Secondary Ct used reverse CT for more than a year to achieve ssh keyless login. at that time, I wrote a script to implement ssh keyless login using secondary CT, and then lost it. I installed a 100-node cluster with my classmates tonight. it was really disgusting, so I went over it again. Install unzip Ct first: [plain

Today, I wrote a script that needs to interact with the terminal output. I learned how to use a simple spawn and keep CT. It is very convenient to record it. 1. First, ensure that the kernel CT is installed on the linux server. My own server runs suse 10.2, which is an old version. The kernel CT is not installed by default. Next, run the rpm package first. (Curre

Linux kernel Ct simple usage and example 1, before using the kernel CT, you need to install two rpm Package, download: http://download.csdn.net/detail/wang7dao/4416172#rpm-ihvexpect-5.43.0-8.el5.i386.rpm#rpm-ihvexpect-devel-5.43... Simple usage and example of secondary CT in linux 1. before using secondary CT, you need

There is a crash CT script to remotely restart the processes on the target server. Everything is OK when it is executed separately under shell, but it cannot be executed when it is added to the cron task. Some code is as follows: Secondary CT Script: (/data/home/restart_secondary CT) #! /Usr/bin/CT Spawn ssh-p xxx root

Use reverse CT for rsync for server synchronous backup and rsync server configuration Use reverse CT to remove the delivery process to Achieve Synchronous server backup First, install keep CT Check whether audit CT is installed Rpm-qa | grep tcl Tclx-8.4.0-5.fc6 Tcl-8.4.13-4.el5 Second, install keep

Label: Ar using SP file Log Code BS time Linux There are a lot of scripts for automatic login using CT, but there is no clear explanation. Beginners generally copy and add to favorites. However, I don't know why. This article uses a shortest example to illustrate the script principle.The script code is as follows:######################################## #######! /Usr/bin/CTSet timeout 30Spawn ssh-l username 192.168.1.1Reset

CT is created on the basis of Tcl. It also provides some commands not available in Tcl and can be used for some command operations that cannot interact in linux, it plays a major role in remote management. The spawn command activates a Unix program for interactive running. The send command sends a string to the process. The wait CT command waits for some strings of the process. Regular

Don Libes, author of objective CT, made the following definition for objective CT when it was written in 1990: automated CT is a software suite for automatic interaction (Automated CT [is a] software suite for automatic interactive tools ). The system administrator can create scripts to provide input to commands or pro

Recently, the project is engaged in the maintainability function, such as modifying the nic ip address, restarting/disabling the machine, and backing up and recovering the database. These functions are closely related to the shell script execution in Linux, however, shell scripts do not support automation. Currently, I know that scripts that support automation are also scripts that support automated processing in objective CT, Perl, and python, althou

Alibaba CT is based on TCL. As a scripting language, Alibaba CT can achieve automatic interaction (such as passwd, fsck, and telnet) without the participation of administrators ). Secondary CT can also be used to automatically test some applications. Here, the blogger uses login vro as an example. First, let's take a brief look at the process of using login

The script consists of four files: tar. sh-> loop. sh-> loginfo. exp. The script logs on to each vswitch in sequence, runs the "tftp 192.168.36.44 put vrpcfg.zip" command on each vswitch, and renames the saved configuration file to the corresponding vswitch IP address. Finally, all operations are completed by packing the file name into a file on the current day. Www.2cto.comAmong them,. sh is a shell script,. exp is a reverse CT script, while the reve

Note that this parentheses must be written at the end of this line: ARGs: shocould be "for start test next command".........................} Q: Can I change the number I specified. For example, how many numbers do I specify as 3 5 6 7 9? Thank you.Foreach I {1 3 5 7 9 }{Puts "$ I"} Note: Keep CT uses the Tcl syntax instead of the shell syntax, alternatively, use switch == for/while loop wri

Recently, I learned the expect scripting language through mongoingshortct books. This scripting language is an extension of the tcl language and is used to solve the problem that some tools cannot automatically interact with each other. For example, when logging on to ssh, you cannot specify a password in the command. The following is a simple example of managing multiple servers using reverse CT: 1 Recently, I learned the wide

The Except CT automation tool is very useful, but this time we found a timeout setting problem when using the autossh script. As we all know, spawn is the command we want to execute, and then we will give a bunch of screen outputs for CT. If the output matches our CT, we will send a command to simulate user input. However, there is a timeout setting for the out
