evlncrn8 Posted August 20, 2018 Posted August 20, 2018 (edited) ah well, that i didnt think about, or the complexities of having to read documentation thats typically not in native language, i stand by the rest of what i wrote though Edited August 20, 2018 by evlncrn8
kao Posted August 20, 2018 Posted August 20, 2018 I promised not to post anymore but since flamewar got started by my post, I think I should also finish it. Try to read your topics like someone else would. Then maybe you'll understand my point of view. Here's how most of your topics look like from where I stand: 1) You ask a question. You don't do it the smart way. You don't tell what is the problem you're trying to solve. Instead, you jump to what you think is a right solution and ask how to implement that. Want an example? See your topic about resource structures. You started by asking how to parse all the structures manually and only after 10-20-whatever posts it turned out you can use standard Windows APIs. Same about HTTP downloads, you started by implementing all HTTP protocol manually over winsock, ended up with using winhttp/urlmon/whatever APIs. And all this time members of this board spend their time to find solutions for you - which turn out to be overly complicated and unnecessary; 2) When someone give you a perfectly valid suggestion of what you could do, you find ten excuses why you will not take that advice and do it another way. Fine by me, but then why did you ask for help in the first place? I spent quite a lot of time researching answers to that question, trying to find the best answer for you. And that time seems to be wasted. 3) Then you do that thing "your way". It - quite predictably - doesn't work. You complain. A lot. About things you can't change anyway. Just search your topics for phrases like "this sucks" or "thats BS" or similar. That's not constructive or helping in any way, just annoying. 4) Then you ask for an example code in MASM. Because you claim it's the only language you can understand. Nobody uses complex libraries with ASM these days, so there is almost no code to be found. So, members of this board do the next best thing - find you examples in the different language, usually C. You complain. A lot. Because you can't compile the example. Because downloading free Visual Studio Community Edition and free Microsoft SDKs is such a chore.. Repeat the step few times. 5) Finally you get the example code working. You quickly write your own code in ASM. It doesn't work. Instead of reading source code/debugging the compiled example and getting an understanding why it works and your code doesn't, you complain that the XYZ library sucks, the documentation is useless and everything is crap. The solution is somewhere in the example source code, documentation or found with less than 5 Google searches. Repeat the step until the end of the topic. Sure, these are your topics and you can do whatever you want. But I just don't want to be any part of that anymore. Now let us all get back to reversing/coding/whatever else we were doing before the interruption... Peace!
LCF-AT Posted August 21, 2018 Author Posted August 21, 2018 Hi, didnt I told you that the docs and whole client example code wasnt helpfully for me build a working example?I think so and thats also the problem I tried to solve.If I have any questions then I use this forum (if I cant handle it by myself yet) to get some helpfully answers.I dont have any problem with that.Some people need some help to any theme and some give some help if they can with the right matching context which can be simple till complex.I dont wanna hear answers like read the docs / manual if I told already that I did and have problems with that.Its nice to hear that its for you no problem to read that "Fabulous" manual like a shopping list where I can just say congratulations to you but I cant you know.Thats the diffrent.Some people can and some not or not so good.I know that you are one of the smartest person who know almost everything about PC inside / outside stuff kao,(thats the reason I called you super brain [of course not in a pathetic way as evlncrn8 thought]) because for you its no problem and maybe you work with PC stuff 24/7 and I do not.I mostly try also to ask pretty simple in the hope that most do also understand what I mean and to get some simple answers back in return. Yes I like to use phrases like BS / this sucks or something like that just because I am a human with emotions and I dont hide them also if they are not productive to fix any problem.I am not a robot or android like Data. Some other questions are pretty simple to understand,so if anyone wanna help then you can read it in the answer/s between the lines.In your case I can mostly just read some kind of contempt not just since yesterday what makes me angry.Just my opinion of course. Anyway,so nobody told or forced you to be part of my "stupid asking topic/s" but if you already know what comes out at the end then you should better not start the process. greetz
evlncrn8 Posted August 21, 2018 Posted August 21, 2018 (edited) can you get visual studio, and install it and the libs so that wont be a problem in the future though ? cos, i do get the 'do it in asm / pure language / whatnot', and i too was once like you a coding purist, then x64 came along and changed things a lot.. for small projects managing some asm and porting it to x64 asm might be relatively easy, but there are so many overheads its a lot easier to do most of the core in c/c++, and if you must code a function / portion for speed do it in asm sure, but just that bit... but honestly, the compilers these days are pretty damn good and could probably optimise the hell out of c code potentially better than any hand written asm you might make.. and for that reason im mostly doing pid in c/c++ now, with just the main 'engine' routines in asm (if they are needed to be in asm)... the days of optimising for size are long gone, look how bloated the os is even.. let alone crap like .net at 20mb+ for the framework alone same could be argued for speed, the processors now are considerably faster than in the old 80386 days... a lot has progressed on / modernised, perhaps your way of thinking / coding should too, as the os you're using is pretty much all (except for specific .. minimal components) c...

LCF-AT Posted August 21, 2018 Author Posted August 21, 2018 Hi again, hhmm.Thank so far.I will see whether I try to install that visual studio and trying to use it anyhow and see whether I can do something with that (not sure so I am no expert on this field you know).Yes I see almost everything is written in c/c++ these days. I still have questions about that websocket issues I have.I tried to write another new code with the example websocket address I did post before using nopoll functions.My new code seem to get a connection to the server but the only thing I get from there is a PING string.If I check the connection in Opera browser / websocket tab / frames then I see what the browser did send and received.There I can also see a PING message which was answered with a PONG message by browser.Also other messages I can see there.My question is what I need to send and whether I have to send something or some specific strings first etc?On internet I found something about heatbeat = server sends a PING to check whether client (me) is still alive and is waiting for a answer from me = I send a PONG.Of course I still dont understand the whole process of getting / sending datas. My test code is this so far...without sending any string/s PONG etc. W2 proc hwnd:DWORD local ctx:DWORD local conn:DWORD local msg:DWORD local opts:DWORD nop nop nop invoke nopoll_ctx_new mov ctx, eax invoke nopoll_conn_opts_new mov opts, eax invoke nopoll_conn_opts_ssl_peer_verify,opts,nopoll_false invoke nopoll_conn_tls_new,ctx,opts,chr$("sapi-ws-1x03.vaughnsoft.net"),chr$("443"),0,0,0,0 mov conn, eax invoke nopoll_conn_is_ok,conn .if eax == nopoll_false invoke MessageBox,hwnd,chr$("nopoll_conn_is_ok 1 - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .endif @@: invoke nopoll_conn_wait_until_connection_ready,conn,5 .if eax == nopoll_false invoke GetLastError .if eax != WSAEWOULDBLOCK invoke MessageBox,hwnd,chr$("nopoll_conn_wait_until_connection_ready - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .endif invoke nopoll_sleep,10000 jmp @B .endif xor edi,edi .while edi == 0h invoke nopoll_conn_is_ready,conn mov edi, eax .if eax == nopoll_false invoke nopoll_conn_is_ok,conn .if eax == nopoll_false invoke MessageBox,hwnd,chr$("nopoll_conn_is_ok 2 - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .else invoke nopoll_sleep,10000 .endif .endif .endw invoke nopoll_conn_is_tls_on,conn .if eax == nopoll_false invoke MessageBox,hwnd,chr$("nopoll_conn_is_tls_on - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .endif @@: xor edi,edi .while edi == 0h invoke nopoll_conn_get_msg,conn mov edi, eax mov msg, eax .if edi != nopoll_false .break .endif invoke nopoll_conn_is_ok,conn .if eax == nopoll_false invoke MessageBox,hwnd,chr$("nopoll_conn_is_ok 3 - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .endif invoke nopoll_sleep,10000 .endw invoke nopoll_msg_get_payload,msg .if eax == nopoll_false invoke MessageBox,hwnd,chr$("nopoll_msg_get_payload - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .else mov esi, eax invoke MessageBox,hwnd,esi,chr$("Answer of Server!"),MB_ICONINFORMATION jmp @B .endif invoke MessageBox,hwnd,chr$("Finished!"),chr$("Info!"),MB_ICONINFORMATION mov eax, nopoll_true ret Just a test code to see whether and what I get from server / payload message.In this case only one time PING and after a while the connection is no more OK 3 and thats all so far.Has anyone some clue how the exchange should be? greetz
evlncrn8 Posted August 21, 2018 Posted August 21, 2018 sounds like the heartbeat in irc.. the ping pong.. basically you'll have to handle normal messages and 'special' messages (like not replying to the ping will most likely result in a disconnection from the server within a reasonably short time period), all of this should be in the respective rfc documentation for the protocol though https://tools.ietf.org/html/rfc6455#section-1.3 page 27 or so is where the fun begins, and page 36 or so is the ping / pong stuff, basically u have to respond to the ping with the pong and the 'extra data' the ping sent you.. this is essentially the heartbeat / keep alive... 1
LCF-AT Posted August 21, 2018 Author Posted August 21, 2018 Hi, I did read that rfc about websockets already but its of course not easy to understand (as always I know).I just only get that one PING as response what I also get if I call the site normaly.Below 2 pics of Opera at websocket traffic starting with first one.Green is sending and red receiving.The PING comes later not at first.. I also tried to send that first string MVN LOAD3 #vl-charliefreak but I also get a while nothing and then just PING.Other datas are not comming in. @ Teddy How many times you wanna send that manual link? Its not much getting better to find a propper solution. greetz
LCF-AT Posted August 23, 2018 Author Posted August 23, 2018 Hi again, I still dont get it work yet.Now I tried to use any other websocket address and found something here where you can test in browser... https://www.websocket.org/echo.html ...I tried to use this websocket address with nopoll functions to send / receive something but it fails already when I check whether the connection is OK or Ready (nopoll_conn_is_ok).No idea why this now.The websocket address I get is this..."wss://echo.websocket.org/?encoding=text" using secure socket port 443. invoke nopoll_ctx_new mov ctx, eax invoke nopoll_conn_opts_new mov opts, eax invoke nopoll_conn_opts_ssl_peer_verify,opts,nopoll_false invoke nopoll_conn_tls_new,ctx,opts,chr$("echo.websocket.org"),chr$("443"),0,chr$('/?encoding=text'),0,chr$("https://www.websocket.org") mov conn, eax invoke nopoll_conn_is_ok,conn .if eax == nopoll_false invoke MessageBox,hwnd,chr$("nopoll_conn_is_ok 1 - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .endif invoke nopoll_conn_is_tls_on,conn .if eax == nopoll_false invoke MessageBox,hwnd,chr$("nopoll_conn_is_tls_on - fails!"),chr$("Problem!"),MB_ICONWARNING invoke nopoll_conn_close,conn invoke nopoll_ctx_unref,ctx mov eax, nopoll_false ret .endif ...it fails on nopoll_conn_is_ok function (before the function was successfully).Also if I check manually nopoll_conn_is_tls_on function = failed too.Can anyone see where the problem could be in this case?Would be nice if anyone could see or show what I am still doing wrong if possible.Thanks. greetz
deepzero Posted August 23, 2018 Posted August 23, 2018 (edited) Something went terribly wrong when you pasted the "https ://www.websock et.o r g" parameter, it includes several zero-width space Unicode characters. Insert a clean version - https://www.websocket.org and then it works for me. edit: seems the zero-width problem is on my end ... seems when copying from the browser it inserts invalid Unicode characters. wtf. Fun times... --- As for the ping-pong, the manual says: Quote 5.5.2. Ping The Ping frame contains an opcode of 0x9. A Ping frame MAY include "Application data". Upon receipt of a Ping frame, an endpoint MUST send a Pong frame in response, unless it already received a Close frame. It SHOULD respond with Pong frame as soon as is practical. Pong frames are discussed in Section 5.5.3. An endpoint MAY send a Ping frame any time after the connection is established and before the connection is closed. NOTE: A Ping frame may serve either as a keepalive or as a means to verify that the remote endpoint is still responsive. 5.5.3. Pong The Pong frame contains an opcode of 0xA. Section 5.5.2 details requirements that apply to both Ping and Pong frames. A Pong frame sent in response to a Ping frame must have identical "Application data" as found in the message body of the Ping frame being replied to. If an endpoint receives a Ping frame and has not yet sent Pong frame(s) in response to previous Ping frame(s), the endpoint MAY elect to send a Pong frame for only the most recently processed Ping frame. A Pong frame MAY be sent unsolicited. This serves as a unidirectional heartbeat. A response to an unsolicited Pong frame is not expected. Have you tried sending back the Pong opcode of 0xA?

LCF-AT Posted August 23, 2018 Author Posted August 23, 2018 Hi, the copy / paste issue to get wrong values is a problem on this forum since a while already.If I copy some code / text from here and paste it into txt file or WinASM then I also see that problem to get spaces or ? sings inside.I removed them.In my code it looks clean same in the code I did post before.Why its working for you?Did you test same code as I did post or anything else? Yes I tried also to send a PONG 4 byte string back after I got a PING 4 byte string but thats all.Just get only PING string after few seconds and nothing else will send to me.In browser I see PONG string with 6 bytes maybe it used crlf. Here I found something of PING issue..if I check the OPCODE after PING I get opcode 1 using nopoll_msg_opcode. https://github.com/ASPLes/nopoll/issues/5 Till now I just get PING string using that one wss address and for the echo.websocket.org address it fails before already as I did post before.I dont get anything working yet. greetz
deepzero Posted August 23, 2018 Posted August 23, 2018 Dont think that bug is related, and of course I mislead you - that ping/pong stuff is ofc supposed to be handled by the library. I am not sure what kind of ping messages you are receiving though, it seems the vagnsoft endpoint has blacklisted my ip .. or at least I cant connect to it. How do you connect to it via browser? I'll look at it again this WE. Good night. 1
LCF-AT Posted August 23, 2018 Author Posted August 23, 2018 (edited) Hi, I think too that this ping / pong is handled by the library already.I also dont see any ping / pong code in the whole client code example of nopoll. Maybe the vagnsoft server address isnt used (103 / 104 / 105) that you got not connected etc.If you visit the main page then you can see which is used in webconsole or if you use FF with AddOn Websocket Detector then you can copy the address directly from bar icon if it pop ups if websocket was found. In browser (https://websocket.org/echo.html) then you see the location field already filled.Press connect and then send any text.In the log window you see what you did send and received = same.So its sending same back.In browser console of Opera / Chrome you see this... greetz Edited August 23, 2018 by LCF-AT http to https in link
LCF-AT Posted August 24, 2018 Author Posted August 24, 2018 Hi again, short info: Yesterday I did post the link to websocket.org with http instead of https.On the picture above you can also see on the ws:// address in location field that I was calling the site via http (didnt seen that).So you can use both,http and https and you see ws:// or wss://.Now I tried it again and this time I did check the websocket address but this time using port 80 for http / ws and used the functions for this and here its working so far.I can connect and connection has status OK and is also ready.Then I did send some text and right after I am using nopoll_conn_get_msg / nopoll_msg_get_payload and I get the same message I did send back.Same as in browser so far.So it means for this site using ws / http protocol = working (hey one success) but using https / wss / port 443 = not working using nopoll functions.In this case I get failed status back checking if connection is OK / Ready.In browser its working with https / wss / port 443 but not with nopoll functions yet.Not sure why this isnt working now.I also tried to use nopoll_conn_opts_set_ssl_protocol function instead with NOPOLL_METHOD_TLSV1_2 but also dont work.I am not sure whether I need to use nopoll_conn_opts_set_ssl_certs function using certificate files but I think normaly not,so I also dont need to use it if I use OpenSSL functions for https sites. greetz
LCF-AT Posted September 1, 2018 Author Posted September 1, 2018 Hi, I tried again a little to get it work.Some sites are working and for some its not working. Strange thing,for example the vaughnlive.tv sites.If I visit the main page then it does connect to websocket as I told before (getting PING messages).Now if I choose any channel there then it starts a new websocket where I get also the chat traffic to see.The websocket address is like this.. chat-ws-1x07.vaughnsoft.net/mvn ....now I tried to connect this address via nopoll (wss) but it dosent work as it did work for the other address sapi-ws-1x03.vaughnsoft.net from main site websocket. Example: invoke nopoll_ctx_new invoke nopoll_conn_opts_new invoke nopoll_conn_opts_ssl_peer_verify,opts,nopoll_false invoke nopoll_conn_tls_new,ctx,opts,chr$("chat-ws-1x07.vaughnsoft.net"),chr$("443"),0,chr$("/mvn"),0,0 invoke nopoll_conn_is_ok,conn invoke nopoll_conn_is_ready,conn ; <--- here it fails invoke nopoll_conn_is_ok,conn ; <--- fails too after invoke nopoll_ctx_new invoke nopoll_conn_opts_new invoke nopoll_conn_opts_ssl_peer_verify,opts,nopoll_false invoke nopoll_conn_tls_new,ctx,opts,chr$("sapi-ws-1x03.vaughnsoft.net"),chr$("443"),0,0,0,0 invoke nopoll_conn_is_ok,conn invoke nopoll_conn_is_ready,conn ; <--- Success invoke nopoll_conn_is_ok,conn ; <--- Success ...rest works Now I found another websocket site called https://websocketstest.com I did test this site too and its also working... invoke nopoll_ctx_new invoke nopoll_conn_opts_new invoke nopoll_conn_opts_ssl_peer_verify,opts,nopoll_false invoke nopoll_conn_tls_new,ctx,opts,chr$("websocketstest.com"),chr$("443"),0,chr$("/service"),0,0 invoke nopoll_conn_is_ok,conn invoke nopoll_conn_is_ready,conn ; <--- success invoke nopoll_conn_is_ok,conn ; <--- success ...rest success ...just wanna know why it does work for websocket addresses and for others not to get a successfully handshake.The echo.websocket.org sites using 443 port also dosent work as I told before too.Do these sites need some extra header informations or something like that? greetz
LCF-AT Posted January 18, 2019 Author Posted January 18, 2019 Hi guys, I am working again on this websocket stuff to get something working and to check how I need to use it right.So in some cases I get something working but still dont know what I need to send to websocket. Example: So in Opera browser I can see the traffic what was send & received.Here comes already my first question.From where do I know what I need to send first and after?I think there is no automatic way where I can say (connect to websocket X and exchange send / receive). There is one test websocket X where I get first the info connected and after that I can send a time request word only one time and now I can loop to read and get the time so long as I want.For other websockets I need to send something first and get something back and sending again / get results / update back etc also in a loop way.In another websockets is the traffic more complex and diffrent dynamic stuff is send I dont know yet and from where the browser does get / know it. So to make it short,the websocket in browser seems to work else than I use manually.I think its similar like if I do normal simple http/s request to any site and reading the pagesource instead to call the site in browser where all gets executed etc you know what I mean right.Does it mean that I am also in this case limited using just nopoll API function?I think so.In my case I always need to know what I have to send first / second / etc and or whether I need to send something first or not = no automatic handling hmm.Does it work for other websocket clients else like php etc?I am just asking you know. greetz
