proxy or sshtunnel (Dynamic Port Forwarding)

@mikael
Yes, I would like to access the sshtunnel or proxy on the jump server to connect to the intranet.

I also want to access the web site via the jump server in addition to the intranet access.

@tomomo, check out this convenient-looking sshtunnel module.

It is Python-only, installed cleanly and did not throw any errors before not connecting because I do not have a convenient SSH endpoint around.

@mikael
Tried sshtunnel.
I was connected to the jump server, but I could not access the site via the jump server.

tomomo

from sshtunnel import SSHTunnelForwarder
import ui

server = SSHTunnelForwarder(
	'123.123.123.123',
	ssh_username='user',
	ssh_password='pass',
	remote_bind_address=('127.0.0.1',3128)
)
server.start()

main = ui.ScrollView(frame=(0, 0, 375, 812))
main.content_size = (375, 812)
wv = ui.WebView(frame=(0, 0, *main.content_size))
wv.load_url('http://10.10.10.254')
main.add_subview(wv)
main.present('panel')

@tomomo, I suggest you check your understanding of which sshtunnel address is which. Is your jump server address really 123.123.123.123? load_url should use 127.0.0.1, i.e. the local endpoint of the tunnel - you can use the local_bind_address to specify the port.

Also, would recommend the with ... as tunnel: format to manage the opening and closing of the tunnel.

(ScrollView is not needed, WebView can scroll on its own.)

@mikael
123.123.123.123 is dummy ip address.
ssh username and password is dummy.

from sshtunnel import SSHTunnelForwarder
import ui

with SSHTunnelForwarder(
	'serveripaddress',
	ssh_username='user',
	ssh_password='pass',
	remote_bind_address=('127.0.0.1',80),
	local_bind_address=('127.0.0.1',80)
) as server:
	wv = ui.WebView()
	wv.load_url('http://127.0.0.1')
	#wv.load_url('https://www.google.co.jp')
	wv.present('panel')

I also put apache in the jump server for testing.

I tried to change the source code, but I was logged in with ssh.However, the ssh session seems to be closed immediately and the process will not continue.

mikael

@tomomo, present is not modal, so the context closes immediately after, closing the tunnel.

Adding wv.wait_modal() after it should wait until you close the view.

You need to set up the proxy configuration in the NSURLSessionConfiguration object before creating the NSURLSession object.

Yes, it is possible to use proxy or sshtunnel (Dynamic Port Forwarding) in UIWebView. However, you will need to set up your own proxy server to do so. It is important to note that UIWebView does not support SOCKS proxies, so you will need to use an HTTP proxy instead. You can get it from https://soax.com/online-facebook-messenger-proxy. To set up a proxy in UIWebView, you will need to create a configuration object to set the proxy settings. This object will contain the proxy's host, port, username, and password (if applicable) and any other required configuration settings. You can then pass this configuration object to the UIWebView instance's session configuration. This will make the proxy settings active for the UIWebView instance.

Did you manage to solve the problem?

Additionally, you are leaking DNS requests everywhere. Otherwise, your local computer will use your shift proxy io connection to seek DNS names, thus you must use an HTTP proxy on the SSH box. But if you're worried about being recognized, your VPS is just another IP address associated with your name. You should only use your approach if you don't trust your local connection but don't care about privacy.

You should only use your approach if you don't trust your local connection but don't care about privacy. Consider the scenario where you are using unencrypted wifi at a coffee shop. You can use your solution to visit non-SSL websites without worrying about other customers in the coffee shop spying on you.
