Thanks go out to the following people who have helped me debug and extend sac to the pinnacle of perfection that it is. =)

• Found bug in the way sac releases logins when EOF is reached that made clipping not perform correctly (only for logins currently active).
• Suggested extending -s and -e options to allow for more precision than just days. Thus: mm/dd/yy [hh:mm[:ss]] (implemented as -M [hourrange] for the time being).

• Provided tacacs wtmp to implement -t (now -X[3|4]) option to support tacacs special wtmp format.

• Suggested the -b option.

• Suggested -o option to support tacacs old wtmp format. Provided wtmp for testing.

• Added functionality to the Makefile and FSSTND compliance.

• Got me to implement clipping finally.
• Suggested --help option.
• Made C code comments reflect reality.
• Suggested -x option.

• Suggested allowing wildcards for -T option.

• Contributed patmatch() code for wildcarding.

• Helped diagnose and provided wtmp files to fix daylight savings time problem. Also bugged the hell out of me. =)

• Helped diagnose and provided wtmp files to fix daylight savings time problem. Also bugged the hell out of me. =)
• Provided Cistron Radius radwtmp and detail for testing. Necessitated -C option.

• Provided radius detail file and other files for helping implement radius support.

• Provided tacacs 4.x wtmp for sac to support (via -X4) it's new utmp format.
• Pointed out problem with -t option.

• Pointed out problems with -t option when used with -s and/or -e.
• Suggested --version option.
• Suggested gnuplot graphs for usage. (looking into it).

• Showed me how screwed up my radius processing was.
• Suggested allowing more than one wtmp on the command line (make -w option list oriented).

• Discovered bug with -w where cleanup() was not called after each wtmp.
• Detected problem in radius processing where the last radius entry would be lost due to end of file detection.
• Detected problem in output of the report when compiled with older libs and/or compilers.
• Ran tests that suggest using fclose() in doitradius() and possibly unbuffering radius input reduces memory usage in sac.

• Suggested stripping leading !'s from usernames in radius detail files.
• Suggested removing @hostname from usernames in radius detail files.
• Inspired -D option.

• Suggested to format time in H:M:S instead of fractions of hours. --hms, --hm, --hours, --round.

• Suggested the -i option and provided wtmp for testing.

• Suggested radius processing wouldn't be complete if it didn't account for stop records with no start records at the beginning of a log.

• Provided detail log entries for testing with yet another version of radius.
• Suggested Makefile define for name of "detail" file for with other languages.
• Suggested the -l option.

• provided information on changes necessary to make sac compile under glibc 2.0.

• Suggested that sac give up processing a log and just report what it has if it hits a time warp instead of trying to go ahead and deal with a bad log, which consumes major memory and CPU time.

• Contributed fixterm.c source, to fix xterm logouts in wtmp file.

• Suggested @ includes for -u, -x, -T and -H options.
• Suggested -R to easily select multiple radius logs.
• Pointed out that -x should remove users specified by -u option from accounting.

• Pointed out problem with clipping causing segmentation fault and provided wtmp for testing.

• Provided radwtmp to debug Cistron radius support.
• Discovered bug in rawtmp w/ reguard to radwtmp files.
• Suggested I tell people where to get sac in my README and INSTALL files.
• Suggested minor sub-version numbers. ARGH!

• Spotted error with -l when logins wrapped past midnight.

• Discovered problem with min/max output when processing more than one log at a time. Provided radius logs for testing.
• Suggested -m work with -p.
• Suggested -l option be able to show Framed-IP-Address as the "hostname" for radius logs instead of NAS-IP-Address.

• Discovered problem in tty reporting where # logins reported with -a option was incorrect.
• Suggest removal of punctuation from output.
• Suggested simultaneous tty usage option (-U) and helped debug the -U option.

• Discovered bug in radius detail processing where a null username would crash sac. Null usernames are now reported with the username of "UNKNOWN".

• Requsted option to ignore specific amount of time before beginning accounting (-I option). Useful for this kind of accounting:

  First X hours: free, charge after X hours of usage:

  Time slots A: Tk a/min B: Tk b/min C: Tk c/min

• Provided new sac.cgi and sac.html files as example scripts. Works with RADIUS but can be easily modified to work with wtmp.

• Discovered that shutdowns with a line of ~~ where not being considered.
• Suggested the --cutoff and --discard options.

• Discovered problem with packet accounting and per user reporting.

Plus others who might have gotten lost in the heap of mail I get from all the mailing lists I subscribe to. Mostly these people just complain, so who cares eh? =)
