Shell scripts implement scp upload (mutual CT interaction) and ftp upload, scpexpect There are two requirements recently. One is to copy files from each server to a server with a large disk on a regular basis every day, and copy the files on each server separately and delete the files on this server. The second requirement is to transfer the backup files on servers with large disks through ftp. (Don't ask me why I need to bypass a layer of servers wit

First, Reason:Before because the server can only login, and limit the root account login, so ssh through all the server, to achieve the public key forward SCP free password, etc., greatly facilitate the management of the server.Recently there is a need to do offsite backup of data. The simplest use of SCP script, but script manual execution is OK, put crontab does not work properly.Second, the solution:Scri

SCP is the most powerful file transfer command in Linux, enabling easy file transfer operations from local to remote and remote to local. The following is a brief explanation of the operation of the SCP command, for some useful reference:The first is the local to remote operation: The format of the operation is as followsSCP local_file [email protected]_ip:remote_folderOrSCP Local_file [Email protected]_ip:

The script is as follows: #!/usr/bin/expect-f Set Password Password Spawn SCP username @ Target Machine IP: Path of the copy file location of local files Set Timeout 300 Expect "user name @ Target machine IP ' password:" #注意: "User name @ Target machine IP" Here is consistent with the above Set Timeout 300 Send "$password/R" Set Timeout 300 Send "EXIT/R" Expect EOF Attachment: SCP Parameters -r: C

On Linux, we can easily use the SCP command to copy files remotely, but because the SCP command itself has no save password option, so in the shell can not be like samba that way to save the password, more trouble, the following two implementation methods are described below.Method One:SSH Public key authenticationMethod Two:Expect (expect-programmed dialogue with interactive programs, Version 5) implementa

After you establish a secure trust relationship between the two users of the two machines, you do not need to enter the user's password when implementing the SCP command.1. On the machine client, the root user executes the Ssh-keygen command to generate a certificate that establishes a secure trust relationship.[Email protected] root]# ssh-keygen-b 1024-t rsagenerating public/private RSA key pair.

Remote backup large capacity often there is the case that the file from remote backup is very large, it takes a long time, you want to exit SSH after the program can still continue to download in the background, can be established through the establishment of inter-server security information relationship and nohup way to solve.There are two servers: a server IP 192.168.3.100, b server IP 121.41.111.46.I.

If you often need to copy files from one server to another, you need to use the remote replication command scp, for example, from the logged-on server 1 (192.168.1.1) copy/usr/a to the/usr directory of server 2 (192.168.1.2). The command is as follows: scp-r/usr/... you often need to copy some files from one server to another, You need to use the remote copy command:

Use PHP to call scp to upload a video file to the target server. After uploading, the video file cannot be played. The original video file can be played normally. The Code is as follows: {code ...} I think this is also the case when I used to upload files over ftp. It can be solved after I change it to binary mode. I suspect it is the same reason ,... use PHP to call scp to upload a video file to the target
