SSH OneShot Lite vs ServerDoor

SSH OneShot is a little iPhone app that lets you store individual ssh commands that you run on your computer or server. The Lite version is limited to two folders to organize your commands, but can be unlocked to unlimited folders with an in-app purchase. What can I use it for? Just about anything you can do on a command line can now be launched from your phone. The different use cases are as follows: Commands These are commands that you launch blindly, without waiting for an results. Examples are for starting and stopping apps and services, or accessing RESTful services via curl that trigger actions. On a Mac you can launch apps in the current open session with something like: osascript -e 'tell application "iTunes" to activate' This can be useful if you have a media server in a closet. Or on a Linux server: service httpd stop Or any other more complex executable script file that you have written. Commands with results These are commands that you launch and want to see the results of. This can be as simple as an “ls” on a directory to see if an ftp upload has finished, a quick service status check or something more complicated like grepping through a log file for errors. Again this can be anything launchable on the command line. There are currently some limitations on the kinds of commands that you can run here. Interactive commands that need to know the terminal type like top, prstat and things like that will not work. Any commands that open an output stream will also not work (but I’m working on for the next release). Status Commands These commands add a little more interactivity. These commands will automatically fire off when you open a folder containing Status Commands and turn the button red or green depending on the results. The basic working mode is that if the command receives anything as a result, that’s good (green) and no response is bad(red). So if you want to check if iTunes is running on the media server you can use the following command: ps ax | grep iTunes | grep -v grep | grep -v iTunesHelper In this example, we take the list of running processes, find all the lines containing the word iTunes (case is important!), and then, using -v eliminate the lines containing grep (which is our initial command) and the same technique to eliminate the line containing the iTunesHelper process that keeps running in the background whether iTunes is running or not. So if iTunes is running, we will get back a line from the original request, otherwise the result will be empty. If you are having difficulty phrasing the command so that empty is bad, you can flip a switch to swap that part around. For example I check the results of my ZFS server with zpool status and look for the word “degraded” which means there’s a disk offline that I need to check on. zpool status | grep degraded With the “Null return is good” switch turned on. Is it secure ? Passwords are stored in the iOS keychain, and all network communication is via SSH, so, well, yes. Navigation Press and hold a command or a folder and you can reorder it, file it in a folder, or use the edit and delete buttons at the bottom of the screen.

ServerDoor allows you to use your smartphone like a secure door for remote access to your personal server. A user-friendly session manager with a simple and intuitive interface, a full-featured terminal emulator that supports gesture control, as well as a tool for working with SSH keys - now all those thing can be placed in your pocket. Connect to your servers with using telnet and ssh protocols to administrate them in any situation anytime. Main advantages and functions: -The tool for working with SSH keys allows you to generate them, as well as to import and export them. RSA, DSA, EC, ED25519 keys are supported, and the openssh-key-v1 format is used to store them. -Thanks to the built-in password manager, you do not have to keep in mind the passwords for each server and key. The password database is stored on the device and encrypted with AES256-CBC using the master key. You can manage the password manager or disable it altogether in the settings. -Snippets system will be useful for advanced shell admins and can be used for make scripts those you can call from terminal session anytime. -Export and import app data features allows you exchange data between different devices or make backups anytime. -Convenient gesture control makes it possible to change the font size in the terminal by simply stretching instead of constantly switching to settings, and sticky scrolling allows you to quickly navigate even in the most voluminous sessions. • Advanced terminal emulator, supports most ESC sequences, SGR and utf8 encoding. • Additional keyboard and hot buttons, allow you to use most commands and keyboard shortcuts, as well as emulate mouse clicks in terminal applications. -Supports simultaneous operation of an unlimited number of running sessions, including in the background, when the application is minimized. -The ability to manually set a limit on the number of lines stored for each session (or disable the limit altogether), allows you to flexibly configure the device's memory consumption by running sessions. Whether you want to store the whole session or set a hard limit to save memory is up to you. -To save memory, session data is compressed and stored in a fragmented way, which allows you to turn off the limit and store even the most voluminous sessions without large buffer allocation errors. Tired of Telnet clients cutting HTTP responses without even allowing you to view the header? Then this app is for you!
