do know what a rootkit is?
Hi,
Rootkit scanner is scanning tool to ensure you for about 99.9%* you're clean of nasty tools. This tool scans for rootkits, backdoors and local exploits.
A root kit is a set of tools used by an intruder after cracking a computer system. These tools can help the attacker maintain his or her access to the system and use it for malicious purposes. Root kits exist for a variety of operating systems such as Linux, Solaris, and versions of Microsoft Windows.
A hacker security tool that captures passwords and message traffic to and from a computer. A collection of tools that allows a hacker to provide a backdoor into a system, collect information on other systems on the network, mask the fact that the system is compromised, and much more. Rootkit is a classic example of Trojan Horse software. Rootkit is available for a wide range of operating systems.
Download rootkit
wget http://downloads.rootkit.nl/rkhunter-1.2.8.tar.gz
tar xvzf rkhunter-1.2.8.tar.gz
cd rkhunter
./installer.sh
Installation done!
Now lets start the scan
rkhunter -c

I have created a small FAQ for the "Unix for Dummies" forum.
Hopefully this will be useful, as there are questions which are asked (and answered) repeatedly.

swapmem_on
swapmem_on(5) OBSOLETE swapmem_on(5) NAME
swapmem_on - OBSOLETE kernel tunable parameter DESCRIPTION
The tunable is obsolete. Processes will always be allowed to use pseudo-swap space if it is available. In previous versions of HP-UX, system configuration required sufficient physical swap space for the maximum possible number of processes on the system. This is because HP-UX reserves swap space for a process when it is created, to ensure that a running process never needs to be killed due to insufficient swap. This was difficult, however, for systems needing gigabytes of swap space with gigabytes of physical memory, and those with workloads where the entire load would always be in core. This tunable was created to allow system swap space to be less than core memory. To accomplish this, a portion of physical memory is set aside as "pseudo-swap" space. While actual swap space is still available, processes still reserve all the swap they will need at fork or execute time from the physical device or file system swap. Once this swap is completely used, new processes do not reserve swap, and each page which would have been swapped to the physical device or file system is instead locked in memory and counted as part of the pseudo-swap space. WARNINGS
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation, some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun- able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was factory installed on your system, see at AUTHOR
