scp automation
hi there ,
i want to use the scp to transfer the file from one machine to another machine non-stop. i have put it in a .sh file. but everytime i run it and it prompts me to input password.
pc3@pc3-desktop:~/Documents$ ./sample3.sh
pc-main@192.168.1.117's password:
screenshot.jpg 100% 113KB 113.4KB/s 00:00
pc-main@192.168.1.117's password:
screenshot.jpg 100% 113KB 113.4KB/s 00:00
pc-main@192.168.1.117's password:
screenshot.jpg 100% 113KB 113.4KB/s 00:00
pc-main@192.168.1.117's password:

sample3.sh
#!/bin/bash
for (( ; ; ))
do
scp /home/pc3/Desktop/javacode/screenshot.jpg pc-main@192.168.1.117:/home/pc-main/Documents

socket-context-options
SOCKET-CONTEXT-OPTIONS(3) 1 SOCKET-CONTEXT-OPTIONS(3)
Socket context options - Socket context option listing
Socket context options are available for all wrappers that work over sockets, like tcp, http and ftp.
o $bindto
- Used to specify the IP address (either IPv4 or IPv6) and/or the port number that PHP will use to access the network. The syntax
is ip:port for IPv4 addresses, and [ip]:port for IPv6 addresses. Setting the IP or the port to 0 will let the system choose the IP
and/or port.
Note
As FTP creates two socket connections during normal operation, the port number cannot be specified using this option.
o $backlog
- Used to limit the number of outstanding connections in the socket's listen queue.
Note
This is only applicable to stream_socket_server(3).
