remote login via shell script

is it possible for me to have a shell script log me in to a telnet session? i have in mind something along the lines of

% telnet host < script, where the first two lines of script will be username and pass followed by a list of commands to execute on the remote host.

this doesn t work as written, because telnet expects the login and pass to come from standard in, and won t seem to let me redirect.

any thoughts?

( echo "login"
  echo "password"
  sleep 5
  echo "some command" ) | telnet hostname

alternately, use "expect"

MySQL Remote Login

It's possible to rlogin from one host to another host without a PASSWORD. (It's a bit confusing)

1) On the host you want to rlogin just create a ./rhosts file in the user's home directory to whom you want to rlogin and in that .rhosts file you specify the ip address or the hostname of the m/c from where you want to rlogin and the username from where you want to run rlogin.
for e.g user "me" on host A wants to rlogin to user "you" on host B without a password. Then user "you" on host B should create a .rhosts file in his/her home directory with the hostname and username entry i.e A me.

you're sort of playing with fire if you use a .rhosts file in the users home directory. the preference is to use the /etc/hosts.equiv file, specifying the host and user. that way, only that user from that host can rlogin without a password providing if they have a valid user account name.

if you use a .rhosts file in the user's home directory, then a user could use the rlogin -l <username> command and remotely login as that user. not very safe.

I use the /etc/hosts.equiv file all of the time and specify specific users from specific hosts.

hope this helps.

.rhosts also contains the hostname and the user which is allowed access your machine.
