Утилиты chiark

Анонс от Ian Jackson: chiark-tcl 1.0.0: cdb, adns, etc. for Tcl, plus journalling cdb

Что есть в ленни:
aptitude show libtcl-chiark-1 chiark-utils-bin chiark-scripts chiark-rwbuffer chiark-really chiark-backup

Пакет chiark-really:
Описание: really - a tool for gaining privilege (simple, realistic sudo)
really is a program that allows certain users to become whatever user they like on request. It is a bit like sudo in that respect. However, really is simpler than sudo, and doesn't give the system administrator any false security promises. So really is less of a general security risk to the system.

Unlike sudo it does not pretend that the called account can be any more secure than the calling account. so there is never a need for a password. If you wanted to restrict which commands and functions the called user can perform, use userv, not really or sudo.

Also unlike sudo, really only works if the calling user is supposed to be equivalent to root. But, really can also be used by root-equivalent users to become any user, not just root; in this way it can be a replacement for certain uses of su.


sudo делает все, чтобы компрометировать пароль пользователя, в то время как автор really об этом подумал.

Пакет chiark-scripts:
Описание: chiark system administration scripts
This package contains a number of small administration scripts used by chiark.greenend.org.uk and other systems belonging to the Sinister Greenend Organisation. Featuring:

chiark-named-conf: a tool for managing nameserver configurations and checking for suspected DNS problems. Its main functions are to check that delegations are appropriate and working, that secondary zones are slaved from the right places, and to generate a configuration for BIND, from its own input file.

sync-accounts: a simple but flexible account info synchroniser. sync-accounts is a tool for copying un*x account data from remote systems and installing it locally. It is flexible and reasonably straightforward, but lacks integration with other distributed databases such as NIS.

...

gnucap2genspic, ngspice2genspic, genspic2gnuplot: convert gnucap files and ngspice output files to genspic and genspic files to gnuplot input so they can be plotted.

hexterm: connects to serial port and allows the user interact in ASCII and hex. Ie, a hex "terminal" program which lets you speak a serial port protocol directly. (Needs tcl8.4 to be installed.)


Пакет: chiark-utils-bin:
Описание: chiark system administration utilities
This package contains a number of small administration scripts used by chiark.greenend.org.uk and other systems belonging to the Sinister Greenend Organisation. Currently featuring only:

with-lock-ex: a simple tool for acquiring a lockfile before running another program or script.
...


Пакет libtcl-chiark-1:
Описание: Tcl interfaces for adns, cdb, crypto, etc.
Tcl bindings for:
* adns (resolver library)
* cdb (constant database) plus journalling writeable database
* crypto: the nettle cryptographic library
* hbytes: bytestrings with hex as string representation but efficient


Собственно, меня сейчас интересует именно поддержка cdb, остальное - на заметку.
