Can't connect to Sybase ASE server from PHP

Hello, I am trying to use PHP with the Adaptative Sybase Enterprise server that came with Red Hat 5.2. I have installed following the quick start howto document. I was able to put the main SYBASE and the SYB_BACKUP servers to run during Linux boot and I can login the servers doing isql -Usa -P. DBA user name is sa and password is empty. My only problem is that I am not able to connect to the SYBASE server from PHP. I just try to run a simple script like as follows using php standalone executable, and it produces the error message below. <? sybase_connect("SYBASE","sa",""); ?> <br> <b>Warning</b>: Sybase error: (severity 0) in <b>x.php</b> on line <b>2</b><br> <br> <b>Warning</b>: No such host as SYBASE in <b>x.php</b> on line <b>4</b><br> My interfaces file in /opt/sybase/interfaces contains this ## SYBASE on cohones ## Services: ## query tcp (7100) ## master tcp (7100) SYBASE query tcp ether cohones 7100 master tcp ether cohones 7100 ## SYB_BACKUP on cohones ## Services: ## query tcp (7110) ## master tcp (7110) SYB_BACKUP query tcp ether cohones 7110 master tcp ether cohones 7110 My php3.ini file sets sybase.interface_file = "/opt/sybase/interfaces" The showserver command returns this: USER PID %CPU %MEM SIZE RSS TTY STAT START TIME COMMAND sybase 1291 0.0 5.1 16264 6576 p2 S 04:04 0:00 /opt/sybase/bin/dataserver -d/opt/sybase/master.dat -sSYBASE -e/opt/sybase/install/errorlog -i/opt/sybase sybase 1293 0.0 3.1 6700 4084 p2 S 04:04 0:00 /opt/sybase/bin/backupserver -SSYB_BACKUP -e/opt/sybase/install/backup.log -I/opt/sybase/interfaces -M/opt/sybase/bin/sybmultbuf -Lus_english -Jiso_1 -c/opt/sybase/backup_tape.cfg All seems to be correct but I have no idea what is still wrong.
