I'm working as assistant sysadmin on our local net of RS6000s. We have three 320s (2 with 8Meg RAM, one with 16) and four Xstation 120s. We are runing AIX 3.1.1 on these puppies. I have two big problems with things that happen on them. The 16 Megger monitors the logins on the four Xstations and also holds the nfs mounted /u partition. 1) A user is plugging away happily at the console and the console locks up. No mouse movement, no response to the keyboard, NOTHING. How can I reset the terminal from a remote location without rebooting the offending machine. Killing off alll the user processes doesn't help at all. If the terminal cannot be reset without rebooting, is there a way to reboot without having to insert the key to the machine (I'd like to be able to handle these minor emergencies from home). 2) Something that happens to me a lot but doesn't seem to trouble anybody else: I log in from an Xstation and start up (in this order) mwm, xclock, aixterm -v, aixterm -v. I plug away happily and mwm stops. An error message appears on the "login" window saying [1] mwm stopped (tty output) This just doesn't make any sense to me at all. An icon for mwm appears in the upper right corner but it cannot be restarted by clicking on it (duhhh the window manager isn't paying attention). The only way that I've been able to restart it is by 'kill -HUP'. And that only works about half the time (sometimes it'll show the "Exit mwm ?" screen and stop again when I click "cancel" (or no, or whatever it is), sometimes it'll show the "Exit mwm ?" screen and restart fine, sometimes it just diescompletely). If it is the second "HUP" signal that I've had to send, it _always_ dies. Any clues on these little annoyances? TFM doesn't seem to help much... I've looked, but not too closely.

Once in a while the X server running on the console seems to freeze (mouse dead too), and nothing short of a reboot seems to help. Killing mwm does no good at all.

Try the following command to clear the console, typically the user has no processes going; tput -Thft clear > /dev/hft This command has saved me a lot of reboots. -- Dale A.
