ssheasy's Introduction

ssheasy

Source repositorty of the online ssh, sftp client ssheasy.com

Building, running locally

docker-compose up

This will compile the wasm ssh, sftp client, the proxy component that proxies tcp connections for the client running in the browser through websocket and sets up nginx server serving the web frontend. Additionaly prometheus and grafana is set up as well to monitor the connections proxied. An sshd is also started in a container for testing.

Testing

For testing docker-compose sets up an sshd in a separate container. After starting up the stack with docker-compose up open http://localhost:8080 in your browser and use the host testssh with user root and password root.

Project structure

nginx: web server config, Dockerfile for building the wasm ssh/sftp client
proxy: golang proxy service for tunneling tcp connections through websocket
web: source of the ssh, sftp wasm client, and the httml for the frontend

Filemanager UI

The filemanager is based on forked version) of angular-filemanager. The fork replaces the backend api calls with calls to the wasm sftp client. The fork has to be built separately and copied to the web/html/node_modules directory.

ssheasy's Issues

is IPv6 supported ?

hi,very nice tool,
work fine with IPv4 host but throw an error when I try to connect IPv6 host

error:
cannot connect to host: dial tcp [2a02:8429:614a:6901:ba27:ebff:xxxxx:xxxxx]:22: connect: cannot assign requested address

Non-issue

Apologies - thought I found an issue, then discovered it was an issue between the keyboard and screen. Don't seem to be able to delete this though.

Certificate expired

Is it possible to make a ssheasy using Php?

License

First of all, your product is really useful, can you please make the licensing clear as I might like to use this in one of my personal project

Use ssheasy as vpn

Hi, my ISP has blocked my server so i can't connect via SSH using Putty
But when i try ssh through ssheasy i have no problem conncting

I am wondering that can i use ssheasy to connect to my server as a vpn(ssh tunnel)

Compression

Could you please add zlib compression, like with ssh -C? Thanks!

ssh window keeps collapsing

The ssh window always shrinks to one line

How can I change the terminal window size

How can I modify the default size of the terminal window?

license?

project is missing a LICENSE file, and therefore i cannot use this code

Can't run on Cloudflare Workers

Hello,

Our team were interested in running an SSH client on Cloudflare Workers, and ssheasy seems to be a great fit. However, we hit a snag of not being able to connect to the proxy server.

After debugging, it turned out that the implementation of github.com/hullarb/dom/net/ws/wsconn_js uses new Function() to create the WebSocket instance, which is not allowed in such serverless environment.

Since github.com/hullarb/dom has no Issues reporting, I figure to report here, since it's related to ssheasy anyway.

Is there a way we can avoid using new Function()?

It showed me the initial screen of rlgallery, but I can not type anything.

SSH Key Support

My private key is unencrypted. It is loaded automatically in a MacOS zsh shell via this entry in .zshrc:

ssh-add -q ~/.ssh/id_rsa

Here is my ssh config sample:


## Global host options
Host *
	ServerAliveInterval 120
	ServerAliveCountMax 2
	Compression yes
	MACS  hmac-sha2-512,hmac-sha1
	ForwardAgent yes
	StrictHostKeyChecking no
	HostkeyAlgorithms +ssh-rsa,ssh-dss
	KexAlgorithms +diffie-hellman-group1-sha1
	PubkeyAcceptedKeyTypes +ssh-rsa,ssh-dss
	StrictHostKeyChecking no

Host    ud11                 
	Hostname 10.122.85.22 
		ForwardAgent yes
		IdentityFile ~/.ssh/id_rsa
		User justin
		HostkeyAlgorithms +ssh-rsa,ssh-dss
		KexAlgorithms +diffie-hellman-group1-sha1
		PubkeyAcceptedKeyTypes +ssh-rsa,ssh-dss
		StrictHostKeyChecking no

This host is on the office LAN and is reachable via a VPN and I am it works via command line SSH: OpenSSH_9.0p1, LibreSSL 3.3.6

I get this error: cannot connect to host: dial tcp 10.122.85.22 :22: i/o timeout

Could you add a license to the repo?

Hi there, I'm interested in playing with this code and possibly contributing back some improvements... but I'm not sure how it works when there's no license file in the repository.

Could you add a license file? I'm a big fan of the MIT license encase you needed a suggestion :)

Thanks!

Send SSH Command programmatic from browser

Hi,
SSHEasy now wasm ssh client and run entirely in browser, so can I using ssheasy to send an ssh command programmatically from my browser to my local ssh server in a local network where I open ssheasy.com in same local network ?

Thanks,
