I'm using expect to send commands to my seaside server from within the image:
arguments := { self expectFile fullName. 'ssh'. ipAddress. username. password }. process := PipeableOSProcess command: '/usr/bin/expect' withArguments: arguments.
"Must be non-blocking, or #upToEnd hangs the image" process setNonBlockingOutput.
Where PipeableOSProcess class>>#command: aString withArguments: aCollection
| env pwd desc instance | env := CommandShell new environment. pwd := '/'. desc := (Array with: nil with: nil with: nil). instance := PipeableOSProcess new: aString arguments: aCollection environment: env descriptors: desc workingDir: pwd errorPipelineStream: nil. ^ instance value.
The problem is that I can't easily identify errors because expect delivers commands' stderr onto its stdout. I was wondering if I could do an initial login via expect, setting up to use a security key, and then use regular OSProcess (without expect), but that seems less flexible (would I ALWAYS want to use keys when you SSH? probably not). Any ideas?
Thanks, Sean
