Hi, Looking the 'help' output of mconsole_uml I've discovered the following:
exec <command> - runs the specified command through /bin/sh -c This is a wonderfull feature! I wonder when it was included (old versions of uml_mconsole doesn't include it, and even the documentation in http://user-mode-linux.sourceforge.net/mconsole.html seems to be outdated). For reference: my uml_mconsole is the one that comes with Debian pacakge uml-utilities version 20040406-1. However, I've tried to use the feature: (/root/.vnum) exec "echo hello > /tmp/foo" OK The command has been started successfully. but, in spite of the message, it seems not being working because the file "foo" doesn't get created in the virtual machine filesystem. Googling for "uml_mconsole exec", I found the following at http://www.user-mode-linux.org/~blaisorblade/faq.html: "What's Mconsole exec? It adds the "exec" command to uml_mconsole; it allows you to start an arbitrary command through mconsole. It will be passed to /bin/sh -c, so you have all the shell power at hand. It must be enabled when compiling the kernel (because you might not want to allow this to the host admin)." Reading that, I think that the problem could be my UML kernel is not compiled with the propeer enabling configuration option. What should I look for in the './linux --showconfig' to check it? Or maybe I'm using a wrong syntaxis (for example, the quotes that encloses the echo command are hurting)? Any information regarding uml_mconsole exec is really welcome. Thank is advance!
