Днес гледам не иска да генерира конфигурационни файлове на модемите и какво да направя.

/usr/local/bin/docsis -e /etc/iptraff/172-16-30-18.cfg /tmp/authfile333333555 /tftpboot/172-16-30-18.bin

и гледам извежда следните грешки:

No log handling enabled -- turning on stderr logging

Става ясно, че не зарежда MIB файловете.

По следния метод може да се провери от къде иска да ги зареди

net-snmp-config --default-mibdirs

/root/.snmp/mibs:/usr/share/mibs/site:/usr/share/snmp/mibs:/usr/share/mibs/iana:/usr/share/mibs/ietf:/usr/share/mibs/netsnmp

За да се инсталират mib файловете:

/etc/apt/sources.list

deb http://ftp.debian.org/debian/ squeeze contrib non-free
deb-src http://ftp.debian.org/debian/ squeeze contrib non-free

apt-get update && apt-get install snmp-mibs-downloader

cp -Rvp /var/lib/mibs/ietf/* /usr/share/mibs/netsnmp/

За да заработи всичко просто се слагат необходимите custom(ако са) MIB-ове в папката и това е

Пускаме /usr/local/bin/docsis -e /etc/iptraff/172-16-30-18.cfg /tmp/authfile333333555 /tftpboot/172-16-30-18.bin
и всичко е ОК

MySQL е много бърза, стабилна система за управление на релационни бази данни (Relational Management Systems- RDBMS). Базата данни позволява ефективно съхранение, претърсване, сортиране и извличане на данни. MySQL контролира достъпа до вашите данни и позволява едновременна работа на множество потребители, бърз достъп, както и осигуряване на достъп само на оторизираните за това потребители. …

PS: Готин домейн за дрехи: dreha.bg

Идеята е да се премахнат всички празни редове:

g/^\s*$/d

Друг трик е да се премахне всичко след конкретен символ. Примерно имам следния ред:" Мартин Петров (Мартин" и желая да премахна всичко след "(":

Идеята е да се открият какви dhcp сървъри има в мрежата.

Идяета е да се стартира mysqld които да предлага само четене без запис. Това е подходящо за репликиращи схеми и други.

Първи метод :
1.1

Със Superuser т.е. root сетвамее read_only=1 или read_only=yes

mysql-h localhost-u root-p
set GLOBAL read_only = true;

Със нормален потребител притежаващ пълни права върху конкретна база изпълняваме следната заявка:

mysql> insert into x (c) values ('test_mysql_read_only_by_amri');
ERROR 1290 (HY000): The MySQL server is running with the --read-only option so it cannot execute this statement

За да активираме write правата на всеки нормален потребител(изключение е само root):

mysql-h localhost-u root-p
set GLOBAL read_only = false;

1.2
Във файл /etc/mysql/my.cnf и по- точно в секция [mysqld] се добавя:

[mysqld]
read_only=1

/etc/init.d/mysql restart;

Втори метод за заключване на таблиците само за четене:

2.1
Отварят се две конзоли свързани към mysql. На втората се изпълнява(заключваме):

mysql> FLUSH TABLES WITH READ LOCK;
Query OK, 0 rows affected (0.01 sec)

На първата конзола която също е свързана към mysql се прави опит за INSERT , но не става :)

За да се активира отново на втората конзола се изпълнява:

mysql> UNLOCK TABLES;
Query OK, 0 rows affected (0.00 sec)
