System wide `ssh_config` support

[ihipop]

I'v defined a lot of host items in ~/.ssh/config
and I have a system wine ssh_agent started
Could you please display these items from ~/.ssh/config in electerm's bookmarks
( even read only items at first in a special category) and the ssh client will use System wide ssh_agent
That will provider a same experience both in command line native ssh client and electerm
and save a lot of time to migrate from command line

[zxdong262]

would you please post a sample file of your ~/.ssh/config

[ihipop]

@zxdong262

You don‘t need to parse the items in ~/.ssh/config，there a some Utils/Libraries available.

For example ,I have these items in my ~/.ssh/config

ServerAliveInterval 15
ControlPath ~/.ssh/cm-%r@%h:%p
ControlMaster auto
ControlPersist 2m

Host github.com
	User git
	IdentityFile ~/.ssh/Git/id_rsa_git

#Example for SSH GateWay
Host Relay
	HostName xxx.xxx.xxx.xxx
	User root
	Port 2233
	LocalForward 2221 web-1:22
	LocalForward 2222 web-2:22
	#We don't define IdentityFile for this item because it use default ssh key
Host www-web-1
     	Hostname web-1
     	User root
     	Port 22
	ProxyJump Relay
	IdentityFile ~/.ssh/relay_rsa
Host www-web-2
     	Hostname web-2
     	User root
     	Port 22
	ProxyCommand ssh -W  %h:%p xinglin-Relay
	IdentityFile ~/.ssh/relay_rsa
Host svc-gitlab
	Hostname gitlab
	User root
	ProxyJump Relay	
	IdentityFile ~/.ssh/relay_rsa

#优酷路由宝
Host youku-LYB
	Hostname 192.168.123.1
	User admin
#VPS
Host pop-fremont-01
	Hostname example.com
	User abc
	Port 233

If I want to Connect to Host youku-LYB,I just type

ssh youku-LYB

the native ssh client will connect to 192.168.123.1 at port 22 use user root

If I want to Connect to Host pop-fremont-01 ,I just type

ssh pop-fremont-01

the native ssh client will connect to example.com at port 233 use user abc

And，For example，the Host www-web-1 is behind Host Relay ,I just type

ssh www-web-1

the native ssh client will connect to web-1 via Host Relay,the Hostname web-1 of Host www-web-1 will be resolved use the Host Relay

I can do some very complex config in ~/.ssh/config，and use it just with a simple name of Host

And ，Most Linux Desktop Have a global ssh-agent started, Means that if I only need to call ssh-add ~/.ssh/relay_rsa and enter the password only once. The next call of ~/.ssh/relay_rsa will handled by ssh-agent automaticly

If you can display Items of ~/.ssh/config,then simple call ssh command is just enough

You don‘t need to parse the items in ~/.ssh/config，there a some Utils/Libraries available.

And add the support for ~/.ssh/config will let electerm to have the ability to access/upload files behind a ssh gateway,with a little code to write

[ihipop]

@zxdong262 I downloaded the pre-release，but it not work correctly, It can only display the first item of ~/.ssh/config

electerm/app/lib/ssh-config.js

Lines 12 to 42 in fb08620

	try {
	const configStr = require('fs').readFileSync(
	resolve(home, '.ssh', 'config')
	).toString()
	config = sshConfig.parse(configStr).map((c, i) => {
	let {param, value, config} = c
	if (param !== 'Host') {
	return null
	}
	let host = (_.find(config, f => f.param === 'HostName') || {}).value
	if (!host) {
	return null
	}
	let port = (_.find(config, f => f.param === 'Port') || { value: defaultPort }).value
	let username = (_.find(config, f => f.param === 'User') || {}).value
	if (!username) {
	return null
	}
	return {
	host,
	username,
	port,
	title: value,
	type: 'ssh-config',
	id: 'ssh' + i
	}
	}).filter(d => d)
	} catch (e) {
	console.log('no $HOME/.ssh/config, but it is ok')
	}

Manually parsed host name and port,catch (e) without log it,I can‘t provider any information...

[zxdong262]

@ihipop Hostname -> HostName will fix it. Hostname will be supported in next release.

[ihipop]

@zxdong262
Hostname -> HostName fix the first issue,but still have problem with Host behind a Relay,because you Manually parsed host name and port, please see if this helps https://www.npmjs.com/package/ssh-config
Or even just consider call ssh HostItem command directly(this may not work for sftp because you use your own Interactive UI)

@ihipop thanks.
