execute rlogin with local script

Cesar Gonzalez_1 — Fri, 01 Feb 2002 13:33:21 GMT

Hi. I??ve got many servers (B,C,D,E..) and a script in A server. Are there any way to execute that script from server A to the others?. If I run remsh, It tries to execute the script from the others servers, not from MY A. It would be bothersome to ftp script in all servers...
Thanks in advance

if you have rights, why not,...

# On server A
for i in B C D E
do
rcp /tmp/script1 $i:/tmp
remsh $i -c "/tmp/script1"
done

If access rights are the other way, instead of an 'rcp', perform a 'remsh -c 'rcp A:/tmp/script1 /tmp''

Share and Enjoy! Ian

Hi,

You could try to share a single directory from A where you save the script and mount this share on all the other machines.
Then you don't need to ftp the script to the other machines.

Hi Cesar,

If the script is not too complicated, you should be able to:

cat script | remsh host "/sbin/sh"

Rgds, Robin

# On all servers B C D E
in your home directory create .rhosts with the following entry:
A username

After this do what listed below:

for i in B C D E
do
rcp /tmp/script1 username@$i:/tmp
remsh $i -l username -n "/tmp/script1"

remsh $i -l username -n " rm /tmp/script1"

done

Bye

I have a similar question as well.

I have scripts that I run to add and delete printers, directories, etc. I don't rerally want to copy the script onto the other machines, (leaves a lot of junk for me to clean up). Can I execute the script from server A on servers BCD and E without copying it over? I don't really want to NFS mount drives to my servers due to security considerations.

Suggestions?

Jerry,

I don't think you can do this. The essence of the answer to this question was that the Script does have to be on the remote server.

How about creating a 'depot' on all Servers for common scripts? I use '/usr/local/bin' and any scripts I create for one server, I try to rollout to all for future use.

If you really want a clean system with no scripts remaining, federicos answer above gives the perfect solution.

Share and Enjoy! Ian
