I've been headdesking for half an hour trying to figure out why the heck a div border would show on chrome, a but not on FF. A border that is actually a png transparent background image. And the top, bottom and left borders would show, but not the right one. Turns out FF zoom was only slightly zoomed out

somequixotic

instead of bourne shell, journe shell

Journeyman Geek

15:05

lol

Bob

argh. I'm about ready to pull my hair out. damn it, netcat

anyone here know the http protocol well?

specifically, is there anything I can send to signal the end of a response?

just spent an afternoon reading HTTP 1.0 docs. nothing. apparently, closing the connection is enough, but then Firefox (and Chrome, and IE) complains about a reset connection D:

somequixotic

@Bob two newlines at the end of the http body is sufficient to signify "end of request", I believe

Bob

@somequixotic I thought that was end of headers?

I'll try that, though. Thanks.

That Brazilian Guy

@Bob Sacrifice a black goat to The Elders of The Internet. I think I read it in some RFC.

Bob

@ThatBrazilianGuy I'd rather not go to such an extent yet, thanks :P

Journeyman Geek

15:12

lol

Bob

@somequixotic Nope.

With the addition of a content type header, it'll briefly flicker and display the body before displaying the connection reset error.

Weirdly enough, rekong seems to work :S

botlike typing detected

user72446

hehe

That Brazilian Guy

CatBot?

Journeyman Geek

catbot like typing detected

somequixotic

actually it wouldn't be that hard to write a program that emulates cat behavior; cats aren't sentient, merely sapient, so as far as computability, they're a lot closer to being computable than true self-aware sentience

what you'd really need are just a lot of sensors that respond to the environment -- cats respond to their environment in reasonably predictable ways -- once you have enough sensors for cat sense data (smell, sound, sight, touch), bam you have a cat

That Brazilian Guy

You are insane in a really cool way. I like you.

somequixotic

15:30

but sentience goes way beyond sense data because we're (usually) in control of how we respond to sensory inputs, so one human might stare blankly in response to a certain sensory input, while another human might pull out a gun, while another human might eat a banana

Journeyman Geek

@somequixotic: thats true of dogs too

don't forget, input isn't just for the moment

somequixotic

with cats it's just a matter of data collection -- collect enough data on their instinctual responses to certain sense inputs, and you can make a truly convincing artificial cat

Journeyman Geek

you also have a collection of past input

somequixotic

true, but the amount of influence that past input has on current responses is very limited in most animals, except for habit training, which can also be taught to computers

there's no cognition behind habit -- it's a function of the basal ganglia that simply hard-wires certain sensory inputs to certain instinctual responses, essentially a sort of "learned instinct"

Bob

Oh for-

It's got something to do with how netcat is closing the connection.

Fark.

That Brazilian Guy

@Bob I tried to: superuser.com/a/634821/165442

a lot of shell stuff with core utilities and so forth

Journeyman Geek

not only have I spent years using Linux distros but I spent two summer internships basically dedicated to mastering that kind of thing

Journeyman Geek

Bob

fml

I can't get it to work with named pipes, either

what is this crap

somequixotic

15:46

@Bob you named the pipe wrong -- name it something like "pleasebenicetome" and it might work

Bob

@somequixotic tried that

Journeyman Geek

lol

somequixotic

i wonder if it's because Chrome/FF/IE pass the Connection: Keep-Alive HTTP header expecting the connection to be left open

but when you close it, it's like, ":O ... that wasn't supposed to happen"

Bob

@somequixotic I'm replying with a HTTP/1.0

which didn't have keep alive

somequixotic

@Bob but the original request is HTTP/1.1?

Bob

15:47

@somequixotic Yes.

I was expecting the browsers to play nice and fall back to an older version.

somequixotic

what does the spec say about what browsers have to do when they request HTTP/1.1 and the server replies HTTP/1.0?

Bob

That's what they're supposed to do.

> Clients and servers SHOULD NOT assume that a persistent connection is maintained for HTTP versions less than 1.1 unless it is explicitly signaled. See section 19.6.2 for more information on backward compatibility with HTTP/1.0 clients.

Hm.

I might try sending a Connection: close

somequixotic

or you could just, you know, leave the connection open....

Bob

@somequixotic I have a single netcat instance running in a loop.

Also, that would mean I'd have to send a content-length

somequixotic

@Bob does netcat automatically close the TCP socket when you send EOF?

Bob

15:51

which would be quite annoying (say, restructure the whole thing)

@somequixotic well, I'm not using pipes at the moment

I'm using the -e option (run a script)

but, yes, it does close the socket

somequixotic

I think the way HTTP requests normally work is that you send EOF at the end of the request but leave the socket open; EOF is just another character to indicate "this is the end of this request"

traditionally, UNIXy things have interpreted EOF to mean "close the channel/socket/pipe/whatever"

Bob

Nope. Sending a Connection: close did nothing.

somequixotic

but you can actually, at a byte / wire protocol level, send an EOF and leave a socket open

Bob

@somequixotic Nope.

According to HTTP specs...

wait a sec

> When an Entity-Body is included with a message, the length of that body may be determined in one of two ways. If a Content-Length header field is present, its value in bytes represents the length of the Entity-Body. Otherwise, the body length is determined by the closing of the connection by the server.

That's for HTTP 1.0

John Cavil

@user247365 Hey there! You're pretty special, aren't you? :)

Bob

15:54

w3.org/Protocols/HTTP/1.0/spec.html#BodyLength

somequixotic

@Bob maybe you could implement the bare minimum for HTTP/1.1 ?

Bob

And for HTTP 1.1:

> 5.By the server closing the connection. (Closing the connection cannot be used to indicate the end of a request body, since that would leave no possibility for the server to send back a response.)

w3.org/Protocols/rfc2616/rfc2616-sec4.html

@somequixotic I think I'll just write my response to a file and then read that file...

and add a content length header

ffs

somequixotic

you don't need to do that, to get the content-length

Bob

Ok. That works.

But it needlessly complicates things.

@somequixotic Hm?

I guess I could store it in a variable.

somequixotic

at least in bash you can get the length of a string in a variable quite easily

don't know about POSIX bourne shell

or RA Journe shell

Bob

15:59

Problem is, I was writing the message as I went. To get a content length, I have to know what the full message is.

somequixotic

right...

Bob

That's... annoying.

I wonder how php's flush works.

> Flushes the write buffers of PHP and whatever backend PHP is using (CGI, a web server, etc). This attempts to push current output all the way to the browser with a few caveats.

to do that, it can't possible that means content-length can't possibly be used

somequixotic

just FYI, I think Content-Length: is still a very important HTTP header, particularly for downloads (MIME type application/octet-stream and so forth), because it gives file dialogs a progress %

Bob

Hm. Probably chunked transfer.

@somequixotic Of course.

But for a simple text-serving shell script, it's not entirely necessary.

HTTP specs say it's not necesary.

Of course, every major browser has to be an absolute bitch about it.

What the hell does "connection reset" even mean?

A closed connection is not an error state

It's supposed to happen

somequixotic

@Bob google "ECONNRESET"

Bob

16:02

@somequixotic Well, yes.

I already did that.

the problem is, that's not really an error.

Oh, wait.

somequixotic

it's a standard errno for when a TCP socket is closed during a read(), I believe... the browser has the option to say "oh ok, that's fine" or say "wut? I didn't expect this to happen.... let's tell the user!"

Bob

@somequixotic Except HTTP specs say it's perfectly normal for the connection to be closed at the end of a message body

Oh, this is interesting.

> It would appear that ECONNRESET means that the other side has closed the connection without reading outstanding data that has been sent to it, and can be triggered on both read() and write(). But the exact behavior depends on the operating system.

you've got to be shitting me.

somequixotic

AHA

Bob

This is ridiculous.

somequixotic

so in other words, the browser is doing a write() on your TCP socket and you didn't read all of its data, so it's throwing a shit fit over it

Bob

16:06

I don't know what to say.

I DON'T WANT YOUR DAMN DATA

:P

somequixotic

lol

the browser is acting like an angry parent -- you cut them off mid-sentence and they're mad

tldp.org/LDP/abs/html/devref1.html#DEVTCP

XD I wonder if you can use that

sure beats netcat

> There is one caveat: some systems (Debian included) don’t enable /dev/tcp. I don’t know why, but they don’t. So make sure your target system has it before coding this up.

that's stupid :(

Bob

Nope. I tried discarding all available data. No go.

@somequixotic o.O

Lemme just check.

somequixotic

@Bob well there's one more thing to try: download a working implementation of a basic HTTP/1.0 server (in Java, C, whatever!) and wireshark it responding correctly to your web browser, and see what you're doing wrong

assuming your browser isn't like "Connection reset O_O" when you attempt to use it

you probably can't use apache or lighttpd or nginx for that since they're all HTTP/1.1 servers

Bob

@somequixotic Nope, /dev/tcp does not exist on the uni machines

@somequixotic I'm pretty sure it's the didn't-read-all-input thing

somequixotic

@Bob suck. by the way, that "device" is not actually an inode in the filesystem; bash just pretends that it's there

Bob

16:11

I'll just have a read loop waiting for the blank newline (end of headers)

@somequixotic Huh. So, I can't check for it with a traditional ls.

somequixotic

@Bob nope; if you look for /dev/tcp in the actual filesystem, it won't be there, but if you're running an impl of bash that supports it, builtin commands will work

you have to determine which commands are builtin and which are a coreutils executable though

if you're using GNU coreutils /bin/ls, it won't find it

if you're using bash builtin ls, it would find it if /dev/tcp is available in the bash impl.

Bob

user@wagner:~$ type ls
ls is aliased to `ls --color'

Damn.

I didn't know a builtin ls even existed.

Gowtham

Bob

user@wagner:~$ type ls
ls is /bin/ls

Ok, /dev/tcp works.

I'll fiddle with netcat a bit more, though.

somequixotic

@Bob sweet

then all you have to know is which bytes to send/receive when, and you're done

reading the RFC I would assume you know that

from an aesthetic point of view, for an assignment that says "do this purely in bash" (which I assume means you can't use an interpreter for a real programming language like Python or Ruby), using a builtin pseudo-device like /dev/tcp and a bunch of bash builtins seems to be more in the spirit of the assignment than using an external utility like nc, anyway

Bob

16:22

@somequixotic Technically, we're using sh more than bash

though, I've kinda just slipped into bash

somequixotic

nevermind, /dev/tcp is a non-starter

3

A: /dev/tcp listen instead of nc listen

Unfortunately it's impossible to do with just bash. /dev/tcp/<ip>/<port> virtual files are implemented in the way that bash tries to connect to the specified <ip>:<port> using connect(2) function. In order to create listening socket, it would have to call bind(2) function. You can check this by ...

Bob

it's more general shell scripting

@somequixotic Ah, damn.

Ok, I'm just gonna pretend HTTP/0.9 doesn't exist.

somequixotic

@Bob if the core executable sh itself makes it literally impossible to do anything like implement an HTTP server, and you're allowed to use external utilities, why not just push a payload into ruby?

it really isn't that hard in ruby; in fact, it's probably 10 times easier than doing it with nc

on top of that, Ruby is about as forgiving as possible in its core syntax -- I think it is somewhat or mostly compatible with the syntax of VB6, JavaScript, and C, all at the same time, which is insane

Bob

@somequixotic I'm pretty sure that's beyond the scope of this task...

somequixotic

@Bob then this task is stupid -- shell scripting while having your hands tied is no scripting at all!

the whole point of shell scripting is to use the right tool for the job

"do X that's impossible in pure sh and doesn't work all that well with a few clumsy common tools" is exactly the type of task where I'd want to whip out ruby or python.

Bob

16:39

@somequixotic yay, it works...

somequixotic

or you could write a new module (native code compiled into a shared library) for bash and use the enable builtin to enable your HTTP Server command :DD

@Bob what? nc?

Bob

it was the unread data

-_-

of all the things...

Hi folks, i'm recently a OSX user, and I have a linux server at my office that I would work on via SSH so I use Terminal, but when i'm using vim my keyboard dosn't work has expected, does someone know the right configuration to let me use all my keyboard keys ?

jokerdino

17:31

what do you mean?

how familiar are you with vim?

JonathanLaf

I don't think it's a vim problem, is more a key binding problem in Terminal.app

Bob

@jokerdino I mean... it looks like binary data, but.... why is it being assigned to a variable?

@JonathanLaf Do those same keys work outside of vim?

jokerdino

@Bob yeah

JonathanLaf

@Bob yeah... and they work inside vim until i enter the insertion mode...

Bob

@JonathanLaf Uhm. Which keys are these?

Insertion mode is for, y'know, insertion of text.

JonathanLaf

i'm talking about the navigation arrow (as far that I can see right now but I havn't work that much with it because right now it's impossible to move inside the document..)

@JonathanLaf vim? as an IDE? hahahahahahahahah-- oh, you didn't want me to laugh

There's this thing called {Eclipse/Visual Studio/XCode/NetBeans/Code::Blocks/PrimalScript/...} that actually qualifies as a proper IDE. It's nice.

@somequixotic kind of but i cant find a tutorial for something like this

Vim works in a pinch, and is about as good as you'll get via ssh without X forwarding, but it's not great for big projects.

@Bob it's a local server freshly installed this morning not suposed to get a latency :P

user2162942

@somequixotic Thanks for pointing me in the right direction

Bob

@user2162942 AJAX is basically updating a page without loading a whole new one, by using JS to send requests and parse the response.

@user2162942 start simple, and build up from there

first try just writing a simple php page that returns a plain text string like "hello"

then call that page with an XMLHttpRequest and use the JavaScript alert function to display the result in a popup

user2162942

i have already tried simple php scripts that work

Bob

@JonathanLaf You might also want to look into how your terminal is sending escape sequences, then.

somequixotic

if you can do that, you're halfway there

Bob

echo $TERM on both the local and remote

user2162942

Yep! Thanks again!

do you know any good tutorial for an ajax chat room?

Bob

17:53

@user2162942 you could just look for existing implementations and reverse engineer them

JonathanLaf

medialog@medialog-linux:~/public_html/jlafleur$ echo $TERM
xterm-256color

Jonathan-Lafleur:~ medialog$ echo $TERM
xterm-256color

somequixotic

@user2162942 you're using one right now

Bob

or, y'know

google.com.au/search?hl=en&q=ajax%20php%20chat

first result: tutorialzine.com/2010/10/ajax-web-chat-php-mysql

user2162942

Haha! I'll try those ideas.

Bob

@JonathanLaf Looks pretty standard.

JonathanLaf

17:54

Yeah

somequixotic

in Chrome or Firefox, right-click and inspect element on this chat and you can eventually get at the javascript... put your browser behind Fiddler proxy and you can see the kind of stuff it does

Bob

Ah, I really should go to sleep.

somequixotic

AFAIK, our chat periodically requests an /event URL on the chat server to get updates

Bob

@somequixotic I'd really not recommend trying to read the minified JS @_@

somequixotic

@Bob JS beautifier works.

user2162942

17:55

whats Fiddler proxy?

Bob

When I said reverse engineer, I meant find a open source implementation :P

somequixotic

@user2162942 fiddler2.com

Bob

@somequixotic For syntax. But the variable names can still cause a bunch of confusion.

somequixotic

@Bob that's not quite reverse engineering >_>

that's more like forward engineering

Bob

Well.. ya.

somequixotic

17:56

@Bob ??? you don't call your own variables a, b, etc? :P

JonathanLaf

@Bob I think i just found something...

I used vi (normaly an alias of vim) but right now there's no vim installed, I'm installing it right now...

Bob

o.O

@JonathanLaf You might want to reset your ~/.vimrc, then.

somequixotic

I prefer cat and echo over regular old vim

Bob

@somequixotic Sure, sure. Next you'll be telling me you use butterflies.
