step 1: service snmpd restart
step 2: edit /etc/snmp/snmpd.users.conf and replace public with your actual
snmp community string
step 3: service snmpd restart
step 4: netstat -an | grep 161
for checkpoint snmpd port 260:
step 1: modify the $FWDIR/conf/snmp.C file and place the actual snmp
community inside the read and write (). If you leave the write empty,
it will use "private" as the community string. This is a security risk.
step 2: run sysconfig and start the checkpoint snmpd extension
step 3: perform cpstop;cpstart
step 4: netstat -an | grep 260

The internal_sendmail indicator can be used in any of the script options on the 'Alert Commands' configuration page.
When choosing logging actions in rules or other Gateway logging properties, set the action to correspond to the alert you define on the 'Global Properties > Log and Alert > Alert Commands' property screen.
In SmartDashboard:
Select 'Global Properties > Log and Alert > Alert Commands'.
Check 'Send mail alert to SmartView Status'.
Check 'Run mail alert script'.
Enter script:
internal_sendmail [-s ] [-t ] [-f ] ...
Example (default):
internal_sendmail -s alert -t mailserver_ip mail_account
In the Rule Base, define a rule that will generate an alert. In the Track field, enter 'Mail'.
Install the Security Policy.
Below are some of the various files and commands which you may find useful on a Checkpoint.
Smart Centre Server
$CPDIR/conf - Contains parts of the CPShared system
* cp.license - license of machine
* sic_cert.p12 - SIC certificate
$FWDIR/lib - .def files which are used when the rulebase is complied into inspection code for Enforcement points.
$FWDIR/conf - the rule base and the rest of the security policy can be found here.
* rulebases_5_0.fws - Contains rulebases and duplicate in *.w files
* objects_5.0.C - Contains all the objects. objects.C is created when sent to the Enforcement Points
$FWDIR/conf/fwauth.* - User Database, main file being fwauth.NDB
$FWDIR/conf/masters - Defines the local log definition in Dashboard
$FWDIR/database/fwauth.* - User Datbase, main file being fwauth.NDB
$FWDIR/log - Logs
Enforcement Point
$CPDIR/conf - Contains parts of the CPShared system
* cp.license - license of machine
* sic_cert.p12 - SIC certificate
$FWDIR/conf/discntd.if - Add interfaces you want to show as disconnected for ClusterXL.
Misc
/etc/sysconfig/netconf.C - Used to configure interface as down, this is useful for ClusterXL when interfaces have no link.
I once SSH login alert presented the way to send mail alert after successful login by ssh to any Linux-based machine , including Checkpoint firewalls. Now, thanks to folks at cpug.orgthat draw my attention to it, I will show how to get mail Alert on ANY rule in the security rulebase of the firewall, and also simplified script using Checkpoint version Of the sendmail. e.g. internal_sendmail -s SSH_login_alert -t 63.161.169.140 -f yurisk@yurisk.info president@whitehouse.gov NOTE. Some don'ts
First , rules alerts – on any rule in the Security Rulebase you can set in its Track column toMail . Now all hits
On such rule will be sending mail alerts to specified recipient(s) through the specified mail server (Checkpoint doesn't have a mail server of its own) . So, if you create rule that allows access by SSH you can set in Track Mail and each time this rule is used to access the firewall mail will be sent. Now how to configure mail server settings, you do it in
Policy -> Global Properties -> Log and Alert -> Alert Commands , check " Send mail alert to SmartviewView Monitor" and "Run mail alert script" . In the "Run mail alert script" field set to the string of form:
The mail you get on such alert looks like: 6Jan2010 7:29:55 accept fw-tokyo >External mail rule: 2; rule_uid: {85A905A7-951E-4100-A23A-E280FAAA1D29}; SmartDefense profile: Default_Protection; service_id: ssh; src: my-management-host; dst: fw-tokyo ; proto: tcp; product: VPN-1 & FireWall-1; service: ssh; s_port: 47145;
- You can't send to multiple recepients;
- You can't send using IP of the firewall for the mail server
- The mail server you specify should be the one accepting mails for the recepient's address or be doing
mail relay without authentication. And no, Checkpoint sendmail doesn't support authentication.
" Delete all IPsec SAs for a given peer (GW)" – but it just plain doesn't work. And once confronted with this problem that could make debug more devastating than the problem itself I started looking for alternatives. To much of my surprise CP has a perfect alternative for this
- vpn shell, that provides acceptable means of managing tunnels. Here are details:
vpn shell can : delete IKE/IPsec SAs selectively, add/delete VTI interfaces,show information about all that.
To enter this shell :
[Expert@gw1]# vpn shell
? – This help
.. – Go up one level
quit – Quit
[interface ] – Manipulate tunnel interfaces
[show ] – Show internal data
[tunnels ] – Manipulate tunnel data After hitting enter you are put into subshell that has hierarchy way of moving around, so to continue to show subtree you type show and hit Enter:
VPN shell:[/] > show
? – This help
.. – Go up one level
[interface ] – Show interface(s) and their status
[tunnels ] – Show SA(s)
VPN shell:[/show] > Your prompt changes to the path inside vpn shell, to go 1 level up (return) type .. and Enter:
VPN shell:[/show] > ..
? – This help
.. – Go up one level
quit – Quit
[interface ] – Manipulate tunnel interfaces
[show ] – Show internal data
[tunnels ] – Manipulate tunnel data
VPN shell:[/] > In addition if you know the full path inside vpn shell to the command you wish to run you can type it too: e.g. To see all IKE tunnels:
[Expert@gw1]# vpn shell
? – This help
.. – Go up one level
quit – Quit
[interface ] – Manipulate tunnel interfaces
[show ] – Show internal data
[tunnels ] – Manipulate tunnel data

VPN shell:[/] >
e.g. 2 To delete IKE SAs for specific peer:
VPN shell:[/] > tunnels delete IKE peer 193.3.3.3 NOTE: interface subtree is for dealing with VTI interfaces. And finally to leave the vpn shell to SSH shell:
Get to the root by typing .. as many times as needed and then quit: VPN shell:[/show/tunnels/IKE] > ../../..

According to me, its nothing but a fw command with which we can monitor the heath of your CP box., especially Syc Status.. Am sure that you will love this command and say thanks for CP for this……
Am taking an example to explain the same.. here we go…….
Sync:
Version: new
Status: Able to Send/Receive sync packets
Sync packets sent:
total : 466729198, retransmitted : 241305, retrans reqs : 6089, acks : 809
Sync packets received:
total : 77283541, were queued : 6715, dropped by net : 6079
retrans reqs : 37462, received 175 acks
retrans reqs for illegal seq : 0
dropped updates as a result of sync overload: 0
Delta Sync memory usage: currently using XX KB mem
Callback statistics: handled 138 cb, average delay : 2, max delay : 34
Number of Pending packets currently held: 1
Packets released due to timeout: 18
Explanation:
Version: new
This line must appear if synchronization is configured (versions above 4.1)
Status: Able to Send/Receive sync packets
If sync is unable to either send or receive packets, there is a problem
Sync packets sent:
total : 466729198, retransmitted : 241305, retrans reqs : 6089, acks : 809
TOTAL number of sync packets is non-zero and increasing
RETRANS REQS may increase under load
Sync packets received:
total : 77283541, were queued : 6715, dropped by net : 6079
QUEUED value never decreases - A non-zero value does not indicate a problem
DROPPED BY NET number may indicate network congestion
The "dropped by net" counter is incremented when the cluster member receives a sync packet with a sequence number which is higher than the expected seq num. This means packets with lower seq where lost somewhere along the way, and we need to find out where.
retrans reqs : 37462, received 175 acks
RETRANS REQS growing very fast may indicate that the load is becoming too high
retrans reqs for illegal seq : 0
May indicate a sync problem
dropped updates as a result of sync overload: 0
In a heavily loaded system, the cluster member may drop synchronization updates sent from another cluster member
Delta Sync memory usage: currently using XX KB mem
This statistic only appears for a non-zero value.
It requires memory only while full sync is occurring at other times, Delta sync requires no memory
Callback statistics: handled 138 cb, average delay : 2, max delay : 34
This statistic only appears for a non-zero value.
AVERAGE DELAY should be 1-5 packets, otherwise indicates an overload of sync traffic
Number of Pending packets currently held: 1
This statistic only appears for a non-zero value.
Packets released due to timeout: 18
This statistic only appears for a non-zero value.
If the it is large (more than 100 pending packets), and the "Number of Pending packets currently held" is small, you should take action to reduce the number of pending packets.
To tackle this problem, try google "Reducing the Number of Pending Packets". Read More ...
