我正在尝试运行一个命令paramiko,应该能够打开一个X窗口.我正在使用的脚本如下:

import paramiko                                    

ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect('192.168.122.55', username='user', password='password')
transport = ssh_client.get_transport()
session = transport.open_session()

session.request_x11()
stdin = session.makefile('wb')
stdout = session.makefile('rb')
stderr = session.makefile_stderr('rb')
session.exec_command('env; xterm')
transport.accept()

print 'Exit status:', session.recv_exit_status()
print 'stdout:\n{}'.format(stdout.read())
print 'stderr:\n{}'.format(stderr.read())
session.close()

不幸的是,当我运行上面的脚本时,我得到了这个输出:

Exit status: 1
stdout:
SHELL=/bin/bash
XDG_SESSION_COOKIE=8025e1ba5e6c47be0d2f3ad6504a25ee-1347286654.617967-1932974971
SSH_CLIENT=192.168.122.1 58654 22
USER=user
MAIL=/var/mail/user
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
PWD=/home/user
LANG=en_US.UTF-8
SHLVL=1
HOME=/home/user
LOGNAME=user
SSH_CONNECTION=192.168.122.1 58654 192.168.122.55 22
DISPLAY=localhost:10.0
_=/usr/bin/env

stderr:  
xterm: Xt error: Can't open display: localhost:10.0

如果我在终端中运行以下命令:

ssh -X user@192.168.122.55 'env; xterm'

然后我得到相同的环境变量(虽然有些端口发生了变化),所以我说我的环境是正确的.但是,我仍然缺少一些可以paramiko …

我有简单的TCP套接字程序,我想以10个字节的块发送字符串.服务器将加入块.但是我不确定如何将字符串拆分为二进制文件以及如何发送二进制文件块.我不想一次发送512个字节,而是多次发送10个字节.

我找到了一个可以将数据序列化为字节串(？)的模块Pickle,但是如何对此应用socket.send()？

服务器:

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(("", my_port))
server_socket.listen(5)
client_socket, address = server_socket.accept()
data = client_socket.recv(512)

客户:

message = "some string I want to send in chunks"
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect((host, my_port))
client_socket.send(message)
client_socket.close()
