# This example is available on Github at https://github.com/chip/invoicethat-admin

# For simplicity's sake, I put this into app.rb

# Root directory of my Rails app
    RAILS_ROOT = '/Users/deploy/Sites/rails_invoice'

    # Setup load_paths for ActiveSupport
    require 'active_support'
    relative_load_paths = %w(app/models)
    ::ActiveSupport::Dependencies.load_paths = relative_load_paths.map { |path|
      File.expand_path(path, RAILS_ROOT)
    }
    
    # Connect to the Rails app database
    require 'active_record'

sudo postsuper -d ALL


I guess it always helps to READ the man pages. ;)

Platform issues might be relevant for some admins, so let's find out how the server is configured to run Postfix...

sudo postconf -d | grep ^mail_version
mail_version = 2.3.8
cat /etc/issue
Debian GNU/Linux 4.0

Now that I have those particulars, I need to query the aliases database. But, how do you find that out? Let's look further...

sudo postconf -n | grep ^alias
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases

Perfect. Let's move on to finding who receives root mail.

postmap -q root hash:/etc/aliases

Wha??? No results? That an easy enough fix. Just fire up your favorite editor for /etc/aliases to add an entry for root.

root: you@domain.com
mailer-daemon: postmaster
postmaster: root

Of course, don't forget that you@domain.com should be changed to suit your needs.

But, we're not done! At this point, Postfix is not aware of our new alias settings, as it reads /etc/aliases.db, not /etc/aliases, so let's fix this.

Some of the documentation I came across referred to using postmap to rebuild aliases.db, but I found that I ran into the 'record is in "key: value" format; is this an alias file?' warning. Well, I probably wasn't doing something right, so instead I tried an alternative:

sudo newaliases
sudo postfix reload

I then check my work...

sudo postmap -q root /etc/aliases

This time, I got the expected results: you@domain.com. Nice. So I watched the mail logs as I sent a test mail message:

sudo tail -f /var/log/mail.log

For me, it worked. Yay!

If your message could not be delivered, make sure you read the mail logs carefully for specific errors. Your server configuration might need to be tuned depending on your needs and the error generated, but that's for another post.

Cheers.

Here's what I did to import that into a git repo:

git svn clone -t '' -b '' -T '' svn+ssh://host.tld/path/to/repo/

In the process of finding the magic flag for importing, I found http://jo.irisson.free.fr/?p=64 to be particularly descriptive and helpful in my understanding of the import process. However, git-svnimport has been deprecated, so I used git-svn instead.

I had never used this before, but running it as follows showed me a lot of useful information about the ports on my system:

sudo port outdated

sudo port selfupdate
sudo port install db44 +darwin_8
sudo port outdated
sudo port upgrade apr bzip2 gcc_select libevent libpcap \
libxml2 memcached pcre
sudo port upgrade apache2

I found http://www.nabble.com/Issue-installing-Apache-2-on-Leopard-td16426260.html to be especially helpful during the process, but mainly was happy to discover the "outdated" command. I hope you find this useful, too.

Since I found that each git-core dependency failed due to fetch errors, I decided to override that behavior, as described at http://guide.macports.org/#development.examples.eliminate.

Basically, it is a simple 3 step process to follow:

1. Attempt to install the port
2. Manually download the source file that could not be fetched
3. Edit the Portfile and start the process again
   

Here's exactly how I did it...

1. Attempt to install the port

Here I am attempting to install the git-core port, but it fails on rsync:

chip-castles-powerbook-g4-17:/opt/local/var/macports/sources/rsync.macports.org/release/ports/devel/popt deploy$ sudo port install git-core
Portfile changed since last build; discarding previous state.
---> Fetching rsync
---> Attempting to fetch rsync-3.0.4.tar.gz from http://rsync.samba.org/ftp/rsync/
---> Attempting to fetch rsync-3.0.4.tar.gz from http://rsync.samba.org/ftp/rsync/src/
---> Attempting to fetch rsync-3.0.4.tar.gz from http://svn.macports.org/repository/macports/distfiles/rsync
---> Attempting to fetch rsync-3.0.4.tar.gz from http://svn.macports.org/repository/macports/distfiles/general/
---> Attempting to fetch rsync-3.0.4.tar.gz from http://svn.macports.org/repository/macports/downloads/rsync
Error: Target org.macports.fetch returned: fetch failed
Error: The following dependencies failed to build: rsync
Error: Status 1 encountered during processing.

2. Manually download the source file that could not be fetched

Based on the errors above, I pointed my web browser to http://rsync.samba.org/ftp/rsync/ and downloaded rsync-3.0.4.tar.gz.

Since it downloaded to ~/Desktop, I had to copy it to the appropriate location, which in my case was under:

/opt/local/var/macports/distfiles/

sudo cp ~/Desktop/rsync-3.0.4.tar.gz /opt/local/var/macports/distfiles/rsync/

As a precautionary measure, it is best to run md5 against the downloaded file to be sure that it matches the checksum listed in the Portfile.

3. Edit the Portfile and start the process again

Now I need to find the Portfile. It varies for each dependency, but on my laptop I always use this as a base directory:

/opt/local/var/macports/sources/rsync.macports.org/release/ports/

chip-castles-powerbook-g4-17:/opt/local/var/macports/sources/rsync.macports.org/release/ports deploy$ find . -name "rsync*"

./net/rsync
./net/rsync/files/rsyncd.conf.example
./net/rsync-devel
./net/rsync-lart

Here's my rsync Portfile:

startupitem.pidfile auto ${prefix}/var/run/rsyncd.pid
}

==================================

Basically, I repeat this process for each fetch failure. For git-core, there were a good number of them. Off the top of my head: curl, expat, gettext, ncurses, openssh, perl5.10, perl5.8, pkgconfig, popt.

There were probably others, but I think you get the idea.

/Library/Ruby/Site/1.8/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- capistrano/ext/multistage (LoadError)

I did this to fix:

sudo gem install capistrano-ext

OK. I have to admit, I'm just getting started. But I did run into some issues installing it on Ubuntu 7.10 and wanted to share how I fixed them.

So, I tried installing per the website tutorial, like so:

sudo gem install webby

However, it complained since I didn't have the correct version of hpricot:

ERROR: Error installing webby:
webby requires hpricot (= 0.6.0, runtime)

No worries. Just do this prior to installing webby:

sudo gem install hpricot --version=0.6.0

Remember, the --version option is the key!

By default, installing ruby alone doesn't give you the necessary library bindings that you might need later. I solved this like so:

sudo apt-get install ruby1.8-dev libyaml-ruby libzlib-ruby

During this process, I also noticed another command that might ease this process in the future, although I don't have a clean slate to work with, but it's worth noting nonetheless:

sudo apt-get install ruby-full

rubygems issues:

Sometimes rubygems has issues with stalling, at least in my experience, so one way of dealing with that is to issue this to clear out the cache:

sudo gem update -V

And then update the system in verbose mode:

sudo gem update --system -V

I also found that I needed to edit /usr/bin/gem as follows:

require 'rubygems'
require 'rubygems/gem_runner'

cd ~/sandbox
svn checkout file://path/to/repo tmpwc
cd tmpwc
svn mkdir trunk
for f in *; do svn mv $f trunk; done
svn mkdir branches tags
svn commit -m "Finally got organized!"

This solution was found as part of a larger thread of correspondence, found here:

Oh well. No worries, I thought. I'll just ssh into my imac at home and run the svn commit from there. But wait - my imac was in sleep mode and simply wouldn't allow me to connect. I thought, now what?

Well, a quick googling revealed this very important post:
http://www.macosxhints.com/article.php?story=20020220095929695

Although there were Python and Perl solutions presented, I decided to implement the example provided in PHP since it required no special libraries to run. Here's the code (Special THANKS to karnat10 for posting this one!):

###########################################

function wakeonlan($ip,$mac) {

$socket = fsockopen("udp://".$ip,9,$errno);

if (!$errno) {
$magicpacket = str_repeat(chr(0xff),6).str_repeat(pack("H*",$mac),16);
fputs($socket,$magicpacket);
fclose($socket);
}
}

// Call the function like this:

wakeonlan("12.34.56.78","a0b1c2d3f456");

###########################################

Now, all I had to do was fill in my IP address where there was "12.34.56.78" and my imac's MAC address where there was "a0b1c2d3f456".

Once that was done, I named this script wake_up_imac.php and placed it in ~/bin on my office mac mini.

After running the command "php ~/bin/wake_up_imac.php", I was in - Whooot!!!

Then I setup a few aliases in ~/.bash_login to ease my login process:

alias wake_up_imac="php ~/bin/wake_up_imac.php"
alias ssh_home="wake_up_imac; ssh user@12.34.56.78"

Now to login to my imac at home, all I have to do is run "ssh_home". It doesn't matter whether the imac is in sleep mode or not since the alias takes care of the waking up prior to the ssh login.

Wow... I'm super stoked. Now I'm off to perform that commit. ;)

Also of note is that /etc/init.d/apache2 stop is broken, so I created a bash alias as follows as a workaround:
alias apstop='sudo killall -9 apache2'

Further work should be to monitor the server's memory consumption and load and tune passenger accordingly.

How to : Connect to Ubuntu NFS from Mac OSX
Connect to a Ubuntu Linux NFS server from a Mac running OSX.
This works especially well with Gigabyte ethernet.
firestarter reports a ~ 25 Mbs transfer rate.
First make sure you have all of the proper packages on the Ubuntu side (tested in Feisty Fawn):

In terminal:
sudo apt-get install nfs-kernel-server nfs-common portmap

Now open /etc/export

In terminal:
sudo vim /etc/exports

add this and save:
/home/whatEverDirectory 192.168.0.104(rw,async,all_squash,insecure,anonuid=1000,anongid=1000)

restart nfs
In terminal:
sudo /etc/init.d/nfs-kernel-server restart

On the Mac client side:

open the finder
In the menu bar: go>Connect to Server
type: nfs://IPAddressOfServer/home/whatEverDirecotry

If I ever need to connect from the Linux box to my Mac, I'll update the tutorial later.
