Please no! Setup 'sftp' instead. This does require two IPs on the
system since sftp (ftp over ssh) will take up one port because ideally
you'd setup virtual users who can't actually login to the system...

I'd think about Ansible, which lets you do repeatable test builds at
home. The trick, of course, is getting your email setup working that
way. There's a bunch of parts:
postfix for SMTP incoming/outgoing
dovecot for IMAP
postscreen
rspamd - spam filtering
dkim - for singing your outgoing emails
nginx - for hosting various files for google and others to check
for you being who you say you are. Fun fun.
And a bunch of other stuff. I'd actually suggest maybe you look at
https://mailinabox.email/ do you your setup. I think if I had to do
it again, i'd go that route.
The most important part though, and the most annoying, if getting your
VPS and making sure it's not in a spam block, or likely to get added
into one. Its... painful. I've been running stoffel.org for 20+
years now for email and it's gotten harder and harder.
Nowdays you need to have SPF keys setup in DNS, DKIM keys for signing
emails, you want to make sure you don't relay anything any more,
because that will get you banned. Which reminds me I need to stop
relaying too. Sigh...

Very true, a mail server is pretty low bandwidth.

If you're thinking of running this at home on your home internet then
you're in for probably a rude surprise. Most big mail providers tend
to block home IP blocks and not accept email because the volume of
spam from them is so high.
I'm on a Linode droplet right now, but thinking of moving to something
else.

Again, those AWS IP blocks tend to get blocked and dropped because of
the spam levels.

Happy to chat then. I'd suggest you going the postfix.org mailing
list and look through the archives. If you do go with a VPS, you'll
really want something with 2gb of RAM or more, because rspamd is a
hog. Postfix and dovecot are simple.
It's the getting others to accept your email that sucks.

Re: [Wlug] (no subject)
by Tim Keller
Here's my .02 cents on building a machine.
1. Memory. You can never have too much of it. I'd say try to get a board
that'll do 8GB with the expectation you'll be there at some point.
2. CPU: go duel at a minimum. If you could swing a quad I'd say go for it.
3. Video card: Get something that will do HDMI and is capable of duel head.
I've got a Nvidia GeForce 8400 GS with 512MB of video memory and it cost me
a whopping 40 dollars!
4. Harddrives: If your going to spring for 1, go ahead and buy two and then
mirror them. Mirrored drives have now saved my ass on three occasions.
5. Case: Honestly I like cases that don't resemble a disco under my desk.
I'm also fond of 120mm case fans. They move a shit load of air and are
quiet.
Power Supply: I wouldn't go smaller than a 350W. If you ever decide to
suddenly add two more drives or a burner, nothing sucks more than your power
supply being the weak link.
6. OS: Do it yourself. I'm not sure if Ubuntu will let you mirror drives at
install, I know the Red Hat family of distros will. Doing your own install
will at least give you an explicit understanding of what packages you've
installed. Heck we could probably make a meeting out of helping you install
and tweak your machine!
Later,
Tim.

Re: Uptime!
by Jon "maddog" Hall
Mike,
Believe it or not, both VMS and Digital Unix systems were the same way.
They would go months and years without rebooting.
The US Navy had two hospital ships, the "Mercy" and the "Hope". One
stationed on the East Coast and one in San Diego. The one on the East
Coast used WNT for the servers and the one in San Diego used GNU/Linux.
The ship using WNT had to have twice as many servers as the one in San
Diego because the Navy rules said that a WNT server HAD to be rebooted
every 30 days, whereas there was no such requirement for GNU/Linux. Since
a Naval deployment could last longer than 30 days, and since they needed
the server services to be up constantly that whole time, they needed twice
as many WNT servers.

Re: [Wlug] Gentoo
by John Platt
Just a couple of thoughts. 1. for a good commentary on the gentoo
handbook I recommend the blog postings of Vincent Zoonekynd. He's
French, he's modest and he's very insightful.
http://zoonek.free.fr/blosxom/Linux/2006-01-01_Gentoo.html
2. You can probably install it with a slax cd. Or a gentoo disk of
course. Either has a /proc/config.gz which will work very well with
genkernel to compile a kernel. After you have emerged genkernel type:
zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config-2.6
Then genkernel all to create a kernel and initramfs. Of course for a
64-bit machine you should zcat it to the appropriate subdirectory
which I believe is x86_64

Re: [Wlug] synce, is a wonderful thing

Yeah, I've figured out the boot-loader part....but I haven't been daring
enough to try it out. I was thinking about starting the process tonight, but
I couldn't get my win4lin installation to tell that I have a serial port on
my computer, and so I couldn't install the boot-loader. And since I can't
get synce to work right, I was kinda stuck.....
I can't wait until I get rid of pocketPC2002..... activesync is just a pain in

This commend is not meant to insult. Just that almost every distributions
are using cups. I have had request from my users that I should retro fit
lrpng into my network. Although it is not impossible, it is less versitile
than cups. I have not had much problems with both the applets and web based
configuration.

I totally agree. I would rather use the console command instead, but it is
nice to have an alternative configuration method for those who are not
confortable at the command line.

Have you considered connecting the printer to the windows box, share it and

Just a few reasons from my POV:
1) phones aren't available everywhere, and cell phone coverage is
spotty/dead in lots of areas. (for example, inside my company's
colo facility...)
2) it's quick and easy if you're already online. need to shoot a command
to someone or ask a quick 5 second question? it'll take me longer to
find/remember/dial their phone number than it is to goto my IM "buddy"
listing and type it.
3) unless you record it, there's no trail of conversations on the phone.
I "record" all IM conversations that I have -- really excellent to
remember little snippets of information. as an example, I opened a
hardware case with IBM the other day, but a coworker was going to be
the contact, so I IMed the case # to him. The next day, I needed to
call IBM about the case... Without having the conversation "recorded",
I'd have had no way to know what the case # was (didn't write it down,
and the coworker was unavailable). I've also done this type of thing
with conversations I had over a year ago. (this is the same reason
I pretty much save all email I send/receive btw...)
4) IM is good for multiple short conversations throughout the day --
my wife/friend/coworker can IM me in the morning, and I can just keep
the window open for any thoughts/questions/etc throughout the day.
5) If I'm not around, but someone IMs me a question, I'll see it when I
get back to my computer and can respond directly. If someone calls me
(see #6 below) I'd either have to tell them to call me back later when
I'm at my computer, or they'd leave me voice mail and I'd have to go
through the bother of getting the VM then calling back, etc, etc.
6) I can walk away from my IM window and get lunch or something --
if people knew my cell phone number, I'd have yet another electronic
leash.
7) I pay for phone calls, I don't pay for IM. If I'm using my home
phone (pay per call + per minute) or my cell phone (pay per minute),
that costs me money that I normally wouldn't have to pay... Not to
mention the fact that sometimes you want to talk to people who
aren't local which costs more money. However, I'm already paying
for bandwidth no matter how much I use.
8) I usually type more "correctly" than I talk.
9) I spend a lot of time working on open source software (one program
specifically), and sometimes need to converse with other developers
on the project. I'm here in MA, some are in CA, some in Canada,
some in Germany, etc... It's easier to IM than setup a multi-country
conference call.
10) if you're on the phone and want to talk to someone else either
about the call or something different, then you'd have to hang up
and call someone else, or get multiple phones, or ... an example:
I was on a con call with several of the above mentioned open source
developers, and the legal department of a large company we're
conversing with -- but we (developers) wanted to chat during the
call without having the other group overhear, so we had an IM chat
session going in the background.
11) I don't like using the phone. :P
I don't think IM is a replace-all for phones or in-person meetings,
but it does better handle/allow a lot of communications in a more
efficient manner. IMHO.

Re: Dec meeting.. not the 14th! 21st or 28th?
by Althea Shaheen
What I do is have the wireguard clients be on a different subnet than my other hosts, all behind the firewall. Then, in pfsense I made wireguard an interface like any other, and that allows me to make firewall policies, such as letting wireguard clients only to my DNS servers on port 53, or my web servers on 443. Also, since each wireguard client has a static IP reserved, I can make my phone access more than my cloud server, since I trust the security of my phone a tad more (but only a tad).
For routing, I have the config for the clients either as 0.0.0.0/0 to send all traffic over the tunnel, or my private networks only for the split tunnel, and let the firewall policy handle it from there.
So, you could certainly make it so that your VPS connects to your wireguard endpoint, and then send your backup traffic to it's client IP if you are going outbound to the VPS, and block the VPS from your internal network, or vice versa just open up the port you need to the host you need from the VPS to internal.
Hope this helps

Re: [Wlug] Fw: RE: show
by Matthew Kwiatkowski
I think this sounds like it's turning into an interesting idea. I would
be willing to help out as a cameraman or something behind the scenes,
and I do have a laptop with video out, but I would need a ride from
campus to the studio. I will also be home on break the week of the
21st, so I can't make that night.
