I asked a similar question earlier and got a very good answer but a new doubt came up. This is a few lines of a '/sbin/ifconfig' command on my PC:
RX packets:3781025 errors:0 dropped:0 overruns:0 frame:0
TX packets:1941909 errors:0 dropped:0 overruns:0 carrier:0
Does the RX and TX packets... (1 Reply)

This will most likely be a real dumb question for a HP-UX admin, but here it goes anyhow.
lan0 - is up and configured
lan1 - is down, I want to bring it up.
lanconfig....ifconfig is there a difference?
My real question is, in solaris there is an /etc/hostname."?" file, is there a... (4 Replies)
I am trying to change an IP address on a machine running HPUX10
After I change it I can ping it from the outside but it completely locks the console. After a reboot it returns back to its previous IP. Any ideas??
Thanks

On prior versions to solaris 10 when I want to add/change the IP address of an interface I will use this command.
ifconfig eri0 down
ifconfig eri0 192.xxx.xxx.xxx netmask 255.xxx.xxx.xxx up
then change /etc/hosts so that /etc/hostname.eri0 picks up on the correct IP.

I have a script problem that I am not able to solve due my very limited understanding of unix/awk.
This is the contents of test.sh
awk '{print $1}'
From the prompt if I enter:

I would expect to see "Hello" but all I get is a blank line. Only then if I enter "Hello... (2 Replies)

io::async::signal
IO::Async::Signal(3pm) User Contributed Perl Documentation IO::Async::Signal(3pm)NAME
"IO::Async::Signal" - event callback on receipt of a POSIX signal
SYNOPSIS
use IO::Async::Signal;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $signal = IO::Async::Signal->new(
name => "HUP",
on_receipt => sub {
print "I caught SIGHUP
";
},
);
$loop->add( $signal );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a particular POSIX signal is received.
Multiple objects can be added to a "Loop" that all watch for the same signal. The callback functions will all be invoked, in no particular
order.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_receipt
Invoked when the signal is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
name => STRING
The name of the signal to watch. This should be a bare name like "TERM". Can only be given at construction time.
on_receipt => CODE
CODE reference for the "on_receipt" event.
Once constructed, the "Signal" will need to be added to the "Loop" before it will work.
