Can't get on the server in a mosh.

Got the server. Debian set SSH-ключ♪ On team:

ssh -i yandex_key em0ji@51.250.23.237

I'm going to the server:

Linux rowihost 4.19.0-18-amd64 #1 SMP Debian 4.19.208-1 (2021-09-29) x86_64
The programs included with the Debian GNU/Linux system are free software;

the exact distribution terms for each program are described in the

individual files in /usr/share/doc/*/copyright.
Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent

permitted by applicable law.

Last login: Mon Nov  8 10:16:07 2021 from 31.181.190.176

There's no problem, the flight's normal, but as soon as I try to connect through. mosh:

mosh em0ji@51.250.23.237

There's a mistake in the terminal:

em0ji@51.250.23.237: Permission denied (publickey).

/usr/bin/mosh: Did not find mosh server startup message. (Have you installed mosh on your server?)

How can this problem be addressed?

Problem solved, everything has to be added. ssh-ключ Total ssh-agent♪ Okay, let's check the accessibility first. ssh-agent team:
```
eval "$(ssh-agent -s)"
```
Terminal withdrawal:
```
Agent pid 2985
```
Then we'll check that we have a generated and downloaded. SSH private key:
```
ssh-add -l
```
I've got a terminal that says,
```
The agent has no identities.
```
After that, we just need to copy the private key. ~/.ssh and command:
```
ssh-add ~/.ssh/name_key
```
And get an answer:
```
Identity added: /home/kali/.ssh/name_key (user@group)
```
After these manipulations, you can enter the abbreviated team server. ssh username@IP_server or mosh username@IP_server
Don't forget to add. ssh-agent Into the auto loading.

It's actually been a lot easier. Found the managed code of the UnityEngine Library. Networking through the ILSpy and the answer came by itself. In this case, when the server intends to send the data packages, it turns them down. The default maximum size is 128. To change it before the server starts, change the meaning: NetworkManager.connectionConfig.MaxSentMessageQueueSize 256 or more, depending on the need.UPD1: It must also be borne in mind that the Channels list on the NetworkManager should be such or similar: 0 channel = any reliable (reliable), i.e. the channel will be There's a gay-objection spawn.1 channel = any unreliable (unreliable), as this channel will All information on (from components)NetworkTransform and similar)

Giving all users a shared account is not something I would consider. You would not be able to know for certain which user did what on the system, multiple people will be sharing the same account concurrently... All in all, it's bound to get messy at some point. Imagine if one of them loses their phone, and you are forced to lock everyone out when you find out, not to mention that whoever finds the phone can log in and do harm and you would have a hard time figuring what was done by that user. I would prefer the first option. Configure each app manually before giving access to employees, save and encrypt the key pair, or the password on the device and let them choose a password for unlocking application access. This way if a phone gets lost or stolen, you can simply de-authorize the affected key / account.

Anybody can establish a connection to the SSH server which means that this information does not say anything about a successful login. Restricting access to key based authentication only is a wise choice and will prevent the typical password brute force attacks. It will not prevent a simple connect to the SSH server though, but at this stage no real harm is done yet. As for additional security settings please the the various questions about this topic on this site, like What methods are available for securing SSH?. There is no need to repeat everything here.

Yes, there are a couple of options for this, including: SSHDroid (does not require rooted phone) QuickSSHD (see this Google thread for some discussion) Dropbear (requires rooted phone, see this Droidforums thread for some discussion) SSHelper (does not require rooting; free software -- under GPL; it incorporates also code from other projects; might eventually appear in the F-Droid repository) some other free (= libre) software projects of an ssh server have been mentioned in the discussion of their potential inclusion into F-Droid Some of these apps will require you to root your device. SSHDroid, QuickSSHD and SSHelper, at least, do not (there may be others as well). There are certainly multiple choices for you to investigate depending on your requirements/desired features/etc.

There are several ways to implement the issue, in this case I use express (with pug for the html template), I define a pair of "public" folders, the "uploads" is on the outside and I charge the image that corresponds to the userID (I have it hardcoded to not make it very extensive).Folder structure:$ tree shadowfiles/ -L 4 -I node* shadowfiles/ ├── index.js ├── package.json ├── package-lock.json ├── public │ ├── css │ │ └── style.css │ └── img │ └── logo.jpg ├── uploads │ ├── 00AABBCC │ │ └── foto.png │ └── 11CCBBAA │ └── foto.png └── views └── index.pug index.js'use strict'; const express = require('express'); const app = express(); const path = require('path'); const mime = require('mime'); const fs = require('fs'); const UPLOADS_DIR = __dirname + '/uploads/'; const IMG_DIR = __dirname + '/public/img/'; const CSS_DIR = __dirname + '/public/css/'; app.set('port', 3000); app.set('view engine', 'pug') app.use('/img', express.static(IMG_DIR)); app.use('/css', express.static(CSS_DIR)); app.get('/', function (req, res) { res.render('index', { title: 'Hey', message: 'Hello there!' }) }) function getUserID(req){ // validate session get the user ID var UID = '11CCBBAA'; // return undefined; return UID; } function readImagenByID(UserID, fileName, req, res) { var filePath = UPLOADS_DIR + UserID +'/'; var file = filePath + fileName; var mimetype = mime.lookup(file); var disposition = "inline"; // para descarga: // disposition = "attachment; filename=" + fileName; fs.exists(file, function(exists){ if (exists) { res.writeHead(200, { "Content-Type": mimetype, "Content-Disposition" : disposition }); fs.createReadStream(file).pipe(res); } else { // ToDo: alternativa a devolver error, // enviar imagen default res.writeHead(400, {"Content-Type": "text/plain"}); res.end("ERROR File does NOT Exists"); } }); } app.get('/images/:IMG', function(req, res) { console.log(req.params); var UserID = getUserID(req); if (UserID && req.params.IMG) { var fileName = req.params.IMG; readImagenByID(UserID, fileName, req, res); } else { res.writeHead(400, {"Content-Type": "text/plain"}); res.end("ERROR no se quien sos o que queres"); } }); const server = app.listen(app.get('port'), () => console.log('Example app listening on port '+ server.address().port) ); public/css/style.cssbody { background: #fafafa; } img { border-radius: 20px; display: block; max-width: 200px; } views/index.pughtml head title= title link(rel='stylesheet', href='/css/style.css', type='text/css' ) body img(src="/img/logo.jpg") h1= message img(src="/images/foto.png") package.json{ "name": "shadowfiles", "version": "1.0.0", "description": "filter images by session id", "main": "index.js", "scripts": { "test": "echo "Error: no test specified" && exit 1" }, "author": "aloMalbarez", "license": "ISC", "dependencies": { "express": "^4.16.3", "pug": "^2.0.3" } } Out of the example are the handling of errors 404, 500 etc..., charge the style and the logo as static see the difference between posting a folder/ruta with its files and virtualizing another folder/ruta.The UserID I have hardcoded it to 11CCBBAAIf anyone knew the folder to recover foto.png That's it. uploads/UserID and I'd like to get ready by putting the "url" of the user 00AABBCC rising levels:localhost:3000/css/../../uploads/00AABBCC/foto.png Get the mistake:Cannot GET /uploads/00AABBCC/foto.png This can be masked even more by "publishing" a false upload folder, or where public files goconst FAKE_UPLOADS_DIR = __dirname + '/public/uploads/'; app.use('/uploads', express.static(FAKE_UPLOADS_DIR)); It is a basic example, the key is to validate the access to the file and generate the correct path to read it and send it to the browser (in the headers you can send a expire/etag to avoid caches, etc.).The html generated by pug is quite basic I copy it here for reference:<html> <head> <title>Hey</title> <link rel="stylesheet" href="css/style.css" type="text/css"/> </head> <body> <img src="/img/logo.jpg"/> <h1>Hello there!</h1> <img src="/images/foto.png"/> </body> </html>

Access Directory http://xxx.xx.xxx.xx/aa/bb/%E3%81%AE%E3%82%88%E3%81%86%E3%81%AB If you access a URL that does not contain a file name), the following error may occur:You don't have access to this server.1.If no DirectoryIndex is specified in the httpd.config file (files that web server configuration).DirectoryIndex sets the name of the file to be displayed when accessed with a URL that does not contain the file name, and you can set multiple file names.If this is not set, the web server tries to return the directory, but the directory is set to security so that it does not read the contents, so it becomes an error that permission is enabled.2.In the httpd.config file, there is a DirectoryIndex, but there is no file such as index.html.In DirectoryIndex, if the file named index.html is not present in /root/test/laravel/public/, the same error will occur.If 1. is the cause, you can solve it by defining the description of the httpd.config file.2. If the cause is, you can set the file with the correct name in the correct directory.

The operating system uses the dns-servers listed in the file. /etc/resolv.conf in format:nameserver ip-адрес See all the contents of this file, for example, the team:$ cat /etc/resolv.conf to remove only lines starting with nameserver (usually not more than three), for example:$ grep ^nameserver /etc/resolv.conf It is possible to remove only ip-dresses from such lines, for example:$ sed -n 's/^nameserver\s\+//p' /etc/resolv.conf

Summary: using the same password for different things is a generally bad idea. However, in this case, where the two uses of the password control access to the same asset, it's not too bad. So if someone can eavesdrop when you unlock your ssh key (for example by looking over your shoulder, or if they've managed to install a keylogger), they'll know your password on your server. If the only way to log in on that server is to have physical access or through ssh (which has passwords disabled), then having your password compromised doesn't matter. That is, assuming that your password is only a login password. In fact, it is pretty common that your password doubles as an authentication token to become root through sudo. If that's the case, then an attacker who obtains your ssh key file's password as well as the key file can immediately escalate his access to the root account. If you're the only administrator on the server, it doesn't matter much, because the attacker can inject malware into your account that will let him piggyback on the next time you become root. If there are other administrators (or other ways for you to access the root account, such as a remote administration panel), this removes an opportunity for your colleagues to disable your compromised account. Conversely, if someone can find out your password on your server, they can unlock your ssh key file. That's not a concern if you only use that ssh key file (or more generally that password) to access that one server. But if you use the same ssh key for other servers, then the attacker can gain access to these other servers given your key file and that server's password. This only represents a gain if you aren't using that same password on the other servers. All in all, using the same password won't make much difference in typical situations other than a multiple-administrator server where you can sudo to root. Public/private key authentication is more secure than password authentication That's a bit simplistic. Public key authentication uses two factors (the key file and the password to the key file); this is good in that it takes more work for the attacker to compromise both factors. However, you also need to take the risk of a compromise into account. For example, for an ssh key, an active attack on the client will reveal both factors. If the attacker obtains a copy of the key file, he can try to brute force the password offline, so password protection on a key file requires a strong password, stronger than a password that can only be brute-forced through online attacks (though note that an online-only password can be brute-forced offline in some circumstances, for example if the attacker gets hold of a system backup). Using a password for ssh is not wrong per se, if you can guarantee that it's unguessable. Typical users are bad at choosing unguessable passwords, that aren't a simple variation on their birthday or their girlfriend's name. If you have a good password (randomly generated with an amount of entropy that you can evaluate and that satisfies you), it's ok to enable password authentication if you don't type your password in a place where it'll be eavesdropped. So if your login password is only a login password, you might combine an ssh public key for convenience and resistance to shoulder surfing, with a strong password that you don't remember keep in a safe and can use in private in emergencies (such as the loss of your client machine and difficulty to access its backups quickly). If your login password doubles as a sudo password, you will need to remember it. If you only ever keep the key file on an encrypted volume (that only you can access), you don't need to encrypt the key at all. Remember to encrypt backups too.
