Out of curiosity, are you asking for a specific research/project that you need
some data for?
GTSM is not a replacement for the ACL filtering the bgp speakers or the MD5 (
that is widely supported).
If GTSM is not supported you can always predefine the TTL it in the session
and manipulate

I still use a tool I
Cragslist is blocking our largest IP block, if someone from CL could
contact me off list, that would be great.
As a small operator, we mainly use Icinga for the reasons Chuck mentioned.
The API allows us to do updates based on configuration parameters we've
created in a custom MySQL database.

the rst attacks were a very serious problem. attacks were very real and
very disruptive. gtsm et alia were a few years later.

I run OpenNMS currently, and the one problem I have is it's very peculiar --
one might say academic -- terminology and structure. It's not a point-and-click
interface, despite being web-based. Instead, you must wrangle with pollers and
responders and notifiers. Eventually I got my head around
Take a look at opennms.org
Scales very well. Lots of API hooks for integration with other data
sources and applications.
It is open source and they offer paid support services, one-time (e.g.
setup and training) or on-going support contracts.

Here’s a snapshot of what tends to work for me, along with my $0.02 of thoughts:
- Observium handles polling, graphing and alerting for SNMP exposed objects on
network devices,
- I feel that a visual representation of the physical network

We are looking for a new network monitoring system. Since there are so many
operators on this list, I would like to know which NMS do you use and why?
Is there one that you really like, and others that you hate?
For free options (opensouce), LibreNMS and NetXMS come highly recommended
by many
Well, think about RST attacks, in which someone bombards a TCP connection with
TCP RESET in the hopes of threading a needle and taking it down. It's not the
end of the world - BGP restarts - but there is an outage. The simplest way to
protect against that (and against having someone with a
Just to point out -
Data about md5 attacks from various organizations will depend on a number of
factors such as -
Is BGP TTL Security check being done?
Are anti-spoofing ACLs enabled?
uRPF enabled? Strict or Loose?
BGP Session over a separate interface (tunnel)?
