Free shell command software for linux

Shell Directory Manager is a small tool for managing often-visited directories using a shell like bash.

I offer two new commands: dm is a manager for a small database, where you name directories with a short alias. And dmcd is a function for your current shell, which lets you go to a directory given its alias in the database.

Example of use:

$ dm 1 /tmp # Adds the id 1 for /tmp
$ dm bla . # Adds the id bla for the current dir
$ dmcd 1 # Goes to /tmp
$ dmcd bla # Goes to what was your current dir
$ dm -d bla # Deletes the entry for bla.
$ dm # Shows your database
1 /tmp
$ dm -h # Shows help, and defines dmcd for sh.

Installation:

Its a script in bash - dont look for any special filename extension. Put the downloaded dm in your path.

Install the dmcd function. dm -h may give you a clue. For instance, for bash, add the following line into your .bashrc or .bash_profile (or any system wide script for each session):

function dmcd { dm -t $1 && cd `dm $1`; }

Shell over ICMP consists of two free and open source applications: one server and one client. Shell over ICMP project allows a user to connect to a remote shell daemon, by using ICMP protocol instead of classical TCP.
Entirely written in Python, soicmp is a working proof-of-concept to demonstrate that data can be transmitted across a network by hiding it in traffic that normally does not contain payloads.
How does it work?
The soicmp server is a daemon that must be started on the remote server. When the server receives a request from the client it looks into the packets payload. The payload must respect certain protocol rules. In detail the client must specify:
command
communication mode (echo|echo/reply)
authentication (y|n)
This is an example of a correct payload string sent by client to server:
$CMD ls -a $MODE echo/reply $PWD root2005 $END
If the payload matches with the server protocol specification then it will pipe the command to "/bin/sh" or "cmd.exe" and execute it. The server then reads the result from the pipe and sends it back to the client that will print it to stdout.
Moreover every client will send ICMP packets having id equal to the clients current process ID and will accept only ICMP replies having the same id value. This prevents output to be printed by other client instances running on the same workstation (this argument is also treated in the FAQs section).
Main features:
- Platform independent.
- Possibility to run soicmp daemon on multiple ethernet interfaces simultaneously handling multiple client connections.
- Possibility to specify the buffer size of outgoing packets.
- Client side source IP address spoofing.
- Remote client case-sensitive (plain texted) authentication.
- Possibility to select two communication types:
- One based on encapsulating command output in unique "one way" ICMP_ECHOREPLY (type 0) packets sent by server to client (see fig. 1).
- Another one that guarantees the correct packets delivering by using the request/response nature of ECHO and ECHOREPLY ICMP packet types (see fig.2)
- No listening sockets are listed by netstat or similar programs.

Python commandsplus is a Python module that complements the existing commands module with an extra function getstatusoutputerror, which separates the standard output from the standard error and makes it easier to evaluate return status.

Python commandsplus also includes a useful function that protects a command line argument from shell metacharacters.

AFS::Command::BOS is a OO API to the AFS bos command.

SYNOPSIS

use AFS::Command::BOS;

my $bos = AFS::Command::BOS->new();

my $bos = AFS::Command::BOS->new
(
command => $path_to_your_bos_binary,
);

my $bos = AFS::Command::BOS->new
(
localauth => 1,
);

This module implements an OO API wrapper around the AFS bos command. The supported methods depend on the version of the bos binary used, and are determined automagically.

xen-shell is a simple console application which allows you to easily allow the owner of a single Xen instance to control it, without the overhead of a web-based control panel.
Using this shell users may:
- Boot/Shutodwn their Xen guest.
- Reboot their Xen guest.
- Connect to the serial console of their runing Xen guest.
- Reimage their system to a pristine state, via xen-tools.
- Manipulate their reverse DNS information
The shell features command history, command completion, and integrated help.
It is ideal for a hosting company who wishes to over "virtual machine" hosting to their customers, and allow them to control their own instance.
