Question

我的远程主机是Ubuntu。我的意图是以非root用户身份运行一些sudo命令（例如：ip route add＆lt;＆gt;）。这是我的代码片段：

def add_route_in_extrtr(rtrip,route,nexthop,action='add',ostype='ubuntu',user='test',pwd='test123'):
    """
    Adding Routes in ExtRtr(Ubuntu)
    """
    env.host_string = rtrip
    env.user = user
    env.password = pwd
    env.sudo_user = user
    if action == 'add':
            sudo("echo hello")
            sudo("ip route add %s via %s" %(route,nexthop),pty=False)
    if action == 'update':
            sudo("ip route del %s" %(route))
            sudo("ip route add %s via %s" %(route,nexthop),pty=False)

现在调用上面的函数时，我一直看到下面的失败：

[172.28.184.38] sudo: echo hello

Aborting.

在Ubuntu服务器上，我按照Fabric sudo执行的方式运行cmd，它会抛出上述错误。

test@ext-rtr:~$ sudo -S -p 'sudo password:'  -u "test"  /bin/bash -l -c "ip route add 55.55.55.0/24 via 1.102.1.254"

此外，路由不存在于linux路由表中。我在调用此函数之前检查了

根据'sudo'源代码和文档，我找不到我可能遗漏的东西。我通过挖掘stackoverflow存档尝试了一些帮助，但无法通过此失败。任何帮助，或者如果你能指出我错过了什么/做错了什么，非常感谢

python fabric sudo不尊重env.password
