Free tells software for linux

Sishell provides a reverse shellcode kit for x86 Linux, FreeBSD, NetBSD, and OpenBSD.

sishell is a reverse (connecting) shellcode kit for x86 Linux, FreeBSD, NetBSD, and OpenBSD. You may generate both regular shellcode (no NULLs) and stand-alone ELF executables (e.g. for injection into Web script vulnerabilities).

It is distributed with a Makefile system, a custom ELF brander (brandelf), and a C example code generator.

Shellcode is a piece of machine-readable code, or script code that has just one mission; to open up a command interpreter (shell) on the target system so that an "attacker" can type in commands in the same fashion as a regular authorized user, or system administrator of that system can (with a few
not-so-important exceptions though). However, in order to get remote access to the shell, youre going to need some kind of networking support in your
shellcode too.

If the shellcode is to be used to exploit buffer overflows (e.g.) in binary, machine-readable software, the shellcode is going to have to be machine-readable (binary) and, to make things more complicated, it cant contain any null bytes (0x00). Null (0) is a string delimiter that tells all C string functions (and other implementations) that once found the function should stop processing the string (thus, a null-terminated string). We dont want an input function to stop processing our shellcode, since we want to upload the entire shellcode into the vulnerable program and tell it to execute it.

Hearts is a little card game for four persons.
A computer version of the game comes with Microsoft Windows and is a pretty popular little thing. When I switched to using Linux, I really wanted to play it, but I didnt find anything at all, so I decided to write it myself and here it is.
Enhancements:
Fixed all known bugs:
- The card passing was always to the right.
- Portability issue regarding setting the random seed (std::random_shuffle + std::srand issue).
- A lot of processes were left running.
- Only one match (ie, a series of games until a player gets 100 points) was possible.
- Status bar tells the user what he he should do at every step (play, give cards right, etc.)

Progress is a utility used in a pipe to report progress of data transfer to standard error. Command-line arguments tells to specify how frequently to report, what character to use to report, and how much buffering to do.
Enhancements:
- February 9, 2003
- progress 1.0
- Initial announcement

Divide rectangles is a program which helps you divide a rectangular sheet of paper into small pieces.

You give the size of the sheet and the size of the pieces, it tells you how to cut and how many pieces you will have.

I often use my computer to play music when I am having visitors or when I am just not in front of the monitor. I wanted some way to still be able to see what song was playing. As my TV is connected to the computer I decided to make a screen saver that would do just this. (you dont need to even own a TV to use this script, but my TV is in my living room and my computer is not...)

KoverSS script creates an image based on the currently playing song in Amarok, then changes your screen saver to KSlideshow and tells it to display this particular image. It then restores your original screen saver settings.

The script has some basic settings configurable via kdialogs:

Party / safe - mode:

The script can be configured to lock the screen saver, you will need your password to return to the desktop. This is great if you are having a party and dont want everybody to use the computer for surfing or changing track every other minute.

DPMS:

I use display power management to turn off my monitor after a given period of time. This did not work well with my idea. Therefore I created an option to turn off DPMS, and turning it back on when the script is exited or Amarok is shut down.

RankQuest SEO Tools aims to help Web masters in search engine optimization. RankQuest SEO Tools is Keyword Finder and Meta Tag Analyzer are among the most important tools for SEO. Keyword Finder lists the keywords in the meta keyword tag of a site.

Meta Tag Analyzer examines the meta information of a site and tells you if the content is search engine friendly or not. Many search engines uses the details in the meta tag for ranking purpose, so this tag must be effectively analyzed for improvement in ranking.

pam_sqlite allows developers to authenticate users against a table in an SQLite database. pam_sqlite supports checking account information (pam_acct_expired, new_authtok_reqd) and updating authentication tokens.

Compilation & Installation

pam_sqlite is autoconfed, thus, compiling should be a matter of:

$ ./configure
$ make
$ make install

Compilation has been tested on RedHat Linux 7.3.

You will need to have SQLite library and header files for this module to compile.

See test.c for an example application that authenticates using this module.

Configuration:

For the service you wish the module to be used, you need to edit the /etc/pam.d/ file or /etc/pam.conf, and add the relevant lines.

For example:

auth required pam_sqlite.so
account required pam_sqlite.so
password required pam_sqlite.so

Configure the database, and table the module should use with the configuration file /etc/pam_sqlite.conf. An example of this file:

database = /etc/sysdb
table = account
user_column = user_name
pwd_column = user_password
expired_column = acc_expired
newtok_column = acc_new_pwreq
debug

expired_column tells PAM if the user account has expired. Set it to 1 or y if it has.
newtok_column tells PAM if the user needs a new password. Set it to 1 or y if it does.

Note that for backwards compatibility with earlier versions, options specified in the configuration file can be supplied as module arguments as well. Module arguments will override the configuration file.

Configuration Options:

database - the database which should be connected to
user_column - the column containing usernames
pwd_column - the column containing the passwords
expired_column - this column should contain 1 or y if the account
has expired
newtok_column - this column should contain 1 or y if the user
needs to change their password
debug - this is a standard module option that will enable
debug output to syslog (takes no values)
pw_type - specifies the password encryption scheme, can be one
of clear, md5, or crypt. defaults to clear.
config_file - specifies the path to a file to read for further
configuration options
sql_verify - specifies SQL template to use when verifying the
the password for a user
sql_check_expired - SQL template to use when checking for account expiry.
sql_check_newtok - SQL template to use when checking to see if the user
needs to change their password.
sql_set_passwd - SQL template to use when updating the password for
and user.
