Hello! I've been using NTOP for a while, but can't get it to save the stats correctly. When using -S 1, often a seg fault will occur - I can't seem to see any pattern behind it - it's been running for two weeks once, but afterwards it was about 30 seconds. I've recently updated to the latest CVS (17 Sept), but now can't get it to run for more than 10 minutes. I've noticed that just before a crash, the hosts list fills up with MAC addresses that are flagged as gateways??! The second issue is that it keeps flagging specific hosts as having duplicated MAC addresses, but I can't see where the duplicates are. If it is being truthful, please can we have some idea of where the duplicate is? The system is SUSE 7.1, with GBDM 1.8.0, and libpcap 0.4 (is this right?) Below are two dumps - the first with -i eth0 -w 3000 -P /var/lib/ntop -S 1 The second is the same, but with -t 5 on the end. This crashed before I could access the system! ----1 Wait please: ntop is coming up... 19/Sep/2001:03:11:50 Initializing IP services... 19/Sep/2001:03:11:50 Initializing GDBM... 19/Sep/2001:03:11:51 Initializing network devices... 19/Sep/2001:03:11:51 ntop v.2.0.0 MT [i686-pc-linux] (09/17/01 04:06:06 PM build) 19/Sep/2001:03:11:51 Listening on [eth0] 19/Sep/2001:03:11:51 Copyright 1998-2001 by Luca Deri <[EMAIL PROTECTED]> 19/Sep/2001:03:11:51 Get the freshest ntop from http://www.ntop.org/ 19/Sep/2001:03:11:51 Initialising... 19/Sep/2001:03:11:51 Truncated network size to 1024 hosts (real netmask 255.255.248.0) 19/Sep/2001:03:11:51 Loading plugins (if any)... 19/Sep/2001:03:11:51 Searching plugins in /usr/lib/ntop/plugins 19/Sep/2001:03:11:51 WARNING: unable to load plugin '/usr/lib/ntop/plugins/arpPlugin.so' [undefined symbol: sendHTTPHeaderType] 19/Sep/2001:03:11:51 Welcome to icmpWatchPlugin.
