Problem with connect to Remote Sql Server 2000 from centos 4.5 with PHP


Hi to all.
I have problem with connection to mssql 2000 from centos. i have installed php, freetds, unixOBDC on server Centos. My mssql server on another computer (windows xp). Now, when i tried to connect mssql with php :

>> mssql_connect("192.168.179.100","sa","sa")

Centos return to me "Unable to connect to server: 192.168.179.100 in /var/www/html/work/test.php on line 15 "

can anyona help me, please..

note: mssql is running on windows, and user and password is same "sa".

First just try to connect using the command line client not php. On your centos machine do
Code:
mysql --host=192.168.179.100 --user=sa --passord=sa
If this also fails then you will know that it is an issue with the server configuration: best look in the documentation for mssql for you xp box.

If it works, we can start to try to isolate the problem within the php.

my database is MSSQL. i try command like that:
>> tsql -H "192.168.179.100" -p1433 -U sa -P sa

but now except this message :

Msg 10018, Level 9, State 0, Server OpenClient, Line 0
The connection was closed
Msg 20014, Level 9, State 0, Server OpenClient, Line 0
Login incorrect.
There was a problem connecting to the server
You have new mail in /var/spool/mail/root

Ok, but the server logs should give more useful information about why the login was not accepted. Another thing to check is if the command line client has a verbose option: for example with mysql that would be the --verbose or -v flag.

Ok, you can try to ping the sever and also try to port scan it to see if the connection is being made. On the centos box:

Code:
ping 192.168.179.100
nmap 192.168.179.100
You should at least be able to see port 1433 open.

ok, i done. ping goes normally. but after this command , shown result :

Starting Nmap 4.76 ( http://nmap.org ) at 2010-02-08 12:47 AZT
Interesting ports on trixbox1.localdomain (192.168.179.100):
Not shown: 994 closed ports
PORT STATE SERVICE
80/tcp open http
135/tcp open msrpc
139/tcp open netbios-ssn
445/tcp open microsoft-ds
912/tcp open unknown
3389/tcp open ms-term-serv
MAC Address: 00:1F:29A:A3:74 (Hewlett Packard)


so, port 1433 is not shown this list. whats it mean? port is closed on database server or linux cant see it?

Looks like it is closed.
If it's open, nmap should have seen it. Perhaps it is being blocked by a firewall. Is your centos client box on a different subnet to the boxes which can connect?

hmm, so, i must open 1433 port on my database server. i think that this port must be opened on mssql server starting. can you say, if my 1433 port is closed, can another client connect to this server? i cant understand your question. My centos client connected to internet.

You said in post #5 that some windows clients can connect to the server ok, but your centos client can not. Ie the windows clients must see port 1433 as open, but the centos client sees it as closed. So, I was wondering what is different (if anything) about the network(s) that the windows clients are on compared to the centos client. Is the sql server behind a firewall that only opens 1433 for certain client IPs or networks?
