|
||
|
|
- Revision v2.4b2-to-IPv6
|
||
|
|
- Added IPv6 support.
|
||
|
|
- Added -I option for selecting source IPv4/IPv6 address.
|
||
|
|
- Makefile.in now generates a Makefile which will build both
|
||
|
|
fping (IPv4) and fping6 (IPv6). Thus it makes an fping (IPv4 only)
|
||
|
|
and an fping6 (IPv6 only).
|
||
|
|
- num_unreachable was counted twice when a sendto() generated errors.
|
||
|
|

|
|
- Revision v2.4b1
|
||
|
|
- added -g option for generating IPs from a start to an end value
|
||
|
|
- two available options, generate IPs from start IP to end IP
|
||
|
|
or from a passed netmask, such as 192.168.1.0/24

Jason Ewasiuk <jasone@remote.net>
|
||
|
|
- Revision v2.3b1
|
||
|
|
- formatting changes to code layout (fping.c)
|
||
|
|
NOTE: Best viewed with a tab stop of 4
|
||
|
|
- merged in changes from Debian c/o Herbert Xu
|
||
|
|
<herbert@gondor.apana.org.au>
|
||
|
|
- Compilation fix on alphas with glibc
|
||
|
|
- Alignment issues (note from JE: in wait_for_reply())
|
||
|
|
- A typo with the time specified on the command line
|
||
|
|
(note from JE: bug was using 10 instead of 100)
|
||
|
|
- Drop privileges after obtaining socket
|
||
|
|
(note from JE: might be moot, since prog exits if
|
||
|
|
user is not root)
|
||
|
|
- touched all files in package to this date
|
||
|
|
- couple new #ifdefs added for future WIN32 support
|
||
|
|
(Haven't got to adding this yet, will take a lot of rewriting.)

Wed Jan 8 11:18:37 1997 Roland Schemers <schemers@stanford.edu>
|
||
|
|
|
||
|
|
* Created ChangeLog file. What follows was from the CHANGES file.
|
||
|
|
|
||
|
|
* Revision 2.0 1994/10/31 21:26:23 morgan
|
||
|
|
|
||
|
|
Substantial rewrite, including new features:
|
||
|
|
|
||
|
|
support some traditional ping features:
|
||
|
|
loop mode
|
||
|
|
specify size of data packets
|
||
|
|
specify how many pings to send
|
||
|
|
show per-response data
|
||
|
|
interpret ICMPs other than ICMP Echo response
|
||
|
|
|
||
|
|
also
|
||
|
|
|
||
|
|
rewrote main loop completely
|
||
|
|
make timings in tenths of milliseconds
|
||
|
|
do exponential backoff on retries
|
||
|
|
port to more systems
|
||
|
|
add some debugging stuff
|
||
|
|
do better checking on whether received ICMP is for us
|
||
|
|
|
||
|
|
* Revision 1.24 1993/12/10 23:11:39 schemers
|
||
|
|
|
||
|
|
commented out seteuid(getuid()) since it isn't needed
|
||
|
|
|
||
|
|
* Revision 1.23 1993/12/10 18:33:41 schemers
|
||
|
|
|
||
|
|
Took out the -f option for non-root users. This can be enabled by
|
||
|
|
defining ENABLE_F_OPTION before compiling. There is a call to
|
||
|
|
access before opening the file, but there is a race condition.
|
||
|
|
Reading from stdin is much safer.
|
||
|
|
|
||
|
|
|
||
|
|
* Revision 1.22 1993/11/16 19:49:24 schemers
|
||
|
|
|
||
|
|
Took out setuid(getuid()) and used access() system call to
|
||
|
|
check for access to the file specified with "-f".
|
||
|
|
|
||
|
|
* Revision 1.21 1993/07/20 18:08:19 schemers
|
||
|
|
|
||
|
|
commented out the test to make sure the ping packet came from the
|
||
|
|
same IP address as the one we sent to. This could cause problems on
|
||
|
|
multi-homed hosts.
|
||
|
|
|
||
|
|
* Revision 1.20 1993/02/23 00:16:38 schemers
|
||
|
|
|
||
|
|
fixed syntax error (should have compiled before checking in...)
|
||
|
|
|
||
|
|
* Revision 1.19 1993/02/23 00:15:15 schemers
|
||
|
|
|
||
|
|
turned off printing of "is alive" when -a is specified.
|
||
|
|
|
||
|
|
* Revision 1.18 1992/07/28 15:16:44 schemers
|
||
|
|
|
||
|
|
added a fflush(stdout) call before the summary is sent to stderr, so
|
||
|
|
everything shows up in the right order.
|
||
|
|
|
||
|
|
* Revision 1.17 1992/07/23 03:29:42 schemers
|
||
|
|
* Revision 1.16 1992/07/22 19:24:37 schemers
|
||
|
|
|
||
|
|
Fixed declaration of timeval_diff. Didn't notice the problem because
|
||
|
|
I use 'cc' in stead of gcc under Ultrix. Time to switch? :-)
|
||
|
|
|
||
|
|
Modified file reaing so it would skip blank lines or lines starting
|
||
|
|
with a '#'. Now you can do something like:
|
||
|
|
|
||
|
|
fping -ad < /etc/hosts
|
||
|
|
|
||
|
|
* Revision 1.15 1992/07/21 17:07:18 schemers
|
||
|
|
|
||
|
|
Put in sanity checks so only root can specify "dangerous" options.
|
||
|
|
Changed usage to show switchs in alphabetical order.
|
||
|
|
* Revision 1.14 1992/07/21 16:40:52 schemers
|
||
|
|
* Revision 1.13 1992/07/17 21:02:17 schemers
|
||
|
|
|
||
|
|
Changed the default timeout to 2500 msec, and retry to 3. This was
|
||
|
|
due to suggestions from people with slow (WAN) networks. The default
|
||
|
|
1 sec timeout was too fast.
|
||
|
|
|
||
|
|
|
||
|
|
Added '-e' option for showing elapsed (round-trip) times on pakets, and
|
||
|
|
modified the -s option to include min, max, and average round-trip times,
|
||
|
|
and over all elapsed time.
|
||
|
|
|
||
|
|
Modified action taken when a error is returned from sendto. The action
|
||
|
|
taken now considers the host unreachable and prints the hostname
|
||
|
|
followed by the errno message. The program will not exit and will continue
|
||
|
|
to try other hosts.
|
||
|
|
|
||
|
|
* Revision 1.12 1992/07/17 16:38:54 schemers
|
||
|
|
* Revision 1.11 1992/07/17 16:28:38 schemers
|
||
|
|
|
||
|
|
move socket create call so I could do a setuid(getuid()) before the
|
||
|
|
fopen call is made. Once the socket is created root privs aren't needed
|
||
|
|
to send stuff out on it.
|
||
|
|
|
||
|
|
moved num_timeout counter. It really was for debug purposes and didn't
|
||
|
|
make sense to the general public :-) Now it is the number of timeouts
|
||
|
|
(pings that didn't get received with the time limit).
|
||
|
|
|
||
|
|
|
||
|
|
* Revision 1.10 1992/07/16 16:24:38 schemers
|
||
|
|
* Revision 1.9 1992/07/16 16:00:04 schemers
|
||
|
|
* Revision 1.8 1992/07/16 05:44:41 schemers
|
||
|
|
|
||
|
|
Added _NO_PROTO stuff for older compilers, and _POSIX_SOURCE
|
||
|
|
for unistd.h, and _POSIX_SOURCE for stdlib.h. Also added
|
||
|
|
check for __cplusplus.
|
||
|
|
|
||
|
|
Now compiles ok under Ultrix 3.1, and Sun4 using cc. Also compiled
|
||
|
|
ok using g++ 2.2.2.
|
||
|
|
|
||
|
|
Changed '-a' and '-u' flags to be mutually exclusive (makes sense, since
|
||
|
|
specifiying both '-a' and '-u' is the same as not specifiying anything.
|
||
|
|
Since '-a' and '-u' are mutually exclusive, these options now only print
|
||
|
|
the hostname, and not the 'is alive' or 'is unreachable' messages.
|
||
|
|
This makes it much easier to do stuff like:
|
||
|
|
|
||
|
|
#!/usr/local/bin/perl
|
||
|
|
$hosts_to_backup=`cat /etc/hosts.backup|fping -a`;
|
||
|
|
|
||
|
|
Since you don't have to strip off the 'is alive' messages.
|
||
|
|
|
||
|
|
Changed usage to and stats to print to stderr instead of stdout.
