Free dns domain expiration check software for linux

Sendmail Confirmation System is an Sendmail milter plugin that is designed to reduce the amount of junk email received. SMC uses a dynamic local and DNS based remote "whitelists" (for known/trusted senders), DNS based "blacklists" (for undesired senders), and an original "autoauthentication" system (for unknown, but legitimate senders). In additional SMC has a set of useful features which allows to preserve mail recipients from dangerous message attachments, HTML includes. SMC is an Sendmail tm milter (plugin), which stops the junk mail messages without receiving one.
SMC uses 3 original algorithms, one of which is "Check relay by NS" simulates a dynamical whitelist and will always accept the messages from mail systems satisfying to following conditions:
1) Mail domain name (the host part of the senders e-mail address) must have an MX records;
2) Mail domain name and the connection host address must be resolved;
3) Connection host must be listed at the one of nameservers which hold the senders mail domain name.
The second from the developed algorithms is a "check delays" algorithm which is based on statistical check of delivery delays, generated by a [tempfail] return code, that allows to exclude a direct receiving of a mail, which not passed through the standard mail server.
NOTE: Using this feature the delivery of the mail from unknown, but legitimate senders will be delayed for a count of 5-minutes checks, which setted by the "maxcount" configuration parameter.
And the third of original algorithms is "autoconfirmation" algorithm: The sender of a "mail contact" (sender-recipient pair) means as authenticated (whitelisted) if the filters statistics module has registered the both of a sended forward (request) and a recieved backward (reply) messages of this contact. The messages from the such authenticated senders will never be delayed by the previos "check delay" algorithm.
Enhancements:
- Add checks to prevent overwrite all configuration data during install.
- Minor bug fix in ns-relay code.

Domain Auditor project was written to audit and track accounts within a domain. This tool uses LDAP queries to a definable Active Directory server to find various definable classes of accounts.
Initially it will operate interactively, but capabilities may be added in the future to automate functions (i.e. generate reports on a scheduled basis). The installation script handles most installation chores, so setup is very straightforward.
The tool is beta status at this time, but is in being used to generate SOX reports for my employer.
Main features:
- Reports - This function will display a list of defined reports, when invoked it will generate a list of accounts from AD (via LDAP queries) the results returned will depend on what you have defined for the filter for any particular report class under Sysadmin
- Sys Admin - This function will allow you to changes the system settings for LDAP server and port, base DN, Bind DN, username and password, and the database settings (mySQL only at this time). You may also add the report class definitions and their matching LDAP filters within this module
- User Admin - This screen is used to define users for the system and their rights. Usernames are used as the primary value, and entered values are validated via LDAP queries
- Audit Logs - The system logs all changes to the information stored and this page will allow you to review the data from these logs

Bandwidth Check is a small utility that helps an administrator measure the available bandwidth. In order to make use of this utility, you will need to turn on the chargen service, which is provided in many inetd implementations.

In order to make use of this utility, you will need to turn on chargen protocol.

To enable chargen on Linux:

create the following file /etc/xinetd.d/charge
service chargen
{
type = INTERNAL
id = chargen-stream
socket_type = stream
protocol = tcp
user = root
wait = no
disable = no
}
service xinetd restart

To Compile bwcheck

gcc -o bwcheck bwcheck.c

To execute

ssl-cert-check is a Bourne shell script that checks the expiration status of digital certificates on SSL servers.
It supports both interactive and batch modes and easily integrates with cron. It provides custom expiration thresholds and can be configured to send email if a certificate is close to expiring.
Enhancements:
- This release contains a new "-i" option to print the certificate issuer.
- The requirement to use GNU date has been removed (the program now uses a built-in Julian date routine).
- The documentation has also been significantly updated to include numerous useful examples.

IPv4/IPv6 DNS and DHCP config generator is a tool that can be used to generate DNS and DHCP configuration files from a central configuration file.
IPv4/IPv6 DNS and DHCP config generator supports IPv4 and IPv6 addresses and reverse zones and multiple IPv4 networks, and generates one reverse DNS zone for each /24 network.
Main features:
- Multiple Subnets resp. DHCP configuration files are supported
- Multiple IPv4 networks are supported. addrconf will generate one reverse DNS-Zone for each /24 network.
- One IPv6 reverse DNS-zone is supported. Preferably with a /48 prefix.
- addrconf does not create complete config files. For the DHCP config files it created only the "host asdf {... }" stancas and for the DNS zonefiles it generates only the A, AAAA, and PTR records. These generated files can be included in the DNS and DHCP config files.
Enhancements:
- The need to change the Perl script for configuration changes was removed.
- General configuration options can now be specified inside the (hosts) configuration file.
- Multiple configuration files are now supported.
