Hello,
It looks like you're using dartssh2 in browser. Currently no browser supports opening TCP connections and to use dartssh2 you have to either compile your app to desktop/mobile version, or implement your own SSHSocket that relies on other underlying transports such as WebSocket or SSE.

[xtyxtyx]

By the way I'd like to hear what you want to build with dartssh2 so I can tailor the package to better fit your (and other's) needs.

Two important things:

1. Regarding a fix for the error IN ADDITION TO the implementation of our own SSHSocket while waiting for you to get it working, in ssh_socket.dart, line 5 should read if (dart.library.js) 'package:dartssh2/src/socket/ssh_socket_js.dart';, not if (dart.library.js) 'package:dartssh2/next/socket/ssh_socket_js.dart';.
   The problem lies in the fact that there is no next directory.

By the way I'd like to hear what you want to build with dartssh2 so I can tailor the package to better fit your (and other's) needs.

2. I am using dartssh2 to connect to a proxy server, which then connects to other devices from there. Using XTerm to customize and handle the terminal display on the web. Which means, it would be nice to have a friendly way to print responses back for my terminal, while filtering only the needed responses...for some things need to be handled autonomously.

Thanks for reporting! @warrenm1
The import path issue has been fixed in 2.5.0.

while filtering only the needed responses

Could you provide an example about this?

[warrenm1]

@xtyxtyx when using the dartssh, we implemented the SSHClient thusly

SSHClient(
hostport: Uri.parse(_host),
login: _username,
print: print,
termWidth: 80,
termHeight: 25,
termvar: 'xterm-256color',
getPassword: () => utf8.encodeBytes(_password),
response: (transport, data) {
if (!_baseConnected) {
if (data.contains('Are you sure you want to continue connecting')) {
_client.sendChannelData(utf8.encodeBytes('yes\n'));
}
if (data.contains('root@localhost's password:')) {
_client.sendChannelData(utf8.encodeBytes('$_password\n'));
setState(() {
_delayIndex = 0;
// additional local logic
});
}
} else {
_terminal.write(data);
}
},
success: () async {
_proxyConnected = true;
_terminal.write('proxy connected.\n\r');
// additional logic to connect to devices
},
disconnected: () {
_terminal.write('disconnected.\n\r');
if (mounted) {
setState(() {
// local variable logic
});
}
},
debugPrint: (str) {
// logging logic
},
tracePrint: (str) {
// logging logic
});

Particularly the logic found within the response value.

[warrenm1]

@xtyxtyx just to clarify, needing to verify that my ssh connection within the proxy (that I used the SSHClient to connect to) actually occurred, otherwise I will be in an endless loop of connecting->exposing device to a different port...which closes the ssh session->connecting to that new port-> exposing device to a different port...etc

We had some local logic to account for that loop, but get stuck in that loop without the response handled similarly to how it was in dartssh.
