【问题描述】:
我正在尝试使用 Net::SSH 库来登录和管理支持 ssh 的主机。它是一种电信设备,TL1 也是如此。我似乎能够成功登录,但是当我尝试 ssh.exec 某些东西时,它中止说它无法执行命令。这是我的简单代码:
require 'net/ssh'
Net::SSH.start('10.204.121.192', 'password', :password => "password") do |ssh|
ssh.exec("INH-MSG-ALL;")
end
如果我将相同的代码指向 Linux 服务器并提供诸如“ls -l /”之类的命令,它就可以正常工作。我想知道的是,我可以使用这个 ssh 库吗?我需要使用其他命令而不是 exec 吗?
这是错误输出:
