Homework and Emergencies Homework & Coursework Questions Accessing one UNIX node from another node of the same server Post 302879706 by vipinkumarr89 on Saturday 14th of December 2013 04:09:00 AM

Hi,
What i understood from your question : you want to list the file on node 1, but you want to trigger it from node 2 because you don't have scheduling tool in node 1.
In this case we need to write a script on node 1(this scirpt will wait for a signal from node 1).

1> Set the crontab in node 2(where you have access to crontab, if you don't have access to crontab you can write a script to send email to node 1 ) to send an email to node 1.
2> Write a script in node 1 to check for a new email, if new email is available in node 1, execute the command (whatever you want to execute).
If you need help with script, let me know.

trigger(8)						      System Manager's Manual							trigger(8)

Name
       trigger - trigger a target node to request a down-line load

Syntax
       /etc/trigger node [ options ]

Description
       The command triggers the bootstrap mechanism of a target node, causing the target to request a down-line load.  Once a target node is trig-
       gered, it loads itself in whatever manner its primary loader is programmed to operate.  The target node could request a down-line load from
       the host that just triggered it or from another adjacent node, or the target node could load itself from its own mass storage device.

       The  node argument is the name or address of the target node.  A node name consists of from one to six alphanumeric characters.	For single
       networks, a node address consists of a decimal integer (1-1023).  For multiple networks, a node address consist	of  two  decimal  integers
       (n.n), where the first indicates the network number (1-63), and the second indicates the node address (1-1023).

       The  command requires the identification of the service circuit over which the load is performed, the Ethernet hardware address of the tar-
       get node, and the service password needed to gain access to the target.	This information is included in the nodes database entry  for  the
       target node.  A node entry is defined with the command.	For further information, see Alternatively, you can choose not to include a target
       node's service password in the nodes database for security reasons.  You must therefore specify this value in the command line by using the
       -p option.

Options
       -p     Uses the specified service and password (next arguments) in accessing the target node.

Examples
       This command triggers node Bangor to issue a down-line load request:
       # /etc/trigger bangor <RET>
