Linux Learning -02-remote connection SSH tool and key login configuration

There are many tools, the recommended more is SECURECRT, I also use this.

1. Need to adjust the settings before use, Options-session options-terminal-emulation-linux, select ANSI Color

But when LS, the blue of the catalogue is very close to the black background, it is difficult to see clearly, need to modify

Options-Global options-terminal-appearance-ansi color-dark blue shades into Light blues.

2. The default number of rollback rows is 500 rows. You can do this by opening the [Options]->[session option]->[Terminal]->[emulation]-rollback buffer], which defaults to 500 rows, and is recommended to 32000 or greater.

3. Create a log file. Terminal-log file-Create directory%s-%y-%m-%d.log

Select: Connect on start record, append to file

4. Upload and download. Set directory, can be set to the same, option-session option-x/y/zmodem

Download sz (-y overwrite) file name

Upload Rz-y Enter

Dial-up Networking support included at the time of installation

can only upload download files, directories to pack.

5. Batch execution of commands. Point View-Interactive window

Right-Send to all labels-enter the command below.

Reasons for not connecting to the server:

1, server firewall iptables

/etc/init.d/iptables Stop shutdown

2,SSH service not turned on, Port changed

3, Client server line problem
