Title:
File "dhclient.conf" cannot be read.
Status in “linux” package in Ubuntu:
Invalid
Bug description:
Release info:
:/etc# lsb_release -rd
Description: Ubuntu 10.04 LTS
Release: 10.04
Package info:
:/etc# dhclient -v
Internet Systems Consortium DHCP Client V3.1.3
Copyright 2004-2009 Internet Systems Consortium.
What I expected to happen:
Logged in as root, use "less" or "cat" to review the contents of the "/etc/dhclient.conf" file.
What actually happened:
Logged in as root, I could not directly see the /etc/dhclient.conf file in an "ls" listing and I could not view the contents of the file.
The file "/etc/dhclient.conf" will appear in a listing "ls -al
/etc/dh*" as follows (all commands run as root):
:/etc# ls -al dh*
total 28
drwxr-xr-x 4 root root 4096 2010-04-30 15:47 .
drwxr-xr-x 156 root root 12288 2010-05-23 12:05 ..
-rw-r--r-- 1 root root 1716 2009-10-08 18:51 dhclient.conf
drwxr-xr-x 2 root root 4096 2010-04-30 15:48 dhclient-enter-hooks.d
drwxr-xr-x 2 root root 4096 2010-04-30 15:48 dhclient-exit-hooks.d
However, this file will NOT appear in a listing "ls -al
/etc/dhclient.conf":
:/etc# ls -al /etc/dhclient.conf
ls: cannot access /etc/dhclient.conf: No such file or directory
Any attempt to cat or less the file /etc/dhclient.conf results in
failure:
:/etc# cat /etc/dhclient.conf
cat: /etc/dhclient.conf: No such file or directory
:/etc# less /etc/dhclient.conf
/etc/dhclient.conf: No such file or directory
This behaviour was noticed on a Lucid Lynx system, and a rootkit was
suspected. However, this was repeated on a Lucid Lynx "live cd
session" so it is clearly not a result of an intrusion.
Looking for "dhclient" in lsof output produced the following which
includes no listing for the dhclient.conf file:
:/etc# lsof | grep "dhclient"
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/john/.gvfs
