If you want automatic upgrade all of ports excluding one, then go to the /var/db/pkg/oneofinstalledport and cerate empty file +IGNOREME
# touch +IGNOREME
Other systems:
Arch Linux: use IgnorePkg in /etc/pacman.conf
Search: Skip package from being upgraded
Chcielibyśmy aby maile zawierające w w polu adresat (to:) ciąg znaków “spam” były przekierowaywne na skrzynkę danego usera
# vi virtual-regexp
/^spam/ user
# vi main.cf
virtual_maps=hash:/usr/local/etc/postfix/virtual, regexp:/usr/local/etc/postfix/virtual-regexp
# postmap virtual-regexp
$ man regexp_table
Co dzięki temu uzyskaliśmy?
Możemy na różnych serwisach które wysyłają nam masę maili czasem potrzebnych czasem mniej, tworzyć dedykowany adres spamerski w stylu spam.facebook@, spam.twitter@ i filtrować maile tylko po adresacie (recipient) a nie wysyłającym (sender)
type in command line
:mkvimrc! $HOME/.gvimrc
if you encountered in dmesg output entry such as:
CPU0: local APIC error 0x2
add this to /boot/device.hints
hint.apic.0.disabled="1"
the problem should disappear
because I found my first CD
if you occured server panic on FreeBSD 9.2 using journaled soft updates you probably had not clean shutdown and there is some inconsistency (though filesystem is clean) – for better stability disable journaled soft updates:
boot into single mode and after full fsck do:
# tunefs -j disable /dev/filesystem # reboot
or if you want to using journaled soft updates do manual fsck in single user mode without using journal
# USE JOURNAL? [yn] n
then the server panics should not appear to the next unclean shutdown…
if you obtain:
ping: socket: Operation not permitted
although:
security.jail.allow_raw_sockets=1
is set in /etc/sysctl.conf
you should add an option in the rc.conf
jail_yourjailname_parameters="allow.raw_sockets=1"
or add this option in /etc/jail.conf if you are using new configuration scheme added in FreeBSD 9.1 – see man jail.conf
