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
[partial ends]
file-/etc/rkhunter.conf ends

Running rkhunter again I get this non-warnings.

logfile-/var/log/rkhunter.log starts

[20:00:49] Info: Found process '/usr/bin/wpa_supplicant': it is whitelisted.

logfile-/var/log/rkhunter.log ends

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

Password Issues On Ubuntu Login

I found myself unable to enter my login credentials when prompted to do so in Ubuntu. I think I might have changed it then forget about it. I've been running the current session for more days than I should have. I forget. So what's the solution to my problem. How do I get in to my system now? It involved getting into the grub menu somehow. I am uncertain as to how to do that exactly in your system. So there's a couple of ways to do it (finger's crossed). When booting at system start, use the esc key or the shift key. The first one worked for me. The timing is key. Wait until the bios banner shows then hit the esc key once. I am using Ubuntu 22.04.4 here. I have a current version of grub. The grub menu will give you options and the one you want is: root. Yes you want root privileges to set the root password. It should give you a terminal access where you can issue commands. Type: #mount -rw -o -s remount / ==> this command mounts the filesyste...

2024 So Far

I have a feeling of moving earth or walking off my itchiness. The growing fat in my belly tells me I am failing on many occasions to give in to this urge. My eyes are blurred by morning glory. I remember my father having the same ritual in the morning. After his weak stroke, he couldn't speak much, just a grunt but he would demonstrate with hand how he liked to wash his face. The weather wasn't helping. It's been raining cats and dogs the past week. The province of Rizal was soaked and spilled volumes of water into the bay and Laguna lake. Our Caimito tree was cut to no more than 4 feet from the ground. It was towering above the corrugated sheet metal of our roof. Now it lay horizontal on the yard. I calculated it could be made into a whole table and chairs set by a talented carpenter artist. I showed Lino the two big pieces of trunk that could only be moved if cut by a power saw in place. The road widening project in San Mateo was in the middle stage. One side of the road ...
