RB wrote:
 I've had a request to increase logging duration on systems that have
 no access to an external syslog server, so am making the necessary
 changes to maintain much larger ring-log files.  Incredibly larger -

what we've done is to make a few tweaks and install syslog-ng

1/ change the system include file so that it starts syslog with -b
127.0.0.1 so that it doesn't bind to an external IP.

2/ add some lines to /etc/rc.conf.local to make a restart of syslog also
bind only to localhost:
syslogd_enable=YES
syslogd_flags= -s -f /var/etc/syslog.conf -b 127.0.0.1

3/ install syslog-ng and write config so that it does full logging to
local file system as well as copying to a main log server

3a/ pkg_add -r syslog-ng
3b/ config file is /usr/local/etc/syslog-ng/syslog-ng.conf
(if interested, I can provide ours after sanitisation)
3c/ make syslog-ng listen on, say, the sync interface or lan.

4/ add some lines to /etc/rc.conf.local to make sure that syslog-ng
starts up

5/ use the pfsense gui to tell it to log to the syslog-ng IP address

this works for us, and the key thing is that apart from having to fix
the /etc/inc/system.inc file when upgrading pfsense (I offered the
diffs/patch, I think it might have been accepted), you don't have to
bend the system too far as you don't have to hack any other part of pfsense.

[pfSense-discussion] freebsd 6.2 ports archive

2008-03-13 Thread Paul M
Hi,
I was looking for the syslog-ng package to install on my pfsense boxes,
and discovered that the main freebsd site no longer has the ports for
that release - only 6.3.

I found the ftp.de.freebsd.org site still had it, so I did an evil hack
to the hosts file thus:
213.83.42.56ftp.freebsd.org

and I was able to pkg_add -r syslog-ng.

anyway, my point is that anyone wanting to play with pfsense1.2 release
and needs access to the ports might want to consider maintaining their
own archive of the freebsd downloads otherwise they'll lose out!

or, perhaps, should pfsense.org website keep a mirror for this purpose?

 We are working on it: http://blog.pfsense.org/?p=179

freebsd is nice in that the paths to the files are the same on each
mirror, so hacking the hosts file made it work with no changes; the
equivalent path was this:

[pfSense-discussion] internal load balancer doesn't return traffic to originator

2008-02-11 Thread Paul M

scenario: two machines, on (A) 10.x.x.11 and (B) 10.x.x.12 run web
servers on port 1024 which are made available to the world via public IP
on port 80 by a pfsense firewall (F) (1.2RC4) running a load balancer.
the internal IP of the firewall is 10.x.x.254.

an application which runs on the 10.x.x.11,12 and others wishes to
connect to the web server pool.

nat reflection doesn't work, so we thought we could run a load balancer
on the firewall's internal IP address. however, this doesn't work.

using tcpdump on A, we see the firewall connecting to the web and the
packets being returned normally, everything OK.

using tcpdump on F, we can see the packets arrive on the firewall
heading for10.x.x.254:80, and go off to the web server on port 1024,
and come back to the firewall. the firewall doesn't then send the
packets back to the host which originated the connection.

firewall logs indicate the connection is being permitted from A to A, no
indication of anything being refused!


is what we are trying to do sensible, i.e. to use a load balancer on the
*inside* of our network to allow callbacks to a webapp to be made resilient?

thanks

 That could cause you problems potentially.  But would be no different

we've got seven boxes doing pfsense - three pairs of 1U servers as
firewall clusters protecting public facing web services, and one acting
as a VPN concentrator for road warriors. we rely on carp and the load
balancer to give resilience.

when one machine threw a disk, it took less than half an hour to
restore functionality.

all are 1.2RC3, some began as 1.2rc2.

we considered Astaro during early eval, but it would have been expensive
to have so many boxes, so we'd have had to compromise on the design of
our network, pfsense has thus made it possible to adopt a much more
flexible solution.

I think that proper ssd units designed to replace a regular magnetic
hard drive have to have very sophisticated wear-levelling algorithms,
and probably have an intermediate store for written data, e.g. some
battery-backed SRAM or non-wearable memory.


By ensuring you mount the drive noatime and async
 you can reduce the number or writes; mounting everything except
/var/log as read-only would enforce no writing. Perhaps put /var/log
into a ram disk, rotate logs frequently and rsync them to flash would
help too. However, this is speculation on my part as I've never created
my own unix/linux flash based system (although I do have a zaurus, but
rely on the distro creaters to solve the problem!).

BTW I've seen very few reports of people having problems with the
microdrive in their zauruses which take the 4 or 6GB drives, but people
