[mrtg] Problem with mrtg-rrd

[Tim Wagner]

Hello,

i'm using mrtg 2.16.2 with mrtg-rrd 0.7 (normal debian/lenny 
repository). for the web presentation i use lighttpd but i tried apache 
an got the same errror.
mrtg works without doubt and gather all the values of the configured 
switches and routers and create/update the rrd files well.

if i open http://<serverip>/cgi-bin/mrtg-rrd.cgi the site open an i can 
choose a device (i use the parameter "--subdirs=HOSTNAME") that will 
open http://<serverip>/cgi-bin/mrtg-rrd.cgi/<routerip>/ and i can see a 
site with all my configured interfaces and their graphs. everything 
works well until now.

but if i choose an interface now (it open for example the url 
http://<serverip>/cgi-bin/mrtg-rrd.cgi/<routerip>/<routerip>_se2_1.html) 
it open a site with all the normal information (System, Maintainer, 
iftype, etc.) as well as the bandwidth information in textual and the 
graphs for weekly and monthly but not for daily and yearly (yearly is 
clear because the mrtg just run for 4 hours).

if i now refresh the page (press f5 or something else) no graph is 
shown. just the textual information what means that the rrd files are 
accessible.

after that i can open the url abitrary often with no affect, the graphs 
are not shown.

i took the url from the html source code and enter the graph directly, 
and i can see a wonderful graph.

and now the question, what is creepy with my installation? :-)

i used several browsers (firefox 3.0.12, ie6, ie7, epiphany 2.26.1) and 
several web servers lighttpd and apache. the behavior is in every 
combination identical.


best regards,

tim
