dsc(1) General Commands Manual dsc(1) NAME dsc - DNS Statistics Collector SYNOPSIS dsc [ -dfpmiTv ] dsc.conf DESCRIPTION DNS Statistics Collector (dsc) is a tool used for collecting and ex- ploring statistics from busy DNS servers. It can be used in a distrib- uted architecture to run collectors on or near nameservers sending their data to one or more central presenters for display and archiving. dsc will chroot to a directory on startup and output statistics into files in various formats. See dsc.conf(5) on how to configure dsc, what formats exists, their structure and output filenames. OPTIONS -d Debug mode. Exits after first write. -f Foreground mode. Don't become a daemon. -p Don't put interface in promiscuous mode. -m Enable monitor mode on interfaces. -i Enable immediate mode on interfaces. -T Disable the usage of threads. -D Don't exit after first write when in debug mode. -v Print version and exit. FILES /usr/local/etc/dsc/dsc.conf Default configuration file for dsc SEE ALSO dsc.conf(5) AUTHORS Jerry LundstrA<paragraph>m, DNS-OARC Duane Wessels, Measurement Factory / Verisign Ken Keys, Cooperative Association for Internet Data Analysis Sebastian Castro, New Zealand Registry Services Maintained by DNS-OARC https://www.dns-oarc.net/tools/dsc KNOWN ISSUES This program and/or components uses select(2) to wait for packets and there may be an internal delay within that call during startup that re- sults in missed packets. As a workaround, set pcap_thread_timeout ( see dsc.conf(5) ) to a relevant millisecond timeout with regards to the queries per second (QPS) received. For example if your receiving 10 QPS then you have 20 packets per second (PPS) and if spread out equally over a second you have a packet per 50 ms which you can use as timeout value. Since version 2.4.0 the default is 100 ms.
