Catatan perjalanan Haji dari Jepang (PENDAHULUAN)

Bismillahirrahmanirrahim

Dengan menyebut nama Allah yang Maha Pengasih lagi Maha Penyayang.

Assalamualaikum warrahmatullah akhifillah dan ukhtifillah yang diberkahi Allah, aamiin..

Alhamdulillah, segala puji serta syukur selalu kita panjatkan selalu kepada Allah, Tuhan semesta alam yang memberikan kita banyak kenikmatan, dan salam shalawat kepada imam kita Rasulullah sallallahu alaihi wasallam beserta keluarga san sahabat Beliau.

Sungguh tak bisa dilupakan ketika kami diberikan kesempatan Allah untuk datang ke rumahNya pada hari itu. Bangunan berbentuk persegi, diselubungi kain hitam bertuliskan lafadz Syahadat, di salah satu sudutnya terdapat Hajar Aswad, dan pintunya bernama Mulatazam, bangunan itu tiada lain adalah Ka`bah . Bangunan yang selama ini kita sholat menghadapnya.

Hampir setahun yang lalu kami melakukan Thawaf mengelilingi Ka`bah tapi rasanya masih kemarin kami melakukannya, dan rasanya ingin sekali kami kembali lagi ke sana ( ngarep rezeki Allah ^O^)

Insya Allah akhifillah dan ukhtifillah diberikan kesempatan serupa untuk bisa pergi ke Tanah suci secepatnya ^o^// dan bagi yang sudah pergi semoga bisa ke sana lagi dalam ibadah umrah ( jangan lupa ajak ajak ^0^ )

Cuap cuap pendahuluan sampai sini aja deh hehehe,,

Sampai bertemu di postingan selanjutnya ^^

Afwan lahir batin, jazakillah khoiran katsiran

Wassalamualaikum Warrahmatullah

Linux bash profile

Understanding the Login Shell Process

When you log in to the Linux system, the bash shell starts as a login shell. The login shell typically looks for five different startup files to process commands from:

1. /etc/profile
→The /etc/profile file is the main default startup file for the bash shell. Whenever you log in to the Linux system, bash executes the commands in the /etc/profile startup first.

2. $HOME/.bash_profile

3. $HOME/.bashrc
→The .bashrc file does two things. First, it checks for a common bashrc file in the /etc directory. Second, it provides a place for the user to enter personal command aliases

4. $HOME/.bash_login

5. $HOME/.profile

/bin/bash^M: bad interpreter: No such file or directory

Sometime when working with shell script, we need to edit the shell script on Windows environment. Then when we execute the shell script on Linux environment, we will find the below error:

/bin/bash^M: bad interpreter: No such file or directory
/bin/bash^M: bad interpreter: そのようなファイルやディレクトリはありません

Since the new line code had been saved in the \ r \ n, there is a need to fix in the Linux \ n. This is because the new line code had been saved in the \ r \ n on Windows environment. In order to fix the problem, we need to convert the \r\n to \n on Linux environment. To do this, we may use the below command:

$ sed -i 's/\r//' [shell script fileName]

Below, verification

By using the command cat -e, we can see that there is additional \ r at the newline code.

$ cat -e hello.sh
#!/bin/bash^M$
echo "hello,world"^M$
This remains to run an error
$ ./hello.sh
-bash: ./hello.sh: /bin/bash^M: bad interpreter: No such file or directory
Convert line feed code by using sed command
$ sed -i 's/\r//' hello.sh
once again check with cat -e
$ cat -e hello.sh
#!/bin/bash$
echo "hello,world"$
Then, you are done!
$ ./hello.sh
hello,world

AIX command CheatSheet

★AIX compression with TAR, COMPRESS, GZIP, ZCAT
tar
tar in AIX by default does not support compression. You will need to incorporate with gzip command to have it

tar and compress at the same time.

$ tar cvf test.tar test                             # pure tar only
$ tar cvf - test | gzip > test.tar.gz        # tar and compress together

gzip / gunzip

$ gunzip -c test.tar.gz | tar tvf -           # list compress files
$ gunzip -c test.tar.gz | tar xvf -           # decompress files

★nmon command

nmon -fT -s DATAinterval(unit in seconds) -c NUMBERofExecutions

nmon -fT -s 1 -c 10800

→ Data will be recorded every 1 seconds
→ nmon data will be recorded : 1sec x 10800times = 3hours

★tcpdump

#Write an output file of tcpdump result

tcpdump -i en20 -w dumpfilename.out
tcpdump -w dumpfile

#Read the result of tcpdump

tcpdump -r dumpfilename.out
or
tcpdump -r dumpfilename.out > dumpfilename.out.result
more dumpfilename.out.result

★Check AIX Network Status
Network Interface

OVERVIEW and PROCEDURE

The task that is described in this procedure is performed in the AIX terminal window. If the terminal window

is not open at this time, you may do so by using the instructions in Hardware Management Console Overview.

After the terminal window is open, simply type

netstat -r

Where netstat = network status

-r = route

The primary information to check is located in the first entry in the top-left, “default”, and then the column

to the far right titled “If”. This column tells you what interface is being used.  For instance, “en0”.

Secondarily, you may run an additional command to

entstat -dt en0

Where entstat = network settings

-dt = display all statistics

en0 = The interface from the If column

As a result of this command, the  information that you should check is as follows:

Link Status : up  Tells you that the cable is attached and is connected to a switch. In other words, the cable

from the system to the network is functional. This is a good thing!

NOTE: If the status is down (Link Status : down), there is a problem with the cable, or the switch, or the

port.

Media Speed Selected  Should read “100 Mbps Full duplex”

Exception: If the machine has a gigabit card, it will read “Autonegotiate”

Media Speed Running   Should read “100 Mbps Full duplex”

IF your system has a NIC / NIB (network interface backup) as en20, you may try the below command to check the

status of each primary and secondary network condition.

entstat -dt en20 | egrep “(Link Status|Media Speed)”

command result (sample):
Link Status: Up
Media Speed Selected : Autonegotiation
Media Speed Running : 1000 Mbps Full Duplex
Link Status: Up
Media Speed Selected : Autonegotiation
Media Speed Running : 1000 Mbps Full Duplex

Cara Akses ke Balai Indonesia (Sekolah Republik Indonesia Tokyo – SRIT)

Warga negara Indonesia yang berdomisili di daerah Kanto (Tokyo, Saitama, Chiba, Kanagawa dan sekitarnya) terkadang sering mengadakan kegiatan besar di Balai Indonesia SRIT. Bagi yang belum mengetahui lokasi SRIT, mungkin akan sedikit kesulitan menemukan lokasinya yang boleh dibilang cukup jauh dari stasiun kereta terdekat, Stasiun Meguro (JR Yamanote Line, Tokyo Metro Namboku Line, Toei Mita Line, Tokyu Meguro Line).

Nah, berikut ini akan coba dijelaskan mengenai cara akses yang ditempuh untuk menuju Balai Indonesia SRIT. Dari Stasiun Meguro Anda dapat menggunakan bus. Naiklah bus dengan nomor-nomor yang tertera di bawah ini dari perhentian bus West Exit Stasiun JR Meguro. Turunlah di perhentian bus Motokeibajomae (元競馬場前).

  • 黒01 jurusan O-okayama Shogakkoumae (大岡山小学校前行き)
  • 東98 jurusan Todoroki Sosyajo (等々力操車所行き)
  • 黒02 jurusan Futako Tamagawa Eki (二子玉川駅行き)
  • 黒02 jurusan Sangenjaya Eki (三軒茶屋駅行き)

Setelah turun di perhentian bus Motokeibajomae, seberangilah jalan besar (Meguro Dori) pada zebra crossterdekat kemudian belok ke kanan. Pada belokan ketiga beloklah ke kiri dan berjalan lurus sampai ke ujung gang kemudian beloklah ke kiri. Anda akan dapat melihat gerbang Balai Indonesia (SRIT) di ujung gang tersebut.

Anda dapat juga berjalan kaki dari Stasiun Meguro ke Balai Indonesia (SRIT). Perjalanan kaki membutuhkan waktu sekitar 17 menit (lihat peta di bawah).
