Error connecting to server via TCP/IP
Gordon Scrim
I am wondering if anyone can shed some light on a problem one of our
customers is having. They are unable to connect to Interbase using
TCP/IP. The server is Win2K AS and Interbase is 5.6 When at the server
using the Communication Diagnostics the local server can be connected to
OK but if the remote server option is used the following output occurs.
Path Name = C:\WINNT\System32\gds32.dll
Size = 347136 Bytes
File Time = 20:56:00
File Date = 09/07/1999
Version = 5.6.0.29
This module has passed the version check.
Attempting to attach to 192.168.0.1:C:\Data\TestDB.gdb
An InterBase error has occurred while attaching.
Error - Unable to complete network request to host "192.168.0.1".
Failed to establish a connection.
I have tested the TCP/IP setup and all is working OK. The same error
occurs if I use the localhost address as well.
The strange this is that this server was working fine until it was
restarted yesterday for some reason. Of course no-one has touched
anything on the server that may effect IB!
Many thanks if someone could give me a few pointers as where to go next.

probably you haven't installed proper remote connection licenses on your
server and the "eval" license has expired :).

The IB installation is correctly licensed and does not use the eval license.
I have tested the id and key on another installation and it works fine. I
wondered if the user had stuffed around with the permissions that the IB
processes run under but of course the user hasn't touched that :).

In IB docs is described that is necessary to use Server Name not IP

The use of an IP Address instead of an host/computer name is valid, and
supported by some TCP/IP stacks -- the documentation is showing it's age
in this respect.
For MS Win, versions with Winsock v2 all support the use of IP
Addresses.

IP Add, or name.

I had a similar problem with Win 2000 and resolve it with host names.

I have tried several computers with WinNT and Win95, and all behaved
the same way - the connection (using IP address) was established,
but only after veeeery long time, so it is practically unusable.
Is there any way how to speed it up?

You can upgrade Win95 to use winsock 2, then it will "work" too.

may be you have no DNS server on the network ?:

Anyway, yes, I have DNS server. Connecting with computer name is fast,
connecting with IP address is slow. What should I do
(I do not consider hardcoding ip-address/name in hosts file a solution).

you restart Windows NT/ 2000 Routing Service (by some reason) or something
unusual, exist probability for IB crashing if connection is by IP.
This is my experience :)

the same access time).
but when you connect to a server, if you have a DNS server, the first frame
is for the dns server to resolve the address and
perhaps it will take a long time if the adress is xxx.xxx.xxx.xxx because
the dns server add the domain name to that address to search for. Then the
client send a broadcast ARP trame to get the MAC address. The TCP connection
on port 3050 begin after
then you should try to connect after clearing the address of the dns server
on the client side. If it doesn't work, may be you have
problem with broadcast (some active element in network may filter
broadcoast)
