怎么上手

由 README 提炼，执行前请确认

原文

brew install upa/tap/mscp

硬件要求按 README 说明

README 未说明；仅要求远端运行支持 SFTP 子系统的标准 sshd（如 openssh-server），并能正常 ssh 登录

没人工点评？写下你的经验

多线程 scp 工具，用多条 SSH/SFTP 连接并行传多个文件或大文件，缩短传输时间

用多条 SSH/SFTP 连接并行传输文件，突破单连接带宽限制，适合大文件或跨网络批量拷贝时提速。

核心能力

多线程并行传输多个文件
单个大文件分块并行传输
用法与 scp 基本一致
支持断点续传失败中断的传输
远端只需标准 sshd 的 SFTP 子系统

容易踩的坑

从源码构建依赖打过补丁的 libssh，需先执行 git submodule update --init 并应用 patch；不支持远端到远端复制；传输目录无需 -r 选项，与 scp 习惯不同

mscp: multi-threaded scp

mscp, a variant of scp, copies files over multiple SSH (SFTP) connections by multiple threads. It enables transferring (1) multiple files simultaneously and (2) a large file in parallel, reducing the transfer time for a lot of/large files over networks.

You can use mscp like scp, for example:

$ mscp srcfile [email protected]:dstfile

Remote hosts only need to run standard sshd supporting the SFTP subsystem (e.g. openssh-server), and you need to be able to ssh to the hosts as usual. mscp does not require anything else.

https://github.com/upa/mscp/assets/184632/19230f57-be7f-4ef0-98dd-cb4c460f570d

Major differences from scp on usage:

Remote-to-remote copy is not supported.
-r option is not needed to transfer directories.
Checkpointing for resuming failed transfer is supported.
and any other differences I have not implemented and noticed.

Install

macOS

# Homebrew
brew install upa/tap/mscp

# MacPorts
sudo port install mscp

Ubuntu

sudo add-apt-repository ppa:upaa/mscp
sudo apt-get install mscp

RHEL-based distributions

sudo dnf copr enable upaaa/mscp
sudo dnf install mscp

Build

mscp depends on a patched libssh. The patch introduces asynchronous SFTP Write, which is derived from https://github.com/limes-datentechnik-gmbh/libssh (see Re: SFTP Write async).

We test building mscp on Linux (Ubuntu, Rocky, Alma, and Alpine), macOS, and FreeBSD.

# clone this repository
git clone https://github.com/upa/mscp.git
cd mscp

# prepare patched libssh
git submodule update --init
patch -d libssh -p1 < patch/$(git -C libssh describe).patch

# install build dependency
bash ./scripts/install-build-deps.sh

# configure mscp
mkdir build && cd build
cmake ..

# in macOS, you may need OPENSSL_ROOT_DIR for cmake:
# cmake .. -DOPENSSL_ROOT_DIR=$(brew --prefix)/opt/openssl@3

# build
make

# install the mscp binary to CMAKE_INSTALL_PREFIX/bin (usually /usr/local/bin)
make install

Source tar balls (mscp-X.X.X.tar.gz, not Source code) in Releases page contain the patched version of libssh. So you can start from cmake with it.
