Ssh – Using ssh with single command to execute remote binary

bashssh

I want to start a binary on Machine A from Machine B and wait for it to exit.

Machine B runs the following script:

ssh user@machineA bash -ic /bin/something

bash then aborts with cannot execute binary file: Exec format error.

The binary runs correctly if executed directly on Machine A.

How do I solve that?

The problem is not with ssh.

You are trying to run an executable compiled for a different architecture than Machine B is.

If you run file on the binary, it should tell you what architecture it is compiled for

You could either get(or compile) a binary that works for Machine B's architecture, or try to get some kind of emulator.

Without the kind of binary it is, I can't give any recommendations

You want to use expect for this. It's probably already on your machine. It's the standard tool for any kind of interactive command-line automation. It's a Tcl library, so you'll get some Tcl skills along the way for free. Beware; it's addictive.

#!/path/to/expect
spawn ssh user@example.com "mysql -u blub"
expect "*ssword:*"
send -- "mypass\r"
