first install mrtg via macports

===========

http://mrtg.darwinports.com/

If you haven’t already installed Darwin Ports, you can find easy instructions for doing so at themain Darwin Ports page.

Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/mrtg
%  sudo port install mrtg
Password:

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching mrtg
--->  Verifying checksum for mrtg
--->  Extracting mrtg
--->  Configuring mrtg
--->  Building mrtg with target all

--->  Staging mrtg into destroot

--->  Installing mrtg

Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using mrtg with these commands:

%  man mrtg
%  apropos mrtg
%  which mrtg
%  locate mrtg

Where to find more information:

INSTALLING ON MAC OS X Unichars

updgrade ports to latest

$ port install glib2
$ gem install unichars

How to do it

First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:

a@A:~> ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/a/.ssh/id_rsa):
Created directory ‘/home/a/.ssh’.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A
Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine):

a@A:~> ssh b@B mkdir -p .ssh
b@B’s password:
Finally append a’s new public key to b@B:.ssh/authorized_keys and enter b’s password one last time:

a@A:~> cat .ssh/id_rsa.pub | ssh b@B ‘cat >> .ssh/authorized_keys’
b@B’s password:
From now on you can log into B as b from A as a without password:

a@A:~> ssh b@B hostname
B
A note from one of our readers: Depending on your version of SSH you might also have to do the following changes:

Put the public key in .ssh/authorized_keys2
Change the permissions of .ssh to 700
Change the permissions of .ssh/authorized_keys2 to 640

Creation of additional FTP users for Plesk Linux
Posted by ankur under Linux, Plesk Control Panel
Plesk is a great Control Panel in the shared hosting environment, but there are a few things that are not available in the Control Panel. For example, you cannot create additional FTP user in Plesk Control panel for Linux (this support is enabled in Plesk for windows). But some time it is required to have multiple FTP accounts to upload/download data. You need to have shell access since the Plesk control panel won’t allow it in the GUI.

Assuming you already have an existing domain (example.com) with the primary FTP user (jack) with password (schmidt) with home directory (/var/www/vhosts/example.com), and you wish to create additional ftp users (jill and bob) with the same access privileges as jack:

Procedure:
Login to server via SSH as root.

Issue the shell command:

#cat /etc/passwd |grep ‘jack’

This will show you a line similar to the following:

jack:x:10041:10001::/var/www/vhosts/example.com:/bin/false

The first number (after the 2nd colon : ) is 10041, so this is the UID of user jack. You will need this in the ‘useradd’ lines since useradd wants a number for the UID.

The second number (after the 3rd colon : ) is 10001, this is the GID (psacln), we won’t need that right now.

Then run the following shell commands to create the users and passwords:

#useradd -u 10041 -o -d /var/www/vhosts/example.com -g psacln -s /bin/false jill
#useradd -u 10041 -o -d /var/www/vhosts/example.com -g psacln -s /bin/false bob
#passwd jill (enter the new password and confirm it, does not have to be the same as jack’s)
#passwd bob (enter the new password and confirm it, does not have to be the same as jack’s)

You should now be able to use an FTP client to login with that user’s name and password.

User jill and bob should be able to see the example.com docroot just as user jack can. You should NOT be able to browse above the example.com docroot directory. All 3 users should have the same access to the files since they belong to the same group, so no matter which of the users created or edited the file(s), all should be able to access/edit/whatever the same files.

(NOTES: Since these are users defined at the OS level, when connecting with an FTP client, they would login with username ‘jill’, ‘bob’, or ‘jack’. They would NOT use ‘jill@example.com’. This also means that USERNAMES MUST BE UNIQUE.)

Subdomain FTP users:
If you wanted to change their default directory and limit them to a Plesk created subdomain docroot, in the useradd line above, you would change “/var/www/vhosts/example.com” to “/var/www/vhosts/example.com/subdomains/subname”. So if you wanted to create the same users, but for a subdomain called ‘admin’:

Then do the following shell commands to create the users and passwords:

#useradd -u 10041 -o -d /var/www/vhosts/example.com/subdomains/admin -g psacln -s /bin/false jill
#useradd -u 10041 -o -d /var/www/vhosts/example.com/subdomains/admin -g psacln -s /bin/false bob
#passwd jill (enter the new password and confirm it, does not have to be the same as jack’s)
#passwd bob (enter the new password and confirm it, does not have to be the same as jack’s)

Deleting an FTP user:

#userdel jill

(Note: this will not delete any files unless you use the -r option which you probably don’t want to do if they are sharing files!)

Thanks! Works like a charm.

Blaine | May 27th, 2009 at 4:00 am
This is great – thanks! BUT can I restrict “jill” from uploading or deleting or changing file names in this shared folder? THAT would be truly awesome. Using proftp, btw.

ankur | May 27th, 2009 at 3:17 pm
Thanks for your comment. But you can’t restrict “jill” from uploading or deleting or changing file names in this shared folder, because the other FTP user “jill” having the privilege of actual FTP user “jack” who requires full permission to manage the other folders/files.

Blaine | May 27th, 2009 at 8:54 pm
Thank you so much for the quick reply, but IS there a way to have jill just be able to read?

Blaine | May 27th, 2009 at 10:40 pm
I figured it out. I made the UID and GID unique, then assigned the appropriate rights to the folder. This post was very helpful. Thank you.

Daz | June 6th, 2009 at 9:51 pm
Blaine – could you elaborate on how you changed UID/GID to restrict access to folders. What I’m trying to do is not only create multiple accounts on a subdomain (success) but restrict those accounts to specific directories within that doman, so that user Bob can only access his Bob directory that I set up under httpdocs.

ankur | June 8th, 2009 at 11:18 am
Hi Daz, Thank you for your comment, you can run the command as below:

useradd -d /var/www/vhosts/example.com/subdomains/subdomain-name/bob -s /bin/false bob

It will set the UID and GID unique, and then set the other users read permission only on the folder bob. This will make the other user (bob) can only read the files/folders. And as the user shell set to /bin/false, which will restrict the account to specific directory within that domain.

Tony Bianco | June 9th, 2009 at 3:21 pm
This is great, because I’m using Media Temple’s DV plan and they use Plesk. I’m needing to create multiple FTP accounts for the same domain but I need to restrict their access to a particular folder.

Also, I need that folder to not be in an area of the webroot where the public can access that folder.

How would I accomplish this?

ankur | June 11th, 2009 at 12:13 pm
Hi Tony, thank you for your comment, here we go
Create a folder anywhere you want, e.g. “/var/userftp/tony” then run the below command to create FTP user:

useradd -d /var/userftp/tony -s /bin/false tony (set the password)

And then use “chmod” command to set require permissions.

Tony Bianco | June 13th, 2009 at 1:55 am
Ankur,

Just so I’m understanding this correctly, because I’m new to this.

I would I issue the following commands to add a new FTP user that would be able to access a folder via FTP:

useradd -d /var/someFTPFolder -s /bin/false myUserName myPassword

Is that correct?

And is there way to assign that user to a general folder and then a user specific folder?

ankur | June 13th, 2009 at 3:06 pm
Tony,

“useradd -d /var/someFTPFolder -s /bin/false myUserName” is correct.

Change the user home directory path as per your choice (general folder or user specific folder), e.g. “/var/some-other-FTPFolder”.

Regards,
Ankur

Tony Bianco | June 15th, 2009 at 2:44 am
Thank you very much! If I ever want to change a user’s password how would I do that?

ankur | June 16th, 2009 at 1:30 pm
Thanks Tony, run the below command to change user password:

passwd username

Regards,
Ankur

Flex Application Development Process

• Define an application interface using a set of pre-defined components (forms, buttons, and so on)
• Arrange components into a user interface design
• Use styles and themes to define the visual design
• Add dynamic behavior (one part of the application interacting with another, for example)
• Define and connect to data services as needed
• Build the source code into an SWF file that runs in the Flash Play

Development Methodology

gives u sql version

select @@version;

 SHOW GLOBAL VARIABLES LIKE ‘version_compile_machine’;

first note your version numbers

gem -v

ruby -v

rails -v

then make sure your system library is up to date 

$ sudo gem update –system - this command updates the ruby gems package manager (this update is required by the latest version of rails)

$ sudo gem install rails - updates and installs the latest version of rails including the dependencies

$ sudo gem update rake - updates the rake tool which is used by rails

$ sudo gem update sqlite3-ruby - updates the ruby sqlite3 bindings, you can skip this command if you don’t use sqlite as your database

Testing

You will get visual updates as the update process goes on but if you still feel like testing the update once you are done, type this command in the terminal

$ rails -v

and to get a list of all the gems currently installed on your mac displayed with their version numbers use the following command

$ gem list

rails shovell -d mysql 

rails [appname] – mysql

if u using sqll lite do the following

#rails api -d mysql
