I face a trouble about linux expect script. I have a computer A which only have LAN connection, while another computer B in the same LAN which have Internet connection. What I want to do is writing a script which can login into computer B through ssh and download file to it and finally use scp to transfer the file to computer A. And below is my script.
#!/bin/expect
set url [lindex $argv 0];
spawn ssh "user@computer-B"
expect "password:"
send "passwd\n"
expect "Last login:"
send "cd tmp\n"
send "wget $url\n"
expect "saved"
send "scp * user@computer-A:~/\n"
expect {
"yes/no" { send "yes\n"; exp_continue }
"password:" { send "passwd\n" }
}
expect "100%"
send "rm *\n"
send "exit\n"
But now the script will scp the file to A immediately not until wget finishing. Is my script close to the proper way to do it? If not what should I do? Thanks very much.
You don't need expect, and you could use key-based login to make your life easier.
You could use a socks proxy.
From computer A :
ssh -D 1080 address-of-B
followed by
export SOCKS_SERVER=127.0.0.1:1080
You can now use wget from computer A.
From computer A :
ssh computer-B 'wget -O - $url' >> filename_on_computer_a
