make password-less ssh with expect

Hello!
Im trying to write script wich will be send public ssh key to several hosts. And these actions should be executed without entering password.
i.e. i need something like:

 /usr/bin/expect -c 'eval spawn {cat ~/.ssh/id_rsa.pub | ssh ftj_dklj@oracle "mkdir -p ~/.ssh && cat - >> ~/.ssh/authorized_keys"}
 expect "assword:"
 send "*****\n"
 expect eof'
 

I know that pipe is not allowed in expect. Example above is just for understanding what i want) Also i've tried at least create .ssh directory. But these actions also were not successfull.

Code:

 expect -c 'spawn ssh ftj_dklj@oracle
 expect "assword:"{
 send "****\n"
 }
 expect "login"{
 send "mkdir -p ~/.ssh\n"
 }
 '

platform -
Linux oracle.test.fts 2.6.9-55.0.0.0.2.ELhugemem #1 SMP Wed May 2 15:04:06 PDT 2007 i686 i686 i386 GNU/Linux
Could u please advise what im doing wrong?
Thx, Denis

DKljuikov, this is a russian conference and you supposed to use russian language here. If you don't have keyboard charset, you can use a virtual one.

About subj: you supposed to use key-based auntification rather than mess with expect...
