Indicator Systemtray Unity On Demand System Tray For Ubuntu

When this mode is used, the system tray icons arent hidden (until you middle-click it again).

You can move the icons horizontally by scrolling on the Indicator Systemtray icon on the Unity panel. Moving the icons to the left of the indicators like in the screenshot above is a bit tricky because once the icons are on top of Indicator Systemtray, you wont be able to scroll on it any more, but you can change this via dconf-editor (see below).

Update: you can now change background for both indicator modes. However, to be able to access the background settings from the indicator menu, you need to set Indicator Systemtray Unity to the floating mode (mode 1 above):

sudo apt-get install dconf-editor

Install Indicator Systemtray Unity in Ubuntu

Install MATE 1 12 1 In Ubuntu MATE 15 10 Or 16 04 Via PPA

• you you shouldnt need the Ubuntu Xenial PPA for long because as soon as the MATE 1.12 packages are accepted into Debian Unstable, they should be automatically imported into Ubuntu 16.04.
• the small MATE Dock applet I wrote about a while back was added to Debian Git recently by Martin Wimpress, and until Ubuntu and Debian reinstate the gir1.2-wnck-1.0 package (which was dropped a while back and is required by this applet), you can install this applet by using the Wily/Xenial Ubuntu MATE PPAs.

Install Proxy Squid Lusca di Linux Ubuntu Server 14 04 dengan Mikrotik

1. Topologi yang saya gunakan seperti dibawah ini.
   IP Internet : xxx.xxx.xxx.xxx
   IP Proxy : 192.168.3.2
   IP Client 1 : 10.10.8.0/22
   IP Client 2 : 192.168.4.0/24
   IP Client 3 : 192.168.5.0/24
   IP Client 4 : 192.168.6.0/24
2. Pastikan Ubuntu Server sudah bisa ping ke gateway, client, dan internet.
3. Masuk sebagai root.
   

   $ sudo su

4. Lakukan Update terlebih dahulu.
   

   # apt-get update

5.  Lakukan penginstallan Squid dan kawan-kawan.
   

   # apt-get install apache2 php5 squid squidclient squid-cgi gcc build-essential sharutils ccze libzip-dev automake1.9 libfile-readbackwards-perl -y

6. Download paket LUSCA nya.
   

   # wget https://dl.dropboxusercontent.com/s/rj083vnq9sc3aye/LUSCA_HEAD-r14809-patch.tar.bz2

   Mirror
   

   # wget http://backcode.googlecode.com/files/LUSCA_HEAD-r14809-patch.tar.bz2

7. Setelah selesai lakukan ekstrak.
   

   # tar -xvjf LUSCA_HEAD-r14809-patch.tar.bz2

8. Masuk ke tahap pengkonfigurasian. Sebelumnya kita harus tau kode CFLAG dari tipe prosessor yang akan di pasang Lusca dengan cara lihat CPU info.
   

   # cat /proc/cpuinfo

   Amati bagian yang seperti ini.
   
   processor : 1
   vendor_id : GenuineIntel
   cpu family : 6
   model : 28
   model name : Intel(R) Atom(TM) CPU D525 @1.80GHz
   
   Setelah mengetahui tipe processor cari CFLAG dari link berikut: Link1 dan Link2 khusus intel XEON tidak menutup kemungkinan bisa mencari di mesin pencari.
   maka akan mendapatkan kode CFLAG sebagai berikut:
   
   CHOST="i686-pc-linux-gnu" CFLAGS="-march=atom -O2 -fomit-frame-pointer -pipe" CXXFLAGS="${CFLAGS}"
   
   Copy kemudian simpan sementara di text editor dan ditambahkan
   
   ./configure -prefix=/usr -exec-prefix=/usr -bindir=/usr/sbin -sbindir=/usr/sbin -libexecdir=/usr/lib/squid -sysconfdir=/etc/squid -localstatedir=/var/spool/squid -datadir=/usr/share/squid --enable-gnuregex --enable-async-io=24 --with-aufs-threads=24 --with-pthreads --with-aio --with-dl --enable-storeio=aufs,null --enable-removal-policies=heap --enable-icmp --enable-delay-pools --disable-wccp --enable-snmp --enable-cache-digests --enable-default-err-language=English --enable-err-languages=English --enable-linux-netfilter --disable-ident-lookups --with-maxfd=65535 --enable-follow-x-forwarded-for --enable-large-cache-files --with-large-files --enable-referer-log
   
   Sehingga menjadi
   
   CHOST="i686-pc-linux-gnu" CFLAGS="-march=atom -O2 -fomit-frame-pointer -pipe" CXXFLAGS="${CFLAGS}" ./configure -prefix=/usr -exec-prefix=/usr -bindir=/usr/sbin -sbindir=/usr/sbin -libexecdir=/usr/lib/squid -sysconfdir=/etc/squid -localstatedir=/var/spool/squid -datadir=/usr/share/squid --enable-gnuregex --enable-async-io=24 --with-aufs-threads=24 --with-pthreads --with-aio --with-dl --enable-storeio=aufs,null --enable-removal-policies=heap --enable-icmp --enable-delay-pools --disable-wccp --enable-snmp --enable-cache-digests --enable-default-err-language=English --enable-err-languages=English --enable-linux-netfilter --disable-ident-lookups --with-maxfd=65535 --enable-follow-x-forwarded-for --enable-large-cache-files --with-large-files --enable-referer-log
9.  Pindah ke directory LUSCA dilanjut Compile LUSC
   

   # cd LUSCA_HEAD-r14809
   # make clean
   # CHOST="i686-pc-linux-gnu"CFLAGS="-march=atom -O2 -fomit-frame-pointer -pipe"CXXFLAGS="${CFLAGS}"./configure -prefix=/usr -exec-prefix=/usr -bindir=/usr/sbin -sbindir=/usr/sbin -libexecdir=/usr/lib/squid -sysconfdir=/etc/squid -localstatedir=/var/spool/squid -datadir=/usr/share/squid --enable-gnuregex --enable-async-io=24 --with-aufs-threads=24 --with-pthreads --with-aio --with-dl --enable-storeio=aufs,null --enable-removal-policies=heap --enable-icmp --enable-delay-pools --disable-wccp --enable-snmp --enable-cache-digests --enable-default-err-language=English --enable-err-languages=English --enable-linux-netfilter --disable-ident-lookups --with-maxfd=65535 --enable-follow-x-forwarded-for --enable-large-cache-files --with-large-files --enable-referer-log
   # make
   # make install

10.  Buat directory proxy untuk cache nya, dan dilanjut merubah hak akses dari directory tersebut menjadi hak akses proxy.
    

    # mkdir /proxy
    # chown -R proxy:proxy /proxy
    # chmod -R 777 /proxy

11. Buat directory penyimpanan Log cache nya, dan dilanjut merubah hak akses dari directory tersebut menjadi hak akses proxy.
    

    # mkdir /var/log/squid
    # chown -R proxy:proxy /var/log/squid

12. Download konfigurasi squid. Namun konfigurasi ini hanya HTTP saja yang bisa ter cache, untuk yang lain bisa mencari konfigurasi sendiri.
    

    # wget https://dl.dropboxusercontent.com/s/wp4qv6yh80z0b62/fileconfig.tar.gz

    Mirror
    

    # wget https://dl.dropboxusercontent.com/u/64064946/fileconfig.tar.gz

13. Ekstrak dan copykan file konfigurasi tersebut ke dalam file /etc/squid
    

    # tar -xvf fileconfig.tar.gz
    # cp fileconf/* /etc/squid

14. Beri hak akses dan eksekusi semua file berekstensi .pl
    

    # chmod 0755 /etc/squid/*.pl

15. Lakukan konfigurasi sesuai topologi.
    

    # nano /etc/squid/acl.conf

    
    cari baris  acl localnet src 192.168.1.0/24. Lalu ganti bagian 192.168.5.0/24 dan tambahkan dibawahnya IP yang dapat berhubungan dengan proxy, sebagai contoh :
    
    acl localnet src 10.10.8.0/22
    acl localnet src 192.168.4.0/24
    acl localnet src 192.168.5.0/24
    acl localnet src 192.168.6.0/24
    
    sesuai dengan topologi yang anda gunakan. Jika sudah simpan dengan menekan tombol CTRL + X dilanjut tombol Y kemudian ENTER.
16. Lakukan konfigurasi untuk merubah directory cache proxy
    

    # nano /etc/squid/squid.conf

    Cari bagian cache_dir aufs /proxy 16000 37 256 , lalu ganti bagian /proxy menjadi directory disk cache sesuai tempat cache tersimpan.
    angka 16000 (satuannya megabyte) merupakan besaran penyimpanan cache. untuk normalnya ukuran cache sebesar 80% dari total hardisk
    Angka 37 diperoleh dari rumus : ukuran 80% disk cache  dalam satuan byte/13/256/256 X 2.
    Kira-kira cara menghitungnya seperti ini : 16000000/13/256/256 X 2 = 37.5. Dibulatkan saja menjadi 37.
17. Lakukan konfigurasi untuk merubah RAM

    # nano /etc/squid/tune.conf

    Cari bagian ipcache_size 4096 lalu ganti angka 4096 dengan 2X ukuran RAM dalam satuan Megabyte. Sebagai contoh, tertulis 4096. karena hasil dari 2 X ukuran ram yaitu 2048.
    Setelah itu cari lagi bagian fqdncache_size 2048 lalu ganti angka 2048 dengan ukuran RAM dalam satuan Megabyte
18. Hentikan service Squid3 pada server agar tidak terjadi bentrok dengan squid lusca.
    

    # service squid3 stop

19. Lalu ketikkan perintah
    

    # squid -f /etc/squid/squid.conf -z

20. Jalankan Squid
    

    # squid -NDd1 &

21. Buat autorun pada squid apabila server restart bisa jalan dengan otomatis
    

    # nano /etc/init.d/squid

    Copykan script dibawah ini
    

    #! /bin/sh
    #
    # squid Startup script for the SQUID HTTP proxy-cache.

22. Berikan hak akses dan buat file autorun
    

    # chmod 755 /etc/init.d/squid
    # update-rc.d squid defaults

23. Hentikan secara autostart squid3
    

    # nano /etc/rc.local

24. Isikan
    

    service squid3 stop

25. Konfigurasi MikroTik supaya client dipaksa untuk berbelok ke Proxy Squid. Ketikkan di terminal seperti di bawah ini:
    

    ip firewall nat add action=dst-nat chain=dstnat comment=”paksa-ke-proxy” src-address=!192.168.3.2 disabled=no dst-port=80 protocol=tcp to-addresses=192.168.3.2 to-ports=3128

26. Untuk memantau hasil cache bisa mengetikkan sintax di bawah ini di mesin server.
    

    # tail -f /var/log/squid/access.log | ccze

27. Dan hasilnya adalah seperti dibawah ini.
