This Perl module reads and parses Apache configuration file, expanding constructs like Include, IncludeOptional, IfModule, IfDefine, Use, etc.

This Perl module provides a mechanism for detecting version, default settings, and the preloaded modules of the Apache httpd server. It does so by locating the server binary, invoking it with appropriate options and analyzing the output it produces.

This perl module aims to provide a generalized implementation of parse tree for various configuration files. It does not implement parser for any existing configuration file format. Instead, it provides an API that can be used by parser implementors to build internal representation for the particular configuration file format.

A perl module supplying a parser that converts the HAProxy configuration file to a parse tree and provides methods for various operations on this tree, such as: searching, modifying and saving it to a file.

Config::Parser provides a framework for writing configuration file parsers.

A Perl module for parsing the ldap.conf configuration file.

Perl extension for creating backup file copies. Three backup naming schemes are supported: simple backup creates backup file name by appending single tilde character to the original file name, numbered backup creates backup name by suffixing the original file name with .~N~, where N is a decimal number. Finally, automatic backup selects numbered scheme if at least one numbered backup file already exists and falls back to the simple backup otherwise.

A simple web gallery driver, written in Guile.

Lua library for handling big amounts of redirect rules in HAProxy.

Hostproc provides detailed information about processes running on a host over SNMP. The information is grouped in a way similar to the ps(1) output. Additional aggregating features allow the administrator to provide summary statistics for processes matching some criteria and to exclude such processes from the detailed output. The latter feature can be used, in particular, to separate statistics for processes running on the host from those that are run within docker containers. The program is built as a sub-agent for Net-SNMP snmpd and is Linux-specific.

Using a sophisticated configuration file, Rush gives you complete control over the command lines users can execute, system resources they can use, etc. In particular, it allows to run remote programs in a chrooted environment.

A Docker authorization plugin that controls container creation. It enables the administrator to excercise control over the containers that users are allowed to create and decide whether to permit creation of privileged containers, what parts of the host file system can be visible to containers via bind or volume mechanism, what memory limits to apply, etc.

A builder for Slackware packages.

Formats a slack-desc file for Slackware package.

Upgrades the Slackware installation to a new release. Two upgrade types are supported. In normal upgrade only packages already installed on the system are upgraded. In full upgrade, all packages from the new release are installed. A combination of the two can be achieved by supplying a list of additional Slackware series when running the normal upgrade.

A simple load balancer. The utility monitors a set of remote servers, obtaining a set of numeric values via SNMP. These values are used to compute a single floating-point number, called a relative load for that server. The servers are then sorted in order of increasing loads and the resulting table is output (using a configurable format string) to a file or pipe.

A replacement for /bin/login, intended to be used in system start-up script wherever the root maintenance is needed. It does not update utmp/wtmp and hence is safe to be called when the partition containig these files is not mounted.

An extendable socket map server with a set of modules and framework for writing new socket maps and testing them.

Decomissioned.

Displays the amount of swap space used by each running program. The utility is Linux-specific.

This program provides system log forwarding facility for confined environments, such as docker containers. It listens for incoming system log messages on the UNIX socket file /dev/log and forwards them to the specified remote server. Relayed messages are normalized to make sure they comply with the RFC 3164. In particular, hostname is added if necessary. This is important in docker environments, since otherwise the collector would insert the IP address of the container or gateway in place of the missing hostname, and neither IP is informative enough to identify the container where the message originated.

Decomissioned.

Monitors state of running docker containers via SNMP. The package provides two utilities:

• tallyman

  A health state collector to be run inside the container.

• stevedore

  A container state collector and SNMP agent daemon.

Each container is supposed to run the tallyman command as part of its HEALTHCHECK configuration. This tool takes as its argument the command line that does the actual checking, collects its return and sends it over to the stevedore daemon that acts as a collector and simultaneously as a SNMP subagent, delivering the collected information to the snmpd daemon.

Notifies the Translation Project about new POT files

Dynamically loadable object module for net-snmp snmpd that provides access to Varnish Cache statistics.

Emacs major mode for editing VCL files.

This Varnish Cache module implements basic HTTP authentication against password files created with the Apache htpasswd utility.

This module provides API for writing binary log files from Varnish VCL scripts and the utilities for listing and searching in such files.

A Varnish Cache module implementing database-driven rewrite rules. Intended for use with web sites that need an exceedingly big number of redirect and/or rewrite rules, Vmod-dbrw allows the administrator to keep all rules in an SQL database of arbitrary structure, thereby considerably speeding up their handling. Another advantage of this approach is that rewrite rules stored in a database are easier to maintain.

This module for Varnish Cache adds to it the ability to look up values in a textual dictionary. A dictionary is a disk file containing on each line a keyword-value pair, separated by arbitrary amount of whitespace. Leading and trailing whitespace is ignored. Empty lines and comments (beginning with ‘#’ as the first non-whitespace character) are allowed. Two functions are provided: dict.load loads the dictionary from a disk file into hash table, and dict.lookup retrieves value for a given key.

A module for Varnish Cache that provides API for using geolocation functions in VCL scripts.

This module is for Varnish Cache what mod_remoteip is for Apache. It determines the actual client IP address for the connection, using the useragent IP address list presented by a proxy or load balancer via the request headers and a preconfigred list of trusted IP addresses.

This module provides SQL interface for Varnish Cache. Both MySQL and PostgreSQL are supported.

This module implements token bucket filtering for Varnish Cache.

Extended variable support for VCL

A wiki translator, a package that supplies Python classes for translating Wiki Markup into another kind of markup, such as, e.g. plain text and HTML. It has been superseded by wikitrans.

This package provides a set of C functions for parsing input strings. Default parsing rules are are similar to those used in Bourne shell. This includes tilde expansion, variable expansion, quote removal, word splitting, command substitution, and path expansion. Parsing is controlled by a number of settings which allow the caller to alter processing at each of these phases or even to disable any of them. Thus, wordsplit can be used for parsing inputs in different formats, from simple character-delimited entries, as in /etc/passwd, and up to complex shell statements.

An automatic release submission daemon. It implements the GNU automatic upload procedure, and supports upload directive files of version 1.2.

Wyslij-po runs basic checking on PO files given in the command line and submits them to the Translation Project robot.

Xenv is a text preprocessor. It reads input from files (or the standard input, if none are supplied) and prints it on the standard output, replacing references to environment variables with their actual values. Variables are referenced using POSIX-compatible shell syntax: $NAME, ${NAME}, ${NAME:-word}, ${NAME+=word}, ${NAME:=word}, ${NAME:?word}. A special ternary construct is provided: ${NAME:|word1|word2}, which substitutes the expansion of word1 if NAME is set and the expansion of word2 otherwise. Preprocessor directives provide support for inclusion of external files, conditional text expansion (depending on the value of an environment variable or exit code of an external command), diversions, for and foreach loops etc.

A set of Guile primitives for parsing and processing XML files.
