DB: Sybase Anywhere10 on WindowsXP
Client: Sybase Anywhere11 on RHEL (Linux) 5.4
ODBC: unixODBC 2.3.1 on Linux

Trying to connect remotely to a Sybase Anywhere 10 database running on WindowXP Professional SP3 from a Red Hat Enterprise Linux 5.4 using a Sybase Anywhere 11 client and unixODBC 2.3.1 (64-bit).

unixODBC isql tool does not connect -- gives following error:

isql -v txeis dba sql
[08001][unixODBC][Sybase][ODBC Driver][SQL Anywhere]Database server not found
[ISQL]ERROR: Could not SQLConnect

I can ping the remote server where the Sybase database resides. I can see that the default port (2638) is open. I can connect to this database using Sybase Central from my PC, which of course is remote.

================================
Is anyone aware of any issues with this configuration? I am able to connect with another configuration similar to this -- i.e. it is identical except the Sybase database is local.

Your configuration is for local network server (bold line is name for ServerName of your database on local computer) to connect to remote server add this line to your odbc.ini file:
