Syntax
ipfilter [ -f [ u n t x c a ] ] [ -s [ u n t x c a ] ] [ -n [ -d milliseconds ] ] ipreport_output_file
Description
The ipfilter command extracts specific information from an ipreport output file and displays it to a table. The operation headers currently recognized are: udp, nfs, tcp, ipx, icmp, atm. The ipfilter command has three different types of reports:
- A single file (ipfilter.all) that displays a list of all the selected operations. The table displays packet number, Time, Source and Destination, Length, Sequence #, Ack #, Source Port, Destination Port, Network Interface, and Operation Type.
- Individual files for each selected header (ipfilter.udp, ipfilter.nfs, ipfilter.tcp, ipfilter.ipx, ipfilter.icmp, ipfilter.atm). The information is the same as ipfilter.all.
- A file nfs.rpt that reports on nfs requests and replies. The table contains: Transaction ID #, Type of Request, Status of Request, Call Packet Number, Time of Call, Size of Call, Reply Packet Number, Time of Reply, Size of Reply, and Elapsed millisecond between call and reply.
