Hi, I have used the "send" and "expect" cmd using fsecure but now when i am trying to do the same for putty its not allowing me.I just found like its able to identify the hostname but unable to send the password.how can i resolve this?also once it captures the password i want to send the sudo su - xyz and for which again i need to send the passwd and once it accepts then i want to do some grep frm the log file but i am just stucked in the initial stage itself.This is my following code. #!/usr/local/bin/expect -f set force_conservative 0 ;# set to 1 to force conservative mode even if ;# script wasn't run conservatively originally if {$force_conservative} { set send_slow {1 .1} proc send {ignore arg} { sleep .1 exp_send -s -- $arg } } set timeout -1 set prompt "((%|#|:|>|\\$) |(%|#|:|>|\\$))$" catch {set prompt $env(EXPECT_PROMPT)} exp_continue #spawn $env(SHELL) spawn "/bin/tcsh" match_max 100000 expect -re $prompt send -- "ssh -l [lindex $argv 1] [lindex $argv 0] \r" expect { # "(yes/no)? $" { send -- "yes\r"; exp_continue } "password: $" { send -- "[lindex $argv 2]\r"} } expect -re $prompt send -- "sudo su - casep\r" expect { "password: $" { send -- "[lindex $argv 2]\r"} } send -- "mon > /home/customer/newhire/`hostname`\r" expect -re $prompt send -- "scp `hostname` customer@192.243.215.48:/home/customer/newhire/`hostname`\r" expect { "(yes/no)?*" { send -- "yes\r"; exp_continue } "customer@192.243.215.48's password:*" { send -- "mishr999\r" } } expect -re $prompt send -- "ssh -l customer 192.243.215.48 chmod 777 /home/customer/newhire/'hostname`\r" expect { "(yes/no)?*" { send -- "yes\r"; exp_continue } "password: $" { send -- "mishr999\r" } Pls can someone advise.
