The initial sshfs command mounts the user's home directory to remote-home. Let's look at a very short demonstration. The benefits are the inherit security and that it is easy to setup. For instance, multiple users writing to the same file at once can create havoc. As a remote file access protocol, sshfs is not very good. The sshfs is implemented using FUSE, and relies on the sftp part of ssh to access the remote computer. Before we look into how, let's have a quick look at sshfs. What sshfs does is that it exposes this functionality as a file system that you can mount. These two commands means that you can browse the file system, and freely copy files between machines. not in the home directory of user, to your local machine. The command below demonstrates how to copy a file with an absolute path, i.e. You can copy the other way around as well. To copy the file test.txt to user's remote home directory, simply enter: $ scp test.txt :Īs before, you will be prompted for a password. The handy scp command, secure copy, works in much the same way. Having entered the password, you should now have full access to the remote system. Now, you should be able to log onto your machine using your normal user credentials. For external access, you also need to enable port forwarding of port 22 in your router/firewall and find your external IP. In Ubuntu, that means the openssh-server package. To get things up and running, what you need to do is to install sshd. There are many guides on hardening servers and ssh, so I will not go into details. You might also want to tune your hosts.allow and ny files if you plan to expose sshd to the Internet. The notion is that the more limits you put on the remote access, the more secure your system is from potential attacks. ![]() Here, you can disable root access, older protocols, X11 forwarding, etc. You can configure sshd through the /etc/ssh/sshd_config file (that is the location on my Kubuntu machine). graphical, programs on the remote machine and displaying the windows on the terminal that you are sitting at. With the -Y flag, you can even run X11-forwarding, allowing you to run X11, i.e. It makes it possible to run an encrypted shell session. The secure shell daemon runs on port 22 by default. All that you need is to enable the secure shell daemon - sshd.īefore we go into the details of the sshfs, let's run through a quick re-cap of ssh. Being able to move files between machines without having to setup SAMBA or NFS is very handy when working with multiple systems. There are two choices for GNU Emacs on Mac OS X: Aquamacs and the more vanilla Emacs for Mac OS X, both are built from FSF GNU Emacs.The secure shell, ssh, and its companion, scp, are tools that I use more or less on a daily basis. What is GitHub? If you are like me and have very little experience with computers, aside from email, then you probably don’t know what GitHub is. Install Aquamacs as directed, then start it. In Aquamacs, press the keys Control-X Control-F. Aquamacs: /Library/Preferences/Aquamacs Emacs/Preferences.el Regular emacs on Linux or OS X: /. I found this post to be very helpful in explaining what it is and why we would care to use it. In short, GitHub is a version control system, it is open source, user-friendly, and we need it for our summer project.Ĭlear and easy to follow directions on how to set up an account and get started are available on Anton’s wiki. Once you create an account, you would want to go to your settings and then choose the SSH and GPG Keys link from the left-hand tab (see below). Emacs is installed on macOS by default, but a very old version, version 22.1, dated 2007. Next, you would need to generate an SSH Key, following the instructions here. In terminal, type: which emacs check if emacs is installed and in your path. (to quit, press Ctrl+x Ctrl+c) Download Latest Emacs for MacOS. A link to these is also available on Anton’s wiki. Once you have completed this part, open Aquamacs, if you are working on MacOSX, or Emacs for Windows OS. Find/open the file named init.m2 in Aquamacs or Emacs you can reference this post on where to look for the initialization file. Once you have located the initialization file, you would want to redirect the path highlighted in the screenshot below. This allows you to pull the Macaulay2 packages from the repository you cloned from GitHub.
