Codeigniter + Nginx + FastCGI

Just another quick post :
- Ubah setting $config['uri_protocol'] ke REQUEST_URI
- Edit file nginx.conf untuk virtual host yg pakai CI. Rewrite rule :

if (!-e $request_filename) {
rewrite ^(.*) /index.php?$1 last;
}

- Restart nginx

Membersihkan File dari Iframe Injection

Cara nyari file yang kena injeksi iframe :

grep ... * | grep iframe

Cara hapusnya :

find . -name '*.*' | xargs perl -pi -e 's/^.*\<iframe src.*chura\.pl.*$/ /g'

Dari contoh diatas, iframe src yang ketemu mengarah ke chura.pl . Makanya pada perintah kedua, input chura.pl dimasukkan supaya kode iframe langsung dihapus dan ngga berpengaruh ke iframe lainnya di file yang sama (kalau memang ada).

Find core dump Files In Home Dir

Here’s small script to find any core dump files generated in /home directory :

#!/bin/bash
for((i=0;i> searchcoredump.txt

Use searchcoredump.txt to analyze every core dump file you’ve found. Or you can delete it one by one. :D 

[root@pengki ~]# for hapus in `cat /root/searchcoredump.txt`; do rm -rf $hapus; done

Finding core dump files will take a loooong time if your home directory is big (in size, and node). You can use screen command to let the machine works for you so you can do another thing (or have a nice sleep :P ).

Pinger

for namahost in `cat domain.txt`
  do
    ping $namahost -c 1
done

Ini kasus ketika saya terlalu malas untuk mengeksekusi perintah ping berkali-kali ke banyak host. Jadi sekalian iseng nulis bash script-nya. Daftar nama host (eh boleh IP juga kok) disimpan di satu file (domain.txt).

Tinggal dieksekusi..

./pinger > hasilping.txt

Lalu hasilnya dibaca. :) )

more hasilping.txt
