如何跨两个 ssh 进行 scp

我有三台计算机，分别是家用计算机、工作计算机和服务器计算机，并且我通过以下方式从家用计算机连接到服务器：

ssh -t <WORKusername>@<WORK> ssh -p23456 <SERVERusername>@localhost

我需要将文件从 HOME 传输到 SERVER 但我无法将文件留在工作

此外我需要将文件从服务器传输到主目录处理完之后，该怎么办呢？

我已经看过了https://serverfault.com/questions/37629/how-do-i-do-multihop-scp-transfers和从我的（第三台）电脑在两个远程主机之间进行 scp但我无法更改 ssh 配置家机器

我已经尝试过这个，但毫无进展：

$ scp -o ProxyCommand="ssh <WORKusername>@<WORK> nc localhost" ASPEC.zip <SERVERusername>@localhost:~/
<WORKusername>@<WORK>'s password: 
This is nc from the netcat-openbsd package. An alternative nc is available
in the netcat-traditional package.
usage: nc [-46DdhklnrStUuvzC] [-i interval] [-P proxy_username] [-p source_port]
      [-s source_ip_address] [-T ToS] [-w timeout] [-X proxy_protocol]
      [-x proxy_address[:port]] [hostname] [port[s]]
ssh_exchange_identification: Connection closed by remote host
lost connection

我也尝试了以下操作，但这是从服务器到主目录传输文件的反向操作：

ssh -t <WORKusername>@<WORK> "ssh -p 23456 <SERVERusername>@localhost \"cat file.zip\""

我也尝试过 tar，但是没有用：

tar c file.zip | ssh -t <WORKusername>@<WORK> "ssh -p 23456  <SERVERusername>@localhost | tar x"
Pseudo-terminal will not be allocated because stdin is not a terminal.
<WORKusername>@<WORK>'s password: 
Pseudo-terminal will not be allocated because stdin is not a terminal.
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password).
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

然后我尝试：

# From home:
$ ssh -L 23456:<SERVERusername>@localhost:22 <WORKusername>@<WORK>

# After ssh, in WORK:
$ ssh -p 23456 <SERVERusername>@localhost

# From home:
$ scp -P file.zip <SERVERusername>@localhost:~/

当我给出 scp 命令时，我得到了这些错误，

# on WORK terminal:
channel 3: open failed: administratively prohibited: open failed

# on SERVER terminal:
ssh_exchange_identification: Connection closed by remote host
lost connection

我也尝试过 rsync，但是没有用：

rsync -e "ssh -A -t <WORKusername>@<WORK>e ssh -p23456 <SERVERusername>@localhost" file.zip :~/

我如何从家中使用 scp 将文件传输到服务器？

还有从服务器到主页吗？

答案1

尝试使用这个：

scp -P SERVERPORT -o 'ProxyCommand ssh -p WORKPORT WORKUSER@WORK nc %h %p 2>/dev/null' localfile SERVERUSER@SERVER:remotefile

ProxyCommand在连接到 SERVER:SERVERPORT 的工作主机上创建代理（请参阅数控)。 %h和%p是 ssh 变量 - 分别是目标主机和端口。

答案2

您可以尝试以下方法：

cat localfile | ssh <WORKusername>@<WORK> "ssh -p23456 <SERVERusername>@localhost 'cat > remotefile'"
