RPC Decode

The rpc_decode preprocessor normalizes RPC multiple fragmented records into a single un-fragmented record. It does this by normalizing the packet into the packet buffer. If stream4 is enabled, it will only process client-side traffic. By default, it runs against traffic on ports 111 and 32771.


Table 2.5: RPC Decoder Options
Option Description
alert_fragments Alert on any fragmented RPC record.
no_alert_multiple_requests Don't alert when there are multiple records in one packet.
no_alert_large_fragments Don't alert when the sum of fragmented records exceeds one packet.
no_alert_incomplete Don't alert when a single fragment record exceeds the size of one packet.
