Not really apropos of this list, but does anyone know where one can still
get a new laptop with Windows XP pre-installed as opposed to Vista? It's for
someone at work who's asking.
Thanks,

I asked about this at the meeting last week, but nobody present was
familiar with ipfilter, so I thought I'd ask here in hopes of finding a
Solaris and/or Mac guru familiar with firewall configuration on these
platforms...
I've been using the Linux kernel's Netfilter/iptables configuration for
some time now, to handle firewalling for each of our Internet-connected
Linux hosts, and I'd like to do the same for our Solaris and Mac OS X
hosts as well. I've found some reasonable tutorials …
[View More]and FAQ's online to
help with the basic setup, but I'm stuck with a few issues surrounding
connection tracking.
With iptables, you can load kernel modules to do connection tracking
that is application-layer-specific. I use 3 such modules:
- ip_conntrack_amanda, to handle Amanda backup requests
- ip_conntrack_ftp, to support FTP server data connections
- ip_conntrack_netbios_ns, to support NetBIOS name services
(e.g. in Samba)
I haven't found an equivalent mechanism in either ipfilter or ipfw to
allow for this, and their state-table mechanisms aren't powerful enough.
For example, for NetBIOS name services, the request goes out as a
broadcast, but replies come back directly, so they don't match the state
of the requests. (I can work around this by allowing all NMB replies
from the local net, but this is uglier.)
Amanda backup support is even trickier, for two reasons: First of all,
replies to requests can come back much later, after the state table
entries will have expired (whereas with ip_conntrack_amanda, you can set
a longer delay if needed), and secondly, there will be related,
follow-up connections on other ports, which need to be tracked. (Again,
I can work around this by allowing replies from the amanda port for
hosts on the local net, using a separate rule, as well as opening up
entire ranges of other ports for the local net. Again, this is uglier.)
Supporting an FTP server is even more problematic, particularly if I
want to open it up to connections from outside of the local net, without
opening up an entire port range to the outside world as well.
Any suggestions for clean, secure ways to implement firewall support for
these services using ipfilter or ipfw?

I'm looking for two (unrelated) things right now:
1) an older laptop I could borrow, P-III 1GHz or better, 256Mb RAM or
better, 4Gb HDD or better, **with a PS/2-style keyboard/mouse port**. I
only need one for (I think) about 3 months, so I don't want to go buy a
laptop for this particular purpose. Renting such a thing could be for a
token amount only.
2) a CMS specialist for hire. Drupal, Plone, Joomla, don't care... but
looking for any consultants who are actually comfortable with any of …
[View More]these
systems *today*. I can get myself up to speed fast enough, otherwise. If
you know of anyone, please let me know.
Thanks,

I now know of two people who have paid to download Open Office. There is a
company that that pops up in google searchs and looks official. It charges
$29.88 to download OpenOffice. The name that appears on your credit card
statement is mbcontact.com.
A google search indicates that many people have been caught.
It does bug me that people think they are supporting Open Source when in fact
they are just giving money to some con artist.

About a month ago, Montana was asking about inexpensive local hosting
services. While this one isn't local, and may not be exactly what he
wanted, some of you may find this useful. Their pricing for some of the
services are not bad...

The Manitoba UNIX User Group (MUUG) will be holding its next monthly
meeting on Tuesday, January 13. The meeting topic for this month is
as follows:
RT: Request Tracker
RT is an enterprise-grade ticketing system under developent since
1996 which enables a group of people to intelligently and
efficiently manage tasks, issues, and requets submitted by a
community of users.
RT has undergone a lot of development in the last few years that
makes it even more flexible …
[View More]and usable for everyone from 1-man
"teams" to 10,000-strong communities, from tracking my shopping list
(OK, maybe not...) to streamlining tech support and customer contact
for huge enterprises.
"How do you take an disorganized, overworked, overstressed, and
unmanagable sysadmin in a small company and make him an organized
and managable sysadmin? Install RT and tell him that if it's not in
RT it doesn't exist." - Paolo Supino, Telmap
Adam Thompson has researched, evaluated and implemented ticketing
systems from software defect-management to customer management and
everything in between, for over ten years. So far RT is the most
flexible solution he's found and has personally used it for both his
personal ToDo list and network infastructure servicing 10,000+
clients.
The group holds its general meetings at 7:30pm on the second Tuesday of
every month from September to June. (There are no meetings in July and
August.) Meetings are open to the general public; you don't have to be a
MUUG member to attend.
**********************************************************************
Please note our meeting location: The IBM offices, at 400 Ellice Ave.
(between Edmonton and Kennedy). When you arrive, you will have to
sign in at the reception desk, and then wait for someone to take you
(in groups) to the meeting room. Please try to arrive by about 7:15pm,
so the meeting can start promptly at 7:30pm. Don't be late, or you may
not get in. (But don't come too early either, since security may not
be there to let you in before 7:15 or so.) Non-members may be required
to show photo ID at the security desk.
Limited parking is available for free on the street, either on Ellice
Ave. or on some of the intersecting streets. Indoor parking is also
available nearby, at Portage Place, for $3.00 for the evening. Bicycle
parking is available in a bike rack under video surveillance located
behind the building on Webb Place.
