Re: [twsocket] Strange SSL-components problem
Hi, at first you should get atest ICS source code and OpenSSL DLLs from http://wiki.overbyte.be/wiki/index.php/ICS_Download The problem with undeclared identifiers is easily solved by rebuilding the project, a simple compile is not enough after changing the USE_SSL directive. -- Arno Garrels Dimitris Botsis wrote: Hi all, I have a very strange problem with ICS. I try to use ICS v7 (Oct/2010) fresh downloaded from you website (overbyte.be). I install it on Delphi 7. All is OK when starting. I have an empty form and drop 2 components on it : - a Tsslhttpcli - a TsslContext I have already included the proper paths for ICS in the Delphi environment so when I build it's all OK and for SSL I use ssleay32.dll and libeay32.dll but due to problems of versions I have disabled SSL version checking from OverbyteIcsSslDefs.inc. After some builds of the same project, without having changed anything in the project, I get the error that Tsslhttpcli and Tsscontext are undeclared identifiers, although previously they were fine. If I close and open Delphi and project again, problem is still the same. The only way to correct it, is to delete all contents of Delphi/Vc32, copy there fresh files from the downloaded zip from Overbyte's website and rebuild again the OverbyteIcsD7Run.dpk. Then it starts working fine for some time tries until it stops with the same errors again after some builds. This happens only with SSL components of ICS, with other components everything is OK. Even when the 2 components I refer to seem to be undeclared identifiers if I use another non-SSL component (before rebuilding-that solves temporarily the problem) all other work fine. Please note that : - I don't have any other problem with no other components installed - When I manage to compile project correct, then executable file is fine for always. The problem appears only in the Delphi environment together with ICS, while in build process.

Hi Arno, thank you for replying. I rebuild the project every time the problem occurs. I even uninstall the whole package and install it again. First times it works fine without problems.

Re: [twsocket] Strange SSL-components problem
Hi all, I corrected the problem, thank you Arno and Francois for helping. I did not have USE_SSL enabled but although it was not enabled, the first times the build was succesful with SSL support - I don't know why.

Re: [twsocket] Strange ICS proxy server in service app problem
I have made some more tests on my Win7Pro and saw that MS was clever enough to raise the 1 handles per process limit in newer Windows'. I think the new limit is something like 24-25000.

Re: [twsocket] Strange ICS proxy server in service app problem
Hi Arno, Not sure how the debug GUI exe works but I found a solution for the service: In ...WndControl.pas, const TIcsWndControlVersion = 110; CopyRight : String = ' TIcsWndControl (c) 2002-2008 F. Piette V1.10 '; WH_MAX_MSG = 400; == MODIFIED THIS from 100 so that it would create less windows per same number of messages. With this change, My also ICS stress tester can open 15k connections concurrently. In a real life case, since there will not be a stress tester on the same machine, I think it is ok. This must be a non-paged RAM drought issue... Could you make WH_MAX_MSG a property so that each time users update ICS, they would not need to change ICS source?

Re: [twsocket] Strange e-mail problems Server 2003
Hello Arno, I see in the log that there is 5 seconds delay between DATA and the 10054 error. This may be interesting. During this delay do you send data ? I say this because some server will close cnx if no data transmitted fast enought and do not receive data for xx seconds, usually the timeout is between 1 or 3 minutes but I know a server that wait only 3 seconds (may be bad configuration). The best is to ask client to manualy telnet port 25 into the server and type a SMTP sequence and wait 5 seconds betweent each line you type. Also may be there is some check-back cnx to the client's machine and if FW is ON then machine cannot be checked. regards.

Re: [twsocket] Strange Vista winsock behavior--any way to by-pass?
From the limited exposure I've had to Vista (Home Basic) client use. A Clean install on the same hardware (P4 2GHz, 512MB Ram, 80G drive, nVidia graphics) it run's at about half the speed of XP(Home) in just about all respects. Whatever tweaks you do to it. Where'd the Wow go? Less than impressed (we re-installed XP as a result, did all the updates, and the same machine really rocks again!) Of course, the reseller will not take it back as the box is opened, will hang on to it till we can get something bigger better and much faster to load it on.

Re: [twsocket] Strange
TnClient is behaving the same strange way. TnClient displays: Connecting to xxx.xxx.xxx.xxx and then Connected but the welcome banner of the server is displayed with 20-30 secs delay. On the other machine, the welcome banner is displayed right after Connected. My gues is it can be an OS bug, on the specific hardware platform (ethernet NIC, etc.). I've downloaded a packet sniffer, and 3 packets are captured when the connection is initialized: one from the client to the server, one from the server to the client and again, one from the client, and then the data transfer is delayed. The server is build around ucspi-tcp from http://cr.yp.to, on linux. On short, the tcpserver program is listening on a specified port and when a connection is established they launch an external program, rewriting input/output filedescriptors of that program on the incoming socket. It works very well, as it is also used for the (*nix users wellknowed) qmail. 10x again, / Ionut Muntean -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Francois PIETTE Sent: 6 decembrie 2005 07:56 PM To: ICS support mailing Subject: Re: [twsocket] Strange The telnet connection on the specified port on the server is working well. :( OK, so let's try with one of the ICS provided demos so that we are sure you have not a bug in your own code.

On the other machine, the welcome banner is displayed right after Connected. It is possible that the server has problem sending data packets to the client. I have no idea why because connection initialization packets are transmitted without delay. To help you withthe sniffer: A TCP session is established with a 3 control packets (without mention ARP packets to resolve IP/MAC addresses): Client send SYN Server respond with SYN-ACK client respond with ACK then data and ack packets are sent/received by either party. -- Contribute to the SSL Effort.

Thanks Wilfred, but I need to send the next message only after I receive the
