reopen 334105
thanks
Hi Karl,
2007/3/6, Karl Schmidt <[EMAIL PROTECTED]>:
Subject: nut: /dev/ttySx permissions
Package: nut
Version: 2.0.5-3
Severity: normal
-- System Information:
Debian Release: 4.0
APT prefers testing
APT policy: (500, 'testing')
Architecture: amd64 (x86_64)
Shell: /bin/sh linked to /bin/bash
Kernel: Linux 2.6.18-3-amd64
Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8)
I can change the permissions of /dev/ttyS1 and get things working - but on the
next reboot
it again has the wrong permissions set by udev.
crw-rw---- 1 root dialout 4, 65 2007-03-05 22:22 ttyS1
I can think of several ways to fix this - but it seems to me the best would be
to have the
nut user be a member of dialout?
At the very least there should be something in the docs so uses fix the
permissions in a
consistent way.
As per the /usr/share/doc/nut/README.Debian.gz file, ยง2:
(2) serial port permissions
The nut user need to be added to the dialout group for the serial
communication to work. The following command accomplishes this:
addgroup nut dialout
This is not done by default for security reason.
I may also add something like in http://bugs.debian.org/334105:
Place this in /etc/nut/rules.d/01-ups.rules or something:
KERNEL="ttyS15", GROUP="nut"
where '15' is your serial port.
So it belongs to #334105, which I've reopened to track this issue.
I will complete the doc with the next update.
thanks,
Arnaud
