Udgivelsen af den specialiserede kommandolinje-shell GNU Rush 2.2 (Restricted User Shell) er offentliggjort. Den er designet til brug i systemer med begr\u00e6nset fjernadgang, hvor det er n\u00f8dvendigt at begr\u00e6nse brugerens handlinger. Rush g\u00f8r det muligt at definere, hvilke kommandolinjefunktioner brugeren kan benytte, og hvilke ressourcer der stilles til r\u00e5dighed (hukommelsesst\u00f8rrelse, CPU-tid osv.). For eksempel kan Rush bruges til fjernk\u00f8rsel af programmer i et chroot-milj\u00f8, hvilket \u00f8ger sikkerheden ved at give adgang gennem programmer som sftp-server eller scp, som som standard har adgang til hele filsystemet. <\/p>\n
I det nye udgave er der mulighed for at bruge tilstandscheck for filer og mapper i filsystemet (for eksempel kan man nu i reglerne tjekke filtyper, adgangsrettigheder og ejere af filer). Formatet for mulighederne til kontrol minder om arbejdet med kommandoen 'test'. For eksempel, for at tjekke om en sti eksisterer og henviser til en mappe, kan man bruge konstruktionen 'match -d \/var\/lock\/sd'. <\/p>\n
Derudover er version 1.7 af v\u00e6rkt\u00f8jet GNU pies blevet offentliggjort, som har til form\u00e5l at koordinere opstarten og udf\u00f8relsen af applikationer. Baseret p\u00e5 den angivne konfiguration starter programmet eksekverbare filer i baggrunden, overv\u00e5ger deres k\u00f8rsel og tillader binding af h\u00e5ndteringsprogrammer til forskellige tilstande. For eksempel kan det genstarte programmet i tilf\u00e6lde af en nedbrud, k\u00f8re et andet program eller sende en meddelelse til administratoren. Desuden kan GNU pies fungere som init-proces, der startes f\u00f8rst under systemopstart, og underst\u00f8tter formatet \/etc\/inittab. <\/p>\n
I den nye version af GNU Pies er metoden til h\u00e5ndtering af konfigurationsfiler \u00e6ndret. Den indbyggede forbehandler er fjernet, og hver fil, der er angivet i udtryk '#include' og '#include_once', behandles nu separat ved hj\u00e6lp af en ekstern forbehandler (tidligere blev alle substitutter '#include' f\u00f8rst udvidet af den indbyggede forbehandler, og derefter blev resultatet behandlet af den eksterne forbehandler m4 som en helhed). Der er tilf\u00f8jet nye diagnostiske udtryk '#warning 'TEXT'', '#error 'TEXT'' og '#abend 'TEXT'' for at generere advarsler og vise fejl. <\/p>\n
Det er ogs\u00e5 v\u00e6rd at bem\u00e6rke udgivelsen af GNU mailutils 3.14, som tilbyder biblioteker og v\u00e6rkt\u00f8jer til at udf\u00f8re forskellige opgaver relateret til e-mail, s\u00e5som at analysere felter i beskeder, arbejde med postdatabaser (mailbox, maildrop, maildir), filtrering af beskeder, udtr\u00e6kning af e-mailadresser og URL'er, behandling af MIME-blokke, samt at hente e-mails fra eksterne servere<\/a> ved hj\u00e6lp af protokollerne IMAP4 og POP3 og sende e-mails via SMTP-protokollen, herunder brugen af TLS, SASL og GSSAPI. <\/p>\n I den nye version af GNU mailutils er underst\u00f8ttelsen af TLS blevet fuldst\u00e6ndig omskrevet. Der er tilf\u00f8jet en indstilling tls.handshake-timeout for at angive en timeout for TLS. Funktionen mu_mailbox_append_message_ext er blevet tilf\u00f8jet til at tilf\u00f8je en besked til mailbox. I mail-nyttigheden er der tilf\u00f8jet kommandoen unread (U) for at fjerne l\u00e6sem\u00e6rket fra en besked, og i kopieringskommandoer til en anden mailbox er bevarelsen af status (l\u00e6st eller ul\u00e6st) sikret. Koden for parserne og scannerne er blevet omskrevet, og nu kr\u00e6ver ops\u00e6tningen GNU bison og flex. Der er tilf\u00f8jet mulighed for at inkludere mime-typer i biblioteket libmailutils. I Maildir og MH er refleksionen af afsenderoplysninger, der sendes i kommandoen 'MAIL FROM' under SMTP-sessionen, stoppet i overskrifterne X-Envelope-Sender og X-Envelope-Date, i stedet gemmes disse data i overskrifterne Return-Path og Received. \u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 \u0441\u043f\u0435\u0446\u0438\u0430\u043b\u0438\u0437\u0438\u0440\u043e\u0432\u0430\u043d\u043d\u043e\u0439 \u043a\u043e\u043c\u0430\u043d\u0434\u043d\u043e\u0439 \u043e\u0431\u043e\u043b\u043e\u0447\u043a\u0438 GNU Rush 2.2 (Restricted User Shell), \u0440\u0430\u0441\u0441\u0447\u0438\u0442\u0430\u043d\u043d\u043e\u0439 \u043d\u0430 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u0435 \u0432 \u0441\u0438\u0441\u0442\u0435\u043c\u0430\u0445 \u0441 \u0443\u0440\u0435\u0437\u0430\u043d\u043d\u044b\u043c \u0443\u0434\u0430\u043b\u0451\u043d\u043d\u044b\u043c \u0434\u043e\u0441\u0442\u0443\u043f\u043e\u043c, \u0432 \u043a\u043e\u0442\u043e\u0440\u044b\u0445 \u0442\u0440\u0435\u0431\u0443\u0435\u0442\u0441\u044f \u043e\u0433\u0440\u0430\u043d\u0438\u0447\u0435\u043d\u0438\u0435 \u0434\u0435\u0439\u0441\u0442\u0432\u0438\u0439 \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u044f.
