Free default 0 software for linux

grub-choose-default is a simple but handy GUI to set the grub default for the next boot.

Control Grub Default through a GUI

Do you have a dual boot system? Isnt it annoying when you want to reboot from Linux into Windows or vice-versa, and you have to wait for the machine to shut down, BIOS to initialize just so that you can now select the OS that you want to boot into?

grub-choose-default gives you a GUI that you can use to easily select the next default for grub and you can go and grab a snack while your computer reboots without having to wait for anything.

Its a very simple program that just reads your grub menu entries and then lets you click on the one you want to be the next default.

How It Works

In grubs menu.lst file you need to specify default saved, so that grub consults the file default in the grub directory to see which entry it should boot. That file is then modified by grub-choose-default

Cross Platform

grub-choose-default is written in Python (which is required to be installed at the moment) and works under Linux and Windows.

Under Linux it reads /boot/grub/menu.lst and writes your choice to /boot/grub/default

Then grub-choose-default searches all your drives for a grub/menu.lst or a boot/grub/menu.lst. There currently is no way to specify manually where menu.lst resides, please let me know if this is needed.

dterm application is a simple terminal emulator, which doesnt actually emulate any particular terminal. Mainly, it is designed for use with xterm and friends, which already do a perfectly good emulation, and therefore dont need any special help; dterm simply provides a means by which keystrokes are forwarded to the serial line, and data forwarded from the serial line appears on the terminal.

Running dterm

dterm is invoked thusly:
dterm [options|device ...]

dterm attempts to read the file ~/.dtermrc for options; if this doesnt exist, it tries /etc/dtermrc. Then it parses the options passed on the command line.

The options read should include a device name, e.g "ttyS0" or "ttyd0" for the first serial port on a Linux or FreeBSD system respectively.

Once started, dterm can be got into command mode using Ctrl/]. Press enter once from command mode to get back into conversational mode. (The command character can be changed with the esc= option, e.g. esc=p to use Ctrl/P instead of Ctrl/].)

Options:

The following options can be used from command mode

300, 1200, 9600 etc: Set speed, default 9600.
5, 6, 7, 8: Set bits per character, default 8.
1, 2: Set number of stop bits, default 1.
e, o, n, m, s: Set parity to even, odd, none, mark or space, default none.
cts, nocts: Enable / disable CTS flow control, default nocts.
xon, noxon: Enable / disable XON/XOFF flow control, default noxon.
modem: Enable / disable modem control (hang up modem on exit, exit if modem hangs up), default nomodem.
bs, nobs: Enable / disable mapping of Delete to Backspace, default nobs.
del, nodel: Enable / disable mapping of Backspace to Delete, default nodel.
maplf, nomaplf: Enable / disable mapping of LF to CR, default nomaplf.
igncr, noigncr: Ignore / output carriage returns, default noigncr.
crlf, nocrlf: Enable / disable sending LF after each CR, default nocrlf.
b: Send a 500 ms break.
dtr, nodtr: Raise / lower DTR, default dtr.
rts, norts: Raise / lower RTS, default rts.
d, r: Toggle DTR / RTS.
esc= : Set command mode character to Ctrl/ (default ])
@ : Read and process configuration from .
! : Execute shell command
show: Display current configuration and modem status.
help, h, ?: Display a summary of commands.
version: Display version, copyright and warranty information.
quit, q: Exit

Examples:

Connect via ttyS1 to a system running at 2400 bps, 7 bits even parity:

dterm ttyS1 2400 7 e

Send a break in a running session:

^]
dterm> b
dterm>

tuneit is a simple command-line instrument tuner for Linux.
It uses two different algorithms for pitch detection. By default, a simple and fast Schmitt Trigger based algorithm is used to detect the fundamental frequency of an instrument.
For better and more reliable results, there is an alternative FFT based algorithm which is much more CPU intensive.
As audio capture backends ALSA and JACK are supported. By default, tuneit will try to use the hw:0,0 ALSA device.
Options:
tuneit [OPTIONS...] [captureDevice]
Valid options:
-f Use the more CPU intensive FFT based algorithm
-i List available input ports and exit
-j Use JACK as the audio transport system
-l LATENCY Measurement window size in 1/N seconds (default is 10)
-r RATE Set desired ALSA sample rate (default is 48000)
-t HERTZ Tune the A note of the scale (default is 440.0)
Enhancements:
- Now uses the floating-point version of FFTW3 and in-place transforms for better performance when using the FFT algorithm.
- Fixes to support compilation with GCC 4.0.

mod_watchcat is a module developed to provide watchcatd-awareness to the Apache 2 webserver. This allows a system administrator to set up timeouts for Apache processes, and thus provide protection against badly coded or malicious scripts. mod_watchcat can be configured to kill those resource-consuming processes before the server locks-up.

Enabling mod_watchcat

To enable mod_watchcat, you need to add the following directive to the Apache configuration file:

LoadModule watchcat_module modules/mod_watchcat.so

Configuration directives

There are four directives available for the configuration of mod_watchcat: CatType, CatTimeout, CatOrder and CatLogHandler. They are described below. The mod_watchcat directives are not context-sensitive. This means they can be included anywhere on the Apache configuration, including the .htaccess file. This, however, requires the Options item on the AllowOverride directive.

CatType type handler [ handler...]

This directive creates a new type, which will be used on the other configuration directives for the settings that will affect the specified handlers. The default type is automatically created, and doesnt accept any handlers. It is meant to be a "catch-all" for the handlers not specifically declared.

CatTimeout type timeout

This directive associates a timeout (in seconds) with the specified type. The default timeout (used for the default type) is 60 seconds.

CatOrder type [ type...]

This directive defines the matching order for the list of types specified as a parameter.

CatLogHandler

This directive is used to log the handlers of the requests. It is useful do find out the names of the handlers to be used on the CatType directive.

Configuration Examples

The configuration below defines the type script to contain the application/x-httpd-php, application/x-perl and application/x-cgi handlers. The timeout for this type is then set to 60 seconds. The default timeout (for requests that dont match the the script type is set to 1800 seconds. Finally, the matching order is set so that requests for the script type are handled before those for the default type.

CatType script application/x-httpd-php application/x-perl application/x-cgi
CatTimeout script 60
CatTimeout default 1800
CatOrder script default

The next example sets a timeout of 0 for static page handlers. This means that watchcat will not monitor those requests.

CatType static text/html text/plain
CatType static application/x-httpd-php-source
CatTimeout static 0
CatOrder static default

The example below shows how inheritance works on the configuration of mod_watchcat. The configuration specified for the /home directory inherits the global configuration but uses a different timeout value.

CatType perl application/x-perl application/x-cgi
CatTimeout perl 60
CatTimeout default 1800
CatOrder perl default

< Directory /home >
CatTimeout perl 30
< /Directory >

The next example shows a configuration that will set a timeout for PHP scripts and ignore the other handlers (note that specifying the default handler explicitly is not necessary.)

CatType php application/x-httpd-php
CatTimeout php 90
CatOrder php

This example shows how to disable the timeouts for a given directory.
CatTimeout default 3600
CatOrder default

< Directory /var/www/htdocs >
# Disable timeouts
CatTimeout default 0
< /Directory >

mod_ruid is an Apache module based on mod_suid2 only for linux.

-it runs only on linux because afaik only linux has implemented posix 1003.1e capabilities
-it has better performance than mod_suid2 because it doesn`t need to kill httpd children after one request. it makes use of kernel capabilites and after receiving a new request suids again.
-there are some security issues, for instance if attacker successfully exploits the httpd process, he can set effective capabilities and setuid to root. i recommend to use some security patch in kernel (grsec), or something..

-there are two main operation modes: stat and config
1. stat is default, httpd setuid and setgid to uid and gid of requested filename(script)/directory this is good if you use mod_vhost_alias for virtual hosting

2. config
like mod_suid2, you must define uid and gid

Installation:

1. download and install latest libcap from here
2. run /apachedir/bin/apxs -a -i -l cap -c mod_ruid.c
3. configure httpd.conf
4. restart apache

CONFIGURE OPTIONS:

RMode config|stat (default is stat)
RUidGid user|#uid group|#gid - when RMode is config, set to this uid and gid

RMinUidGid user|#uid group|#gid - when uid/gid is < than min uid/gid set to default uid/gid RDefaultUidGid user|#uid group|#gid

RGroups group1 group2 - aditional groups set via setgroups

RCoreDump - on or off, if on, you can have coredumps of httpd after crash (default off) RCoreDumpSize - limit size of coredump in bytes, 0 is unlimited (default 0)

pftabled daemon is a small helper to make OpenBSDs pf tables reachable from other hosts. One can add/delete/flush IP addresses to/from a remote table with a single UDP datagram. pftabled icludes a simple client program to do this on the command line.
Usage
pftabled [options...]
-d Run as daemon in the background
-v Log all received packets
-a address Bind to this address (default: 0.0.0.0)
-f table Force requests to use this table
-k keyfile Read authentication key from file
-p port Bind to this port (default: 56789)
-t timeout Remove IPs from table after timeout seconds
Client examples
$ pftabled-client -k /etc/key fw.example.com 56789 spam add 1.2.3.4
$ pftabled-client -k /etc/key fw.example.com 56789 spam del 4.3.2.1/24
$ pftabled-client -k /etc/key fw.example.com 56789 spam flush
Enhancements:
- A mask field was added to enable addition/deletion of whole networks.
- Client option parsing was changed.

Secure MTA is a daemon for SMTP passwords and a starter for ssmtp or msmtp.
Options:
smta [-d [-l < numer >] [-t < timer >] [-b]] | [[-e]|[-mta < mta >]] [-sock]
-d | --daemon daemon function
-l | --listen listen number [default: 2]
-t | --timer timer [default: 0=disactivated]
-b | --background background
-e | --exit close a daemon
-s | --socket unix socket [default /home/bakunin/.smta.sock]
-m | --mta msmtp|ssmtp
-h | --help this help
Usage:
smta -d -> starts as daemon, asks the password, and accepts request to unix socket.
smta -m -> connects to smta daemon, gets the password and runs the mta.
Exemple:
set to .muttrc the lines:
set sendmail="/usr/bin/smta -m ssmtp -au bakunin"
---- ~/bin/posta ----
#!/bin/bash
# download new emails:
fetchmail -a
# Set the smtp password:
smta -d -b -t 3600
# Mutt
mutt
# Close the smta
smta -e
mutt runs smta, and smta runs ssmtp -au bakunin -ap password
Enhancements:
- Man page updates and a bugfix for the Unix socket path.
