Re: [twsocket] MagFTP Upload Speed
Also informing you that as far as Excludes are concerned the option you have given suits me well I realised it would help me as well. When I synchronise my local web sites with my public server using delete old files, the ICS SVN files all disappear since they are generated by scripts on the server, so I need to exclude that directory.

Re: [twsocket] Close connection (destroy) idle clients
Hello, I could use the component TWSocketServer based on this example: http://edn.embarcadero.com/br/article/20465 now it seems to be working perfectly connecting to POS terminals That article was written by Francois, so I'm sure it's fine. I doubt it's any different to the existing ICS demos. when the connection is terminated the client side, or simply strip the cable network, the server is terminated after some time (timeout)? If the remote client properly disconnects, the server client should drop. If the connection drops unexpectedly when no traffic is being sent, there will be no disconnection so you need to implement a timeout. Look at the ICS FTP server which does exactly that. Basically you use GetTickCount to set a variable to indicate when each client connects and when data is sent or received, then have a single global timer firing every five seconds which checks each client in turn and disconnects any that last had activity two minutes ago or whatever you need. Don't use a timer per client.

Re: [twsocket] MagFTP Upload Speed
1) In case I have to upload some data (eg: 5GB). How can I get to know approximately how much time it will take ? Use CopyEvent, LogLevelProg gives you an ASCII string every couple of seconds showing how much has been transferred and the total size. Unfortunately from your perspective, the response is friendly format, ie 4.5Mbyte of 2.6Gbyte, which you'd need to parse with the time taken so far to estimate the time left. The internal variables are not available in the event. The component does report the time and speed at the end, but that does not really help you. To do it properly really needs a new LogLevelSpeed type in the procedure onFtpClientProg64 that does all these calculations and gives an ASCII response. I'll put it on the wish list, with exclude sub-directories. 2) Just wanted to know if there are any size limits for upload with ICS/MagFtp ? No real limits, I've tested file transfers of DVD size, but nothing larger. But MagFtp only uses a single socket at a time. If you want more efficient uploading of single large files you would be better looking at OverbyteIcsMultipartFtpDownloader (no uploader) that splits a large file into chunks and does multiple parallel transfers.

Re: [twsocket] Close connection (destroy) idle clients
Hello, the protocol used is TCP, TCP/IP is a transmission mechanism, not a protocol, those are commonly named HTTP, FTP, SMTP, etc. the POS terminal sends to the server is a string of ASCII characters like this ACTION=VENDAID_TERMINAL=528-533-378ID_EVENTO=1579ID_SETOR=00 018087QTDE=01TPEMISSAO=0TIPO=0MAG=0 The text may be ASCII, but there are no line endings so it's not a line oriented protocol, it's more like an HTTP POST response. what happens is that after some transactions by sending the string to the server, the event OnDataAvailable is no longer triggered, Using linemode false or true? Are you expecting more data? this happens only with the component TWSocketServer, since the component TWSocket this problem never happens TWSocketServer uses TWSocket, no difference. So the difference must be between the ways you have implemented the code. I also did the test with TMagIpLog and the same problem happens Sorry, can not explain that. Except TMagIpLog is heavily used in my own applications and never loses data. I would refer back to my previous comment about creating a test application, you can use TMagIpLog in client mode, to send similar data, being able to see the responses your server sends may give a clue as to why everything stops.

Re: [twsocket] Close connection (destroy) idle clients
Could use ThrdServer example, the problem was solved with WSocketServer1.Banner: =''; now I can not receive data, by setting longer just LINEMODE = FALSE, and after a few connections, does not enter the event OnDataAvailable when LINEMODE = TRUE event OnDataAvailable is never triggered OnDataAvailable is identical in all ICS components, does not matter which client or server demos you look at. You have not told us what protocol your POS terminals are using, specifically whether it is ASCII line oriented or binary packets, and LINEMODE=TRUE will only work with the former. In practice, I rarely use LINEMODE=true even for line oriented protocols, because sometimes those lines may be thousands of characters long and exceed the buffers. I usually use Receive or ReceiveFrom to accept data into a buffer, and then loop through the buffer character by character checking for line endings and other control characters and writing a simple string for further processing. The loop can check for long lines and have a timeout if data stops half way through a line. For an example look at procedure TMagIpLog.SocketDataAvailable in the component I recommended you use for testing yesterday, you are simply trying to reinvent stuff that others have done already.

Re: [twsocket] Close connection (destroy) idle clients
Hello, I am using the example OverbyteIcsThrdSrvV3.dpr plus what happens is that the wind ClientDisconnect is called before processing the received data, and so the connection is lost I assume you have turned off the default banner that the server component sends upon answer (set Banner:='';), that will upset clients expecting a specific response. Have you tried the TMagIpLog demo? It is very simple, and very reliable. You can also try using a simple client OverbyteIcsCliDemo.dpr to connect to your server so you can see exactly what happens on connect. When writing server protocols, it's often useful to have a test client application to methodically test the commands you implement, with false or corrupted data for instance, which is hard to test with your 'real' client.

Re: [twsocket] Close connection (destroy) idle clients
Hello guys, I'm using the component connections TWSocket for various customers making and receiving requests, in some cases the client loses the connection to the server, TCP not necessarily know a connection is lost since there may be no packets sent for many hours. You normally implement inactivity timeouts to disconnect clients that don't respond. If you used the Socket Server as I suggested yesterday, much of this is automatic. You don't normally need to use threads in an ICS application, unless you are making long blocking calls, 500 clients without threads is common. You check SocketState property to see if a connection is closed. if ClientThread.ClientWSocket.OnSessionClosed then No idea what you are attempting to do here, this is an event handler setter, not a property.

Re: [twsocket] Need to Exclude Folder
I have an application for backup that works on LAN. All data is copied into a Folder and subfolders (please refer below pattern). Using MagFTP component I intend to syncronise the Local backup onto the FTP site (g:\Backups\*.*). My problem is that there is one folder that I need to exclude (g:\Backups\tempfiles\*.*). Is it possible without using the Single File Upload method ? TMagFtp has a string property IgnoreFileExt that allows you to specify a semicolon delimited list of file extensions that will be ignored, ie tmp;temp;bak. There is also a binary property SpecificFiles that allows a list of files to be downloaded or uploaded, the files names are a | delimited list passed in SrcFName. Beware I've not used this for a long time, can not recall why it was added. I suspect what you really need to exclude a small number of files from a large selection is a new event, somewhere after the calls to fMagFileCopy.SelectCopyFileList. This function compares the source and destination file directories and selects which will be transferred. You could check SrcFileList for any you don't want to copy, and deselect them by setting FrFileCopy := FCStateNone.

Re: [twsocket] MagFtp and SslContext
I do not have much knowledge about SSL but I presume SSL certificates are required if my client decides to use a FTPS site. No, it is not necessary for client software to check SSL certificates to use SSL connections, the data is still encrypted. Checking the certificate is an extra level of security to ensure the data is coming from the correct server. Certificate checking can be done, most of the code is there in TMagFtp, but there is an extra overhead for each connection, and more errors to handle if the certificate fails checks. Server software always needs a SSL certificate.

Re: [twsocket] Resume in Magenta
In between I unplugged the Server LAN wire so as to break the Transfer. When I said to upload again it does not Resume. As you can see from the logs, all the commands to correctly resume the upload are being sent, but the control connection appears to drop at that point: !! FTP Error: FTP component not ready Without any time stamps in the log, it's not possible to see if this was instant or after a timeout. There is a property FailRepeat that I usually set to three so a failed attempt retries twice more automatically in case of transient errors. For testing resume, you don't need to use massive files, you can slow down the transfer to 25K a second or something on your LAN so that you can halt the transfer part way through more easily: FTP.BandwidthLimit := bandwidth * KBYTE ; FTP.Options := Options + [ftpBandwidthControl] ; I've not specifically tested resume for a few years, I automatically FTP hundreds of files to and from my public server daily, but it all just works. If you can reproduce the problem with the TMagFtp v4 demo or DUN Manager beta v3.10, I'll look into it.

Re: [twsocket] Fwd: Date Time ?
I am using TSslFtpClient and and need the DateTime of remote files. From what I understand the only way is via the Dir command. If so how do I parse list ? Is there fixed format ? The DIR command is supported by all FTP servers, and can return numerous different listing formats, essentially the OS dir listing. In practice, you will find only UNIX or MS-DOS listings and you have to parse them. Not UNIX format does not have the file time for files older than one year. Better FTP servers also support the MLSD command which is a standardised format. Both these command list only the current directory, if you need sub-directories you have to keep changing directories and DIR or MLSD again. The ICS FTP server adds XCMLSD and XDMLSD which are similar to MLSD but provides recursive listings for sub-directories so will list hundreds of directories in a couple of seconds, which takes several minutes with the older commands. If you want a reliable working application use the high level FTP component TMagFtp from: http://www.magsys.co.uk/delphi/magxfer.asp which uses all the above listing techniques depending on what the server supports using a single command BuildDirList, or SelectCopyFileList is you only want to know which files are different to those on your local disk, ie when updating a web site.

And you added to OverbyteIcsIcmp.pas OverbyteIcsWSocket.pas. Yes, because you added a lot of IPv6 helper functions to WSocket and it was more sensible to make use of tested shared code than continue to use duplicated WSocket code in those two units and have to expand it considerably. Unless there's a cross-platform solution I do plan to added a ping using raw sockets that should be cross platform, I've got a lot of the code in my raw socket monitoring component, although it needs expanding for IPv6 packets.

Re: [twsocket] Simultaneous TPing request using multithread.
I need to build a network monitoring tool that will ping about a 1000 IP's on a regular basis, I plan to use Thread-Pool for this. I did a major rewrite of ICMP and Ping last month, including a new threaded ping component and a trace route demo that sends off lots of pings using threads. Unfortunately Arno decided it would not work on FireMonkey (about which probably very few care) and he removed it from SVN. Since I can not actually build the FireMonkey packages in XE3 which are undocumented, get too many silly errors, everything is on hold until I have sufficient spare time to try and reverse engineer his changes. I know there is an issue with doing simultaneous ICMP request because all the listening socket receive the reply and this create confusion. My older thread ping component has been sending dozens of simultaneous requests for 10 years without any issues.

Cool, I'll be able to test it a bit next weekend. No problem, just need to test it with XE3 and 64-bit, and find out why the sample no longer runs on XP. Although we've always been used to a blocking ping, it transpires Microsoft added async ping using a callback with Windows 2000, which I have implemented. Unfortunately it does not seem to actually work, the return code says ERROR_IO_PENDING but the callback never happens. Googling I've not found a single example in any language using the callback or anyone that has ever made it work. But I have added my threaded ping to ICS, which is how the trace route works. I'm also trying to get another SIXXS tunnel for my public server (until the firmware in my firewall gets IPv6 support) so I can make ICS servers available on IPv6.

Re: [twsocket] ...SMTPClient
I need to add up to 200,000 names to the ToList, which could be about 4,000,000 characters. Can T...SMTPCli handle this quantity? Most ISPs have blocks on their SMTP relay servers to prevent mass mailing by spammers, typically a few hundred or thousand messages a day, after which your account may be blocked. There may also be a limit of 25 to 100 recipients per message. So unless you are sending using your own SMTP relay server, sending 200,000 emails is unlikely to be an issue, you won't be sending any atall. I'm sure there is a limit in the SMTP specs for recipients, but you are more likely to hit an ISP limit first. Also, you may find emails send using BCC are more likely to be detected as spam, it's much better to individually address emails, although still within your ISP limits. This is how my own mass mailer works, written with ICS 15 years ago and hardly touched since.

Re: [twsocket] Binary download problem solving
There is an issue, which is not directly related to ICS, but since ICS provides a webserver that may help in solving it, I'd like to hear some advices from you. The problem happens with Chrome and Android's browsers while downloading binary files from a webserver. You may read description of the bug at http://code.google.com/p/chromium/issues/detail?id=104331 This is a long one year old thread, during which time no-one has found a solution. I only skimmed the thread, but it seems a badly behaved download manager is involved and messing with server headings is an attempt to make Chrome download something in the hope it's better. It really looks like a Goggle issue, let them fix it. Is this problem reproducible with Chrome under Windows, or is it simply non-Windows platforms?

Re: [twsocket] FTP Client - Large files

Re: [twsocket] FTP Client - Large files
Filezilla seems to handle with a no response timeout, followed by a query, some times even a reconnect, to check if the file is effectively there, and with the correct size. Similar features are the benefit of using the TMagFtp high level component. It also checks the correct sized file has been uploaded, will do a CRC32 or MD5 check to ensure it's not been corrupted, and will repeat the upload if necessary. But I'm not aware TMagFtp specifically handles a missing response, unless by accident! Most servers will timeout the control connection anyway once activity ceases that could cause TMagFtp to close everything down. Without having seen any proper FTP logs for this bad server, this is all conjecture.

Re: [twsocket] FTP Client - Large files
My code is basically a state machine. In the FtpRequestDone event, it decides what to do next. I used a similar state machine in another application, but prefer the sync calls for complex applications, and then use a thread per transfer. TMagFtp has been tested with 200 simultaneous downloads. You do have to be very careful not to call the message pump from within RequestDone or things can get very confused. Do not call any sync methods that will call the message pump, ie only call CwdAsync not Cwd. So the question is: What are you doing in your demo that is different. Using sync methods with WaitUntilReady which loops calling the message pump until State is ftpReady or ftpInternalReady, rather than expecting the FtpRequestDone event to be called. It is possible there is a strange component bug and the state is being changed without FtpRequestDone being called. My component does not use FtpRequestDone atall. You could try checking the StateChange event as well to see if that is called when your transfer finishes, or just check the State property in the fail safe timer I assume you have running to handle errors and stop the application waiting for days. Wireshark shows you are doing ALLO Not sure why you using Wireshark, the FTP component has all the events you need to log the FTP protocol, even without the logger component.

Re: [twsocket] FTP Client - Large files
My code just does putAsync and waits for the ftpPutAsync event. I don't know exactly how the xferdemo3w does it You have all the source code for TMagFtp, so you can easily check. There are probably two main differences: 1 - TMagFtp uses the sync FTP calls and WaitUntilReady, so check that function for special handling. 2 - The component has been developed and tested over several years and so is very solid with a lot of special error handling to make it very stable. One caution, xferdemo3w uses a 'special' widestring version of ICS v8 that works with Delphi 2007, to use the unchanged ICS version test against xferdemo3 which is pure ICS.

It's not clear how to switch to the mode that mime-types to be read from Windows Registry by default? You drop TMimeTypesList onto the form and attach it to all your server instances, or add it in code. Look at the OverbyteIcsWebServ demo to see how it's attached, and OverbyteIcsMimeDemo allows you to see what MIME types it picks up from the registry and how to modify the list. The registry does include: .svg=image/svg+xml but not application/javascript, although it is in the mime.types files used as an alternative. Or you can add it using the AddContentType method.

Re: [twsocket] Minor omission fixed for improved Web-server operation
I think loading hundreds of types from Registry when 'js' is missing in the default list is overkill, because most of them are not Internet-involved. Everyone has different requirements, TMimeTypeList is designed to support email as well where many different file types may get sent as attachments. The lack of application/javascript, must look at IIS to see how it handles such files. now I'd propose to revise TMimeTypeList.Create, where the default types are registered, and populate it with the omitted types, which should be there by default, imho.

The 'app interface' could be your problem, if you are calling the main thread using synchronise to update a GUI dynamically. Ensure you don't call synchronise more than once every few (configurable) seconds which is quite adequate to keep someone watching happy that it has not died. ICS will usually handle a few hundred async component instances quite happily in the same thread all processing at the same time. In your case, once you have written the code to support more than one instance and more than one thread, just make it totally configurable so you can try 10 threads with 400 instance, or 40 threads with 100 instance, etc, so you can easily experiment.

Re: [twsocket] Optimal number of TWSocket per thread
I perform some tests but cannot send fasten than 200 megabit/sec. Which is pretty good performance, presumably you need more because this is running on a hosted server with gigabyte connectivity?

My question is: why message data send line-by-line instead of larger portions ? But that does not mean SmtpCli can not send multiple MIME lines at a time using Send or something, reducing the number of function calls. It was probably written to send a line at time at a time when were all using slow modems to communicate with each other. It is probably a relatively simple change to SmtpCli, but finding the time to look at it is difficult for all of us. Is it something you can change yourself?

But testing of IPv6 itself is limited due to issues such as very few firewalls and routers supporting IPv6. I have a public IPv6 address allocation (2a00:1940:0001:0002::/64), but can not use it yet. I've done limited testing with FTP and HTTP on my internal network, but none yet on the public internet until Sonicwall offers IPv6 support for my firewalls (which means buying new hardware). 3. If I need to switch to ICS V8 - Any breaking changes between ICS V7 and V8? - Any major changes necessary in my legacy code if I just want to keep IP V4? You need to check readme8.txt for details on updating, all the directories have changed and some minor functions gone. There are no program changes needed to support IPv4, but you will need changes for IPv6. 4. Going from IP V4 to V6 - Any documentation/examples/tutorials available No documentation yet, I am planning to write a getting started guide for IPv6, but have not had time yet. You'll need to look at the IPv6 implementations in the HTTP and FTP server components to see how to implement IPv6 in your own applications, and the new demos OverbyteIcsTcpSrvIPv6. Note that IPv6 is not yet supported by all the components, ping in particular is missing, which I plan to do next month.

Re: [twsocket] TiggerSessionClosed...
It is on shutdown so I am not worried. The issue is FastMM reports the leak each time I quit and that is a pain. It is probably a false report. I use the ICS web server which uses SocketServer, and there are no memory leaks after over 100,000 connections.

Re: [twsocket] TiggerSessionClosed...
It is probably a false report...
MadExcept also reports it as a memory leak.
So after say 10,000 connections, how much extra memory is your
application using than when it started? The VCL often leaks small
amounts of memory, but unless is cumulative it really does not matter.
Use something like:
var
ProcMem: TProcessMemoryCounters;
begin
GetProcessMemoryInfo (GetCurrentProcess, @ProcMem,
SizeOf(ProcMem)) ;
with ProcMem do
begin
AddLogLine ('Program Memory Usage: Working Set ' +
IntToKbyte (WorkingSetSize) + ', Paged Pool ' +
IntToKbyte (QuotaPagedPoolUsage) +
', Non Paged Pool ' + IntToKbyte (QuotaNonPagedPoolUsage)) ;
end ;
end;
You can also log program handle usage and global memory and handle usage
to find serious problems.

Re: [twsocket] deflate for OverbyteIcsHttpCCodZLib
Tested with this website http://myanimelist.net/malappinfo.php If I enable content encoding, then the data received isn't compressed unless I add deflate. Whether the site compresses the data is not the issue, it's whether the ICS component can decompress anything with the change you proposed. And my testing shows not. I suspect I know the reason, if a compression type of 'gzip, deflate' is added, it expects exactly that string to be returned, the component does not parse the separate words. Your test site also does not use deflate, testing with the ICS browser demo gives: [0] GET /malappinfo.php HTTP/1.1 [0] Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* [0] Connection: Keep-Alive [0] Accept-Encoding: gzip, deflate [0] HTTP/1.1 200 OK [0] Date: Mon, 08 Oct 2012 08:41:14 GMT [0] Server: Apache/2 [0] X-Powered-By: PHP/5.1.6 [0] Vary: Accept-Encoding [0] Content-Encoding: gzip [0] X-Served-By: app2v-mal.ao.prd.lax [0] Content-Length: 76 so it returns gzip not deflate, and ICS fails to decode the XML.

Re: [twsocket] deflate for OverbyteIcsHttpCCodZLib
Tested with this website http://myanimelist.net/malappinfo.php If I enable content encoding, then the data received isn't compressed unless I add deflate. Found and fixed the bug in OverbyteIcsHttpContCod, it was parsing multiple encodings in the response header rather than the request header. Your test site still ignores deflate, but decodes correctly with gzip, maybe they reconfigured the server since you reported this issue in early 2011. But deflate does work with the ICS web server, much to my surprise since I added that feature a few years ago.

Re: [twsocket] deflate for OverbyteIcsHttpCCodZLib
Please add the following modification to OverbyteIcsHttpCCodZLib, I was sad to see it's not yet included in the last V8 : class function THttpCCodzlib.GetCoding: String; begin Result := 'gzip, deflate'; end; Have you actually tested this? If I make what seems to be a simple change, all pages with gzip decoding fail to decode and display. I've looked briefly to see what is failing, but the coding of THttpContCodHandler is convoluted and the reason is not obvious. This is why we are careful about making such changes, and ensure they are tested thoroughly.

Re: [twsocket] FTP Error Code and Messages
Where can I get a list of all the possible error code and error messages for the methods in the FTP component. Sorry, there is no such published list.

Re: [twsocket] How to save attachments - MimeDemo
I am using Delphi 7 and learning the
component OverbyteIcsMimeDemo, I am writing a program to read my
messages and save them as text files and save any attachments as
separate files. I seem to have grasped the export of text data
however any attempt at save the attachments fails and I simply do
not understand
how to for example identify a pdf attachment and save it to disk
or in fact any attachment.
Run OverbyteIcsMimeDemo, specify mime-demo3.txt and click 'Decode File
Extended'. This will decode all MIME parts and load them into an array
MimeDecodeEx.PartInfos, with one record for each part, reported similarly
to this (edited):
Part 6, Content: image/jpeg, Size: 4902, Name: wt_logo_210x47.jpg,
FileName: , Encoding: base64, Charset: , ApplType: , Content Id:
453445709@24012008-0DED
Part 7, Content: image/gif, Size: 4979, Name: Watch-the-film1.gif,
FileName: , Encoding: base64, Charset: , ApplType: , Content Id:
453445709@24012008-0DF4
Part 10, Content: application/vnd.ms-excel, Size: 75776, Name: D10.xls,
FileName: D10.xls, Encoding: base64, Charset: , ApplType: vnd.ms-excel,
Content Id:
Your application needs to loop through the different PartInfos records in
the array, similarly to DecodeFileExButtonClick, checking PContentType
which contains the MIME type for each attachment, ie image/jpeg,
application/vnd.ms-excel or application/pdf for Acrobat files. Sometimes
the PName and/or PFileName will have a complete file name with file
extension, sometimes they will be blank.
You can use the function ContentTypeGetExtn to get the Windows defined
file extension for any MIME type if you want to build your own file name.
I guess the one thing missing from the demo is how to save the content,
which is patiently waiting in PartStream, so use the SaveToFile method:
try
MimeDecodeEx.PartInfos [I].PartStream.SaveToFile (fname) ;
except
Log('!! Failed to Save Attachment) ;
end ;
Note the V8 OverbyteIcsMimeDemo dfm file seems to have got corrupted and
is missing several new buttons added to test TMimeTypesList, I'll fix it
later today.

Re: [twsocket] FTPCli in thread
*Subject:* [twsocket] FTPCli in thread *From:* Fredrik Bergström fredrik...@ko2000.nu *To:* twsocket@elists.org *Date:* Mon, 17 Sep 2012 19:41:01 +0200 Hi, I started writing an message to this list about an timeout-issue we have been having, but I think it may be better for me to first ask for some guidance on how to run OverbyteIcsFtpCli properly from a thread. I know we should have some kind of message pump running in the thread, but would it be ok to have something like this? TMagFtp from: http://www.magsys.co.uk/delphi/magxfer.asp uses FtpCli in a thread, and has a demo program to run 200 FTP sessions simultaneously. But it uses sync methods, since the thread is dedicated to FTP and does not have a form to keep responsive. The most important issue is to create the FTP component in the Execute method of the thread so the message window has the correct context, and set Multithreaded to true so the ICS message pump is used while waiting for sync methods to complete. Nothing more complicated than that.

Re: [twsocket] FTPclient Error 426
When I copy the exe to another computer Window's XP every FTP server (8 different servers) we connect to gives an ErrCode = 426 with a message Operation Aborted. When FTP fails to run on a specific computer, it's nearly always configuration of that computer, usually a firewall or router stopping it working. Sometimes changing to Passive mode can help.

Re: [twsocket] FTPclient Error 426
I really like the component. One question is there more detailed help then the one online. Sorry, it has always been hard to find volunteers to document the ICS library, and in particular keep it updated for the constant changes we make. The developers all contribute their efforts free, and there is only so much time we can spend. As I said earlier today, you can look at the code in my high level TMagFtp component from: http://www.magsys.co.uk/delphi/magxfer.asp which makes FTP very easy to use, and is extensively tested over many years.

Re: [twsocket] FTPCli in thread
We are running this code for testing, as it shows the issue better: (Code has been stripped of error handling, etc.) I don't see anything wrong with your code sample, but you would be better using the tried and tested code from the WaitUntilReady function which duplicates what you are trying to do, but tests the State property to see when something is finished. Or just use the Dir sync function which calls WaitUntilReady. Sometimes TCP/IP does not behave as you expect when connections don't close properly, which seems to be your problem, which is why TMagFtp has the ability to repeat functions on failure.

Re: [twsocket] TSslSmtpCli won't complete TLS on port 25
I updated my AV software and the problem disappeared! Looking back, it may have started after the last AV update. Excellent, although I'm surprised anti-virus software is monitoring port 25 for outgoing email, and worse corrupting it. What make? I've had AV software corrupt FTP transfers in the past, sometimes accidentally, sometimes deliberately. The most annoying was my attempt to download a 6 gig Virtual Machine image which my hardware firewall stopped at 4 gigs when it found a development tool many AV packages consider a hacking tool. My FTP application kept repeating the download for 12 hours until I stopped it manually.

Re: [twsocket] TSslSmtpCli won't complete TLS on port 25
Here's the problem, there's nothing more received but a connection close after around 10 seconds? Ok, now we know, how do I fix it? I have no idea. This is unlikely to be specifically an ICS issue since there is no problem on ports other than 25, you need to find out why no further data is being received. It could be firewall/anti-spam software or appliances, a router, your ISP, etc. Does it fail on multiple PCs, with different internet connections and ISPs? Sorry we can not be more specific, but until an issue such as this can be reliably reproduced, it can not fixed. The only odd thing I've seen is you are using OpenSSL 1.0.0d, whereas I still use v0.9.8r which has a much longer stable history.

Re: [twsocket] THTTPserver...
I need to log the IP address of the client when it connects to the server. Look at the Web Application Server sample, OverbyteIcsWebAppServerMain.pas, which is similar to the main web server. It shows how to write W3C format log file from the AfterAnswer event, including how much data was sent. If you need to check the IP before processing the request, to blacklist it or display the IP in a response, use the BeforeProcessRequest event. In both case use Client.GetPeerAddr to get the remote IP.

Re: [twsocket] TSslSmtpCli won't complete TLS on port 25
I'm having a problem with TSslSmtpCli. It won't complete a TLS connection on port 25. This happens regardless of the server. How many different SMTP servers? I use STARTTLS with smtp.gmail.com on port 25 without any problems, try it. If it fails, it's probably your ISP doing strange things with port 25, like redirecting it their own SMTP server that does not support SSL.

Re: [twsocket] Problem with lost TCP IP messages
With a sniffer I can see that all 8 messages are coming from the remote device, but twsocket misses some. Sockets send a stream of data, which is error corrected to ensure nothing is corrupted or missing. If you are missing bits of that stream, the error must be in the way you removing data from the received stream, in the SocketDataAvailable event using ReceiveFrom or Receive. I've got applications sending data to each other each second for weeks at a time, with no lost data.

Re: [twsocket] Ping doesn�t work for 64 bit
Hello, I wonder if there is any solution to the Ping component, it is not working under Win64. I´m getting the error: _General Failure_, compiled with Delphi XE2 (icsv8w-140712) under Win 7 64bit. I have reproduced your ping problem on Win7 64-bit. Looking at MSDN, it appears a slightly different IP_OPTION_INFORMATION and ICMP_ECHO_REPLY structures are used for IcmpSendEcho function on 64-bit platforms, so icmp.pas needs updating. Also note we are using icmp.dll which since Windows XP has been a stub calling the real DLL for iphlpapi.dll, so that really needs changing as well. We can then support IPv6 ping as well, which needs adding.

Next I try and do a directory listing on this folder. The response indicates no error, but the stream is of zero size. LIST only returns file in the current directory, so unless there are files in Test1/abc it will return a blank directory. If you want to list all files in sub-directories you have to traverse the directory free listing each directory and combine all the results, or use an FTP that lists all sub-directories in a single command, ie the ICS FTP server. You can try my File Transfer Components which are high level FTP and HTTP components using ICS that will list sub-directories and copy all the files with a single command. http://www.magsys.co.uk/delphi/magxfer.asp Angus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
