ssh Connection refused

虚拟机里安装了ubuntu(10.24.8.194),桥接模式,通过ssh无法连接到服务器10.24.13.200;
在主机windows(10.24.8.251)可以通过putty ssh连接到服务器(10.24.13.200);
在服务器也可以通过ssh连接到虚拟机ubuntu(10.24.8.194);
虚拟机内openssh-server/openssh-client,都已经安装,防火墙已关!
找不到原因,请大虾帮忙!

FileZilla连接失败,connection refused
本人Linux小白,望轻喷 我用visualbox配置了一台Ubuntu16.04的虚拟机,今天想用FileZilla传一些文件给虚拟机,发现连接失败。 错误信息是: ``` 状态: 正在连接 192.168.3.5... 响应: fzSftp started, protocol_version=5 命令: open "jeloys@192.168.3.5" 22 错误: Network error: Connection refused 错误: 无法连接到服务器 ``` 然后尝试了网上所说的开启ssh 和 sshd 没有用,防火墙已经关闭,iptables也已经为ssh设置好了。然后在虚拟机上使用 ``` root@jeloys-VirtualBox:~# ssh 192.168.3.4 ``` 提示: ``` ssh: connect to host 192.168.3.4 port 22: Connection refused ``` 注:宿主ip为192.168.3.4;虚拟机IP为192.168.3.5;虚拟机网络为桥接模式。 求各位大佬答疑解惑~
vscode Remote-SSH Unauthorized client refused
1、vscode通过Remote-SSH来进行远程开发,连接Linux开发环境 2、本地安装了Git,服务器起了SSH服务,key、IP、等都设置好了 3、当试图连接的时候,终端会显示“Connected to server”,但紧接着右下角通知会提示“Failed to connect to the remote extension host server (Error: Connection error: Unauthorized client refused.)” 请问怎么破??? 通过CMD SSH连接是可以的,没有任何问题

linux ssh 22 端口不通
两台ubuntu虚拟机,ip分别为192.168.244.1,192.168.244.128 通过192.168.244.128ping192.168.244.1时是通的,两台虚拟机网络没有问题,但是用telnet 192.168.244.1 22不通,ssh 192.168.244.1显示connection refused。 检查192.168.244.1机器22端口由sshd监听工作正常,iptables没有启用,求解这是怎么回事。 之前配置Hadoop时生成了ssh的非密码登录密钥,不知道是不是因为这个原因导致22端口不通。。

Hibernate链接数据库出现未见过的错误
一直使用SSH框架都很正常,前几天朋友让我当他面做个Hibernate的例子,当场就报了这个奇怪的错误。 然后再MyEclipse中调用之前写的Hibernate例子,也无法运行。 在MyEclipse的package explorer中,有好多以前写的例子,都是能顺利运行的,现在情况是SSH框架,JDBC的都可以单独运行,唯独纯Hibernate写的无法运行。 程序如下: package com.test; import java.util.Date; public class User { private int id; private String name; private Date birthday; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } } <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.test"> <class name="User"> <id name="id"> <generator class="native"/> </id> <property name="name" length="100"/> <property name="birthday"/> </class> </hibernate-mapping> hibernate.cfg.xml <?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3060/hibernatetrain</property> <property name="connection.username">root</property> <property name="connection.password">123456</property> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <property name="hbm2ddl.auto">create</property> <mapping resource="com/test/User.hbm.xml" /> </session-factory> </hibernate-configuration> 测试程序: package com.test; import java.util.Date; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; public class TestUser { public static void main(String [] args){ Configuration cfg = new Configuration(); cfg.configure(); SessionFactory sf = cfg.buildSessionFactory(); Session s = sf.openSession(); Transaction tx = s.beginTransaction(); User user = new User(); user.setName("Hoffman"); user.setBirthday(new Date()); s.save(user); tx.commit(); s.close(); } } 以上数据库链接,用户名和密码都是多次检查的,没有问题。 在Transaction tx = s.beginTransaction();这步,出现了以下错误: log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). log4j:WARN Please initialize the log4j system properly.

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...

Python十大装B语法
Python 是一种代表简单思想的语言,其语法相对简单,很容易上手。不过,如果就此小视 Python 语法的精妙和深邃,那就大错特错了。本文精心筛选了最能展现 Python 语法之精妙的十个知识点,并附上详细的实例代码。如能在实战中融会贯通、灵活使用,必将使代码更为精炼、高效,同时也会极大提升代码B格,使之看上去更老练,读起来更优雅。

JDK12 Collectors.teeing 你真的需要了解一下
前言 在 Java 12 里面有个非常好用但在官方 JEP 没有公布的功能,因为它只是 Collector 中的一个小改动,它的作用是 merge 两个 collector 的结果,这句话显得很抽象,老规矩,我们先来看个图(这真是一个不和谐的图????): 管道改造经常会用这个小东西,通常我们叫它「三通」,它的主要作用就是将 downstream1 和 downstre...
为啥国人偏爱Mybatis,而老外喜欢Hibernate/JPA呢?
关于SQL和ORM的争论,永远都不会终止,我也一直在思考这个问题。昨天又跟群里的小伙伴进行了一番讨论,感触还是有一些,于是就有了今天这篇文。 声明:本文不会下关于Mybatis和JPA两个持久层框架哪个更好这样的结论。只是摆事实,讲道理,所以,请各位看官勿喷。 一、事件起因 关于Mybatis和JPA孰优孰劣的问题,争论已经很多年了。一直也没有结论,毕竟每个人的喜好和习惯是大不相同的。我也看...

“狗屁不通文章生成器”登顶GitHub热榜,分分钟写出万字形式主义大作
一、垃圾文字生成器介绍 最近在浏览GitHub的时候,发现了这样一个骨骼清奇的雷人项目,而且热度还特别高。 项目中文名:狗屁不通文章生成器 项目英文名:BullshitGenerator 根据作者的介绍,他是偶尔需要一些中文文字用于GUI开发时测试文本渲染,因此开发了这个废话生成器。但由于生成的废话实在是太过富于哲理,所以最近已经被小伙伴们给玩坏了。 他的文风可能是这样的: 你发现,...
