Hi all!
I have problem with copying files from tape drive.

Hi all,
I'm setting up a VM on our ESX server using Sun 10 x86. I've configured the hostname in Sun 10, but no other machine is able to use the hostname to communicate with it (i can however use its IP address)
hostname is set in the /etc/nodename file
my resolv.conf looks like

Hi all,
First I know little about ipv6.
I have two target. A and B,A and B connet with each other *directly* with line.and I can ping each other with ipv4
For A:

membar_producer
MEMBAR_OPS(3) BSD Library Functions Manual MEMBAR_OPS(3)NAME
membar_ops, membar_enter, membar_exit, membar_producer, membar_consumer, membar_sync -- memory access barrier operations
SYNOPSIS
#include <sys/atomic.h>
void
membar_enter(void);
void
membar_exit(void);
void
membar_producer(void);
void
membar_consumer(void);
void
membar_sync(void);
DESCRIPTION
The membar_ops family of functions provide memory access barrier operations necessary for synchronization in multiprocessor execution envi-
ronments that have relaxed load and store order.
membar_enter()
Any store preceding membar_enter() will reach global visibility before all loads and stores following it.
membar_enter() is typically used in code that implements locking primitives to ensure that a lock protects its data.
membar_exit()
All loads and stores preceding membar_exit() will reach global visibility before any store that follows it.
membar_exit() is typically used in code that implements locking primitives to ensure that a lock protects its data.
membar_producer()
All stores preceding the memory barrier will reach global visibility before any stores after the memory barrier reach global visibility.
membar_consumer()
All loads preceding the memory barrier will complete before any loads after the memory barrier complete.
membar_sync()
All loads and stores preceding the memory barrier will complete and reach global visibility before any loads and stores after the memory
barrier complete and reach global visibility.
SEE ALSO atomic_ops(3)HISTORY
The membar_ops functions first appeared in NetBSD 5.0.
