I want to incorporate into a piece of software the ability to look up a manufacturer based on a mac address. By googling "mac address lookup" and similar, I have noticed several websites that make this correlation which suggests this data source is available somewhere. Where can I find this data source that correlates a mac address (input) with a manufacturer (output)?
I'm new to Linux.
I am working with a Redhat 5.5 server and am using a Java-based SFTP script that will allow multiple users to upload text files to a server. I am undecided if each user will have a separate directory or if I will use a naming convention that includes their customer ID.
The files include some personal information about their LAN settings, so I prefer to use SFTP as apposed to FTP. It is my understanding that SFTP is encrypted (Also, I have a Java class configured to upload via SFTP, so I prefer not to switch protocols unless their is a very-good reason).
The prototype is for a system that will support large numbers of customers and the thought of continually adding and removing clients through the command line seems highly impractical. (Again, I am new_to/learning Linux and Redhat).
What are normal conventions for giving multiple users permission to SFTP upload files with a unique username and password for each.
I just ran yum install php in the command prompt. Everything went fine ('complete!') as per the dialogue. I then uploaded a file that does not use short tags and is named with the proper extension (i.e., the name is test.php).
<?php print "hello world"; ?>
When I navigate my browser to test.php it just prints each of the characters shown above; i.e., PHP is not interpreting it.
What might be the problem? Also, if there is a configuration file that needs to be updated, please tell me what directory path I am likely to find that file.
Edit: Apache2 & Red Hat Enterprise 5.5
I'm new to setting up servers, working with Apache2, etc. While attempting to post html documents, I:
- dropped a html file in the 'www' directory.
- ran this command in the command prompt:
iptables -I INPUT -p tcp --dport 80 -j ACCEPT - visited the appropriate URL.
However, I am directed to a 404 not found page.
I am setting up diagnostic servers on local networks (Redhat 5.5). One requirement is a speed test where users in the network can test the speed of their internet connection (e.g., http://speedtest.net/ ).
I have been given the impression that their are open source solutions that I can use. I'm not sure yet if it makes a difference, but sometimes users might be accessing the speed test through a web page and sometimes the users will get the data from a Java application I am building.
I need to install LAMP (including Perl) on a Redhat 5.5 machine. (Note: I am fairly new to Linux, but did do a similar project with ubuntu.) A good tutorial might suffice. Clients need to access a cgi-bin to run perl scripts (I don't yet know a lot about running perl scripts on the server side).
I found two tutorials that specifically mention RedHat (and are less then a year old according to Google). One seems simple and the other seems complicated:

Other suggestions (as a replacement or supplemental) are appreciated.
