编辑：要澄清这里，我对来自终端的脚本不感兴趣。我要做的是以自动/计划方式运行SSH命令。 tasker和locale执行是Cron的等同器，我只需要的是'ssh'命令从 脚本运行 。
I of course have ConnectBot, but I'm looking for something I can script.
Edit: To clarify here, I'm not interested in running scripts from a terminal. What I want to do is run an SSH command in an automated/scheduled manner. Tasker and Locale Execute are the equivalent of cron, all I need is the 'ssh' command to run from the script.
You can install the Terminal Emulator from google. Alternatively there is the Better Terminal Emulator Pro. I tried the Terminal Emulator on a non-rooted phone and it seemed to work fine.
Better Terminal Emulator Pro includes the dropbear ssh client, which can be launched from the command line or via a launcher. More info from the authors.
Since my original question was about an ssh binary, and there is an answer for that, I'll accept that answer. However, there is another way to do what I wanted to do, kinda, that might be interesting to someone some day.
Tasker + ConnectBot can be used to execute arbitrary remote (or local, I guess, but Locale Execute is better for that) commands on a schedule.
Step 1: Set up your connection in ConnectBot.
Step 2: Create a Tasker Task to call connectbot.
Step 3: Use this Task in Tasker however you would normally.
I know it's an old thread but wanted to +1 the comment about BTEP
I'm also using BTEP's ssh binary though I just call it from it's path instead of linking it /data/data/com.magicandroidapps.bettertermpro/bin/ssh email@example.com
or generate a pair of keys and use public key authentication /data/data/com.magicandroidapps.bettertermpro/bin/ssh -i /data/data/com.magicandroidapps.bettertermpro/home/.ssh/id_rsa -l root 192.168.1.1
I use the above command from SL4A r4 in various scripts and it works fine :)
before I could do this I needed to chmod a+x /data/data/com.magicandroidapps.bettertermpro/home/.ssh
once this is done and you backup/restore BTEP with TitaniumBackup the permissions are kept this means if you flash a new rom you can just restore the apps and all your scripts will work again
I have successfully used BotBrew Basil Experimental when running Android 4.4. BotBrew Basil Experimental is based on apt-get so after installing APK and bootstraping I just did
apt-get install dropbear in a root shell to install SSH client (and server).
Install terminal emulator and quickssh. Quickssh also includes dropbear. Does not cost you money, which it should not because this is surpassingly simple and it's based on dropbear.
find -name ssh user@host
Terminal Emulator absolutely supports scripts*. Don't believe the nay-sayers. You will need to learn BASH shell scripting, if you're not already familiar with it. Write a script and save it on your SD card. Run it with "sh filename" from Term.
If you clarify what it is you want to "script" having to do with SSH, I can likely give you a better recommendation.
*(It's actually the Android OS that supports BASH scripts, Terminal Emulator just grants you access to the Android shell, therefore scripting is inherently possible)
To call ssh from a script, all you need to do is set up ssh keys. There are a million how-tos on the web, but there's a page on the Cyanogen wiki that might be more suited to Android users. Once you set up keys, your general ssh command would look something like this: ssh -i /PATH/TO/KEY USER@IP
You can put that in a script, run it, and you will be logged in to the remote machine.
But here's what I think you're wanting to do. To only execute a command on a remote computer, just add it in single quotes: ssh -i /PATH/TO/KEY USER@IP 'command'
That executes the command on the remote machine without logging you in. You can run commands with options, pipes, redirects etc, but it's sometimes better to keep them simple. Except for the delay, it looks the same as executing the command(s) locally and can be used the same.
Locale Execute can be picky about what commands it will run. If it doesn't work, try putting it in a script and using Locale Execute to run the script.
Also, I have had problems with the ssh binary that is on the phone and found that moving it from /system/xbin and creating a link at /system/xbin/ssh to the Better Terminal Emulator ssh binary is more reliable. The BTEP binary is in /data/data/com.magicandroidapps.bettertermpro/bin/ssh
Botbrew is a package manager for Android, in the likes of
okpg for BSD or more recently, like
APT for Debian. Pretty nice. It doesn't have an ssh client as a package, but it doesn't look too hard to put in if you're used to building your own packages. And it could be useful as a toolchain for when you want to build other C/C++/etc binaries and libraries.
So albeit this isn't a direct answer, it may be useful for some people to know about.
Now there is a terminal called Termux that you can apt install openssh in. Available on Google Play Store, F-Droid, and Github.
AndFTP can connect over any port you configure so I'm sure it could connect over SSH. But I'm not sure how easy it is to script usage of it. I use the app myself all the time for my hosting server and it works great.
Not sure if you can SSH with Terminal Emulator, but you could try it too. I use that app frequently for doing things I'm too lazy to do with ADB.
Use an ssh plugin for Tasker? Don't need root or ssh binary then.
If the simple ssh client is interesting to you, I made under Android-NDK Bionic library drobpear-ssh-client-only. ftp://ftp.simtreas.ru/pub/my/dropbear/dropbear-ssh-only.tgz sourse and ftp://ftp.simtreas.ru/pub/my/dropbear/ssh binary
