Help me: How to execute script in a remote host

[Hoang Chi Cong_1]

Hi all
I am really stuck with this case:
I have three servers (HP-UX 11.i): ServerA, ServerB and ServerC
I have username "opr1" in all servers and I can login each other with rlogin.

Now, from serverA (with "opr1" user)I want to make a script that copy a file from serverC to ServerA and then update that file. After that, copy that file from ServerA to ServerB and then execute a script to update this file again.
The script like:

# Copy a file "file_name" from ServerC to ServerA
rcp -p ServerC:/apps/file_name /apps/
{
Update "file_name"......
..........
..........
}
# Copy file "file_name" from ServerA to ServerB

??????
??????
# Execute a script to update this file in ServerB
?????
?????

Please help me!
Thanks in advance.

Hi Hoang,

Update you /etc/hosts.equiv, and .rhosts files which will enable you to remote login and remote copy.

Then remote copy the file using rcp

change the directory to where you want to copy

rcp â p hostname:/path/filename .

edit the file

then copy back to the other server

rcp filename hostname:/path/

Hi,

First of all, you have to provide rcp and remsh execution without a password request by editing ~opr/.rhosts on serverB and serverC (add ServerA hostname into the file).
Let's suppose that the script which updates the file called /apps/update.sh
#Copy a file "file_name" from ServerC to ServerA
rcp -p ServerC:/apps/file_name /apps/
#Update "file_name"
/apps/update.sh
# Copy file "file_name" from ServerA to ServerB
rcp -p /apps/file_name serverB:/apps/.
# Execute a script to update this file in ServerB
remsh serverB /apps/update.sh

Best

Thanks all for your replies...

Now I want to execute a script in ServerB from ServerA.
I can use
<>remsh ServerB ls

But I can not execute a script in ServerB from ServerA:
<>remsh ServerB /tmp/myscript.sh
The screen out put:
ksh: /tmp/myscript.sh: not found


Has any idea?

Hi,
The script you to execute need to be in the server, that will be executed.
Put /tmp/myscript.sh in the ServerB, check that have permissions to execute. If you can to that command without asking for password the schema it's the correct:
# rmsh ServerB date
or
# rmsh ServerB -l user date


Good luck,
Joel

Hi,

you have to put the script first to this serverB:
<>rcp /apps/file_name ServerB:/tmp/myscript
Note, that there my be no execution bit set on this script, so better call the shell directly:
<>remsh ServerB sh /tmp/myscript.sh

Seem it works...
But there are some command (application command) in the script doens't work :-(

It said: not found???

[A. Clay Stephenson · Accepted solution]

If you are seeing "not found" then it means just what it says. The command is not in your PATH on the remote machine. This really means that if you are executing /xxx/yyy/zzz.sh on the remote machine then /xxx/yyy/zzz.sh needs to explicitly set and export any needed environment variables including PATH itself.

[Hoang Chi Cong_1]

Hm...I really forgot it...Yes...the PATH.
I will set now...
Thanks A. Clay Stephenson.
Have a nice weekend :)
