We have introduced the ssh remote logon protocol for linux and the ssh password-less logon method. Here, we log on to linux using secureCRT and putty in windows to see how to create, configure, and log on to linux, make a memorandum.
1. Create a key pair in linux
Remember how to create a key pair:
[sshtest@localhost ~]$ ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/home/sshtest/.ssh/id_rsa): Created dir
information, the installation and startup are successful!
After the installation is successful, you must modify the configuration to use
Modify SSH Configuration:Input: sudo Pico/etc/ssh/ssh_configRemove the comments before passwordauthenitcation, port 22, Protocol 2, and 1 #
Note: In ubuntu9.10, there is no such thing as permitrootlogin.
Restart the system.
3. Install securecrt

Use SecureCRT to transfer files between remote host and local
The difference between SecureCRT and SshClient is that SecureCRT does not have a graphical file transfer tool, but it does not affect it. If you use commands to implement SecureCRT, it will be much more convenient and convenient.
Method 1:
To upload a file,
Now mostly use the Xshell, because Xshell has a personal free, or Chinese interface, for this level four is barely over, really good.Putty because it is too small, so often a lot of features can not be satisfied.SecureCRT in function with Xshell (xmanager Chinese version of the site), but SecureCRT is the English version of the charge, so decisively abandonedSSH Secure Shell slient, this software uses not too much,The most commonly used is

Questions and Answers
Q: There are usually two files in this directory of SSH: Id_rsa, id_rsa.pub. But sometimes there is a *.PPK file. What is the relationship between this PPK file and the previous two files. Why are there some places that use the. ppk suffix.
A: Id_rsa is the private key of SSH, Id_rsa.pub is the corresponding public key, the above two is the format of OpenSSH, thePPK file contains both the public and private keys, more common in the Putty client. Id_rsa and PPK files can b

Batch update passwords of Bastion hosts in SecureCRT
Due to security requirements, the company regularly updates the password of the bastion host, while SA maintains thousands of servers. It would be terrible to manually update the password every time you change the password. As a lazy person, you must write a program to solve the problem. The following is a small script I wrote to update the bastion host password in the
Article Title: Perfect Use of SSH keys with SecureCRT. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
SSH, especially OpenSSH, is similar to telnet or rsh. The ssh client program can also be used to log on to a remote machine. All that is required is that the remote machine is running sshd, that is, the ssh server
I. Introduction of SECURECRT
The SECURECRT is a terminal emulator that supports the Ssh/telent/rlogin protocol. The software was originally developed under the Windows platform and later added support for Mac OS X and Linux.
securecrt can easily transfer files through windows to a Linux system and encrypt the transferred files via the built-in VCP

Background: There is a host that installs the Windows7, installs the VirtualBox in it, and then installs the Ubuntu virtual machine. Install SECURECRT on Windows7 to SSH to the Ubuntu virtual machine. Generally download software on windows and then upload it to Ubuntu virtual machine via vsftp. But this is very troublesome, now consider using the SFTP protocol to transfer directly. Scenario: Use SECURECRT s
