Hi guys,
I am trying to finish up the script I created that parsed, and sorted my firewall rules, however, I am having a little problem finishing it up.
In my output, above each policy I always have a "From: To:" line, but since I was able to sort it, this is somewhat redundant in the output. Unfortunately I cannot just sort the file and run uniq on it as that would throw the sorting I painstakingly got working completely off, as well as possibly remove parts of the firewall policies I am trying to get printed out.
Some of the input I am working with looks like this:
From: Wlan To: Untrust-Firn
567 | Any | State Auditor VPN | grp-vpn | Permit | alw-state-vpn
From: Wlan To: Untrust-Firn
594 | Any | Any | GRE | Permit | alw-vpn
| | | grp-vpn
From: DMZ-public To: VPN-cs
506 | Polycom-COB-2320 | aaaaaaaaa-Polycom | H.323 | Permit | alw-polycom
| | | PING
| | | Polycom-Call-Setup
From: DMZ-public To: VPN-cs
517 | Polycom-BB-ConfRm | aaaaaa-Polycom | ANY-4hrs | | alw-polycom
From: Trust-cs To: VPN-cs
351 | Any | Any | Any-to-8-hrs | Permit |
| | | PING
From: Trust-cs To: Wlan
426 | grp-trust-dhcpservers | Any | DHCP-Relay | Permit | alw-dhcp
From: Trust-cs To: Wlan
436 | Any | Any | PING | Permit | alw-ping
| | | SSH
From: Trust-cs To: Wlan
510 | abcd-epicenter.primary.ad | Guest-Router | SNMP | Permit | alw-snmp
| netmon.noc.xxxx.xxx | |
I searched the forums and tried to find an answer in the numerous other postings that dealt with removing duplicate lines but I could not find anything that gave me the exact result.
I tried radoulov's suggestion from another post on my RHEL install:
awk 'x[$0]++' input.txt
but that also removed parts of the firewall policies that I needed to keep.
I am just trying to remove repeated lines such as (keeping the first ocurrance each time):
From: DMZ-public To: VPN-cs
I'd like the final output to look similar to this:
From: Wlan To: Untrust-Firn
427 | Any | Any | POP3 | Permit | alw-pop3
428 | Any | Any | SMTP | Permit | alw-smtp
469 | Alva-T1-FW | Any | ANY | Permit | alw-vp-t1
From: Trust-cs To: Untrust-Firn
533 | Any | grp-untrust-aplia | Aplia (wo 73857) | Permit | alw-aplia-ports
Thank you in advance for any help you can give me. It is much appreciated.
