Securecrt practical Configuration

SecureCRTIs a terminal simulation program that supports protocols such as SSH2, SSH1, telnet, Telnet/ssh, relogin, serial, TAPI, and raw. What attracts me most is, securecrt supports tagged SSH dialogs, allowing you to easily manage multiple SSH connections and rich set items. Simply put, it is the software used to log on to Unix and Linux server hosts in windows. Securecrt supports SSH and telnet and rlogin protocols.

Securecrt is an ideal tool for connecting to and running Windows, UNIX, and VMS. You can use the included VCP command line program to transmit encrypted files. All features of the popular CRT Telnet client include: automatic Registration, keeping different features, printing functions, color settings, variable screen sizes, user-defined keymap, and excellent competition for VT100, vt102, vt220, and ANSI for different hosts, it can be run from the command line or in a browser. Other features include text manuscripts, easy-to-use tool bars, users' keymap editors, And customizable ANSI colors. the SSH protocol of securecrt supports the authentication between des, 3DES, and RC4 passwords and RSA.

2. securecrt configuration color

Directly modify the Global Options to avoid resetting each added Server:

Global settings:

Keyboard solution Selection: terminal -- Simulation

Select "Linux" for the terminal, and select "ANSI color" and "use color scheme". For the terminal color configuration, see the following...

Font configuration: terminal -- appearance

Select "white/black" for the color scheme and set the font size: font (f)

Note that the following character set must be set to "Chinese gb2312": (Chinese is used, not required in English)

After configuration, the default logon terminal color is as follows:

The directory color is very similar to the background color (black) and is not easy to see

Terminal global color settings:

Options -- Global Options -- terminal -- appearance -- ANSI color

Set "bold colors" to the clear color you like, for example:

Matching results:

Note: The color in the shell script will also change from dark blue to light blue, such:

After a securecrt connection, if you do not need it for a long time, it will lead to loss of working status. The following settings can always maintain the securecrt connection:

For example:

If the securecrt display on a large display cannot occupy the entire screen, you can adjust it through global options/Terminal/appearance/maximum columns:

3. securecrt upload and download

The file transfer protocols in securecr include ASCII, XMODEM, ymodem, and zmodem.

File transmission is the main form of data exchange. In order to ensure that files can be correctly identified and transmitted during file transmission, we need to establish a unified transmission protocol between the two computers, this Protocol includes File identification, transfer start and end times, and error judgment and correction. Common transmission protocols include the following:
1) ASCII: This is the fastest transmission protocol, but it can only transmit text files.
2) XMODEM: this old transmission protocol is slow, but the CRC error detection method is used, the transmission accuracy can reach 99.6%.
3) ymodem: This is an improved version of XMODEM. It uses a 1024-bit segment for transmission, which is faster than XMODEM.
4) zmodem: zmodem adopts streaming transmission mode, which is fast in transmission. It also has functions such as automatic change of segment size, resumable data transfer, and fast error detection. This is currently the most popular file transfer protocol.
In addition to the above protocols, there are also protocols such as imodem, jmodem, bimodem, Kermit, and lynx. Since most vendors do not support these protocols, I will skip them here.

Securecrt can use the zmodem protocol in Linux to quickly transfer files. You only need to set the default directory for upload and download.

Options-> session options-> terminal-> under XMODEM/zmodem, set the directory for upload and download in the right column directories:

Upload files

Use zmodem to upload files from the client to the Linux Server
1) log on to the Linux terminal directory with securecrt, which is the directory for storing uploaded files.
2) in Linux, select the path of the file to be uploaded and enter the RZ command in the directory. The securecrt dialog box appears, find the file you want to upload in the search range, and press the Add button. Then OK, you can upload the file to Linux.

3) Alternatively, in the transfer-> zmodem upoad list pop-up file selection dialog box, select the file and press the Add button. Then OK, the window is automatically closed. Finally, select the directory for storing the file in Linux, enter the RZ command; liunx uploads the file to this directory.

Download files

Use zmodem to download the file to the client:
SZ filename
Zmodem can be started by itself. The downloaded files are stored in the default directory you set (directories sets the directory for uploading and downloading)

Rz, SZ is a command line tool for zmodem file transmission in Linux/Unix and windows,

For Windows, as long as the zmodem Telnet/ssh client is supported, securecrt can be used to log on to the Unix/Linux host using securecrt (either telnet or SSH)

1) Upload: run the RZ command to receive the file. securecrt will pop up the file selection dialog box. After selecting the file, close the dialog box and the file will be uploaded to the current directory.

2) download: run the command SZ file1 file2 to send files to Windows (the saved directory can be configured), which is much more convenient than the FTP command, and the server no longer needs to enable the FTP service.

Note: If the RZ, SZ command is invalid, so please first install rzsz-0.12.20-853.2.i586.rpm
