slow internet in lubuntu / ubuntu 12.04

this problem I got cause compalaining from my mom as internet cafe keeper :D

so the problem is "why connection so slow right now" but check on internet provider and some client that use old version that running well. only some client which use lubuntu 12.04 having slow connection.

as usual check on google that problem is because activated ip version 6 and may that machine look at the address and host to applied v.6 version.

resolve problem is only disable  ipv.6 in sysctl /etc/sysctl.conf  . with option add it on.

 

# disable IPv6
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1

or easily execute this command on terminal :

echo -e "\n# disable IPv6\nnet.ipv6.conf.all.disable_ipv6=1\nnet.ipv6.conf.default.disable_ipv6=1\nnet.ipv6.conf.lo.disable_ipv6=1" | sudo tee -a /etc/sysctl.conf

then do :

sudo sysctl -p
sudo ifconfig eth0 down
sudo ifconfig eth0 up

error short tag pada program php di centos 6

 

pengalaman ini ketika saya mendapat ke anehan ketika menjalakan aplikasi di server centos yang berupa sytax error. dan pada komputer lokal kode program ini berjalan normal, yang mana komputer lokal yang saya gunakan adalah Lubunutu.

 

jadi si centos ini hanya mengenal tag php <?php tetapi tidak mengenal tag <? , jika menuliskan kode php dengan awalan <? maka terjadilah sytax error, dan sebagai informasi framework php yang di gunakan adalah yii framework.

dan tampilan error adalah seperti ini. :

Parse error: syntax error, unexpected $end in /var/www/html/apps/protected/views/as/index.php on line 231 Call Stack:

jadi bagai mana memperbaikinya. mudah ;)

buka konfigurasi di  php.ini

vim /etc/php.ini

cari tulisan short_open_tag  pada server saya pada baris 229 dan ubah menjadi On.

 

From capture from computer

demikian mudah kan :D

and error showing like this :

Parse error: syntax error, unexpected $end in /var/www/html/apps/protected/views/as/index.php on line 231 Call Stack:

rsync dari sever dengan ssh

sedikit tips dan trik dari saya.

 

bagai mana rsync ke server melalui ssh, baik lah tanpa basa basi ini caranya.

rsync -avhP -e "ssh -p port_number" root@ipaddress_or_host:/source/location_file /Destination/on_your_computer

yang perlu di tekankan dalah -e untuk memilih mode protokol yang di gunakan dan -p port number yang digunakan karena ssh server saya tidak mengunakan port 22.

rsync from sever through ssh

well this little bit tips and tricky, handy for me may for another people. ;)

this case I used because, in my computer have bad connection directly to server but so good on local intranet, honestly it little bit nasty because it was use for download torrent then sync complete download to my computer. LOL

okay go head. this command I run on my computer which is use Lubuntu.

rsync -avhP -e "ssh -p port_number" root@ipaddress or host:/source/location_file /Destination/on_your_computer

 

most important things is -e which use to choice protocol to ssh and use option -p because that my ssh server port doesn't use port number 22.
