2015/08/19 20:56:32 New client connected: <my ip>:26736
2015/08/19 20:56:32 Failed to upgrade connection

Getting this error sometimes, only on Chrome. Firefox runs it well.
Client shows only a blank page.
Yesterday I had tried it out already and everything was fine.

Gotty is very awesome.

When I set ' --once' , the console can not reconnect.
So I cannot use gotty in a unstable network with once feature.

Thanks .

For environments where people use w3m and cannot run hterm,

Terminal A: gotty -w tmux new -A -s foo
Then,
Terminal B gotty -x

It would be great if terminal B sends a broadcast packet and automatically discovers terminal A.

Very nice project!

I was planning to try it, and my first idea has been to use it inside Docker, for security reasons.

You suggest to launch docker via gotty, but I think this is a vulnerability.

As discussed in the past on docker security, it might be possible to crash the docker container, allowing to execute commands on the host.

Wouldn't it be better to launch docker, then run gotty INSIDE docker?

Copy and paste wold be an awesome improvement!

Thank you!

It would be nice to be able to use custom fonts. I added this with the raw one, it was pretty straight forward if I remember correctly.

Could it be possible to add Linux ARMHF (Raspberry Pi) releases ?

Thanks !

Thanks for this apps, run fine on Qnap NAS QPKG is available here

http://forum.qnap.com/viewtopic.php?f=320&t=113304

but i wonder why Midnight commander stay frozen.. not sure how to debug

I would be nice if it's possible to deliver parameters or information about the client to the command to be executed when client connects to gotty.

Example1:
gotty /opt/cmd
http://hostname:8080/?arg1=foo&arg2=bar => gotty will execute /opt/cmd arg1=foo arg2=bar

In terms of security reasons it would be reasonable if it's possible to limit what arguments should be delivered and what data could be into them (only digits / only A-Z)?

Example2:
gotty /opt/cmd %CLIENT_IP_ADDRESS%
192.168.1.10 connects to http://hostname:8080/ => gotty will execute /opt/cmd 192.168.1.10

For me, if I run gotty --once -w vim then connect in the browser, then close the browser tab, I find that gotty is still running.

Hi Yudai,

can it be possible to set authentification using the uid 0 user for example.

this could allow Qnap users to log with the admin user (no root on qnap) set on their box, instead to set a custom user/password

I think it could be a good enhancement for Gotty.

May be you use go-bindata, even through this program can work, but hterm.js still not found.

Hi, my use case is I'm trying to provide an in-browser SSH client, however I'll be spawning up the gotty process when the request comes in and I want to kill it when the user exits ssh. What I'm using is:

gotty -w ssh [email protected]

The problem currently I'm seeing is, when I go to browser and exit the ssh prompt (with exit command for instance), the gotty process stays alive and keeps accepting connections and new connections cause ssh command above to be restarted.

What I do need instead is, gotty server to quit when user quits by exiting the process so that I can garbage collect resources and next time user visits my service (say, http://example.com/ssh/[email protected]) I will spawn another gotty server.

@yudai does it sound like a good proposal to have an argument that makes the gotty server quit once the executed process quits (rather than staying alive and re-execing the specified command when a new request comes in)?

To reproduce:

$ gotty tmux new -A -s gotty top

Connect via tmux:

tmux att -t gotty

• Connect to localhost:8080 to view the terminal in a browser
• Inside tmux, create a new pane and type something
• Now type clear to clear the terminal buffer
• Connect with another client
• -> The contents which were just cleared reappear

gotty installed by instruction by the brew.
keys generated by instruction.

at start gotty logs this issue:
crypto/tls: failed to parse certificate PEM data

It would be helpful if the IP addresses of the clients could be part of the logging. Working on an educational application for shared terminal window and it would help with debugging.

There are many, many services which supply free DNS and provide an API to register them.
We should evaluate those and pick a few that are safe to use and preferably open sourced with a permissive license.
This will allow us to share the terminal outside of the current network we're on.

Suggestion: "GoTTY - #{command} (#{hostname})"

Saw a crash when a second client connected to gotty into a tmux session holding htop (i.e., ran via gotty tmux attach -t gotty to show it to a coworker, 'cause this is pretty awesome).

$ tmux new-session -s gotty htop
…
$ gotty tmux attach -t gotty

Unfortunately haven't been able to reproduce it, so possibly a fluke. Figured I'd open an issue and if I come up on other details I'll amend the issue.

when i compiled source code,found code err

mkdir bindata
make: *** No rule to make target `libapps/hterm/js/*.js', needed by `bindata/hterm.js'.  Stop.

The alt key ("option key") on OS X gets mapped to the meta key, making it impossible to write e.g. "@" (on my keyboard layout "@" is alt+2) and a range of other characters (©, £, $, ∞, §, |, [, ], etc.).

Work very well in OS X 10.10.5, Firefox 40.0.3

Hi,

Is it possible to have a 32 bit binary version in Release archive ?

Thanks

When doing dumb stuff like cat /dev/random or cat on binaries which yield unprintable characters (and may screw up a terminal under "normal" circumstances ) lead to a disconnection. This is especially bad when byobu (tmux wrapper) runs in the background, which makes reconnection impossible ;-).

I don't know if this is fixable, but I thought worth mentioning.

It would be nice if you could disable the resizing feature. Overlapping areas could be accessed via a scrollbar inside the browser.

Hi Master Yudai

the actual binary release is for ARM6, possible to have ARM5 version, i am sure some qnap user will love your application

thanks a lot ,

So that it's more noticeable.

Adding a "-d" flag or something similar to run gotty as a daemon process will prevent taking up the terminal.

gotty --random-url --permit-write top --addr 127.0.0.1

When I go to the page. I get 404 not found.

Hi, i am trying to install this app in Windows, but getting the following error :

D:\projects>go get github.com/yudai/gotty

Is this a Windows specific issue?

Unicode symbols are not interpreted correctly during input from the browser, while terminal-to-browser utf output works fine.

1st cmd - terminal input
3rd cmd - browser input
osx yosemite, darwin_amd64 gotty pre-release

It would be nice if gotty would tell the webbrowser to automatically reload the page if an old session was finished/killed and a new one was started on the same port. Should be easy to implement on the client side.

Keep up the good work! This package is a big one for me! 👍

Hello,

I was searching for this handy software and this first link http://gotty.io/ appeared.

Could you consider to change name to avoid future confusion like this one? http://gotty.io is older than this project.

Thanks.

It would be nice if there are URLs in the screen the gotty / JS could convert them into links which will open into new window.

The code should be aware if the URL continues into the next line like (typical situation in chat window):

SomeNick: Check this out: http://www.foo.com/bar/dir/something/inde
x.php that's so cool!
OtherNick: yes!

I've ran into this while showing this tool to my collegue. When ever I would run the command kitchen converge The first few people to connect are actually good, but then at some point every refresh/new connection cause the command the be ran gain.

EDIT: it seems to stop at 2... The first ps is at start with me watching, then the second one is after my collegue joined.

2015/08/23 12:20:01 URL: http://192.168.99.1:8080/

From what observe on Chrome and Safari on OS X is browsers can't open addrs like http://::1:8080/ or http://fe80::a65e:60ff:fecc:5cc7:8080/ at all. Maybe the program should just print IPv4 ones?

When setting 'color-palette-overrides' I get the following error in the javascript debug window (firefox)

[15:34:58.042] "Preference color-palette-overrides is not an array or object: {'0':'#073642','1':'#dc322f','2':'#859900','3':'#b58900','4':'#268bd2','5':'#d33682','6':'#2aa198','7':'#eee8d5','8':'#002b36','9':'#cb4b16','10':'#586e75','11':'#657b83','12':'#839496','13':'#6c71c4','14':'#93a1a1','15':'#fdf6e3'}"

In my .gotty file I intered

1. Will this ever work with Windows?
2. If it can, is windows support on the dev path?
3. What could a "regular Joe" user do to use this on windows right now? Using it in docker is the simplest option?

PS: I'm excited 😄

gotty -w vim

Default SSL support by the server must be required.

I know, it's dangerous enough.

Option 1

Allow send only arguments like run gotty --permit-arguments tailf then, access http://server.exmple.com:8080/%2Fvar%2Flog%2Fsyslog (/var/log/syslog).
(Need to take care of shell meta characters not to permit using pipe and redirects)

Option 2

Freedom mode like gotty --freedom then, access http://server.example.com:8080/tailf+%2Fvar%2Flog%2Fsyslog.

Getting defunkt processes after each connect with GoTTY. They seem to linger on after each spawn.

(PS: GoTTY is awesome btw!)

Please make this tool installable via Homebrew. 👍

Has anyone managed to successfully get Gotty working through Apache?

I can't resolve the issue of WebSocket not initializing:

As I mentioned in another issue, I'm using GoTTY as a bridge for my telnet BBS, but the colors are a bit off for VGA textmode artwork.

https://oddnetwork.org/bbs/

Awesome work, anyway! I really appreciate the app.

URL generation for something like an authentication alternative.

Add an option to generate URLs like:

https://host:8080/nairj3gnw5ja39r23

The ability for web clients to send input to the gotty'd process is awesome, but it would also be excellent to allow the user who is hosting the gotty process to use STDIN to "screencast" to consumers.

Ideal flow:

gotty nano /tmp/some/file

Gotty starts, and the tty used to start gotty acts exactly as if the command had been run without gotty. The user can "screencast" their input and results to web consumers - without web consumers necessarily being able to control the process.

Running "make" against the provided makefile immediately fails with:

make: *** No rule to make target `libapps/hterm/js/*.js', needed by `bindata/hterm.js'.  Stop.

libapps/ is an empty directory.
