NAME

APRECV - APSR network testing tool designed to receive arbitrary packets  

SYNOPSIS

aprecv [options]  

DESCRIPTION

APRECV is designed to receive and analyze arbitrary network packets or complete protocols. A complete list of currently supported protocols can be found in the PROTOCOLS section.

APRECV supports alot of command line options to control the packet sniffing engine, BPF filters, the output format, statistics and various error checks. Please have a look at the OPTIONS section.

Every non-printable characters in the payload field of the different protocols will be replaced by a ".".

 

OPTIONS

--calc-checksums
Recalculate the checksums of the sniffed packets (if any) and print the correct one if it's wrong. Currently only IPv4 and ICMPv4 are implemented.
-c | --count
Count the size of the received packets.
-d | --device <device>
Listen on device. If no interface is given, APRECV tries to autoselect one (excluding loopback devices). On some systems you can use "any" to listen on all interfaces at the same time.
-D | --daemon
Run APRECV in daemon mode (fork in background and exit).
--expand-<protocol>
Expand the protocol header and display all protocol header fields verbosely. Following options are available: --expand-all, --expand-ethernet, --expand-arp, --expand-token, --expand-llc and --expand-pppoe.
-f | --filter filter rule
Set up a BPF filter rule.
-F | --filter-nopt filter rule
Set up a non-optimized BPF filter rule.
-h | --help
Display a help message and exit.
-I | --iptrace-file <file>
Read an iptrace dump file, can be gzipped.
-l | --logfile <file>
Write all received packets wich are normally printed to STDOUT to a file. If the file doesn't exist, APRECV will create a new one, otherwise it will append the information.
--max-packets <num>
Maximum number of packets to receive, default is a endless loop.
--module <file>
Load a shared module.
--modules <directory>
Load all shared modules in this directory.
--module-ignore
Ignore the builtin BPF filter of the module.
--print-<protocol>-hex
Print the payload of a packet in hex. The following options are available: --print-ip-hex, --print-pppoe-hex, --print-tcp-hex and --print-udp-hex.
--print-<protocol>-text
Print the payload of a packet in text. The following options are available: --print-tcp-text and --print-udp-text.
--print-tcp-stream
Print captured TCP streams out.
-p | --promisc <0|1>
Enable or disable promiscuous mode for the device (0=off, 1=on). The promiscuous mode is useful in ethernet networks to receive packets which are not sent to the MAC address of your network interface.
-P | --pcap-file <file>
Read a raw pcap dump from a file.
--quiet
Close the stdout filehandle, useful with raw logfile mode, but print out errors.
-r | --logfile-raw <file>
Log all packets in raw format to a file.
--really-quiet
Close the stdout and stderr filehandle, useful with raw logfile mode.
-R | --print-raw-hex
Print raw packets in hex.
--server-addr <ip>
IP Address of the APSR-Server, to connect to.
--server-port <port>
Port number of the APSR-Server.
-s | --snaplen <up to 65535>
Set the snaplen for pcap, default is 65535.
--statistic
Print a statistic of all counted packets and protocols before terminating. Format: NORMAL_COUNT (TRUNCATED_PACKETS|ERRORS_IN_PACKETS).
-S | --snoop-file <file>
Read an snoop dump file, can be gzipped.
--use-apsrlib
Use the APSRLib instead of Libpcap. Some options may be disabled or not useable.
-v | --verbose
Print more information about the protocols, the interface, the localnet and the netmask address and activate resolving of IP and MAC addresses.
-V | --version
Display the APRECV version and the compiled libpcap version.
