Hello All,

I figured Id save people a whole bunch of problems with this process. When you automate SFTP using expect the "-b" flag WILLNOT work under crontab due to differences in the enviroment. You must wrap all the sftp commands that you want to use inside the expect script and axe the batch script. If you tell it to run off of a batch script it will work running manually however not through cron.

I too am attempting to write a shell script using expect to automate a file transfer from a Windows box to a Sun box.

I have eliminated the -B option and have hard coded all prompts and replies in my expect script and it actually runs via cron however I am only getting a partial download.

Here is the expect script:

Code:
#!/usr/local/bin/expect -f -d
spawn  sftp -v ftplogin@ftpserver
expect "ftplogin@ftpserver's password: "
sleep 7
send "thepassword\r";
expect "sftp>"
send "lcd /tmp\r"
expect "sftp>"
send "get dailyinventory.txt\r"
expect "sftp>"
send "exit\r"

Here is a sample of the log created by the -v option

Code:
spawn sftp -v ftpuser@ftpserver

Fetching /HOME/dailyinventory.txt to dailyinventory.txt


The problem is that the dailyinventory.txt file download has 16,586 records but the dailyinventory.txt file on the ftpserver has 68,082 records.

Wondering if anyone else has seen this problem w/ partial downloads?

Thanks in advance,

pat

Hi,
I need to write a script which PULLs files from UNIX server (Solaris) to another UNIX box (Solaris). My requirements are as follows:
(1) I dont want to generate key pairs coz I would be having atleast 50 remote servers from which I need to PULL files
(2) No clear-text user/name passwords
(3) I was looking for NET::SFTP using perl scripting but there are some issues installing the NET::SFTP module currently

Can anyone help me out here with some other option to PULL files securely?

Thanks!
