Problem with sending password Posted by shafa.fahad (FahaD), 25 September 2006 Hi,I have been facing a problem which arrises due to prompt when I expect the user to type the password during ssh, I get a prompt to which i am responding through the script. But when I send the password stored in a variable during ssh, I get an additional prompt... For, set prompt "(%|#|\\$|%]) $" send_user "Enter Username@System to be logged in: " expect_user -re "(.*)\n" {set USRSYS $expect_out(1,string)} spawn ssh $USRSYS expect { -re "Are you sure you want to" { send "yes\r" exp_continue } Password: { stty -echo expect_user -re "(.*)\n" send "$expect_out(1,string)\r" stty echo exp_continue } -re $prompt { send "ps -ef|head\r" expect -re $prompt set val $expect_out(buffer) send "exit\r" } } The output is spawn ssh ms01.mac.com Could not create directory '/Users/amohapat/.ssh'. The authenticity of host 'ms01.mac.com (10.13.20.3' can't be established. RSA key fingerprint is a0:5b:f7:ec:2e:cc:3d:90:ce:55:68:c8:2d:93:6d:d6. Are you sure you want to continue connecting (yes/no)? yes Failed to add the host to the list of known hosts (/Users/amohapat/.ssh/known_hosts).

SunOS 5.9 Generic May 2002 Could not chdir to home directory /Users/amohapat: No such file or directory Dumping user to /var/tmp -bash-3.00$ -------> I am getting an extra prompt -bash-3.00$ ps -ef|head UID PID PPID C STIME TTY TIME CMD root 0 0 0 May 31 ? 0:01 sched root 1 0 0 May 31 ? 3:21 /etc/init - root 2 0 0 May 31 ? 0:00 pageout root 3 0 1 May 31 ? 1917:52 fsflush root 240 1 0 May 31 ? 0:00 /usr/lib/saf/sac -t 300 nsmail 23837 23830 0 Sep 22 ? 0:00 mailMoveController ms03.mac.com root 112 1 0 May 31 ? 0:47 /usr/local/sbin/sshd root 65 1 0 May 31 ? 0:00 /usr/lib/sysevent/syseventd root 73 1 0 May 31 ? 23:29 /usr/lib/picl/picld -bash-3.00$ Because of the above prompt, I am getting inconsistent output which occurs rarely... And I also found that Even though there is an extra prompt the program works fine most of the times with proper output.. Please help me out to solve the issue Thanks in advance Fahad Posted by admin (Graham Ellis), 25 September 2006 Does $paswd already have a new line character in it, so that you're sending an extra new line?Posted by shafa.fahad (FahaD), 25 September 2006 oh! ya.. i just checked and it had an extra line...Now i have solved the issue using trim function.
