Operating Systems SCO network problems with sco Post 302316100 by ajacques on Thursday 14th of May 2009 04:48:03 AM

Hi everyone,

I have the exact same problem with two of my servers running on SCO 5.0.5.

The first one is part of a tiny network (about 6 or 7 'clients') so I don't think the number of TCP connections is the reason. Thanks to your previous posts, we are about to install a packet sniffer on the network.

The problem is that I'm not really a network expert (and my native language is french) so I'm a bit lost in all the information the sniffer will give to me. What am I supposed to search for ? Gratuitous ARP Requests ? I've read that those requests are sent to check for double IP, is it true ?

Thanks in advance

edit : I'm trying to install tcpdump on my server. When I try to launch it, I have en error message : "no cards available to use in /dev/mdi". And when I try to give him the interface I want, it says "Can't open device - Device busy". Do I need to install a second card on the server ?

Name
       ris - remote installation services utility

Syntax
       /etc/ris

Description
       The  utility performs remote installation services which install system software to a client machine through the TCP/IP local network.  The
       client machine can be a VAX or a RISC machine.

       The server on which the remote installation services area is located can be either a VAX or a RISC machine.

       The remote installation services utility uses the directory as a base.  When you install the first product to the utility creates a  remote
       installation services area.  The area is called either or

       The  area contains one or more ULTRIX software products.  Each product contains the subsets of the kits that can be installed to clients on
       a network.  Clients registered for an area install software over the network to their processor.

       The utility performs the following functions:

       a -  Add client

       r -  Remove client

       s -  Show products in remote installation environments

       m -  Modify client

       i -  Install software

       You must use the utility interactively to set up a remote installation services area.  After you have set up a remote installation services
       area on the server, you can use the utility either interactively or from the command line to manage clients.

       The directory also holds a subdirectory, This directory contains a database file, that you can use to manage multiple clients.

Examples
       The example that follows invokes the utility interactively:
       # /etc/ris

       A menu appears from which you can select options to perform functions.

       The examples that follow manage the client using the command line.

       The syntax of the command to add a client follows:
       /etc/ris -a <clientname> -h <Ethernet_address> -p path,product[,product]

       The following command adds client and allows that client to install a product over the network:
       # /etc/ris -a bergal -h 08-00-2B-03-05-8B -p ris0.mips,product_1

       The syntax of the command to modify a client follows:
       /etc/ris -a <clientname> [-h <Ethernet_address>] [-p <path,product,product>]

       The following command modifies client and allows that client to install a product over the network:
       # /etc/ris -m bergal -p ris0.mips,product_2

       The syntax of the command to remove a client follows:
       /etc/ris -r <clientname>

       The following command removes client
       # /etc/ris -r bergal
