Windows Server is one of operating server that use for server usage. Windows server is brand of Microsoft that release since April, 2003. The last version of windows server is Windows Server 2012 R2.

The another version of Windows Server but are not part of Windows Server Family and build for server computer are:
#1 Windows MultiPoint Server: that having many simultan local users

#2 Windows Home Server: use for home example for backup automatically, video streaming, and file sharing for many user

Maybe many improvement but that's all that i know

Sometime you must your internet provider for check what network support for email server:

# traceroute -n -T -p 25 gmail-smtp-in.l.google.com

Bind is great DNS software. If you want to install follow this intruction:

apt-get update
apt-get upgrade
apt-get install bind9
/etc/init.d/apparmor teardown
update-rc.d -f apparmor remove
wget --user=ftp --password=ftp ftp://ftp.rs.internic.net/domain/db.cache -O /etc/bind/db.root
Change/Add this line in /etc/bind/named.conf.option in option{}
allow-query { any; };

allow-recursion { any; };

forwarders {

8.8.8.8;

8.8.4.4;

};

dnssec-validation no;
/etc/init.d/bind9 restart
update-rc.d bind9 defaults

Done thank's

Pernah ketemu problem kaya gitu?

Postgresqlnya ga bisa hidup...nyebelin kan..

Trus Gimana?

Kurangi nilai max_connections pada postgresql.conf
Tambahkan nilai kernel.shmmax dan kernel.shmall pada /etc/sysctl.conf
#sysctl -p
service postgresql start
FINISH

Lebih detil lihat disini: http://www.postgresql.org/docs/7.4/static/kernel-resources.html

Bypass login with setting /var/lib/pgsql/data/pg_hba.conf From "MD5" to "ident" (REMEMBER!: return back after finish), example:
local all all ident
host all all 127.0.0.1/32 ident
host all all 0.0.0.0/0 md5
host all all ::1/128 ident
service postgresql restart
su postgres
psql
ALTER USER postgres WITH ENCRYPTED PASSWORD 'password';
\q
exit
service postgresql restart

# vim /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

# sysctl -p

For Solve that problem:

# echo "" > /etc/udev/rules.d/70-persistant-net.rules
# vim /etc/sysconfig/network-scripts/ifcfg-eth0 # reboot

$sql="INSERT INTO pollquestion (question,pollID,dtcreated,dtmodified) values (".
tosql($txtquestion,"Text").", ".
tosql($pollid,"Number").", ".
"Now(),Now())";
$svdb=clone $db;
$svdb->query($sql.' RETURNING questionid');
$svdb->next_record();
$qid=$svdb->f("questionid");

and you can try:
$this->master_conn->PO_Insert_ID('announcement','modid');
=>> 'announcement': table name
=>> 'modid': an increment id

To solve that: clear the spaces between the commas in sql query PHP or you can add/change to:
utf8_encode($variabel);

1. Lebih detail lihat file gxw410x_interop_asterisk.pdf
2. Pada sip sip.conf tambahkan/ubah
dtmfmode=rfc2833
allow=ulaw
allow=gsm
# include sip_additional.conf
3. Buat sip_additional.conf pada directory /etc/asterisk dan isi dengan (terlampir)
Point penting:
[gxw410x]
type=peer
dtmfmode=rfc2833
context=jadwal
host=gxw410x_ip_address
insecure=port
4. Setting grandstream:
On the GXW410x, under FXO Lines web configuration page set the following:
1. Wait for Dial-Tone(Y/N) to N.
2. Stage Method(1/2) to 1.
3. Unconditional Call Forward to VoIP: The user should construct a valid URI where to
forward the call. The User ID can be the extension number like ch1-4:200; The SIP
server will be using the IP address or FQDN indicated in the profile page, we use p1 for
profile1, p2 or profile2 and p3 for profile3. The SIP destination port should be the one
where the Asterisk is listening for incoming SIP communication.

DTMF Method (1-7): ch1-8:2
2 artinya adalah dtmfmode=rfc2833 (supaya dapat merespon key press dari telepon analog)
Buat dialplan di extensions_additional.conf dengan menambahkan
# include extensions_additional.conf
pada extensions.conf
5. Setting musiconhold.conf:
[default]
mode=files
directory=/var/lib/asterisk/moh
sort=random
6. Masukan musik ke dalam =/var/lib/asterisk/moh yang dapat di download di http://downloads.asterisk.org/pub/telephony/sounds/ cari yang moh gsm
7. Untuk masuk CLI: # asterisk –vvvr
8. Untuk apply konfigurasi: CLI > reload
9. Untuk hangup telepon yang belum ditutup: CLI > hangup request SIP/xxxxxx

This is Differences Postgresql Script and Mysql Script

mysql: SHOW DATABASES
postgresql: \l
postgresql: SELECT datname FROM pg_database;

mysql: SHOW TABLES
postgresql: \d
postgresql: SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';

mysql: DESCRIBE TABLE
postgresql: \d+ table
postgresql: SELECT column_name FROM information_schema.columns WHERE table_name ='table';

mysql: SHOW COLUMNS
postgresql: \d table
postgresql: SELECT column_name FROM information_schema.columns WHERE table_name ='table';

mysqldump -u [username] -p -t -T/tmp [database] --fields-enclosed-by=\" --fields-terminated-by=,

If you have problem don't change /tmp directory :-)

and this is an output (example):

"1","Nur Cholikul","Anwar","2000-01-01 01:01:01"
"2","Putri","Yuniartis"," 2000-01-01 01:01:01 "
"3","Jaringan","Kantor"," 2000-01-01 01:01:01 "

Misalkan:
Ada Dua buah angka yang berada di A1 dan B1 untuk hasilnya ditampikan pada C1
| A | B | C |
1 | 12 | 16 | 3:4 |

Maka rumus untuk C1 adalah:
=IF(OR(A1=0, B1=0),A1&":"&B1,(A1/GCD(A1,B1))&":"&(B1/GCD(A1,B1)))

GCD: digunakan untuk mencari FPB (Faktor Persekutuan Besar)

Suppose that:
There are Two numbers are in A1 and B1 to C1 results are displayed in

| A | B | C |
1 | 12 | 16 | 3:4 |

Then the formula for C1 is:
= IF (OR (A1 = 0, B1 = 0), A1 & ":" & B1, (A1/GCD (A1, B1)) & ":" & (B1/GCD (A1, B1)))

GCD: used to find gcd (a factor of the Great Guild)

Salam damai selalu,

NCA :-)

Example you have a folder or file name at /home

abdillah fauzan kjbi rosmaniar
adbis fehmeed kji sekretariat
admin fikri kmk sekretariatpd1
admniaga grafika kopma sekretariatpd2
agah gretha ksa sekretariatpd3
agung hani ksm sekretariatpd4

and then you want that folder/file get owner same as folder/file name.

Try this:

cd /home
Type at terminal:
for file in *; do
chown -R $file'.pnj' $file;
done
Finish :-)
