Reading Files on network box
-
Facts: 0) I'm writing a .Net Core 3.1 command line app (using C#) to read text files on some Raspberry Pi machines on the network. This app will be able to run on either Windows or Linux. 1) The files in question are in the
/etc,/procand/sysfolders. 2) I don't want to create shares of these folders. 3) I'd prefer not to have to install/configure anything on the remote boxes (if at all possible). 4) I know the user ids and passwords for the remote boxes, and am aware that I have to somehow use these credentials in order to "connect" to the remote boxes). 5) I don't want to use another language. I mean, doNet Core is supposed to be cross-platform, right? Problem: How do I go about reading a file on a remote linux box? I've tried a number of ways to do this, but I keep getting the following exception:"The network name cannot be found. : '\\\\192.168.1.10\\sys\\class\\thermal\\thermal_zone0\\temp'"(BTW, when running in Windows, the exception is presented with backslashes. I'm actually using forward slashes.)".45 ACP - because shooting twice is just silly" - JSOP, 2010

[GitHub - sshnet/SSH.NET: SSH.NET is a Secure Shell (SSH) library for .NET, optimized for parallelism.](https://github.com/sshnet/SSH.NET) I have not looked too closely at it, but at worst you could use the SCP functionality to copy the file to the local host and then read them in the normal way.
Keep Calm and Carry On

They don't mention anything about .Net Core... :(

Quote:
This is the first release of SSH.NET providing support for .NET Core and Universal Windows Platform 10
The latest "stable" release is 2016.1.0 and 2020.0.0 is in beta. Here's an example for file upload using SSH.NET and .Net Core: Upload File to SFTP Server using C# | DotNet Core | SSH.NET[^].

FTP would require both installation and configuration on the Linux machines. SSH service is installed by default but not enabled.
Is not FTP installed by default on all Linux machines nowadays? I honestly would have taken that for granted. FTP was developed in the days when you measured program size in kilobytes. The protocol is so simple that a student could implement it as homework assignment #3. I can't see any reason for taking it out.

No, not anymore. There are better replacements such as SFTP or SCP. Curl or wget can be used as FTP clients if absolutely necessary.

Those days nobody could imagine the need for network security. FTP transmits everything, including user credentials, in cleartext. The protocol design makes it difficult to pass through firewalls without causing additional security risks. In general, it's just too dangerous and should not be used.

If you are connecting to an FTP server that requires credentials and supports Secure Sockets Layer (SSL), you should set EnableSsl to true.
And there's one's own encryption / decryption, staging directories, etc. Keep the baby.

I added SshNet with Nuget, and it workds great. :)
using SshNet;
using (var client = new SshClient("192.168.1.10", "userid", "password"))
{
client.Connect();
string data = string.Empty;
using (SshCommand cmd = client.CreateCommand("cat /proc/cpuinfo"))

When you pry the gun from my cold dead hands, be careful - the barrel will be very hot. - JSOP, 2013Do you want to force linux to do the windows thing, or windows to do the linux thing? For the former run samba on the linux box and create shares you can access from windows. This will probably suck, the degree to which it sucks will depend on the file system you are using on the linux side. For the latter you can run an ftp server on the linux side or setup ssh and use scp. These will suck less.

I found a solution - use the SshNet library and I don't have to do anything on the other pi's on the network.

If those files aren't shared, how do you expect to read them? after all, if those remote files were on Windows, you'd still need to share them for a remote computer to read them. You appear to be under the impression that, on Linux, all files are shared by default. I can assure you that this is not the case.
[...] How do I go about reading a file on a remote linux box?
Same way you would on a Windows box: you'd create a share. A second option is to install some sort of file server on the Pis(ftp, http, ssh/scp, etc) and use that to copy the files across.

You really should read the whole thread. The solution has been found.
