FlowSphera 1.5.0 release notes

SNMP v2c and v3. A device can now be polled over SNMP (Settings → Devices → the device → Read interface names and IP addresses over SNMP, off by default). FlowTrack reads the interfaces' names, descriptions, state and IP addresses with prefix (IF-MIB, IP-MIB; IPv4 and IPv6) when the device is saved and then every hour, or at once with Poll now under Interfaces. v3 supports MD5 / SHA / SHA-224…512 authentication and DES / AES / AES-192 / AES-256 privacy. Test SNMP in the dialog polls with the typed settings before saving and names the likely cause of a failure (no answer, unknown user, wrong password).
The device dialog adds the SNMP configuration for the chosen vendor (FortiGate, Cisco, MikroTik, Juniper, Linux) to the NetFlow snippet, filled in with the typed values. The protocol lists offer only what that vendor's agent accepts (RouterOS: MD5 / SHA1 and DES / AES-128; FortiOS: no AES-192; Cisco and Junos: AES-128).
Through device and Path analysis name interfaces from SNMP and show their addresses; the subnets read over SNMP also place devices next to each other on Path analysis. Names and addresses entered by hand still win.
Path analysis without interface addresses shows what the records reveal on each end, as Through device does: the network both ends share, the inside network or the NAT address.
MikroTik's NetFlow snippet exports NetFlow v9 (version=9) instead of IPFIX.
Settings → Devices: interface names or addresses saved within a few seconds of opening the page showed the old values until the next visit.
The installer adds the net-snmp tools (snmp / net-snmp-utils); sudo flowtrack upgrade installs them too. Community and passwords are stored for the service only (/var/lib/flowtrack/snmp.json, mode 600), passed to the tools in a private configuration file (not on the command line) and never sent back to the browser.
