我正在使用我的 Ubuntu-Server 和 transmission-cli 下载种子文件。当我尝试下载 Ubuntu 12.04.5 Server 种子文件时，transmission 连接到多个对等点，但没有下载任何内容。
给定的命令是：
/usr/bin/screen -a -S rdownload_$torrent_name /usr/bin/transmission-cli -w "$target_directory" $remote_home/$torrent_name
这是（筛选后的）输出：
transmission-cli 2.52 (13304)

在下载目标中没有建立任何目录。奇怪的是，今天早些时候的另一个种子运行正常。但我没有通过屏幕启动它。对可能的原因有什么想法吗？
致谢，马库斯
答案1
现在它起作用了。我想，我知道为什么了。我曾意外地使用选项 -d 执行了 transmission-cli，但没有给出值。这可能是意味着下载速度 = 0 吗？当我给出选项 -D 时，它按预期工作。
