E^SEBHC to Meet at HUGCON'87
2J Saving Onr HEATH Eight-Bit Machines! > Volume 1, Number 11 *2.50 a copy, *15.00 a rear June-July, 1987 E^SEBHC To Meet At HUGCON’87 =12 Full Two 1 SEBHC JOURNAL Volume 1, Number 11, Page 2 The Details The First Annual General Meeting of the Society of Heath Eight-Bit Com- puterists will be held at the Chicago O’Hare Hyatt Regency hotel some time during Friday, 21 August, 1987. Exact time and location will be displayed from noon, Friday on the hotel lobby information terminals. The Society presently is informal—no officers or committees—and the only "official office holder" is L.E. Geisler, editor and publisher of the SEBHC JOURNAL. In the remote possibility that some SEBHC members want to establish a formal society, we advise them to send a proposed outline of same to the SEBHC JOURNAL. We will publish all those received before 5- Aug-87 in issue number 12 (August, 1987). The August JOURNAL issue will be available in the meeting room from about 13:00, Friday. Interested members can read what others have proposed in this issue, and may then discuss the proposals with other members also attending. If desired, they can draft a formal proposal for establishing a government, constitution and bylaws for the Society BEFORE meeting and acting on Lhe proposal. Note: This meeting will be quite brief, as most members are expecting to attend HUGCON-VI, and we don’t want them missing that. Subscribers visiting the meeting room may pick up their Aug-87 copy of the SEBHC JOURNAL there. -

Стр. 1 Основы операционной системы UNIX :: Учебный курс :: Live Free or Die! Стр. 1 Generated by Foxit PDF Creator © Foxit Software http://www.foxitsoftware.com For evaluation only. Основы операционной системы UNIX Copyleft (no c) - Fuck copyright! 1996-2004 В. Кравчук, OpenXS Initiative, идея, составление, перевод, примеры Введение Этот краткий (предположительно, 16 часов, из которых 6 - практические занятия) вводный курс предназначен для ознакомления с архитектурой, особенностями и основными средствами ОС UNIX. При успешном освоении, курс позволит свободно и продуктивно работать в ОС UNIX в качестве пользователя и продолжить изучение администрирования или программирования этой операционной системы. Изложение ведется, в основном, без привязки к особенностям какой-либо версии UNIX, но при необходимости конкретизации, она делается для систем SVR4, в частности, ОС Solaris 8. В последней версии (1.2, 11 марта 2004 года) обновлена хронология основных событий в истории ОС UNIX. История, версии и основные характеристики ОС UNIX История ОС UNIX началась в 1969 году в одном из подразделений AT&T Bell Laboratories, когда на "малоиспользуемой" машине DEC PDP-7 Кен Томпсон (Ken Thompson), Деннис Ричи (Dennis Ritchie) и другие (прежде занимавшиеся созданием ОС Multics) начали работу над операционной системой, названной ими первоначально Unics (UNiplexed Information and Computing System). В течение первых 10 лет развитие UNIX происходило, в основном, в Bell Labs. Соответствующие начальные версии назывались "Version n" (Vn) и предназначались для ЭВМ DEC PDP-11 (16-битовая) и VAX (32- битовая). Версии Vn разрабатывались группой Computer Research Group (CRG) в Bell Labs. Поддержкой занималась другая группа, Unix System Group (USG). Разработкой также занималась группа Programmer's WorkBench (PWB), привнесшая систему управления исходным кодом sccs, именованные каналы и ряд других идей. -
A Sane Mail System Or: Fetchmail, Procmail, Courier-IMAP-SSL, Maildir, Exim and Spamassassin
A Sane Mail System Or: fetchmail, procmail, Courier-IMAP-SSL, Maildir, exim and SpamAssassin ©2003 Stewart Smith Linux Australia Vice President http://www.linux.org.au http://www.flamingspork.com 1 Why? • Ever increasing amounts of email • Needs to be sorted or we go insane • Ever increasing amounts of SPAM • Needs to be filtered or we go insane • Needs to be efficient or we go insane! 2 Fetchmail • It’s job is to fetch mail from POP or IMAP servers • You only need to use it if you do not receive mail directly (i.e. people send mail to [email protected]) 3 What you need to know • The server you get mail from (e.g. mail.myisp.com.au) • Your username (e.g. fred) • Your password (e.g. azy68fie) • The type of server you’re connecting to (It’s probably POP3) 4 ~/.fetchmailrc • This is where you store your fetchmail configuration • Must have permissions of 0600 (u=rw,g=,o=) (think chmod 600 .fetchmailrc) • The man page is useful 5 Example .fetchmailrc set daemon 660 poll mail.myisp.com.au protocol pop3 user fred password azy68fie fetchall The ‘set daemon 660’ line tells fetchmail to check for mail every 660 seconds 6 Where does fetched mail go? • As each message is retrieved fetchmail normally delivers it via SMTP to port 25 on the machine it is running on (localhost), just as though it were being passed in over a normal TCP/IP link. The mail will then be delivered locally via your system's MDA (Mail Delivery Agent, usually sendmail(8) but your system may use a different one such as smail, mmdf, exim, or qmail). -
