kandi X-RAY | wssh Summary
wssh is a SSH to WebSockets Bridge that lets you invoke a remote shell using nothing but HTTP. The client connecting to wssh doesn’t need to speak the SSH protocol - rather, the SSH connection is terminated at the bridge level and the pty is wrapper through a thin layer of JSON and sent back to the client. This means you can implement a WSSH client in just a few lines of code, even for a web browser.

QUESTION
some webdev basic questions for a noob.
background: I have a javascript client that uses the websocket protocol, and a good old java server, which I'm perfectly able to interact with via telnet. I want them to be able to communicate to each other locally (passing strings would suffice).
For that, I definitely don't want to make deep changes in the client. I tried to adapt the server to websocket following this guide before that, and even passed the handshake but it got pretty messy.
So at this point I believe that the best way to deal with this would be to serve through a TCP->WebSocket proxy like websockify. If I got the explanation right, it would "wrap" the server's process, opening the "upgraded" connection in a new port. And the websocket client should be able to directly speak to the server through that port. But I've been trying to implement this with different approaches without success, therefore my questions:
- Is there a better way to deal with this problem? (that would explain google's sparseness, I can imagine this happens very often!)
- If "wrapping" is the best way and I got it right, how to implement it?
Implementation - edited: For the sake of testing, I've tried to build a simple echo server:
I'm running the very simple command line echo server suggested in this post:
ncat -l 2000 -k -c xargs -n1 echo. Talking to it viatelnet localhost 2000returns the desired echo. So far so good.I installed websockify using
apt-get,and run it as follows:websockify 2023: 2000, this should open the same server via a websocket connection on port 2023.At this point I'm still able to comunicate via
telnet localhost 2000, but I'm not having that much luck with port 2023. This is what I tried so far:- Downloaded the telsocket binary, and called
./telsocket -url ws://127.0.0.1:2023. Response:errrr dial tcp 127.0.0.1:2023: connection refused - Cloned wssh (a command line shell for websocket), which seems very promising. I was able to install it, but running
wssh -l localhost:2023returnsNameError: name 'PROTOCOL_SSLv3' is not defined. Apparently some problems withgevent(didn't look much further into that). - Tested the several examples in
websockify's repo, like wstelnet, or the ones in tests. All of them got me a code 400, message Invalid protocol selected.
- Downloaded the telsocket binary, and called
Follow-up - edited: Diving deeper into the websock.js and wstelnet.js files, I was able to get more specific results by issuing the following into the JS console:

- run the echo server
ncat -l 2000 -k -c 'xargs -n1 echo echoServer received' - in a separate process, run the proxy:
websockify 2023 :2000 clone the repo:
git clone https://github.com/novnc/websockify.git, and make the following changes to wstelnet.js:3.1 changing the line
ws.open(uri)tows.open(uri, "binary")allowed to overcome the code 400 problem.3.2 in the definition of do_recv (this is a permalink), add the following line after the initial
varstatement:arr = Array.from(arr);this is a conversion to Array since Uint8Array didn't apparently support theshiftmethod.open wstelnet.html with firefox, select Host: localhost, Port: 2023, no encryption, press Connect and type into the black field.
The screen should reply with echoServer received: . hurray!
QUESTION
I need help as I'm fairly new to VBA. My mission is to filter a master workbook to send all filtered results to their respective recipients which will be located in a workbook(the recipients and body of the email). I have over 50 emails to send to over 50 different recipients and am in need of help. The attachment i send also shouldn't be an excel attachment but rather a copy & paste in table format.
So far, the code below:

Answered 2019-Dec-08 at 21:18I would approach it one of two ways, convert the range to an HTML table and insert that into the email or use SendKeys '^c', true and then SendKeys '^v', true. My preference is the first option and here is the code:
QUESTION
I'm creating Quarto, the board game. It's essentially advanced connect 4.
Each piece has four distinguishing features (WHITE VS BLACK | TALL VS SHORT | SQUARE VS CIRCLE | SOLID VS HOLLOW). If you get four of any of those features in a row, you win.
At the moment, I am current trying to write a function to check for a win. However, it is on track to be O(n^4), and I think I can improve this depending on how I structure my code.
Currently, I have this:
