#Some small network related scripts To get started: ./setup.sh

This will install wireshark, tshark, cpanminus and carton globally and then
add the current user to the wireshark group and install various perl libraries
locally

##iosToHtml.pl Convert an IOS/NXOS/ACE/ASA config file into basic HTML, creating links between commands referencing lists and that list (e.g. access lists, route maps, prefix lists, service-policies etc etc).

Will also link between files for various things (route next hop, interface
subnets etc) for all files in the set you're analyzing

Very useful for trying to follow the flow of complex configurations and to
point items that are defined but never used

e.g.:
	./iosToHtml.pl -e -h -f -s ./sample_configs/*.cfg
	
Items highlighted in orange are unused in this config

Example 1

Example 2

##annotate_hosts_and_networks_in_file.pl Parse a text file (router config, ACL etc etc) containing host and/or wildcard mask entries and test reachability for each host and network mentioned in it. Create simple HTML output with in-line color coded anotations for everything found (status, host count etc)

Can also use a list of known BGP networks (see bgp_asn_path_via_snmp.pl to create it) 
to test whether a network is specifically known 

##create_host_info_hashes.pl Create a hash used by iosToHtml.pl to allow linking between configurations Automatically called by iosToHtml.pl as needed.
Delete "host_info_hash.stored" to recreate it for new or additional files

##tcpSplit.pl Splits an input pcap capture file into a separate file for each stream using tcpdump Much faster than extractTcpStreams.sh

##tcpStatistics.sh Use tshark to print some statistics about a given pcap network capture file.

##aclUsage.pl Tally up overall ACL hits from Solarwinds Network Configuration manager output of Cisco IOS "show ip access-lists" for multiple devices

##splitNcmOutputIntoFilePerDevice.pl Split an input Solarwinds Network Configuration manager output log into a separate file for each device

##bgpAsnsFromConfigs.pl Make a graphviz diagram of how BGP ASNs interconnect from a bunch of Cisco config files (sorry, no Juniper etc. yet)

##parseMlsQosInterfaceStatistics.pl Parse the output of "show mls qos interface statistics" from a Cisco Catalyst 3560/3750 switch Combines the counts of all of the interfaces to get an idea of the overall mix of incoming/outgoing COS/DSCP values and which queues are queuing and dropping the most packets

##parseRiverbedInterceptorRules.pl Parse some rules from Riverbed Interceptor configurations into an Excel spreadsheet to make reading/organizing them easier

##extractTcpStreams.sh Splits an input pcap capture file into a separate file for each stream using tshark Currently the name format is "stream ID - source IP - destination IP - destination port"
