IOG is a network I/O byte grapher made to graph cumulative KB/MB/GB totals for hours/days and months. It is intended to be simple, fast (support thousands of interfaces) and integrate well with MRTG (not required). Data for each host is updated hourly and HTML graphs are created. It uses a data consolidation algorithm which allows for a small, non-growing database file for each host. Perl is required, but no external graphing libraries or binaries are needed.
ipac is an IP accounting package for Linux. It collects, summarizes, and nicely displays IP accounting data. The output of ipac can be a simple ASCII table, an ASCII graph, or even images with graphs showing traffic progression. ipac can be used for IP traffic analysis and for accounting purposes.
The ipaudit package records and displays network activity. It is useful for identifying heavy bandwidth users, intrusive telnet sessions, denial of service attacks, and scans. It includes ipaudit, which stores counts of bytes and packets for every combination of host/port pairs and protocol. The utilities total and ipstrings can be used to investigate network traffic records from the command line. ipaudit-web can collect network traffic statistics and generate Web reports.
iplog is a TCP/IP traffic logger. Currently, it is capable of logging TCP, UDP, and ICMP traffic. iplog is able to detect TCP port scans, TCP null scans, FIN scans, UDP and ICMP "smurf" attacks, bogus TCP flags, TCP SYN scans, TCP "Xmas" scans, ICMP ping floods, UDP scans, and IP fragment attacks. iplog is able to run in promiscuous mode and monitor traffic to all hosts on a network. iplog uses libpcap to read data from the network and can be ported to any system that supports pthreads and on which libpcap will function.
IRCtl is a LIRC-compatible driver for the IR remote control in the FlyVideo98 TV card. There is always a newest version of this driver in the Lirc CVS tree. It is a patch against kernel bttv driver plus loadable lirc driver module. The kernel patch also enables support of the FV98 card in the kernel bttv driver.
