Now I have to analyze the traffic with ntop to have statistical information to debug a connection. As ntop can process pcap capture files I've done this trick: Working directory /home I created a fifo called dump.fifo (read permission by common user) then this one line script that cat dumpfiles through fifo (filenames are chronologically ordered): for i in $(ls -tr1 dump08*); do echo $i; cat $i > dump.fifo; done in another terminal I execed the ntop program: ntop -P /tmp/ntop -f /home/dump.fifo -m 10.1.102.0/24 -s -w 3001 -W 0 ntop runs in foreground and complaint about rrd files: lun 22 set 2008 13:28:21 CEST **WARNING** RRD: rrd_update(/tmp/ntop/interfaces//home/dump.fifo/throughput.rrd) error: opening '/tmp/ntop/interfaces//home/dump.fifo/throughput.rrd': No such file or directory lun 22 set 2008 13:28:31 CEST **WARNING** RRD: rrd_create(/tmp/ntop/interfaces//home/dump.fifo/throughput.rrd) error: Invalid alpha: must be between 0 and 1 lun 22 set 2008 13:28:31 CEST **WARNING** RRD: rrd_update(/tmp/ntop/interfaces//home/dump.fifo/throughput.rrd) error: opening '/tmp/ntop/interfaces//home/dump.fifo/throughput.rrd': No such file or directory I've found that this problem is very common but I didn't find any solution..... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
