Re: 回覆： Re: 回覆： Re: [twsocket] ThttpCil S end bufsize problem
Hello Opqrst, HttpCli1-CtrlSocket-BufSize property, and I don't know how to set can more than 8193 even to 32768 or You can set this to any value (it's integer), but if you let it default you will probably have best performance. Because by this way I can Upload with my full upload connect speed. Changing the buffer size will not change upload speed. This because, as Francois already have mentioned, ethernet packet size is 1514 bytes. If you have PPP connection then packetsize is 512 bytes. This is low level and nothing to do with ICS or any other components. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Wednesday, January 11, 2006, 21:56, Opqrst Ghrst wrote: Hi I want to change the send buffer just like Tidhttp it property SendBufferSize , at ThttpCli I only change it to max 8193 limit by set HttpCli1-CtrlSocket-BufSize property, and I don't know how to set can more than 8193 even to 32768 or more.

Re: [twsocket] Process pooling for CGI
You may then consider the tiny CGI concept. You create a very small CGI which load very fast (you can build one being less than 150KB and maybe even less than 100KB and still doing useful things). This CGI would load the DLL which would do the real work. If you manage to also load the same DLL from your server, then the DLL will remains always in memory (DLL is shared by all executables provided the load address is compatible with all executables). Instaed of a DLL, you may make the CGI a gateway to your server (or another one), using any IPC you like.

Re: [twsocket] ThttpCil Send bufsize problem
http://img79.imageshack.us/img79/2092/ics0rl.jpg I don't know what your WPEPRO1 shows, but for sure it is _not_ IP packet size. Maybe WPEPRO1 show the dialog with winsock API and this is _not_ directly related to line speed. The size of data writtent to winsock at one time affect line speed only if your CPU is not fast enough to have enough system calls to fill winsock buffer. It is for sure never the case with ADSL with even the slowest CPU. But with gigabit link, you need a very fast CPU of course to sustain the gigabit line speed. To see packet size, you need to use a packet sniffer such as ethereal. Link on the links page at my website. I know Change buffer size cannot change upload speed, But I use ADSL 8M / 640 kbps it should has max upload speed with 80 kb/s. if I send every packet size 32768 it can up to 50kb/s speed. by 8193 only has 20kb/s speed. I want to use my max upload speed and how can I to do? You automatically have best transfert speed. No need to change buffer size, defenitely. You have the best overall speed, use asyncronous operation only (use GetAsync, PostAsync and so on). btw: You have unreadable characters in your subject line, at least seen from here. -- Contribute to the SSL Effort.

Am I naive to think that I can come up with a solution for a Telnet/S with file xfer options(xyz-modem)? ICS handles SSL telnet quite happily, you would just have to add the zmodem protocol on top, which you can find for free on the internet, it's part of the Turbopower Async Pro package. Just sent the data as TCP/IP packets instead of async packets. But it's unlikely anyone will have done such an implementation already, zmodem is unnecessary in the TCP/IP world which already has handshaking and error correction. It's also not very efficient, I use an application daily that downloads and uploads using zmodem over TCP/IP, and throughput is poor due to continual acknowledgement packets.

Re: [twsocket] TIcsSocket - Socket.Close locks up - 99% CPU
Hi Peter, I had similar experiences and had to delay my Linux implementation. I have wanted to review the Kylix code and try and fix it as I think that this will add huge value to everyone here, myself included. I think that I know where to start looking for these problems. In short the Kylix implementation uses threads heavily and it's not synchronizing correctly. I have allocated time in March and April this year to sort this out so if you can wait until then, then we may have a fix. If you are willing to get involved in the process, please let me know.

The problem is when the client disconnects, My program runs at 99% CPU and the loop is in the IcsSocket.Close method.

[twsocket] UDP TTL setting
Is it possible to manually change TTL (time to live) for an UDP packet? -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Newbie- Telnet SSL with zmodem transfer
how do you make async packets into tcp/ip packets. A packet is a string of characters, it's independent of whether it's being sent using serial comms or TCP/IP. I'm not saying it will be easy to extract the Async Pro Zmodem code, but it can be done, if you don't want to pay for a package that includes it already (and if there is one). I'd done two jobs where private async protocols are converted to TCP/IP, trivial really.

Re: [twsocket] TIcsSocket - Socket.Close locks up - 99% CPU
Hi Erich Thanks for your reply, at least I'm not the only one. I did find a workaround though, which was not to close the sockets in the OnSessionClose event but I HAD to close the socket in the OnClientDisconnect event of the Listener, before I freed the client object. It appears that when a client disconnects, the OnSessionClose and the OnClientDisconnect events don't always get called in the same order and the state of the Socket isn't always consistantly closed. By forcing a close in the OnClientDisconnect event seemed to make it more stable. I am interested in getting this working and will help where I can, as I have based my new project on this component. BTW, if anyone is interested I have written a simple wrapper around TWSocket and TICSocket so that I can compile my project for both windows and linux (with the same code base) using CrossKylix on Delphi 2005. Hi Peter, I had similar experiences and had to delay my Linux implementation. I have wanted to review the Kylix code and try and fix it as I think that this will add huge value to everyone here, myself included. I think that I know where to start looking for these problems. In short the Kylix implementation uses threads heavily and it's not synchronizing correctly. I have allocated time in March and April this year to sort this out so if you can wait until then, then we may have a fix. If you are willing to get involved in the process, please let me know. I did look for volunteers some time ago, but only got a few responses from people saying that they could provide high level input.

It is a console tcp/ip server app running on linux. It accepts connection from clients and sends data to each of the clients. The problem is when the client disconnects, My program runs at 99% CPU and the loop is in the IcsSocket.Close method. When the client disconnects, the SockServerClientDisconnect is triggered which frees my client object that was created in the SockServerClientConnect event. In the destroy of my client object I close the IcsSocket by calling Close. If Socket.State = wsConnected then Socket.Close; It is here that there is problem because the IcsSocket.close function never returns. I know there are worker threads involved so it could be related to my main thead loop which is shown below. while not bTerminating do begin CheckSynchronize(1); end; p.s. I am running the ics-kylix beta 4.

Just sent the data as TCP/IP packets instead of async packets. i do have asynch pro and have used it before turbopower quit, but only for serial connections not tcp stuff. its the last part - instead of async packets that i have no clue about. how do you make async packets into tcp/ip packets. i've searched the async list but can't find anything there to get me started. tia.

[twsocket] TIcsSocket - 6 Sec Delay in Listener actually Listening
Hi I am having a problem with the kylix version of ICS at the moment. It is a console tcp/ip server app running on linux. It accepts connection from clients and sends data to each of the clients. The problem is when I start the Server listening with the Socket.Listencommand. It doesn't start Listening straight away, it takes sometimes up to 15 seconds to actually start listening for connection. When i do a netstat -a when its in this state, there are client processes trying to connect to the listener in TIME_WAIT state, which I think is the problem, probably when these connections timeout is when the Listener start listening. But this should not be the case and isn't normally the case with sockets as far as I know. It certainly isn't this way using TWSocket on Windows. Any Ideas would be appreciated.
