NAME

udplogger - Log start of UDP sessions  

SYNONPSIS

udplogger [-i if] [-a|-b] [-f file] [-n]

 

DESCRIPTION

Udplogger is the UDP equivalent to tcplogger(8). It is used to log the UDP sessions that traverse a network. This is accomplished by putting the network interface into promiscuous mode and reading all UDP packets. A table is maintained of all "active" UDP sessions. Only new sessions are logged. Udplogger currently only runs on SunOS 4.x machines.  

OPTIONS

-i
Specify the interface to listen for UDP packets on. This defaults to the first interface.
-a
Log output records in ASCII.
-b
Log output records in binary for use with the extract(8) command. The format of the record is 

        struct timeval  tm;   /* Time of request */
        u_long ipsrcaddr;     /* IP source address */
        u_long ipdstaddr;     /* IP destination address */
        u_long seqno;         /* Always zero */
        u_short udpsrcport;   /* UDP source port */
        u_short udpdstport;   /* UDP destination port */

-f
Specify the file where output records should go. The file is opened for appending. If not specified, output goes to stdout.
-n
Don't do any hostname or port name lookups. Print out everything in decimal or dotted decimal format.
