If your console (3270) is logged on to linux (has a command prompt instead of "login:"), you can use the VM msg mechanism to send commands to the linux guest. Two caveats:
1) The console has to be logged on. We solved this by using a patch to the mingetty program. 2) VM translates all commands to upper case, so whatever you run has to be ALL CAPS. We used this to run a "healthcheck" script at intervals, rather than having cron kick it off. It wasn't 100% reliable though, because if the console hangs up for some reason, you don't get any feedback, the msg is just absorbed by the guest. > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Rich Smrcina > Sent: Tuesday, February 01, 2005 10:46 AM > To: [email protected] > Subject: Re: [LINUX-390] z/VM commands to Linux guests? > > > Rexec comes to mind, but there are security issues related to > it's use. > > There are open source packages that can be configured fairly easily to > do this.
