ttyd's Issues

brew install failure

This will cause binary package installations to fail.
This can happen if you install osx-gcc-installer or RailsInstaller.
To restore it, you must reinstall OS X or restore the binary from
the OS packages.

single session

Hi,

Thanks for an awesome little software!

I recently came across ttyd after an extensive google search thinking it was exactly what I needed. However, after starting to use it I noticed that the behaviour is slightly different:

ttyd will re-initialise every time a client connects with a web-browser. That means if I use it to run a command, say bash, it means it will create a new bash for every client that connects.

However, what I want is that it shares the same session with every client. Actually, I dont even need multiple clients. I would be happy if it disconnected one when accepting another.

So my questions are:

Does ttyd support this mode of operation?
If no, is that something you are planning to implement?

Thanks a lot

can not use lrzsz

When inputting rz/sz in commandline, terminal will be stuck. Is it possible for author to create a similar function to realize it?

memory corruption in tty_server_new

I found a memory corruption error in DomTerm. This was in code imported from ttyd, which appears to have the same bug: The cmd_len value does not include space for the final nul. Alternatively, you could:

ts->command = xmalloc(cmd_len+1);

The second part of the patch is optional - it just seems strange to use sprintf there. Is there some reason for it?

server-patch.txt

ttyd listens by default on tcp 7681 on ALL interfaces, IPv4/IPv6, without any firewall rules.

cross-post from openwrt/packages#3271

please use secure defaults if ttyd is started without any configuration

make it work only via https TLS 1.2/1.3, without http and change it so by default it listens only on local-network and only on IPv4 reserved-local addresses. This could be changed later from configuration, but the defaults should not allow access from outside the local network.

Windows support

https://github.com/rprichard/winpty

Client is automatically reconnected after typing `exit`

By typing exit, the client should go into a "never connect again" state and should prevent it from reconnecting..

CJK and IME support

hterm cannot handle CJK(Chinese, Japanese, Korean) characters, emojis and IMEs correctly.

There's some works for this: vercel/hyper#214, vercel/hyper#740 , but seems not perfect yet.

I'm considering xterm.js as a replacement.

process terminates on webpage exit

How do I stop this? (Even if it is not a bug)

[Feature] Static binary releases

I just want to propose to provide static binary releases. There are some use-cases when you only want to share a session once, and currently, I resort to gotty since go produces portable binaries by design. ttyd has better support for unicode from my experience and this is why I would love to use ttyd...

P.S. It might be worth to consider musl libc instead of glibc for static compilation.

debug flag does not work

neither ttypd --debug bash nor ttyd --debug -- bash work
tested in the ubuntu docker container.

ldomterm - a fork of ttyd using DomTerm rather than xterm.js

FYI: I have created a "pseudo-fork" of ttyd which uses DomTerm for the terminal emulator logic (rather than xterm.js). The server application, ldomterm, is basically ttyd, but with lots of changes to serve up DomTerm rather than xterm.js.

You can specify a --browser[=command] which uses command to automatically start a client session in a web browser. This option (which is the default if --port is not specified) implies --port 0 --once.

If you run ldomterm with no arguments it is equivalent to:

ldomterm --port 0 --once --browser="xdg-open %U" /bin/bash

The sources are on GitHub, with the ldomterm sources in the lws-term directory. Build it with ./configure --with-libwebsockets && make

DomTerm has many advantages: you can "print" images and embed general HTML; better xterm emulation (fewer vttest failures); optional input editing (a poor man's readline); export to clean HTML; and more.

Feedback welcome - if there are any xterm.js features missing (or I broke a ttyd feature) please let me know. From the website of xterm.js I gather it wins in the areas of CJK and IME.

(This isn't really an "issue", but I didn't know where else to announce this. I couldn't find an email address.)

要是能在最顶部加个工具栏，管理ssh 连接，快速连接到某台服务器的功能，那就太棒了

choose port to listen

We can listen to the port 0~~1023 if we have the root access to run the program, however 1~~1023 ports are "privileged" ports. It may not safe if we listen these ports.
So in the code
if (info.port < 0) {
fprintf(stderr, "ttyd: invalid port: %s\n", optarg);
return -1;
}
Do we need to change the condition if( info.port < 0) to if(info.port < 1024)?

Customizing Webfonts

First of all, great project. I've been trying to find something like this for a while now.

I'm trying to use this project to create remote development environments. I already have docker images which I can use for development environments, so all I had to do was add ttyd to one of my images.

My issue at the moment is that I'm using customized fonts (for vim airline and powerline) which normally can be set from the terminal's options. I'd just need some way to set the font as well as load webfonts into the client.

p.s.: This is what it looks so far.

The last line cannot be seen sometimes

Seems that algorithm to calculate available lines have some bugs.

Listen on file socket

Is it possible to listen on socket rather than network port?

长时间运行出现ERROR：pthread_create

之前运行一切正常，然后过了一个晚上就无法建立连接了，看了一下后台日志，都是ERROR：pthread_create

ppa using outdated libwebsockets

binary in PPA is using an outdated libwebsockets so that setgid is not called before setuid and a privilege drop may fail:

warmcat/libwebsockets@0a9bd7e

segmentation fault

Latest Chrome Requires SAN field in SSL certificate

It would be better to update the openssl commands in README to conform this change. Otherwise generated certificate will not be accepted by latest Google Chrome.

我看监听端口写死,是否可以配置呢~

homebrew update before installing

We would better to update homebrew before we install ttyd, otherwise we might fail in installing libwebsockets.
This is the error message:

Porting to OpenBSD : length mismatch and invalid return

Hello,

After fixing compilation ( just a few defines for STAILQ and c99 )
i am trying to run the daemon.

It stays in this state and does not provide content

[2017/03/03 12:52:26:0036] NOTICE: wsi 0xc3e80cef600: TIMEDOUT WAITING on 3 (did hdr 0, ah 0xc3ee9c7d000, wl 0, pfd events 0)

i ran it like this :
ttyd -O --debug 7 --index /usr/ports/pobj/ttyd-1.3.0/ttyd-1.3.0/html/index.html /bin/ksh

When the daemon serve small file it s okay, but it looks like the c code forgot to write when
the socket is ready.

curl http://127.0.0.1/ show the html package file is cut :

By using nginx/1.10.1 as a proxy see https://www.nginx.com/blog/websocket-nginx/

i can load the all index.html but other error occurs :

WebSocket connection to 'ws://my.com/index.htmlws' failed: Error during WebSocket handshake: Unexpected response code: 502

Because the full referrer of my request is used ( i called with index.html )

By playing arounf with nginx i got something working but the issues should be fixed.

too many dependencies

https://ruby-china.org/topics/31081

找了一下类似的程序，发现了 Wetty 和 GoTTY，但是 Wetty 需要 node 运行环境， GoTTY 编译后的二进制文件太大，多数路由器的 flash 都比较小，不适合集成到路由器固件里。

加上这些依赖，应该比GoTTY不小啊。

Docker packaging: Improve Alpine image

Based on comments on 8433e75 ,

as soon as Alpine Linux 3.6 will be released (https://bugs.alpinelinux.org/versions/115 - 1st of May 2017) , the alpine Docker declination of this image can be improved with the followings:

Use the new "ttyd" Alpine package, courtesy of @jirutka (cf. https://pkgs.alpinelinux.org/packages?name=ttyd&branch=&repo=&arch=&maintainer= )
Don't compile libwebsockets anymore ( There is an Alpine package for this: https://pkgs.alpinelinux.org/packages?name=libwebsockets&branch=&repo=&arch=&maintainer= ).
** N.B. Is this package installed as dependency as the ttyd one ?
Do no use the Alpine GlibC hack anymore, since no need to compile libwebsockets

Compile error on Ubuntu 14.04

execute above command and notify fatal error:

I already downloaded libwebsockets source code and install to fix this compile error.

Refresh with cache empty after 5 mn

Just build and ran ttyd 1.3.3 on openBSD,
the programs hangs like before my return 0 patch but after a minute

The log always show [2017/07/18 10:16:28:2778] NOTICE: sending SIGHUP (1) to process 78440

Maybe it can be reproduced when emptying cache on other platform ?

Completion of error handling

Would you like to add more error handling for return values from functions like the following?

malloc ⇒ tty_server_new
pthread_mutex_lock ⇒ callback_tty
