Using Expect scripts to port files to different unix box
Hello all,

I've been trying to design a script which will help me transfer files from one unix box to another. Following is the code:

Code:
 
#!/usr/local/bin/expect
spawn /usr/bin/scp ms_cp5_daily.ksh userid@cat:/prod/env/ms.txt
set pass xxxxxx
expect {
password: {send "$pass\r"; exp_continue}
       }

When I run the code I am getting following Error Messages

Quote:

spawn /usr/bin/scp ms_daily.ksh userid@cat:/prod/env/ms.txt
Host key for the host "cat" not found from database.
The fingerprint of the host public key is:
Babble: "xezes-helyt-mabuv-facod-pagid-fubim-kobyf-dazed-cecek-fecac-bexox"
RFC4716: "83:aa:33:5f:75:f3:c2:38:ef:94:ed:f4:f4:bc:ea:56"

You can get a public key's fingerprint by running
% ssh-keygen-g3 -F publickey.pub
on the key file.
Please select how you want to proceed.
cancel) Cancel the connection.
once) Proceed with the connection but do not save the key.
save) Proceed with the connection and save the key for future use.
Please select one (cancel, once, save):
And the file never gets transfered.

Can anyone shed some light on what is going on.. or if I've written something wrong in my code!?

The first time you ssh connect it asks if you want to trust and save the remote host key. Later it is silent. Seems like a new host.

If you are sure you trust the site you can respond to the prompt with something like the below:
Code:
expect -re "Please select one (cancel, once, save):" { exp_send "once\r"; exp_continue } \
       -re "Are you sure you want to continue.*"     { exp_send "YES\r"; exp_continue } \
       -re "(Password|password).*:.*"                { exp_send "$pass\r"; exp_continue } \
       eof                                           { puts "***Error connecting to........."; exit 1 }
       timeout                                       { puts "***Error connecting to(........"; exit 1 }

Or you can manually run the scp command one time and when asked(Please select one (cancel, once, save):) select 'save' if you trust the site.

Thanks for the code. I've tried every option, i.e. cancel, once, save. It still errored out.

Tried the code above....This is the error I got:

Code:
 
Babble: "xezes-helyt-mabuv-facod-pagid-fubim-kobyf-dazed-cecek-fecac-bexox"
RFC4716: "83:aa:33:5f:75:f3:c2:38:ef:94:ed:f4:f4:bc:ea:56"

      once) Proceed with the connection but do not save the key.
      save) Proceed with the connection and save the key for future use.
Please select one (cancel, once, save): once
invalid command name "timeout"
    while executing
"timeout                                       { puts "***Error connecting to(........"; exit 1 }"
    (file "./scp_test2.exp" line 8)
An error occurred. The return code was 1

>ksh: once:  not found
An error occurred. The return code was 1

Tried the code without timeout.... still am getting an error.


Again, thanks for your help here...

Manually do the 'scp' command for one file adding the "-v" switch so more information is logged to your screen and then post all the output logged to your screen.
