[Bug 537851] Re: dhclient silently ignores unreadable config-file
I can confirm this issue. I have reproduced the problem and used strace.
I've also found the app-armour log entry. The app-armour disallowing the
-cf is presumably intentional. The bug is that dhclient3
does not warn the user or log an error when it's unable to open the file
parsed to -cf.
In trace-cust-dhcpclient.log:
open("/home//Scripts/reroute/dhclient-cust-sbsa.conf", O_RDONLY)
= -1 EACCES (Permission denied)
In kern.log
Nov 7 17:09:18 kernel: [20777.329386] type=1400
audit(1320678558.977:25): apparmor="DENIED" operation="open" parent=8316
profile="/sbin/dhclient3" name="/home//Scripts/reroute/dhclient-
cust-sbsa.conf" pid=8317 comm="dhclient" requested_mask="r"
denied_mask="r" fsuid=0 ouid=1000
The trace was produced as follows: sudo strace -e trace=file dhclient -e
IF_METRIC=0 -cf /home/enigma/Scripts/reroute/dhclient-cust-sbsa.conf
usb0 &> trace-cust-dhcpclient.log
