Re: Remote Fping Problems...

We had this problem before. Thanks to Keith Patton, he provided a patch
for and it started working.
I thought that the patch should have been included in the latest
SmokePing distribution but I might be wrong.
Attached is the patch.

I'm just a bit lost now ;-)

I followed the instructions for configuring ssh and rsh to do an fping
If i give the command "ssh someuser <at> someip fping somehost" this works,
so i
should be allowed to use a probe for remote fping.

[PATCH] bug fix for filter feature in 1.24

The new filter feature in 1.24 is really useful for consolidating RRDs from various
sources but also to separate probes on a single box into different process so a timeout
doesnt affect all the probes.

There is 2 bugs in 1.24 that needs attention.

The first one is proper GetOpt handling for the new --filter argument (maybe my version of GetOpt is picky)

The second one is that even if you specify a filter, smokeping will still update *all* the RRDs regardless if
they match the filter or not in update_rrds.

Yes it does only the measures for the filtered ones but all RRDs are updated which cause packet lost to
mysteriously appears in FPing RRDs when another smokeping process just updating Curl RRDs write null
values to FPing RRDs as well.

Patch is below, hope it helps others.

Hi Francois,

Congratulations, you seem to be the first person to use the filter

Short description says:

   -t n       individual target initial timeout (in millisec) (default

That is the timeout for the first packet. Not for all following. E.g.

fping -c 3 -t 50 : [0], 84 bytes, 151 ms (151 avg, 0% loss) : [1], 84 bytes, 149 ms (150 avg, 0% loss) : xmt/rcv/%loss = 3/2/33%, min/avg/max = 149/150/151

I.e. the first packet is mising. This will be clear when you do:

fping -c 3 : [0], 84 bytes, 149 ms (149 avg, 0% loss) : [1], 84 bytes, 152 ms (150 avg, 0% loss) : [2], 84 bytes, 148 ms (150 avg, 0% loss) : xmt/rcv/%loss = 3/3/0%, min/avg/max = 148/150/152

Re: Ecartis command results: subscribe

Hello All,

First of all, I am a recent convert to MRTG and to smokeping. Very nice 

I had quite a bit of trouble getting smokeping to work. I noticed on 
the mailing list archives that a lot of other people also had the same 
problem, so I thought I would share my experience:

After installing smokeping and trying to access it via:

I would get the following Server error:

The server encountered an internal error and was unable to complete 
your request.
Error message:
Premature end of script headers: smokeping.cgi
If you think this is a server error, please contact the webmaster

Error 500

The scripts runs fine from a shell. The html generated views fine in a 
browser. So I spent much time reading source and also looking at 
Apache's config file. Everything seemed correct.

Finally, I cam across an email from someone on the apache mailing list 
that suggested that there may be a file permissions problem and to 
check out the suexec.log (in /etc/httpd/logs/suexec.log). Sure enough:

IOSPing problem


I just found that SmokePing simpy doesn't start IOSPing probes at all, I 
added debug output to and
this is what I see.

vader:/usr/local/smokeping/bin # ./smokeping --debug
### assuming you are using an IOS reporting in miliseconds
Launched successfully
IOSPing: probing 9 targets
Running probes
IOSPing: forks 5, rounds 2, timeout 150

It doesn't appear.

Any ideas?

Instalation problem - maybe perl

I tried to install smokeping. I isntalled, but after I have installed all

Re: Instalation problem - maybe perl


thanks a lot for the infos you taught me. They were very useful. It seems 
now that smokeping started working. It has already created the directory 
with the .rrds , then it seems to be working.
But now I am going to ask for your help for another problem. Despite it runs 
storing the infos in the .rrds, I can't see them because there are some 
errors like:
1) The smokeping.cgi (actually pxt.cgi) file wasn't at the 
/usr/local/apache/cgi-bin directory when I started smokeping. I had to put 
it manually (I don't know if it is the correct way)
2) After I had put the smokeping.cgi in the cgi-bin directory, the template 
of Smokeping started working, but it doesn't show the graphics. It accuses 
some problems like:
- ERROR: Opening '/usr/local/apache/pid/pxt/BRA/router1a_mini.png' for 
write: Permission denied
- ERROR: Opening '/usr/local/apache/pid/pxt/BRA/router1b_mini.png' for 
write: Permission denied
- ERROR: creating  /usr/local/apache/pid/pxt/BRA/router1a: No such file or 
- ERROR: creating  /usr/local/apache/pid/pxt/BRA/router1b: No such file or 

Here is a copy of my config file and my smokeping.cgi (acctualy pxt.cgi) 
file. Idon't know if they might help, but...
