不能使用面料 - 是否需要任何服务器配置？

Question

我正在使用fabric机架空间服务器远程部署我的应用程序.我在家用计算机上使用相同的操作系统(Ubuntu Server 10.04)在虚拟机上尝试过我的脚本,它们似乎都可以工作.

奇怪的是,所有put结构命令都在真实服务器上失败.所有其它命令(run,cd,sudo等),似乎工作正常.

这只在针对此特定服务器时发生,这是我执行的命令:

fab test --host remote-server

remote-server是我的别名.ssh/config.我的fabfile:

@task
def test():
    sudo("echo testing")
    put("/tmp/file.txt", "/tmp/")

tmp/test_file.txt 只是我用于测试的文本文件

这是输出

[remote-server] Executing task 'test'
[remote-server] sudo: echo testing
[remote-server] out: testing

我需要在远程服务器上配置什么才能使用put？

感谢@Drake我发现sftp远程计算机上的服务器存在问题.

为了测试这个:

$ sftp remote-server
subsystem request failed on channel 0
Couldn't read packet: Connection reset by peer

我读到这是为了启用sftp我需要添加该行

Subsystem sftp /usr/lib/openssh/sftp-server

to /etc/ssh/sshd_config和restart(/etc/init.d/ssh restart)ssh服务.但是这条线已经存在并且无法正常工作.

然后,在阅读http://forums.debian.net/viewtopic.php?f=5&t=42818之后,我改变了那一行

Subsystem sftp internal-sftp

重新启动该ssh服务,它现在正在工作:

$ sftp remote-server
Connected to remote-server
sftp>
