[Nut-upsdev] Good news

[john hart]

Tim,
The owner is root and the group is tty .  However, my problem is the following.  When I check mesg in a terminal I get this:
john at debian:~$ mesgis yjohn at debian:~$ 
However, from another terminal (as root) I get this:
root at debian:/home/john# write johnwrite: john has messages disabledroot at debian:/home/john# 
How can it say 'mesg is y' and yet say that messages are disabled ?  I think I need to contact the Debian usersforum.  It's a bit too strange for me.
And what is strange is that when I have the NUT-Monitor running, wall appears to work.  It may well be somekind of permissions issue.  I will take it up with the Debian forum before I try changing the permissions.
John

ls -lia /<path>/wall will give you the owner and group . . . . 

Messages off . . . I think you are on the path . . . .

Time, not sure who owner is, but I've tried as both admin and myself, to no avail.  However, I told you that mesg is y, buti tried to send a mesg using  ' write '  and it says I have messages disabled. ?????   I did that by opening two terminals, on I logged in as ' su ', and sent the message from there.  Is that peculiar? Might account for why I am notgetting anything from ' wall ' .

Who is the owner and group for wall? Note that it is set group ID to allow it to write to sessions . . . thus, that owner needs to be a system account that can write to devices, not just Joe-Bob . . . You might also try 'strace wall' to see what it is trying to do.

Tim,
Thanks for the feedback.  I am the only user (standalone system), but I checked 'mesg' and made sure it was set to 'mesg y' .   And the execute permissions for wall are   rwxr-sr-x  and the filename is has a  kind of orange highlightedbackground. Don't know what that means.!

Any chance someone put 'mesg n' in the system profiles? That wou;d suppress wall output. Try typing just 'mesg' and see what it says . . . otherwise, check permissions ! on wallperhaps . . .

Tried 'echo hi | wall' and no message.  I looked at 'wall -h' and it would seem that it is supposed to.  I eventried  ' wall  [<filename> | <message>] '  and got nothing.   Not sure what that means, as when using theNUT-Monitor program I get banners and a 'message' on the system try.   Strange !

Good to hear!

Not sure if you mentioned, but if you run something like "echo hi | wall", does it broadcast a message? If not, I'd say that's a bug in wall, but you could configure upsmon to run a different program to send a message.
