На Gnome когато изключвам машината ми дрънчи следния прозорец

"
gnome-keyring-daemon
not responding
"

С други думи keyring-a не се shutdown-ва нормално. Ето го и решението:

killall -9 gnome-keyring-daemon
rm -rf ~/.gnome2/keyrings

Идеята е, че с VIM когато използвам шел "!sh" не ми прави допълване на командите с TAB за да се оправи това трябва да се коригира подразбиращия шел shell (него ползва vim shell). В моя случай е dash. Избран е този понеже от към бързина е по- добър от bash именно заради липсата на автоматично дописване. Сега ще го премахнем като default shell:

sudo dpkg-reconfigure dash

Избиране "No" и сме готови :)

Проблема е, че при логване с ssh към машина извежда следното съобщение:

Виждаме, че времето от 15 секунди се свеждо до 5 секунди.

За се запише за постоянно се редактира файл: /etc/ssh/ssh_config
и стойността на "GSSAPIDelegateCredentials" се прави на "no"

Прави се заявка за изтриване на всички таблици започващи с oc от база "comptech":

SELECT CONCAT("DROP TABLE ",GROUP_CONCAT(TABLE_NAME)) AS stmt FROM information_schema.TABLES WHERE
TABLE_SCHEMA = "comptech" AND TABLE_NAME LIKE "oc%";

Прави се заявка за изтриване на всички таблици от база "comptech" с изключение на foo,bar,baz

SELECT CONCAT('DROP TABLE ', TABLE_NAME, '; ')
FROM information_schema.tables
WHERE table_schema = 'comptech' AND table_name NOT IN ('foo', 'bar', 'baz');

Идеята е на форум Vbulletin с userid ='1' да се сетна парола 'parola'(това е администратора):

UPDATE user set password = MD5(concat(MD5('parola'), user.salt)) WHERE userid = 1

Ако таблицата има префикс:

UPDATE labuser set password = MD5(concat(MD5('parola'), labuser.salt)) WHERE userid = 1

Когато се логвах на една машина на един приятел през SSH получих следните грешки. По- долу съм описал и техните решения.

Грешка 1: ssh_exchange_identification: Connection closed by remote host

Решение: Да се проверят следните файлове
/etc/hosts.deny и /etc/hosts.allow

Грешка 2: PTY allocation request failed on channel 0

Решение 2: rm -rf /dev/ptmx;mknod /dev/ptmx c 5 2;chmod 666 /dev/ptmx;umount /dev/pts;rm -rf /dev/pts;mkdir /dev/pts;mount /dev/pts;

Основни пакети

1. yum install ImageMagick.i386
2. yum install ImageMagick-devel.i386
3. pecl install imagick

4. След като се инсталира imagick трябва да се зареди в php.ini
Kомпилирания модул може да се намери в /usr/lib/php/modules .

echo 'extension=imagick.so' >>  /etc/php.ini

6. Рестартиране на apache2

/etc/init.d/httpd restart

7. Проверяване дали всичко е инсталирано правилно:

Прави се файл info.php със съдържание:

<?php phpinfo(); ?>

Ако всичко е наред вътре ще има секция "imagick"
