FIGURE 23-3 Advanced security options The security settings enable the SUA environment to work with some of the new Windows Server 2008 features, such as User Access Control, by enabling the superuser (SU) to impersonate the Administrator account The Enable Setuid Behavior for SUA Programs option relates to functionality that is de ned as part of the POSIX standard, which enables a process executing a le to take the User or Group ID (UID or GID) de ned on the le being executed If the UID/GID is a higher privilege than the user, the process running the program gains those high privileges This is the setuid functionality s purpose: It allows a nonprivileged user to execute a program that can run with higher privileges This has security implications if used incorrectly because, depending on the le settings, normal users could run administrator functions Thus, this option is disabled by default To set it after installation, change the Registry value EnableSetuidBinaries under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SUA key to 1 to enable setuid or 0 to disable You must restart Windows for this change to take effect

The next setting is related to case sensitivity Windows preserves the case of a le but is not case sensitive For example, you can run notepadexe, NOTEPADEXE, and nOtEpAdExE Windows does not care about the casing In a single folder, you cannot have a le of the same name, so you could not have both notepadexe and NOTEPADEXE UNIX, however, is case sensitive, so notepadexe and NOTEPADEXE are two different les that can both be stored in the same folder By selecting Change the Default Behavior to Case Sensitive, the Windows behavior can be changed to be case sensitive and match the default UNIX behavior This changes all of Windows and not just programs running in SUA (There is a security implication with this setting Suppose your system is compromised, and some malware places itself on your computer and names itself NOTEPADEXE, which now sits next to the built-in notepadexe If you run notepadexe, you might run the Trojan NOTEPADEXE instead of the correct Windows notepad executable) The casing option can be changed at any time by setting the obcaseinsensitive value under HKEY_LOCAL_MACHINE\ SYSTEM\CurrentControlSet\Control\Session Manager\kernel to 0 to enable case sensitivity, or 1 to disable case sensitivity and restore Windows to its normal mode After changing the Registry value, you must restart Windows The installation then executes When complete, new links are available in the SUA Start menu You then have a link to the C shell and the Korn shell

You can execute the shortcuts for any of the installed shells Doing so opens a command prompt that emulates the shell and gives a UNIX-like environment The Korn shell, which is a POSIX 20-compliant shell found in the /bin folder, is le ksh The C shell is found in the /bin folder, and it is le csh The C shell is an implementation of the Tenex C shell (tcsh) The Korn shell is the default shell on most UNIX environments It combines the best features from the Bourne shell and the C shell; however, there are differences between Korn and the C Shell, particularly around script execution You will likely pick a speci c shell to work from and develop under, and, in some cases, you might pick one shell to work on interactively

You can launch either the Korn or C shell from Start, SUA Alternatively, use the ksh and csh commands You have the option of adding the l switch to perform the shell s logon process

NOTE UNIX commands and using the shell are not discussed here that is beyond the scope of this chapter If you need to use SUA, you likely already know UNIX Instead, this chapter talks about some issues you might experience when running UNIX environments on Windows

One important difference is how new lines are handled between Windows and UNIX With Windows, when you press Return, two characters are added in a text le under Windows: a carriage return and a line feed (CRLF) Under UNIX, only a line feed character is used; this would cause problems if you attempted to run a script that you edited in notepadexe under a SUA shell because there would be an unexpected carriage return If you viewed a Windows text le from within SUA, you would see a Ctrl+M (^M) character at the end of each line This character is the extra carriage return Don t worry you don t need to edit every le to remove the ^M from every line SUA provides a utility (called ip) to toggle between CRLF and LF To convert a le to Windows format (CRLF), use the m switch To convert to UNIX style (LF), use the u switch For example:
