[gentoo-user] Gentoo User posting diagrams, graphics?

[James]

Hello,


So working on my new (proposed) security architecture, I need to post
some diagrams to make the questions more precise. I'm thinking about a
combination of firewall+nat and a transparent bridge-filter to prevent even
sophisticated (DDos) attacks from being successful. I use the gmane
front end to gentoo-user, so I guess the best/simplest technology for
diagrams starts with the use of  ascii_art ? 


It'd be very cool to at least use something like 'dia' or even more (color)
robust drawing tools? Folks like to keep all the pertinent info in the mail
posting, but using additional resources to put up fancy graphics, would be a
keen addition to gentoo_user, imho? Maybe  placing diagrams on a gentoo
manage resource or github?


Last, I'd like to end up with a Full Office type of example (DNS, mail and
web servers and LAN). To eventually migrate the information to  the  gentoo
wiki; so if the graphics and diagrams are gentoo wiki compatible, that would
be great.  I'd like to end up with the least steps for this. Or at least a
set of well defined filters/scripts to convert what I post to gentoo-user
into an acceptable form (jpeg?) that is easily displayed on the Gentoo wiki. 


Maybe something already exists? Maybe I should then file a bug to get wider
"buy-in" from the doc team? Ideas, discussion and examples are appreciated.

Most graphical mail clients don't display ascii_art correctly.

Personally, I don't care if people occasionally add a 
screenshot/drawing/whatever as attachment to emails if they are necessary to 
clarify the question and/or answer.

I think most commonly used graphical formats are supported.

Personally: JPEG or similar, high compression (not too much as to loose 
detail) and cropped to the minimal required.

I don't know if anything already exists.

However, if it is highly specific, a wiki-page or similar might be an option 
where interested parties collaborate with an occasional posting to the mailing 
list with specific questions or requests for comments?

Gmane forces editing so posting text is more than quoted text....

Huh. So ascii art is out as an option? I do not like it anyway for 
network diagrams purposes...

OK, what is available and what can we test? There are lots of examples
on the net [1,2]

Here is the idea I like best [3]. Diagrams, with "keys" that popup or
display the configuration of a particular component. These components can be
building blocks like nat, or ssh enable by ip address or protocol for example.

huh. Are there gentoo wiki examples where diagrams are currently used?

OK, so what tools/sequences/steps would somebody typically use to
get a (jpeg) diagram posted to say the gentoo-temp-diagram-server-buffer ?
What is the acceptable way to build gentoo wiki docs that have a mix of
diagrams and texts?

yes. Hopefully somebody knows of a public service or a web based service
where we can  experiment, then formulate a proposal to post to bgo?

Ideas on how to do this, are most welcome?

It just dawned on me that maybe we do not need a tool for users to
draw diagrams. What we need is say 5-10 reference diagrams posted on the
gentoo wiki.  Users can refer to the specific diagrams that mimics their
specific case as they formulate  and post their questions to the 
gentoo user mailing list. That way, only a small collection of diagrams
would have to appear on the gentoo wiki (or some place else if the g_devs
do not like the idea of network reference diagrams on their wiki)?


Furthermore, if the iptables and other code snippets are modularly designed,
one can use the components to create the firewall or bridge device
configurations.

I think it would be fine here, where hopefully anyone interested would
be able to configure his client to display with a monospace font.
Anybody having trouble with that, you could point to gmane's 
copy -- they use monospace for display.

I don't mind reading them, but they're a PiTA to create (unless there's
some good tool out there I don't know about).

I just tried to reply, keeping your 'trooley router' but gmane filtered
it out, no matter what I tried in response.

I thought the [] sq. brackets where 100Mbps ports and the tires (circles)
where gigabit ports....... And the tic at the back was an rF stub antennae.
And the double dashed line was your Bridge/filter (QoS/dDos)......?


(just teasing a bit),
