+* Servcheck
+Ever had problem with running services after server reboot?
+This script snaps state of things such as:
+- List of unique processes names
+- List of opened TCP/UDP ports along with proces name
+- Firewall rules dump
+- Routing table 
+After restart, you can use the script to create diff's with latest snaps made, making it easy to find out what isn't working.
