Hi,
I would like to delete the message "Connection timeout expired" when the IP address is not correct ... or catch other error,
How to do that ?
I try this but without success ...

try
ScSFTPClient.Initialize;
except
on e: EScError do
begin
AddDebugString('Error : ' + e.Message);
end;
on e: EScSFTPError do
begin
AddDebugString('Error : ' + e.Message);
end;
end;

Thanks.

I create my own Exception handler ...
But, with the SocketException the program freeze 10 seconds and I can not change this timeout, also the timeout in SSHClient or SSHShell does nothing ...

procedure TRootForm.MyExceptionHandler(Sender : TObject; E : Exception);
begin
if ((E.ClassName = 'SocketException') or (E.ClassName = 'EScError') or (E.ClassName = 'EScSFTPError')) then
begin ...

The problem is that if you set the Hostname property to a server hostname, then SecureBridge uses WinSock API 'gethostbyname' function to retrieve corresponding host information. This function returns result only after 3-10 seconds if the hostname is invalid, and SecureBridge can't influence it.

I set the ScSSHClient.hostname with an IP address ?!

When you use IP address then the WinSock API 'connect' function is executed, and this takes much time when this address does not exist.
