rsync：连接超时

我无法通过 rsync 列出目录：

来自 Host2：

user@host2#sudo rsync user@host1::share
rsync: failed to connect to host1: Connection timed out (110)
rsync error: error in socket IO (code 10) at clientserver.c(122) [Receiver=3.0.7]

它没有将 rsync 显示为服务

user@host2#nmap host1_IP //(IP of host1)

rsync 可以隐藏在防火墙后面吗？

答案1

如果您没有通过 ssh 使用 rsync，则需要在远程端运行 rsyncd。

对于防火墙，请确保端口 873 对 TCP 开放。

假设 /etc/services 正确，您也可以为 udp 873 打开它。

$ egrep rsync /etc/services
rsync       873/tcp
rsync       873/udp
