Many users of Windows XP and Vista will want to try Linux at some point, often just to see what all the fuss is about. There are many different Linux distributions and it isn’t convenient for a non-technical user to set up dual booting alongside an existing Windows install. Thankfully, there are tools available which mean you can play with a full Linux install inside the familiar surroundings of Microsoft Windows.
Hibernate takes a snapshot of everything you got on RAM (including any windows and apps running) and saves it to a special hard disk file and then shuts the computer down, when you resume from hibernation the computer boots a bit faster than a normal power up bootup. This method does not consume any power while the computer is off.

Result:
IPHost (chicagotech.net)
IPHost = chicagotech.net
Port = 80

Log files for Unix vary from flavor to flavor, but there are a few guidelines as to where these logs are kept.
System log files and accounting files are in /var/adm, /var/log, or sometimes /usr/adm. Common log files include 'messages', 'syslog', and on some systems 'sulog'. Checking '/etc/defaults' and '/etc/syslog.conf' may reveal more. Also 'wtmp', 'utmp', and 'lastlog' will contain information regarding logins.
All Unix systems have an account called root. This account is also commonly known as the superuser. Actually, any account with a user ID (UID) and group ID (GID) of zero could be considered a superuser account. It is possible that a system administrator will rename the root account for obfuscation, but this is rather impractical as many applications not only require that there be an
/etc/passwd file stores essential information, which is required during login i.e. user account information.
/etc/passwd is a text file, that contains a list of the system's accounts, giving for each account some useful information like user ID, group ID, home directory, shell, etc. It should have general read permission as many utilities, like ls use it to map user IDs to user names, but write access only for the superuser (root)
/etc/shadow file stores actual password in encrypted format for user's account with additional properties related to user password i.e. it stores secure user account information. All fields are separated by a colon (:) symbol. It contains one entry per line for each user listed in /etc/passwd file Generally, shadow file entry looks as follows
People always ask me with this kind of question, commonly they were looking up for a distro that close enough to Windows OS appearance. It’s important to see the hardware factor, Since every Linux distribution contains the basic packages and can be built to meet almost any requirement (because they all use the Linux kernel).
