Re: [SLUG] script to analyse syslog in realtime
If you want something light for ad-hoc checks I use a bit of perl like this that uses a dumb match of part of the date-time string as a key into a hash of counts: #!/usr/bin/perl # # use strict; use warnings; my %events_per_minute; while() { chomp; if (m,to svrdmz:NTP/123 \(NTP/123\),) { $events_per_minute{substr $_, 0, 12}++; } } my $key; foreach $key (keys %events_per_minute) { print minute: $key count: $events_per_minute{$key}\n; } Of course you can improve this e.g. pass the event to match as an arg. Pipe to the usual sort -rn | head to get the top minutes by number of events. Preceded it with the tool since to only apply to events since the last time you checked. For fancier setups, use the tools mentioned by others or the venerable swatch Regards, Matt On Thu, Feb 14, 2013 at 11:48 AM, Chris Barnes chris.p.bar...@gmail.comwrote: Hi everyone, my firewall logs everything to a syslog server - new connections, terminated connections, etc basically what im trying to do is analyse the syslog in realtime looking for a specific string which indicates a new connection has been established, and to count the number of occurrences of that string to get an idea of how many connections per minute im getting for a particular internet service so that I can graph it.

These are entirely as is but free -- if they don't work you get to keep them anyway. :-) They did work last time they were turned on, which is about 7 years ago in the case of the Indy and 5 years in the case of the Sun machines.

Popular offenders are prelinking and manpage indexing but there are many other possibilities. Turn them off or move them to say 10am in the morning when no one is around. You can also try out powertop (from intel) which is intended to find things that use a lot of power. Those things also of course tend to make the cpu run hotter and start up the fans as well.

Is there another economical (and sane, speed-wise) way to get lots of disks on these system's bus? Thanks, How sane does the speed have to be exactly? :-) If the answer is not completely insanse then you could add a lot of esata/usb disks externally. If you run out of sata or usb, add more via pci cards. You might not get sata speeds as you might saturate the pci bus well before hitting the sata limit. If you want a little more speed (well, lower latency perhaps) at the cost of reliability you could raid0 them.

Fail = clicking noises, won't mount or mounts then won't read/write, etc. Whilst not an answer to your question, if you're fairly sure the drive is terminal it might be time to try a bit of percussive maintenance. I remember having similar problems with a drive many years ago and a sharp smack off the side of the desk did actually fix it. Whether the drive heads were stuck or what I don't know, but it was supremely satisfying nonetheless... File that under the Please don't try this at home category ;-) Craig FWIW, before you try percussive maintenance, I've had the clicking thing and sometimes it has been due to dodgy usb cable or cable insertion and once even rebooting linux fixed it - the usb driver had got into a funny state and was erroring no every connect. Rebooting fixed it. Matt -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Oracle 9i database and samba

I work for an ASP that has all of its Oracle databases (hundreds of them) mounted via NFS. It works just fine. The database servers are running Red Hat Enterprise Linux 4 and 5, and the NFS mount points are NetApp filers. I believe NetApps are specifically supported by Oracle but not NFS generally. (which you touch on later in this message) Even so this is just a convenience, it does nothing to 'share' the database unless you mean clustering. Access to the database is always by an Oracle protocol e.g. bequeath, sqlnet or something like jdbc, never by direct access to the files.
