I still haven't had chance to read the entire Debian manual, which I promise I will do as soon as I can, and I will start putting info back into this forum.
However, for the mean time, could someone please help with a small script? I understand what I've got to do and how to do it, but I'm struggling with getting the syntax right.
I have a loads of nodes I need to connect to from time to time, but I'm never sure if they're alive. So instead of ssh'ing and waiting ages to either get a connection, or not, I'd sooner start with a ping, if there is a good response, set off the ssh. At this point I might have 10 terminal sessions open for different nodes, so I want to automate as much as possible.
I have a linux box build11 which can be pinged from build18 (Windows) box. And we can only login to the box (using SSH) from build18 box. Plz help to characterize the problem, network, DNS, DHCP, etc (or whatever which I am unsure)
Any idea what may be the reason ? :confused:

Hi,
I am writing a script on Solaris 10 and want to execute a remote ssh command. Normally this command should just return the value 0000000000002356 but when using ssh it seems it is passing the result to the shell to execute.
ssh root@10.5.112.145 `/usr/bin/nawk -F\, '$1=="USG" && $2=="01"... (3 Replies)
I have a Solaris 9 server that does not return a ping. When I try to log in via SSH I eventually get in. I am logged in now.
I know this is a wide open question, but can you recommend some things I should check?

X11::Protocol::Connection - Perl module abstract base class for X11 client to server connections
SYNOPSIS
# In connection object module
package X11::Protocol::Connection::CarrierPigeon;
use X11::Protocol::Connection;
@ISA = ('X11::Protocol::Connection');
sub open { ... }
sub give { ... }

DESCRIPTION
This module is an abstract base class for the various X11::Protocol::Connection::* modules that provide connections to X servers for the
X11::Protocol module. It provides stubs for the following methods:
open
$conn = X11::Protocol::Connection::Foo->open($host, $display_num)
Open a connection to the specified display (numbered from 0) on the specified $host.
give
$conn->give($data)
Send the given data to the server. Normally, this method is used only by the protocol module itself.
get
$data = $conn->get($n)
Read $n bytes of data from the server. Normally, this method is used only by the protocol module itself.
fh
$filehandle = $conn->fh
Return an object suitable for use as a filehandle. This is mainly useful for doing select() and other such system calls.
