 \fB flowtop\fR { [\fIoptions\fR] }

 .SH DESCRIPTION
-
+.PP
 flowtop is a top-like connection tracking tool that can run on an end host or
 small home router. It is able to present TCP, UDP/UDP-lite, SCTP, DCCP, and
 ICMP(v6) flows that have been collected by the kernel's netfilter connection
 tracking framework, thus no packet capturing in user space needs to be done.
-
+.PP
 flowtop is able to give you a quick overview of current connections on your
 local system, e.g. for debugging purposes or to answer questions like:
-
+.PP
     * If you access website X, what other connections are being opened in
       the background that I'm not aware of?
     * What connections are active that pass one's router?

     * To which countries am I sending data?
     * Are there any suspicious background connections on my machine?
     * How many active connections does binary Y have?
-
+.PP
 The following information will be presented in flowtop's output:
-
+.PP
     * Application name and PID when run on local machine
     * Reverse DNS for source and destination
     * Geo-location information (country, city)
     * Used protocols (IPv4, IPv6, TCP, UDP, SCTP, ICMP, ...)
     * Flow port's service name heuristic
     * Transport protocol state machine information
-
+.PP
 In order for flowtop to work, netfilter/iptables must be active resp. running
 on your machine, thus kernel-side connection tracking is active.
-
+.PP
 flowtop's intention is just to get a quick look over your active connections.
 If you want logging support, have a look at netfilter's conntrack(8) tools
 instead.

 .SH USAGE EXAMPLE
-
+.PP
 .SS flowtop
 Default ncurses output for flowtop that tracks IPv4, IPv6 flows for TCP.

+.PP
 .SS flowtop -46UTDISs

 .SH CONFIG FILES
-
+.PP
 Files under /etc/netsniff-ng/ can be modified to extend flowtop's
 service resolution and lookup information.
-

     * tcp.conf - TCP port/services map
     * udp.conf - UDP port/services map
     * geoip.conf - GeoIP database mirrors

 .SH BUGS
 With a fairly high rate of connection tracking updates, flowtop can become
 unresponsive for short periods of time while scrolling. The right fix would
 be to replace flowtop's connection management backend with a better design
 resp. locking approach. Still on todo.
