠或使用者名稱。

-p, --program 顯示每個套接字所屬程式的 PID 和名稱。

注意：| grep 69 過濾結果，僅顯示包含 69 的行

編輯：

如您在問題中新增的結果netstat -lnp顯示，現在inetd正在 udp/連接埠 69 上運行，它可能會作為的一部分執行 tftp 用戶端inetd，因此您無法在此連接埠上執行 tftpd-hpa。

注意：請檢查是否tftpd正在運行，如果足夠好則可以避免使用tftpd-hpa

您有兩個選擇：

移動tftp伺服器以使用不同的連接埠這可以透過更改以下在連接埠 69 上設定 tftp 的行來完成：

TFTP_ADDRESS=“：69”

要使用其他端口，例如 6900：

TFTP_ADDRESS=":6900"

注意：使用此解決方案將需要tftp-client使用新的連接埠號

停止inetd使用 udp/69 您可以檢查資料夾tftp configuration中是否存在文件inetd，搜尋名稱如下的文件：

/etc/xinetd.d/tftp

或者

 /etc/inetd.d/tftp

答案2

對於使用新版本 tftpd-hpa 的人來說，它可能很有用。我的配置是：

RUN_DAEMON="yes"
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/user/tftproot"
FTP_ADDRESS=":69"
TFTP_OPTIONS="192.168.0.1 --ipv4 -m /etc/tftpd.remap --create --permissive"

如果沒有 tftpd 的伺服器位址（在我的範例中為 192.168.0.1），tftpd-hpa 服務無法啟動。
