fprintd errors in Virtual environment

JakesHat · 11-23-2011, 06:18 AM

Every time a user uses su I get the following error messages in /var/log/messages:

Code:

I have a few physical servers and a few virtual servers all running RHEL 6.1. All of the servers were installed the same way with the same packages, but I'm only receiving these messages on the virtual servers.

I've searched google, and found a few answers, but nothing I have been able to use. From what I understand the fprintd daemon is used for a fingerprint reader which I have no use for on my virtual servers.

One solution I read on another site stated

Quote:

fprintd is a daemon that allows the function of libfprint over DBUS. Which is to support fingerprint scanner authentication. I am assuming that your vm does not have a fingerprint scanner so this is probably not a big deal for you. If you want the errors to quit I would remove fprintd unless you plan to use fingerprint scanning

Can someone tell me how to remove fprintd or some other way to get these messages to stop? Thanks in advance

really??? 78 views and no help? I don't think this is too complex, someone should be able to tell me how to stop this daemon. On a test system I tried rpm -e on the fprintd packages I saw but it wouldn't let it uninstall because of dependencies.

112 views, and still no answers? I can't be the only one with this problem... this is a default install of RHEL 6.1 in VMware. Anybody??

Just ran into the problem myself. run 'authconfig' and disable 'finger print reader'.

I finally got it figured out too. I was able to remove it... I think it was yum that I used to remove it.

I had a similar problem on a virtual Centos 6.1 server which I resolved with:
yum remove fprintd libfprint

Same problem on CentOS 6.2 virtual machine on WS2008R2/Hyper-V

I'm running RHEL 6.2 in a VMWare environment:

yum remove fprintd libfprint

also resolved my core dump issues.

jescala · 03-01-2012, 09:30 AM

I also had the problem with RHEL 6.2 running on a VM on ESX. Apparently authentication via a fingerprint reader is enabled by default in RHEL 6 and this somehow causes problems in a virtual environment. You can confirm that it is enabled by running:

Code:

# grep -i fprintd /etc/sysconfig/authconfig
USEFPRINTD=yes

I was able to disable it by running this command:

Code:

# authconfig --disablefingerprint --update

Another grep confirms it:

Code:

# grep -i fprintd /etc/sysconfig/authconfig
USEFPRINTD=no

Thanks roger_efn for the post that helped me find the solution!

Nice to see a different solution

I think I would still opt for removing it completely... if we're never going to use it, why even keep it installed.

Considering everything seems to be going virtual now, maybe Red Hat should be informed about this so they can by default have it disabled in future releases.
