Package: munin-node
Version: 1.2.2-2
Severity: normal
Hi,
I have a /etc/munin/plugin-conf.d/entropy file which reads:
[entropy]
user root
group proc
Originally it just had "group proc", because:
dr-xr-x--- 11 root proc 0 Mar 15 09:10 /proc/sys
(/proc/sys is only accessible to root and to group proc on my ststem).
I recently noticed that this no longer worked; the entropy plugin couldn't
read the entropy_avail file. I added an 'id' command to the plugin, and
noticed the following:
# telnet localhost 4949
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
# munin node at name-of-box
fetch entropy
#uid=0(root) gid=183(munin) groups=183(munin)
entropy.value 16814
.
Note how it is not a member of the "proc" group. The situation is the same
if I remove "user root" (obviously it runs as a different uid then, but
still no group proc). Naturally, a large number of other plugins are
affected as well.
This used to work before and got broken recently. Alas, I can't say exactly
when.
