Our shops server runs SCO Openserver 5 release 5. It has two network cards in it (one on 10.0.0.6 and one on 90.0.0.99). When I run scoadmin and look at the network settings it show both my 3com network cards and a loop back driver http://theentertainer.com/james/untitled.jpg

Hi,
I'm looking for a command to be able to disable a network card under the boot PROM.
I need it to force my Jumpstart to use the Ethernet card of my server (V880) instead of my fiber card (gem0).
Thanks,

Hi,
I'm looking for a command to be able to list all my network cards available on my server.
With the command "ifconfig - a", I can only see to configured network card(s)
Any idea ? :confused:
Thanks a lot for your help,

The title speaks for itself. I have never attempted this but understand there is a way to use two network cards (en0 and en1) with the same IP address so as to load balance the traffic flow through both cards. Anyone know the answer? (4 Replies)
Hi All,
Hope you are all doing good.
In MY unix box i have 2 network cards. I want to know what if one network card fails. Does the second one will automatically take all the traffic or how it is supposed to work. Also in my logs i am seeing below errors . Can you throw some light of this qfe... (3 Replies)
Hi all
I hate networking, I hate everything to do with it. Its something I do in anger in one contract, then forget. This is more of a question / than a problem.
So, on a solaris 10 server, using older qfe cards, Ive got a sun truck with 4 nics (qfe0,3,4,7), and a ipmp pair (hemo0,qfe1).... (2 Replies)
Hello everybody,
I'm having troubles with Slackware 13.1 and network cards.
I have one on-board Ethernet card (which is recognized and works okay) and a PCI Ethernet card (which is also recognized, but doesn't appear in 'ifconfig -a'). If i run a 'lspci', i can see the kernel recognized the... (5 Replies)
Im trying to use wild cards to find files that start with either an upper or lower case letter e.g. list files that beginning with b or B, i also want to sort them by the time they were last modified. e.g latest file created first.

Hi All,
I have just setup a webserver running on a linux box. This server has 2 ethernet cards and only 1 is in used now. eg. 192.168.10.1 is my server IP. All users from 192.168.10.X can access my webserver. However, users from another LAN 10.10.10.X are not able to access my webserver. They... (0 Replies)

net::netent
Net::netent(3pm) Perl Programmers Reference Guide Net::netent(3pm)NAME
Net::netent - by-name interface to Perl's built-in getnet*() functions
SYNOPSIS
use Net::netent qw(:FIELDS);
getnetbyname("loopback") or die "bad net";
printf "%s is %08X
", $n_name, $n_net;
use Net::netent;
$n = getnetbyname("loopback") or die "bad net";
{ # there's gotta be a better way, eh?
@bytes = unpack("C4", pack("N", $n->net));
shift @bytes while @bytes && $bytes[0] == 0;
}
printf "%s is %08X [%d.%d.%d.%d]
", $n->name, $n->net, @bytes;
DESCRIPTION
This module's default exports override the core getnetbyname() and getnetbyaddr() functions, replacing them with versions that return
"Net::netent" objects. This object has methods that return the similarly named structure field name from the C's netent structure from
netdb.h; namely name, aliases, addrtype, and net. The aliases method returns an array reference, the rest scalars.
You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that
this still overrides your core functions.) Access these fields as variables named with a preceding "n_". Thus, "$net_obj->name()"
corresponds to $n_name if you import the fields. Array references are available as regular array variables, so for example "@{
$net_obj->aliases() }" would be simply @n_aliases.
The getnet() function is a simple front-end that forwards a numeric argument to getnetbyaddr(), and the rest to getnetbyname().
To access this functionality without the core overrides, pass the "use" an empty import list, and then access function functions with their
full qualified names. On the other hand, the built-ins are still available via the "CORE::" pseudo-package.
EXAMPLES
The getnet() functions do this in the Perl core:
sv_setiv(sv, (I32)nent->n_net);
The gethost() functions do this in the Perl core:
sv_setpvn(sv, hent->h_addr, len);
That means that the address comes back in binary for the host functions, and as a regular perl integer for the net ones. This seems a bug,
but here's how to deal with it:
use strict;
use Socket;
use Net::netent;
@ARGV = ('loopback') unless @ARGV;
my($n, $net);
for $net ( @ARGV ) {
unless ($n = getnetbyname($net)) {
warn "$0: no such net: $net
";
next;
}
printf "
%s is %s%s
",
$net,
lc($n->name) eq lc($net) ? "" : "*really* ",
$n->name;
print " aliases are ", join(", ", @{$n->aliases}), "
"
if @{$n->aliases};
# this is stupid; first, why is this not in binary?
# second, why am i going through these convolutions
# to make it looks right
{
my @a = unpack("C4", pack("N", $n->net));
shift @a while @a && $a[0] == 0;
printf " addr is %s [%d.%d.%d.%d]
", $n->net, @a;
}
if ($n = getnetbyaddr($n->net)) {
if (lc($n->name) ne lc($net)) {
printf " That addr reverses to net %s!
", $n->name;
$net = $n->name;
redo;
}
}
}
NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
