我正在使用windows和putty ssh到vagrant virtualbox。我无法使用访问在vagrant virtualbox中运行的django服务器,我也禁用了我的防火墙,这是我的vagrant文件:
VAGRANTFILE_API_VERSION = "2"
def command?(name)
`which #{name}`
$?.success?
end
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

我试图在openstack上的VM上安装pluxio1.2,并使用spark和hdfs,但是安装不起作用。Spark和hdfs已经在安装和工作。

我已经停止使用CentOS运行上下文代理实例的虚拟机。在使用enabler重新启动系统时,后者会出现致命错误。见以下日志:

下面是一个简单的教程,该教程指导我如何使用Vagrant安装Tomcat:
vagrant init emessiha/ubuntu64-java --box-version 1.0.0
然后它告诉我编辑VagrantFile从8080转发到8080,然后做“流浪者向上”。当我运行“流浪汉”时,我会收到这样的消息:
Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening

我是新来的,并尝试了从DigitalOcean,但当我做docker run -p 5000:5000 flask_demo:v0,我得到以下错误。
码头工人:
Error response from daemon: Ports are not available: listen tcp 0.0.0.0:5000: bind: address already in use.
请帮帮我

我刚刚检查了我的一个服务器,发现它停止了对任何请求的响应。
大约2021-08-31 22:00:16.575欧洲标准时间:
Failed to connect to search.myapp.com port 443: Connection refused
在我的服务器上检查时,似乎VM实例是在一天前重新启动的(docker显示我的主容器只运行了24小时)。
这个错误会让防火墙发出尖叫声,所以我进行了双重检查,并为我的实例启用了allow-http和allow-https防火墙规则。
编辑:所以我尝试创建另一个新的VM,只运行一个简单的HTTP服务器,同样的错误,连接拒绝在:80和:443。
我用JavaFX编写了一个应用程序,我想打开一个连接到Arduino的端口:
SerialPort port = new SerialPort ("PORT");
当我打开港口时:
port.openPort ();
我遇到了以下问题(当我注释这一行代码时,问题就消失了):
# A fatal error has been detected by the Java Runtime Environment:
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000007110b5db, pid=5544, tid=73
我试图在python中使用PJSIP模块进行调用。对于SIP传输的设置,我所做的如下
trans_cfg = pj.TransportConfig()
# port for VoIP communication
trans_cfg.port = 5060
# local system address
trans_cfg.bound_addr = inputs.client_addr
transport = lib.create_transport(pj.TransportType.UDP,trans_cfg)
当我完成调用时,我将把传输设置清除为,transport = None。
