Exercise: Complete Pre-Installation Checks 

Let's make sure we have the necessary requirements for beginning the installation.
 

1. Check for proper OS (Solaris 2.6).

a. Open a shell window, and type
# showrev
b. Near the end of the output, you should see  "Sun OS 2.6" or "Sun OS 5.6" (both are equivalent).


2. Check for sufficient disk space (>255MB).

a. Open a shell window, and type
# df -lk
b. This will list the available space on your local hard disk(s).


3. Check for nothing running on the SMTP, POP3, or IMAP4 ports (25, 110, 143)

An easy way to do this is to look at all the ports your machine is listening on, and look to see if 25, 110, or 143 are listed.

a. Open a shell window, and type

# netstat -an | grep LISTEN 
b. The first column of numbers are port numbers.  Make sure 25, 110, and 143 are not listed.


4. Make sure you have a Directory Server available.

The Directory Server runs on port 389, so this time make sure port 389 is being listened to.

a. Open a shell window, and type

# netstat -an | grep LISTEN 
b. The first column of numbers are port numbers.  Make sure 389 is listed.
