Xferstats is a utility that parses wu-ftpd, ncftpd, and (special) apache
xferlogs and gives various information and totals about the data transferred.
TAYGA is an out-of-kernel stateless NAT64 implementation for that uses the
TUN driver to exchange IPv4 and IPv6 packets with the kernel. It is intended
to provide production-quality NAT64 service for networks where dedicated
NAT64 hardware would be overkill.
From the tcpcat README:
Tcpcat is a simple program that is like `cat' but it works over TCP streams
to allow you to cat from one host to another.
The host common way to use this program whould be something like this:
on host a: $ tcpcat -l 93255 | gzip -dc | tar xvf -
on host b: $ tcpcat -h hosta:93255 file.tar.gz
Another good use for this program is debugging network stuff. When debugging
a newtork client or server you can pipe the output of tcpcat to a hex dump
(I recomend xxd which comes with vim). Also it can act as a crude telnet server
when invoded with --listen, --input, and --output, this mode is quite useful
for network program debugging as well.
Produces a per-protocol breakdown of traffic by bytes and packets,
with average and maximum transfer rates, for a given libpcap file
(e.g., from tcpdump, ethereal, snort, etc.) Useful for getting a
high-level view of traffic patterns.
This is a port of librdkafka, a C library implementation
of the Apache Kafka protocol, containing both Producer and
Consumer support. It was designed with message delivery
reliability and high performance in mind, current figures
exceed 800000 msgs/second for the producer and 3 million
msgs/second for the consumer.
This is the NANOG traceroute program. This traceroute variant offers
features such as MPLS label decode, Path MTU discovery, AS lookup,
and spray mode. It is maintained by a collection of volunteers.
Linphone is an internet phone or Voice Over IP phone (VoIP).
* With linphone you can communicate freely with people over the internet,
with voice, video, and text instant messaging
* Linphone makes use of the SIP protocol, an open standard for internet
telephony. You can use Linphone with any SIP VoIP operator, including
the free SIP audio/video service provided by www.linphone.org
* Linphone is available for desktop computers: Linux, Windows, MacOSX, and
for mobile phones: Android, iPhone, Blackberry
tcpmssd was written by Ruslan Ermilov <ru@FreeBSD.org> based on work
done by Patrick Bihan-Faou <patrick@mindstep.com>.
tcpmssd is a divert(4) program that adjusts outgoing TCP data so that
the requested segment size is not greater than the amount allowed by
the interface MTU.
This is necessary in many setups to avoid problems caused by routers
that drop ICMP Datagram Too Big messages. Without these messages,
the originating machine sends data, it passes the rogue router then
hits a machine that has an MTU that is not big enough for the data.
Because the IP Don't Fragment option is set, this machine sends an
ICMP Datagram Too Big message back to the originator and drops the
packet. The rogue router drops the ICMP message and the originator
never gets to discover that it must reduce the fragment size or drop
the IP Don't Fragment option from its outgoing data.
tcpproxy is a simple TCP connection proxy which combines the features of
rinetd and 6tunnel. tcpproxy supports IPv4 and IPv6 and also supports
connections from IPv6 to IPv4 endpoints and vice versa.
tcpshow reads a tcpdump(1) savefile and provides a reasonably complete
decode of Ethernet, IP, ICMP, UDP and TCP headers. Boolean expressions
may also be specified for packet selection. Data within the packets are
displayed in ASCII.
tcpshow's output is simular to Sun Solaris's snoop(1M) command for
network packet capture and inspection.
