_______________________________________________________
from the command line it works fine
i.e php add-entry.php works fine ( ofcourse adds an empty row into the data base)
--------------------------------------------------
i did telnet
[root@localhost html]# telnet localhost 5432
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
Connection closed by foreign host.
data/pg_log/postgresql-Mon.log contains
LOG: invalid length of startup packet
-------------------------------
I am not getting any clue as to how to solve this problem ...let me know if you have any idea in solving this porblem.

Hi ,
in my last mail i forgot to mention that i have restarted apache server after making changes to the httpd.conf.
Today i made one more experiment ...
1. changed httpd.conf
user apache
Group apache
DocumentRoot="/home/murali/html"
<DocumentRoot "/home/murali/html">
......(as it is)....
<DocumentRoot>
2. copied the files add.html and add-entry.html to directory html under my home directory i.e
/home/murali/html
3. restarted apache
/usr/sbin/apachectl start ( from root)
4. from postgres login started postmaster.
postmaster -i -D data&
5. http://localhost/add.html ( entered Name , Phone , Email)
EVERY THING WORKED !!!!!
BUT CAN ANY ONE TELL ME, WHAT WAS THE PROBLEM WITH EARLIER SETTING AND WHAT MADE IT TO WORK PROPERLY NOW !!! I NEED TO ANSWER THESE QUESTIONS
Thanks for all of your help
regards
Muralidhar
