Siteminder installation into Apache

We had a recent installation of Siteminder (Web Access management tool) into our systems and had to be configured into existing apache installation.

Here are some issues which came up and the tips which you could look into:

1. Did you give write permission to "site minder user"? for Apache Conf directory

(<apache_root>/apache/conf). Write permission for  "httpd.conf"  file as well.

2. Created directory "/opt/netegrity".
Ideally this should be created in separate filesystem as a good practice.
This would become much helpful for clustering and promotional model.

3. Add entries in the "load module section" within the Apache "httpd.conf"  file

LoadModule sm_module /opt/netegrity/webagent/bin/
SmInitFile <location of apache>/conf/WebAgent.conf

4. Manually add handlers
# Manually added for siteminder
# Add handlers
# Siteminder .exe #
AddHandler cgi-script .exe
# Siteminder .fcc
AddHandler smformsauth-handler .fcc
# Siteminder .sfcc
AddHandler smsslformsauth-handler .sfcc
# Siteminder .scc
AddHandler smadvancedauth-handler .scc
# Siteminder .ccc
AddHandler smcookieprovider-handler .ccc

5. Did you add "Alias" entries from httpd.conf.
Be careful the apache installation MAY NOT restart until unless you have the mod_alias installed

6. Add entry into  "<apache_root>/apache/bin/apachectl" file.
# Entry made as per siteminder installation document
export EXTSHM=ON
[[ -r /opt/netegrity/webagent/ ]] && . /opt/netegrity/webagent/

Please note, that this shell level export won't be killed normally. Hence chance of accumulating such process is high.
ps -ef | grep LLAWP

to find any zombie processes which are being run and kill them off if you encounter below error...

(67)Address already in use: make_sock: could not bind to address [::]:443
(67)Address already in use: make_sock: could not bind to address
no listening sockets available, shutting down

So kill the identified process and restart again.
kill -9 <processid>
apachectl -k stop
apachectl -k start

Issues you might encounter: Not able to shutdown LLAWP process which prevents Apache to restart

If I try shutting down
# LLAWP /opt/apacheinstallation/apache/conf/WebAgent.conf -APACHE20 -shutdown

The process was running at the time of above shutdown command.

The only workaround I was able to do is to
1. Kill the LLAWP process    # kill -KILL $pidofLLAWP
2. Remove all the shared memory and semaphores from the system
# Bit dangerous: kill shared memory of LLAWP
ipcs -m | awk ' $5 == "nobody" {print $2}' | awk '{ print $1}' | while read sharedMemory; do
sudo su - -c "ipcrm -m $sharedMemory"

# To kill all the semaphores
ipcs -s | awk ' $5 == "nobody" {print $2}' | awk '{ print $1}' | while read semaphore; do
sudo su - -c "ipcrm -s $semaphore"


Found a solution for above Problem.

Create another directory say "some_New_directory" within the "<apache_installation_dir>" and specify this as the "ServerPath" in WebAgent.conf

Syslog Standards: A simple Comparison between RFC3164 & RFC5424

Syslog Standards: A simple Comparison between RFC3164 (old format) & RFC5424 (new format) Though syslog standards have been for quite long time, lot of people still doesn't understand the formats in detail. The original standard document is quite lengthy to read and purpose of this article is to explain with examples Some of things you might need to understand The RFC standards can be used in any syslog daemon (syslog-ng, rsyslog etc.) Always try to capture the data in these standards. Especially when you have log aggregation like Splunk or Elastic, these templates are built-in which makes your life simple. Syslog can work with both UDP & TCP  Link to the documents the original BSD format ( RFC3164 ) the “new” format ( RFC5424 ) RFC3164 (the old format) RFC3164 originated from combining multiple implementations (Year 2001)

Elastic Beats on pfSense : Installation and configuration

Summary Though in many cases syslog is preferred to transport the pfSense logs to external system, Elastic beats provides quite a niche way to send the logs while modelling the data alongside. This makes it ready-made to send to ElasticSearch directly and get ready-made outcomes like SIEM, performance etc. Pre-reqs A build server (preferably Ubuntu or Fedora) with internet connectivity shell access to pfsense server Basic knowledge of Elastic Stack (filebeat.yml configurations etc) Ensure connectivity is allowed from pfsense machine to your Elastic Stack receiver Setup Summary Connectivity tests Install dependencies in build server (vagrant, virtualbox, gmake, go etc) Download Elastic Beats source Make elastic Beats package for FreeBSD Copy binary packages to pfsense server Configure Beats to send to destination Configure ElasticSearch to view the data Installation Steps Connectivity tests Logon to pfsense server via Shel
