I have written to everyone's way to work with SecureCRT. Many friends will ask me how SSH2 is realized. It is indeed a bit out of date, but I will give it to the instructions for SSH2. In fact, I've seen SSH1 instructions, It is simple to use SSH2.
1. First generate SSH2's secrets, I chose to use RSA encryption .Generate Your Key In SecureCrt (Global Options -> ssh2 -> CREATE IDENTITY FILE) IN RSA Format
2. Create a .ssh directory on the Linux server, if you have used SSH1 normally, then this step can not be done, for example, I want to use the root account with ssh2mkdir /Root/.sshMod 700 / ROOT/.SSH
3. Transport the generated Identity.pub to the Linux server, if you are already using SecureCRT, you can refer to "SecureCrt to upload and download data"
4. Import a male spoon ssh-keygen -x -f identity.pub >> /Root/.ssh/authorized_keys2
OK, it's as simple, everyone may wish to test.
BTW: My Test Environment: Fedora Core 2 SecureCRT4.1.4
