Hey all, I
am actually experiencing a few problems with ntop. Everything installs fine and
runs, but after a short while, everything freezes, ntop’s cpu usage drops
to between 0% and 9%, the memory usage is at 66% and I every time I try to load
any of the website pages, it just hangs. I had tried ntop in the past (v2.2)
and it didn’t work out for me. CPU usage was outrageous and would bog
down the machine. I like how this new version handles but I can’t have it
freezing on me all the time. I’m
running this on a P4 2.8 with 512mb memory. I’m using RedHat 9 with the
Linux 2.4.20-31.9 kernel. All of the prerequisites for ntop (libtool, libpng,
gd, gdbm, etc.) have been installed with the most recent versions available for
release. I’ve tried both release and development versions of the latest
ntop and run into the same problem each time. Now
for my other problem. When it IS running, I can’t get the local subnet option
(-m) to work at all. I have a rather EXTENSIVE list of subnets that I’d
rather not mention here for security purposes. I work for an ISP with about
5000 subscribers being pushed through this machine. Basically, what happens is
that I click on “Local Only” on the website, and it shows no
information. Or sometimes it will show one or two IPs but then they disappear
on the next refresh. I’ve tried it with only one of the subnets and that
doesn’t work either. I can see the IP addresses reporting they are Remote
instead of Local. At one point, I loaded with the –m option and got this
error: Thu Feb 24 18:01:02 2005 **ERROR** Buffer too short @
rrdPlugin.c:2358 (increase to at least 805) Thu Feb 24 18:01:02 2005 **WARNING** RRD: Net mask
'255.2' not valid - ignoring entry I have been unable to duplicate this error. It seems like it
is cutting off my list at a certain point. If this is the case, this won’t
work for me. I need each of these subnets in there. And, yes, the format is
correct. Does anyone have any suggestions for me? I feel like I’ve tried
everything including removing everything I installed and starting fresh. It
still comes back with the same problems. Any help would be greatly appreciated.
Thanks. Adam |
