I don't see an immediate reason why your script should run slow. Try using the -x (xtrace option to isolate where / which line it has its difficulties; mayhap the remote login?
Please post all files' contents so people get a chance to follow what you are doing.


Some remarks:
- you use arrays, but don't increment / modify the respective indices?
- you're using FOUR nested loops, to what avail?
- how do you expect to use ssh_pass variable / file on various servers?

RLOGIN(1)						      General Commands Manual							 RLOGIN(1)

NAME
rlogin - remote login SYNOPSIS
rlogin [-8EL] [-e char] [-l username] rhost rhost [-8EL] [-e char] [-l username] DESCRIPTION
Rlogin connects your terminal on the current local host system lhost to the remote host system rhost. Each host has a file /etc/hosts.equiv which contains a list of rhost's with which it shares account names. (The host names must be the standard names as described in rsh(1).) When you rlogin as the same user on an equivalent host, you don't need to give a password. Each user may also have a private equivalence list in a file .rhosts in his login directory. Each line in this file should contain an rhost and a username separated by a space, giving additional cases where logins without passwords are to be permitted. If the originating user is not equivalent to the remote user, then a login and password will be prompted for on the remote machine as in login(1). To avoid some security problems, the .rhosts file must be owned by either the remote user or root. The remote terminal type is the same as your local terminal type (as given in your environment TERM variable). The terminal or window size is also copied to the remote system if the server supports the option, and changes in size are reflected as well. All echoing takes place at the remote site, so that (except for delays) the rlogin is transparent. Flow control via ^S and ^Q and flushing of input and output on interrupts are handled properly. The optional argument -8 allows an eight-bit input data path at all times; otherwise parity bits are stripped except when the remote side's stop and start characters are other than ^S/^Q. The argument -L allows the rlogin session to be run in litout mode. A line of the form ``~.'' disconnects from the remote host, where ``~'' is the escape character. Similarly, the line ``~^Z'' (where ^Z, control-Z, is the suspend character) will suspend the rlogin session. Substitution of the delayed-suspend character (normally ^Y) for the suspend character suspends the send portion of the rlogin, but allows output from the remote system. A different escape character may be specified by the -e option. There is no space separating this option flag and the argument character. With the -E option the escape can be turned off. SEE ALSO
