--- Comment #3 from Eugene Grosbein <eu...@freebsd.org> --- (In reply to Florin Samareanu from comment #2) The problem is more complex. Indeed, "In SNMP some fields are encoded with TLV (Type Length Value), where the length specifies how many bytes to read on the next field" - that's true. But ASN.1/DER encoding standard states that if integer value is small enought to be fit in single byte, it MUST be encoded with single byte and using 4 bytes is not allowed for such case by this standard. snmpwalk can send small or large integers and it encodes them just right using noted "minimal integer" encoding: 1 or more bytes correspongingly. bsnmpd parses both of small and large TLV fileds just fine. On the other hand, ejrh/snmp library used by ntopng ALWAYS encodes integers using 4 bytes, even for small values (R=1 in the test above). That is standard violation that does not pass bsnmpd's strict validation, but pass relaxed validation of net-snmpd. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
