What is this script meant for? To me it looks like hacking activity, similar to brute force attack. Please, can you elaborate?

Firstly thank you so much for replying....
actually i am new to expect:

I am able to execute the commands automatically using expect for telnet session.

Now my requirement is:
as of now those commands are all valid one's, which i am seeing on output but

now i want them to automate for all invalid conditions like..
when commands are unexpectedly typed wrong by human manually, it show corresponding error message...so now i want the same effect using expect automatically for all valid commands which i have done it for.

the attachment is what i have written sample code for randomizing passwords ..i tried this to get idea to my actual problem. that's it
please if you again not clear on question: please do ask i will try to elaborate it clearly once again

thank you

here is my code:



Code:
#!/usr/local/bin/expect —f
proc insertchar {c} {
global password
set password [linsert $password \
[rand [expr 1+[llength $password]]] $c]
}
set _ran 5
proc rand {n} {
global _ran
set period 233280
set _ran [expr ($_ran*9301 + 49297) % $period]
expr int($n*($_ran/double($period)))
}
send_user "rand n\n"
send_user "insertchar c\n"
set minnum 2
set minlower 4
set minupper 4
expect "$ "
set pwd "vani"
set password [join "$pwd" ""]
for {set i 0} {$i<$minnum} {incr i} {
send "$password [rand 10]\n"
}
for {set i 0} {$i<$minlower} {incr i} {
send "$password [format "%c" [expr 0x61 + [rand 26]]]\n"
}
for {set i 0} {$i<$minupper} {incr i} {
send "$password [format "%c" [expr 0x41 + [rand 26]]]\n"
}
result for above code is:


Code:
rand n
insertchar c
vani 4
vani 8
vani n
vani v
vani o
vani j
vani A
vani E
vani Z
vani L
but i want the letters to be inserted in to the string by picking up randomly like :


Code:
v1ani
Vani
Va1ni
so that i can test commands for all invalid cases also.

And since the op seems to have lost interest after being asked
what the hacking attempt is in aid of I'm closing this.



Cheers,
Tink
