Kirim Email via Console dengan sendEmail

with 4 comments

Mengirim email via console sangat mudah, apalagi jika anda seorang administrator yang memegang sebuah server dimana server anda harus bisa memberitahukan error system setiap saat ke alamat email anda maupun pada orang yang bertanggungjawab pada service yang berjalan. Ada opsi yang sangat mudah karena kita sudah dibantu dengan adanya aplikasi sendEmail yang berbasis bash-scripting dengan bahasa Perl. Cara anda tinggal install terlebih dahulu (based on Ubuntu) :

# aptitude install sendemail libio-socket-ssl-perl libnet-ssleay-perl perl

atau jika tidak menggunakan distro Ubuntu bisa didapat source nya disini

cara installnya seperti ini :

Uncompress terlebih dahulu paket  .tar.gz disini paket ada di /temp :

# tar zxvf /tmp/sendEmail-v1.55.tar.gz

# cd /tmp/sendEmail-v1.55

Copy sendEmail script ke /usr/local/bin :

# cp /tmp/sendEmail-v1.55/sendEmail  /usr/local/bin

Buat file executable :

# chmod +x /usr/local/bin/sendEmail

Contoh menggunakan sendEmail seperti ini (disini saya menggunakan smtp gmail) :

# sendEmail -f my.account@gmail.com -t myself@domain.tld -u this is the test title -m “this is a test message” -s smtp.gmail.com -o tls=yes -xu usernameonly -xp mypasswd -a /home/brokenz/perdana.txt

keterangan option:

  • -f : berarti from alias sender
  • -t : berarti to email address (tambahkan -cc dan -bcc jika anda membutuhkan)
  • -u : berarti subject dari email
  • -m : berarti message alias pesan anda
  • -s : berarti server (secara default menggunakan port 25 jika tidak bisa gunakan port 587 ex: smtp.gmail.com:587)
  • -o : berarti option lain seperti tls dan misc seperti -xu dan -xp
  • -xu : berarti username email anda
  • -xp : berarti password email anda
  • -a : berarti file attachment yang akan dikirim

Mengirim ke banyak orang

sendEmail -f myaddress@isp.net -t “admin <admin@isp.net>” user1@isp.net user2@isp.net -s relay.isp.net -u “Test email” -m “Hallo apakabar hari ini ?.”

Mengirim ke banyak orang dengan cc dan bcc

sendEmail -f myaddress@isp.net -t admin@isp.net;user1@isp.net;user2@isp.net -cc user2@isp.net tom@isp.net jess@isp.net -bcc ra@isp.net dub@isp.net kay@isp.net -s relay.isp.net -u “Test email with cc and bcc recipients” -m “Hi his is a test email.”

Mengirim email dengan isi file sebagai body dari message

cat /tmp/file.txt | sendEmail -f myaddress@isp.net -t admin@isp.net -s relay.isp.net -u “Test email with contents of file”

Mengirim email dengan isi file sebagai body dari message (cara ke 2)

sendEmail -f myaddress@isp.net -t admin@isp.net -s relay.isp.net -o message-file=/tmp/file.txt -u “Test email with contents of file”

Mengirim html email: (make sure your html file has <html> at the beginning)

cat /tmp/file.html | sendEmail -f myaddress@isp.net -t admin@isp.net -s relay.isp.net -u “Test email with html content”

Mengirim Short Message Service (SMS)/text message ke cellular phone

Untuk cara yang satu ini saya masih bingung dengan gateway sms no matrix yang saya gunakan,

./sendEmail -f usernameonly@gmail.com -t 08151700100@indosat.com -m This is an SMS message from Linux.-o tls=auto -s smtp.gmail.com -xu usernameonly -xp mypasswd

Cara Backup Data

leave a comment »

Sebagai seorang admin pasti setiap hari kita tak lepas dengan yang namanya data server, sebagai seorang admin pastinya kita juga harus mengantisipasi terjadinya hal-hal yang tidak diinginkan terhadap data kita yang ada di server. Lalu bagaimana caranya kita mengantisipasi itu, salah satunya adalah dengan mem-backup data kita secara periodic baik itu ke server lain maupun di storage khusus untuk backup. Nah, cara backup data salah satunya juga bisa dengan menggunakan bash scripting, karena secara default linux/unix sudah mendukung hal tersebut. Berikut contoh script bash untuk membackup data :

#!/bin/bash
#change direktori to source direktori
cd /home/Dokumen/
#
source_direktori=”/home/Dokumen/”
#
#struktur direktori destination = /media/backup/2010/07
#
destination_direktori=”/media/backup/$(date +%Y)/$(date +%m)/”
#
#untuk menghasilkan file kompresi dengan hasil filenya “backupdata_20100701.tar.gz “
file_tar=”backupdata_$(date +%Y%m%d).tar.gz”
#
# mencari destination direktori
# bila tidak ditemukan direktori tujuan maka kita buat script
if [ ! -d "$destination_direktori" ] ; then
echo “* Make Destination Direktori”
mkdir -p $destination_direktori
fi
#
#mencari file ods, xls, odt, dan doc (spreadsheet dan word processor) dan
#mencari file modifikasi H-1 dan H lalu copy ke directory $destination_direktori.

find $source_direktori -type f \( -iname ‘*.ods’ -iname ‘*.xls’ -o -iname \

‘*.odt’ -o -iname ‘*.doc’ \) -mtime -1 -exec cp -b –parents ‘{}’ $destination_direktori \;

#
#kompres dan hapus file aslinya
tar zcvf $destination_direktori$file_tar $destination_direktori –remove-files –exclude=’*.tar.gz’

Nah setelah script selesai dibuat sesuai keinginan kita tinggal di taruh saja di crontab untuk dijalankan scriptnya secara periodic. Semoga bermanfaat :)

Script TCP port and PID on Solaris

leave a comment »

Untuk menemukan PID dari port yang kita inginkan bisa dengan menggunakan script porting. Copy dan simpan dalam extension “.sh”. Letakkan di folder /usr/sbin/ dan /usr/bin agar menjadi absolut path jika anda belum paham apa itu absolut path dan relative path silahkan tanya sama si mbah google karena saya tidak akan menjelaskannya disini :D :

bash-3.00# cp porting.sh /usr/sbin/

bash-3.00# cp porting.sh /usr/bin/

Ubah permision script porting.sh dengan chmod a+x atau agar lebih secure gunakan option u+x agar super user saja yang bisa menggunakan script ini.

bash-3.00# chmod a+x /usr/bin/porting.sh

bash-3.00# chmod a+x /usr/sbin/porting.sh

Oya rename saja script porting.sh menjadi porting agar lebih enak di pandang :)

bash-3.00# mv /usr/bin/porting.sh /usr/bin/porting

bash-3.00# mv /usr/sbin/porting.sh /usr/sbin/porting

Sekarang bagaimana command agar kita bisa menggunakan script ini, yang pertama dengan port yang kita inginkan misal port 22 :

bash-3.00# porting -p 22
PID     Process Name and Port
_________________________________________________________
461     /usr/lib/ssh/sshd       22
sockname: AF_INET6 ::  port: 22
_________________________________________________________
16055   /usr/lib/ssh/sshd       22
sockname: AF_INET6 ::ffff:124.195.15.220  port: 22
_________________________________________________________
16056   /usr/lib/ssh/sshd       22
sockname: AF_INET6 ::ffff:124.195.15.220  port: 22
_________________________________________________________
4558    /usr/lib/ssh/sshd       22
sockname: AF_INET6 ::ffff:124.195.15.220  port: 22
_________________________________________________________
4559    /usr/lib/ssh/sshd       22
sockname: AF_INET6 ::ffff:124.195.15.220  port: 22

Nah kalau untuk list semua ya tinggal seperti ini :

bash-3.00# porting -a
PID     Process Name and Port
_________________________________________________________
287     /usr/lib/nfs/statd
sockname: AF_INET 0.0.0.0  port: 0
_________________________________________________________
324     /usr/lib/inet/inetd
sockname: AF_INET6 ::  port: 7100
sockname: AF_INET6 ::  port: 513
sockname: AF_INET6 ::  port: 23
sockname: AF_INET6 ::  port: 21
sockname: AF_INET6 ::  port: 79
sockname: AF_INET 0.0.0.0  port: 514
sockname: AF_INET6 ::  port: 514
sockname: AF_INET 0.0.0.0  port: 6112
sockname: AF_INET6 ::  port: 6481
sockname: AF_INET 0.0.0.0  port: 6481
_________________________________________________________
369     /usr/sadm/lib/smc/bin/smcboot
sockname: AF_INET 127.0.0.1  port: 5987
sockname: AF_INET 127.0.0.1  port: 898
sockname: AF_INET 127.0.0.1  port: 5988

Berikutnya edit konfigurasi pkgutil.conf

bash-3.00# vi /etc/opt/csw/pkgutil.conf

# Configuration file for pkgutil

# $Id: pkgutil.conf 7 2009-03-07 18:48:54Z bonivart $

# Master configuration file is placed in /opt/csw/etc. Place a pkgutil.conf
# file in /etc/opt/csw if you want a local override setting-by-setting

# Nothing below is mandatory to change, pkgutil will use the default values
# noted below for each option unless something is uncommented

# Mirror to use for downloads
# See http://www.blastwave.org/mirrors.php for alternative mirrors
# Default: http://blastwave.network.com/csw/unstable
#mirror=http://blastwave.network.com/csw/unstable

# Solaris 10: If you wish to limit pkgutil to installing packages
# only to the global zone, then uncomment this line. Note that pkgrm does not
# have the same option
# WARNING: do not modify this unless you know what you’re doing
# Default: blank
#pkgaddopts=-G

# Flags for use with wget, e.g. “-nv” for less verbose or “-q” for quiet
# WARNING: do not modify this unless you know what you’re doing
# Default: blank
#wgetopts=-q

# To enable use of gpg or md5, uncomment these
# NOTE: it doesn’t make sense to use md5 but not gpg so your options should be:
#       1. both disabled, 2. gpg enabled, 3. both enabled
# Default: false, false
use_gpg=true
use_md5=true

Langkah terakhir adalah sinkronisasi catalog server blastwave

bash-3.00# /opt/csw/bin/pkgutil –catalog
Fetching new catalog http://blastwave.network.com/csw/unstable/sparc/5.10 if available…
–13:30:57–  http://blastwave.network.com/csw/unstable/sparc/5.10/catalog

Checking catalog integrity with gpg.
gpg: Signature made Thu Dec 31 06:19:20 2009 WIT using DSA key ID A1999E90
gpg: checking the trustdb
gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model

gpg: next trustdb check due at 2011-08-17
gpg: Good signature from “Blastwave Software (Blastwave.org Inc.) <software@blastwave.org>”

Step 4,

Buka browser untuk mengetahui software apa saja yang sudah tersedia di blastwave di http://www.blastwave.org

dibagian software anda bisa lihat misal saya akan menginstall bittorrent, dicatalog terlihat nama software adalah CSWbittorrent. Maka langsung saja kita install dengan perintah

bash-3.00# pkg-get -i CSWbittorrent
No existing install of CSWbittorrent found. Installing…
