### Intro

Netdisco is an Open Source web-based network management tool.

Here are some of the favorite uses for this tool:

- Find a Switch Port from a MAC or IP address and the reverse.
- Administratively disable a Switch Port while leaving an audit trail.
  (Required ReadWrite SNMP passwords to be configured)
- Quickly provide configuration information for network devices.
- Inventory your network hardware by model, vendor and IOS.
- Control your IP address space; know who uses what IP and when.
- Historical data: know what IP and MAC addresses that are in use, and were in use on what ports.
- Pretty pictures of your network.

Things connected to the network are divided into two categories:

- Devices - Network appliances such as routers, switches, and hubs that support SNMP. Each device has multiple interfaces (ports) and can have IPs assigned to those interfaces.
- Nodes - Anything on the network that has a MAC address that isn't a device. Printers, Computers, Servers, Devices for which we don't have SNMP access.

  See the glossary for more details.

New in 0.95:

New Features:
[] Apache-based HTTP authentication added. [] Apache2 + mod_perl2 support from Manuel Bouyer [1107564] Disable BULKWALK on a per device or per device type basis: bulkwalk_no, arpnip_no, macsuck_no, discover_no use same syntax, see README [1111654] Allow wrap in config file with \ char [969117] Automatically reloads config file in web front end when it changes. [1392968] The map key is now automatically derived from configuration (i.e., entries in node_map) [1107578] Port Control via VLANs [744598] Inventory by subnet - IP Inventory feature improved to dump whole subnets [1107579] The map can be clustered by device Location fields. Thanks to Bjorn Isaksson for the patch. [1393653] Modules for optional features (e.g., NBT) are now loaded when needed, not at startup. [1116552] The devices in the "Choose Device" box on the Admin Panel are now listed in numerical order by IP address, to make it easier to find the one you're looking for. [1116547] Contact field is now searched in the device search. New backend database field time_recent in node database, for nodes that move around a lot, it's the last time this node moved *back* to this device (time_first is the first time ever). Add macsuck_only, arpnip_only, discover_only limits Get SSIDs and channel from wireless base station ports, and display SSID in device port, add SSID inventory and SSID search [1462199] Add SNMP timeout parameter to create_device() [1492791] Added options snmp_force_v* [] pg_all, pg_run, pg_init, pg_back unified into single sql/pg script This script parses netdisco.conf for database settings. [] Add graph_png option to use png output from graphviz
New Devices Supported:
Foundry EdgeIron Nortel Passport/Accelar 1100 and 1200 series Nortel Passport/Accelar 8100 series Nortel Ethernet Routing Switch/Passport 1500 series Extreme Alpine and Summit switches Aruba wireless switches Nortel 2700 series (Airespace) wireless switches Nortel/Bay/Synoptics System 3000 and 281X hubs Juniper
Bugs Fixed:
[1094208] "problemnode" attribute on network map was being overriden by default color settings. [1100029] Nbtwalk whole network bug - would die if couldn't connect to a node. [1107565] Log file was trying to be written not in batch mode. [1109221] node_nbt table not created in 0.94 [1107568] Netdisco will not work with new version of Graph.pm (0.5x) (Stéphane Bernaud) [1242746] The port lastchange time was incorrectly calculated and could be off by the time between the device discovery and the web page view (up to a day, with the default crontab). [1407942] IP Inventory needs to cross-reference device and device_ip [] nbtwalk would crash at the end if there are no nodes to visit. [] Device Inventory by Age wouldn't show the DNS name [1085591] Loading the "Search on Vendor or OUI" list could take a long time if your database was full of bogus nodes [] Nightly backup would crash with a million archived values in node_ip [] Database clean (-K or part of -B) would delete nodes on ports that appeared to be uplink ports except the neighbor wasn't in netdisco. [] Devices discovered from topo file were required to be in database [1580283] Workaround for buggy Net-SNMP perl connectors: turn off bulkwalk if a buggy version is detected. [] Don't work with undefined values if no link speed defined. [] Print errors that would have been absorbed by eval.

### Register

The developers are now maintaining a registry of Netdisco installs. This is mainly for morale boosting purposes, but also helps us direct feature requests to our target audience. One drawback of the Source Forge system is that we have no idea how many people are using the software compared to the number of downloads.

Please spend a minute to let us know you're using Netdisco at http://netdisco.org/register.html.

Netdisco is an Open Source project headed up by developers Eric Miller, Bill Fenner and Max Baker.
