Good evening,
I don't know if these are properly rkhunter questions, yum questions,
or F-20
questions,
so I'm posting to both lists.
Last Monday, I updated my 64-bit system from Fedora-19 to Fedora-20.
Several
minutes ago,
I updated Fedora-20 by doing "yum update". I then did
"rkhunter
--update", and then
"rkhunter --check". I'm getting a lot of issues.
1. I get these messages in the rkhunter log:
[18:55:34] Info: The command 'rpm -qf --queryformat...
/usr/sbin/chkconfig' gave error code 1.
[18:55:39] Info: The command 'rpm -qf --queryformat...
/usr/sbin/fuser' gave error code 1.

[18:55:55] Info: The command 'rpm -qf --queryformat...

[18:56:01] Info: The command 'rpm -qf --queryformat...
/usr/bin/rpm'
gave error code 1.
[18:56:01] Info: The command 'rpm -qf --queryformat...
/usr/bin/sed'
gave error code 1.
[18:56:07] Info: The command 'rpm -qf --queryformat...
/usr/bin/mailx' gave error code 1.
I get these warnings a lot (both under F-19, and since updating to
F-20).
What's causing
these warnings? Is there something yum should be doing, but
isn't?
Is there something I
should be doing, but I don't know it?
I wrongly believed these all to be packages. So these messages do not
really signify a problem, either with my system or with yum.
2. I get this warning in the rkhunter log:
[18:55:49] /usr/bin/curl [ Warning ]
[18:55:49] Warning: Package manager verification has failed:
[18:55:49] File: /usr/bin/curl
[18:55:49] Try running the command 'prelink /usr/bin/curl'
to
resolve dependency errors.
[18:55:49] The file hash value has changed
[18:55:49] The file size has changed
The warning gives me the immediate fix, and it works. But the
problem recurs
after almost
every "yum update" (both under F-19, and since updating to
F-20),
though not on the same
packages each time. What's the real problem? Is there something
yum
should be doing, but
isn't? Is there something I should be doing, but I don't
know it?
Since I'm doing things manually, I just need to do a "prelink -qa" after
the "yum update" is done but before running rkhunter. No yum deficiency
here.
3. Since updating to F-20, I'm seeing this warning:
[18:56:18]
[18:56:18] Checking for GasKit Rootkit...
[18:56:18] Checking for file '/dev/dev/gaskit/sshd/sshdd' [ Not

[18:56:18] Warning: GasKit Rootkit [
Warning ]
[18:56:18] Directory '/dev/dev' found
[18:56:18]
The directory "/dev/dev/" contains one entry:
bash.6[dev]: ll
total 0
lrwxrwxrwx. 1 root root 10 Jan 29 13:48 resume -> ../../sda5
bash.7[dev]:
Doing "file resume" gives this:
bash.21[dev]: file resume
resume: broken symbolic link to `../../sda5'
bash.22[dev]:
I see no "sda5" in the root directory. A "df" shows no filesystem. An
"ls -a" of the root
directory shows one file I did not expect:
-rw-r--r--. 1 root root 178665 Jan 29 18:50 .readahead
It seems to be binary.
Do I have a security problem? What are "/dev/dev/resume" and
"/.readahead"?
This is a false positive. Someone else already recognized the problem
and submitted a bugzilla. The "/.readahead" file is not a problem.
thanks,
Bill.
I thank everyone who tried to help for their time, effort, and patience.
