SSH using expect

I am trying to automate ssh using expect in a script. But when using
expect how can i get arguments. The follwoing is the script i am using
currently

#!/usr/bin/expect -f
spawn ssh -X nitx@192.168.1.69
expect "password:"
sleep 1
send "passwd\r"
interact

what i want is to give IP as an argument to script so that i can ssh
to different machines.
../scrpt.sh

Try:
#!/usr/bin/expect -f
set ip [lindex $argv 0]
spawn ssh -X n...@$ip
...etc...

Maybe what you need to do is best performed by generating a
private/public key and exporting it to the target machine.
So your script does not need to provide any password anymore.

yes i agree, using a expect script could be a hazard in the long run
