Somehow, though, I ran into this answer from Pistos on StackExchange. I found an older post with a suggested change to the DNS settings in /etc/ssh/sshd_config, but that didn’t help because the change had already been made in more recent versions of macOS. When I decided to try to fix this annoyance, my working assumption was that there was something in the SSH server configuration causing the hiccups. That the web server is halfway across the country makes it all the more frustrating when I have a choppy terminal session to the Mac that’s no more than 20 feet away from me. When I log into the Linux box that hosts this blog, both terminal programs are smoothly responsive. This is not a bug in Prompt or Textastic. I often just don’t know where the cursor is on the Mac because it’s not necessarily where I see it on the iPad. This leads to typos that take a while to correct because repetition on the ⌫ key also outruns the display. I am by no means a fast typist, but I regularly get ahead of the display. The most common key I use is ↑ to rerun the last command.īut when I do need to construct and run longer commands, I’ve noticed a lag between the keyboard and the screen. The responsiveness of the SSH connection to the Mac isn’t important to my productivity. Since a lot of the terminal work I do isn’t complex, and consists of repeated invocations of pdflatex report Running commands is done through either Textastic’s internal terminal, which works well enough for simple stuff, or Prompt, which has more robust terminal emulation and is better for more complex sessions. Editing files is done in Textastic and synced to the Mac through iCloud (used to be through Dropbox). A lot of the work I do “on” my iPad consists of me essentially using the iPad as a terminal to edit files and run commands on one of my iMacs.

Disabling hardware via kernel extensions.To redirect a remote port to a local or remote host port: To redirect a local port to a remote host port: Only root can forward privileged ports (<=1024) SSH can port forward local and remote connections securely. It is usually more convenient to run ssh-agent and load keys in a BASH login. To load secret keys in the ssh-agent manually, execute: To bypass the passphrase that unlocks your secret key every time it is needed, load the key into ssh-agent. Next, append the v2 public key to your $HOME/.ssh/authorized_keys2 file on the server(s) where you want to login. The system will prompt you for a secret key passphrase, then create the key pair in two files: Scp localfile Using public/private key encryption for authenticationįirst, generate a keypair for logins without passwords: Scp localfile securely copy remote file(s) to the local machine, use scp: Ssh securely copy a local file(s) to a remote server, use scp: To connect to an SSH server using a different user ID: The user configuration file, $HOME/.ssh/config takes precedence over the default configuration. The default client configuration file is: If you copy personal SSH files to a new system and they don't work, check the permissions. For example, the file permissions should look like this: Note: because of its sensitive nature, the $HOME/.ssh/ directory and most of the files in it MUST be read/write for the user and not accessible to group or other.

To disable keyboard password logins (force public/private key authentication), set this value in the sshd_config file: To disable X forwading, set this value in the sshd_config file: To disable the less secure v1 SSH protocol, set this value in the sshd_config file: private/etc/sshd_config To deny all remote SSH root logins (generally a good idea), set this value in the sshd_config file: SSH communicates over TCP port 22 by default.
