Change Log
v1.4.3
o fix lack of -a and -l flags (short versions of --alarm and --log)
o merge FreeBSD ports upstream changes:
- distribute manpage uncompressed
- more strictly follow @prefix@ values: no hard coded paths
v1.4.2
o fix lack of compliling for many people from 1.4.0's time.h change:
we now use sys/time.h again, but this causes warnings for me with
glibc 2.2 (thanks Fredrik Steen and many others)
o fix two '-d' flags (thanks Fredrick Steen)
v1.4.1
o for whatever unknown reason sntop.h was not in the tarball. oddly enough,
i use a script to package sntop. hmmpf.
v1.4.0
o added daemon mode, via --daemon and -d. makes sntop capable of
running in the background.
o README file added to tarball
o fixed the warning-on-compile about time functions (in recent glibcs?)
by moving the include from sys/time.h to time.h, does this break anyone?
o moved -d to -e (--wfile)
o add --byte and -b option to set fping ICMP ECHO packet size
(patch by Fredrik Steen)
v1.3.3:
o fix dumb typo where sntop.c did not compile (Fredrik Steen)
v1.3.2:
o fping-alpha-deb does not like hardcoded packet size of 12,
so we now use 24 -- its no big deal. (thanks Frederick Steen)
o consolidated the various option flag variables into one using
binary flags -- decreasing memory footprint
o moved defines and funciton prototypes to a seperate header, sntop.h
o manpage fixes
v1.3.1:
o '--help' incorectly showed the '--once' flag as '--only'
o mixing '--once' and '--html' would create a html page
with a refresh time of 0 (thanks Bob Otterson)
o manpage correction (thanks hap)
o returned the header bar to pre-1.3.0 style
o fix for longopts structure
o we have confirmation that sntop works on Tru64 UNIX
(Bob Otterson)
o debs now available! (thanks Fredrik Steen)
v1.3.0:
o (finally!) added feature to execute command on site
connectivity change. see '-l' and '-a' flags
i wrote this 30,000ft in the air on a flight to philly.
See the manpage and the sample alarm.sh
o added color support - ncurses color will now be used to
display sntop in various colors, with UP sites in green
and DOWN sites in red. this MAY not work on older curses
implementations -- let us know. it is togglable via -c
or --nocolor (much thanks to Ron Cooper)
o the html automatic reload will now respect '-r' if given
o another e-mail fix
o some cosmetic changes (Ron Cooper)
o some little fixes and cleanups (it was a boring flight)
v1.2.1:
o fixed parse-error bug in Makefile (thanks Cristian)
o generated html will refresh automatically (thanks Adi)
o we now have are a FreeBSD port!
see http://www.freebsd.org/cgi/ports.cgi?query=sntop&stype=all
and ports/net/sntop
thank you Matthew Emerton
o some e-mail and name fixes
v1.2.0:
o new configure script! run './configure' prior to make
o greater portability added with new configure script
o GNU-style long options now accepted (see --help or 'man sntop')
o the generated html file now includes a timestamp (thanks Jeff Sofferin)
o get() and load_config() optimizations
v1.1.5
o we abort on failure to fork() or exec() now, so if (f)ping is
not found, we exit
o max file path size increased again, this time 128->256
o some minor improvements in the conf file processing routine
o some minor improvements in the get() reading routine
o small problem reading path (from environ) on some FreeBSD (and other?)
platforms (thanks, again, Matthew Emmerton)
o switched environ from a global to a local variable
o added TODO file
v1.1.4
o forget to mention '-p' flag in usage syntax or man page (thanks Matthew
Emmerton)
v1.1.3
o now works in FreeBSD (thanks Matthew Emmerton)
o compile against ncurses instead of curses
o file paths (to conf and html) have increased from 33 to 128 characters
(thanks Piotr Klaban)
o output format changed slightly (suggestions from Piotr Klaban, others)
o option '-p' will use stock ping instead of fping, but note that using ping
will be much slower than fping
o more Makefile changes
o changed default refresh interval to 180 seconds
v1.1.2
o now works in OpenBSD (1.1.2 tested on OpenBSD 2.6)
o Makefile now warns on exact directory error
o Makefile will not overwrite global /etc conf file if it exists
o (fixed) html display problem (thanks Frederic Tyndiuk)
v1.1.1
o renamed the project to sntop, we conflicted with the "other" ntop
o added flag '-s': secure mode - disable interactive keys for a nice "run on
any spare terminal" experience
v1.1.0:
o added flag '-o': poll and display results once, then exit
o interactive command 'q' will quit cleaner now, preserving all of the sntop
display
o manpage now included -- man sntop
o renamed config file from sntop.conf to sntoprc
o sntoprc is now read from ~/.sntoprc (or what -f forces) and then from a
system-wide config in /etc/sntoprc if that fails
v1.0.5
o get() optimizations
o added 'fomit-frame-pointer' to the default build statement
v1.0.4:
o added interactive command 'w' to toggle ON/OFF html generation
o inline comments now acceptable in the conf file
o trailing whitespace now ignored in the conf file
v1.0.3:
o added realtime interactive keyboard commands (r, q, etc)
o (fixed) hf = fopen(...) if kept within start_html was evil
o (fixed) reloading conf data would leak the last host record
o (fixed) although not manifested, there was a bug in the conf file buffer routine
v1.0.2:
o automatically generate an HTML file with the status
o catch SIGINT as to endwin() on CTRL-C
o argument flags (r, f, v, h, w, d)
o (fixed) if the conf file does not exist, the application locks
v1.0.1:
o optimize clear routine to clear only from third line down
o Makefile supporting compile, clean, and install
o replace system() with a custom fork/exec, glibc's disables interrupts
o use same-sized char arrays (otherwise implement intelligent strcpy's?)
o strcpy(dest,src) -> strncpy(dest, src, 33) to protect buffer
o implement actual fping
o replace the hard coded loops using the conf file
o use a sntop.conf located in /etc for host information
v1.0
o initial stable release
