Добавяне на VLAN интерфейс в линукс.
VLAN Network Interface in Linux.

Ако правим виртуалния интерфейс на eth0, правим така:
# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0.10

Това копира конфигурационния файл на eth0 в eth0.10
Тук някъде някой може би започва да се досеща, че тази цифра 10 е на практика VLAN тага.

Следва редактиране на конфигурационният файл за новият интерфейс:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0.10
Променяме
DEVICE=ifcfg-eth0.10
Добавяме
VLAN=yes

И рестартираме мрежата:
# /etc/init.d/network restart

Другият вариант е следният:
# vconfig add eth0 10
# ifconfig eth0.10 192.168.1.1 netmask 255.255.255.0

За да изтриете създаден VLAN:
# ifconfig eth0.10 down
# vconfig rem eth0.10

Честито!

Generating SSL certificates for Apache:

# cd /etc/httpd
# openssl req -newkey rsa:1024 > server.csr

Remove key's password (optional):
# openssl rsa -in privkey.pem -out /etc/httpd/ssl.key/server.key

Creating the actual signed certificate:
# openssl x509 -in /etc/httpd/ssl.csr/server.csr -out server.crt -req -signkey /etc/httpd/ssl.key/server.key -days 3650

Solaris 10 SNMP:

Configuration file:
/etc/sma/snmp/snmpd.conf

restart the sma (system management agent):
# svcadm restart svc:/application/management/sma:default

To view the status of the agent:
# svcs svc:/application/management/sma:default

Reset Sun ALOM password:

For user admin

# cd /usr/platform/`uname -i`/sbin
# ./scadm userpassword admin

Dump postgresql database to file:

pg_dump -U databaseuser -W database > dump.sql

Restore postgresql dump:

psql -U databaseuser database < dump.sql

In file included from Keyfile.cpp:10:

Durring TrueCrypt installation, do this:

# wget ftp.rsasecurity.com/pub/pkcs/pkcs-11/v2-20/pkcs11.h

SSL support for Apache 2.0.x on FreeBSD 7.1

Creating directories:
# mkdir /usr/local/apache2/conf/ssl.key
# mkdir /usr/local/etc/apache2/ssl.crt
# mkdir /usr/local/etc/apache2/ssl.crl

Creating 10 years valid certificate:
# openssl req -new -x509 -days 3650 -keyout /usr/local/etc/apache2/ssl.key/server.key -out /usr/local/etc/apache2/ssl.crt/server.crt

Starting apache with ssl:
# apachectl startssl
(It asks for the pass key)

To remove the pass key:
# cd /usr/local/etc/apache2/ssl.key
# cp server.key server.key.orig
# openssl rsa -in server.key.orig -out server.key

Problem
-------
How do I change the timezone on my Solaris server/workstation?

Solution
--------
a) Edit /etc/TIMEZONE
NOTE: the man page incorrectly states this file is called /etc/timezone
b) Reboot your server with shutdown or init.


Examples
--------
US/Eastern
US/Central
US/Mountain
US/Pacific

For the full list, look in:
/usr/share/lib/zoneinfo/

Create hardware RAID1 on Sun Solaris

# raidctl -c c1t0d0 c1t1d0

c1t0d0 is the system drive on which the OS is installed. It will be the master drive. The second will be wiped.

Enabling the cache for this array:

# raidctl -p "wp=on" c1t0d0

Installing Oracle 10 on Solaris 10 SPARC

Create oracle user account:

# useradd -c "Oracle Owner" -d /export/home/oracle oracle

Edit [create] .bash_profile file in oracle user home directory:

ORACLE_HOME=/export/home/oracle/oracle/product/10.2.0; export ORACLE_HOME
ORACLE_SID=QUO1; export ORACLE_SID
TNS_ADMIN=/export/home/oracle/config/10.2.0 export TNS_ADMIN
ORA_NLS10=${ORACLE_HOME}/nls/data; export ORA_NLS10
CLASSPATH=${CLASSPATH}:${ORACLE_HOME}/jdbc/lib/classes12.zip
ORACLE_TERM=xterm; export ORACLE_TERM
ORACLE_OWNER=oracle; export ORACLE_OWNER
#NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1; export NLS_LANG
LD_LIBRARY_PATH=/usr/lib:${ORACLE_HOME}/lib:${ORACLE_HOME}/lib32; export LD_LIBRARY_PATH

# Set up the search paths

PATH=/usr/local/bin:/usr/local/sbin:/sbin:/usr/sbin:/usr/sfw/sbin
PATH=$PATH:/usr/bin:/usr/ccs/bin:/usr/openwin/bin:/usr/sadm/bin
PATH=$PATH:/usr/sfw/bin:/usr/X11/bin:/usr/j2se/bin
PATH=$PATH:$ORACLE_HOME/bin

This is added to /etc/system:

set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100

set semsys:seminfo_semmns=1024
set semsys:seminfo_semmsl=256
set semsys:seminfo_semmni=100
set semsys:seminfo_semvmx=32767
set noexec_user_stack=1

Create default project for oracle user:

# projadd -U oracle -K "project.max-shm-memory=(priv,4096MB,deny)" user.oracle
# projmod -s -K "project.max-sem-ids=(priv,256,deny)" user.oracle

$ cpio -idcmv < filename.cpio

Start the installation:

$ ./runInstaller

Adding a Swap File on Solaris:

Creating the file:

# /usr/sbin/mkfile 1024m /swap

# /usr/sbin/swap -a /swap

Absolute path to the swap file must be given.
