Executing a script on a remote system via SSH
Hello all,

I have a relatively simple script I wrote to generate a count of errors broken down. What I would like to do is execute this script from another server so that I don't actually have to log in to the server to run the check.

The script on what we'll call "Server A" is:

Code:
#!/usr/bin/bash
######################################################
# Program:      last18s.sh
# Date Created: 8 November 2008
# Developer:    XXXX (Digital Sys. Admin)
# Description:  Generates Service groups throwing error 18's with a given threshold
######################################################
if 
[ "$1" = "" ]; then
echo "Usage: last18s.sh <number of error 18's back you wish to check for>"
else
tac /usr/local/n2bb/log/n2bb.log|grep 0x12|head -$1|awk '{print "Service group = "$19}'|sort -n|uniq -c|tr -d "."
fi
root@bms02-twc-NM-newyork-ny:/root#

I can run this script directly from "Server B" by just entering:

18:44:29\[ddecosta@N.Man)
[~/bin]$ ssh root@10.241.1.52 'last18s.sh 10'
Password:
4 Service group = 11559

but once I try putting this in a simple script, it stops workig:

Code:
(18:49:00\[ddecosta@N.Man)
[~/bin]$ cat last18s.sh 
#!/usr/bin/bash
ssh root@10.241.1.52 'last18s.sh $1'

(18:49:32\[ddecosta@N.Man)
[~/bin]$ last18s.sh 10
Password:
Usage: last18s.sh <number of error 18's back you wish to check for>

Is there not a way to pass variables through the SSH?

tentacle_client

TENTACLE_CLIENT(1)					   Client file transfer protocol					TENTACLE_CLIENT(1)

NAME

       tentacle_client - a client file transfer protocol

SYNOPSIS

       tentacle_client <options> Tentacle is a client/server file transfer protocol that aims to be:

       -   Executable programs or shell commands
       -   System calls (functions provided by the kernel)
       -   Library calls (functions within program libraries)

       Tentacle  was  created  to  replace  more complex tools like SCP and FTP for simple file transfer/retrieval, and switch from authentication
       mechanisms like .netrc, interactive logins and SSH keys to X.509 certificates. Simple password authentication over a SSL secured connection
       is supported too.

       The  client  and  server  (TCP port 41121) are designed to be run from the command line or called from a shell script, and no configuration
       files are needed.

       Tentacle is now the default file transfer method for Pandora FMS and Babel Enterprise.

       Tentacle is implemented in Perl and ANSI C (Windows platforms included).

       You can download it and get more information at the official Sourceforge website http://tentacled.sourceforge.net/.

OPTIONS

       Tentacle Client options :
	      -a address : Server address (default 127.0.0.1).
	      -c : Enable SSL without a client certificate.
	      -e cert : OpenSSL certificate file. Enables SSL.
	      -f ca : Verify that the peer certificate is signed by a ca.
	      -g : Get files from the server.
	      -h : Show help.
	      -k key : OpenSSL private key file.
	      -p port : Server port (default 41121).
	      -q : Quiet. Do now print error messages.
	      -r number : Number of retries for network operations (default 3).
	      -t time : Time-out for network operations in seconds (default 1s).
	      -v : Be verbose.
	      -w : Prompt for OpenSSL private key password.
	      -x pwd : Server password.

EXAMPLES

       tentacle_client -a 192.168.1.1 -v /bin/bash
	      Simple file transfer with maximum file size set to 1MB

       tentacle_client -a 192.168.1.1 -x password -v /bin/bash
	      Simple file transfer with password authentication (not secure)

       tentacle_client -a 192.168.1.1 -x password -e cert.pem -k key.pem -v /bin/bash
	      Secure file transfer with client certificate and password authentication

NOTES

       Tentacle requires Perl 5.8 or higher to works
