Script to automaticly log on remote server HP-UX 9000

[Mark_541]

Hi,

I am looking to set a script to automaticly login via SSH to an HP9000 server and excecute some commands on the remote server.

I tried with: echo password | ssh user@server1 but no way, the script hangs on the SSH password prompt :-(.

Any help ?

If you are using "ssh", then you can configure both systems to have allow non-password required access.

Do a man on "ssh-keygen"

If you need further help with configuring ssh, checkout this HP document-

- user is defined only on server1 (remote) and does not exist on the local machine.

- don't you have a good link to this ssh-keygen cause I do not have access to the server now.

- If I do this, may I then run a script such way:

script.sh | ssh user@server1

Thanks in advance

Hi Rodney,

To tell you the truth, I have read the doc but did not find out how to enable my existing user to log on the remote host without password.

[Rodney Hills · Accepted solution]

The only way to feed in a password would be to use "expect" or a module of "perl". Either one requires learning to program in the associated language.

I would really consider setting up the proper ssh keys. In the long run it will make administration a lot easier.

I'm including a word document that also describes configuring SSH on hpux. Hope you find it useful.

Rodney,

Is it possible to use SSH with non-password with local-machine/user1 and remote-server/user2 .. cat id_rsa.pub (user1) >> ~/.ssh/authorized_keys (user2)

then ssh user2@remote-machine 'commands'

[Jannik]

It works perfectly with localhost.

Another smart tool is cfengine. You have to configure and program it, but if you make it work it is realy a time saver.

cd .ssh
cat id_dsa.pub >> authorized_keys
ssh localhost
or
ssh localhost "command;command;command"

as you will se it works. If it should by change not work, you will have to make changes in you sshd_config.

[Jannik]

ups and to change user:

host1 -> localhost (user1):
ssh localhost "command"
ssh -l user2 localhost "command"
or
ssh user2@localhost "command"

from host1 to host2 (remote - user1)
ssh host2 "command"
ssh -l user2 host2 "command"
or
ssh user2@host2 "command"

You just have to have all the keys in place.
You could alsow use the local machine name instead of the localhost. That would make it nice from a scripting point of view.

#!/usr/bin/ksh
SERVERS="s1 s2 s3 s4"
for i in $SERVERS
do
ssh -l root $i "command"
if [ $i = "s1" ]
then
ssh -l user1 $i "command"
fi
done

Hi Jannik,

My question is about using two different users : user1 on localhost and user2 on remote machine.

[Jannik]

That is no problem.
The thing is that the pub file authenticate with user specified in the pub file to a given remote server and user.

if you are userlocal...

cd ~/.ssh
cat id_dsa.pub >> authorized_keys

and to copy to remote.
cd ~/.ssh
scp ./id_dsa.pub remoteserver:/tmp
ssh -l userremote remoteserver "cat /tmp/id_dsa.pub >> ~/.ssh/authorized_keys; rm
/tmp/id_dsa.pub"
YOU HAVE TO TYPE PASSWORD 2 TIMES...

Now you are ready for the script:

#!/usr/bin/ksh
# filename : /usr/local/bin/ssh_script.ksh
# this will work without password

SERVERS="localserver remoteserver1 remoteserver2"

for i in $SERVERS
do
if [ $i = "localserver" ]
then
ssh -l localuser $i "command"
else
ssh -l remoteuser $i "command"
fi
done

I use expect> to do exactly that. the SSH portion doesn't fly well when trying to use SSH with an expect script.. the best method would be to exchange key set with ssh-keygen.

Then with a script you would be required to interact with the shell.. If you want to automate some type of file activity expect will give you the best results.

Does any one know where I can download BINARY Expect for HP-UX 11.0 (Server K Familiy) ?
