strip-sunserver Some suggestions to harden the stock Solaris SPARC/x86 OS. file and modify them to give different permissions. 12. NFS exports are controlled by the /etc/dfs/dfstab file. 25. With Solaris 2.x, Sun is shipping a much more modern sendmail. and disables access to NFS through rpcbind. 41. Your FireWall-1 should not trust any other machines. to using a broadcast to find a server. file systems should be restricted to a particular hosts. 53. If you allow user to access internal services (telnet, ftp ) and FW1 connections from the encryption peer machine. 56. THE MACHINE SHOULD BE REBOOTED FOR ALL PATCHES TO TAKE AFFECT!! improving_security_sri http://www.deter.com/unix/papers/improving_security_sri.pdf Perhaps the most problematic features are those relating to networking: remote login, remote command execution, network file systems, diskless workstations, and electronic mail. All of these features have increased the utility and usability of UNIX by untold amounts. Many sites, particularly those with a large number of users, typically have several old accounts lying around whose owners have since left the organization. Ühuey/programs g+rw Ühuey/programs The Sun Yellow Pages system [Sun88b, 349-374] allows many hosts to share password files, group files, and other files via the network, while the files are stored on only a single host. Most people use this mechanism to allow trusted access between accounts they have on systems owned by different organizations who do not trust each other's hosts in hosts.equiv. unixserver Besides this UNIX Palace Server Guide, the Palace provides other online manuals; these are all available from the Palace website. NOTE -- You should be a non-root user to install the Palace server software. · You can use the ps auxww or ps -ef command (if available on your system) to display information on all currently-running processes. · You can access your site by using The Palace User software, which is available for both Windows and Macintosh platforms, or the web-based Palace Viewer. The UNIX Palace uses two different port numbers, the frontend number and the backend port number.

UnixProgrammingTools http://cslibrary.stanford.edu/107/UnixProgrammingTools.pdf commands, compiler, debugging, emacs, gdb, specify, unix shell, executing, shell, displaying, history, gcc. This article explains the overall edit-compile-link-debug programming cycle and introduces several common Unix programming tools -- gcc, make, gdb, emacs, and the Unix shell. The following discussion is about the gcc compiler, a product of the open-source GNU project (www.gnu.org). We recommend the GNU debugger gdb, since it basically stomps on dbx in every possible area and works nicely with the gcc compiler. If you want more information try xinfo if you are logged onto the console of a machine with an X display or use the info-browser mode from within emacs.

Dennis M. Ritchie Recently there has been much interest in the security aspects of operating systems and software. UNIX system and offers a number of hints on how to improve security. The first fact to face is that UNIX was not developed with security,inany realistic sense, in mind; this fact alone guarantees a vast number of holes. Each UNIX file has associated with it eleven bits of protection information together with a user identification number and a user-group identification number (UID and GID). Nine of the protection bits are used to specify independently permission to read, to write, and to execute the file to the user himself, to members of the user's group, and to all other users. b017 command, lists, environment, Unix, name1, alias, username, EZinfo, Steel, Chrome, compiler, Display. Files saved on the UITS central Unix computers Chrome, Cobalt, Zinc, Steel, EZinfo, and STARRS/SP are stored on the Network File Server (NFS). cd /n/u/username/SP/ Be sure you use the capitalization just as you see above, and substitute your own username for username. For example, if Jessica Rabbit is logged into her account on Steel, and wants to get a file on her EZinfo account, she would enter: cd /N/u/jrabbit/Ezinfo/ Now when she lists her files, she'll see her EZinfo files, even though she's actually logged into Steel.

Outlook-to-Unix-Mailbox Outlook, imap server, Linux, folders, Converting, install, Mozilla, mailboxes, Windows, format, Unix, Exchange. One way to convert uses Mozilla Mail under Windows; another involves a more complicated method. A list of conversion utilities, many commercial, may be found at: http://www.emailman.com/conversion/index.html I've had a claim that the program Kmailcvt now converts Outlook mailboxes. However, I'm not 100% sure that this claim is true, since Kmailcvt definitely converts Outlook Express mailboxes, which are completely different from Outlook mailboxes. I believe that Mozilla stores all its mailboxes as Unix mbox format files, even under Windows. If you are using Outlook in Corporate/Workgroups mode (which talks to Exchange) instead of Internet Mode (which talks to POP/IMAP servers), you'll have to change modes. At this point you can drag and drop entire folders of email from Outlook onto the IMAP server name. intro-unix http://www.nbcs.rutgers.edu/ccf/main/documentation/pdfs/intro-unix.pdf command, Unix, Computing, flags, Rutgers University Computing, University Computing Services, Campus Computing Facilities, Michelle, Scott Nieradka, account, permissions, execute. Unix is a command line operating system, unlike Windows or Mac OS. This creates a file called ".nolush" into the account, which tells Unix not to start menus when you log in. The third shows the owner of the file, while the fourth column shows the group the file belongs to. Text editors are used to create and edit text files, from personal letters, web pages, to programming code. Refer to the document entitled "Introduction to the Emacs, Pico, and Vi Text Editors" for more information about Unix text editors. It provides all information about every Unix command in an online manual. hitz http://www.usenix.org/publications/library/proceedings/usenix-nt98/full_papers/hitz/hitz.pdf UNIX, requests, ACL, filer, permissions, security, mapping, UID, UNIX-style, owner, UNIX-qtrees, NTFS-qtrees. For native file service requests (NT requests to NT-style files and NFS requests to UNIX-style files) the security model exactly matches an NT or UNIX fileserver. For non-native requests, heuristics allow a reasonable level of access without compromising the security guarantees of the native model. The NT "set ACL" operation (similar to UNIX chmod) is always denied in UNIX-qtrees. This operation converts the file from UNIX-style permissions to NT-style permissions. Section 9.1 describes how WAFL stores the ACL on disk, and section 9.2 describes the NT administrative protocols that the filer must support in order to correctly handle NT ACLs.

The Common UNIX Printing System ("CUPS") is a portable printing layer for UNIX®-based operating systems. It has been developed by Easy Software Products to promote a standard printing solution for all UNIX vendors and users. CUPS provides the System V and Berkeley command-line interfa ces. CUPS uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real-world printi ng under UNIX. CUPS is provided under the GNU General Public License and GNU Library General Public License. · PPD files list all available printer-specific options, media sizes, fonts, etc. beg8 http://www.leeds.ac.uk/iss/documentation/beg/beg8.pdf UNIX, command, exercises, characters, display, refers, format, standard input, shell, operating system, login, filestore. This document provides an introduction to the UNIX operating system. Most of the material in this document will be valid if you use any UNIX computer system, provided you use the C shell. Features of the C shell include a command history buffer, command aliases and file name completion. To identify directories in a listing give the command: % ls -F file1 progs/ test.f test Notice how the directory is identified by the slash (/) character. e.g % rm test.f The command cat is used to display the contents of a file on the screen. The command: % ls -l lists all files and directories, identifying directories by the character d at the start of each line. inter_unix command, unix, Berkeley, California, shell, MICROCOMPUTER FACILITIES DIVISION, WORKSTATION, Technology, login, server, account, Information Systems. Course Description: This is an intermediate level course on the UNIX operating system. In the Introduction to UNIX class students learn how to log in, change passwords, manipulate files and directories, and find basic information. If you would like further explanation of any of these commands, please ask the instructor or the roamer, or use the man command. If you create a .aliases (say dot aliases) file in your home directory, you can add any kind of alias to it that you want. If you modify your .login file the changes will not take effect unless you either log out and log back in or use the source command. In the case above, I used "unix" as the pattern, and "docref.txt" as the file.
