The configuration of vswitches and vrouters is impossible for you to use hardware. what I bring to you today is a small experiment.You can perform an experiment on the Huawei MA5200G simulator.For specific commands and explanations, I have all written my friends who wish to cook the same dishes with me! First, I have collected some basic commands for vswitches.Common commands:PCA login: root; Use root UserPassword: linux; password: linux# Shutdown-h now; shutdown# Init 0; Shutdown# Logo

route table is as follows: # Route [add | del] [-net |-host] target [netmask Nm] [gw Gw] [[dev] If] Where: * Add: add a routing rule. * Del: delete a routing rule. * Net: the destination address is a network. * Host: the destination address is a host. * Target: target network or host * Netmask: network mask of the destination address * Gw: Gateway used to route

using the route command, after the machine is restarted or the NIC is restarted, the route becomes invalid. Method: // route reference added to the host # route add-host 192.168.1.11 dev eth0 # route add-host 192.168.1.12 gw 192.168.1.1 // route reference added to the network # route add-net 192.168.1.11 netmask route 255.255.255.0 eth0 # route add-net 192.168.1.11 netmask 255.255.255.0 gw 192.168.1.1 # ro

Recent small mess I use the Ansible batch deployment device access to the log audit system, after the discovery of script execution, the log server side still did not receive the Linux host upload syslog, after troubleshooting the cause of the failure is that the host route is not put throughTo add a route to a host, the instructions are simple:1.

the document DOC1,DOC3,DOC5. After the index is built, the system will automatically generate The following dr$myindex$i,dr$myindex$k,dr$myindex$r,dr$myindex$x,mytable5 tables (assuming the table is MyTable, indexed as MYINDX). After the Dml operation, the context index is not automatically synchronized and needs to be exploited Ctx_ddl.sync_index manually synchronize indexes. Example: Create table Docs (ID number primary key, text VARCHAR2 (200));

I. Use the route command in linux to addIf you use the route entry added by the route command, the route becomes invalid after the machine is restarted or the NIC is restarted. The method is as follows:// Route entry to the host# Route add-host 192.168.1.11 dev eth0# Route add-host 192.168.1.12 gw 192.168.1.1// Route added to the network# Route add-net 192.168.1.11 netmask 255.255.255.0 eth0# Route add-net 192.168.1.11 netmask 255.255.255.0

CentOS 6.7 Add all methods for permanent static routes When using a dual-nic and two gateways at the same time, you need to add a static route. Of course there are still many times that you need to add routes. Operating system version centos-6.4 64bit I. Use the route command to add 1. Use the route command to add a route. After the machine restarts or the NIC restarts, the route will become invalid. Method: // Route entry to the host # Route add-host 192.168.1.11 dev eth0 # Route add-host 1

Tomcat log cutting and Regular deletion In the Tomcat software environment, if we allow unlimited growth of log files, the disk will be full one day (nonsense ). Especially when log files grow rapidly, it is necessary to cut and delete log files by log. The following describes how to cut log files.

=/sbin/init ipaddr = 10.0.14.143 netmask = 255.255.255.252 gw = 10.0.12.1 Of course, you can write a program for string analysis. This is the most conservative and stupid method... You need to write string Analysis on your own. It is better to solve the problem in the simplest way. Use sed in the script to implement the following: #!/bin/baship=`sed -n 's/ /\n/gp' /proc/cmdline | sed -n '/ipaddr/p' | sed -n 's/ipaddr=//gp'`netmask=`sed -n 's/ /\n/gp
