![]() It is designed to minimize the risk of data theft or exposure from lost or stolen computers. When activated, it will encrypt the contents of the hard drives in Windows, making the data inaccessible without the correct decryption key. How about you? Did you like Mosh or do you still prefer SSH? Do share your views.BitLocker Drive Encryption is a data protection feature that integrates with the Windows operating system. Ever since I discovered Mosh, I have stopped using ssh for connecting to remote servers. Now for realizing the power of mosh, try turning your network connection off and on again. You just need to pass the “ ssh option ” to the option –ssh.įor example, I need to connect to ssh running at port 2222 on the remote server. It is that simple just like ssh.īut what if I need to specify the ssh port other than the default port or to use ssh specific options. sudo ufw allow 60000:61000/udp Let’s connect through moshĪs of now, we have a working SSH, mosh that is installed in both systems, and a firewall rule that allows UDP traffic on ports 60K-61K at the remote server. So if you have a firewall on the remote system, you must rewrite the firewall rule for those ports as follows. Remember the part that I said mosh uses UDP? By default, mosh uses UDP ports 60000-61000. server), you have to do a simple configuration. Use the package manager of your distribution to install it.Īfter you are done installing mosh, everything is ready on the client/local side. Mosh is available in all major Linux distributions. ![]() To install mosh in Ubuntu or Debian based Linux distributions, you may use the following commands, one by one: sudo apt update The package you need to install is the same in both local and remote systems. If you don’t have ssh installed and configured, please learn the basics of SSH and enable SSH on Ubuntu or whatever Linux you are using.Īfter ensuring you have a working SSH setup, installing mosh is a straight forward task. Install mosh on Ubuntu and other Linux distribution It also implies that you should have a working SSH setup both in the local and remote system. So every security advantage that ssh has is also with mosh. So you need not create new key pairs or users and the like. To avoid reinventing the wheel, mosh uses ssh for authentication. To know how mosh works, read its official page. And to transmit packets, it uses UDP which is connection-less protocol. It uses a technique similar to buffering and synchronization of items (objects) using SSP protocol (state-Synchronization Protocol). It gives a simple solution to all the problems mentioned above. You know what’s better? Mosh! Mosh: SSH without the connectivity issues Mosh is better than SSH You may use the nohup command in Linux to continue running the commands even after SSH connection drops out, but it’s not really a good solution. To summarize, SSH provided great security but little usability in high latency connections. When you are inactive for a long period, sometimes SSH will stop working even though your computer weren’t idle and network connection was active.The characters you type in the local system may appear after seconds, or in worse cases, even minutes. When you have a slow internet connection, the same situation will arise.And then you will check the internet/Wi-fi icon. ![]() When you type in the shell, you will notice that nothing is happening. Your network connection is disconnected.You might have had frustration with ssh in one of the below situations. It’s not the typical frozen Linux system, just a frozen terminal with the disconnected SSH connection. TCP connection will be broken and the local system will be left hanging in the air without any error. “”” It just sends/receives encrypted packets“””īut what happens when the network is disconnected or is very slow. Even the characters you type are sent to the remote system and then the remote system sends its response (which contains the character typed to be displayed on the screen) to the local system.Ĭan you see that whole round trip to see a single character you typed ? There is no buffering and processing in the middle. SSH sends the packets between the local and remote system just like telnet but the contents of the packet are encrypted. To put working of ssh in simple terms, it is a TCP connection of encrypted packets. It allows user to communicate with the remote system without any fear of eavesdropping or tampering. The main advantage of SSH is its encryption. SSH allows users to login into remote systems with/without password but with the help of a private key and a public key. Due to the severe security vulnerabilities of telnet, it was replaced by ssh. To login into a remote system, we used to use telnet.
