What rkhunter is telling you here is that it is unable to unhide the process because your system is lacking an application, "unhide" and "unhide-tcp". Install it first with : #pacman -S unhide unhide-tcp #to install unhide and unhide-tcp, forensic tools

Running rkhunter this time it gave me this bit of warning.

dhcpcd and wpa_supplicant are valid services obviously. So to whitelist these processes in /etc/rkhunter.conf all I did was to remove the #.

file-/etc/rkhunter.conf starts
[partial starts]
# Allow the specified process to listen on any network interface.
#
# This option may be specified more than once, and may use wildcard characters.
#
# The default value is the null string.
#
#ALLOWPROCLISTEN=/sbin/dhclient
ALLOWPROCLISTEN=/usr/bin/dhcpcd
ALLOWPROCLISTEN=/usr/bin/wpa_supplicant
#ALLOWPROCLISTEN=/usr/sbin/tcpdump
#ALLOWPROCLISTEN=/usr/sbin/snort-plain

file-/etc/rkhunter.conf ends

Running rkhunter again I get this non-warnings.

Important: After modifying /etc/rkhunter.conf run #rkhunter -C to check the config file.

Appindicator In Natty Ubuntu 11.04

Previously ranted about the blind alley Ubuntu 11.04 seemed to be leading us when it comes to some applications not being ready yet for the dropping of system tray.  What I should have done is press on. There are posts about editing a white list with a recommended GUI tool to help us out here , here and here . Like everything in Linux, there's a configuration file for it, if you can find it and if you have the inclination to go ninja. If not then there's dconf-editor. Download dconf-tools from Software Center. Navigate to desktop>unity>panel. Add your application in the white list. Then close the window. No save button. mmm. So far I have added Shutter, Dropbox and Keepassx in the white list.                Before...  After.

Evolution Mail on GNOME 3.26

There's a slight change in the user interface. A To Do column now appears to the rightmost after the GNOME 3.26 update. Also there's a noticeable stability increase, what with goa-daemon stopping its RAM usage creep. I don't have to kill it every couple of hours.

New Converge ICT Plan Max with Sky Now

I pulled the trigger on Converge Max plan 400Mbps with Sky channels. I went to their sales office and asked for the upgrade. No charge at all and they didn't ask me to return the old modem. It looks like they will pull it when they install the new modem.e     It came with a black box for the TV. The configuration is easy but it took me 3 days to figure out the Wired connection. It should be fine except I have to jiggle it in the config (GUI). Turn 802.1x  on and off to finally connect.  Here's the speed for the Wired connection:
