Nevím si rady s modulem ping. Všechny ostatní moduly běží bez problému, ale ping nevytváří obrázky. Proces pingu běží, ale skript pro vytváření nic neudělá.

Mám naistalováno: Linux version 2.6.18-1.2257.fc5 (brewbuilder@hs20-bc1-5.build.redhat.com) (gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)) #1 Fri Dec 15 16:04:33 EST 2006

Hotsanic 0.5.0-pre5

"Chyba" při spuštění skriptu diagrams.pl:

creating images for 10.33.10.67 ( AP Bratrk) ... 
Use of uninitialized value in printf at ./diagrams.pl line 167 (#1) 
(W uninitialized) An undefined value was used as if it were already 
defined. It was interpreted as a "" or a 0, but maybe it was a mistake. 
To suppress this warning assign a defined value to your variables. 

To help you figure out what was undefined, perl tells you what operation 
you used the undefined value in. Note, however, that perl optimizes your 
program and the operation displayed in the warning may not necessarily 
appear literally in your program. For example, "that $foo" is 
usually optimized into "that " . $foo, and the warning will refer to 
the concatenation (.) operator, even though there is no . in your 
program.

Ještě uvádím výpis konfiguračního skriptu modulu ping:

# set type of diagrams (whatever you like best ... Thanx M. Renner! ) 
# classic (default) -> shade ranges for min, avg, max in different colors 
# simple -> only shade area between min and max in light blue 
#

# set diagram scaling 
# log -> set logarithmic scaling (default) 
# lin -> set linear scaling 
# 
SCALE="lin" 

# set diagram initial upper border in milliseconds (for better graph comparison) 
# UPPER="10" sets all diagrams upper border to 10ms 
# UPPER="0.01" sets all diagrams upper border to 100us 
# 
UPPER="1" 

# how many ping processes shall be done in parallel. Reducing the number 
# causes the process to run longer, but keeps your system load a bit lower. 
# 
PARALLEL="4" 

# use system's "ping" command instead of perl library. This is useful when not 
# running as root. Fallback is implemented in case Net:ing is not installed 
# on your system 
# 
# SYSPING="0" use Net:ing library (default) 
# SYSPING="1" use system command 
# 
SYSPING="0" 

# If SYSPING is set to "0", then you may specify the protocol used to ping all 
# hosts. Valid are "icmp" (the default) and "tcp". If you run HotSaNIC without 
# root privileges, you should use "tcp" - but note, that some hosts don't reply 
# to tcp ping packages!
