This command will show you the pre-shared-key configured on your ASA

Small reminder as I always tend to forget these :

Dump the CRM cib db :

cibadmin -Q > cib.backup.xml

Modify a resource , dump the cib, modify the xml for the resources and then import using cibadmin -M

cibadmin -V -M -o resources -x modified_resources.xml

Add a resource , create the xml for the resource and them use -C

cibadmin -V -C -o resources -x new_resource.xml

Move resource from one location to another, -f to force it …

crm_resource -M -r resource -H host
crm_resource -M -r resource -H host -f

If you dont like using telnet to test a remote or local smtp server , swaks is a neat little tool to do the job for you.
its also available ( suprise suprise … ) in the freebsd ports : /usr/ports/mail/swaks.

found it first here

1. Allow only specific ip address :

order allow,deny
deny from all
allow from 192.168.1.1
allow from 192.168.1.2

2. Block specific ip address :

order deny,allow
allow from all
deny from 192.168.1.1
deny from 192.168.1.2

you can substitute ip for :

subnet -> deny from 192.168.1.0/24
subnet wild cards -> deny from 192.168.*.*
domain -> deny from domain\.com

you can also combine ip’s on one line:

deny from 192.168.1.1 192.168.2.1
