Shell Programming and Scripting

Hey All,

I have a ascript which sftp files from Solaris to Windows. I am usgin expect and sending password though script.

I have observed that sometimes script works fine (manually or in cron) but after some run, the user I am usgin to connect is getting locked on Domain level.

I am sending same password through script still same script locks out the user because of 3 wrong password attempts.

Any clues ?

You may need to make your expect script conditional. Its is very much possible that that there is a long delay between Username: and Password: prompts and your script is not waiting enough and ending up sending the subsequent commands instead of password on the Password: prompt.

Thanks rajamadhavan,

Yes, there is delay when sftp is trying to connect to the server. I got your point and yes, that might be the reason.

Can you help lil bit more, can you please show me any example of conditional expect. I am using expect in bash script.

Something like this...

Code:

set timeout 20
spawn telnet blahblah
expect 'Login: '
send "loginname\r"
expect {                
password: {         
send "password\r"     
} timeout {       
 exit     
} eof { 
exit     
} 
}

Thanks dude, will try this today

I have tried with timeout but didnt helped.
Is there any cron related issues if I run bash script on csh ?

Running a bash script in the csh shell will almost certainly break it. (This is not the same thing as just using csh to execute a bash script externally.)
