former QueSO home page <URL:http://www.apostols.org/projectz/queso/>:
How we can determine the remote OS using simple TCP packets? Well,
it's easy, they're packets that don't make any sense, so the RFCs
don't clearly state what to answer in these kind of situations.
Facing this ambiguous, each TCP/IP stack takes a different approach
to the problem, and this way, we get a different response. In some
cases (like Linux, to name one) some programming mistakes make the OS
detectable.
QueSO sends:
0 SYN * THIS IS VALID, used to verify LISTEN
1 SYN+ACK
2 FIN
3 FIN+ACK
4 SYN+FIN
5 PSH
6 SYN+XXX+YYY * XXX & YYY are unused TCP flags
All packets have a random seq_num and a 0x0 ack_num.
This is a C-language AMQP client library for use with AMQP servers
speaking protocol versions 0-8 and 0-9-1. This port only speaks the
0-9-1 protocol version, for 0-8 use net/rabbitmq-c.
raddump interprets captured RADIUS packets to print a
timestamp, packet length, RADIUS packet type, source
and destination hosts and ports, and included attribute
names and values for each packet.
This is the Cistron RADIUS daemon. Radiusd is a daemon that handles
remote authentication requests and accounting for RADIUS clients. The
clients may be terminal servers, Network Access Servers or other
RADIUS servers.
Radreport is a perl script for parsing radius logs.
While distributed by Lucent RABU, it is contributed software. Radreport has
no active maintainer and is truly open source software: if you need an extra
feature, hack it in yourself.
This is the RIPE whois client version 3 (whois3), a feature-rich
whois client with IPv6 support. This whois client is customized
for taking advantage of all the extended capabilities of the
RIPE whois db.
Ruby/DICT is an RFC 2229 compliant client-side library implementation
of the DICT protocol, written in the Ruby programming language. It
can be used to write clients that access dictionary definitions from a
set of natural language dictionary databases.
The Ruby client is a library suitable for inclusion in existing Ruby projects or
for development of standalone scripts. It provides an abstraction on top of
Datadog's raw HTTP interface for reporting events and metrics.
Fog::Radosgw is a fog backend for provisioning Ceph Radosgw - the Swift and S3
compatible REST API for Ceph. Currently, the gem only supports the S3 API, not
Swift.
Net::LDAP is an LDAP support library written in pure Ruby. It supports most
LDAP client features and a subset of server features as well.
* Standards-based (going for RFC 4511)
* Portable: 100% Ruby
