CHANGES File for IPTraf 2.7.0 Changes to IPTraf 2.6.1 and new features in IPTraf 2.7.0 Corrected bug wherein the detailed interface statistics did not filter out the packets based on the selected interface. Thanks to the members of the mailing list for this. Corrected minor interface name comparison bugs in the general interface statistics and TCP/UDP service statistics. Corrected stale locks when IPTraf did not start due to an improper terminal size. Added support for additional DVB interfaces sm2*, sm3*, penta*. Added support for wireless LAN interfaces (wlan*, wvlan*). Fixed segfault that occurs when /proc/net/dev is empty or contains no active interfaces. Thanks to Chris Armstrong for actually trying it out. Added error box to handle the /proc/net/dev error condition mentioned above. Added error box when tx_operate_listbox is invoked on an empty list. Changes to IPTraf 2.6.0 Corrected a segfault in the IP traffic monitor and TCP/UDP service breakdown when a sort is attempted on an empty screen. Thanks to for the report. Corrected segfaults in the TCP/UDP service monitor when scrolling using PgUp and PgDn (or space and '-'). Thanks to Ross Gibson . Corrected post-sorting PgUp problem in TCP/UDP monitor. Corrected inaccuracies in the IP traffic monitor's TCP byte counts and flow rates. *** THE BUG ADDRESSED BY THIS CORRECTION DEFERS IPTRAF 2.6.0. *** Adjusted black-and-white color scheme. Minor adjustments to the printlargenumber() function. Minor cosmetic adjustments. New features in IPTraf 2.6.0 and changes to IPTraf 2.5.0 Added support for Token Ring interfaces. Thanks to many people for help with patches and testing, including J. Kahn Koontz , Dan Seto , and Tomas Dvorak . Added support for sbni long-range modem interfaces (Dmitry Sergienko ). Added support for Free s/WAN IPSec logical interfaces (Doug Nazar ). Code cleanup. Got rid of an ugly goto in itrafmon.c. I hate goto no matter what. Moved write_timeout_log.c to tcptable.c. Recoded the PgUp/PgDn routines in the IP traffic monitor, TCP/UDP service monitor, and LAN station monitor. These routines now directly manipulate the table pointers instead of merely calling the single-line scrolling routines repeatedly. Faster. More efficient. Added a highlight bar to the IP traffic monitor, allowing better readability, especially on long-line screens (> 80 characters), and individual flow rate computation. Added flow rates for the highlighted TCP flows (IP traffic monitor) and TCP/UDP ports (TCP/UDP statistical breakdown) I believe this is the best way to allow viewing of data rates without excessively sacrificing CPU time for packet capture. Filters now apply to all facilities except the packet size breakdown and LAN station monitor. You can now view the loads and protocol breakdowns on selected packets only using the filters. No more byte counters in the IP traffic monitor. This line now just contains a simple packet counter at one end, and the TCP flow rate information at the other. Moved menu, selection listbox, and dialog box functions to a separate support/ directory. These routines are first compiled into a library and later on linked into iptraf. Added a confirmation box to the main menu's Exit command. This is as much for me as it is for a lot of people. I accidentaly exit too. Added broadcast packet and byte counts to the detailed interface statistics log. Some cosmetic adjustment. Added 5-minute timeout for rvnamed child processes. New features in IPTraf 2.5.0 and changes to IPTraf 2.4.0 Now includes a more specific dialog for non-TCP and non-UDP filters. Allows specification of packets by source and destination IP addresses. Better organized the filter management and manipulation functions in fltedit.c, fltselect.c, othipflt.c, and utfilter.c. othfilter.c renamed to fltselect.c, same thing with the .h. All filters are now unified in a single data structure allowing handling of TCP, UDP, misc IP, and non-IP toggles with one set of functions. Separate TCP and non-TCP filter menus abolished, everything is now grouped under a Filters... submenu under the main menu. Corrected wrong placement of timer in the packet size breakdown. Corrected scanning code for timed out entries in the IP traffic monitor sort function. Wrong computation for elapsed time resulted in active connections being placed in the list of closed entries. Thanks to Gal Laszlo for pointing out the symptom. Added support for Frame Relay FRAD/DLCI interfaces. Thanks to Raffaele Gariboldi for the information and testing. Sorting is now done with the Quicksort algorithm. IP Traffic Monitor now adds connection entries to the TCP window upon the receipt of header-only packets. There are cases in which we have to check for possible TCP scans which are implemented with non-SYN packets. The reverse DNS lookup function revname() now times out after five seconds, and stops reverse lookups for that session in case rvnamed dies. Added some notes to the packet size breakdown window. Moved rvnamed cache index update code such that updating of the cache indexes will only be performed once fork() succeeds, otherwise, the allocated slot will just be reallocated for the next queries. This is so that should the fork() fail, future invocations for that IP address won't have the rvnamed parent thinking its resolving when there actually wasn't a child performing the resolution. If the fork() problem condition was temporary, the next invocation can still have rvnamed fork() off to resolve the address. This of course assumes the IP address hasn't expired from the cache. Some cosmetic updates (as always). The manual features a new format for the sidebars. Corrected typos and spelling errors. iptraf-x.y.z.tar.gz no longer comes with precompiled binaries. However a separate iptraf-x.y.z.i386.bin.tar.gz will come only with the precompiled x86 executable programs (i386/glibc-2.1/ncurses-5.0). New features in IPTraf 2.4.0 and changes to IPTraf 2.3.1 This version now allows multiple instances of the same facility in different processes, but only one instance can monitor an interface. Please see the RELEASE-NOTES file. As a consequence of the above changes, the default names of the logfiles then reflect the instance or interface being monitored. See the RELEASE-NOTES file. Implemented a dialog box allowing the user to log to a custom log file. Implemented -L command-line parameter to allow specification of the log file name when IPTraf is started with the -B parameter. Removed hardcoded UNIX-domain socket name bound by IPTraf, instead a socket name is generated from the current time and pid. Also removed hardcoded socket name in rvnamed, to which it directs replies to IPTraf. rvnamed still binds to hardcoded socket names though. IP Traffic Monitor can optionally display the source MAC addresses for LAN-based packets. Added appropriate configuration item. IPTraf now reads /etc/ethers in addition to its own database of MAC addresses. Thanks to Frederic Peters for the patch. Moved time-related configuration items to a Timers... submenu to save on screen space. The version.h file no longer exists, rather, a plain version file is in place containing merely the version number. The Makefile reads this file, determines the target machine information and passes this data to the compiler with -D parameters. Imposed an upper limit of 200 on rvnamed child processes. rvnamed should really not go runaway with a normally-functioning DNS server, but I had the good fortune of experiencing a dead DNS server while monitoring. Took my machine down real fast. Precompiled executables now require glibc-2.1 dynamic libaries. Included a Setup installation script to ease somewhat the installation process (installation can still be done the old way though). Cosmetic/color changes. Reflected changes to manual. Changes to IPTraf 2.3.0 Fixed segfault bug when sorting is attempted on an empty TCP window. Thanks to Ramon van Elten for the report and for the assistance in diagnosis. Fixed cosmetic error (sort progress window doesn't disappear) when attempt is made to sort a TCP window with only 1 entry. Thanks again to Ramon for the report. Updated some comments. New features in IPTraf 2.3.0 and changes to IPTraf 2.2.2 Implemented sorting in the IP traffic monitor, TCP/UDP statistical breakdown, and LAN station monitor. Great thanks go to Gal Laszlo for the patch. (Note to Gal: I had to do a heck of a lot of overhaul, and had to implement a clearer screen design, but your patch provided the basis :) Thanks a lot.) Implemented better bounds checking in the text input routine. Added information boxes to TCP/UDP delete and detach filter functions. Added recognition of GRE packets. Modified non-TCP display filters accordingly. Fixed bug in unrecognized IP display and filter code. Added filter item for unrecognized IP packets. Removed leftover code from the old warning on IP masquerading. Reflected changes and corrected typos in manual. Changes to IPTraf 2.2.1 Fixed recognition problem with DVB interfaces. Fixed small buffer overrun in TCP timeout log routine, which can cause a segmentation fault under certain conditions. Minor cosmetic adjustment in TCP connection window. Changes to IPTraf 2.2.0 Fixed segfault in IP Traffic Monitor due to packets from an unsupported link type. Fixed segfault in promiscuous mode management module in the (rare) case of a failure to save or load the interface flags from the temporary storage files. Normally due to a bad installation. Thanks to Udo A. Steinberg for the report. Added support for Ethernet-emulated FDDI interfaces. Thanks to Udo A. Steinberg for the report and help with the testing. Added support for DVB interfaces, thanks to Alex for the notification and the help. Replaced inet_addr() references on filter address entries with inet_aton(). This fixes failure of filters on packets with 255.255.255.255 in their source or destination address fields. Thanks for Peter Magnusson for the report and the test environment. Overhauled TCP/UDP editing facility. Fixed bug wherein garbage entries remain in the filter's parameter list even if an insert/ add dialog is aborted. Fixed detailed interface statistics logging bug (activity and packets-per-second figures were the same). Apologies to Dustin Trammell for my failure to credit him for his report on the behavior of IPTraf on bridges. Changes to IPTraf 2.1.1 and new features in IPTraf 2.2.0 Immediate flushing of disk buffers after a log file write to better accomodate separate logfile parsing scripts. Addition of a manual and automatic clearing of closed and idle TCP entries in the IP Traffic Monitor Added a TCP closed/idle persistence configuration option to control the TCP closed/idle clearing interval. Clarified TCP timeout logfile entries. Saves the state of the interface flags at startup of a facility, and restores them on exit, allowing interfaces previously set to promiscuous mode to retain that state. Important on bridges. Thanks to Dustin D. Trammell and Holger Friese for the patch. However, I had to modify it a little more than a bit and had to overhaul quite a good deal of the rest of the software to better accomodate multiple instances. Promiscuous mode is set only when a facility is started, and restored when it exits. Promiscuous mode is no longer forced at menus. Restoration is not performed though if there is still another facility running, but the interface state remains saved. Fixed a minor bug in the LAN station monitor. The raw socket is now closed when the facility exits. duh. Fixed rare bug in the packet size distribution. The lock file didn't get deleted if the raw socket open failed. Changed the promiscuous mode option to "Force promiscuous". Cosmetic. Added PID's (a la syslog) to daemon log entries. Minor cosmetic adjustments. Changes to IPTraf 2.1.0 Fixed bug in the packet size statistical breakdown. The facility didn't filter packets based on interface name, thus causing inaccurate counts on systems with multiple network interfaces. Fixed a few minor cosmetic errors. Corrected some typographical errors in the manual. Added a FAQ (or the beginnings thereof). Added a spec file for RPM generation. Thanks to Dag Wieers . I'm not a really good RPM'er beyond RPM installation and removal. :) Changes to IPTraf 2.0.2 and new features in IPTraf 2.1.0 Added non-IP to the display/logging filter selections Added interface selection to the IP Traffic Monitor and LAN Station Monitor (with an "All Interfaces" option). Related to the above: now requires an interface name as an argument to the -i and -l command-line parameters. 'all' may be specified for monitoring all interfaces. Added -B command-line parameter to fork program into the background solely for logging purposes. Several people had requested this. Corrected TCP/UDP filter file placement error. Included cfconv program to move files to the proper place. Added program-wide Ctrl+L sequence to redraw the screen if corrupted by outside factors (write, talk, syslog). Added TCP/UDP filter editing facility. Corrected several possible buffer overruns in TCP/UDP filter module. Corrected errors and reflected changes to manual and man pages. Changes to IPTraf 2.0.1 Fixed a rarely-occuring but nevertheless severe segmentation fault bug when long hostnames are coupled with long service names. Great thanks go to Ronald Wahl for the advice and the help. Ron, I'm really gonna find the time to do the code the Right Way :) Changes to IPTraf 2.0.0 Fixed minor non-IP byte count bug in detailed interface statistics. Fixed minor cosmetic bug causing elapsed time indicator to appear in the wrong line on screens not containing 25 lines. Thanks to Uwe Storbeck for the patch. New features/changes in IPTraf 2.0 from 1.4.2 Now uses the new PF_PACKET socket family as its packet capture mechanism. Requires Linux 2.2. Added target/source IP addresses in ARP packet request/reply packet entries in the IP traffic monitor. Also added target/source MAC addresses to RARP request/reply entries. Reorganized menu structure, see the README file for details. Moved packet counts by size to a facility of its own. Added corresponding -z command-line option. New incoming/outgoing packet and byte counts and activity rates in the detailed interface statistics facility. Corrected a bug in the FDDI packet parsing code (wrong link type). Added a check for the IFF_UP flag when generating interface lists, to omit inactive interfaces (but still in /proc/net/dev). This covers the General Interface Statistics and all interface selection lists. Now uses the maximum number of columns on the screen. High thanks to Michael "M." Brown for the patch. Saved me a lot of tedious work. :) Reformatted TCP screen to show only one hostname:port per line, with connections indicated by the green "brackets". I think that's clear enough. Added ARP/RARP opcode and target addresses in the ARP/RARP indicator lines. Added vertical scrolling to the lower (non-TCP) window in the IP traffic monitor to allow for long lines (ICMP, OSPF, some UDP). Allowed for slightly longer host names in the lower IP traffic monitor window. Still increased the rvnamed cache size to 2048 entries. Miscellaneous cosmetic changes. Manual now includes screen shots and comes in HTML format only. Changes to IPTraf 1.4.1 Fixed SEGV condition when attempts are made to load a filter list application or deletion with a zero-length filter list file, which could be caused by deleting the last filter. Thanks to Daniel Savard for the report. Makefile comes with the -m486 option commented out Changes to IPTraf 1.4.0 Moved configuration status window to unobscure a long menu option. Changes to IPTraf 1.3.0 and new features in 1.4.0 Support for PLIP interfaces. Support for other ISDN encapsulations (specifically raw IP and Cisco HDLC) high thanks to Gerald Richter for the information and testing. Added -q parameter to suppress the 1.3.0 masquerading warning for users who wish to automate the various facilities from their inittab and similar non-interactive fashions. Incorporated into the Debian version of 1.3.0 by Debian maintainer Frederic Peters (, carried over to general release 1.4.0. Added an option to change activity indications between kbits/s and kbytes/s. On a suggestion by Paul G. Fitzgerald . Incorporated more flexible compile-time control of directories for configuration, log, and other files. Thanks to Stefan Luethje for the patch. Corrected minor flaws in the default screen update delay code (visually insignificant), that led to occasional skips of the delays. (Call it nitpicking if you will. :)) Moved signal() calls to after terminal checks in iptraf.c, allowing standard behavior of signals when error/warning messages may still be sent to stderr. Allows the user to break out of it with Ctrl+C at the terminal warning if so desired. Reformatted IP traffic monitor log entries on Gerald Richter's suggestions for easier processing with Perl scripts. Included logfile rotation with the USR1 signal. Again on Gerald Richter's suggestion. Moved first-instance tag sequence to after the initscr() call. Indicated IP fragments with no additional information in the lower traffic monitor window. Datagram size, addresses, and interface are still indicated. Changed Non-IP count in IP traffic monitor to byte count (including data-link header lengths) from packet counts. Consistency purposes. Added some extra information for certain non-IP packets. These may eventually grow, but not in too much detail, since this is an IP-oriented utility. Thanks to David Harbaugh for the patch. Removed bind() operation on raw socket to address a condition in which the detailed interface statistics and TCP/UDP statistics stop counting if an interface goes down then up again. This will be studied further. Symptom report sent in by Roeland Jansen . Changed Ethernet/FDDI/PLIP description file formats from binary to plain text, allowing database appends. Other files (configuration and filters) are still binary. On a suggestion by David Harbaugh . Copied IP and upper-layer headers and some data from Ethernet, PLIP, FDDI, and loopback frames into an aligned buffer. Avoids SIGBUS on picky systems (like SPARCs) and general alignment problems. I don't know yet which is worse, the overhead of a 96-byte transfer or the performance hit with misaligned reads. Thanks to Jonas Majauskas for reports and tests. Replaced __-type references with u_int-type references. Increased cache array size in rvnamed to 1024 entries from the previous 512, to better handle combinations of busy networks and slow DNS servers. Cleared up a few instructions in the Makefile, thanks to Arjan Opmeer New features in IPTraf 1.3.0 and changes to IPTraf 1.2.0 Experimental FDDI support. High thanks to Paonia Ezrine for the initial tests on the FDDI code. More feedback is requested on the FDDI functionality. Bugs may still be present. Reestablished ippp interfaces (synchronous PPP over ISDN) after reports that the ISDN problem was fixed with Linux 2.0.34. Fixed fragmentation oversight in TCP/UDP service monitor. Applied the bind() system call to the raw socket to have the kernel filter out packets from interfaces we're not interested in. Makes for better capture times on multiple-interfaced machines. However, a strncmp() is still performed on the returned interface name to counter the race condition between the socket() and bind() calls. Fixed interface statistics print routines to print unsigned rather than signed numbers. Added additional option to adjust screen updates. Useful for IPTraf sessions run on remote terminals (thanks to Lutz Vieweg for the suggestion and Dean Gaudet for the base patch. I modified it a bit, Dean.) Discovered terrible performance penalty due to screen refresh with heavily loaded LAN segments. Therefore, with the new screen update interval option set to 0, all facilities have a 50 ms delay between refreshes (exception: the LAN station monitor has a delay of 100 ms). This is still visually fast (although updates look kinda slower), but this gives more time to packet capture, therefore increasing accuracy and capture performance. Thanks to everyone who responded to my request for advice on this matter and to Ronald Wahl for giving me the symptom report. Modified IP traffic monitor to mark TCP connection entries for reuse once one side is fully closed and acknowledged ("CLOSED" on the screen) and the other closed but even if not acknowledged ("DONE" on the screen. This is because many times, the last ACK gets lost. Included an additional parameter used together with the other command-line arguments to specify an amount of time for which the selected facility would run before automatically terminating (on a suggestion by Linux HOWTO coordinator Tim Bynum . Supplemented the main data structure for the IP traffic monitor with an open hash table for increased search efficiency, especially after the facility has been running for quite some time (the other facilities, which don't grow as much still use linearly-searched linked lists. I'll probably hash them depending on feedback.) Fixed rare bugs in various facilities that caused IPTraf to attempt to proceed even in the event of a raw socket open failure. Fixed SEGV condition when IPTraf is invoked with a command-line parameter that cannot be parsed with getopt(). Added labels to LAN address description selection box. Fixed unsightly LAN address description dialog scrolling. Added a separator feature to the menurt.c module, allowing separation lines within menus. Added separator lines between related groups of menu items in both main and configuration menus. Changed the Options main menu item to Configure. Added the space bar and the '-' key as "unofficial" alternates to the PgUp and PgDn keys (it's not in the manual). Transferred Ethernet description facility option to the Configure submenu, and added a related facility for FDDI addresses. Removed Ethernet-specific references where FDDI and (potentially) other LAN technologies also fit. We'll just use "LAN" as a general term. Adjusted detailed statistics screen to automatically generate the appropriate packet size distribution brackets based on interface MTU. This means the brackets may no longer end on numbers divisible by 10, but rather on boundaries based on the MTU divided by 16 (the number of brackets). But at least 1500 is not hardcoded anymore as the maximum. Related to the immediately preceeding change: packet size distribution updates are done one at a time now, no longer as a whole bunch. In other words, as a frame arrives, only the appropriate bracket is updated. Also related to previous two: changed basis for packet size distribution to the Ethernet frame length from the IP datagram length (which really doesn't matter except for a few frames). Fixed bug which causes the existing log interval to multiply by 60 when the dialog is aborted (instead of retaining the current setting). Thanks to Chris Higgins for the bug report and the patch. (I had to modify it a bit to fit in with the screen update interval patch sent in by Dean Gaudet.) Potentially large counts have been changed to type "unsigned long long" to significantly increase running time on heavily loaded networks, plus automatic switching of denominations (from exact counts to K(ilo) to M(ega) to G(iga) to T(era)) to prevent screen disruption (on a suggestion by Lutz Vieweg ). Separated log file into different logs for each facility. Moved log files to /var/log/iptraf to avoid mixing them with the mess in the /var/local/iptraf directory. At least that way, we humans don't have to look in /var/local/iptraf anymore. Relaxed multiple-instance restriction from a no-multiple-instances-of-IPTraf requirement to a no-multiple-instance-of-the-same-facility. In other words, several copies of IPTraf can run, but only one instance of each facility can run at any one time. The -f parameter removes the tags, overriding the restrictions on that IPTraf instance. This modification was done to address needs indicated by Chris Panayis ). Added a startup warning box if IPTraf detects IP Masquerading enabled on the computer. IPTraf will continue to work, but its results may be quite confusing. The detection is done by opening /proc/net/ip_masquerade. Modified additional port facility to accept ranges of ports rather than several single port numbers (on a suggestion by Lutz Vieweg ) Reduced minimum number of lines from 25 to 24 for better VT100 terminal compliance. Miscellaneous cosmetic retouches. (I consider user interface an important factor too, ya know! :) Distribution binary now comes statically linked with ncurses 4.2. You may recompile to suit your system. Included manual pages derived from the Debian GNU/Linux 2.0 distribution. Man pages written by Frederic Peters who is now maintaining the Debian IPTraf package. Reversed version order (newest first) in the CHANGES file. New features in IPTraf 1.2.0 and changes to IPTraf 1.1.0 Increased buffer size in ifstats.c for /proc/net/dev lines to 161 to better accomodate the longer lines in the new 2.1.x kernels (which will be carried over to the new stable kernel series). Based on bug reports by Dop Ganger and Christoph Lameter et al. Fixed rarely occuring high CPU utilization bug occuring whenever a terminal connection is lost, resulting in a SIGHUP which is ignored. (This is an example of a software author's temporary insanity. I mean, what sane programmer would set SIGHUP to SIG_IGN for a terminal-based program huh? Thought so :) Thanks to Dop Ganger for the symptom report. Refined Ethernet station monitor rate updates and scrolling code. Fixed autosave bug for non-TCP filters (this was working before 1.1.0. All of a sudden, the function call disappeared mysteriously. Must have been sleepy that time :) Fixed bug in UDP filter default settings. Added option to display TCP and UDP ports in either name form or numeric form (on a suggestion by Felix von Leitner and others). Added facility to describe Ethernet addresses for the Ethernet station monitor (to address needs as presented by Erlend Middtun via James Ullman ) Added an additional field to the TCP/UDP filter dialogs to allow the user to "exclude" certain addresses from the display allowing all others. Details on the new behavior are in the manual (on a suggestion by Sean Hough ) Relaxed screen management code to better adjust to the number of lines on the screen. As of this release, columns are still based on a maximum number of 80 though. Also under study is a SIGWINCH handler, but this will have to come later (on comments and suggestions by a *lot* of users...thanks guys :-) ). Fixed a subtle bug in the rvnamed interface IPC code, resulting in an accurate transfer of data but causing recvfrom() to return an EINVAL at unpredictable intervals. Bug was an uninitialized address structure length parameter. Code in both iptraf and rvnamed was fixed. Eliminated unsupported interfaces from interface selection lists. Included enforced restriction disallowng multiple instances of IPTraf and an overriding command-line parameter. (This may just be temporary, in lieu of a more elegant solution). Included autosave for TCP and UDP filters. Filters now survive IPTraf exits and restarts without requiring manual reapplication (on a suggestion by Chad Clark ). Included upgrade program and makefile rule to convert IPTraf 1.1.0 configuration and filter files to 1.2.0 format. Clarified TCP/UDP and non-TCP/UDP filter error messages. Color-coded the TCP and UDP protocol/port indicators in the TCP/UDP service monitor for better identification. Revised IP traffic monitor to query rvnamed only once per invocation of the facility. Less overhead. Revised IP traffic monitor to open and close the rvnamed communication socket only once per invocation of the facility. Less overhead. Added a 2-second delay after the rvnamed invocation to give the daemon more than enough time to open its sockets. Fixed SEGV condition which occurs when an attempt is made to destroy an interface list never loaded (which could only occur if the /proc system is unreadable, something which shouldn't happen on any decent Linux system). Moved filter list load routine to fltmgr.c, for better linking with the cfconv module. Makefile now installs rvnamed together with the iptraf executable in /usr/local/bin by default. Added table of contents (hyperlinked in the HTML version) to the manual. Cleaned up the Makefile. New features in IPTraf 1.1.0 and changes to IPTraf 1.0.3 Added command-line options for direct facility access from the shell, and an appropriate help screen for IPTraf invocation (on a suggestion by BJ Goodwin ). Added separate DNS reverse name lookup program (rvnamed) for quicker response time on reverse DNS lookups. Subsequently modified the revname function to use the new functionality. This also required additions of address resolution state fields to struct tcptableent in tcptable.h. Added checkrvnamed() and killrvnamed() to revname.c, used by itrafmon.c to query and stop the rvnamed daemon. Added scrolling capability to the general interface statistics. Interface list will now grow as packets from newly created interfaces are received (e.g. PPP interfaces). This now makes IPTraf better suited to monitor Linux machines configured as access servers. Interface selection lists can now be scrolled. Increased maximum number of entries in for the non-TCP window in the IP traffic monitor from 256 to 512. Fixed SEGV condition in itrafmon.c that happens whenever the Down cursor key is pressed with the lower window active, but not yet full. Added elapsed time indicators to each facility, showing the hours and minutes that have passed since the start of the monitor (on a suggestion by James Ullman ) Changed ncurses include file references from to Cleaned up preprocessor code for glibc2 support. Thanks for help and suggestions from John Labovitz . Thanks also for a test account on debs.fuller.edu opened by Christoph Lameter . Fixed SEGV condition which may occur when trying to close the log file which may never have opened (thanks to John Labovitz for the patch). Adjusted cosmetic code to better indicate the closed status in the TCP monitor. TCP and UDP filters now accept host names in in place of IP addresses. Host names will be resolved and can still be used with wildcard masks (may be useful for names that resolve to several IP addresses) Distribution now includes an HTML-formatted manual. Changes to IPTraf 1.0.2 Fixed SEGV condition when scrolling commands are applied to an empty Ethernet station monitor Distribution executable now comes compiled with -m486 by default. Binary will still execute on a 386, but a 486 or higher is still preferred. Changes to IPTraf 1.0.1 Fixed conflicting hotkey for non-TCP filter menu items RARP and IGRP (the "R" key). Changed the shortcut key for RARP to "P". Modified layer-2 header stripping code to cleanly ignore packets from unrecognized interfaces (see README). Fixed "duplicate port" misbehavior for the "Additional port" dialog's Cancel command Added error-checking for the port list file open sequence. Added PgUp/PgDn capability to the facilities that can be scrolled (IP traffic monitor, TCP/UDP services, and Ethernet station monitor). Cleaned up scrolling code a bit. Fixed bug in the non-TCP logging facility that caused extraneous log entries whenever the window is scrolled. Sent non-fancy messages to standard error rather than standard output. Changed a few messages Changes to IPTraf 1.0.0 Fixed X/Ctrl-X keystroke bug in the General Interface Statistics module (thanks to BJ Goodwin ). This was kinda an emergency, so I fixed this and released 1.0.1 immediately.
