Re: [FW-1] fw sam error



Hello Manuel,

I appreciate your assistance.

I upgraded to HF-1 on both the management and on the enforcement modules. I
have reset SIC and I have set, set and reset the putkey process (even
messing it up to see the error/failure messages) and tried the syntax from
the manual and from you, all with the same results as before. From the
management station I get:

sam: Unexpected end of session. It is possible that the SAM request for
'Inhibit  Drop Close src ip <IP addresses> on All' was not enforced.

>From the enforcement point I get:

sam: Server entity initialized failed. The SAM request was not performed.

Yes, I am working on getting the OPSEC messages from Real Secure to enable
SAM (suspicious activity messages) functionality, but if the process does
not work manually, I can't expect it to work programmatically. And, no, the
RS > OPSEC > FW SAM is not working either.

I have put a sniffer on the wires, and the SAM messages are going between
the RS network sensor and the management module. No corresponding traffic is
going between the management module and the firewall enforcement point.

Pointing the RS messages (changing the putkey, etc.) directly to the
firewall enforcement point does not make it work either. Fw sam is just not
doing anything on my firewall.

I have maintenance and support from both ISS and Check Point, so I will be
calling them next; probably CP first. I just wanted to do everything I could
without calling them. Support from any vendor goes through the basics first
(is it plugged in? is it turned on?), and I wanted to be able to say I had
done all that.

Thanks again...

Mick

Hello Mick,

Finally I made it work today. You need NG FP3 HF-1 (at least for my cluster
configuration). In fact it must work on a default instalation. Try this:

fw sam -v -s <fw object name> -D

If you still have the same answer, try to reset sic communication between
the module and management (caution you may lose conection). Reinitialize SIC
comunication and try again.

If you have a success response, then try fw sam -v -D. I hope you to have a
succefull response so that you can configure Realsecure communication.

In the management: fw putkey -opsec <ip realsecure net sensor> (provide a
shared secret twice as requested)

In the RS Sensor: opsec_putkey <ip management> (provide same secret
requested before, twice again)

Afeter that, from the RS Console stop and restar the sensor and that's all.
(check reponses so they are directed to the management, and a good way to
test it is enabling the "email debug" detection)

Finally, if you are unable to get a successful response at the manual
execution of sam commands from the management, think on sic_reset. This
operation is risky but it can be controled ("backup you configuration
first"). This might let you an unusable management and ready to use you
backup.

I hope this can can help you to configure your RealSecure. By the way, as
you only have one module, you can configure RS to interact directly with it,
replace management ip for module ip in the previous procedure, even in RS
responses and it works.

Subject: [FW-1] fw sam error


I am working with OPSEC suspicious activity messages (SAM), trying to get
our RealSecure IDS to originate SAM and CheckPoint NG to respond to SAM. The
next step I need to take is making sure that "fw sam -v -t 60 -i src <IP
address>" manual methods work. Well, they are not. When I enter the
address>above
command at the management console, I get the following error:

sam: Unexpected end of session. It is possible that the SAM request for
'Inhibit  Drop Close src ip <IP addressas> on All' was not enforced.

where <IP address> is a dotted decimal IP address.

I found the article on the SecureKnowledge database "sk8382", but that did
not make any difference, and I am not sure that article applies to my
environment.

VPN-1 NG FP3 (non-HF1), single enforcement point, single management console.
Enforcement point: SecurePlatform, NG FP3, Second Edition (non-HF1)
Management console: Windows 2000 Server, NG FP3 (non-HF1)
