Free administrative tools software for linux

Email Administration Utility provides an IMAP-based email account management utility.
The Email Administration Utilities package can be used to manage email accounts with a series of PHP-based scripts through a browser.
Addition, Removal, and modification of accounts is possible as long as an IMAP port is available on the mail server.
The Mailadmin project was originally designed to help owners of domains that were hosted by Hub.Org Networking Services. The company wanted users to be able to create, remove or modify email accounts when ever they wanted, giving them a quicker turnaround for Mail Administration Purposes.
As the utility was developed, tested and matured into what it is today, many users requested more features or contributed reports of issues to help improve the utilities stability. Hub.Org has given me permission to release the utility as an Open Source package so that others may also benifit from the simplicity that the Mailadmin utility offers to those who need complete control over email accounts.
With this in mind, I intend to continue development by adding new features as they are requested and fix any issues that may pop up. The more users who use and test the features that the Mailadmin utility offers will help to improve the functionality offered by Mailadmin. I have opened a Sourceforge account to help manage the development and releases of the utility as it matures into what users and developers see the Mailadmin to be.
Main features:
- Administrator:
- Adding/Deleting Email accounts.
- Setting Account Quotas.
- Obtaining Administrative Access Over Older Accounts.
- Changing An Accounts Password.
- Interfaces with the Cyrus IMAP/POP3 server.
- Transaction Log system, allowing you to track changes or to help debug issues.
- Standard User:

- In Development:
- Transaction Log system, allowing you to track changes or to help debug issues.

MIME-tool is a little mime encoding tool I slapped together when I needed something on a production box at work (productions = no C development environment, only the ancient K&R compiler required for god-knows-what sys-admin task).
The resulting program will compile happilly on both the crippled C compilers bundled with some commercial *nix distributions, and on full ANSI/ISO C compilers like gcc.
I wrote this program when I needed a tool to construct MIME encoded emails with file attachments in job scripts on a production box. Being a production box it didnt have any development tools installed. However, the box DID have a K&R C compiler that appears to be necessary for some administrative task or another (configuring the kernel?). If you tried to compile even fairly simple ANSI/ISO C source the compiler bitched and moaned about all the stuff it didnt support, which will stop most folk (at least those who dont know anything about the history of the C programming language) from building their own binaries.
Since Im old enough to actually have written C code back before we had the ANSI/ISO standard and all the accompanying niceties, I was not stymied by a the lack of ANSI/ISO support. Its really not all that hard to write K&R compliant code, so long as you dont need the compiler to check your function calls for you. For a program this small, however, thats not much of a concern.
Since the program is meant to be compiled on systems with minimal support (there is no telling what unrestrained IT staff will decide must be removed in the interest of system security) I didnt bother to include a makefile. On every system I have tried, however, the program compiled with the simple incantation
cc -o mime mime.c
but your selected target system may require extra special magics.
The program supports the basic MIME standard: The caller can select the content type (application/octet-stream, text/plain, or user specified), content type encoding (7bit, 8bit, binary, base64 or auto-detected) and the boundry string (defaults to "=_MIME_CONTENT_BREAK_="). Further, the caller may specify the e-mail subject, to address, from address, carbon copy address and text for a prolog and epilog. The content type and encoding may be specified separately for each attached file.
The programs calling format is:
mime [-dDvV] [-S subject] [-F from-address] [-T to-address]
[-C carbon-copy address] [-P prolog-text] [-E epiplogue-text]
[-B boundry] {[-78abqux] [-t content-type] filename}
-d low detail debugging
-D high detail debugging
-v verbose messages
-V very verbose messages
-7 7-bit ASCII encoding
-8 8-bit ASCII encoding
-a application/octet-stream content type
-b binary encoding
-q quoted-printable encoding
-t text/plain content type
-u unknown encoding, auto-detect
-x base64 encoding
Theres really not much to this program. Once you know how the MIME messages are constructed you could do most of it manually (except for the base64 encoding, which would require a program like this), but if there are any problems with it, I would like to know about them.
Enhancements:
- A typo in the online help message was fixed.
- A known bugs section was added to the manpage.
- Proper quoting and folding were added to the filename header.

pam_krb5_migrate is a stackable authentication module that takes a username and password from an earlier module in the stack and attempts to transparently add the user to a Kerberos realm using the Kerberos 5 kadmin service.

pam_krb5_migrate PAM module can be used to ease the administrative burdens of migrating a large installed userbase from pre-existing authentication methods to a Kerberos-based setup.

The following options are recognized by the module:

debug turn debug logging on
keytab=< file > use alternate keytab for authentication (default is /etc/security/pam_krb5.keytab)
min_uid=< uid > dont add principals for uids lower than < uid >. (default is 100)
principal=< name > use the key for instead of the default pam_migrate/< hostname > key
realm=< REALM > update the database for a realm other than the default realm.

mod-auth-pipe is a module of authentication written for Apache 1 (it hasnt been tested with Apache 2, but it may work).

Actually, this module is just mod-auth-shadow with a few modifications in order to accept any program as a pipe, letting this one validate both users andr groups.

mod_auth_pipe contents the module itself and an example pipe.

mod-auth-pipe can be configured independantly for whole server, for any VirtualHost or just per Location/Directory. It has very few configuration variables and its format is very simple. In order to configure apache to authenticate, for example, access to the administrative interface of oscommerce you can type this on your httpd.conf:

< Directory /var/www/oscommerce/catalog/admin >
AuthType Basic
AuthName osCommerce admin site
AuthPipe on
AuthPipeProgram /usr/local/bin/auth-pipe
require group oscommerce-admins
< /Location >

This way, and with a well-made auth-pipe program you can be sure that only those within the group oscommerce-admins could enter that section of your web.
