Do provide a pass phrase, so your private key is encrypted on disk. With OpenSSH generate yourself a private key with:Īnd follow the prompts. With keys you do get prompted for a pass phrase, but this happens only once per booting your computer, rather than on every connection.
SETTING UP EXPANDRIVE NCSU PASSWORD
If currently you type a password when making an SSH connection, you can make connecting much more pleasant by setting up SSH keys.

Again, it really speeds up copying multiple files a series of git push or scp commands doesn’t require authenticating with the server each time.ĬontrolPersist requires OpenSSH 5.6 or newer. That will cause connections to hang around for 4 hours (or whatever time you specify) after you log out, ready to spring back into life if you request another connection to the same server during that time. This is simply one more line in your config (in addition to the two above for shared connections): If you find yourself making multiple consecutive connections to the same server (you do something on a server, log out, and then a little later connect to it again) then enable persistent connections. If you SSH to a server and then use the scp command to copy a file to it, scp will make use of your existing SSH connection ‒ and in Bash you can even have Tab filename completion on remote files, with theĬonnections are also shared with rsync, git, and any other command which uses SSH for connection.

Shared connections aren’t just a boon with multiple terminal windows they also make copying files to and from remote servers a breeze. If some of these OpenSSH tips sound useful to you, it may be worth giving OpenSSH for Windows a try (or indeed switching to a different operating system .). However, OpenSSH is available for Windows. Some of these productivity features are specific to OpenSSH, so don’t work with other SSH clients, such as Putty. Any tips for making this less tedious would be gratefully received. In such circumstances the only remedy I’ve found on seeing such a message is to exit the connection, rm the file, then connect again. A warning message like this is displayed:ĬontrolSocket /tmp/ssh_mux_dev_22_smylers already exists, disabling multiplexing Then when reconnecting OpenSSH spots the previous file, realizes that it isn’t current, so ignores it and makes a non-shared connection instead.
The second terminal prompt should appear almost instantaneously, and if you were prompted for a password on the first connection (which we need to sort out anyway ‒ keep reading ‒ but it's a convenient way of verifying this shared connection stuff) you won’t be on the second.Īn issue with connection sharing is that sometimes if the connection is abnormally terminated the ControlPath file doesn’t get deleted. Now in a second window, SSH to that same server. Then exit any existing SSH connections, and make a new connection to a server. To enable connection sharing, edit (or create) your personal SSH config, which is stored in the file ~/.ssh/config, and add these lines: ControlMaster auto

OpenSSH is the implementation of SSH that comes with many Unix-liked operating systems, including all the common Linux distributions and Mac OSX. Except sometimes that can seem too much hassle, so we compromise and end up repeatedly cycling through quitting and restarting a few different commands in one window.įortunately OpenSSH has a feature which makes it much snappier to get another terminal on a server you’re already connected to: connection sharing. Often it’s useful to have multiple connections to the same server, for example to edit a file, run some file-system commands, and view a log file all in different terminal windows. If you’d like me to come and talk about this at your user group or workplace, please get in touch. Presented at Yapc Europe 2011 in Riga and theįloss UK Spring 2012 Conference in Edinburgh.
If you regularly use SSH, it’s worth spending a little time learning about these and configuring your environment to make your life easier.
SSH has many features which are helpful when working regularly with files on remote servers together they can give a vast increase in productivity over the bare use of SSH.
