Hello, I am running Zope 2.1.6 under Linux/RH6.2 on a PC. The Sybase server is version 11.9.2 on a Solaris station with DNS name "sybstat" on port 2040 (or sybase server name "sybtest") and the database is named "picsou". When I try filling in the form to add a new Sybase DA connection, the result is always: Invalid connection string. I have try with this parameters : 1-database: picsou, password: mypasswd, server: sybstat, user: myuser 2-database: picsou, password: mypasswd, server: sybstat:2040, user: myuser But this give the same answer ... On Linux, I have the libraries, include files and all running client for Sybase and I can run isql from my PC on the Sybase server on the solaris station very well using the parameters of the (2-) set. So the connection to the Sybase server seems to work ... How could I check what happens inside Zope, or am I mistaken for the parameters values ? Thanks for any help. Tony
