Cara konfigurasi sosreport

Apa sih sosreport itu?
Biasanya sosreport itu digunakan untuk mengumpulkan informasi dan konfigurasi dari server.
Command sosreport sendiri merupakan pakcage dari sysstat.
Secara default, sosreport hanya menyimpan 7 hari log.
Agar tercantum 1 bulan yaitu 30hari, maka kita perlu mengedit konfigurasi dari sysstat di /etc/sysconfig/sysstat
#vi /etc/sysconfig/sysstat

# How long to keep log files (in days).
# If value is greater than 28, then log files are kept in
# multiple directories, one for each month.
HISTORY=30

Selamat mencoba :kiss

Install Skype di Igos Nusantara 8 64bit

Pengen skypan tapi belum di install di IGN 8 :(
Kemudian saya coba install...tapi keluar error!
laptop 64 bit tapi dependensinya 32 -_- jadi terjadi konflik ketika akan install. Seperti ini:

Dari group facebook Igos Nusantara, ternyata ada cara lain supaya skype dapat terinstall.
1. download dahulu paketnya dari repo.
#mkdir /root/skype#cd /root/skype#yumdownloader --resolve skype
2. Install paket2 tersebut:
#rpm -ivh --force --nodeps *.rpm

Ternyata bisa ^o^
yup sekarang bisa pakai skype deh ;)

Wifi fedora 17 tidak terdetek di lenovo edge

Sebulan yang lalu saya menginstall fedora 17 di lenovo edge 330.
Ternyata wifinya tidak terdetek!
waduh kenapa ya...?
setelah googling di yahoo eh google :D ternyata itu bugs dari fedoranya.
Harus ada firmware yang diinstall.
$su -
#yum install iwl2030-firmware 
 Kemudian reboot laptopnya ^o^
dan nikmati wifinya ^o^

Install Java Plugins on Firefox

Ketika mau masuk aplikasi di browser yang membutuhkan java plugins, ternyata ga bisa!Firefox minta install plugins java dulu. Kemudian saya coba search java plugins, tapi ternyata tidak ada.
Saya install java-jdk, namu tetap tidak bisa.
Hal yang harus dilakukan selanjutnya adalah memastika java sudah terinstall atau belum.

#java -version

java version "1.7.0_09-icedtea"
OpenJDK Runtime Environment (fedora-2.3.3.fc17.1-x86_64)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)

Ternyata java saya sudah terinstall. Tapi kenapa ketika saya coba browser, masih diminta untuk install java plugins :confused. Saya mencoba ketik about:plugins di firefox dan ternyata tidak ditemukan java plugins.

Well, langkah selanjutnya yang harus dijalankan adalah membuat symbolic link libnpjp2.so dari java ke plugins directory pada mozilla firefox agar plugins dikenali dan aktif.
Dalam kasus ini java saya ada di /usr/java/jre1.7.0_09/lib/amd64/ dan mozilla firefox ada di /usr/lib64/mozilla/plugins

#cd /usr/lib64/mozilla/plugins
#ln -s /usr/java/jre1.7.0_09/lib/amd64/libnpjp2.so
#la -la

Restart Firefox, kemudian cek about:plugins untuk memastikan apakah java sudah aktif atau belum. Jika sudah maka akan muncul seperti ini:



Have a nice trying ^o^
Desktop yang saya pakar Igos Nusantara 8.0 ^o^

Cara Akses Windows Share/Samba Share di nautilus

Ketika ingin mengakses samba share atau windows share di nautilus, saya gagal mengakses, seperti error dibawah ini: "Unable to mount location"



Selain itu ada 1 lagi error yang biasa terjadi, tapi sayang saya lupa screenshot :Peace:
Solusi dari error tersebut adalah dengan menginstall package gvfs-smb. Untuk gnome dekstop, ada 2 package gvfs-smb dan gnome-vfs.
Install untuk IgosNusantara/fedora/centos/rhel:

#yum install gvfs-smb

Kemudian coba buka nautilus -> ctrl+L dan ketik smb://ipserver atau smb://servername.

note: Jika masih belum berhasil, bisa coba install package samba-client.
#yum install samba-client

That's all :D
*Desktop yang saya pakai Igos Nusantara 8.0 / IGN8 ^o^

Cara Install Squirrelmail di RHEL/Centos

Kemarin bingung cara install squirrelmail di RHEL 6 @.@
klo ambil dari repo EPEL, minta dependency php terus...jadi pusing @.@
cekidot cara install Squirrel mail:

  1. Pastikan webserver (httpd package) dan dovecot sudah terinstall dan running.
  2. Download squirrelmail, bisa di download disini: download squirrelmail
  3.  extract downloadan tersebut. Letakkan hasil extract di /usr/share                                                           #tar -xzvf squirrelmail-webmail-1.4.22.tar.gz
  4. Buat alias pada /etc/httpd/conf.d/squirrelmail.conf yang berfungsi untuk mendefinisakan ketika akan dibuka di browser. File konfigurasi squirrelmail.conf dibuat secara manual.                                             #cat /etc/httpd/conf.d/squirrelmail.conf                                                                                               Alias  /mail    /usr/share/squirrelmail                                                                                                       Alias  /mail    /usr/share/squirrelmail
  5. Jalankan script conf.pl didalam /usr/share/squirrelmail/config                                                             #cd /usr/share/squirrelmail/config                                                                                                              #./conf.pl                                                                                                                                           Pilih "Set pre-defined settings for specific IMAP servers", kemudian pilih Courier. Hal tersebut untuk menset confignya.
  6. restart service httpd.                                                                                                                                    #service httpd restart                                                                                                                          
  7. Login menggunakan user local dalam kompter.
  8. Apa masih error?:D
  9. Jika ada tulisan error yang berhubungan dengan IMAP, yang harus dilakukna adalah konfigurasi dovecot.
  10. Pada konfigurasi /etc/dovecot/dovecot.conf, beri tambahan/edit variable protocols = imap imaps pop3 pop3s
  11. Kemudian edit /etc/dovecot/conf.d/10-mail.conf,edit variable mail_location menjadi mail_location = maildir:~/Maildir.
  12. Edit /etc/dovecot/conf.d/20-pop3.conf, edit variabel pop3_uidl_format menjadi pop3_uidl_format = %08Xu%08Xv.
  13.  Restart service dovecote                                                                                                                   #service dovecot restart
Yak bgitulah kira2 caranya :D
Cara di atas dengan menonaktifkan firewall dan mendisable/permissive selinux.
