[Mono-list] on connecting to Sybase

Did you try setting the port to be different?

You were orginally trying to set the port to 5510, but the SybaseClient
provider defaults to 1533.  Either set it to listen to 1533 on the server,
or modify the SybaseClient source code to set the port to 5510.

This is the nice thing about open source software; you don't have to wait
and depend on a vendor to come out with the next release (if they do fix
your problem in the next release).

After I changed to:

string constr =
    "server=10.34.7.41;"
    +"user id=rbsdbo;"
    +"password=rbsdbo;"
    +"database=ccb;";

Then I got different exception  as following:

D:\exdir\mono>monooledb

Unhandled Exception: System.Net.Sockets.SocketException: No connection could
be
made because the target machine actively refused it
   at System.Net.Sockets.Socket.Connect(EndPoint remoteEP)
   at Mono.Data.Tds.Protocol.TdsComm..ctor(String dataSource, Int32 port,
Int32
packetSize, Int32 timeout, TdsVersion tdsVersion)
   at Mono.Data.Tds.Protocol.Tds..ctor(String dataSource, Int32 port, Int32
pack
etSize, Int32 timeout, TdsVersion tdsVersion)
   at Mono.Data.Tds.Protocol.Tds50..ctor(String server, Int32 port, Int32
packet
Size, Int32 timeout)
   at Mono.Data.SybaseClient.SybaseConnectionPool.AllocateConnection()
   at Mono.Data.SybaseClient.SybaseConnection.Open()
   at Sample.Main()

So I think I should wait the new release.
Thanks a lot.

None of Mono's data providers has ability for trusted_connections.
So, the connection string is wrong.  The port defaults to 1533.  I couldn't
find a way to set the port.

Maybe, you can set up your Sybase server to listen on 1533.  Or, you could
modify Mono.Data.SybaseClient source file SybaseConnection.cs to set the
port.  I'm sure Tim will take patches.

Anyways, try this connection string:

string constr =
    "server=10.34.7.41;"
    +"user id=rbsdbo;"
    +"password=rbsdbo;"
    +"database=ccb;";

just guessing, but could it be that it is using the port number as part
of the hostname, and that's why it can't connect? I'm not sure if the
connection string is ok or not for the Sybase provider, so maybe Tim can
tell you if it's so or not.
