How to Keep Alive SSH Sessions Many NAT firewalls time out idle sessions after a certain period of time to keep their trunks clean. Sometimes the interval between session drops is 24 hours, but on many commodity firewalls, connections are killed afte…

[ MobaXterm]设置保持SSH连接 ssh远程连接会在无操作时自动断开连接.为了保持程序运行和连接,需要设置保持连接. 1.MobaXterm如果使用了MobaXterm客户端,那么需要在设置里点选setting>SSH>sessions setting>勾选ssh Keepalive keepalive 选择下图的选项即可: 2.SSH如果使用的是ssh则需要设定超时连接的时间/etc/ssh/sshd_config: 服务器端要设置客户的超时重连:ClientAliveCou…

 Java ssh 访问windows/Linux 工作中遇到的问题: Java code运行在一台机器上,需要远程到linux的机器同时执行多种命令.原来采用的方法是直接调用ssh命令或者调用plink的命令. google下java的其他ssh方法,发现有个包. 具体介绍如下: Ganymed SSH2 for Java is a library which implements the SSH-2 protocol in pure Java.It allows one to connect…

实验目的:通过控制R1 后 , TELNET 到R2(12.1.1.2),R3(13.1.1.3)对R2,R3 进行远程管理. 在R1 上配置: R1#telnet 12.1.1.2 //从R1 TELNET 到R2 Trying 12.1.1.2 ... Open User Access Verification Password: R2> 按<Ctrl-Shift-6> + x 把界面切换回R1 R1#telnet 13.1.1.3 //从R1 TELNET 到R3 Trying 1…

ssh连接超时问题解决方案: 1.修改server端的etc/ssh/sshd_config ClientAliveInterval 60 #server每隔60秒发送一次请求给client,然后client响应,从而保持连接 ClientAliveCountMax 3 #server发出请求后,客户端没有响应得次数达到3,就自动断开连接,正常情况下,client不会不响应 2.修改client端的etc/ssh/ssh_config添加以下:(在没有权限改server配置的情形下) Serve…

一套Pike版本的openstack测试环境,使用vlan模式的网络,数据网网卡使用的是绿联的usb百兆网卡,遇到了虚拟机网络异常的问题.同一个vlan下,不同宿主机上的两台虚拟机,相互之间可以ping通,但是不能ssh. ICMP能通,说明链路没有问题,ssh走的是ssh协议,不通的话,最常见时两种情况,一种是防火墙安全组禁用了ssh的端口,经过排查,发现不是这个问题. 另一种情况可能是MTU设置错误的问题. 按照以太网早期的设计,链路层最大传输的数据的长度(MTU)最小46个字节,最大150…
