Serbert is a command line utility which performs a Bit Error Rate Test (BERT) on serial lines for Unix and its variants. It does this by transmitting bytes, and waiting for their uncorrupted return.

Serbert, however, does not provide a true Bit Error Rate Test (BERT), as it does not check the individual bits returned. It uses the operating systems standard serial interface, which provides the status of each returned byte.

WMtemp is based on code from (WMMemLoad and the sensor code is inspired by WMgtemp).
It displays the CPU temperature and the system temperature in a dockapp, these temperatures are obtained through lm_sensors.
The layout is in line with WMMemLoad and WMCPULoad (and a couple of others).
Enhancements:
- Found out Debian (http://www.debian.org/) has a package and the maintainer has added a manual page, which Ive shamelessly copied. Only the part explaining this package had no manual page is removed, since its no longer true. Thanks to Lars Steinke < lss@debian.org > for maintaining the Debian package.

JBooleanExpression is a simple Java API to evaluate a Boolean String Expression like "!true&&false||true" (parse a Boolean String Expression to a boolean primitive type).
Enhancements:
- Bugs were fixed.
- A demo class was added.

PAM has traditionally assumed that services doing authentication have the ability to interact with the user. Unfortunately, this isnt true for services that implement non-interactive and/or fixed protocols, such as FTP and POP3.

This is typically worked around by making the flawed assumption that PAM_PROMPT_ECHO_ON requests the username and PAM_PROMPT_ECHO_OFF requests the password.

With pam_userpass, this assumption is no longer required. pam_userpass uses PAM binary prompts to ask the application for the username and password specifically.

pam_userpass doesnt perform any actual authentication. An actual authentication module should be stacked after pam_userpass and told to use the authentication token (password) provided by pam_userpass.

Sysfence project is a resource monitoring tool designed for Linux machines. While running as daemon it checks resource levels and makes desired action if some values exceed safety limits.
Main features:
- notifying system administrators when something goes wrong,
- stopping services when system performance is dropping too low and starting them when its going up again,
- periodically restarting memory-leaking processes,
- dumping system statistics in critical situations
Usage
Sysfence reads its configuration from file(s) specified in argument list. Config files may contain one or more rules describing conditions and actions to be performed.
Rule has syntax like this:
if {
resource1 > limit1
or
{ resource2 < limit2 and resource3 < limit3 }
}
run once command-to-be-run
The block enclosed within {} brackets describes condition. When its result is TRUE, following command is invoked.
The once keyword is optional. If present, the command is executed only once after condition becomes TRUE. Next execution will take place only if condition becomes FALSE and then TRUE again. Without once keyword, command is invoked periodically, after every resource check that gives TRUE, no matter what was the condition result before.
Command specified right after run keyword is passed to /bin/sh, so it may contain more than one instruction or even whole script. But be careful - rule checking is suspended unless command execution has been completed! (Other rules are unaffected.)
As resources, following ones can be given:
- la1 - load average during last minute.
- la5 - load average during last 5 minutes.
- la15 - load average during last 15 minutes.
- memfree - lower limit for free memory amount.
- memused - upper limit for memory used by processes.
- swapfree - lower limit for free swap space.
- swapused - upper limit for swap space in use.
Enhancements:
- This release contains bugfix for wrong memory levels recognition on non-vanilla kernels.

Unix::Conf::Bind8::DB::A is a Class representing A records.

METHODS

Methods specified here are overridden. They might or not be differnt from the derived ones. For other methods refer to the METHODS section for Unix::Conf::Bind8::DB::Record.

new ()

Arguments
LABEL => string,
CLASS => string, # IN|HS|CHAOS
TTL => string|number,
AUTH_NS => nameserver,
MAIL_ADDR => rp,
SERIAL => zone_serial_no # number
REFRESH => refresh,
RETRY => retry,
EXPIRE => expire,
MIN_TTL => min_ttl,
PARENT => reference, # to the DB object datastructure

Class constructor. Creates a new Unix::Conf::Bind8::DB::* object and returns it if successful, an Err object otherwise. Do not use this constructor directly. Use the Unix::Conf::Bind8::DB::new_* equivalent instead.

auth_ns ()

Arguments
auth_ns
Object method. Get/set the records auth_ns. If an argument is passed, the invocants auth_ns is set and true returned, on success, an Err object otherwise. If no argument is passed the invocants auth_ns is returned.

mail_addr ()

Arguments
mail_addr
Object method. Get/set the records mail_addr. If an argument is passed, the invocants mail_addr is set and true returned, on success, an Err object otherwise. If no argument is passed the invocants mail_addr is returned.

serial ()

Arguments
serial
Object method. Get/set the records serial. If an argument is passed, the invocants serial is set and true returned, on success, an Err object otherwise. If no argument is passed the invocants serial is returned.

refresh ()

Arguments
refresh
Object method. Get/set the records refresh. If an argument is passed, the invocants refresh is set and true returned, on success, an Err object otherwise. If no argument is passed the invocants refresh is returned.

retry ()

Arguments
retry
Object method. Get/set the records retry. If an argument is passed, the invocants retry is set and true returned, on success, an Err object otherwise. If no argument is passed the invocants retry is returned.

expire ()

Arguments
expire
Object method. Get/set the records expire. If an argument is passed, the invocants expire is set and true returned, on success, an Err object otherwise. If no argument is passed the invocants expire is returned.

min_ttl ()

Arguments
min_ttl
Object method. Get/set the records min_ttl. If an argument is passed, the invocants min_ttl is set and true returned, on success, an Err object otherwise. If no argument is passed the invocants min_ttl is returned.
