0 comments By jared.folkins Filed in housing, Howto, Nerd, Tutorial, Ubuntu Tagged with , , , , , , December 23rd, 2009 @

1) Make sure that you have have ssh installed on your system.

sudo apt-get install openssh-server openssh-client

2) Open the sshd_config file using VI

sudo vi /etc/ssh/sshd_config

3) Here is the file in its entirety that was created by the installation process

...

5) Change the default port that is currently 22, to a non standard port. I changed mine to 22999

# What ports, IPs and protocols we listen for

...

6) Write/Quite so that you can save the changes to the file.

7) Now, all we have to do is restart the ssh daemon and it will listen from the new port.

sudo /etc/init.d/ssh restart

8 ) Finally, from another linux (or whatever OS you prefer) box, use the SSH client and login to your newly reconfigured server. Make sure to change the port using the ‘-p’ flag.

Example: ssh YOUR_USERNAME@IP_ADDRESS_OF_SERVER -p 22999

ssh jaredfolkins@192.168.1.107 -p 22999

(Nerd) Ubuntu + Vim + ZendFramework-1.9.2 + .pthml syntax highlighting

1 comment By jared.folkins Filed in Nerd, OOP, PHP, VIM, Zend Tagged with , , , , , September 9th, 2009 @

1) From the command line ‘cd’ to your ‘home’ directory


test-box@jbuntu:~$ cd

2a) Check to see if the .vimrc file exists


test-box@jbuntu:~$ ls .vimrc

If the terminal outputs nothing, then that means the file does not exist.

2b) If you get the following


test-box@jbuntu:~$ ls .vimrc
.vimrc

It means that the file does exist and we just need to edit it.

3) If the file does not exist just ‘touch’ the file. If it DOES exist, just skip this step.


test-box@jbuntu:~$ touch .vimrc

4) From this point, ‘vi’ the ‘.vimrc’ file. You primarily need the following lines and you are more than welcome to copy/paste. Write/Quite when finished.


if has("autocmd")
autocmd BufEnter *.phtml set syn=php
endif
syn on

Now the next time you open VI it should have the desired highlighting for .phtml files found in the Zend Framework.

Below is my ‘.vimrc’ file in it’s entirety. Just for the record. It also allows for syntax highlighting to occur in CakePHP .ctp files along with some other settings that I prefer.


set tabstop=2
set shiftwidth=2
set expandtab
if has("autocmd")
autocmd BufEnter *.ctp set syn=php
autocmd BufEnter *.phtml set syn=php
endif
syn on
set ai

(Nerd) Upgrading eeePC 1005ha Firmware

5 comments By jared.folkins Filed in eeePC, Nerd, netbook Tagged with , , , , , , September 2nd, 2009 @

So I am trying to hack my eeePC in order to make it do…er…stuff. And in the process I realized my firmware was running a little behind. And do you know what happened when I tried to upgrade it? I got an error.

'1005ha.rom' Not Found

And so I took the following steps to fix it.

  1. Renamed my ROM file from 1005HA-ASUS-0703.ROM to 1005HA.ROM
  2. Formatted a thumb drive to FAT32
  3. Copied over the .ROM file into the root directory of the thumb drive
  4. Reboot
  5. Pressed F2 to get into BIOS
  6. Change the boot device priority to make the USB drive the Primary
  7. Went into boot settings and DISABLED ‘quiet boot’ (so that we could see POST info)
  8. DISABLE ‘Boot Booster’
  9. pressed the F10 key and saved my BIOS settings
  10. During POST I pressed Alt+F2

eeePC_Asus_1005ha_firmware_upgrade_picture

It found my renamed .ROM ’1005ha.rom’ and Viola! All set.
